[0019] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described below clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, and are not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative labor are included in the protection scope of the present disclosure.

[0020] Referring to FIG. 1, a schematic diagram of an infusion pump structure provided by one embodiment of the present disclosure is shown. Infusion pump control system 100 is disposed within infusion pump 200 and controls the operation of infusion pump 200. RThe infusion pump control system 100 is a dual controller system including a dual controller unit 10. The dual controller unit 10 includes a monitoring controller 11 and a main controller 12, both of which are MCUs (Microcontroller Units), connected to each other. The specific model number of the monitoring controller 11 may be STM32, and the specific model number of the main controller 12 may be STM32F407ZGT6. The monitoring controller 11 is also connected to a switch button and a power supply. When the switch button is turned on, the infusion pump is started, and the monitoring controller 11 controls the power supply to start supplying power to the infusion pump. The monitoring controller 11 can actively obtain or passively receive a communication signal from the main controller 12. The function of the communication signal is to determine whether the two maintain normal communication according to the contents transmitted and received by each other, and the communication signal may be a heartbeat signal. If the communication signal sent from the main controller 12 is abnormal, indicating that the main controller 12 may be unable to continue operating due to a fault, the monitoring controller 11 first turns off the motor of the injection pump, then turns off the injection pump, i.e., cuts off the power supply to the injection pump, triggers the emergency temporary power supply to start powering the alarm module, and controls the alarm module to issue an alarm.

[0021] Furthermore, when the infusion pump is started and begins to operate, the main controller 12 samples the operation data of the infusion pump. Specifically, it collects operation data of the infusion pump's motor, screen, buttons, sensors, slot-type photocoupler, limit switch, sound and light alarm module, storage device, external power supply, etc., and determines whether there is an abnormality in the sampled data that triggers an alarm. If there is, it triggers the alarm module to issue an alarm. The alarm triggered by the abnormal sampled data is different from the mode of the alarm triggered by the failure of the main controller 12. In contrast, the alarm mode caused by the failure of the main controller 12 is more noticeable, such as the alarm light flashing most frequently, the color is red, the alarm sound is at the loudest volume, and red characters flashing on the infusion pump screen at the same time.

[0022] 2, a schematic diagram of the structure of an infusion pump control system provided by one embodiment of the present disclosure is shown, which includes a dual controller unit 10, a dual power supply unit 20, a data collection unit 30, a button control unit 40, and an alarm module 50.

[0023] The dual controller unit 10 includes a supervisory controller 11 and a main controller 12 .

[0024] The dual power supply unit 20 includes a power supply source 21 and an emergency temporary power supply 22 .

[0025] The supervisory controller 11 is connected to a main controller 12 and is also connected to the infusion pump power supply 21 , the button control unit 40 and the alarm module 50 .

[0026] The monitoring controller 11 is connected to the main controller 12 , the data collection unit 30 , the emergency temporary power supply 22 , and the alarm module 50 .

[0027] The emergency temporary power supply 22 is also connected to the power supply 21 and the alarm module 50. When it detects that the power supply 21 stops supplying power, the emergency temporary power supply 22 starts up and supplies power to the alarm module 50 instead of the power supply 21.

[0028] The button control unit 40 includes a control switch 41, and the monitoring controller 11 is connected to the control switch 41. When the control switch 41 is turned on, the monitoring controller 11 starts up the power supply 21 to supply power, and supplies power to the injection pump including the monitoring controller 11 and the main controller 12.

[0029] The main controller 12 transmits a communication signal to the monitoring controller 11 and controls the data collection unit 30 to collect operation data of the infusion pump, determines whether the infusion pump is operating normally based on the operation data, and controls the alarm module 50 to issue an alarm if an abnormality occurs. R The operational data includes operational data of the infusion pump motor, power supply, emergency power supply, display screen, infusion device, various buttons, etc. The operational data can represent whether the infusion pump is in a normal operating state.

