Description

Technical Field

[0001] This invention belongs to the field of switch technology, and in particular relates to a defibrillator with a remote control switch device. Background Technology

[0002] A defibrillator is a medical device that uses a strong pulse of electrical current to eliminate arrhythmias and restore sinus rhythm. It is a crucial emergency medical device. Clinically, defibrillators are key devices for correcting arrhythmias and restoring normal heart rhythm. The defibrillator's pulse of electrical current is usually triggered by pressing a switch button. This switch button is typically connected to a push-button switch, which in turn triggers the pulse of electrical current. Medical personnel must directly press the charging and discharging buttons on the device to complete the charging and discharging process. However, this method of operation presents some inconveniences in practice. For example, during surgery, when charging or discharging the defibrillator is required, medical personnel need to leave their current work position and run to the device. Ventricular fibrillation is one of the most fatal arrhythmias, and every second counts in resuscitation. The current method of operation wastes valuable time, and frequent movement during emergency resuscitation can interfere with the surgery, increasing surgical risks. In addition, in special environments or scenarios where there is a high risk of radiation or infection, medical staff may face health risks if they directly handle defibrillators. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies and provide a defibrillator with a remote control switch device. By controlling the movement and pressing operation of the finger robot, the charging and discharging of the defibrillator can be remotely controlled, which greatly shortens the operation time and saves precious treatment time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a defibrillator with a remote control switch device, comprising a defibrillator, wherein the switch position of the defibrillator is provided with a remote control switch mechanism, the remote control switch mechanism comprising a fixing mechanism, a moving mechanism, a clamping mechanism and a finger robot, the moving mechanism being connected to the fixing mechanism, the moving mechanism comprising a Π-shaped bracket, a remote control motor, a lead screw transmission pair and a moving support plate, the upper surface of the Π-shaped bracket being fixedly connected to the remote control motor via a support frame, the output end of the remote control motor being connected to the lead screw via a connecting flange, the lead screw being screwed to a sliding sleeve, the sliding sleeve being fixedly connected to the moving support plate, a guide post and guide sleeve being provided between the moving support plate and the upper surface of the Π-shaped bracket, constituting a lifting mechanism of the moving mechanism of the lead screw transmission pair, the clamping mechanism being fixedly connected to the moving support plate, the clamping mechanism being fixedly connected to the finger robot, the remote control motor being wirelessly connected to a receiving module, constituting an overall remote control switch mechanism.

[0005] Furthermore, the fixing mechanism includes a U-shaped support bracket and a fastening screw. The top surface of the U-shaped support bracket is provided with a threaded hole, which is screwed into the fastening screw. The lower end of the fastening screw is provided with a floating frustum-shaped fastening plate. The lower inner surface of the U-shaped support bracket is in contact with the bottom of the defibrillator.

[0006] Furthermore, the clamping mechanism includes an upper clamping plate, a lower clamping plate, a stepped shaft-shaped fastening bolt, and a guide post. The upper clamping plate is fixedly connected to the movable support plate. The upper clamping plate is provided with a screw hole, which is screwed to the fastening bolt. The lower end of the fastening bolt is provided with an optical axis, which is slidably connected to a sliding sleeve fixed to the lower clamping plate. The lower clamping plate is fastened to the lower end of the fastening bolt by a nut. The space between the upper clamping plate and the lower clamping plate is formed for placing the finger robot.

[0007] Furthermore, the clamping mechanism is fixedly connected to a guide post, and a guide sleeve that is slidably connected to the guide post is fixedly connected to the lower clamping plate.

[0008] Furthermore, the finger robot includes a shell, a drive and transmission mechanism, mechanical fingers, and a control and communication circuit board. The drive and transmission mechanism uses a micro DC geared motor in conjunction with a lead screw slider to convert the rotational motion of the motor into the linear reciprocating motion of the pressing head. The mechanical fingers extend out of the shell and achieve forward pressing or backward retraction and reset actions through the drive and transmission mechanism. The control and communication circuit board includes a built-in PCB control board that integrates a microcontroller, a Bluetooth communication module, a wireless receiving module, a motor drive circuit, a power management circuit, and a power supply interface.

[0009] Furthermore, the receiving module is wirelessly connected to the remote control motor of the moving mechanism, and the receiving module is wirelessly connected to the first control switch.

