[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present invention are used to distinguish different objects, rather than to limit a specific order. The following embodiments of the present invention can be implemented separately, or in combination with each other, and the embodiments of the present invention do not impose specific limitations on this.

[0039] Figure 1 This is a structural diagram of a perfusion pump controller provided by an embodiment of the present invention.

[0040] As Figure 1 shown, the perfusion pump controller 10 is disposed inside the perfusion pump 100 to be controlled, and the power supply unit 20 of the perfusion pump 100 to be controlled is electrically connected to the associated control device 200; the perfusion pump controller 10 includes a signal recognition device 11.

[0041] The signal recognition device 11 is disposed on the power connection line between the power supply unit 20 of the perfusion pump 100 to be controlled and the associated control device 200.

[0042] The signal recognition device 11 is configured to recognize the start signal of the associated control device 200, and generate a linkage start signal based on the start signal, so that the perfusion pump 100 to be controlled is started and standby based on the linkage start signal.

[0043] Specifically, the associated control device 200 is connected to the power supply unit 20 of the perfusion pump 100 to be controlled. The power connection line between the associated control device 200 and the power supply unit 20 includes a positive connection line A+ and a negative connection line A-. The signal recognition device 11 is connected in series on the positive connection line A+ between the associated control device 200 and the power supply unit 20. When the associated control device 200 starts to power on, current will flow through the positive connection line A+. The signal recognition device 11 generates a linkage start signal by recognizing the current flowing through, that is, by recognizing the start signal of the associated control device 200. The perfusion pump 100 to be controlled is started and standby based on the generated linkage start signal, realizing the linkage start between the perfusion pump 100 to be controlled and the associated control device 200.

[0044] Exemplarily, the associated control device 200 can be a shaver for endoscopic surgery, or other devices such as a plasma device that are connected to the perfusion pump and need to be started in linkage with the perfusion pump.

[0045] In the embodiment of the present invention, there is no need to set a foot control line, and manual foot stepping is not required to cooperate with the linkage between the perfusion pump and the associated control device. It is also not necessary to pay attention to whether the foot line sequence settings between the perfusion pump and the associated control device are compatible. It only needs to connect the power supply unit of the perfusion pump to the associated control device, supply power to the associated control device using the power supply of the perfusion pump, and set a signal recognition device on the positive connection line between the two to achieve the linkage between any two perfusion pumps and the associated control device.

[0046] The present invention arranges a signal recognition device on the power connection line between the power supply unit of the perfusion pump to be controlled and the joint control device, identifies the start signal of the joint control device when the joint control device is powered on, and controls the linkage start of the perfusion pump to be controlled based on the recognized start signal, thereby solving the technical problem of poor adaptability of the perfusion pump that exists when linkage control between any perfusion pump and the planer can only be achieved by a foot control line with a set foot line sequence, and achieves the technical effect that any two perfusion pumps and the joint control device can be started in linkage, thereby expanding the adaptability of the perfusion pump.

[0047] Alternatively, if Figure 1 As shown, the perfusion pump controller 10 further includes a control unit 12;

[0048] The control unit 12 is electrically connected to the signal recognition device 11; the control unit 11 is electrically connected to the power supply unit 20;

[0049] The control unit 12 is used to receive the linkage start signal generated by the signal recognition device 11, and control the controlled perfusion pump 100 to start and standby based on the linkage start signal, thereby realizing the linkage start between the controlled perfusion pump 100 and the joint control device 200.

[0050] Specifically, the control unit 12 is arranged in the perfusion pump controller 10, and is used to control the perfusion pump 100 to perform corresponding actions, and is also used to receive the linkage start signal generated by the signal recognition device 11 to control the start of the perfusion pump 100 to be controlled based on the linkage start signal.

[0051] Figure 2 It is a circuit diagram of a signal recognition device provided by an embodiment of the present invention.

[0052] Alternatively, if Figure 2 As shown, the signal recognition device 11 includes a current sensor T1 and an operational amplifier U1; the current sensor T1 includes a sensing wire L1 and an sensing coil L2.

