[0025] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the application, and are not used to limit the application.

[0026] In order to better understand the technical solutions of the application, the following will be described in detail in conjunction with the drawings and specific embodiments of the specification.

[0027] In the clinical work in the hospital, it is easy to occur that blood and body fluid are splashed on the floor or sprayed on the surface of objects in operating rooms, emergency rooms, ICUs and other departments. At present, many medical devices are controlled by foot switches or manual switches to output energy of the devices, such as common high-frequency electrotomes, laser therapy instruments, radiofrequency therapy instruments and the like.

[0028] When liquid such as blood and body fluid invades into the foot switch or manual switch through splashing or spraying, it will cause unexpected energy output or misoperation due to misoperation triggering, and cause unexpected damage to the human body or public property.

[0029] In the prior art, waterproof and dirt-proof designs are generally selected for the foot switch and the manual switch. For example, a sealing material is used to wrap the inside of the switch to ensure that even if liquid splashes on the switch, it will not penetrate into the internal circuit; or an emergency stop mechanism is added: an emergency stop button is added to the medical device, and once the device is mis-triggered, medical staff can quickly press the button to cut off the energy output to prevent damage from spreading; or an intelligent sensor is introduced to monitor the humidity or liquid existence around the switch. Once an abnormality is detected, the system should immediately issue an alarm and automatically cut off the power supply of the device to prevent misoperation.

[0030] However, in actual operation, there are always unavoidable situations for waterproof and dirt-proof designs, and for the emergency stop mechanism and the intelligent sensor, they are a reminder after the occurrence, and the controller has already triggered the medical device, so there is still a high risk.

[0031] Based on this, the application provides a driving signal output circuit to solve the technical problem of mis-triggering of the switch of the existing medical device in clinical work. Please refer to Figure 1 , Figure 1 The structural block diagram provided by the embodiment of the driving signal output circuit of the application.

[0032] In this embodiment, the driving signal output circuit comprises a driving detection module 10, a comparison module 20 and a signal output module 30. The driving detection module 10 is connected to the comparison module 20, and the comparison module 20 is further connected to the signal output module 30.

[0033] It should be noted that the driving detection module 10 is used to detect the state of the driving switch and output a detection signal to the comparison module 20 when the driving switch is closed.

[0034] It can be understood that the driving detection module 10 can contain one or more sensors or detection circuits for monitoring the closing or opening state of the driving switch (which can be a foot switch, a manual switch or the like). When the driving switch is closed, the detection module will detect the change and output a detection signal.

[0035] It can be understood that the driving switch can be part of the driving detection module 10, and the change of the state of the driving switch itself can cause the change of the internal circuit of the driving detection module 10, and different detection signals can be output.

[0036] It can be understood that the state of the driving switch generally includes a zero-resistance on state and an off state; but when the liquid such as blood or body fluid invades into the driving switch by splashing or spattering, the driving switch will also be on, but the resistance value of the blood or body fluid will be presented at this time, and the driving switch can be considered to be in a false on state at this time.

[0037] It can be understood that based on the above-mentioned circuit, the reason for the change of the resistance value can be that the detection signal can be a resistance value signal, or a voltage, current or other form of electrical signal based on the change of the resistance value, which is used to represent the state of the driving switch. In the present scheme, the change of the resistance value of the driving switch will cause the change of the overall resistance value of the circuit, and the detection signal represents this change.

[0038] In order to enable the signal output module 30 to judge the state of the driving switch based on the detection signal, the present embodiment introduces a comparison module 20. It should be noted that the comparison module 20 is used to determine that the driving switch is on when the detection signal is in a preset range, and the signal output module 30 outputs a driving signal.

[0039] It can be understood that based on the above-mentioned function, the comparison module 20 can be implemented by a single-chip microcomputer MCU, an operational amplifier circuit, a programmable logic device CPLD, an FPGA or a comparator.

