An L-shaped vertical plate is fixedly arranged above the workbench, and a display screen is arranged on the front end surface of the L-shaped vertical plate, and there are two display screens. A detection seat is arranged on one side of the two display screens, and a detection pen is arranged between the detection seat and the display screen, and one end of the detection pen is electrically connected to the detection seat, and the detection pen is fixedly connected to the L-shaped vertical plate through a fixing ring, and a fixing table is arranged on the upper surface of the workbench, and a fixing cylinder is arranged above the fixing table, and the fixing cylinder is fixedly connected to the L-shaped vertical plate, and a turntable is arranged on the upper surface of the fixing table, and a fixing plate is fixedly arranged on the upper surface of the turntable, and there are two fixing plates, and a mounting portion is arranged below the fixing cylinder.

[0004] However, there are some problems in the use of the above device: first, the shapes of medical devices of different models and sizes vary greatly, and it is difficult to effectively fix all devices by relying solely on the splint.

The operator needs to manually remove the detection pen and detect each detection point one by one, which greatly increases the detection time. At the same time, during the detection process, the operator needs to constantly adjust the position of the detection pen, which increases the complexity of the operation. Summary of the invention

[0015] As a preferred medical device circuit fault detection device of the present invention, the center fixed sleeve on the surface of the bidirectional screw is provided with a No. 2 worm gear, the bottom of the No. 2 worm gear is meshingly connected with a No. 2 worm, one side of the inner wall of the rectangular groove is fixedly connected to a second motor, the output shaft of the second motor is fixedly connected to one end of the No. 2 worm, the two horizontal movable plates at the bottom close to each other are both rotatably connected to a fault detection pen, the two horizontal movable plates at the bottom away from each other are both rotatably connected to an inclined No. 2 electric push rod, and the telescopic ends of the bottoms of the two No. 2 electric push rods are rotatably connected to the sides of the two fault detection pens away from each other.

[0016] A detection method for a medical device circuit fault detection device: S1: Place the medical device to be tested at the top center of the work plate, ensure that it is directly above the positioning shell, connect the device to the power supply, ensure that all electronic components are working properly, start the negative pressure pump, and ensure that it is in standby state; S2: Start the first motor through the control system. The output shaft of the first motor drives the No. 1 worm to rotate. When the No. 1 worm rotates, the No. 1 worm gear meshing with it rotates accordingly. The No. 1 worm gear is fixed on the shaft, so the shaft also starts to rotate. The active bevel gear ring fixed on the top of the shaft rotates accordingly. The active bevel gear ring meshes with the four driven bevel gears, driving the four driven bevel gears to rotate. When the driven bevel gears rotate, the horizontal threaded rod fixed to it also rotates accordingly. Since the horizontal moving block is threadedly connected to the horizontal threaded rod, the rotation of the horizontal threaded rod will push the horizontal moving block to slide along the slide groove. The movement of the horizontal moving block will drive the L-shaped connecting rod to slide along the guide groove, so that the arc clamping plate moves toward the center and initially clamps the medical device. After the arc clamping plate initially clamps the medical device, the negative pressure pump is started. The negative pressure pump extracts the air in the air cavity through the air inlet pipe to form a negative pressure. The air cavity transmits the negative pressure to the rubber suction head in the mounting shell through the elastic air supply pipe. The rubber suction head is adsorbed on the surface of the medical device to further enhance the clamping effect. S3: Start multiple No. 1 electric push rods to move their telescopic ends downward, driving the positioning frame to descend to a position close to the medical device, start the second motor, and the output shaft of the second motor drives the No. 2 worm to rotate. When the No. 2 worm rotates, the No. 2 worm wheel meshing with it rotates accordingly. The No. 2 worm wheel is fixed on the bidirectional lead screw, so the bidirectional lead screw also starts to rotate. When the bidirectional lead screw rotates, the two horizontal threaded sleeves threadedly connected to it move in opposite directions. The movement of the horizontal threaded sleeves drives the horizontal moving plate to slide along the rectangular groove. The movement of the two horizontal moving plates drives the fault detection pen to move horizontally and adjust to the designated detection point position. Start two No. 2 electric push rods to move their telescopic ends downward, driving the fault detection pen to contact the detection point on the circuit board. The fault detection pen performs fault detection on the circuit. The detection data is transmitted to the control system through the sensor. The control system automatically records the detection data, generates a detailed detection report, and displays the detection results on the display screen for the convenience of staff to view in time; S4: After the test is completed, the negative pressure pump is turned off to release the negative pressure in the air cavity. The rubber suction head no longer absorbs the medical device. The control system reversely starts the first motor to move the arc-shaped clamping plate outward to release the medical device. The operator removes the tested medical device from the positioning shell and exports the test report to an external storage device or the cloud for subsequent analysis and archiving.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention places the medical device to be tested at the top center of the working plate to ensure that it is located directly above the positioning shell, and starts the first motor through the control system. The output shaft of the first motor drives the No. 1 worm to rotate. When the No. 1 worm rotates, the No. 1 worm wheel meshing therewith rotates accordingly. The No. 1 worm wheel is fixed on the rotating shaft, so the rotating shaft also starts to rotate, and the active bevel gear ring fixedly mounted on the top of the rotating shaft rotates accordingly. The active bevel gear ring meshes with four driven bevel gears, driving the four driven bevel gears to rotate. When the driven bevel gears rotate, the horizontal threaded rod fixed thereto also rotates accordingly. Since the horizontal moving block is threadedly connected to the horizontal threaded rod, the rotation of the horizontal threaded rod will push the horizontal moving block to slide along the slide groove, and the movement of the horizontal moving block will drive the L-shaped connecting rod to slide along the guide groove, so that the arc-shaped clamping plate moves toward the center to clamp the medical device. At the same time, the negative pressure pump is started to extract the air in the air cavity through the air inlet pipe to form negative pressure. The air cavity transmits the negative pressure to the rubber suction head in the mounting shell through the elastic air supply pipe. The rubber suction head is adsorbed on the surface of the medical device to further enhance the clamping effect. This design not only improves the accuracy and safety of clamping, but also further enhances the clamping effect through negative pressure suction, ensuring the stability and reliability of the medical device during the detection process.

