[0047] Before the technical solutions of the embodiments of the present application are introduced, the background art of the embodiments of the present application is introduced first:
[0048] For patients using a ventricular assist device, a ventricular assist device is configured for each patient, and a doctor regularly and timely visits the patient's room to check the patient's condition and manually adjusts various operating parameters of the ventricular assist device according to the patient's condition, so that the ventricular assist device can more effectively help the patient improve the cardiac output.
[0049] However, in the actual use of the ventricular assist device, the doctor usually needs to adjust the operating parameters of the ventricular assist device on site according to experience and the current situation of the patient, that is, the use of the ventricular assist device requires medical staff to pay a large amount of time cost and workload, so that the ventricular assist device can effectively help the patient improve the cardiac output. Therefore, the ventricular assist device is still in the stage of manual control in the process of use, and cannot realize automatic control, and the assistance efficiency is limited.
[0050] In order to solve the problems in the prior art, the embodiments of the present application provide a ventricular assist device control system.
[0051] In the embodiments of the present application, each ventricular assist device is connected with a first communication interface, so that the processor of the central control system can perform signal transmission with the ventricular assist device, that is, the processor generates a corresponding adjustment instruction by acquiring the target object basic information, the target object physiological parameter information, and the current operating parameters of the ventricular assist device, and then the processor sends the adjustment instruction to the ventricular assist device through the first communication interface, so that the ventricular assist device adjusts the parameters according to the adjustment instruction, thereby realizing remote control of the ventricular assist device, and at the same time, the target object basic information and the target object physiological parameter information can be combined to determine the operating parameters suitable for the current target object, thereby reducing the time cost and workload of the staff, reducing the labor cost, and improving the assistance efficiency of the ventricular assist device to the target object.
[0052] Firstly, a ventricular assist device control system provided by an embodiment of the present application is introduced.
[0053] Figure 1 A system structure schematic diagram of a ventricular assist device control system provided by an embodiment of the present application is shown.
[0054] As Figure 1 shown, in the embodiment of the present application, the ventricular assist device control system comprises:
[0055] The central control system 10 comprises a processor 11 and at least one first communication interface 12 connected with the processor 11.
[0056] At least one ventricular assist device 20, and the first communication interface 12 is connected with the corresponding ventricular assist device 20.
[0057] In the embodiment, each ventricular assist device 20 corresponds to a target object one by one, that is, each ventricular assist device 20 can provide pumping power for the target object corresponding to the ventricular assist device 20.
[0058] As an example, the target object can be a patient, an animal or other test object, and in the embodiment, the target object is a patient.
[0059] As an example, at least one ventricular assist device 20 is usually arranged in each ward, and the ventricular assist device 20 being used in each ward can access the central control system 10 through the first communication interface 12 to realize remote control of the ventricular assist device 20.
[0060] In some embodiments, in order to realize accurate control of each ventricular assist device 20, the processor 11 is configured to acquire a first parameter of the target object corresponding to the ventricular assist device 20 and / or a second parameter of the ventricular assist device, wherein the first parameter can include patient basic information and patient physiological parameter information, and the second parameter can include a current running parameter, and an adjustment instruction of the corresponding ventricular assist device 20 is generated according to the patient basic information, the patient physiological parameter information and the current running parameter, and the adjustment instruction is sent to the ventricular assist device 20.
[0061] As an example, the patient basic information can include the age, gender, height and weight of the patient, the patient physiological parameter information can include cardiac output (CO), cardiac power output (CPO), cardiac preload (LVEDP), arterial blood pressure (ABP) and heart rate (HR), and the running parameter can include a pumping gear, a pumping flow, a perfusion flow rate and a perfusion liquid heparin content.
[0062] After the ventricular assist device 20 receives the corresponding adjustment instruction, the ventricular assist device 20 adjusts the current operation parameter according to the adjustment instruction to provide pumping power for the corresponding patient, thereby realizing real-time monitoring and remote control of the ventricular assist device 20.
