Detailed Description
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
The embodiment of the invention can be applied to the infusion pump which needs to perform power-off processing on the processing module, the processing module in the infusion pump can receive the power of the power supply module and control the infusion pump body to work, so that the infusion speed of the infusion catheter in the infusion pump body is controlled, and the medicine is injected into the body of a patient. When the power supply stopping intention exists, the processing module can store related data such as the infusion speed and the like, and stops receiving the power of the power supply module after the storage is finished, so that the infusion pump body stops working.
In one embodiment of the present invention, the infusion pump may specifically include a power module and an infusion pump control device, and the infusion pump control device may specifically include a tact switch, a detection module, and a processing module. The power supply module can supply power to the processing module so as to enable the processing module to be in a working state. If the pressing operation of the user on the tact switch is received, the detection module detects that the state of the tact switch is a conducting state, the processing module determines the conducting time of the tact switch according to the detection result of the detection module, and determines the power supply stopping intention of the user under the condition that the conducting time of the tact switch exceeds the set time, so that the processing module processes tasks and data according to the power supply stopping intention, the power of the power supply module is stopped being received after the tasks and the data are processed, and the power-off processing of the processing module can be achieved.
The state of the processing module of the embodiment of the present invention may specifically include:
shutdown state: and when the processing module stops working, the power supply module does not supply power to the processing module any more, and the infusion pump body connected with the processing module cannot execute corresponding operation.
The working state is as follows: the processing module is in a corresponding state when working normally, at the moment, the power supply module supplies power to the processing module, and the infusion pump body connected with the processing module can execute corresponding operation.
A dormant state: the processing module is in a corresponding state when in standby, at the moment, the power supply module supplies power to the processing module, and the infusion pump body connected with the processing module cannot execute corresponding operation.
Example one
Referring to fig. 1, a schematic structural diagram of an infusion pump control device according to an embodiment of the present invention is shown.
The infusion pump control device 1 shown in fig. 1 specifically includes: the touch switch 11, the detection module 12 and the processing module 13; wherein, the detection module 12 detects the state of the tact switch 11; the processing module 13 is connected to the detection module 12 and receives power from the power module 2.
The processing module 13 obtains the on-time of the tact switch 11 according to the detection result of the detection module 12 when the processing module is in the working state, and processes the task and the data when the on-time exceeds the set time, so as to stop receiving the power of the power module 2 after completing the processing of the task and the data.
In a case where the user presses the tact switch 11, the detection module 12 receives a pressing operation of the tact switch 11, and determines that the tact switch 11 is in an on state. Alternatively, when the user cancels the pressing of the tact switch 11, the detection module 12 receives the lifting operation of the tact switch 11, and determines that the tact switch 11 is in the on-off state.
In the embodiment of the present invention, an input end of the detection module 12 is connected to the tact switch 11, an output end of the detection module 12 is connected to the processing module 13, and the detection module 12 is configured to detect whether the tact switch 11 is turned on. Alternatively, when the tact switch 11 is in different states (such as a conducting state and a conducting stop state), the voltage at the output end of the detection module 12 is different, and the processing module 13 may determine the conducting time of the tact switch 11 in the conducting state according to the voltage variation at the output end of the detection module 12.
The processing module 13 may be in an operating state when receiving the power of the power module 2, and when the processing module 13 is in the operating state and detects that the on time of the tact switch 11 exceeds the set time, the processing module processes an incomplete task and saves related data, so as to stop receiving the power of the power module 2 after completing task processing and data saving. In the case where the reception of the power supply module 2 is stopped, the processing module 13 may enter a shutdown state.
Alternatively, the processing module 13 in the embodiment of the present invention may be a system circuit for controlling an infusion pump body connected thereto, and the processing module 13 acts on an infusion tube in the infusion pump body to achieve the purpose of controlling the infusion speed. When the processing module 13 is in the operating state, the infusion pump body can be controlled to perform corresponding operations, that is, the infusion pump body performs infusion to inject drugs into the patient, and when the processing module 13 is in the shutdown state, the infusion pump body cannot perform corresponding operations, that is, the infusion pump body stops infusion.
The embodiment of the invention can support a user to control the processing module 13 to enter the shutdown state from the working state or enter the working state from the shutdown state by controlling the conducting time of the tact switch 11.