[0040] It can be understood that the comparison module 20 first receives the detection signal from the driving detection module 10. This signal represents the current state of the driving switch, such as closing, opening or false on. Next, the comparison module 20 compares the received detection signal with one or more preset thresholds or ranges, i.e. a preset range.

[0041] Further, based on the fact that the detection signal can be a resistance, voltage, current or other form of electrical signal, the preset range can be a preset resistance range, a preset voltage range, a preset current range or a range of other forms of electrical signals. The preset range can be calculated according to system requirements, electrical characteristics of the driving switch and safety standards.

[0042] It can be understood that if the detection signal is in the preset range, the comparison module 20 will determine that the driving switch is on. Subsequently, it will send a control signal to the signal output module 30, instructing it to output a driving signal to drive the medical device. Conversely, if the detection signal is not in the preset range, the comparison module 20 will not trigger the signal output module 30, thereby avoiding unintended energy output or misoperation.

[0043] In the embodiment, the driving detection module outputs corresponding detection signals based on the difference in circuit characteristics between false triggering and normal triggering; the comparison module determines whether the detection signals are within a preset range to confirm whether the driving switch is closed or not, and the control signal output module stops outputting the driving signal when the switch is not closed, thereby avoiding false triggering.

[0044] On the basis of the above embodiment, the application provides a specific implementation mode, please refer to Figure 2 , Figure 2 The circuit diagram of the implementation mode provided by the driving signal output circuit embodiment of the application.

[0045] In the implementation mode, the voltage signal is selected as the detection signal by constructing a voltage dividing circuit to represent the change in loop resistance, and the driving detection module 10 comprises a first diode D1, a first resistor R1, a second resistor R2 and a driving switch SW1; the anode and cathode of the first diode D1 are respectively connected to a working power supply and the first end of the first resistor R1; the second end of the first resistor R1 is connected to the first end of the driving switch SW1; the second end of the driving switch SW1 is connected to the first end of the second resistor R2 and the first input end of the comparison module 20; and the second end of the second resistor R2 is grounded.

[0046] It should be noted that the first diode D1 functions as a unidirectional conductor, which allows current to flow from the anode (positive electrode) to the cathode (negative electrode) but prevents reverse current to prevent the foot switch from being mistakenly connected to other power supplies and causing impact on the working power supply. The first resistor R1 is used to limit current to protect other components in the circuit from damage caused by excessive current. At the same time, it, together with the diode D1, constitutes a simple power protection circuit.

[0047] It should be noted that the driving switch SW1 is a key component in the circuit, which is used to control the on-off of the circuit. When the driving switch SW1 is closed, the circuit forms a path; when the SW1 is disconnected, the circuit is cut off. The second resistor R2 functions as a voltage divider here, which, together with the driving switch SW1, forms a voltage dividing circuit. At this time, the connection between the first end of the second resistor R2 and the second end of the driving switch SW1 can be used as a voltage sampling point. When the driving switch SW1 is closed, the second resistor R2 is connected in series with the first resistor R1 through the driving switch SW1, and the voltage at the voltage sampling point is the voltage at the first input end of the comparison module 20.

[0048] It can be understood that the voltage dividing sampling point refers to reducing a higher voltage signal to a lower voltage signal suitable for subsequent circuit processing by means of resistance voltage division in the circuit, and sampling on this reduced voltage signal. The voltage dividing sampling point is usually used in the case where it is necessary to convert a high voltage signal into a low voltage signal for processing by other electronic devices. The signal change through the voltage dividing sampling point can represent the change of the loop resistance value, and at the same time, the working condition of the comparison module 20 is reduced.

[0049] It can be understood that when the second resistance R2 and the first resistance R1 are selected, due to the false conduction false trigger, the blood has the resistance characteristic voltage division, resulting in the decrease of the second resistance R2 voltage division, and thus the voltage at the first input end of the comparison module 20 when the zero resistance is turned on is greater than the voltage when the false conduction is turned on.