[0063] In the embodiment of the present application, each ventricular assist device 20 is connected with the first communication interface 12, so that the processor 11 of the central control system 10 can transmit signals with the ventricular assist device 20, that is, the processor 11 generates a corresponding adjustment instruction by acquiring the patient basic information, the patient physiological parameter information and the current operation parameter of the ventricular assist device 20, and then the processor 11 sends the adjustment instruction to the ventricular assist device 20 through the first communication interface 12, so that the ventricular assist device 20 adjusts the parameter according to the adjustment instruction, thereby realizing remote control of the ventricular assist device 20, and at the same time, the patient basic information and the patient physiological parameter information can be combined to determine the pumping parameter suitable for the current patient, thereby reducing the time cost and workload of medical staff, reducing the labor cost, and improving the auxiliary efficiency of the ventricular assist device 20 to the patient.
[0064] In some embodiments, the central control system 10 further comprises a data input end 13 in communication connection with the processor, and the data input end 13 is used to receive the patient basic information and / or the patient physiological parameter information input by the user.
[0065] In the embodiment, when the processor 11 acquires the patient basic information and the patient physiological parameter information of the patient, the patient may be used for the first time, at this time, the medical staff can input the patient basic information and the patient physiological parameter information of the patient through the data input end 13, and it is worth noting that the patient basic information and the patient physiological parameter information input by the medical staff are obtained by the medical staff from other ways of obtaining the patient basic information and the patient physiological parameter, and then manually input into the central control system 10 by the medical staff.
[0066] In an optional embodiment, the central control system 10 further comprises a second communication interface 14, and the second communication interface 14 is connected with a target object information system.
[0067] In the embodiment, the target object information system can be a patient information system.
[0068] In the embodiment, the processor 11 is further specifically used to acquire the patient basic information of the patient corresponding to the ventricular assist device from the target object information system through the second communication interface 14.
[0069] When the ventricular assist device 20 is applied in a hospital or other medical institution, in the hospital or other medical institution, during the patient's hospitalization, the patient's basic information is usually input into the target object information system, at this time the processor 11 can be connected with the target object information system through the second communication interface 14, when it is necessary to control the ventricular assist device 20 of the patient, the patient's basic information can be directly obtained through the target object information system, so as to realize the real-time and rapid adjustment of the ventricular assist device 20.
[0070] In some embodiments, in order to maintain the consistency of data transmission, the first communication interface 12 and the second communication interface 14 are respectively connected with the ventricular assist device 20 and the target object information system through the target communication protocol.
[0071] As an example, the target communication protocol can include an HL7 protocol or a FHIR protocol, that is, in the field of medical equipment, in order to realize the electronic transmission between different applications, the standardized health information transmission standard can adopt the HL7 protocol or the FHIR protocol to allow data interaction between heterogeneous systems.
[0072] For example, the HL7 protocol can realize data transmission between the ward and patient information management, the laboratory system, the pharmacy system, the radiology system and the charging system, the FHLR protocol can realize communication on the Internet hospital, telemedicine and smart medical treatment, and can guarantee the real-time and accuracy of data transmission.
[0073] In some embodiments, the target protocol can also include other private transmission protocols, which can realize data transmission between the central control system 10 and the target object information system, which is not limited here.
[0074] In some embodiments, the central control system 10 further comprises a third communication interface 15 connected with the processor 11, and the third communication interface 15 is connected with a target object physiological parameter monitoring device.
[0075] The processor 11 is further specifically configured to obtain target object physiological parameter information from the target object physiological parameter monitoring device.
[0076] In this embodiment, since manual input of patient physiological parameter information may have a certain delay, the real-time of patient physiological parameter information cannot be guaranteed, therefore, the third communication interface 15 of the central control system 10 can be connected with the patient physiological parameter monitoring device, and in the case that the processor 11 needs to generate an adjustment instruction, the processor 11 can directly obtain the patient physiological parameter information from the patient physiological parameter monitoring device through the third communication interface 15, which is more convenient and fast.
[0077] As an example, in the case where the target object is a patient, the patient physiological parameter monitoring device can be a monitor, a sphygmomanometer or an electrocardiogram monitoring device.
[0078] In some embodiments, the central control system 10 can further comprise an alarm unit 16, which is in communication connection with the processor 11.
