In order to reduce the disadvantage of low accuracy of the respiration rate measurement caused by the medical staff needing to pay attention to the timing while observing the thoracic fluctuation of the subject, in the embodiment of the present application, the monitoring device 30 (shown in fig. 3) can automatically perform the timing and calculate the respiration rate of the subject based on the respiration frequency of the subject determined by the user, thereby reducing the influence of the accuracy of the respiration rate measurement caused by manual timing or paying attention to whether the preset time duration is reached at any time during the measurement process. The monitoring device 30 includes, but is not limited to, a multi-parameter monitor or module assembly 10 (shown in fig. 1), a bedside monitor 212 (shown in fig. 10), a portable monitoring device 213 (shown in fig. 10), and other devices with vital sign measurement functions.

Referring to FIG. 1, a block diagram of hardware components of a multi-parameter monitor or module according to an embodiment of the present application is shown.

The parameter measurement circuit 112 may include one or more physiological parameter measurement circuits, and the parameter measurement circuit 112 may be, but is not limited to, a physiological parameter measurement circuit (module), a human physiological parameter measurement circuit (module) or a sensor for acquiring a human physiological parameter, and the like. The parameter measurement circuit 112 obtains the physiological sampling signal related to the testee obtained by the external physiological parameter sensor accessory through the expansion interface, and obtains the physiological data after processing for alarming and displaying. The expansion interface can also be used for outputting a control signal which is output by the main control circuit 113 and is about how to acquire the physiological parameter to an external physiological parameter monitoring accessory through a corresponding interface, so as to realize monitoring control on the physiological parameter of the testee.

Of course, the main control circuit 113 may further include at least one of the power management module 105, the power IP module, the interface conversion circuit, and the like. The power management module 105 is used to control the power on/off of the whole device, the power-on timing sequence of each power domain inside the board, the charging and discharging of the battery, and the like. The power supply IP block refers to a power supply module that associates a schematic diagram of a power supply circuit unit frequently called repeatedly with a PCB layout and solidifies the schematic diagram into individual power supply modules, that is, converts an input voltage into an output voltage through a predetermined circuit, wherein the input voltage and the output voltage are different. For example, a voltage of 15V is converted into 1.8V, 3.3V, 3.8V, or the like. The power supply IP module can be single-path or multi-path. When the power supply IP block is single-pass, the power supply IP block may convert an input voltage into an output voltage. When the power IP module is the multichannel, the power IP module can be a plurality of output voltage with an input voltage conversion, and a plurality of output voltage's magnitude of voltage can be the same, also can not be the same to can satisfy a plurality of electronic component's different voltage demands simultaneously, and the module is few to the external interface, and the work is black box and external hardware system decoupling zero in the system, has improved whole electrical power generating system's reliability. The interface conversion circuit is used for converting signals output by the minimum system main control module (i.e. at least one processor and at least one memory in the main control circuit) into input standard signals required to be received by actual external equipment, for example, supporting an external VGA display function, converting RGB digital signals output by the main control CPU into VGA analog signals, supporting an external network function, and converting RMII signals into standard network differential signals.

The processor 101 may determine the pulse rate of the subject based on the pulse wave signal obtained by the blood oxygen parameter measuring circuit. For example, the processor 101 may obtain a waveform diagram included in the Pulse wave signal based on the time domain feature analysis, and may determine a Pulse Rate (PR) of the subject according to the number N of Pulse periods of the Pulse wave included in the time of t seconds.

In addition, the multi-parameter monitor or module assembly 10 may further include one or more of a display screen 114, an alarm circuit 116, an input interface circuit 117, and an external communication and power interface 115. The main control circuit 113 is used to coordinate and control the boards, circuits and devices in the multi-parameter monitor or module assembly 10. In this embodiment, the main control circuit 113 is used to control data interaction between the parameter measuring circuit 112 and the communication interface circuit and transmission of control signals, and transmit physiological data to the display screen 114 for display, or receive user control instructions input from the display screen or physical input interface circuits such as a keyboard and a key, and also output control signals on how to acquire physiological parameters.

