Infusion pumps in the prior art generally have a real-time pressure monitoring system, so that medical staff can conveniently acquire the current infusion pressure and know the infusion condition, and meanwhile, after an infusion pipeline is blocked, certain help is provided for the treatment of blocking alarm.

When the blockage alarm is processed, medical staff cannot know whether the threshold needs to be adjusted or not and adjust the threshold properly because of the non-intuition of real-time pressure, and even when the problem which cannot be solved is met, the medical staff can only call the manufacturer to adjust the pressure threshold.

The infusion pump 100 may be used with an infusion set (e.g., tubing, syringe). It should be understood that infusion pump 100 is only one example, and that its components may have more or fewer components than shown, or a different configuration of components. The various components described in conjunction with fig. 1 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. In certain embodiments, the memory 104 may also include memory remote from the one or more processors 150, such as network-attached memory accessed via the RF circuitry 120 or the external port 122 and a communication network (not shown), which may be the internet, one or more intranets, a Local Area Network (LAN), a wide area network (WLAN), a Storage Area Network (SAN), etc., or a suitable combination thereof. The processor 150 may control access to the memory 104 by other components of the infusion pump 100 other than the peripheral interface 152.

The peripheral interface 152 couples the input and output peripherals of the infusion pump 100 to the processor 150 and the memory 104. The one or more processors 150 execute various software programs and/or sets of instructions stored in the memory 104 to perform various functions of the infusion pump 100 and process data.

In some embodiments, peripheral interface 152 and processor 150 may be implemented on a single chip. And in some embodiments they may be implemented on multiple discrete chips.

The RF (radio frequency) circuit 120 receives and transmits electromagnetic waves. The RF circuit 120 converts an electrical signal into an electromagnetic wave or converts an electromagnetic wave into an electrical signal and communicates with a communication network and other communication devices via the electromagnetic wave. The RF circuitry 120 may include well-known circuitry for performing these functions, including but not limited to an antenna system, an RF transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a CODEC chipset, a Subscriber Identity Module (SIM) card, memory, and so forth. The RF circuitry 120 may communicate with networks and other devices via wireless communications, the networks may be the World Wide Web (WWW), an intranet, and/or a wireless network such as a cellular telephone network, a wireless Local Area Network (LAN), and/or a Metropolitan Area Network (MAN). The wireless communication may use any of a variety of communication standards, protocols, and technologies, including, but not limited to, global system for mobile communications (GSM), Enhanced Data GSM Environment (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), bluetooth (e.g., IEEE802.15.1), wireless fidelity (WIFI) (e.g., IEEE802.11a, IEEE802.11 b, IEEE802.11g, and/or IEEE802.11n), voice over internet protocol (VoIP), Wi-MAX, protocols for email, instant messaging, and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed on the filing date herein.

The external port 122 provides a wired communication interface between the infusion pump 100, other devices (e.g., a mounting Dock, a central station, a monitor, etc.), or a user (a computer or other communication device). In some embodiments, it may be a communication interface controlled by a CAN bus protocol, a communication interface controlled by a serial communication protocol (e.g., RS485, RS232), or a Universal Serial Bus (USB). The external port 122 is adapted to couple to other devices or users either directly or indirectly via a network (e.g., the internet, LAN, etc.).

The audio circuit 124 and speaker 154 provide an audio interface between the user and the infusion pump 100. Audio circuitry 124 receives audio data from peripheral interface 152, converts the audio data to electrical signals, and transmits the electrical signals to speaker 154. The speaker 154 converts the electrical signals into sound waves that are perceivable to humans.

The monitoring circuitry 126 may include fault detection circuitry to indicate the status of one or more processors 150.

The protection circuit 128 may include hardware protection devices (e.g., fuses, TVS diodes) for protecting the electrical safety of various components within the infusion pump 100.

The processor 150 drives a driving mechanism (not shown) of the infusion pump 100 through the power driving circuit 130, so that the driving mechanism controllably moves under the driving of the processor 150, and drives a control object (such as a pump door, a liquid stopping clip, a peristaltic squeezing mechanism or a push-pull box) to move through one or more force transmission/conversion devices (such as gears, transmission shafts, lead screws, nuts or sliders) during the movement. The driving mechanism may be an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction, such as a Permanent Magnet (PM) motor, a reactive (VR) motor, and a Hybrid (HB) motor. In some embodiments, the motor, driven by the processor 150, moves a control object (e.g., a pump door, a liquid stop clip, a pump sheet, or a push-pull cassette) of the infusion pump 100 to achieve a preset movement state of the control object.

In some embodiments, as shown in fig. 1 and 2, the peristaltic compression mechanism 200 includes a cam shaft 208, a set of pump plates 210, and a compression plate 212. The processor 150 in the infusion pump 100 sends out instructions such as a rotating speed or a position, and drives the driving mechanism 214 (for example, a motor) to operate according to a specified rotating speed and a specified rotating direction through the power driving circuit 130, and the driving mechanism 214 drives the camshaft 208 connected with the driving mechanism to rotate in the rotating process; during the rotation of the camshaft 208, the pump blade group 210 on the camshaft 208 performs a linear reciprocating motion, that is, the pump blades on the pump blade group 210 sequentially perform a linear reciprocating motion. The pump plate set 210 cooperates with the pressing plate 212 to sequentially and reciprocally press and release the outer wall of the infusion tube 218, so as to drive the liquid in the infusion tube 218 to continuously flow in a directional manner. A speed reducing mechanism may be further disposed between the driving mechanism 214 and the camshaft 208 to ensure that the rotation speed of the pump blade set 210 is stable and uniform.