[0018] 2. The present invention starts a plurality of No. 1 electric push rods to move their telescopic ends downward, driving the positioning frame to descend to a position close to the medical device, starts the second motor, and the output shaft of the second motor drives the No. 2 worm to rotate. When the No. 2 worm rotates, the No. 2 worm wheel meshing with it rotates accordingly. The No. 2 worm wheel is fixed on the bidirectional screw, so the bidirectional screw also starts to rotate. When the bidirectional screw rotates, the two horizontal threaded sleeves threadedly connected thereto move in opposite directions. The movement of the horizontal threaded sleeves drives the horizontal moving plate to slide along the rectangular groove. The movement of the two horizontal moving plates drives the fault detection pen to move horizontally and adjust to the designated detection point position. The two No. 2 electric push rods are started to move their telescopic ends downward, driving the fault detection pen to contact the detection point on the circuit board. The fault detection pen performs fault detection on the circuit. The detection data is transmitted to the control system through the sensor. The control system automatically records the detection data, generates a detailed detection report, and displays the detection results on the display screen, which is convenient for the staff to check in time. The device significantly improves the detection efficiency and accuracy through the automated design of the fault detection mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

The four arc-shaped clamping plates 204 are arranged in a circular array on the top of the positioning shell 201 and are slidably connected to its top.

[0026] Furthermore, the bottoms of the four L-shaped connecting rods 203 extend to the interior of the positioning shell 201 and are fixedly connected to a horizontal moving block 205.

The control system automatically records the detection data, generates a detailed detection report, and displays the detection results on the display screen 302, which is convenient for the staff to check in time. The equipment significantly improves the detection efficiency and accuracy through the automated design of the fault detection mechanism 300.

[0037] A detection method for a medical device circuit fault detection device: S1: Place the medical device to be tested at the top center of the working board 101, ensuring that it is directly above the positioning shell 201, connect the device to the power supply, ensure that all electronic components are working properly, start the negative pressure pump 219, and ensure that it is in a standby state; S2: Start the first motor 213 through the control system, and the output shaft of the first motor 213 drives the No. 1 worm 212 to rotate. When the No. 1 worm 212 rotates, the No. 1 worm wheel 211 meshing with it rotates accordingly. The No. 1 worm wheel 211 is fixed on the rotating shaft 210, so the rotating shaft 210 also starts to rotate, and the active bevel gear ring 209 fixedly sleeved on the top of the rotating shaft 210 rotates accordingly. The active bevel gear ring 209 meshes with the four driven bevel gears 208, driving the four driven bevel gears 208 to rotate. When the driven bevel gears 208 rotate, the horizontal threaded rod 207 fixed thereto also rotates accordingly. Since the horizontal moving block 205 is threadedly connected with the horizontal threaded rod 207, the rotation of the horizontal threaded rod 207 will push the horizontal moving block 205 to slide along the slide groove 206, and the movement of the horizontal moving block 205 will drive the L-shaped connecting rod 203 to slide along the guide groove 202, so that the arc-shaped clamping plate 204 moves toward the center to initially clamp the medical device. After the arc-shaped clamping plate 204 initially clamps the medical device, the negative pressure pump 219 is started, and the negative pressure pump 219 extracts the air in the air cavity 217 through the air inlet pipe 218 to form a negative pressure. The air cavity 217 transmits the negative pressure to the rubber suction head 215 in the mounting shell 214 through the elastic air delivery pipe 216. The rubber suction head 215 is adsorbed on the surface of the medical device to further enhance the clamping effect. S3: Start multiple No. 1 electric push rods 304 to move their telescopic ends downward, driving the positioning frame 303 to descend to a position close to the medical device, and start the second motor 312. The output shaft of the second motor 312 drives the No. 2 worm 311 to rotate. When the No. 2 worm 311 rotates, the No. 2 worm wheel 310 meshing therewith rotates accordingly. The No. 2 worm wheel 310 is fixed on the bidirectional screw rod 308, so the bidirectional screw rod 308 also starts to rotate. When the bidirectional screw rod 308 rotates, the two horizontal threaded sleeves 307 threadedly connected thereto move in opposite directions. The movement of the horizontal threaded sleeves 307 drives the horizontal moving plate 306 to slide along the rectangular groove 305. The movement of the two horizontal moving plates 306 drives the fault detection pen 313 to move horizontally and adjust to the designated detection point position, and the two No. 2 electric push rods 314 are started to move their telescopic ends downward, driving the fault detection pen 313 to contact the detection point on the circuit board. The fault detection pen 313 performs fault detection on the circuit board, and the detection data is transmitted to the control system through the sensor. The control system automatically records the detection data, generates a detailed detection report, and displays the detection results on the display screen 302, which is convenient for the staff to view in time; S4: After the test is completed, the negative pressure pump 219 is turned off to release the negative pressure in the air cavity 217. The rubber suction head 215 no longer absorbs the medical device. The control system reversely starts the first motor 213 to move the arc-shaped clamping plate 204 outward to release the medical device. The operator removes the tested medical device from the positioning shell 201 and exports the test report to an external storage device or the cloud for subsequent analysis and archiving.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