The main control circuit completes the calculation of the physiological parameters and can send the calculation results and the waveforms of the parameters to a host (such as a host with a display screen, a PC, a central station and the like) through the external communication and power interface 115. The external communication and power interface 115 may be one or a combination of an Ethernet (Ethernet), a Token Ring (Token Ring), a Token Bus (Token Bus), and a local area network interface (lan interface) formed by a backbone Fiber Distribution Data Interface (FDDI) as the three networks, one or a combination of wireless interfaces such as infrared, bluetooth, wifi, WMTS communication, or one or a combination of wired data connection interfaces such as RS232 and USB.

In one embodiment, the multi-parameter monitor or module assembly 10 can be disposed outside the monitor housing as an independent external parameter-plug module, which can be a plug-in monitor formed by a host computer (including a main control board) plugged into the monitor as a part of the monitor, or can be connected to the host computer (including the main control board) of the monitor via a cable, and the external parameter-plug module can be an external accessory of the monitor. Of course, the parameter processing can also be arranged in the shell and integrated with the main control module, or physically separated and arranged in the shell to form the integrated monitor.

Referring to fig. 2, a flowchart illustrating steps of a vital sign measurement method according to an embodiment of the present application is shown. The vital sign measuring method comprises the following steps:

step 100, a breath measurement starting instruction input by a user through a display screen is detected.

Referring to fig. 3, a block diagram of a hardware structure of a monitoring device according to an embodiment of the present application is shown. The monitoring device 50 includes a processor 300, a memory 302, a display 304, a sound acquisition device 306, an image acquisition device 308, a physical count button 310, and computer programs (instructions) stored in the memory 302 and executable on the processor 300. The processor 300 may exchange data with the memory 302, the display 304, the sound capture device 306, the image capture device 308, and the physical keys 310 via the bus 312. The display screen 304 has a touch device for receiving an input operation by a user through the touch device.

In this embodiment, the processor 300 may control the display screen 304 to display a plurality of display interfaces including, but not limited to, a start-up interface, a self-test interface, a vital signs display interface 500 (shown in fig. 4), and the like. For example, when a power-on key of the monitoring device 30 is pressed, the processor 300 controls the display screen 304 to display a start-up interface. During the start-up process, the monitoring device 30 can perform a self-test operation, and the processor 300 controls the display screen 304 to display a self-test interface.

Please refer to fig. 4, which is a schematic diagram of a vital sign display interface according to an embodiment of the present application. After the monitoring device 30 has completed booting, a vital signs display interface 500 may be displayed on the display screen 304. In this embodiment, when the vital sign display interface 500 is displayed, it indicates that the monitoring device 30 is in the state of the vital sign display interface, and at this time, the vital sign display interface 500 may be used to display different types of parameter information, so that the user may obtain different types of parameter information obtained by measuring the subject.

In this embodiment, the vital signs display interface 500 can include a plurality of vital signs data item regions. For example, vital signs data item regions within the vital signs display interface 500 include, but are not limited to, a blood pressure display region 510, a pulse analysis display region 520, a body temperature display region 540, and a respiratory measurement data item region 530. The blood pressure display area 510 can display the information of the diastolic blood pressure and the systolic blood pressure of the subject obtained by the non-invasive blood pressure or invasive blood pressure measurement mode of the sensor attachment 111; the body temperature respiration display area 540 is used for displaying information on the body temperature (e.g., the temperature in degrees fahrenheit) of the subject. The pulse analysis display area 520 includes a pulse rate display section 526 for displaying pulse rate information, a blood oxygen information display section 523 for displaying blood oxygen content, and a waveform display section 522 for displaying a waveform diagram of a pulse. Specifically, as shown in fig. 4, the respective vital sign data item regions respectively show that the measurement parameter of the non-invasive blood pressure NIBP is 120/80(mmHg), the measurement parameter of the blood oxygen SPO2 is 98 (%), the measurement parameter of the pulse is 64(bpm), and the measurement parameter of the body temperature is 102.5 (F).

The respiratory measurement data item area 530 includes a timing setting section 532 and a parameter display section 534. In this embodiment, the timing setting partition 532 is used to display a start icon, such as a virtual key "Timer", and when the start icon is clicked, the processor 300 detects a respiratory measurement start instruction input by the user through the display screen 304. If the user clicks the display area where the start icon is located, the processor 300 receives a gesture operation input by the user in the display area where the start icon is located, and thus may determine that a respiratory measurement start instruction is received.