In some embodiments, as shown in fig. 1 and 3, the infusion set is a syringe 312. The push-pull box 308 is used to hold the plunger 314 of the syringe 312. The processor 150 in the syringe pump 100 sends out instructions such as rotation speed or position, drives a driving mechanism (e.g., the motor 300) through the power driving circuit 130, the motor 300 drives the screw 302 and the nut 304 through the speed reducing mechanism, the rotation motion of the motor 300 is converted into the linear motion of the nut 304, the nut 304 is connected with the push rod 306 of the matched syringe 312, the push rod 306 is connected with the push-pull box 308, the push-pull box 308 can push the piston 314 of the matched syringe 312 to perform injection and transfusion, and the pushing speed of the matched syringe 312 can be adjusted by setting the rotation speed of the motor 300, so that the given infusion dosage and the infusion speed can be adjusted.

In some embodiments, the drop count sensor 132 may be used with a drip cup 220 of the infusion set 206 for detecting the drop flow rate or flow in the drip cup 220.

In some embodiments, one or more bubble sensors 134 are used to detect the presence and magnitude of gas within the infusion set. The bubble sensor 134 may be an ultrasonic sensor or an infrared sensor, etc.

In some embodiments, the pressure sensor 136 may respond to a pressure value of the measurand and convert the pressure value into an electrical signal for detection and send to the control platform 102. The pressure sensor may be a resistive strain gauge pressure sensor, a semiconductor strain gauge pressure sensor, a piezoresistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, a resonant pressure sensor, a fiber optic pressure sensor, or a capacitive acceleration sensor. In some embodiments, the pressure sensor 136 may be used to detect the internal pressure of the infusion set or the external pressure of the infusion set. In some embodiments, the pressure sensor 136 may also be used to detect the presence of the object under test (e.g., the infusion tube 218 or the syringe 312). In some embodiments, the pressure sensor 136 may detect an occlusion inside the infusion set, or detect if the infusion set is leaking.

In some embodiments, the infusion pump 100 has a heating device to heat the fluid in the infusion set, where the temperature sensor 138 may be used to detect the real-time temperature of the fluid; meanwhile, the temperature value is converted into an electric signal for detection and sent to the control platform 102, and the control platform 102 can display the real-time temperature through the display system 160 and can also perform on/off control on the heating device according to the temperature value.

An input/output (I/O) system 108 provides an interface between input/output peripherals of the infusion pump 100 and a peripheral interface 152. The input/output peripherals may be a display system 160, position sensors 164, displacement sensors 166, light assemblies 168, and other input/control devices 162. The I/O system 108 may include a display controller 140, a position sensor controller 144, a displacement sensor controller 146, a light controller 148, and one or more other input controllers 142. One or more controllers in the I/O system 108 receive/transmit electrical signals from/to input/output peripherals. Where one or more input controllers 142 receive/transmit electrical signals from/to other input/control devices 162. The other input/control devices 162 may include physical buttons (e.g., push buttons, rocker buttons, touch buttons, etc.), slider switches, joysticks, and the like. In some embodiments, other input/control devices 162 may include a physical button for emergency stop of infusion.

In some embodiments, as shown in fig. 1, 4A, 4B, and 4C, display system 160 may include at least one display screen, such as display screen 402 in fig. 4A, such as display screen 414 in fig. 4B, such as display screen 434 in fig. 4C. The display screen provides an output interface between the infusion pump 400/syringe pump 410/syringe pump 430 and the user, which provides a visual display interface. In some embodiments, the display 402/414/434 may be a touch screen that includes a touch panel and a display panel in a stacked arrangement that provides an input/output interface between the infusion pump 400/syringe pump 410/syringe pump 430 and a user; the touch panel may include a resistive screen, a surface acoustic wave screen, an infrared touch screen, an optical touch screen, a capacitive screen, or a nano-film, and is an inductive display device that can receive input signals such as a contact. The visual output optionally includes graphics, text, charts, video, and combinations thereof. Some or all of the visual output may correspond to user interface objects.

The touch screen may also receive user input based on tactile sensation and/or contact. The touch panel of the touch screen forms a touch sensitive surface that receives user input. The touch panel and display controller 140 (along with any associated modules and/or sets of instructions in memory 104) detects contact (and any movement or breaking of the touch) on the touch panel and translates the detected contact into interaction with user interface objects, such as one or more soft keys, displayed on the touch panel. In one exemplary embodiment, the point of contact between the touch panel and the user corresponds to one or more fingers of the user. The touch panel may use LCD (liquid crystal display) technology or LPD (light emitting polymer display) technology, but in other embodiments other display technologies may be used. Touch panel and display controller 140 may detect contact and movement or breaking thereof using any of a number of touch sensitive technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays, or other technologies for determining one or more points of contact with the touch panel.

The position sensor 164 may sense the position of the measurand and convert the position to a detectable electrical signal and send the electrical signal to the control platform 102 via the I/O system 108. The position sensor can be a contact sensor which generates signals by contact and extrusion of two objects, such as a travel switch and a two-dimensional matrix position sensor; or a proximity sensor that generates a signal by the proximity of two objects to a predetermined distance, such as an electromagnetic type, a photoelectric type, a differential transformer type, an eddy current type, a capacitor type, a reed switch, an ultrasonic type, or a hall type. The object to be measured can comprise an infusion apparatus, a pump door, a pump sheet, a liquid stopping clamp, a push rod and the like. In some embodiments, a Hall position sensor may be used to detect the position of the pump door. In some embodiments, an electro-optical position sensor may be used to detect the position of the pump blade. In some embodiments, an electro-optical position sensor may be used to detect whether the infusion set is set in a predetermined position. In some embodiments, an optoelectronic position sensor may be used to detect the position status of the clamping mechanism of the syringe. In some embodiments, the position of the clamping tube of the liquid stop clamp can be detected by using an optoelectronic position sensor.

The displacement sensor 166 may be responsive to a change in position of the object being measured relative to the reference position and convert the change in position to a detectable electrical signal and transmit the electrical signal to the control platform 102 via the I/O system 108. The displacement sensor 106 may be inductive, capacitive, ultrasonic, or hall. In some embodiments, a potentiometer may be used to monitor the change in position of the pump door. In some embodiments, a potentiometer may be used to monitor the change in position of the slide of the syringe pump. In some embodiments, a rotary potentiometer may be used to monitor changes in the outer diameter of an infusion set (e.g., a syringe).

