All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 2, fig. 2 is a block diagram illustrating a method for controlling a ventricular assist device according to an embodiment of the present disclosure, which can be applied to the ventricular assist system shown in fig. 1. As shown in fig. 2, the method comprises the steps of:
in step 202, it is checked whether the first device is connected to the ventricular assist device.
As shown in fig. 3, the first device is an external device for controlling a ventricular assist device. The system comprises an OLED screen, a watchdog MCU and a memory, wherein the watchdog MCU is used for detecting whether the first equipment normally operates or not, and controlling a loudspeaker to send out an alarm sound if a correct dog feeding signal is not received within a preset time (such as 1 second); the memory is used for recording and storing alarm information, storing data information when the ventricular assist device runs for a long time or a short time and storing and memorizing patient information. The OLED screen is used for displaying alarms, ventricular assist device data (such as rotating speed, power, flow, pulse, time and the like), equipment SN, software version information and the like. Meanwhile, the first equipment is also used for detecting whether a fault occurs or not in real time, and when the fault occurs, the alarm is sent out through the indicating lamp and the loudspeaker.
The first device can judge whether the ventricular assist device is connected with the first device through the watchdog MCU, or the first device can detect an interface, connected with the ventricular assist device, of the first device in real time, and determine whether the first device is connected with the ventricular assist device by reading state information of the interface.
For example, the first device may generate an alert message to alert when the first device is not connected to the ventricular assist device. The first equipment can send out an alarm according to the alarm information indicator lamp and the loudspeaker, and also can carry information disconnected with the ventricular assist device in the alarm information and send the information to the second equipment, and the second equipment displays the information and gives an alarm; or receiving an inquiry request sent by the second equipment, sending alarm information carrying information of disconnection with the ventricular assist device to the second equipment, and giving an alarm by the second equipment.
Step 204, when the first device is connected with the ventricular assist device, a target operation state and a target operation mode are obtained, wherein the target operation mode is a current operation mode of the first device, and the target operation state is a current operation state of the ventricular assist device.
The target operation mode of the first device is used for determining the use environment corresponding to the target operation state of the ventricular assist device. The use scene of the ventricular assist device is set through the target working mode, and then the starting and stopping operations of the ventricular assist device by a user are limited, so that the life safety of a patient is guaranteed. Especially for implantable ventricular assist devices, the stopping and operation of the ventricular assist device is critical to the life safety of the patient, i.e. it is crucial to limit the starting and stopping of the ventricular assist device for the usage scenario of the ventricular assist device.
In an embodiment of the application, when the first device detects that the first device is connected to the ventricular assist device, a current operating mode of the first device may be obtained, and a control strategy for the ventricular assist device may be determined according to the current operating mode. The target working mode of the first device may be continued to the working mode of the last operation, or the working mode of the first device may be set based on an operation instruction of a user. After the target working mode is obtained, the first device can also judge the target running state of the ventricular assist device according to the running data sent by the received ventricular assist device, so that the accurate control on the ventricular assist device is realized according to the target running state in the target working mode, and the safety of a user is improved.
In one embodiment, the method further comprises: and if receiving a switching command from the second equipment, switching the target working state to an operation mode or a normal mode according to the switching command.
The mode switching instruction may be an operation instruction generated by the second device according to a user operation. Specifically, when the user sets the working mode of the first device through a key or touch mode, the second device may generate a corresponding mode switching instruction according to the operation of the user, and send the mode switching instruction to the first device. After receiving the mode switching instruction, the first device can switch the working mode of the first device according to the mode switching instruction, and the execution condition corresponding to the first device is limited through the working mode, so that the condition caused by misoperation of a user is avoided. For example, in order to avoid that the operation is affected by the ventricular assist device being started due to misoperation of the second device in the operation process, the working mode of the controller can be switched to the operation mode by sending a mode switching instruction before the operation; after the operation is finished, in order to avoid the ventricular assist device from stopping running due to misoperation of the second device, the working mode of the controller can be switched to the normal mode by sending a mode switching instruction after the operation is finished, so that the life safety of the patient is improved.