According to one embodiment, when the processing module 13 is in the power-off state, the pressing operation of the tact switch 11 may cause the processing module 13 to enter the operating state from the power-off state. When the processing module 13 enters the working state and detects that the on-time of the tact switch 11 is longer than the set time for the first time, the processing module 13 may maintain its own state as the working state, and further control the infusion pump body connected thereto to perform corresponding operations.
According to another embodiment, when the processing module 13 is in the working state and detects that the on-time of the tact switch 11 is longer than the set time again, the processing module 13 may process the uncompleted task and store the related data, so as to enter the shutdown state from the working state after completing the task processing and data storage, and at this time, the infusion pump body connected thereto cannot perform the corresponding operation.
In an alternative embodiment of the present invention, the processing module 13 may comprise a processing unit, which may include, but is not limited to: an MCU (Micro Control Unit), a CPU (Central Processing Unit), an MPU (Microprocessor Unit), and the like. The detection module 12 may be connected to a processing unit in the processing module 13, and the processing unit determines the on-time of the tact switch according to the detection result of the detection module, and processes tasks and data if the on-time exceeds a set time.
Referring to fig. 2, a schematic structural diagram of another infusion pump control device according to an embodiment of the invention is shown.
With respect to the infusion pump control device 1 shown in fig. 1, the infusion pump control device 1 shown in fig. 2 may further include: and the switch module 14 is respectively connected with the tact switch 11, the power module 2 and the processing module 13, and is used for controlling the connection between the power module 2 and the processing module 14 according to the state of the tact switch 11 and/or the instruction sent by the processing module 13.
If the switch module 14 is in the on state, the connection between the power module 2 and the processing module 13 may be established, that is, the power module 2 may supply power to the processing module 13, so that the processing module 13 is in the working state. Alternatively, if the switch module 14 is in the off state, the connection between the power module 2 and the processing module 13 may be disconnected, that is, the power module 2 does not supply power to the processing module 13, so that the processing module 13 is in the off state.
The following describes a power supply process of the infusion pump control device:
alternatively, in the case that the processing module 13 is in the shutdown state, the switch module 14 may establish the connection between the power module 2 and the processing module 13 according to the conducting state of the tact switch 11. Under the condition that the processing module 13 is in the shutdown state, when the user presses the tact switch 11, the tact switch 11 is in the on state, at this time, the switch module 14 may be turned on according to the on state of the tact switch 11, so as to establish the connection between the power module 2 and the processing module 13, that is, the power module 2 may supply power to the processing module 13, so that the processing module 13 is in the working state.
Optionally, the processing module 13 sends a turn-on instruction to the switch module 14 when the processing module 13 is in the working state and it is detected for the first time that the on-time of the tact switch 11 exceeds the set time, so that the switch module 14 maintains the connection between the power module 2 and the processing module 13 according to the turn-on instruction.
Specifically, after the tact switch 11 establishes the connection between the power module 2 and the processing module 13, the processing module 13 is in a working state, and if the pressing time of the tact switch 11 exceeds the set time, that is, the processing module 13 first detects that the on-time of the tact switch 11 exceeds the set time, in this case, the processing module 13 may send a turn-on instruction to the switch module 14, so that the switch module 14 continues to maintain the turn-on state according to the turn-on instruction, so that the power module 2 is continuously connected with the processing module 13, the power module 2 may supply power to the processing module 13, and the processing module 13 is in the working state. In this case, if the lifting operation of the tact switch 11 is detected, the processing module 13 may still send the on command to the switch module 14, and the switch module 14 may keep the on state according to the on command once receiving the on command.
The power-off process of the infusion pump control device is explained as follows:
the processing module 13 processes the task and the data when the processing module is in the working state and the on-time of the tact switch 11 is not detected for the first time to exceed the set time, and sends a closing instruction to the switch module 14 after the processing of the task and the data is completed, so that the switch module 14 disconnects the connection between the power module 2 and the processing module 13 according to the closing instruction and the on-off state of the tact switch 11. It should be noted that, after the processing module 13 is in the operating state, the number of times that the on time of the tact switch 11 is detected to exceed the set time may be counted to obtain "first time" and "non-first time" in the embodiment of the present invention.