[0079] The processor 11 is further configured to generate alarm information in the case where the target object physiological parameter information is abnormal and / or the operation parameter of the ventricular assist device 20 is abnormal, and control the alarm unit 16 to start according to the alarm information.
[0080] In the present embodiment, in the process of remote control of the ventricular assist device 20, since the processor 11 can acquire the patient physiological parameter information, the normal physiological parameter information corresponding to the patient can be pre-stored in the processor 11, and in the case where the patient physiological parameter information acquired through the third communication interface 15 is not within the range of the normal physiological parameter information, the processor 11 can determine that the patient physiological parameter information of the patient is abnormal, at this time, the alarm information can be generated according to the abnormal patient physiological parameter information, for example, the alarm information can comprise the abnormal patient physiological parameter information, at this time, the processor 11 can control the alarm unit 16 to start according to the alarm information.
[0081] In another example, the processor 11 can acquire the operation parameter of the ventricular assist device 20, and the current operation parameter of the ventricular assist device 20 can comprise the operation current, the operation voltage, the device state and the motor speed, similarly, the processor 11 can determine whether the operation parameter of the ventricular assist device 20 is within the normal range, if not, the alarm information can be generated to control the alarm unit 16 to start.
[0082] In some embodiments, the alarm unit 16 can comprise an audible and visual alarm, which starts in the case where the alarm unit 16 needs to start; as another example, the alarm unit 16 can further comprise an SMS / phone alarm, in the case where the alarm unit 16 needs to start, the processor 11 can send an SMS or make a phone call to the medical staff bound to the central control system 10 through a communication device to remind the medical staff.
[0083] In some embodiments, in the process of generating the adjustment instruction by the processor 11, an adjustment model can be constructed according to the historical adjustment instruction of the medical staff, and the adjustment instruction is determined through the adjustment model.
[0084] As an example, the adjustment model can be a neural network model. During training, patient historical basic information, patient historical physiological parameter information, and ventricular assist device 20 historical adjustment parameters can be used as a training set to train the adjustment model to obtain a trained adjustment model. The training method is a conventional training method, which will not be described in detail here.
[0085] In some other embodiments, the ventricular assist device 20 can include:
[0086] A blood pumping motor 21 for adjusting the blood pumping power of the target object.
[0087] A fourth communication interface 22 connected with the first communication interface 12 for sending device running information and receiving adjustment instructions.
[0088] A control device 23 in communication connection with the fourth communication interface 22 for outputting target running parameters of the blood pumping motor 21 according to the adjustment instructions to realize the control of the blood pumping motor 21 and provide blood pumping power for the corresponding target object.
[0089] In this embodiment, the ventricular assist device 20 is in communication connection with the first communication interface 12 through the fourth communication interface 22, that is, the control device 23 can send device running information through the fourth communication interface 22, and can also receive adjustment instructions sent by the processor 11 through the fourth communication interface 22.
[0090] After the control device 23 receives the adjustment instructions, the control device 23 can output target running parameters of the blood pumping motor 21 according to the adjustment instructions to realize the control of the blood pumping motor 21 and provide blood pumping power for the corresponding patient.
[0091] As an example, the adjustment instructions can include a target blood pumping gear, and the target blood pumping parameters can include a target rotating speed and a target driving voltage.
[0092] In the case where the control device 23 outputs the target running parameters of the blood pumping motor 21 according to the adjustment instructions, the control device 23 is further specifically used for:
[0093] Obtaining current blood pumping parameters of the blood pumping motor 21;
[0094] Adjusting the current rotating speed of the blood pumping motor 21 according to the current blood pumping gear and the target blood pumping gear to obtain a target rotating speed of the blood pumping motor 21;
[0095] Determining a target driving voltage according to the target rotating speed;
[0096] Controlling the blood pumping motor 21 to run based on the target driving voltage to realize the blood pumping control of the blood pumping motor 21 and provide blood pumping power for the corresponding patient.
