[0002] In clinical medicine, in order to drain abdominal fluid or take samples for biopsy of abdominal masses, experienced doctors are needed to puncture the abdomen with puncture equipment to drain the abdominal fluid or take samples of the mass.

Therefore, they usually use abdominal puncture models and conduct repeated training and practice to master the puncture technology before they can diagnose and treat patients.

The gravity ball 285 can randomly fall into a groove 282 through the cylinder 284 and press against a first switch 283 in the groove 282, so that the first electromagnetic block 299 of the first control component 29 is energized, and a resistor 287 connected to the first switch 283 is connected. The circuit is connected to the first electromagnetic block 299, so that the repulsive force generated by the first electromagnetic block 299 on the first magnetic block 298 after being energized can be randomly adjusted. When the resistance value of the resistor 287 is large, the repulsive effect generated by the first electromagnetic block 299 on the first magnetic block 298 is small, so that the downward movement distance of the mounting plate 291 is small. The downward movement of the mounting plate 291 can make the support 294 press against the second switch 292, and the third spring 219 is extended to make the water pump 211 work, and control the electromagnetic valves on the connecting pipe 212 and the water pipe 213 on one side thereof to open, so that the water in the water storage cylinder 26 is pumped to On the upper side of the bottom plate 23, as the water level in the water storage tube 26 drops, the float 214 moves downward, and at the same time, the first electromagnetic block 299 repels the first magnetic block 298, causing the mounting plate 291 to move downward accordingly, so that the second switch 292 continues to be in a state of being pressed by the support 294, so that the water pump 211 continues to pump water to the upper side of the bottom plate 23. Under the repulsive effect of the first electromagnetic block 299 on the first magnetic block 298, the mounting plate 291 will no longer move downward after moving to the maximum distance. As the float 214 moves downward, the support 294 does not Then the second switch 292 is pressed, the water pump 211 stops working, and the electromagnetic valve on the connecting pipe 212 on one side thereof is controlled to be closed, and the second telescopic tube 295 continues to maintain the pressing state on the third switch 293, so that when the resistance value of the resistor 287 is large, less water can be pumped to the upper side of the bottom plate 23, and vice versa, when the resistance value of the resistor 287 is small, more water can be pumped to the upper side of the bottom plate 23, so that the amount of water between the upper side of the bottom plate 23 and the corrugated plate 24 can be randomly adjusted to simulate different degrees of intra-abdominal fluid accumulation; Similarly, when simulating different positions of the upper abdomen, middle abdomen or lower abdomen where the abdominal effusion is located, the first touch panel 28 far from the side of the frame 21 and the second control component 217 in the frame 21 participate in the work, and the gravity ball 285 is put in through the opening on the upper side of the cylinder 284 close to the side of the frame 21. The gravity ball 285 can randomly fall into a groove 282 and press against a first switch 283 in a groove 282, so that the first electromagnetic block 299 of the second control component 217 is energized, and a resistor 287 connected to the first switch 283 is connected to the circuit, and the first electromagnetic block 299 of the second control component 217 repels the first magnetic block 298, so that the second control component 217 The mounting plate 291 of the second control member 217 moves upward, the fourth spring 222 stretches, the support 294 presses the second switch 292, the electric push rod 221 works, and drives the bottom plate 23 to move upward. After the mounting plate 291 of the second control member 217 moves upward to the maximum distance, as the bottom plate 23 moves upward, the support 294 no longer presses the second switch 292, and the electric push rod 221 stops working. When the resistance value of the randomly connected resistor 287 is large, the mounting plate 291 moves upward for a small distance, and the bottom plate 23 moves upward for a small distance. On the contrary, when the resistance value of the connected resistor 287 is small, the bottom plate 23 can move upward for a large distance, so that the different upper, middle and lower positions of the abdomen where the effusion is located can be simulated. Afterwards, the trainee can wear rubber gloves, cooperate with the ultrasonic probe 12 and the display device 13, and perform puncture training on the puncture block 22 through the puncture needle 11. When the puncture needle 11 reaches the position where the water body is located in the corrugated plate 24, the conductive block 215, the puncture needle 11 and the first indicator light 225 form a closed loop, and the first indicator light 225 lights up, which can remind the trainee that the puncture has reached the specified position. In addition, through the setting of the two first touch components 28, different degrees of water on the upper side of the bottom plate 23 and different positions of the bottom plate 23 can also be randomly combined to simulate puncture training under different conditions of intra-abdominal effusion, thereby improving the puncture training accuracy of the trainee; After the puncture training is completed, the connecting plate 272 of the first connecting member 27 can be moved upward to move the cylinders 284 on both sides upward, and the gravity balls 285 can be taken out. Then, under the elastic force of the first spring 273, the cylinders 284 can be moved downward to reset. After the two gravity balls 285 are taken out, they will no longer press the first switch 283, so that the first electromagnetic block 299 of the first control member 29 and the second control member 217 are powered off. Under the elastic force of the third spring 219, the mounting plate 291 of the first control member 29 can be moved upward to reset, so that the second telescopic tube 295 no longer presses the third switch 293, so that the drainage pump 210 can work and control the connecting pipe 212 on one side and the water pipe 217 to be connected. 3 is opened, and the water on the upper side of the bottom plate 23 is discharged into the water storage tube 26. After the discharge is completed, the float body 214 moves up to the uppermost side, and the second telescopic tube 295 presses the third switch 293 again, so that the drainage pump 210 stops working; similarly, under the elastic force of the fourth spring 222, the mounting plate 291 of the second control member 217 moves down and resets, and the pressing effect of the second telescopic tube 295 on the third switch 293 is released, so that the telescopic end of the electric push rod 221 drives the bottom plate 23 to move down and reset.