When the processing module 13 is in a working state, the processing module 13 can control the infusion pump body connected with the processing module to execute corresponding operation, and when the pressing operation of the tact switch 11 is received again and the pressing time of the tact switch 11 exceeds the set time, that is, the processing module 13 detects that the on time of the tact switch 11 exceeds the set time again, the processing module 13 can determine that the power supply stopping intention exists in the user and determine that the user needs to cut off the power supply from the power supply module 2 to the processing module 13; in this case, the processing module 13 may first complete the task processing and data saving and then send a close command to the switch module 14. And, when a lift-up operation of the tact switch 11 is received, it is determined that the tact switch 11 is in the conduction stop state. Correspondingly, the switch module 14 enters the off state according to the off instruction sent by the processing module 13 and the on-off state of the tact switch to disconnect the connection between the power module 2 and the processing module 13, so that the power module 2 does not supply power to the processing module 13 any more, and the processing module 13 enters the off state.
According to the embodiment of the invention, the task processing and data storage are carried out before the processing module 13 enters the shutdown state, so that the processing module 13 can normally work when being powered again, the loss of hardware corresponding to the processing module 13 is reduced, and the service life of the infusion pump is prolonged.
In an optional embodiment of the present invention, the processing module 13 enters the sleep state when it is in the working state and detects that the on-time of the tact switch 11 does not exceed the set time.
In another optional embodiment of the present invention, the processing module 13 enters the operating state when it is in the sleep state and it is detected that the on-time of the tact switch 11 does not exceed the set time.
When the processing module 13 is in the working state, and the pressing operation on the tact switch 11 is received and the pressing time of the tact switch 11 does not exceed the set time, that is, it is detected that the on time of the tact switch 11 does not exceed the set time, the processing module 13 enters the dormant state from the working state, that is, the standby state, and in this case, the infusion pump body connected with the processing module 13 does not execute the corresponding operation any more; when the processing module 13 is required to continue to work, the user presses the tact switch 11 again, and when the pressing operation on the tact switch 11 is received and the pressing time of the tact switch 11 does not exceed the set time, the processing module 13 enters the working state from the dormant state, and can continue to control the infusion pump body connected with the processing module to execute corresponding operation.
The different states of the processing module 13 are distinguished by detecting the conducting time of the tact switch 11, and the processing module 13 is controlled to enter a working state when the conducting time of the tact switch 11 exceeds the set time in the shutdown state; in the working state, when the conducting time of the tact switch 11 exceeds the set time, the control processing module 13 enters the shutdown state; in the working state, when the conducting time of the tact switch 11 does not exceed the set time, the processing module 13 is controlled to enter the dormant state; in the sleep state, when the on-time of the tact switch 11 does not exceed the set time, the processing module 13 is controlled to enter the working state.
The infusion pump control device in the embodiment of the invention can realize different power saving requirements, when the processing module is in a working state, the processing module is powered off after completing the processing of tasks and data by pressing the light touch switch for a long time, thereby realizing zero power consumption during shutdown, saving the electric quantity loss of the power supply module and prolonging the service life of the power supply module. The processing module enters a dormant state by short pressing of the touch switch, under the condition, the infusion pump body connected with the processing module does not execute corresponding operation any more, the electric quantity demand of the processing module is reduced, the electric quantity loss of the power supply module can be reduced to a certain extent, and the processing module can be controlled to enter a working state quickly next time.
In an alternative embodiment of the present invention, the switch module 14 may comprise: a first switching unit 141 and a second switching unit 142.
The first switch unit 141 is respectively connected to the power module 2, the tact switch 11, and the processing module 13, and is configured to establish a connection between the power module 2 and the processing module 13 when the processing module 13 is in a shutdown state and the tact switch 11 is in a conducting state.
The second switch unit 142 is connected to the first switch unit 141 and the processing module 13, and is configured to control the first switch unit 141 to continuously keep an on state according to an on instruction sent by the processing module 13, so as to maintain the connection between the power module 2 and the processing module 13; and under the condition that the tact switch 11 is in the on-stop state, controlling the first switch unit 141 to be closed according to a closing instruction sent by the processing module 13 so as to disconnect the power module 2 from the processing module 13.