[0010] Furthermore, the finger robot is connected to the second control switch via Bluetooth.

[0011] Beneficial effects: Compared with the prior art, the present invention has 1. Easy and stable installation: The entire device can be quickly and securely fixed to the side wall of the defibrillator through the fixing mechanism. It is simple to operate and convenient to install and use the defibrillator in different scenarios without the need to modify the internal switch of the defibrillator. 2. Flexible gripping of finger robot: The gripping mechanism can precisely control the movement of the lower gripper to achieve stable gripping of the finger robot, and can be flexibly adjusted according to the size of the finger robot to ensure the firmness and reliability of the gripping. 3. Precise position adjustment: The moving mechanism drives the lead screw transmission pair to rotate through the remote motor, which in turn moves the moving support plate, thereby realizing the precise movement of the clamping mechanism and the finger robot on the U-shaped plate. This allows the pressing end of the finger robot to be accurately aligned with the defibrillator's charging button and electric shock button, improving the accuracy of operation. 4. Convenient remote control: The receiving module wirelessly connects to the remote control motor and the first control switch, while the finger robot connects to the second control switch via Bluetooth. Users can control the movement and pressing of the finger robot through the first and second control switches respectively without being near the defibrillator, realizing remote charging and discharging of the defibrillator, greatly shortening the operation time, and especially gaining valuable treatment time in emergency situations.

"Above," "below," "underneath," "left," "right," etc., are only used to indicate relative positional relationships, and when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0016] See appendix for details Figure 1-4 This embodiment provides a defibrillator with a remote control switch device, including a defibrillator 1. The defibrillator 1 has a remote control switch mechanism at its switch 20 position. The remote control switch mechanism includes a fixed mechanism, a moving mechanism, a clamping mechanism, and a finger robot 19. The moving mechanism is connected to the fixed mechanism and includes a Π-shaped bracket 6, a remote control motor 10, a lead screw transmission pair 7, and a moving support plate 9. The remote control motor is fixedly connected to the upper surface of the Π-shaped bracket via a support frame 4. The output end of the remote control motor is connected to the lead screw via a connecting flange. The lead screw is screwed to a sliding sleeve, forming a lead screw transmission pair. The sliding sleeve is fixedly connected to the moving support plate. A guide post and guide sleeve 8 are provided between the moving support plate and the upper surface of the Π-shaped bracket, forming a lifting mechanism for the moving mechanism. The clamping mechanism is fixedly connected to the moving support plate, and the finger robot is fixedly connected to the clamping mechanism. The remote control motor is wirelessly connected to a receiving module 11, forming an overall remote control switch mechanism. In this embodiment, the moving mechanism uses a mechanical lifting mechanism; a miniature linear guide structure can also be used for a simpler mechanism. The remote control motor 10 uses a stepper motor (such as 17HS19-2004S1) with a step angle of 1.8°. It is used with a microstepping driver to achieve positioning at the 0.01mm level, which is suitable for the small travel of the defibrillator button.

[0017] In a preferred embodiment, the fixing mechanism includes a U-shaped support bracket 2 and a fastening screw 3. The top surface of the U-shaped support bracket has a threaded hole that is screwed onto the fastening screw. A floating frustum-shaped fastening plate 5 is located at the lower end of the fastening screw. The lower inner surface of the U-shaped support bracket contacts the bottom of the defibrillator. Silicone anti-slip pads (hardness 50A) are added to the inner side of the U-shaped support bracket 2 and the bottom of the fastening plate 5 to prevent damage to the defibrillator casing and to increase friction.

[0018] In a preferred embodiment, the clamping mechanism includes an upper clamping plate 17, a lower clamping plate 18, a stepped shaft-shaped fastening bolt 13, and a guide post 16. The upper clamping plate is fixed to the movable support plate by screws. The upper clamping plate is provided with screw holes, which are screwed to the fastening bolts. The lower end of the fastening bolt is provided with an optical axis 13-1, which is slidably connected to a sliding sleeve 13-2 fixed to the lower clamping plate. The lower clamping plate is fastened to the lower end of the fastening bolt by a nut 13-3. The height of the sliding sleeve is slightly larger than the thickness of the lower clamping plate to ensure that the nut is not jammed when tightened, which facilitates the rotation of the stepped shaft-shaped fastening bolt and drives the lower clamping plate to move up and down. The space 12 for placing the finger robot is formed between the upper and lower clamping plates.