The light assembly 168 may include a visual alarm element for alerting the infusion pump 100 of an abnormal condition. The light assembly 168 is solely responsive to actuation of the processor 150; the light assembly 168 may also be correspondingly engaged with the speaker 154 in response to activation of the processor 150, such as a light that changes color or intensity with the tone, frequency, or duration of the warning sound. The light assembly 168 may include an indicator light or a fluid delivery fault condition warning light for components such as a power source, CPU, etc. The light assembly 168 may also include visual illumination elements for facilitating viewing of the structure or assembly status of the infusion pump 100 in the event of poor ambient light.

The infusion pump 100 also includes a power supply system 106 for powering the various components. The power system 106 may include a power management system, one or more power sources (e.g., batteries or Alternating Current (AC)), a charging system, power failure detection circuitry, a power converter or inverter, a power status indicator (e.g., a Light Emitting Diode (LED)), and may include any other components associated with power generation, management, and distribution.

In some embodiments, the software components include an operating system 170, a communication module (or set of instructions) 172, a touch module (or set of instructions) 174, a haptic feedback module (or set of instructions) 176, a motion module (or set of instructions) 178, a location module (or set of instructions) 180, a graphics module (or set of instructions) 182, a text input module (or set of instructions) 190, a device/global internal state (or set of instructions) 192, and one or more applications (sets of instructions) 194.

The operating system 170 (e.g., Darwin, RTXC, LINUX, UNIX, OS, WINDOWS, etc. embedded operating systems) includes various software components and/or drivers for controlling and managing conventional system tasks (e.g., memory management, storage device control, or power management, etc.) as well as facilitating communication between the various software and hardware components.

The communication module 172 facilitates communication with other devices via one or more external ports 122, and it also includes various software components for processing data received by the RF circuitry 120 and/or the external ports 122.

In some embodiments, the touch module 174 may selectively detect contact with the display system 160 or other touch-sensitive device (e.g., touch buttons, touch pads). For example, the touch module 174 in conjunction with the display controller 140 detects contact with the display system 160. The touch module 174 includes various software components for performing various operations associated with detection of contact (which may be by a finger or stylus, etc.) by the display system 160, such as determining whether contact has occurred (e.g., detecting finger press time), determining the strength of contact (e.g., force or pressure of contact), determining whether the contact has moved (e.g., detecting one or more finger drag events), and tracking movement across the touch screen and determining whether the contact has ceased (e.g., detecting finger lift time or contact breaking). The operation in which the movement of the point of contact is determined may include determining a velocity (magnitude), a velocity (magnitude and direction), and/or an acceleration (including magnitude and/or direction) of the point of contact. These operations may be applied to single point contacts or multiple simultaneous contacts. In some embodiments, the touch module 174 in conjunction with the display controller 140 detects contact by other touch devices.

The touch module 174 may be used to detect gesture input by a user. Different gestures by the user on the touch-sensitive device have different contact patterns (e.g., one or more combinations of locations, times, or intensities at which contacts are detected). For example, detecting a single-finger tap gesture includes detecting a finger-down event and then detecting a finger-up event at the same or a similar location as the finger-down event. For example, detecting a finger swipe gesture on the surface of the touch device includes detecting a finger-down event, then monitoring for one or more finger-dragging events, and then detecting a finger-up event. Similarly, taps, swipes, drags, and other gestures of the stylus are optionally detected by detecting a particular contact pattern of the stylus.

The tactile feedback module 176 includes various software components for generating instructions to produce tactile outputs at one or more locations of the infusion pump 100 using one or more tactile output generators (not shown) in response to user interaction with the infusion pump 100. For example, after detecting contact with the surface of the touch device, the color of the graphics or text of the touch device changes, or sound or vibration is generated.

The location module 180 includes software components for performing various operations related to detecting device location and detecting changes in device location.

Graphics module 182 includes various known software components for rendering or displaying graphics on a display screen of display system 160 or other external device, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual attributes) of the displayed graphics. In embodiments herein, the term "graphics" includes any object that may be displayed to a user, including without limitation text, web pages, icons (e.g., user interface objects for soft keys), digital images, videos, animations, and the like. In some embodiments, the graphics module 182 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. The graphic module 182 receives one or more codes for specifying a graphic to be displayed from an application program or the like, and also receives coordinate data and other graphic attribute data together if necessary, and then generates screen image data to output to the display controller 140.

Certainly, in order to achieve a better touch effect of the user, the display screen included in the display system is a touch screen.

In some embodiments, the main components of the infusion pump are disposed in the pump body, and the pump door is movably mounted on the pump body to cover the receiving cavity for mounting the infusion set, and sometimes the receiving cavity for mounting the infusion set can be exposed when the user opens the pump door. The pump door has a front face facing the user (exterior) and side faces that can be used to mate with the mounting bracket, as well as top and bottom faces that can be used to face other infusion pumps in a stacked arrangement. The display system is arranged on the pump door, extends from the left side of the center line of the front face of the pump door to the right side of the center line of the front face of the pump door, is wider than the display system, and is integrally arranged on the pump door in a long strip shape.

Certainly, the physical input keys can be used for infusion control through the physical input keys when the touch screen fails and infusion control cannot be performed in emergency, so that the use safety of the infusion pump is ensured.

An embodiment of the present application provides an infusion pump 100 for displaying occlusion pressure, the infusion pump 100 being used with an infusion set, as shown in fig. 1, 5 to 8, the infusion pump 100 comprising: drive mechanism 214, display system 160, pressure sensor 136, processor 150, memory 104, display module, and display controller 140.

The display system 160 includes at least one touch screen including a touch panel and a display panel.

The pressure sensor 136 is configured to detect a pressure parameter in the infusion set.