The infusion pump control device provided by the embodiment of the invention has the specific working process that:
when the processing module 13 is in the shutdown state, the pressing operation on the tact switch 11 is received, so that the tact switch 11 is in the on state, and the first switch unit 141 is turned on according to the on state of the tact switch 11, thereby establishing the connection between the power module 2 and the processing module 13; after the connection between the power module 2 and the processing module 13 is established, the processing module 13 is in a working state, if the pressing time of the tact switch 11 exceeds the set time, that is, the processing module 13 detects that the on-time of the tact switch 11 exceeds the set time for the first time, the processing module 13 sends a turn-on instruction to the second switch unit 142, and the second switch unit 142 controls the first switch unit 141 to continuously maintain the on-state according to the turn-on instruction, so as to maintain the connection between the power module 2 and the processing module 13, at this time, when the lifting operation of the tact switch 11 is received, the first switch unit 141 still maintains the on-state.
Under the condition that the processing module 13 is in the working state, when the pressing operation on the tact switch 11 is received again, and the pressing time of the tact switch 11 exceeds the set time, the processing module 13 completes task processing and data storage first, and then sends a closing instruction to the second switch unit 142, and the second switch unit 142 is closed according to the closing instruction, but since the tact switch 11 is still in the on state at this time, the second switch unit 142 cannot control the first switch unit 141 to be closed, and when the lifting operation on the tact switch 11 is received, the tact switch 11 is in the on-stop state, at this time, the second switch unit 142 can control the first switch unit 141 to be closed according to the closing instruction, and the connection between the power module 2 and the processing module 13 is disconnected.

Referring to FIG. 5, an exemplary circuit diagram of another infusion pump control device in accordance with an embodiment of the present invention is shown.
In contrast to the infusion pump control apparatus shown in fig. 4, in the infusion pump control apparatus shown in fig. 5, the first switching unit 141 may include: a first field effect transistor Q1 and a second resistor R2; a first end of the second resistor R2 is connected with the power module 2, and a second end of the second resistor R2 is connected with the grid electrode of the first field effect transistor Q1; a first pole of the first fet Q1 is connected to the power module 2 and a second pole of the first fet Q1 is connected to the processing module 13.
The second switching unit 142 may include: a second field effect transistor Q2 and a third resistor R3; the gate of the second field effect transistor Q2 is connected to the processing module 13, the first pole of the second field effect transistor Q2 is connected to the ground GND, and the second pole of the second field effect transistor Q2 is connected to the first switch unit 141; a first end of the third resistor R3 is connected to the processing module 13, and a second end of the third resistor R3 is connected to the ground GND.
Note that the gate of the second field effect transistor Q2 and the first end of the third resistor R3 are both connected to the processing unit in the processing module 13.
The first field effect transistor Q1 may be a P-type field effect transistor, and the second field effect transistor Q2 may be an N-type field effect transistor; the resistance value of the second resistor R2 is larger than 10K omega, and when the resistance value of the second resistor R2 is larger, the power consumption of the infusion pump control device can be reduced.
The operation of the infusion pump control device will now be described with reference to the circuit diagram of fig. 5. When the processing module 13 is in the power-off state, and the tact switch 11 is not pressed, the power module 2 is connected to the gate of the first fet Q1 through the second resistor R2, so that the gate of the first fet Q1 is at a high level, and the first fet Q1 is in the power-off state.
Referring to fig. 6, a flow chart illustrating a working process of an infusion pump control device according to an embodiment of the present invention is shown, which may specifically include the following steps:
601, responding to the pressing operation of a user on the tact switch, and electrifying the power supply module;
603, the power supply module supplies power to the processing module through the first field effect transistor, and the processing module enters a working state;
the user presses the tact switch 11, so that the power module 2 is powered on successfully, when the tact switch 11 is pressed, the tact switch 11 is conducted and grounded, the gate of the first field-effect tube Q1 is changed from a high level to a low level, so that the first field-effect tube Q1 is turned on, so that the connection between the power module 2 and the processing module 13 is established, the power module 2 supplies power to the processing module 13 through the first field-effect tube Q1, and the processing module 13 enters a working state.
The processing unit (e.g. MCU) in the processing module 13 performs the following steps:
605, the processing unit controls the second field effect transistor to be turned on, so as to control the first field effect transistor to be turned on, and the processing module is continuously powered;
the processing unit in the processing module 13 detects whether the on-time of the tact switch 11 exceeds the set time or not through the detection module 12 for the first time, when the on-time exceeds the set time, the processing unit in the processing module 13 inputs a high level signal to the second field effect transistor Q2, the processing unit controls the second field effect transistor Q2 to be turned on, because the first pole of the second field effect transistor Q2 is connected with the ground terminal GND, the gate of the first field effect transistor Q1 is kept at a low level, when the tact switch 11 is pressed, the gate of the first field effect transistor Q1 is still at the low level, the first field effect transistor Q1 is further controlled to be kept at the on state, and the power supply module 2 is continuously controlled to supply power to the processing module 13, that is, the processing module 13 is continuously supplied with power.