In one embodiment, the method further comprises: if the target working mode is the operation mode and the first duration is longer than the preset duration, the target working mode is switched to the normal mode, and the first time is the duration of disconnection between the first equipment and the second equipment.
Different from the mode switching instruction which is received, when the working mode is the operation mode and the disconnection duration time of the first equipment and the second equipment exceeds the disconnection first time, in order to ensure the safety of a patient, the first equipment can directly switch the working mode of the first equipment from the operation mode to the normal mode, so that the first equipment is convenient for the patient to use, and the life safety of the patient is guaranteed. For example: after one operation is finished, the first device and the second device are disconnected, mode switching is not needed by a user, and the user can be guaranteed to be concentrated on affairs related to the operation; and the ventricular assist device in the patient's body can be automatically switched to the normal mode in order to alleviate or solve the problems of heart failure and the like of the patient.
In the present application, to ensure the safety of the patient in different situations, the working mode of the first device may be divided into an operation mode and a normal mode. In the normal mode, in order to prevent the ventricular assist device from being stopped accidentally due to misoperation to influence the safety of a patient, the first device cannot control the ventricular assist device to stop running and can automatically start the ventricular assist device when the ventricular assist device is stopped accidentally. In the operation mode, in order to prevent the ventricular assist device from being started to operate accidentally due to misoperation, the first device cannot control the ventricular assist device to be started automatically, and only the second device can send a starting command to start the ventricular assist device.
And step 206, if the target working mode is the normal mode, controlling the starting of the ventricular assist device according to the target running state.
The normal mode is a working mode used by the patient in most non-surgical scenarios to alleviate or solve problems such as heart failure in the patient. The operation state of the center chamber auxiliary device may include a normal state, a stop state, and a fault state; the normal state is a state in which the ventricular assist device is in normal operation, the stop state is a state in which the ventricular assist device stops operation after receiving a stop command, and the fault state is a state in which the ventricular assist device stops operation due to a fault.
In the normal mode, when the operating state of the ventricular assist device is detected to be a fault state or a stop state, in order to guarantee the safety of a user, the first equipment can automatically start the ventricular assist device to operate so that the ventricular assist device can normally operate; when the operating state of the ventricular assist device is detected to be a normal state, the relevant ability of the ventricular assist device to receive the operating instruction and stop operating is limited, so that the life safety of a patient is prevented from being endangered due to misoperation.
For example, the ventricular assist device may send instructions to the first apparatus that the ventricular assist device is functioning properly according to a preset cycle; when the first equipment can receive the instruction sent in the preset period, the ventricular assist device operates normally; when the first device cannot receive the instruction sent by the preset period, the operation of the ventricular assist device is stopped.
For example, the first device receives daily operating data collected by the ventricular assist device in real time, analyzes the daily operating data, and considers that the ventricular assist device is a normal device when each operating data is within the data range to which the data type belongs. And if the daily operation data has data abnormality or data loss, the ventricular assist device is considered to be in a fault state. If the first device does not receive the daily operation data of the ventricular assist device or the daily operation data is a value corresponding to the stopped state, the ventricular assist device is considered to be in the stopped state.
In one embodiment, detecting an operating state of the ventricular assist device and controlling activation of the ventricular assist device based on the target operating state if the target operating mode is the normal mode comprises: when the target operation state is a fault state, acquiring a first starting frequency, wherein the first starting frequency is the frequency of the first device for automatically starting the ventricular assist device; if the first starting times are less than or equal to a first threshold value, starting the ventricular assist device, and determining that the target running state is a normal state; and if the first starting times are larger than the first threshold value, sending first information to the second equipment, wherein the first information is used for indicating that the ventricular assist device has operation failure.