[0030] The monitoring controller 11 continuously receives a communication signal from the main controller 12, and if the communication signal is abnormal, it determines that the main controller 12 is broken, cuts off the power supply 21 for the injection pump, and transmits an alarm signal. death The power supply cut-off triggers the activation of the emergency temporary power source 22 to supply power to the alarm module 50, and the alarm module 50 issues an alarm in response to the alarm signal. The alarm at this time is the highest level alarm. The most prominent and highest level alarm includes the highest alarm volume, the highest vibration frequency of the beep sound, the flashing of red characters, and the longest duration, etc.

[0031] The communication signal is acquired by the monitoring controller 11 from the main controller 12 at preset intervals, or the main controller 12 actively transmits the communication signal to the monitoring controller 11. Depending on the time and content of the communication signal acquired by the monitoring controller 11, it is determined whether or not the main controller 12 has failed.

[0032] The above infusion pump control system may have another connection manner, that is, the monitoring controller 11 is connected to the main controller 12, and also connected to the power supply 21 of the infusion pump, the emergency temporary power supply 22, and the alarm module 50.

[0033] The monitoring controller 11 receives a communication signal from the main controller 12. If the communication signal is abnormal, the monitoring controller 11 cuts off the power supply 21 of the injection pump and starts the emergency temporary power supply 22 to supply power to the alarm module 50. The monitoring controller 11 also controls the alarm module 50 to issue an alarm.

[0034] In this embodiment, the injection pump control system is provided with dual controllers and dual power supplies, and the main controller sends a communication signal to the monitoring control unit. deathThe control data acquisition unit collects operation data of the infusion pump, judges whether the infusion pump is operating normally according to the operation data, and controls the alarm module to send an alarm when an abnormality occurs, thereby separately maintaining the normal operation state of the infusion pump. The monitoring controller monitors whether the main controller is faulty through a communication signal with the main controller, and when a fault occurs, cuts off the power supply to the infusion pump from the power supply, triggers an emergency temporary power supply to supply power to the alarm module, and controls the alarm module to send an alarm at the same time, thereby suppressing the possibility that the control system with a single controller will be unable to respond as a whole controlled pump system due to the failure of the controller, and unable to send an alarm immediately, causing further damage to the infusion pump system, and realizing timely power off and alarm sending after the failure of the main controller, improving the efficiency of responding to faults, and improving the safety of the infusion pump operation.

[0035] Further, referring to FIG. 3, it is a schematic diagram of the connection structure of the infusion pump control system and other modules of the infusion pump provided according to another embodiment of the present disclosure.

[0036] Furthermore, the injection pump includes an electric motor, specifically a stepping motor 60, and the monitoring controller 11 and the main controller 12 are connected to the electric motor 60 of the injection pump. When the communication signal is abnormal, the monitoring controller 11 controls the electric motor 60 to stop operating in a preset slow stop mode. R In the gradual stop mode, the time required for the motor 60 to decelerate to 0 and the rules for deceleration are set, and the operation of the motor 60 is first stopped and then the power supply 13 is turned off.

[0037] Furthermore, the main controller 12 is connected to an electric motor 60 and controls the electric motor 60 to drive the pushing and pulling of the injection push handle of the syringe, which in turn pushes and pulls the injection push rod of the syringe to complete the injection operation.

[0038] Furthermore, the main controller 12 is connected to the master device interface 70 of the infusion pump, and a radio frequency unit, such as a radio frequency ablation device, is connected to the infusion pump to control the infusion pump to complete the infusion task. When the master device control line detects that the master device interface 70 is connected to the radio frequency unit, the main controller 12 controls the infusion pump to enter the slave device mode. death That is, the input device of the infusion pump, such as a touch screen, mouse, keyboard, etc., is controlled so that it stops responding to input operations.

[0039] The button control unit 40 further includes a mute switch 42, and the main controller 12 is also connected to the mute switch 42. When the mute switch 42 is turned on, the main controller 12 detects the current output sound signal, determines the module that outputs the sound signal, and selects an output method to cut off the sound signal according to the nature of the module, such as cutting off the output end of the sound structure, or cutting off the signal input at the input end of the module and cutting off the output of the sound signal. The sound signal is, for example, an alarm beep or alarm sound in the alarm module 50.

