[0002] At present, most medical products are controlled by wired foot pedals. Wired foot pedals require cables, which may cause people to trip during use and are limited by the length of the cables. At the same time, the cables make storage more difficult. Therefore, wireless foot pedal technology is gradually applied to medical products to control the operation or stop of medical equipment, saving the connection cables of the foot switch and making the doctor's operation more efficient.

[0003] The wireless foot pedal device in the current prior art also has some defects: when the wireless foot pedal is powered on, but the medical staff does not actually use the foot pedal to operate the medical equipment, the high-power components in the wireless foot pedal will consume a large amount of power, resulting in high power consumption of the wireless foot pedal and rapid use of the battery power of the wireless foot pedal, which directly causes the problem of short working time of the wireless foot pedal. Therefore, the battery needs to be replaced frequently during use, which seriously affects the normal operation of the equipment or system; the current wireless foot pedal has no low-battery prompt, and the foot pedal function cannot be locked or disabled in low-battery mode. During use, it may be shut down due to low battery, affecting surgery and causing medical accidents. Utility Model Content

[0038] This specification provides method operation steps as described in the embodiments or flow charts, but more or fewer operation steps may be included based on routine or non-creative work. The order of steps listed in the embodiments is only one way of executing the order of many steps and does not represent the only execution order.

[0039] It should be noted that the wireless foot-operated low-power control system of this specification can be used in the field of medical device technology as well as in the field of machinery. This document does not limit the application field of the wireless foot-operated low-power control system.

[0040] In this manual, the medical foot pedal controls the start and stop of related medical equipment through the power of the human foot, thereby assisting doctors to concentrate their hands and vision when operating medical equipment, thereby improving work efficiency and the accuracy of surgery and diagnosis. Wireless foot pedals are widely used in hospital operating rooms, ICUs, CCUs and other places to control medical equipment such as surgical lights, ventilators, implant machines, dental chairs, bone knives, anesthesia machines, nebulizers, trolleys, etc. Through the foot switch, medical staff can operate the equipment more firmly and accurately, especially in high-risk operations, effectively reducing the risk of medical accidents, facilitating medical staff to operate medical equipment more safely and efficiently, and improving the work efficiency and safety of medical institutions.

[0041] Figure 1 The figure shows a schematic diagram of a wireless pedal low power consumption control system according to an embodiment of the present specification, which specifically includes: a pedal control unit 101 , a wireless pedal 102 , a power consumption module 103 and a master control unit 104 .

[0042] The pedal control unit 101 includes: a system input terminal 1011, a battery power supply 1012 and a system output terminal 1013. The system output terminal is connected to the wireless pedal 102. The pedal control unit 101 is used to supply power to the wireless pedal.

[0043] In the embodiment of the present specification, the wireless pedal 102 is connected to the system output terminal 1013 of the pedal control unit 101. In the circuit diagram, the VCC pin on the right side of the MOS tube Q1 can be understood as the system output terminal 1013 of the pedal control unit 101. The wireless pedal 102 is connected to the VCC pin on the right side of the MOS tube Q1, which means it is connected to the system output terminal 1013 of the pedal control unit 101.

[0044] When the system input terminal 1011, the battery power supply 1012 and the system output terminal 1013 of the pedal control unit 101 are turned on, the battery power supply 1012 can supply power to the wireless pedal 102 through the MOS tube Q1 and the system output terminal 1013, and the wireless pedal 102 is in the turned-on state; when any one of the system input terminal 1011, the battery power supply 1012 and the system output terminal 1013 of the pedal control unit 101 is disconnected, the battery power supply 1012 cannot supply power to the wireless pedal 102, and the wireless pedal 102 is in the turned-off state and cannot work normally.

[0045] The wireless foot pedal 102 is electrically connected to the foot pedal control unit 101 and wirelessly connected to the host device 105, and is used to send signals to the host device 105 when in working state. The host device 105 is a medical device, such as: B-ultrasound machine, ventilator, surgical lamp, X-ray machine, etc. The wireless foot pedal sends a signal to the host device 105 when in working state to control the use of the host device 105. When the wireless foot pedal 102 is powered by the battery power supply 1012, it is in a conducting state. In the conducting state, the wireless foot pedal 102 may be in a standby state or in a working state. Furthermore, when the wireless foot pedal is in a working state, it can send wireless signals to medical devices to control the operation of the medical devices and assist doctors in performing surgery or treatment.

[0046] In the embodiment of this specification, the power consumption module 103 is a module inside the wireless pedal 102. The power consumption module 103 is connected to the wireless pedal 102, and includes a first MOS tube and a power consumption component connected to the first MOS tube. When the wireless pedal 102 is in the standby state, the power consumption module 103 is disconnected.