In an embodiment, when the display screen 304 displays the vital sign display interface 500, if the user clicks on other display areas (such as the blood pressure display area 510, the pulse analysis display area 520, and the body temperature display area 540) of the display screen 304, the processor 300 may also detect that the user inputs a respiratory measurement starting instruction through the display screen 304. Alternatively, in the state where the vital signs display interface 500 is displayed, when a gesture operation first input by the user is performed in a part or all of the area of the display screen 304, the processor 300 may determine that a respiratory measurement start instruction input by the user through the display screen 304 has been detected.

And 102, executing timing operation according to the starting instruction.

In this embodiment, in order to reduce the need for the medical staff or the user to pay attention to the timing while observing the thoracic fluctuation of the subject, the monitoring device 30 may perform the timing operation after detecting the respiratory measurement start instruction, so that the user may not need to pay attention to the timing operation while observing the thoracic fluctuation of the subject.

When measuring the respiratory rate of the subject, the processor 300 further needs to determine a preset time duration to calculate the respiratory rate of the subject according to the determined preset time duration and the respiratory frequency. In one embodiment, the predetermined time period may be manually entered and determined by the user without the user having to pay attention to the timing during the measurement. That is, in one measurement process, if the user manually inputs the preset time length, the preset time length may be fixed in the measurement process. In an embodiment, the preset duration may be dynamically determined by the processor 300 based on the gesture operation of the user.

Fig. 5 is a schematic view of an interface when a user sets a preset time duration on a vital sign display interface according to an embodiment of the present application. In this embodiment, the preset duration may be manually input and determined by the user. When the start instruction is detected, the processor 300 controls the display screen 304 to display the duration setting interface 536, and at this time, the user can set a preset duration corresponding to the design time in the duration setting interface 536, such as 20, 30, 50 seconds, and the like. Duration setting interface 536 includes an input box, number keys, delete keys, and ok keys. When the user clicks the number button on the duration setting interface 536, the processor 300 controls the input box of the duration setting interface 536 to display the number corresponding to the clicked number button. The processor 300 may also control the parameter display section 534 of the display screen 304 to synchronously display the clicked numeric keys in real time. For example, when the user clicks the number button "2", the processor 300 displays "2" in the input box in the duration setting interface 536, and simultaneously displays the number "2" in the parameter display section 534. The delete key is used to change the number that has been entered, such as by deleting the last entered number in the input box via the delete key.

Fig. 6 is a schematic interface diagram illustrating a vital sign display interface after a user has set a preset duration in accordance with an embodiment of the present application. When the processor 300 receives a user click on the determination key, the processor 300 may take the entered number (including but not limited to 1-digit, 2-digit, and 3-digit numbers) as the preset duration. For example, when the user finishes inputting the number (or character) "20" in the duration setting interface 536, the processor 300 controls the parameter display section 534 to display the number (or character) "20".

In this embodiment, when the user clicks the determination button of the time length setting interface 536, the processor 300 starts to perform the timing operation, and the processor 300 may output a prompt message for starting timing, including but not limited to a sound or a light. When the timing operation has begun to be performed, the processor 300 also refreshes the time-progress of the respiration measurement in real-time on the display screen 304. In one embodiment, after the timing operation begins to be performed, the processor 300 may send a reminder to the user of the time progress of the respiratory measurement in the form of an audible signal. For example, after the timing operation is started, the processor 300 may control the sound emitting device in the alarm circuit to output an alert sound every preset time, such as 5 seconds/10 seconds, so that the user may estimate the measured time based on the total number of times the alert sound is heard when measuring the number of breathings of the subject. For example, if the preset time is 5 seconds, the preset time period is 20 seconds, and at this time, when the user hears the alert tone 4 times, it indicates that the measurement of the breathing rate of the subject is finished, and the user may not need to input any gesture operation or press a key or the like.

Fig. 7 is a schematic interface diagram showing a time progress of a respiration measurement on a vital sign display interface according to an embodiment of the present application. The processor 300 may display the time progress of the corresponding measurement based on the type of the timing operation. The types of timing operations may include count-up and count-down operations. If the type of timing operation is a count-up operation, the time schedule of the respiration measurement that is refreshed in real time by the processor 300 on the display screen 304 is the duration of the time period from the beginning of the timing operation to the current time. For example, when the user clicks a determination key of the time period setting interface 536, the processor 300 may control the parameter display interface 534 to display "0 s" indicating that the time period of the time period from the start of the execution of the time counting operation to the present time is 0, that is, the time counting operation has just started.