[0050] In the embodiment, the comparison module 20 comprises: a comparator; the first input end of the comparator is connected to the voltage dividing sampling point; the second input end of the comparator inputs a reference voltage to generate the preset range; and the output end of the comparator is connected to the signal output module 30.

[0051] It can be understood that the comparator is an analog circuit component for comparing the voltage output by the drive detection module 10 (through the second resistance R2) with the preset reference voltage. The first input end is connected to the first end of the second resistance R2, that is, the second end of the drive switch SW1. When the drive switch SW1 is closed, this input end will receive a voltage obtained by R1 and R2 voltage division. The second input end inputs a reference voltage, and at this time the reference voltage determines the preset range. The reference voltage can be generated by a voltage stabilizer, a voltage dividing circuit or other means. The high level output by the comparator when the detection signal is lower than the reference voltage is different from the low level output by the comparator when the detection signal is higher than the reference voltage, and based on this difference, the signal output module can be designed.

[0052] The drive signal output circuit further comprises: a reference voltage module; the reference voltage module is connected to the second input end of the comparator; and the reference voltage module is used to provide a reference voltage to the comparator to generate the preset range. It can be understood that integrating the reference voltage into the drive signal output circuit can share the same working power supply, and the circuit is optimized.

[0053] Specifically, the reference voltage module can include a third resistor R3 and a fourth resistor R4; a first end of the third resistor R3 is connected to the working power supply; a second end of the third resistor R3 is connected to a first end of the fourth resistor R4 and a second input end of the comparator; and a second end of the fourth resistor R4 is grounded. The two resistors together constitute a voltage dividing circuit for generating a stable reference voltage from the working power supply. This reference voltage is an important reference for the voltage comparison of the comparator.

[0054] In the embodiment, the signal output module 30 includes a fifth resistor R5; a first end of the fifth resistor R5 is connected to the working power supply; and a second end of the fifth resistor R5 is connected to an output end of the comparator and an external control device. It can be understood that the fifth resistor R5 is a pull-up resistor, and when the comparator outputs a low-level signal, the working power supply outputs a driving signal through the fifth resistor R5.

[0055] It can be understood that when the voltage at the first input end is less than the voltage at the second input end, i.e., the reference voltage, the driving switch is in a false conduction state, the comparator outputs a high-level signal to the signal output module, and the signal output module cannot drive the controller of the external device; when the voltage at the first input end is greater than the voltage at the second input end, i.e., the reference voltage, the driving switch is in a zero-resistance conduction state, the comparator outputs a low-level signal to the signal output module, and the signal output module drives the controller of the external device, thereby achieving the output of the driving signal.

[0056] Further, due to the possible reasons of circuit aging or different splashing liquids, the above-mentioned embodiment may not be accurate in the detection of false triggering due to the selection of the resistance values of the second resistor R2 and the first resistor R1. Therefore, based on the above-mentioned embodiment, the present application proposes another embodiment, which is described below with reference to Figure 3 , Figure 3 The circuit diagram of another embodiment of the driving signal output circuit provided by the present application is shown in FIG. 4.

[0057] In the embodiment, the driving signal output circuit further includes a calibration module; and the driving detection module 10 is connected to the comparison module 20 through the calibration module.

[0058] It can be understood that the calibration module is an additional circuit component or functional module, and its main function is to receive the detection signal from the driving detection module 10 and calibrate or adjust the detection signal according to the comparison result generated by the comparison module 20. The detection error caused by circuit aging, component parameter change or external interference (such as resistance change caused by splashing liquid) is eliminated or reduced. Thus, the accuracy and reliability of the driving signal output circuit are improved, and the possibility of false triggering is reduced.

[0059] Specifically, the calibration module can monitor the output of the comparison module 20, and when it finds that the comparison result does not match the expectation (for example, frequent false triggering or non-triggering), it can adjust the processing method of the detection signal.