[0040] Additionally, the infusion pump is equipped with a touch screen 80 through which setting data for the infusion pump can be obtained.

[0041] Furthermore, the data collection unit 30 includes a pressure detection sensor 31 and an injection position detection device 32 .

[0042] The pressure detection sensor 31 is disposed in the push handle of the injector and measures the pressure of the stepping motor 60 on the push handle. R The push handle can push the injection push rod of the injector, and by detecting this pressure, the pressure of the stepper motor 60 applied to the push handle can be adjusted to control the injection flow rate or amount.

[0043] The injection position detection device 32 includes a photocoupler and a light blocking plate, the light blocking plate is driven by a stepping motor 60 to perform a linear motion and moves synchronously with the push rod of the injector. Through the cooperation of the light blocking plate and the photocoupler, the position of the push rod of the injector can be obtained, and further, the remaining injection amount of the injector and other working status data can be calculated according to a preset algorithm.

[0044] The main controller 12 obtains the working state data of the stepping motor 60, the pressure detection sensor 31, the injection position detection device 32 and the touch screen 80, and judges according to these data whether the corresponding modules or devices are working normally or not, and if not, triggers the alarm module 50 to issue an alarm according to the preset processing logic. The alarm mode of the alarm module 50 can be one or a combination of any of the methods such as sound, light, vibration, etc.

[0045] 4, which is a circuit connection structure diagram of some modules of the infusion pump in this embodiment, including a monitoring controller and a main controller. Specifically, referring to FIG. 4, the monitoring controller is connected to the main controller, the voice alarm / beep alarm module, the alarm indicator (LED light), the switch button, etc. The main controller is also connected to the injector push-pull rod position detection module, the injector specification detection module, the communication interface, the memory, the display screen, the LED light status display module showing the working status of the infusion pump, etc. The connection method of the receiving circuit is as shown in the figure, and the marks of the connection circuit are common abbreviations in the electronic circuit and communication fields, for example, RXD (receive data) represents data reception, TXD (Transmit Data) represents data transmission, I / O (Input / Output) represents input and output, etc., which will not be described one by one here.

[0046] In this embodiment, a dual controller is installed in the infusion pump control system, and the monitoring controller monitors whether the main controller is faulty through a communication signal with the main controller, and when a fault occurs, cuts off the power supply from the power supply to the infusion pump, triggers the emergency temporary power supply to power the alarm module, and controls the alarm module to send an alarm at the same time, thereby suppressing the possibility that the control system with a single controller will cause the entire control pump system to be unable to respond due to the controller failure, and will not be able to send an alarm immediately, causing further damage to the infusion pump system, and realizing the timely power off and alarm sending after the main controller failure, improving the efficiency of responding to faults, and improving the safety of the infusion pump operation. The monitoring controller is only responsible for monitoring these simple and important functions such as the failure of the main controller, switching power supply, and alarm, so that the possibility of the failure of the monitoring controller itself can be reduced. At the same time, the main controller samples the operation data of the infusion pump system, immediately detects other faults in the system, and cooperates with the monitoring controller to improve the fault tolerance of the infusion pump control system and reduce the possibility of not being able to respond in time when a fault occurs.

[0047] Referring to FIG. 5, a flow chart of a control method for an infusion pump control system provided by an embodiment of the present disclosure. As shown in FIG. 5, the control method for the infusion pump control system may be applied to an infusion pump, and may be executed by a dual controller unit in the control system for the infusion pump. The configuration of the control system for the infusion pump may refer to the description of the embodiment shown in FIGS. 2 to 4 above. The method specifically includes the following:

[0048] Step S501: When it is detected that the control switch is turned on, the monitoring controller in the dual controller unit starts to activate the power supply and supply power.

[0049] The dual controller unit includes a supervisory controller and a main controller.

[0050] When the control switch of the infusion pump is turned on, the supervisory controller activates the power supply to power the infusion pump.