Please refer to fig. 8, which is a schematic diagram illustrating a time progress of a measurement according to another embodiment of the present application. If the type of the timing operation is a countdown operation, the time progress of the respiration measurement refreshed in real time by the processor 300 on the display screen 304 is the time remaining in the preset time period at the current moment. For example, when the counting operation starts for 5 seconds, since the preset time period is 20 seconds, the time remaining in the preset time period at the current time is 15 seconds, and thus the processor 300 may control the parameter display interface 534 to display "15 s".

In an embodiment, the processor 300 may also display a switch button 538 such that a user may select to display the measured time progress in a count-up operation or a count-down operation based on the switch button 538. As shown in fig. 8, when the user clicks the switch button 538, it indicates that the user needs to switch the countdown operation mode to the count-up operation mode, and at this time, the time schedule of the respiration measurement refreshed in real time by the processor 300 on the display screen 304 is the time length of the time period from the time when the timing operation is performed to the current time, for example, the control parameter display interface 534 displays "5 s".

And 104, detecting the breathing frequency of the testee input by the user within a preset time length, or detecting the breathing frequency acquired by the external equipment within the preset time length.

In this embodiment, when the user inputs the preset duration through the duration setting interface 536, the processor 300 clocks the preset duration after the timing operation starts, and the processor 300 stops the timing operation after the preset duration is reached to stop the timing. At this time, the processor 300 may output a prompt message indicating the end of the timing, including but not limited to a text, a voice, and the like.

In the process of performing the timing operation, the user may input a corresponding gesture operation in a part or all of the area of the display screen 304, wherein the user inputs a gesture operation in a part or all of the area of the display screen 304 every time the subject completes a complete exhalation or inhalation within a preset time period. For example, when a timing operation is started, the user clicks on a specific area (such as the blood pressure display area 510 or the pulse analysis display area 520 or the body temperature display area 540 or the respiration measurement data item area 530) within the display screen 304 to input the gesture operation; alternatively, the user taps on some or all of the area of display screen 304 to input the gesture operation. Upon clicking on the display 304, the user may touch the display 304 with a finger; when tapping the display screen 304, the user may press the display screen 304 with a certain force or tap the display screen 304 with the knuckle of a finger to input the gesture operation.

In this embodiment, in the state of the vital sign display interface, before the processor 300 receives a respiratory measurement start instruction input by the user, the user may click on the blood pressure display area 510, the pulse analysis display area 520, the body temperature display area 540, or other areas to view the specific information of the corresponding measurement item. For example, when the user can click on the waveform display section 522 of the pulse analysis display area 520 for displaying the waveform diagram of the pulse, the processor 300 can mark the waveform diagram with specific information of the pulse wave of the subject, including but not limited to the variation number, the maximum pulse interval, and the minimum pulse interval of the pulse wave. After the processor 300 receives a user-input respiratory measurement initiation instruction, the monitoring device 30 may enter a respiratory rate measurement mode. In the respiration rate measuring mode, if the user clicks a specific area (such as the blood pressure display area 510 or the pulse analysis display area 520 or the body temperature display area 540 or the respiration measurement data item area 530) in the display screen 304, the processor 300 does not respond to the specific information of the displayed measurement item, but takes the operation of clicking the specific area in the display screen 304 as a gesture operation for inputting the number of breaths of the subject.

The processor 300 records the input times of the gesture operation within the preset time length from the execution of the timing operation, that is, the processor 300 records the input times of the gesture operation within the preset time length until the timing reaches the preset time length. At this time, the processor 300 may use the input number of the gesture operations within the preset time period as the breathing number of the testee.

And 106, calculating and outputting and displaying the breathing rate of the testee within the preset time according to the preset time and the breathing frequency.

When determining the preset time duration a (in seconds) and the number of breaths B, the processor 300 may calculate a breathing rate C of the subject within the preset time duration a, wherein the breathing rate C may be represented as: c-60 × B/a (units per minute), i.e. the number of breaths taken by the subject in 1 minute.