[0097] In the embodiment, in the process of adjusting the blood pumping parameter of the ventricular assist device 20, the control device 23 needs to obtain the current blood pumping parameter of the blood pumping motor 21, for example, the current blood pumping parameter includes the current blood pumping gear and the current rotating speed of the blood pumping motor 21, and then the target rotating speed is obtained by adjusting the current rotating speed of the blood pumping motor 21 through the current blood pumping gear and the target blood pumping gear, that is, each blood pumping gear corresponds to a rotating speed range of the blood pumping motor 21, and the target rotating speed can be determined through the current blood pumping gear and the target blood pumping gear. After obtaining the target rotating speed, the target driving voltage of the blood pumping motor 21 can be determined according to the fitting formula or other rotating speed-voltage calculation formula, so as to control the blood pumping motor 21 to operate at the target rotating speed.
[0098] It can be understood that the operation of the blood pumping motor 21 is determined by the input driving voltage, so the control device 23 can control the rotating speed of the blood pumping motor 21 by controlling the target driving voltage.
[0099] In some embodiments, the target driving voltage can be determined according to the fitting formula of the rotating speed and the voltage, and can also be determined through other rotating speed-voltage calculation formula in the motor field, which will not be described here.
[0100] In the embodiment, in order to be able to cope with the sudden situation of the patient, the ventricular assist device 20 further comprises:
[0101] The on-site starting unit 24 is electrically connected with the control device 23, and is used for controlling the ventricular assist device 20 to enter the manual control state, and generating an on-site control signal to make the control device 23 send the on-site control signal to the central control system 10, wherein the on-site control signal is used to shield the adjustment instruction.
[0102] The remote starting unit 25 is electrically connected with the control device 23, and is used for controlling the ventricular assist device 20 to enter the automatic control state, and generating a remote control signal to make the control device 23 send the remote control signal to the central control system 10, and in the case that the central control system 10 receives the remote control signal, the central control system 10 sends the adjustment instruction to the ventricular assist device 20.
[0103] Specifically, the medical staff can switch the on-site control and the remote control by adjusting the on-site starting unit 24 or the remote starting unit 25, and it is worth noting that the permission of the on-site control signal is higher than that of the remote control signal for the processor 11, that is, in the case that the processor 11 receives the on-site control signal sent by the ventricular assist device 20, the ventricular assist device 20 can shield the adjustment instruction, and the medical staff can adjust the blood pumping parameter of the ventricular assist device 20.
[0104] When the ventricular assist device 20 opens the remote start unit 25, the ventricular assist device 20 enters an automatic control state, and the control device 23 generates a remote control signal, at this time, the processor 11 can send an adjustment instruction to the ventricular assist device 20, and at the same time, the control device 23 can also automatically adjust the blood pumping parameter according to the adjustment instruction, to realize remote control of the ventricular assist device 20.
[0105] It is worth noting that when the ventricular assist device 20 is in an automatic control state, after the blood pumping motor 21 runs at the current blood pumping gear for a preset period, the processor 11 generates a new adjustment instruction to realize dynamic control to meet the blood pumping needs of the patient.
[0106] With reference to Figure 2 The application also provides a control method of a ventricular assist device control system, which can include S301-S305:
[0107] S301, the central control system obtains first parameter information of a corresponding target object and / or second parameters of a ventricular assist device;
[0108] S302, the central control system generates an adjustment instruction according to the first parameter and the second parameter;
[0109] S303, the central control system sends the adjustment instruction to the ventricular assist device corresponding to the current running parameter;
[0110] S304, the ventricular assist device receives the adjustment instruction;
[0111] S305, the ventricular assist device adjusts the current running parameter according to the adjustment instruction.
[0112] As an example, the first parameter can include target object basic information and target object physiological parameter information, and the second parameter can include the current running parameter.
[0113] In the application, each ventricular assist device is connected with a first communication interface, so that the processor of the central control system can transmit signals with the ventricular assist device, that is, the processor generates a corresponding adjustment instruction by obtaining the target object basic information, the target object physiological parameter information, and the current running parameter of the ventricular assist device, and then sends the adjustment instruction to the ventricular assist device through the first communication interface, so that the ventricular assist device adjusts the parameter according to the adjustment instruction, thereby realizing remote control of the ventricular assist device, and at the same time, the target object basic information and the target object physiological parameter information can be combined to determine the running parameter suitable for the current target object, thereby reducing the time cost and workload of the staff, reducing the labor cost, and improving the auxiliary efficiency of the ventricular assist device to the target object.