[0053] The induction wire L1 is connected in series to the positive connection line A+ of the power connection line between the power supply unit 20 and the joint control device 200; the induction coil L2 is electrically connected to the control unit 12 via the operational amplifier U1.

[0054] Specifically, according to Faraday's law of electromagnetic induction, when the current in a conductor changes, an induced electromotive force is generated around it. The current sensor usually contains a ring-shaped iron core. When the measured current passes through this ring-shaped iron core, a changing magnetic field is generated around the iron core. This changing magnetic field induces an electromotive force. By measuring the magnitude of this induced electromotive force, the magnitude of the measured current can be inferred.

[0055] Based on the above principle, a current sensor T1 is provided in the signal recognition device 11. The current sensor T1 is connected in series to the positive connection line A+ of the power connection line between the power supply unit 20 of the perfusion pump 100 to be controlled and the associated control device 200. Taking the shaver of the endoscopic surgery as an example of the associated control device 200, when the shaver is powered on and started, the induction wire L1 will recognize the current change in the positive connection line A+. The induced electromotive force of the induction coil L2 will increase. The operational amplifier U1, as a sampling circuit, obtains the signal of the increased electromotive force of the induction coil L2 (i.e., the start signal of the above-mentioned associated control device 200), and outputs a level signal (i.e., the above-mentioned linkage start signal) to the control unit 12. After receiving this level signal, the control unit 12 controls the perfusion pump 100 to be controlled to operate automatically, achieving the technical effect of linked start.

[0056] The operational amplifier U1 can adopt LM358. LM358 is a differential amplifier circuit that can amplify a tiny voltage and output a proportional voltage signal.

[0057] Optionally, as Figure 2 shown, the signal recognition device 11 further includes a shunt unit 111;

[0058] The shunt unit 111 is arranged between the induction coil L2 and the operational amplifier U1; the shunt unit 111 is used to shunt the current induced by the induction coil L2.

[0059] Specifically, the shunt unit 111 is used to shunt the current induced by the induction coil L2, thereby generating a voltage drop proportional to the current.

[0060] Optionally, as Figure 2 shown, the shunt unit 111 includes a first resistor R1 and a second resistor R2;

[0061] The first end of the first resistor R1 is electrically connected to the first end of the induction coil L2, and the second end of the first resistor R1 is electrically connected to the second end of the induction coil L2;

[0062] The first end of the second resistor R2 is electrically connected to the second end of the first resistor R1, and the second end of the second resistor R2 is grounded to GND.

[0063] Specifically, after the induction coil L2 generates an induced electromotive force and outputs a current, through the shunt resistors R1 and R2, a voltage drop proportional to the current is generated, and this voltage drop value can be calculated according to Ohm's law.

[0064] Optionally, as Figure 2 shown, the signal recognition device 11 further includes a filtering unit 112; the filtering unit 112 is arranged between the induction coil L2 and the operational amplifier U1;

[0065] The filtering unit 112 is used to filter high-frequency noise from the electrical signal transmitted by the induction coil L2 to the operational amplifier U1.

[0066] Optionally, as Figure 2 shown, the filtering unit 112 includes a filtering capacitor C1:

[0067] The filtering capacitor C1 is arranged between the induction coil L2 and the negative input terminal 2 of the operational amplifier U1. The output terminal 1 of the operational amplifier U1 is electrically connected to the control unit 12, the positive input terminal 3 of the operational amplifier U1 is electrically connected to the second terminal of the induction coil L2, the power supply terminal 4 of the operational amplifier U1 is electrically connected to the power supply VCC, and the ground terminal 5 of the operational amplifier U1 is grounded to GND.

[0068] Specifically, the filtering capacitor C1 is used to filter high-frequency noise in the signal to ensure stable output of the identified start signal.

[0069] In the embodiment of the invention, through the setting of the signal recognition device, the selection range of the linked control device is expanded, not limited to devices such as plasma and planer. In fact, all scenarios where a perfusion pump needs to be used in conjunction with other devices can be applied; using a current sensor as the signal recognition device, it has high sampling accuracy and precise control, effectively improving the linked control accuracy; all components of the signal recognition device are common standard parts, with low production costs, and realizing the linked start control of the perfusion pump and the required linked devices without adding much cost.