The first device self-starting ventricular assist device is used for sending a ventricular assist device starting command to control the ventricular assist device to restart through the sent command when the ventricular assist device is not operated due to unexpected stop or user error. The first starting frequency is the frequency of the first device for self-starting the ventricular assist device, the second starting frequency is the frequency of the ventricular assist device for self-starting, and the mechanisms of the first device for self-starting the ventricular assist device and the ventricular assist device for self-starting are independent. For example, the ventricular assist device may be attempting to restart itself during the process of the first device sending the start command to start the ventricular assist device, which is not limited by the embodiment of the present application.
Specifically, when the first device is in the normal mode, the first device may detect whether the ventricular assist device malfunctions in real time during operation thereof. The first device may obtain a first number of activations of the first device self-activating the ventricular assist device when it is detected that a serious failure of the ventricular assist device causes the ventricular assist device to cease functioning. If the first starting frequency is less than or equal to a preset first threshold, the first equipment sends a starting instruction to the ventricular assist device to start the ventricular assist device, adds 1 to the first starting frequency, then detects the running state of the ventricular assist device, determines the target running state as a normal state if the running state of the ventricular assist device is a normal state, and if the running state of the ventricular assist device is still a fault state, the first equipment sends the starting instruction to the ventricular assist device again until the first starting frequency is greater than the first threshold; if the first starting frequency is greater than a preset first threshold, the ventricular assist device is serious in fault and cannot be recovered to normal operation through self-starting, the first equipment can send first information to the second equipment, and the first information can carry indication information that the ventricular assist device is in a fault state, so that the second equipment gives an alarm after receiving the first information. Or when the first starting times are larger than the first threshold value, the first device can alarm directly through the indicator lamp and the loudspeaker.
For example: determining that the target working mode of the first equipment is in a normal mode and the target running state of the ventricular assist device is in a fault state; the first equipment acquires a first starting time m, and if the first starting time m < =5, a self-starting instruction is sent to the ventricular assist device to self-start the ventricular assist device; and if the first starting times m >5, sending the first information to the second equipment.
It should be noted that the first threshold and the second threshold related in the embodiment of the present application may be equal or unequal, and the first threshold and the second threshold may be set by a user, such as 3, 5, 6, 8, 10, and the like, which is not limited in the embodiment of the present application.
In another example, if the target operating mode is a normal mode, controlling activation of the ventricular assist device based on the target operating state includes: when the target operation state is a fault state, acquiring a second starting frequency, wherein the second starting frequency is the self-starting frequency of the ventricular assist device; when the second starting times is larger than a second threshold value, acquiring first starting times, if the first starting times is smaller than or equal to the first threshold value, starting the ventricular assist device, and really ensuring that the target running state is a normal state, otherwise, sending first information to the second equipment; when the second starting frequency is less than or equal to the second threshold, adding 1 to the second starting frequency, detecting whether the ventricular assist device is in the fault state, and if the ventricular assist device is in the fault state, repeating the steps; otherwise, determining the target running state as the normal state.
Ventricular assist device self-activation is the process by which a ventricular assist device self-activates in the context of a fault condition. The first apparatus may detect a target operating state of the ventricular assist device in real-time. When the first device detects that the target operation state of the ventricular assist device is changed into the fault state, the first device can acquire the second starting times and start the ventricular assist device through the ventricular assist device self-starting mechanism. And after the ventricular assist device fails to start, acquiring a second starting time to send a starting instruction through the first equipment to start the ventricular assist device.