[0051] Step S502: The main controller in the dual controller unit sends a communication signal to the monitoring controller and controls the data collection unit to collect operation data of the infusion pump, judges whether the infusion pump is operating normally based on the operation data, and controls the alarm module of the infusion pump to issue an alarm if an abnormality occurs.

[0052] The main controller sends a communication signal to the monitoring controller at a preset period, and the communication signal may be a heartbeat signal. If the communication signal is abnormal, the monitoring controller determines that a preset fault has occurred in the main controller, and the preset fault includes a serious fault such as a short circuit of the main controller. The monitoring controller then cuts off the running motor, and further cuts off the power supply of the infusion pump, triggers the emergency temporary power supply to start powering the alarm module, and triggers the alarm module to issue an alarm in a preset manner.

[0053] In addition, the main controller controls the data collection unit to collect operation data of the infusion pump, judges whether the infusion pump is working normally according to the operation data, and controls the alarm module of the infusion pump to issue an alarm when an abnormality occurs. The operation data can be compared with the preset standard data in the system to confirm whether the working state of the infusion pump is normal.

[0054] Step S503: The monitoring controller continuously acquires the communication signal transmitted from the main controller, and if the communication signal is abnormal, cuts off the power supply from the power source and sends an alarm signal, and the power cut-off triggers the activation of the emergency temporary power source to supply power to the alarm module, and the alarm module issues an alarm according to the alarm signal.

[0055] The monitoring controller continuously obtains the heartbeat signal sent from the main controller, and if the heartbeat signal is abnormal, for example, the heartbeat signal from the main controller cannot be received at a preset time and frequency, or the packets in the heartbeat signal are abnormal, it indicates to the main controller that a preset fault has occurred which will adversely affect the operation of the infusion pump, and the operation of the infusion pump should be stopped immediately.

[0056] The preset faults include faults that prevent the main controller from continuing to operate, such as a short circuit in the main controller's internal circuit and a line fault in the main controller.

[0057] In addition to being connected to the main controller, the monitoring controller is also connected to the motor of the infusion pump, the power supply, the temporary power supply, and the alarm module, where the alarm module includes an audio alarm module and an optical alarm module, and the power supply is an external power source.

[0058] When the monitoring controller determines that the main controller is faulty, it immediately cuts off the power supply of the infusion pump and sends an alarm signal. The cutoff of the power supply triggers the activation of the emergency temporary power supply to power the alarm module, and the alarm module issues an alarm in response to the alarm signal.

[0059] In this embodiment, a dual controller is installed in the infusion pump control system, and the main controller sends a communication signal to the monitoring control unit. death The control data acquisition unit collects operation data of the infusion pump, judges whether the infusion pump is operating normally according to the operation data, and controls the alarm module to send an alarm when an abnormality occurs, thereby separately maintaining the normal operation state of the infusion pump. The monitoring controller monitors whether the main controller is faulty through a communication signal with the main controller, and when a fault occurs, cuts off the power supply to the infusion pump from the power supply, triggers an emergency temporary power supply to supply power to the alarm module, and controls the alarm module to send an alarm at the same time, thereby suppressing the possibility that the control system with a single controller will be unable to respond as a whole controlled pump system due to the failure of the controller, and unable to send an alarm immediately, causing further damage to the infusion pump system, and realizing timely power off and alarm sending after the failure of the main controller, improving the efficiency of responding to faults, and improving the safety of the infusion pump operation.

[0060] 6, a flow chart of a control method for an infusion pump control system provided by another embodiment of the present disclosure. The control method for an infusion pump control system can be applied to the infusion pump control system, and the method includes:

[0061] Step S601: When it is detected that the control switch is turned on, the monitoring controller in the dual controller unit starts to activate the power supply and supply power.

[0062] The dual controller unit includes a supervisory controller and a main controller.

[0063] When the control switch of the infusion pump is turned on, the supervisory controller activates the power supply to power the infusion pump.

[0064] Step S602: The main controller in the dual controller unit sends a communication signal to the monitoring controller and controls the data collection unit to collect operation data of the infusion pump, judges whether the infusion pump is operating normally based on the operation data, and controls the alarm module of the infusion pump to issue an alarm if an abnormality occurs.