The processor 150 is configured to retrieve an occlusion pressure threshold, which may include a default occlusion pressure threshold of the infusion pump 100, i.e., a configured occlusion pressure threshold within the infusion pump 100, receive and respond to operator commands entered via the display system 160 to determine a first occlusion pressure threshold corresponding to the operator commands, or receive a second occlusion pressure threshold entered via an external port of the infusion pump 100, e.g., via a device such as a usb disk connected to the external port.

The memory 104 is configured to store the pressure parameter and to store at least one of a default occlusion pressure threshold, a first occlusion pressure threshold, and a second occlusion pressure threshold.

A display module is coupled to the processor 150, the display module configured to generate an occlusion pressure display graph 512-1, the occlusion pressure display graph 512-1 comprising: the graphic carrier 512-1a, the graphic carrier 512-1a at least comprises a blocking pressure safety area and a blocking alarm area; a numerical display 512-1b of the most recently detected pressure parameter and a first visual indicia 512-1c corresponding to the most recently detected pressure parameter; the numerical value display 512-1d of the occlusion pressure threshold value or the second visual identifier 512-1e corresponding to the occlusion pressure threshold value, that is, only the numerical value display 512-1d of the occlusion pressure threshold value, only the second visual identifier 512-1e corresponding to the occlusion pressure threshold value, and both the numerical value display 512-1d of the occlusion pressure threshold value and the second visual identifier 512-1e corresponding to the occlusion pressure threshold value may be displayed in the occlusion pressure display graph 512-1; a third visual indicator 512-1f indicating that the cue is approaching the occlusion pressure threshold; the projection position or the projection area of the second visual identifier 512-1e on the graphic carrier 512-1a and the blockage warning area at least indicate the starting point of the blockage warning area, that is, the projection position or the projection area of the second visual identifier 512-1e on the graphic carrier 512-1a may only indicate the starting point of the blockage warning area, and may also indicate the whole course of the blockage warning area; the projected position or projected area of the third visual marker 512-1f on the graphic carrier 512-1a overlaps with the occlusion pressure safety area, and the projected positions or projected areas of the second visual marker 512-1e and the third visual marker 512-1f on the graphic carrier 512-1a are independent of each other, that is, if the second visual marker 512-1e is provided, the projected positions or projected areas of the second visual marker 512-1e and the third visual marker 512-1f on the graphic carrier 512-1a are not overlapped.

Specifically, taking the third visual indicator 512-1f as an example, the projection position or the projection area described herein mainly includes two cases that the third visual indicator 512-1f is directly disposed on the graphic carrier 512-1a, and the third visual indicator 512-1f is not directly disposed on the graphic carrier 512-1 a. When the third visual identifier 512-1f is directly disposed on the graphic carrier 512-1a, the specific position or area of the third visual identifier 512-1 on the graphic carrier 512-1a is the corresponding projection position or projection area, or at this time, the third visual identifier 512-1 covers the projection position or projection area of itself on the graphic carrier 512-1 a; when the third visual indicator 512-1f is not directly disposed on the graphic carrier 512-1a, i.e., there is a certain gap between the third visual indicator 512-1f and the graphic carrier 512-1a, the projection of the third visual indicator 512-1f on the graphic carrier 512-1a is the projection position or the projection area corresponding to the third visual indicator 512-1 on the graphic carrier 512-1 a.

The projection positions or projection areas of the various numerical displays and the various visual marks described in the present application have the same meaning as that represented by the projection position or projection area of the third visual mark 512-1f described above, and are not described herein again.

Taking the infusion pump as an example, the display mode and the setting of the injection pump are substantially the same as those of the infusion pump, and are not described herein again. In some embodiments, as shown in fig. 5, the processor presents an image comprising a plurality of infusion parameter settings 510 in a display panel 502 of a display system of an infusion pump 500, wherein the plurality of infusion parameter settings 510 may comprise a medication name setting, a flow rate value setting, a flow rate unit setting, an infusion mode setting, a consumable setting, a remaining amount setting, and a remaining time setting. Also included in display panel 502 are images of multiple reading items 512, one of which is an occlusion pressure display graphic. Additionally, images of a plurality of control items 514 may also be included in the display panel 502, wherein the plurality of control items 514 include a push control item 516-1 and a pause control item 516-2.

As shown in fig. 5 to 9I, the graphic carrier 512-1a is mainly used for providing the second visual mark 512-1E and the third visual mark 512-1F, and the graphic carrier 512-1a may be a circular arc as shown in fig. 6, 8, 9A to 9B, a linear type as shown in fig. 9C to 9E, or a stepped type as shown in fig. 9F to 9I, and more specifically, the graphic carrier 512-1a may be a circular arc in a sectional type as shown in fig. 6 and 8, a linear shape in a sectional type as shown in fig. 9D, or a stepped type as shown in a sectional type as shown in fig. 9F, 9G and 9I, or may be a circular arc in an increasing size as shown in fig. 9B, a linear shape in an increasing size as shown in fig. 9E, or a stepped type as shown in fig. 9I.

The first visual identifier 512-1c may be dynamically changed correspondingly with the change of the latest detected pressure parameter, and the second visual identifier 512-1e and the third visual identifier 512-1f may be kept still all the time, wherein the third visual identifier 512-1f mainly plays a role of warning, that is, when the first visual identifier 512-1c and the third visual identifier 512-1f which are dynamically changed correspond to each other, for example, when the first visual identifier 512-1c and the third visual identifier 512-1f overlap, it indicates that the pressure in the current infusion set is about to reach the occlusion pressure threshold.

It should be noted that the third visual identifier 512-1f is only used for reminding an operator that the pressure parameter is about to approach the occlusion pressure threshold, and in practical applications, the third visual identifier 512-1f may be a numerical range approaching the occlusion pressure threshold, and the numerical range may be set empirically without corresponding to a specific numerical value, as long as it is ensured that the third visual identifier 512-1f can play a role in warning.

The display controller 140 is configured to output the occlusion pressure display graphic 512-1 into the display system 160.

Specifically, the blocking pressure display graphic 512-1 may be output to a touch screen having a touch panel and a display panel, or to another display screen having only a display panel without a touch panel.