[0047] The main control unit 104 is connected to the status button on the wireless pedal 102. When the status button outputs a valid signal, the main control unit 104 is used to determine that the wireless pedal 102 is in a working state and control the wireless pedal 102 to send a signal to the host device 105; when the status button does not output a valid signal, the main control unit 104 is used to determine that the wireless pedal 102 is in a standby state and control the power consumption module 103 to disconnect. In the embodiment of this specification, the main control unit 104 can be a single-chip microcomputer to control the low-power control system of the wireless pedal 102. Among them, the wireless pedal 102 is provided with at least one key, button or enable end indicating the working state of the wireless pedal 102, and the key, button or enable end is connected to the main control unit 104. When the main control unit 104 detects a valid signal sent by pressing the key, button or enable end, the main control unit 104 can determine that the wireless pedal 102 is currently in a working state, and the main control unit 104 can control the wireless pedal 102 to send a signal to the host device 105. When the main control unit 104 detects that the key, button or enable end does not send a valid signal, the main control unit 104 can determine that the key on the wireless pedal 102 is not triggered or pressed, indicating that the wireless pedal 102 is currently in standby mode and there is no need to send a signal to the host device 105.

[0048] like Figure 2 The figure shows a circuit structure diagram of a pedal control unit according to an embodiment of the present specification. The pedal control unit further includes: a diode 201, a first resistor 202, a Hall switch and a first MOS tube 203. The diode 201, the first resistor 202 and the first MOS tube 203 constitute one of the branches of the pedal control unit. Furthermore, the system input terminal of the pedal control unit is represented as K4_ON in the figure, one end of the system input terminal K4_ON is connected to the output pin of the Hall switch, and the other end of the system input terminal K4_ON is connected to the cathode of the diode 201; the gate-source of the first MOS tube 203 and one end of the first resistor 202 are connected in parallel between the battery power supply and the anode of the diode 201, and the drain of the first MOS tube 203 is connected to the wireless pedal.

[0049] In an embodiment of the present specification, the wireless pedal includes a magnet, the Hall switch outputs a detection signal according to the positional relationship between the wireless pedal and the Hall switch, and the control unit controls the on / off state of the wireless pedal according to the detection signal of the Hall switch.

[0050] Specifically, Figure 3The structure diagram of a Hall switch in an embodiment of the present specification is shown. In the figure, the VCC pin of the Hall switch is connected to the battery power supply, indicating that the battery power supply supplies power to the Hall switch, and the output pin OUT of the Hall switch is connected to the system input terminal, that is, the OUT pin of the Hall switch is connected to the system input terminal K4_ON. When the wireless pedal is stepped on, the distance between the wireless pedal and the Hall switch decreases, the wireless pedal approaches the Hall switch, the Hall switch senses that the magnetic signal reaches the preset threshold, and the output pin outputs a low-level signal; when the wireless pedal is away from the Hall switch, the Hall switch senses that the magnetic signal is less than the preset threshold, and the output pin outputs a high-level signal.

[0051] Specifically, when the Hall switch senses that the wireless pedal is approaching, the OUT pin of the Hall switch outputs a low level, causing the first branch composed of the battery power supply, the first resistor 202 and the diode 201 to be turned on, the gate voltage of the first MOS tube 203 is less than the source voltage, the gate-source voltage of the first MOS tube 203 reaches the turn-on condition, and the first branch of the pedal control unit is turned on. The battery power supply in the pedal control unit can supply power to the wireless pedal through the second MOS tube, and the VCC terminal connected to the wireless pedal outputs a high level.

[0052] When the Hall switch senses that the wireless pedal is moving away, the OUT pin of the Hall switch outputs a high level, causing the first branch to be disconnected, the gate voltage of the first MOS tube is equal to the source voltage, the gate-source voltage does not reach the conduction condition, the first MOS tube is not turned on, and the first branch of the pedal control unit is disconnected. The battery power in the pedal control unit cannot supply power to the wireless pedal through the first MOS tube, and the VCC end connected to the wireless pedal has no output level.

[0053] like Figure 4 Another circuit structure diagram of the wireless pedal low power consumption control system in some embodiments of the present specification is shown. The system further includes: a transistor 204. In the figure, the transistor 204 is marked as Q2. The collector of the transistor is connected to the gate of the second MOS tube, the base of the transistor 204 is connected to the POWER pin of the master control unit, and the emitter of the transistor 204 is grounded.

[0054] When the pedal control unit provides battery power to the wireless pedal, the POWER pin of the master control unit outputs a high level, so that the base of the transistor 204 is driven by the high level of the POWER pin, ensuring that the transistor 204 is turned on, and further ensuring that the second MOS tube is in the on state, thereby ensuring that the wireless pedal is normally powered by the system output end.

[0055] like Figure 5The circuit structure diagram of a power consumption module of an embodiment of the present specification is shown. Among them, the power consumption module 103 includes a second MOS tube and a high-power consumption component connected to the second MOS tube. In the power consumption module, the gate of the second MOS tube is connected to the first switching power supply, and the first switching power supply is controlled by the main control unit. The drain of the second MOS tube is connected to the power consumption component, and is used to provide the first switching power supply to the power consumption component.