When the on-time does not exceed the set time, at this time, the processing unit in the processing module 13 has not input a high level signal to the second fet Q2, and once the lift-up operation of the tact switch 11 is received, the gate of the first fet Q1 changes from the low level to the high level, so that the first fet Q1 is turned off, the power module 2 cannot supply power to the processing module 13 through the first fet Q1, the processing module 13 cannot maintain the working state, and thus enters the off state again, and when power needs to be supplied to the processing module 13 again, the tact switch 11 is pressed again, and the above steps 601 to 603 are performed.
after the processing module 13 enters the sleep state, i.e. after step 607, step 609 is executed;
when the processing module 13 is in the working state, the tact switch 11 is pressed, the processing unit in the processing module 13 detects whether the on-time of the tact switch 11 exceeds the set time through the detection module 12, and when the on-time of the tact switch 11 does not exceed the set time, the processing unit in the processing module 13 controls the processing module 13 to enter the sleep state; when the processing module 13 is in the sleep state, the tact switch 11 is pressed, the processing unit in the processing module 13 detects whether the on-time of the tact switch 11 exceeds the set time through the detection module 12, and when the on-time of the tact switch 11 does not exceed the set time, the processing unit in the processing module 13 controls the processing module 13 to enter the working state. It should be noted that when the processing unit detects that the on-time of the tact switch 11 exceeds the set time in step 609, the processing unit does not perform any processing (i.e., does not control the processing module 13 to enter the working state), or the processing unit executes step 608 and directly controls the second fet Q2 to turn off.
After the processing unit controls the second fet to turn off, i.e., after step 608, step 611 is executed;
and step 612, closing the first field effect transistor, and disconnecting the power supply module from the processing module.
When the processing module 13 is in the operating state, the tact switch 11 is pressed, the processing unit in the processing module 13 detects whether the on-time of the tact switch 11 exceeds the set time again through the detection module 12, when the on-time exceeds the set time, the processing unit in the processing module 13 completes task processing and data storage first, then inputs a low level signal to the second fet Q2 to control the second fet Q2 to turn off, when the press of the tact switch 11 is cancelled again, that is, the lifting operation of the tact switch 11 is detected, so that the gate of the first fet Q1 is at a high level, the first fet Q1 is turned off, and then the power supply from the power module 2 to the processing module 13 is cut off, when the press of the tact switch 11 is not cancelled all the time, that is, that the lifting operation of the tact switch 11 is not detected, the gate of the first fet Q1 is still at a low level, and the second fet Q2 remains off under the control of a low level signal input from the processing unit.
As shown in fig. 4 and 5, the immunity module 15 may include: the anode of the second diode D2 is connected to the switch module 14, and the cathode of the second diode D2 is connected to the detection module 12, 2.
The role of the anti-jamming module 15 is illustrated by way of example in fig. 5: when the second fet Q2 is turned on, the gate of the first fet Q1 is controlled to be kept at a low level, when the second diode D2 is not provided in fig. 5, the first power signal input from the first power terminal VCC in the detection module 12 directly affects the gate voltage of the first fet Q1, when the second diode D2 is provided, the cathode of the second diode D2 is at a high level, the anode of the second diode D2 is connected to the second pole of the second fet Q2 and is at a low level, and the second diode D2 is turned off, so that the detection module 12 does not cause voltage interference to the gate of the first fet Q1.
In the embodiment of the invention, the processing module determines the power supply stopping intention under the condition that the processing module is in a working state and detects that the conducting time of the tact switch is longer than the set time, so that the task and the data are processed according to the power supply stopping intention, and the power of the power supply module is stopped being received after the task and the data are processed; because the processing of the tasks and the data is completed under the condition of power failure, the processing module can normally work when being powered on again, so that the loss of the processing module corresponding to hardware can be reduced, the service life of the infusion pump can be further prolonged, and the condition that the infusion pump cannot normally work to influence the first aid of a patient under an emergency condition can be avoided as much as possible.
