Abstract
Description
Technical Field
[0001] This utility model relates to a foot switch and belongs to the field of medical device technology. Background Technology
[0002] With the continuous advancement of medical technology, the automation and intelligence of medical equipment are increasing, leading to higher demands for ease of operation and safety. Medical foot switches, as crucial components for human-machine interaction in medical equipment, allow medical staff to control the equipment's operation and function switching via their feet during surgery, examinations, and treatments. This significantly improves work efficiency while avoiding the risk of cross-infection that might arise from hand operation.
[0003] Currently, over 90% of medical equipment uses generic foot switches, which present identification difficulties: identical colored casings, standardized pedal structures, and lack of differentiated functional markings. Statistics from a top-tier hospital show that the monthly incidence of equipment malfunctions due to accidental foot switch activation in the emergency department reaches 12.7%, with 78% of these cases stemming from visual confusion. Traditional foot switches use cable transmission, resulting in overlapping and crisscrossing cables from multiple devices, creating "cable spheres of influence" centered on each device. This forces the minimum distance between devices to increase to 1.5 meters (the standard requires ≥0.8 meters), reducing the usable area of the treatment room. The overlapping cables also require medical staff to cross multiple times during movement, increasing the risk of stumbles and sharps injuries. Furthermore, foot switch cables can easily block emergency exits. The connecting wires of multiple foot switches are also prone to tangling and mess, making storage and cleaning inconvenient for operators. Therefore, this utility model is proposed. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a multifunctional foot switch.
[0005] The technical solution of this utility model is as follows:
[0006] A multifunctional foot switch includes a pedal assembly and a base plate assembly. The base plate assembly includes a base plate, a sealing cover, a foot socket, a splitter, a power module, and a control module. The foot socket, splitter, power module, and control module are disposed on the underside of the base plate. The foot socket, splitter, and power module are all connected to the control module. The sealing cover is disposed on the underside of the base plate to protect the internal structure.
[0007] The pedal assembly includes a rubber housing, an upper housing, a lower housing, contact plates, springs, connecting cables, and a pressure plate. Springs are evenly distributed on the lower housing. Contact plates are respectively provided on the upper and lower housings. The upper and lower housings are arranged inside the rubber housing with the contact plates facing each other. The springs are used to support the upper and lower housings. A pressure plate is fixed to the lower side of the lower housing by bolts. The contact plates are connected to a splitter through the connecting cables. A protective coil is provided at the position where the connecting cables pass through the pressure plate to protect the connecting cables. Several pedal assemblies are set on the upper side of the base plate through the pressure plate.
[0008] According to a preferred embodiment of this utility model, a limiting ball is provided in the middle of the upper side of the lower shell through a threaded screw, and a limiting groove corresponding to the limiting ball is provided in the upper shell to limit the descent distance of the upper shell and prevent the operator from damaging the equipment by applying excessive force.
[0009] According to a preferred embodiment of the present invention, the pedal assembly is provided with at least two pedals.
[0010] According to a preferred embodiment of the present invention, a guide groove is provided on the base plate, and the pressure plate is fixed to the base plate by bolts. Except for the side pedal assembly, the connecting bolts between the pressure plate of the remaining pedal assembly and the base plate are provided in the guide groove. The position of the pedal assembly can be adjusted by moving the position of the bolts, thereby adapting to the foot adjustment habits of different people and reducing the frequency of accidental stepping.
[0011] According to a preferred embodiment of the present invention, the power module includes a battery compartment and a battery. The battery compartment is fixed to the base plate, and the battery is installed inside the battery compartment through a sealing ring. The battery is connected to a control module through a power supply cable.
[0012] According to a preferred embodiment of the present invention, the control module is also connected to a Bluetooth module.
[0013] The steps for using the above-mentioned multi-functional foot switch are as follows:
[0014] Depending on the actual situation of the medical equipment, choose either a wired connection or a wireless connection. When using a wired connection, connect each medical device through the foot socket. When using a wireless connection, connect each medical device through the Bluetooth module. During operation, the control module continuously outputs a high-level electrical signal to the signal circuit of each pedal assembly and monitors in real time whether there is a high-level signal return. When the pedal assembly is not pressed, the two contact pieces are not short-circuited, the signal transmission circuit is in an open circuit state, the control module does not detect the return of a high-level signal, and the pedal switch is in a standby state.
[0015] When the pedal is pressed, the contact points of the upper and lower shells are short-circuited, and the signal circuit is in a short-circuit state. The control module detects the return of a high-level signal and immediately sends a signal, and the relevant medical equipment performs the corresponding operation. When the pedal is released, the control module detects the disappearance of the high-level signal, immediately stops sending signals, and the pedal switch returns to the standby state.
[0016] The beneficial effects of this utility model are as follows:
[0017] The pedal assembly of this invention is adjustable in position to accommodate different people's foot adjustment habits, reducing the frequency of accidental stepping. Moreover, this invention uses a single foot switch to control multiple medical devices, providing both wired and wireless transmission modes. This solves the problem of unreasonable equipment layout and small usable area in treatment rooms. Furthermore, the wireless transmission mode allows for overall sterilization through disinfection, avoiding cables passing through sterile areas and reducing the postoperative incision infection rate.