In an embodiment, the user may determine that the preset duration is unreasonable, for example, the preset duration is too long, and at this time, the user may end the timing operation in advance. For example, the user may input the stop timing operation through an end operation key (the end operation key may be a physical key or a virtual key displayed in the display screen 304) provided on the monitoring device 30 to achieve the goal of the early end timing operation. In this way, when the processor 300 detects that the timing operation is stopped by the user, the processor 300 may determine that the preset time duration is the time duration from the starting time of the timing operation to the time period of receiving the timing operation stop, and may determine the breathing rate of the subject according to the number of times of gesture operations received within the time duration from the starting time of the timing operation to the time period of receiving the timing operation stop.

In an embodiment, the preset duration may be dynamically determined by the monitoring device 50 based on the gesture operation of the user. The processor 300 may use a duration of the time period according to the starting time of the timing operation and the current time of the gesture operation input each time as a preset duration. Thus, each time the processor 300 receives a gesture operation, the processor 300 may obtain different preset durations, and the processor 300 may further update the calculated breathing rate in real time based on the different preset durations and the corresponding input times of receiving the gesture operation. For example, the time when the processor 300 starts to perform the timing operation is Ta, the current time corresponding to the time when the nth input gesture operation is received is Tb, at this time, the processor 300 determines that the preset time duration is Ta-Tb, the number of breaths is N, and the processor 300 may calculate a breathing rate C of the subject, where the breathing rate C may be represented as: c60 × N/(Ta-Tb). The processor 300 can also control the parameter display section 534 to display the breathing rate corresponding to each gesture operation in real time.

In an embodiment, the monitoring device 50 can also calculate the breathing rate corresponding to each gesture operation input in real time when the user inputs the preset duration. For example, when the timing operation starts to be performed, the processor 300 may determine a preset time length corresponding to a time length of a current time period of the gesture operation input each time, and determine the total number of the gesture operations input within the timing time length, so as to determine the breathing rate of the subject in real time according to the total number of the gesture operations input and the preset time length. When the monitoring device 50 counts the operation result, the breathing frequency of the subject within the preset time period is calculated to obtain the final breathing rate.

In one embodiment, after setting the predetermined duration through the duration setting interface 536, the user can input the number of breaths of the subject within the predetermined duration by pressing the physical count button 310. For example, the user may press the physical count button 310 once when the subject completes a complete exhalation or inhalation within a preset time period, so that the processor 300 may determine the number of times the physical count button 310 is pressed within the preset time period, and may use the number of times the physical count button 310 is pressed as the number of breaths of the subject within the preset time period. Further, the processor 300 may calculate the respiratory rate of the subject based on the preset time duration and the number of times the physical count button 310 is pressed, and display the calculated respiratory rate through the parameter display partition 534.

In one embodiment, the processor 300 may also dynamically determine the preset time period according to the pressing time of the physical count key 310. For example, the processor 300 may use a duration of a time period of a current time when the physical count key 310 is pressed according to a starting time of the timing operation as a preset duration, so that each time the processor 300 receives a pressing operation when the physical count key 310 is pressed, the processor 300 may obtain different preset durations, and the processor 300 may further update the calculated breathing rate in real time based on the different preset durations and corresponding input times of the received pressing operations. For example, the time when the processor 300 starts to perform the timing operation is Tc, the current time corresponding to the mth press operation is Td, at this time, the processor 300 determines that the preset time period is Td-Td, the respiration frequency is M, and the processor 300 can calculate the respiration rate C of the subject, where the respiration rate C can be represented as: c60 × M/(Td-Tc). The processor 300 can also control the parameter display section 534 to display the respiration rate corresponding to each pressing operation in real time.