[0060] Specifically, the calibration module can contain programmable elements (such as digital potentiometers, analog switches, etc.), which can dynamically adjust resistance values, capacitance values, or other circuit parameters according to a preset algorithm or logic, thereby achieving calibration of the detection signal.

[0061] Specifically, the calibration module can include an adjustable resistance VR1, a first end of the adjustable resistance VR1 connected to the drive detection module 10 and the comparison module 20, and a second end of the adjustable resistance VR1 grounded. At this time, the second resistance R2 can be preposed for a protection circuit, with a first end connected to a second end of the drive switch SW1; a second end of the second resistance R2 connected to a first end of the adjustable resistance VR1; a first input end of the comparator also connected to the first end of the adjustable resistance VR1; and a second end of the adjustable resistance VR1 grounded.

[0062] It can be understood that in this embodiment, the second resistance R2 is not used for voltage division, but the adjustable resistance VR1 is used for voltage division to protect the comparator from impact. At this time, the second end of the second resistance is connected to the first end of the adjustable resistance as a voltage division sampling point, and the first input end of the comparator is connected to the voltage division sampling point, and the remaining connection relationship is the same as that of the previous embodiment.

[0063] It can be understood that when the false triggering judgment is found to be inaccurate, the adjustable resistance VR1 can be changed to distinguish the false conduction state from the zero resistance conduction state, thereby avoiding the situation where the detection signal in the false conduction state falls within the preset range due to changes in the loop resistance caused by circuit aging or external factors, resulting in false triggering, without the need to disassemble the entire circuit.

[0064] Further, the drive signal output circuit can further include a filtering module, which is connected to the drive detection module 10, the comparison module 20, the reference voltage module, the signal output module 30, and the calibration module, respectively, for filtering out noise and static electricity in the drive signal output circuit.

[0065] The filter module comprises a first capacitor C1, a second capacitor C2, a third capacitor C3, a fourth capacitor C4 and an ESD diode D2; a first end of the first capacitor C1 is connected to an anode of the first diode D1, and a second end of the first capacitor C1 is grounded; a first end of the second capacitor C2 is connected to a working power supply, and a second end of the second capacitor C2 is grounded; a first end of the third capacitor C3 is connected to a first end of the fourth resistor R4, and a second end of the third capacitor C3 is grounded; a first end of the fourth capacitor C4 is connected to a first end of the adjustable resistor VR1, and a second end of the fourth capacitor C4 is grounded; an anode of the ESD diode D2 is connected to a second end of the driving switch, and a cathode of the ESD diode D2 is grounded.

[0066] It can be understood that the first capacitor C1 is connected between the anode of the first diode D1 and the ground, for filtering out high-frequency noise introduced from the power input end. The second capacitor C2 is connected between the working power supply and the ground, as a bypass capacitor, for further filtering out high-frequency noise in the power supply. The third capacitor C3 is connected between the first end of the fourth resistor R4 (i.e. the second input end of the comparator) and the ground, for filtering out high-frequency interference at the input end of the comparator. The fourth capacitor C4 is connected between the first end of the adjustable resistor VR1 (i.e. the first input end of the comparator) and the ground, for filtering out high-frequency noise and electrostatic interference at the input end. The ESD diode D2 is connected between the second end of the driving switch and the ground, as an electrostatic discharge (ESD) protection element, for preventing static electricity from damaging the circuit.

[0067] In the embodiment, by introducing the adjustable resistor VR1 as part of the calibration module and reasonably utilizing the second resistor R2 for protection, accurate calibration and adjustment of the driving signal output circuit can be achieved, the accuracy and reliability of the circuit are improved, and the problem of false triggering caused by circuit aging or external interference is reduced.

[0068] The application also provides a medical device having the driving signal output circuit as described above.

[0069] The medical device provided by the application adopts the driving signal output circuit in the above embodiment, and can solve the technical problem of false triggering of the switch of the existing medical device in clinical work.