The processor 150 is further configured to control the display module to adjust the occlusion pressure display graph 512-1 during operation of the driving mechanism 214 such that the numerical display 512-1b of the most recently detected pressure parameter in the occlusion pressure display graph 512-1 changes in synchronization with the first visual indicator 512-1c corresponding to the most recently detected pressure parameter, corresponding to the first visual indicator 512-1c being correspondingly dynamically changeable with changes in the most recently detected pressure parameter during operation of the driving mechanism 214.

The present embodiment generates the occlusion pressure display graphic 512-1 representing the occlusion pressure on the display panel of the display system 160, and the occlusion pressure display graphic 512-1 includes: a graphics carrier 512-1a, the graphics carrier 512-1a comprising a occlusion safe area and an occlusion alarm area; a numerical display 512-1b of the most recently detected pressure parameter and a first visual indicia 512-1c corresponding to the most recently detected pressure parameter; a numerical display 512-1d of the occlusion pressure threshold or a second visual indicia 512-1e corresponding to the occlusion pressure threshold; the third visual identifier 512-1f for indicating that the prompt is close to the blocking pressure threshold can intuitively display the current pressure parameter, and a blocking safety region and a blocking alarm region are arranged on the same graphic carrier 512-1a, so that a user can clearly and directly know the region where the current pressure parameter is located, and the user can also visually see the change trend of the blocking pressure (the direction from the blocking safety region to the blocking alarm region), thereby directly knowing whether the current pressure parameter is in or close to the blocking alarm region, so that the operator can understand the content and the representative meaning of the blocking pressure display graphic 512-1 without learning in advance, particularly the third visual identifier 512-1f can play a role of warning in advance when the newly detected pressure parameter is about to reach the blocking pressure threshold, so that the operator can take corresponding countermeasures in advance, and the driving mechanism can be adjusted in a hurry only when the driving mechanism stops working without waiting for triggering the alarm.

In some embodiments, the processor 150 is further configured to actuate the driving mechanism 214 to stop operating when the value of the latest detected pressure parameter exceeds the value of the occlusion pressure threshold, and control the display module to adjust the occlusion pressure display graph 512-1 such that the projection position or the projection area of the first visual marker 512-1c on the graphic carrier 512-1a overlaps or is reversed in order with the projection position or the projection area of the second visual marker 512-1e on the graphic carrier 512-1a in the adjusted occlusion pressure display graph 512-1. That is, the occlusion pressure display graph 512-1 at this time visually displays that the value of the newly detected pressure parameter has exceeded the value of the occlusion pressure threshold, so that the operator can timely know the reason why the driving mechanism 214 stops working.

In some embodiments, the processor 150 is further configured to cause the driving mechanism 214 to reverse when the value of the latest detected pressure parameter exceeds the value of the occlusion pressure threshold, specifically, the driving mechanism 214 may be stopped before the reverse rotation, the driving mechanism 214 is caused to reverse again, the driving mechanism 214 is caused to reverse for a predetermined number of turns when the driving mechanism 214 reverses to cause the value of the latest detected pressure parameter to fall to the preset value, or the driving mechanism 214 is caused to stop working when the value of the latest detected pressure parameter falls to the preset value, and the display module is controlled to adjust the occlusion pressure display graph 512-1 so that the projection position or the projection area of the first visual identifier 512-1c on the graph carrier 512-1a corresponds to the preset value in the adjusted occlusion pressure display graph 512-1. That is, when the value of the newly detected pressure parameter exceeds the value of the occlusion pressure threshold, the processor 150 may reverse the driving mechanism 214 to lower the value of the newly detected pressure parameter to a relatively safe preset value, so that a certain safety protection may be performed by the driving mechanism 214 when an occlusion occurs to avoid a more serious condition.

In some embodiments, occlusion pressure display graphic 512-1 includes a numerical display 512-1d of occlusion pressure thresholds. As shown in FIG. 11, the processor 150 is further configured to cause the drive mechanism 214 to deactivate and display a occlusion alarm interface 512-3 when the value of the newly detected pressure parameter exceeds the value of the occlusion pressure threshold, the occlusion alarm interface 512-3 providing a quick access 512-3a for occlusion pressure threshold setting and occlusion alarm information; in response to a trigger event of the shortcut portal 512-3a, displaying a blocking pressure threshold setting interface, wherein the blocking pressure threshold setting interface comprises a plurality of editing items of the blocking pressure threshold; the occlusion pressure display graph 512-1d of occlusion pressure thresholds in the occlusion pressure display graph 512-1 is updated according to the selected value of the occlusion pressure threshold or the level of the occlusion pressure threshold upon detection of a triggering event based on an edit to one of the occlusion pressure thresholds.

That is, instead of the occlusion pressure display graphic 512-1 displaying the value of the newly detected pressure parameter that has exceeded the value of the occlusion pressure threshold, the occlusion alarm interface 512-3 may be displayed directly when the value of the newly detected pressure parameter exceeds the value of the occlusion pressure threshold. The related blockage alarm information can be directly displayed to an operator through the blockage alarm interface 512-3, and the operator can also adjust the current blockage pressure threshold through the quick inlet 512-3a for setting the blockage pressure threshold on the blockage alarm interface 512-3, so that the convenience of handling the blockage alarm by the operator can be improved.

In some embodiments, the first visual indicia 512-1c, the second visual indicia 512-1e, and the third visual indicia 512-1f are shape symbols or color indicia, i.e., the first visual indicia 512-1c, the second visual indicia 512-1e, and the third visual indicia 512-1f may all be shape symbols, may all be shape symbol color indicia, or may be a combination of shape symbols and color indicia, thereby facilitating an operator to intuitively understand what the occlusion pressure display graphic 512-1 represents without spending time to learn and understand.