[0019] In a preferred embodiment, the clamping mechanism is fixedly connected to a guide post 14, and a guide sleeve 15 that is slidably connected to the guide post is fixedly connected to the lower clamping plate.

[0020] In a preferred embodiment, the finger robot is a miniaturized intelligent pressing terminal, whose structure mainly includes the following parts: case The cubic shell is made of ABS engineering plastic and has an anti-slip silicone pad or fixing interface on the bottom for use with the clamping mechanism to achieve overall positioning and clamping. Drive and transmission mechanism The housing has a built-in miniature DC geared motor, which, together with a lead screw slider, converts the rotational motion of the motor into the linear reciprocating motion of the pressing head. Press to activate the end It consists of a mechanical "finger" (i.e., a pressing lever) extending out of the housing and a flexible silicone pressing head at the end. The pressing lever is driven by a transmission mechanism, which can extend forward to press and retract backward to reset; the silicone pressing head can increase the contact area with the button and at the same time provide cushioning to prevent damage to the defibrillator panel; Control and communication circuit boards The built-in PCB control board integrates a microcontroller, Bluetooth communication module, wireless receiver module, motor drive circuit, power management circuit and power supply interface; Connection relationship between wireless receiver module, Bluetooth and control switch To achieve coordination between remote and local control, the circuit connection is divided into two parts: positioning control of the moving mechanism and pressing control of the finger robot. 1. Circuit connection of the moving mechanism The receiving module is electrically connected to the first control switch and also electrically connected to the remote control motor of the moving mechanism; Working logic: The first control switch sends a control signal, which is received and decoded by the wireless receiving module, driving the remote control motor to run, thereby moving the lead screw transmission pair and the clamping mechanism as a whole, so that the finger robot is aligned with the target button of the defibrillator. 2. Circuit connection of the finger robot Bluetooth communication module: Integrated on the control board of the finger robot, it communicates bidirectionally with the built-in microcontroller (MCU) of the finger robot; Second control switch: Establishes a wireless connection with the finger robot via Bluetooth communication module. The user operates the second control switch (or sends commands via APP), and the signal is transmitted to the MCU via Bluetooth module; MCU and drive circuit: After receiving the control command from the Bluetooth module, the MCU outputs a control signal to the motor drive circuit, which drives the built-in micro motor to run, thereby driving the push rod to complete the action of extending or retracting. Connection between the finger robot and the gripping assembly physical connection The shell of the finger robot is clamped between the first and second clamping plates of the clamping assembly. Anti-slip rubber pads can be provided on the inner side of the clamping plates to increase friction and prevent slippage. The space between the upper and lower clamping plates of the clamping mechanism forms a space for placing the finger robot, enabling opening and closing to clamp or release it. Installation and positioning The axis of the finger robot's pressing lever is coaxial with the axis of the defibrillator button, ensuring that the force direction is perpendicular to the button surface during pressing, thus avoiding pressing failure or button damage due to misalignment. This embodiment uses a commercially available Bluetooth graffiti smart home finger robot third generation app remote control with timed voice control thumb remote control. Since the finger robot in this embodiment is a commercially available product, its detailed structure is not shown in the figures.

[0021] Operation process 1. Fix the U-shaped support bracket to the side wall of the defibrillator 1, adjust the fastening screws of the fixing mechanism and drive the floating frustum-shaped fastening plate to fix the remote control switch mechanism to the side wall of the defibrillator 1. 2. Place the finger robot in the space between the upper and lower clamping plates, and rotate the stepped shaft-shaped fastening bolt to move the lower clamping plate to clamp the finger robot; 3. The receiving module is connected via the first control switch. The receiving module controls the rotation of the remote control motor, which in turn drives the lead screw transmission pair to rotate, causing the moving support plate to move up and down, and also driving the clamping mechanism to move. 4. The fixed cavity 12 moves to the top of the U-shaped plate 6, and the pressing end of the finger robot 19 is aligned with the charging button of the defibrillator 1. The user can control the pressing end of the finger robot 19 to move and charge the defibrillator 1 through the second control switch. The output end of the remote control motor 10 rotates in the opposite direction, moving the fixed cavity 12 to the lower end of the U-shaped plate 6, and the pressing end of the finger robot 19 is aligned with the defibrillator 1's shock button. The user can control the pressing end of the finger robot 19 to move and discharge the defibrillator 1 through the second control switch. Charging can be controlled directly outside the operating room, eliminating the need to go to the operating room to charge. The remote control switch mechanism can reduce the time doctors spend going to charge and shorten the defibrillation time. Repeat this step to complete the process.