In particular, when the first device is in the normal mode, the first device may detect whether it is malfunctioning in real time during operation of the ventricular assist device. The first apparatus may obtain a second number of activations of the ventricular assist device to self-activate when it is detected that the ventricular assist device has failed severely causing it to cease functioning. If the second starting frequency is larger than a preset second threshold, the ventricular assist device is failed to be started automatically, and the first equipment acquires the first starting frequency of the first equipment for starting the ventricular assist device automatically. If the first starting frequency is less than or equal to a preset first threshold, the first equipment sends a starting instruction to the ventricular assist device to start the ventricular assist device, adds 1 to the first starting frequency, then detects the running state of the ventricular assist device, determines the target running state as a normal state if the running state of the ventricular assist device is a normal state, and if the running state of the ventricular assist device is still a fault state, the first equipment sends the starting instruction to the ventricular assist device again until the first starting frequency is greater than the first threshold; if the first starting frequency is greater than a preset first threshold, the failure of the ventricular assist device is serious, and normal operation cannot be recovered through self-starting, the first device can send first information to the second device, and the first information can carry indication information that the ventricular assist device is in a failure state, so that the second device gives an alarm after receiving the first information. Or when the first starting times are larger than the first threshold value, the first device can alarm directly through the indicator lamp and the loudspeaker.
Further, if the second starting frequency is less than or equal to a second threshold, it indicates that the ventricular assist device can be started by itself, so the first device adds 1 to the second starting frequency, then detects the operating state of the ventricular assist device, if the operating state of the ventricular assist device is a normal state, determines the target operating state as a normal state, if the operating state of the ventricular assist device is still a fault state, the first device adds 1 to the second starting frequency, and the ventricular assist device is started by itself again until the second starting frequency is greater than the second threshold.
And the first equipment acquires the second starting times along with the restart of the ventricular assist device in the normal mode, and compares the second starting times with a second threshold value to obtain a second starting times comparison result in the normal mode.
For example: acquiring a second starting frequency n; if the second starting number n < =5, the ventricular assist device can be started automatically, the first device enables the second starting number n to be added with 1, detects whether the ventricular assist device is in a normal state or not, and if the ventricular assist device is still in a fault state, continues to enable n to be added with 1; if n >5, it indicates that the ventricular assist device has failed to self-start, and the first device acquires the first start number m to start the ventricular assist device. If the first starting times m < =5, sending a self-starting instruction to the ventricular assist device to self-start the ventricular assist device; and if the first starting times m >5, sending the first information to the second equipment.
The first device self-starting ventricular assist device and the ventricular assist device self-starting are two independent control modes, and the two control modes respectively change the failure state of the ventricular assist device based on different scenes. Specifically, the first device sends a ventricular assist device starting instruction, and mainly considers the situation that the ventricular assist device is in a failure state; and the self-restarting of the ventricular assist device mainly considers the situation of the failed starting of the ventricular assist device. During the first device self-starting the ventricular assist device, the ventricular assist device self-starting process can occur synchronously, in the hope of solving the problems of both scenarios simultaneously.
And step 208, if the target working mode is the operation mode, controlling the start or stop of the ventricular assist device according to the target running state and the target operation instruction, wherein the target instruction is the operation instruction received from the second equipment.
The operation mode is a working mode used by a patient in an operation scene, and is used for avoiding the problem of increased operation difficulty caused by the starting of a ventricular assist device. Unlike the normal mode, the ventricular assist device in the surgical mode can turn on or off the ventricular control device based on the operation instruction sent by the second device to meet the requirements in the surgical scenario.
Specifically, when the ventricular assist device in the normal mode stops operating, the ventricular assist device is considered to be in a fault state, and the ventricular assist device is automatically started or the first device automatically starts the ventricular assist device, so that the life safety of a patient is guaranteed; after the ventricular assist device in the operation mode stops operating, the ventricular assist device is not started immediately, but waits for an operation instruction, so that the ventricular assist device is prevented from interfering a user to perform an operation on a patient.
In the operation mode, whether the first device has the control function of the ventricular assist device is determined according to the target operation instruction. When the first device receives a target operating instruction that instructs the ventricular assist device to stop operating, the first device does not send an instruction to start the ventricular assist device, and the first device may start the ventricular assist device according to the target operating instruction.