In some embodiments, as shown in FIGS. 5-9I, the first visual indicia 512-1c, the second visual indicia 512-1e, and the third visual indicia 512-1f are shape symbols. During operation of the drive mechanism 214, the first visual indicia 512-1c, the second visual indicia 512-1e, and the third visual indicia 512-1f change between a separated state and an overlapped state relative to the projection position or projection area, respectively, of the graphic carrier 512-1 a. For example, according to the difference of the latest detected pressure parameters, when the projection positions or projection areas of the first visual identifier 512-1c, the second visual identifier 512-1e and the third visual identifier 512-1f are separated from each other, the real-time pressure of the current pipeline is low, the infusion is smooth, and no blocking tendency occurs; when the projection position or the projection area of the first visual marker 512-1c is overlapped with the projection position or the projection area of the third visual marker 512-1f, the real-time pressure of the current pipeline is high, the infusion is smooth, and the blockage can occur; when the projected position or area of the first visual marker 512-1c overlaps the projected position or area of the second visual marker 512-1e, it indicates that the current real-time pressure of the pipeline is too high, and an occlusion is triggered and needs to be immediately treated. By configuring the first visual indicator 512-1c, the second visual indicator 512-1e, and the third visual indicator 512-1f to change between the separated state and the overlapped state with respect to the projection position or the projection area of the graphic carrier 512-1a, respectively, it is possible to facilitate the operator to intuitively understand which pressure range the newly detected pressure parameter is in, so as to facilitate the operator to take corresponding countermeasures.

It should be noted that, in the above embodiment, the projection positions or the projection areas of the second visual marker 512-1e and the third visual marker 512-1f are always separated, but the first visual marker 512-1c may change its projection position or projection area, so that the projection position or the projection area of the first visual marker 512-1c can be separated from or overlapped with the projection positions or the projection areas of the second visual marker 512-1e and the third visual marker 512-1 f.

In some embodiments, the first visual indicia 512-1c, the second visual indicia 512-1e, and the third visual indicia 512-1f are shape symbols. In the working process of the driving mechanism 214, the sequences of the first visual identifier 512-1c, the second visual identifier 512-1e and the third visual identifier 512-1f with respect to the projection position or the projection area of the graphic carrier 512-1a are changed, for example, according to the difference of the latest detected pressure parameters, when the projection positions or the projection areas of the first visual identifier 512-1c, the second visual identifier 512-1e and the third visual identifier 512-1f are sequentially sequenced, the real-time pressure of the current pipeline is low, the infusion is smooth, and no blocking tendency occurs; when the projection positions or projection areas of the second visual identifier 512-1e, the first visual identifier 512-1c and the third visual identifier 512-1f are sequenced in sequence, the real-time pressure of the current pipeline is high, the infusion is smooth, and the blockage may occur; when the projection positions or projection areas of the second visual identifier 512-1e, the third visual identifier 512-1f and the first visual identifier 512-1c are sequentially sequenced, it indicates that the current pipeline has overlarge real-time pressure, and is required to be immediately processed after the blockage is triggered. By arranging the first visual indicator 512-1c, the second visual indicator 512-1e, and the third visual indicator 512-1f to change in order with respect to the projection position or projection area of the graphic carrier 512-1a, respectively, it is possible for the operator to intuitively understand which pressure range the newly detected pressure parameter is in, so that the operator can take corresponding countermeasures.

It should be noted that the above sequential sorting may be sequential sorting from left to right, sequential sorting from right to left, sequential sorting from top to bottom, sequential sorting from bottom to top, and the like. In practical applications, the projection positions or projection areas of the second visual marker 512-1e and the third visual marker 512-1f may be always kept unchanged, and the first visual marker 512-1c, the second visual marker 512-1e and the third visual marker 512-1f may be changed by changing their own projection positions or projection areas with respect to the order of the projection positions or projection areas of the graphic carrier 512-1 a.

In some embodiments, as shown in FIGS. 5-9I, a fourth visual indicator 512-1g is also provided in the graphic carrier 512-1a to indicate a safe pressure process. The projection positions or projection areas of the second visual marker 512-1e, the third visual marker 512-1f and the fourth visual marker 512-1g on the graphic carrier 512-1a are independent, namely the projection positions or projection areas of the second visual marker 512-1e, the third visual marker 512-1f and the fourth visual marker 512-1g on the graphic carrier 512-1a are non-overlapping.

Specifically, the fourth visual indicator 512-1g actually represents a value range of the pressure parameter, in which the pressure of the pipeline is small, the infusion is smooth, and there is no tendency of blockage, and in practical applications, when the projection position or the projection area of the first visual indicator 512-1c overlaps with the projection position or the projection area of the fourth visual indicator, it may represent that the newly detected pressure parameter is in the safe pressure range.

In some embodiments, the projected locations or areas of the second visual indicia 512-1e, the third visual indicia 512-1f, and the fourth visual indicia 512-1g on the graphic carrier 512-1a remain unchanged regardless of the occlusion pressure threshold, thereby facilitating the placement of the projected locations or areas of the second visual indicia 512-1e, the third visual indicia 512-1f, and the fourth visual indicia 512-1g on the graphic carrier 512-1 a. In some embodiments, the projected location or area of the second visual indicia 512-1e, the third visual indicia 512-1f, and the fourth visual indicia 512-1g on the graphic carrier 512-1a may also vary with a variation in the occlusion pressure threshold.

Further, in some embodiments, the second visual indicia 512-1e, the third visual indicia 512-1f, and the fourth visual indicia 512-1g are color indicia, and the fourth visual indicia 512-1g, the second visual indicia 512-1e, and the third visual indicia 512-1f are green, yellow, and red, respectively. Green, yellow and red are commonly used in daily life to represent safety, early warning and danger, so that an operator can easily identify which stage the current pipeline pressure is in according to which color the current first visual identifier 512-1c is overlapped with, and the identification mode is simple and convenient.

In some embodiments, the processor 150 may be further configured to control the display module to adjust the occlusion pressure display graph 512-1 when the value of the latest detected pressure parameter exceeds a preset approaching occlusion threshold value, so that the value display 512-1b of the latest detected pressure parameter changes in the adjusted occlusion pressure display graph 512-1, for example, the value display 512-1b of the latest detected pressure parameter may change font, color, or bold, etc., to give a more prominent prompt to the operator.