[0022] Module chip selection The main control chip is Nordic nRF52840, which supports Bluetooth 5.1 protocol, low power mode (standby current <1μA), and has a built-in ARM Cortex-M4F processor.

[0023] The DRV8871 H-bridge driver chip has a maximum output of 3.6A, driving stepper motors and servo motors for finger robots, and supports PWM speed regulation 22.

[0024] The wireless receiver ESP32-C3 (receiver module 11) supports dual-mode communication (WiFi + Bluetooth), receives the first control switch command, and forwards it to nRF5284016.

[0025] The ADuM3160 isolation chip adds electrical isolation to the motor control circuit to prevent high voltage from damaging the control circuit of the defibrillator (withstand voltage 5kV).

[0026] Key Functionality Implementation 1. Two-stage safety control: the first and second control switches constitute a remote controller. First control switch: Remotely start / stop the mobile component via ESP32-C3, operating range ≥50 meters (open environment).

[0027] Second control switch: Bluetooth direct connection to the finger robot, sending encrypted commands (AES-128 encryption) to ensure that the pressing operation is only triggered by authorized users.

[0028] The first and second control switches are not the original buttons on the defibrillator, but rather two independent operating terminals added by this invention to achieve remote wireless control. Their specific locations and principles are as follows: First control switch (positioning control) Principle and function: It connects wirelessly to the receiving module. When the user operates it to send a signal, the receiving module receives the signal and drives the remote control motor of the moving mechanism to run, thereby moving the entire gripping mechanism and the finger robot up and down, so that the finger robot can be aligned with the defibrillator's charging button or discharge (shock) button.

[0029] Physical location: It is a mobile app that is separate from the defibrillator. Since its function is to move the robot's position in space, it is not drawn on the defibrillator body in the picture. It is a remote control device in the user's hand.

[0030] Second control switch (press control) Principle and Function: It connects directly to the built-in communication module of the finger robot via Bluetooth. When the first control switch brings the finger robot to the target button, the user operates the second control switch, and the command is sent to the finger robot via Bluetooth, driving the miniature motor inside the robot to complete the "extend finger to press" action.

[0031] Physical location: A separate mobile app from the defibrillator. It directly controls the movements of the finger robot, not shown in the image.

[0032] 2. Status Feedback Mechanism Install miniature pressure sensors (such as FSR402) on the clamping mechanism and the moving support plate to detect the clamping force and position in real time, and trigger an audible and visual alarm (buzzer + LED) when abnormalities occur.

[0033] Safety and compatibility design 1. EMC protection The control circuit board is equipped with a shield (0.3mm thick galvanized steel) and grounded to meet the YY 0505 medical device electromagnetic compatibility standard.

[0034] 2. Battery System It is powered by an 18650 lithium battery (3.7V / 3000mAh), supports USB-C fast charging, has a battery life of 72 hours (standby mode), and features an automatic low battery lock mechanism.

[0035] 3. Adaptability Verification Test mainstream defibrillator models (such as Philips HS1 and ZOLL AED Plus) to confirm that the clamping range is compatible with devices with a thickness of 30~150mm.

[0036] Prototype testing focus 1. Mechanical life test: The lead screw and slider are run continuously for 10,000 cycles, and the wear is checked (target wear <0.05mm).

[0037] 2. Response time optimization: The time from issuing the command to completing the compression action is reduced to ≤1.5 seconds (refer to the golden 4 minutes for defibrillator emergency treatment).

[0038] 3. Extreme environment verification: Functional stability within a temperature range of -20℃ to 50℃, meeting IP54 protection level (dustproof / splashproof).

[0039] The above detailed description of a defibrillator with a remote control switch device, with reference to the embodiments, is illustrative rather than limiting. Several embodiments may be listed within the defined scope. Therefore, variations and modifications without departing from the overall concept of the present invention should be within the protection scope of the present invention.
