[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] like Figure 1-2 As shown, a remote control device for medical equipment includes a signal transmitting mechanism and a signal receiving mechanism, wherein the signal transmitting mechanism and the signal receiving mechanism are wirelessly connected.

[0017] The signal transmitting mechanism includes a wireless signal transmitting module and several foot pedals, and the signal receiving mechanism includes a wireless signal receiving module and several signal transmission units. The number of signal transmission units is the same as the number of foot pedals, and the wireless signal transmitting module is wirelessly connected to the wireless signal receiving module.

[0018] The wireless signal transmitting module is model STX885. The foot pedal is connected to the data input terminal of the wireless signal transmitting module. Pin 1 of the wireless signal transmitting module is connected to an external power supply. Pin 2 of the wireless signal transmitting module is grounded. Pin 9 of the wireless signal transmitting module is grounded for radio frequency. Pin 10 of the wireless signal transmitting module is connected to an external antenna.

[0019] The wireless signal receiving module is model SRX885. The signal transmission unit includes a relay and a plug 1. The relay is model G3VM-61VY3. The plug 1 is connected to the source and drain of the wireless signal receiving module. Pin 2 of the relay is grounded. Pin 1 of the relay is connected to the parallel data terminal of the wireless signal receiving module. Pin 1 of the wireless signal receiving module is connected to an external power supply. Pin 2 of the wireless signal receiving module is grounded. Pin 9 of the wireless signal receiving module is connected to an external antenna.

[0022] The G3VM-61VY3 relay is a solid-state relay. Its input side uses an optocoupler LED, which only requires a 5-50mA forward current. There is no need to consider the voltage matching problem of the original drive circuit. The output side is bidirectional and has no mechanical contacts, so the polarity of the original load circuit can be completely ignored.

[0023] This solid-state relay completely cuts off the electrical interference of the original foot pedal circuit to the load through optocoupler isolation.

[0024] Furthermore, its output source and drain can directly replace the original relay contacts without needing to distinguish polarity.

[0025] Plug 1 here is plugged into the medical device and electrically connected to it.

[0026] Foot pedal 2 acts as a contact switch, and its opening or closing enables the switching function to be turned on or off.

[0027] When foot pedal 2 is pressed, a "closed" control signal is fed back to the wireless signal transmitting module. The wireless signal transmitting module transmits the control signal to the wireless signal receiving module through the antenna. The wireless signal receiving module sends the control signal to the relay. According to the preset control logic, the relay adjusts the switch state and then outputs a switch control signal to the medical device, thereby realizing remote control of the medical device.

[0028] Compared with existing technologies, this remote control device for medical equipment uses a MOSFET output solid-state relay with optocoupler isolation function. With the cooperation of the STR885 wireless signal transmitting module and the SRX885 wireless signal receiving module, it can control the connection and disconnection of external loads. Moreover, the relay does not need to consider the voltage matching problem of the original drive circuit, and has bidirectional conduction without mechanical contacts, which improves adaptability and compatibility and enhances practical value.