In some embodiments, occlusion pressure display graphic 512-1 further comprises: the display of the value of the minimum historical value of the pressure parameter during the previous time period and the display of the value of the maximum historical value of the pressure parameter during the previous time period, that is, the operator may see the display of the value of the minimum historical value and the display of the value of the maximum historical value on the occlusion pressure display graphic 512-1 to facilitate the operator comparing the display of the value of the newly detected pressure parameter 512-1b with the display of the value of the minimum historical value and the maximum historical value.

In some embodiments, occlusion pressure display graphic 512-1 further comprises: a history range indicator indicating a minimum history value and a maximum history value of the pressure parameter during a previous time period, the history range indicator may be some symbols such as a triangle symbol, an arrow symbol, etc., the history range indicator may refer to a position on the occlusion pressure display graphic 512-1 corresponding to the minimum history value and the maximum history value, and may also be used in conjunction with a numerical display of the minimum history value of the pressure parameter during the previous time period, and a numerical display of the maximum history value of the pressure parameter during the previous time period.

In particular, many occlusion alarms are clinically triggered due to an improper setting of the occlusion pressure threshold, which if blindly modified by the operator may cause the occlusion pressure alarm to be frequently triggered again or fail to effectively monitor the actual occlusion of the infusion environment.

And by setting the historical range indicator to indicate the minimum and maximum historical values of the pressure parameter during the previous time period, the associated system of the infusion pump 100 may be facilitated to either timely give a suggested set point for the occlusion pressure threshold or the operator may be facilitated to adjust the occlusion pressure threshold deemed appropriate based on the minimum and maximum historical values of the pressure parameter. In addition, if the correlation system triggers an occlusion alarm, the correlation system can also self-learn based on the minimum and maximum historical values to provide an appropriate occlusion pressure threshold.

The history range indicator of the above embodiments is provided in the occlusion pressure display graphic 512-1, and in some embodiments, the display controller 140 is configured to output the occlusion pressure display graphic 512-1 to the touch screen. The processor 150 is further configured to detect a trigger event based on blocking an area of the pressure display graphic 512-1, triggering the display module to generate a pressure trend display graphic 512-2 as shown in fig. 10. The pressure trend display graphic 512-2 includes: a numerical display of a minimum historical value of the pressure parameter during a previous time period, and a numerical display of a maximum historical value of the pressure parameter during the previous time period; or, a historical range indicator indicating a minimum historical value and a maximum historical value of the pressure parameter during a previous time period. That is, after the area of the blocking pressure display graph 512-1 on the touch screen receives the trigger event based on the touch sense and/or the contact of the operator, the display module generates the pressure trend display graph 512-2 again, and the pressure trend display graph 512-2 may have only the numerical value display of the minimum historical value and the numerical value display of the maximum historical value, or only the historical range indicator, or may have the numerical value display of the minimum historical value, the numerical value display of the maximum historical value and the historical range indicator at the same time.

Since the display area of the occlusion pressure display graph 512-1 is relatively small due to the number of images to be presented simultaneously in the display panel 502, when the historical range indicator is also set in the occlusion pressure display graph 512-1, the historical range indicator and the setting sizes of various values and marks in the occlusion pressure display graph 512-1 may be relatively small and inconvenient for the operator to view, and therefore, setting a pressure trend display graph 512-2 alone may not only avoid the various values and marks in the occlusion pressure display graph 512-1 from being too small, but also facilitate the operator to view the variation trend of the pressure parameter.

In some embodiments, the processor 150 may be further configured to detect a triggering event based on the area of the pressure trend display graphic 512-2, toggling the pressure trend display graphic 512-2 during another previous time period. That is, after the region of the currently displayed pressure trend display graphic 512-2 on the touch screen receives an operator tactile and/or contact based triggering event, it may switch to another pressure trend display graphic 512-2 earlier than the currently displayed pressure trend display graphic 512-2 to facilitate the operator to view or compare the pressure trend trends during different time periods.

Further, as shown in FIG. 10, the pressure trend display graph 512-2 further includes a numerical display 512-1d of the occlusion pressure threshold value or a fifth visual indicator 512-2b corresponding to the occlusion pressure threshold value, i.e., the pressure trend display graph 512-2 may only set the numerical display 512-1d of the occlusion pressure threshold value, may only set the fifth visual indicator 512-2b corresponding to the occlusion pressure threshold value, and may also set the numerical display 512-1d of the occlusion pressure threshold value and the fifth visual indicator 512-2b corresponding to the occlusion pressure threshold value simultaneously, e.g., 525, 700, and 900 in FIG. 10 are several different numerical displays 512-1d of the occlusion pressure threshold values, and the operator may adjust the current occlusion pressure threshold value to any one of 525, 700, and 900, and the fifth visual indicator 512-2b is 525, 700, and 900, respectively, 700 and 900.

The setting of the numerical display 512-1d of the occlusion pressure threshold or the fifth visual identifier 512-2b corresponding to the occlusion pressure threshold may facilitate the operator to view the corresponding relationship between the historical range indicator and the currently set occlusion pressure threshold, so as to facilitate the operator to determine whether the size of the occlusion pressure threshold needs to be adjusted, for example, if the maximum historical value of the pressure parameter during the previous time period indicated by the historical range indicator is far smaller than the currently set occlusion pressure threshold, it indicates that the currently set occlusion pressure threshold may be too large, the real-time pressure monitoring system may not trigger an occlusion alarm, the monitoring effect of the real-time pressure monitoring system is not good, and the operator may be required to decrease the currently set occlusion pressure threshold; however, if the minimum historical value of the pressure parameter during the previous time period indicated by the historical range indicator is closer to the currently set occlusion pressure threshold, indicating that the currently set occlusion pressure threshold may be smaller, the real-time pressure monitoring system may trigger an occlusion alarm, and may require the operator to increase the currently set occlusion pressure threshold.