After the target operation instruction indicates that the ventricular assist device is started, the first device can still control the ventricular assist device to stop running based on the new target operation instruction so as to meet the requirements in the operation scene. For example: in a pre-operation stage, the first device controls the ventricular assist device to stop running based on the received operation instruction for operation; at an intra-operative stage, certain emergencies are encountered, and the first device controls the ventricular assist device to start and operate based on the received operating instructions.
Further, the first device receives a start command and/or a stop command sent by the second device, and the first start time m is reset; and the ventricular assist device resets the second starting number n after receiving the stop command.
In one embodiment, if the target operation mode is the operation mode, controlling the ventricular assist device to start or stop according to the target operation state and the target operation command includes: when the target running state is the stop state and the target operation instruction is the first instruction, starting the ventricular assist device and determining that the target running state is the running state; and when the target operation state is the operation state and the target operation instruction is the second instruction, stopping the ventricular assist device and determining to enable the ventricular assist device to be in the stop state.
Wherein the first instruction is an instruction for instructing the ventricular assist device to start operation, such as a start instruction; the second instruction is an instruction that instructs the ventricular assist device to stop functioning, such as a stop instruction. In the operation mode, if the target operation state of the ventricular assist device is a normal state and the target operation instruction sent by the second device is a stop instruction, the first device can send the stop instruction to the ventricular assist device to stop the ventricular assist device from operating; if the target operation state of the ventricular assist device is a stop state or a fault state, and the target operation instruction sent by the second equipment is a starting instruction, the first equipment sends the starting instruction to the ventricular assist device to start the ventricular assist device to operate.
Further, when the target operation state of the ventricular assist device is the operation state and the target operation command sent by the second device is the start command, the first device may not operate and the ventricular assist device is continuously maintained in the normal state. When the target operation state of the ventricular assist device is a stop state and the target operation instruction sent by the second device is a stop instruction, the first device may not operate and the ventricular assist device continues to be in the stop state.
It should be noted that, the first apparatus may also detect whether the ventricular assist device fails in real time in the operation mode, and when the ventricular assist device is detected, the first apparatus does not send an activation instruction to the ventricular assist device to activate the ventricular assist device, and the first apparatus may receive an activation instruction sent by the second apparatus to activate the ventricular assist device, or may send state information that the ventricular assist device is in a failure state to the second apparatus to activate the ventricular assist device through the second apparatus.
In one embodiment, the method further comprises: if the target running state is a fault state, acquiring a second starting frequency; when the second starting frequency is less than or equal to a second threshold value, adding 1 to the second starting frequency, detecting whether the ventricular assist device is in a fault state, and if the ventricular assist device is in the fault state, repeating the step; otherwise, determining the target running state as a running state; and when the second starting times is greater than a second threshold value, sending the first information to the second equipment.
Wherein, in the operation mode, when the ventricular assist device fails and stops running, the ventricular assist device can be self-started. In particular, the first apparatus may obtain a second number of activations of the ventricular assist device to self-activate. If the second starting frequency is less than or equal to the second threshold, the ventricular assist device is self-started, so that the first equipment adds 1 to the second starting frequency, then detects the running state of the ventricular assist device, determines the target running state as the normal state if the running state of the ventricular assist device is the normal state, and if the running state of the ventricular assist device is still the fault state, the first equipment adds 1 to the second starting frequency, and the ventricular assist device is self-started again until the second starting frequency is greater than the second threshold. If the second starting frequency is greater than a preset second threshold, the ventricular assist device is failed to start automatically, the first device can send first information to the second device, and the first information can carry indication information that the ventricular assist device is in a failure state, so that the second device gives an alarm after receiving the first information. Or when the first starting times are larger than the first threshold value, the first equipment can alarm directly through the indicator lamp and the loudspeaker.