In one embodiment, the processor 300 may detect the number of breaths taken by an external device within a preset time period, wherein the external device may be one or more of a pressure sensor, a motion sensor, and a counter. Please refer to fig. 9, which is a schematic diagram of a breath count input interface according to an embodiment of the present application. When the user sets a preset time period through the time period setting interface 536, the processor 300 starts to perform the timing operation, and when the preset time period is reached, the processor 300 stops the timing operation. The processor 300 controls the display 304 to display the breath number input interface 540 after the timing operation is stopped, so that the user can input the breath number acquired by an external device (such as a timer) during the timing operation. The breath number input interface 540 includes an input box, a number button, a delete button, and a confirm button. When the user clicks the number button on the breath number input interface 540, the processor 300 controls the input box of the breath number input interface 540 to display the number corresponding to the clicked number button. The processor 300 may also control the parameter display section 534 of the display screen 304 to synchronously display the clicked numeric keys in real time. For example, when the user clicks the number button "25", the processor 300 displays the number "25" in the input box in the breath number input interface 540 and simultaneously displays the number "25" in the parameter display section 534. The delete key is used to change the number that has been entered, such as by deleting the last entered number in the input box via the delete key. The processor 300 calculates the respiratory rate of the subject based on the respiratory rate input by the respiratory rate input interface 540 and the preset time length. Processor 300 may also control parameter display section 534 to display the calculated breathing rate. In one embodiment, the processor 300 may obtain the number of breaths of the subject within the preset time period from the pressure sensor and the motion sensor, and calculate the breathing rate of the subject. In one embodiment, after the processor 300 receives a signal from the user to click the trigger of the start icon, the processor 300 may control the display 304 to display an interface (not shown) for the user to select between a mode of manually inputting the number of breaths and a mode of learning the number of breaths from an external device. When the user selects the mode for manually inputting the number of breaths, the processor 300 displays the breath number input interface 540.

In one embodiment, after acquiring the preset time period set by the user, the monitoring device 30 collects the voice signal of the user through the voice collecting device 306 from the time when the timing operation is performed. For example, each time the subject completes a complete exhalation or inhalation, the user may speak a corresponding voice. The processor 300 may collect the total number of times of the voice uttered by the user within the preset time period through the sound collecting device 306, so as to use the obtained total number of times of the voice uttered by the user as the number of breathings of the subject within the preset time period. Thus, the processor 300 can also calculate the respiratory rate of the person to be tested according to the preset time and the total times of the voice uttered by the user within the preset time. The sound collection device 306 may be a microphone or other component that can capture sound signals.

In an embodiment, after acquiring the preset duration set by the user, the monitoring device 30 acquires, by the image acquisition device 308, a gesture operation performed by the user to record the number of breaths of the subject from the time when the timing operation is performed. For example, each time the subject completes a complete exhalation or inhalation, the user may make a corresponding gesture. The processor 300 may obtain image information corresponding to each gesture operation through the image acquisition device 308, and determine the total number of times of gesture operations performed by the user within the preset time length based on the image information, and use the total number of times of gesture operations as the number of breathings of the testee within the preset time length. In an embodiment, the memory 302 stores image information based on standard gesture operation, and the processor 300 may identify the obtained image information to determine whether the obtained image information contains the standard gesture operation. When the resulting image contains a standard gesture operation, the processor 300 increases the number of breaths of the subject by 1. Thus, the processor 300 can also calculate the respiratory rate of the subject according to the preset duration and the total number of gesture operations performed within the preset duration. The image capturing Device 308 may be a CCD (Charge Coupled Device), a CMOS (Complementary Metal-Oxide Semiconductor), or other image sensor.

In an embodiment, the Processor 300 may be a Central Processing Unit (CPU), other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, a discrete Gate or transistor logic device, a discrete hardware component, or the like. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, such as a microprocessor. In an embodiment, the processor 300 may comprise a timing unit for performing timing operations, i.e. the timing operations may be timed by the processor 300. In one embodiment, the monitoring device 30 can further include a timing circuit, such that when the processor 300 receives the breath measurement start command, the processor 300 can control the timing circuit to perform a timing operation, and control the timing circuit to stop the timing operation after detecting that the preset time period is reached.

The storage device 302 can be used to store the computer programs and/or modules, and the processor 300 implements the various functions of the vital sign measurement method by running or executing the computer programs and/or modules stored in the storage device 302 and invoking data stored in the storage device 302.

The processor 300 runs a program corresponding to the executable program code stored in the storage device 302 by reading the executable program code for performing the vital sign measurement method in any of the previous embodiments.

According to the vital sign measuring method, the timing operation is executed after the respiration measurement starting instruction is received, so that the time is automatically timed, the respiration frequency of the testee in the preset time is obtained, and then the respiration frequency is determined according to the preset time and the respiration frequency, and the defect that the accuracy of the respiration rate measurement is not high due to the fact that medical staff need to pay attention to the timing while observing the thoracic fluctuation of the testee is favorably reduced. In addition, the time length corresponding to the timing operation is set by the user or automatically determined based on the gesture operation of the user, so that the user can conveniently select the time length according to the use habit of the user, and the operability of the system is improved.