[0056] In an embodiment of the present specification, when the wireless pedal is in standby mode, in order to reduce the standby power consumption of the wireless pedal and extend the overall working time of the wireless pedal, the first switching power supply can be controlled to output a higher voltage so that the gate-source voltage of the second MOS tube cannot reach the MOS tube conduction condition, so that power cannot be supplied to the power consumption module, thereby ensuring that the power consumption module is not started in the standby mode of the wireless pedal, thereby reducing the standby power consumption of the wireless pedal.

[0057] like Figure 6 FIG. 1 is a schematic diagram of a circuit structure for dividing a power supply voltage according to an embodiment of the present specification. Figure 6 As shown, it includes: a second resistor R7 and a third resistor R9, the tail end of the second resistor R7 is connected to the head end of the third resistor R9, the second resistor R7 and the third resistor R9 are connected in series, and the head end of the second resistor R7 is connected to the power supply VCC. A battery voltage sampling point is provided at the connection between the tail end of the second resistor R7 and the head end of the third resistor R9 for collecting the battery voltage, and the tail end of the third resistor R9 is grounded. The master control unit is further used to collect voltage from the battery voltage sampling point at the connection between the second resistor R7 and the third resistor R9, and the voltage is the voltage of the battery power supply.

[0058] After collecting the voltage of the battery power source, when the current voltage is less than the first preset voltage, the wireless pedal is controlled to send a low-battery signal to the host device. The low-battery signal can be reflected by a buzzer alarm, wireless pedal vibration, or displaying an alarm sign on the display module of the host device. The wireless pedal sends a low-battery reminder to the host device, which can prompt medical staff to replace the battery when the battery is low, prevent the pedal from being disconnected during use, and achieve the effect of protecting the safety of the surgical process.

[0059] In addition, the main control unit is further used to control the wireless foot pedal to send a signal to the host device to prohibit operation when the current voltage is less than the second preset voltage, suspend the foot pedal function of the host device, and prevent the host device from continuing to operate. It can only be turned on when the battery power is restored; it prevents the foot pedal from being disconnected when the battery is not replaced in time and continues to be used, ensuring the safety of the surgical diagnosis and treatment process.

[0060] In the embodiments of this specification, the value of the first preset voltage can be greater than the value of the second preset voltage. When the battery power voltage is lower than the first preset voltage, a low battery reminder is first issued; when there is no response from the outside and the battery power voltage continues to drop and is lower than the second preset voltage, the main control unit controls the wireless foot pedal to send a signal to the host device to prohibit operation, without external manual intervention, directly controlling the host device to an unusable state, so as to remind personnel to replace the battery in the future and ensure the safety of the surgical medical process. In this specification, the specific values ​​of the first preset voltage and the second preset voltage are not limited.

[0061] In the embodiment of the present specification, at least one status button or enabling terminal related to the working state of the wireless foot pedal is set on the wireless foot pedal. When the wireless foot pedal is electrically conductive, the wireless foot pedal is in a standby state. When the medical staff presses or triggers the button related to the working state on the wireless foot pedal, the wireless foot pedal officially enters the working state and can send a wireless signal to the host device.

[0062] At the same time, a pin of the master control unit is electrically connected to the button of the wireless pedal related to the working state, and the master control unit detects the signal output by the button, that is, the master control unit determines the working state of the wireless pedal according to the signal output by the button of the wireless pedal. For example, when the wireless pedal is turned on and powered on, no medical staff presses or triggers the button on the wireless pedal related to the working state of the wireless pedal, and the status button of the wireless pedal outputs a signal of "100". The master control unit determines that the wireless pedal is in the standby state according to the signal output by the status button of the wireless pedal, and further controls the functional module to be disconnected, so as to keep the wireless pedal in a low power consumption state in the standby state, thereby extending the standby time of the wireless pedal.

[0063] When the wireless foot pedal is in standby mode, a medical staff member presses or triggers the button related to the working state of the wireless foot pedal, and the status button of the wireless foot pedal outputs a signal of "101". The main control unit determines that the wireless foot pedal is in working state according to the signal output by the status button of the wireless foot pedal. The function module can be further controlled to be turned on, and the wireless foot pedal sends a wireless signal to the host device.

[0064] In the embodiment of the present specification, there are multiple buttons (for example, button A and button B) related to the working status of the wireless foot pedal, and the main control unit is electrically connected to the multiple buttons. When the wireless foot pedal is turned on and powered on, and no medical staff presses or triggers the button, the output signal of each status button on the wireless foot pedal is "100", and the main control unit determines that the wireless foot pedal is in standby mode based on the signal output by the status button of the wireless foot pedal. The function module is further controlled to be disconnected, so as to keep the wireless foot pedal running in a low power consumption state in the standby state, thereby extending the standby time of the wireless foot pedal.

[0065] When a medical staff member presses or triggers button A, the status button of the wireless pedal outputs a signal of "101", and when a medical staff member presses or triggers button B, the status button of the wireless pedal outputs a signal of "110". The master control unit determines that the wireless pedal is in working state according to the signal output by the status button of the wireless pedal. The function module can be further controlled to be powered on, and the wireless pedal can be controlled to send a wireless signal to the host device.