It is to be understood that 525, 700, and 900 are exemplary only and are intended to represent several adjustable occlusion pressure thresholds, and that the particular adjustable occlusion pressure threshold is not limited to several values of 525, 700, and 900, which may be set as desired. In other embodiments, different blocking pressure thresholds may also be represented by gear symbols, such as P1, P2, P3, and the like.

In some embodiments, the pressure trend display graphic 512-2 may further include a numerical display 512-1b of the most recently detected pressure parameter and a sixth visual indicator corresponding to the most recently detected pressure parameter to facilitate the user in comparing the most recently detected pressure parameter to a minimum historical value and a maximum historical value of the pressure parameter.

In some embodiments, as shown in FIG. 10, the pressure trend display graphic 512-2 further includes: at least one intermediate historical value of the pressure parameter. The intermediate, maximum and minimum history values form a pressure trend cue line 512-2 a. The pressure trend indicating line 512-2a can more intuitively display the historical trend of the pressure parameter, for example, if the pressure trend indicating line 512-2a is far away from the currently set occlusion pressure threshold value all the time or for a long time, it indicates that the currently set occlusion pressure threshold value may be too large, the real-time pressure monitoring system is difficult to trigger an occlusion alarm, the monitoring effect of the real-time pressure monitoring system is not good enough, and an operator may be required to turn down the currently set occlusion pressure threshold value; if the pressure trend indicative line 512-2a is at or near the currently set occlusion pressure threshold for a long period of time, it indicates that the chance of triggering an occlusion alarm is high, possibly requiring the operator to adjust the currently set occlusion pressure threshold upward.

In some embodiments, as shown in fig. 10, the pressure trend display graph 512-2 may further include a plurality of numerical displays representing safe pressures and a seventh visual indicator 512-2c corresponding to the numerical displays of the safe pressures, for example, 50, 225 and 375 in fig. 10 are all numerical displays of the safe pressures, and the dashed lines corresponding to the right of 50, 225 and 375 are all the seventh visual indicators 512-2 c.

In some embodiments, the fifth visual indicator 512-2b and the seventh visual indicator 512-2c may be represented by different colors, for example, the fifth visual indicator 512-2b may be red, and the seventh visual indicator 512-2c may be green, or the blocking pressure threshold value with a relatively small value, for example, the fifth visual indicator 512-2b corresponding to 525 and 700 in the above embodiments may be yellow, and the blocking pressure threshold value with a relatively large value, for example, the fifth visual indicator 512-2b corresponding to 900 in the above embodiments may be red, and the seventh visual indicator 512-2c may still be green, so that the operator can more visually check the variation trend of the pressure parameter.

The processor 150 of the infusion pump 100 of the above embodiment is further configured to control the display module to adjust the occlusion pressure display graph 512-1 during the operation of the driving mechanism 214, so that the value display 512-1b of the latest detected pressure parameter in the occlusion pressure display graph 512-1 is changed synchronously with the first visual identifier 512-1c corresponding to the latest detected pressure parameter, which is equivalent to that the first visual identifier 512-1c can be dynamically changed correspondingly with the change of the latest detected pressure parameter during the operation of the driving mechanism 214.

In some embodiments, the first visual indicia, the second visual indicia, and the third visual indicia are shape symbols, the method further comprising: and in the working process of the driving mechanism, adjusting the blocking pressure display graph to enable the first visual mark, the second visual mark and the third visual mark in the blocking pressure display graph to respectively change between a separation state and an overlapping state relative to the projection position or the projection area of the graph carrier.

By configuring the first visual indicator 512-1c, the second visual indicator 512-1e, and the third visual indicator 512-1f to change between the separated state and the overlapped state with respect to the projection position or the projection area of the graphic carrier 512-1a, respectively, it is possible to facilitate the operator to intuitively understand which pressure range the newly detected pressure parameter is in, so as to facilitate the operator to take corresponding countermeasures.

and S616, driving the driving mechanism to stop working, and adjusting the blocking pressure display graph, so that the projection position or the projection area of the first visual mark on the graph carrier is overlapped with the projection position or the projection area of the second visual mark on the graph carrier or the sequence of the first visual mark and the second visual mark is changed in the adjusted blocking pressure display graph.

That is, for the infusion pump 100 of the above embodiment, the occlusion pressure display graph 512-1 at this time visually displays that the value of the newly detected pressure parameter has exceeded the value of the occlusion pressure threshold, so that the operator can timely know the reason why the driving mechanism 214 stops working.

and S624, detecting a trigger event based on the edit item of one of the occlusion pressure thresholds, and updating the numerical display of the occlusion pressure threshold in the occlusion pressure display graph according to the selected numerical value of the occlusion pressure threshold or the gear of the occlusion pressure threshold.

That is, with the infusion pump 100 of the above embodiment, instead of the occlusion pressure display graphic 512-1 displaying the value of the newly detected pressure parameter having exceeded the value of the occlusion pressure threshold, the occlusion alarm interface 512-3 may be displayed directly when the value of the newly detected pressure parameter exceeds the value of the occlusion pressure threshold. The related blockage alarm information can be directly displayed to an operator through the blockage alarm interface 512-3, and the operator can also adjust the current blockage pressure threshold through the quick inlet 512-3a for setting the blockage pressure threshold on the blockage alarm interface 512-3, so that the convenience of handling the blockage alarm by the operator can be improved.

In some embodiments, the occlusion pressure recommendation threshold may be determined according to historical pressure values of a past preset time period, for example, may be a concentration interval of the historical pressure values within the past 1 day, so as to determine a pressure threshold closest to the concentration interval as the occlusion pressure recommendation threshold, thereby making the occlusion pressure threshold more accurate. In some embodiments, the recommended occlusion pressure threshold may be related to the type of drug being infused, for example, a concentration interval of historical pressure values for a particular drug being infused over the past 1 month may be determined such that the closest pressure threshold to the concentration interval is the recommended occlusion pressure threshold.