For example: in the operation mode, if a serious fault exists and the ventricular assist device stops running, acquiring a second starting frequency n; if the second starting frequency n is greater than 5, the ventricular assist device cannot be controlled to be in the running state through the first equipment, and the first equipment sends first information to the second equipment so as to display an alarm on the second equipment; if the second starting number n < =5, the ventricular assist device is started by itself, the ventricular assist device adds 1 to the second starting number n, the first device detects whether the ventricular assist device is in an operating state, and if the ventricular assist device is in a stop state, the second starting number n is repeatedly acquired.
The method further comprises the following steps: the first device records the modes which are passed by the operation process, including a first working mode which is entered after the first device is started and the working modes which are switched one by one, so as to increase the safety.
The method further comprises the following steps: in the normal mode, when the first device detects the failure of the ventricular assist device, an audio alarm is given; in the operation mode, when the first device detects that the ventricular assist device is in fault, in order to avoid interference of alarm sound to a doctor, the first device is in a mute state, audio alarm is not performed, and alarm is performed through the second device and the like. The first device is also provided with a mute key, and the mute can be cancelled by pressing the mute key.
In the control method of the ventricular assist device, the first equipment is set to be in the operation mode and the normal mode according to different use scenes of the ventricular assist device, so that the application requirements of the ventricular assist device in different use scenes are met. In the operation mode, the ventricular assist device can be started only according to the operation instruction of a doctor and cannot be started automatically, so that the interference to the doctor in the operation process is avoided; in order to avoid the condition that the ventricular assist device stops operating and causes life danger and even death of a patient, the ventricular assist device cannot be manually stopped in a normal mode, and can be automatically started after the ventricular assist device is accidentally stopped. Therefore, the user operation is limited by setting the starting mechanism and the stopping mechanism under different modes, and the safety of the patient is guaranteed.
In one embodiment, as shown in fig. 4, a method for controlling a ventricular assist device is provided, which is applied to a first apparatus, and the ventricular assist device controlled by the first apparatus is a pump, for example, to describe a detection procedure related to a normal mode, and includes the following steps:
after the first equipment is started, whether the first equipment is connected with the ventricular assist device or not is detected, if the first equipment is not connected with the ventricular assist device, an alarm is given, alarm information is sent to the second equipment to be displayed, and if the first equipment is connected with the ventricular assist device, a target running state of the ventricular assist device and a target working mode of the first equipment are obtained.
When the target operating mode of the first device is a normal mode, the method includes: detecting whether the ventricular assist device is stopped in real time during operation of the pump; if the ventricular assist device stops, the target operation state of the ventricular assist device is a fault state, and a first starting frequency m of the first equipment for starting the ventricular assist device is obtained; if the ventricular assist device operates, the target operation state of the ventricular assist device is a fault state, and a starting instruction is not sent to the ventricular assist device.
And after the first starting time m is obtained, comparing the first starting time m with a first threshold (such as 5 times), and if the first starting time m is greater than 5, sending first information to the second equipment so as to display an alarm on a monitor.
In one embodiment, as shown in fig. 5, a method for controlling a ventricular assist device is provided, which is described in the case of the first apparatus 102 in fig. 1, and includes the following steps:
after the first equipment is started, whether the first equipment is connected with the ventricular assist device or not is detected, if the first equipment is not connected with the ventricular assist device, an alarm is given, the alarm information is sent to the second equipment to be displayed, and if the first equipment is connected with the ventricular assist device, a target running state of the ventricular assist device and a target working mode of the first equipment are obtained.
When the target operational mode of the first device is a surgical mode, the method comprises: judging whether the received target operation instruction is a stop instruction or not, and stopping if the stop instruction is received; if the target operation instruction which is not received is not a stop instruction, whether the ventricular assist device is in failure or not is detected.
If the ventricular assist device is not in fault, the target operation state of the ventricular assist device is an operation state; if the failure occurs, the target operation state of the ventricular assist device is a failure state, a second starting frequency n is obtained, the obtained second starting frequency n is compared with a second threshold (for example, 5 times), a result obtained by failure detection is obtained, and the ventricular assist device is alarmed based on the result.