[0065] The main controller sends a communication signal to the monitoring controller at a preset period, and the communication signal may be a heartbeat signal. When the communication signal is abnormal, the monitoring controller determines that a preset fault occurs in the main controller, and the preset fault includes a major fault such as a short circuit of the main controller. The monitoring controller then cuts off the working motor, cuts off the power supply of the infusion pump, triggers the emergency temporary power supply to start powering the alarm module, and triggers the alarm module to issue an alarm in a preset manner, such as flashing yellow characters, low volume, and low frequency, which is less conspicuous than the alarm when a preset fault occurs in the main controller.

[0066] In addition, the main controller controls the data collection unit to collect operation data of the infusion pump, judges whether the infusion pump is working normally according to the operation data, and controls the alarm module of the infusion pump to issue an alarm when an abnormality occurs. The operation data can be compared with the preset standard data in the system to confirm whether the working state of the infusion pump is normal.

[0067] Specifically, the operational data includes operational data of the motor, power supply, emergency temporary power supply, display screen, injection device, various buttons, etc., and can represent the operating state of the injection pump.

[0068] Step S603: The monitoring controller continuously obtains the communication signal sent from the main controller, and when the communication signal is abnormal, controls the motor of the infusion pump to gradually stop working in a preset slow-stop mode.

[0069] If the heartbeat signal is abnormal, for example, if the heartbeat signal from the main controller cannot be received at the preset time and frequency, or if the packets in the heartbeat signal are abnormal, it indicates to the main controller that a preset fault has occurred which will have an adverse effect on the operation of the infusion pump, and the operation of the infusion pump needs to be stopped, so that the motor is first controlled to stop gradually, thereby preventing damage to the equipment due to a sudden stop.

[0070] Step S604: The monitoring controller cuts off the power supply of the power supply and sends an alarm signal, and the power cut triggers the activation of the emergency temporary power supply to power the alarm module, and the alarm module issues an alarm according to the alarm signal.

[0071] Furthermore, when the main controller detects that the master device control line of the infusion pump is connected to the radio frequency unit, the main controller controls the input device of the infusion pump to stop responding to input operations, and executes the command issued by the radio frequency unit. When the main controller detects that the master device control line of the infusion pump is connected to the radio frequency unit, that is, controls the input device of the infusion pump, such as a keyboard, a mouse, a touch screen, etc., to stop responding to input operations, and all operation instructions are input by the radio frequency unit, which is the master device, and the infusion pump is controlled by the operation instructions from the radio frequency unit. The radio frequency unit may specifically be a cauterization device.

[0072] In addition, when detecting that the mute button is pressed, the main controller detects the currently output audio signal and correspondingly blocks the output of the audio signal. For example, when an alarm module executes audio and light alarm, it detects that the mute button is pressed and the alarm module is prohibited from outputting the audio signal.

[0073] For other technical details of this embodiment, reference may be made to the description of the embodiment shown in FIGS.

The monitoring controller monitors whether the main controller is faulty through a communication signal with the main controller, and when a fault occurs, cuts off the power supply to the infusion pump from the power supply, triggers the emergency temporary power supply to power the alarm module, and controls the alarm module to send an alarm at the same time, thereby suppressing the possibility that the control system by a single controller will be unable to respond as a whole control pump system due to the failure of the controller, unable to send an alarm immediately, and causing further damage to the infusion pump system, realizing timely power off and alarm sending after the failure of the main controller, improving the efficiency of responding to faults, and improving the safety of the infusion pump operation. The monitoring controller is only responsible for monitoring these simple and important functions such as the failure of the main controller, switching power supply, and alarm, so that the possibility of the failure of the monitoring controller itself can be reduced. At the same time, the main controller samples the operating data of the infusion pump system, immediately detects other faults in the system, and cooperates with the monitoring controller to improve the fault tolerance of the infusion pump control system and reduce the possibility of not being able to respond in time when a fault occurs.
