Description

Technical Field

[0001] This utility model relates to the field of simulation medical technology, specifically a support platform for puncture simulation. Background Technology

[0002] In the medical field, puncture refers to the process of penetrating the skin or other tissues with a needle or other appropriate tool to obtain a sample, inject medication, or perform other medical procedures. Puncture has a wide range of applications in clinical practice. In puncture teaching, puncture simulation platforms are important equipment used for medical training and teaching, helping medical personnel practice puncture skills such as intravenous puncture and bone marrow aspiration. These platforms are widely used in medical education, first aid training, and continuing education to help participants improve their nursing and operational skills.

[0003] In existing methods of teaching puncture simulation platforms, the setup used to mimic skin is simply placed on the platform, which remains stationary and level. Trainees can then perform puncture simulation training by following the corresponding steps. However, in real clinical practice, doctors encounter various immediate changes and patient reactions. When performing puncture treatment on a patient in a vibrating ambulance, or when the ambulance is traveling on a bumpy road, how can medical personnel smoothly perform puncture treatment? Most simulators cannot simulate these dynamic changes, limiting the training of trainees' adaptability and thus reducing the practicality of puncture simulation platforms.

[0004] Therefore, we propose a support platform for puncture simulation in order to solve the problems mentioned above. Utility Model Content

Among the plurality of first gears, the outer surfaces of each pair of adjacent first gears are meshed together.

[0009] Preferably, load frames are fixed on opposite outer surfaces of the mounting bracket, and a connecting block is fixedly installed on the outer surface of one of the load frames, with a forward and reverse motor provided on the outer surface of the connecting block.

[0010] Preferably, the output shaft of the forward and reverse motor is fixedly connected to a rotating shaft, and the two ends of the rotating shaft respectively extend through the opposite sides of the two load frames, and the outer surface of the rotating shaft is fixedly connected to the interior of the load frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. To further improve the practicality of the puncture simulation support platform, when it is necessary to simulate puncture on an ambulance, the experimental item to be punctured is first placed on top of the support platform. Then, the servo motor is started to drive multiple eccentric wheels to rotate, compressing the support platform to different degrees to simulate a bumpy road surface. This makes the simulation support platform more versatile, allowing trainees to practice puncture under these conditions to improve their responsiveness. This solves the problem that existing puncture simulation support platforms are mostly static and cannot be used to practice trainees' responsiveness.

[0018] 2. When trainees need to practice piercing from different angles at the same position, the forward and reverse motors are activated, which drives the mold held by the two positioning components to rotate. When the mold rotates to the required angle, the forward and reverse motors are turned off. By rotating the mold, trainees can practice piercing at the same position in the mold from different angles, thereby further improving the practicality of the piercing simulation platform.

[0019] 3. After the simulated puncture model is placed on top of the receiving platform, two stepper motors are started to drive the two second gears to rotate, which in turn drives the two sets of matching cams to rotate in opposite directions. The rotation of the two cams drives the two second limit posts to rotate, which in turn drives the two clamps to rotate relative to each other, thereby clamping and fixing the mold. Through the action of the positioning components, the mold is effectively prevented from slipping off the outer surface of the receiving platform. Attached Figure Description

One end of each of the multiple springs 206 is fixedly connected to the inner wall of the movable frame 203. The other end of each spring 206 is fixedly connected to the outer surface of one side of the receiving platform 207. One end of the connecting shaft 209 is fixedly connected to the outer surface of one of the first gears 210. Among the multiple first gears 210, the outer surfaces of each pair of adjacent first gears 210 are meshed together. Load frames 102 are fixedly mounted on opposite outer surfaces of the mounting bracket 101. A connecting block 103 is fixedly mounted on the outer surface of one of the load frames 102. A forward and reverse motor 104 is provided on the outer surface of the connecting block 103. The output shaft of the forward and reverse motor 104 is fixedly connected to a rotating shaft 105. The two ends of the rotating shaft 105 respectively extend through the opposite outer surfaces of the two load frames 102. The outer surface of the rotating shaft 105 is fixedly connected to the interior of the bearing frame 106. The receiving platform 207... Two positioning components 3 are provided at the top, each including a mounting block 301. One outer surface of each mounting block 301 is fixedly connected to the other outer surface of the receiving platform 207. A stepper motor 302 is bolted to the bottom of each mounting block 301.

Two first limiting posts 304 are movably embedded on the outer surface of each mounting block 301. The outer surfaces of the four first limiting posts 304 are rotatably connected to the interior of the four cams 305.

A second connecting rod 310 is movably fitted between the outer surfaces of each adjacent fourth limiting post 309 and third limiting post 308.

[0032] In this embodiment, to further improve the practicality of the puncture simulation support platform, when it is necessary to simulate puncture on an ambulance, the experimental item to be punctured is first placed on top of the support platform 207 and between two positioning components 3. Then, two stepper motors 302 are started, driving two second gears 303 to rotate, thereby driving two sets of matching cams 305 to rotate in opposite directions. The rotation of the two cams 305 drives two second limiting posts 306 to rotate, thereby driving two clamps 307 to rotate relative to each other, thus clamping and fixing the mold. Through the action of the positioning components 3, the mold is effectively prevented from slipping off the outer surface of the support platform 207. Then, the servo motor 208 is started, driving the connecting shaft 209 to rotate, thereby driving the first gear 210 connected to it to rotate, thereby driving the other first gears 210 to rotate, thereby driving multiple rotating rods 211 to rotate, thereby driving multiple eccentric wheels 212 to rotate, such as Figure 6 As shown, multiple eccentric wheels 212 are unevenly arranged on the surface of multiple rotating rods 211. The purpose is to make the rods undulate up and down during rotation, applying varying degrees of pressure to the support platform 207 to simulate a bumpy road surface. Furthermore, the lengths of the multiple eccentric wheels 212 are matched to the width of the support platform 207. Then, the drive motor 201 is activated, driving the lead screw 202 to rotate, which in turn drives the moving frame 203 to move horizontally along the direction of the lead screw 202. The limiting rod 204 limits the movement of the moving frame 203. The movement of the moving frame 203 causes the support platform 207 to move horizontally along the outer surface of the multiple eccentric wheels 212, causing the support platform 207 to undulate up and down. It then resets under the elastic action of multiple springs 206, and undulates again, repeating this cycle. This makes the puncture simulation support platform mimic a bumpy road surface, giving the simulation support platform variety. This allows trainees to practice puncture simulation under these conditions, improving their adaptability and solving the problem that existing puncture simulation support platforms are mostly static and cannot effectively train trainees' adaptability.

[0033] like Figures 1-3As shown, load racks 102 are fixed on opposite outer surfaces of the mounting frame 101. A connecting block 103 is fixedly installed on the outer surface of one of the load racks 102. A forward and reverse motor 104 is provided on the outer surface of the connecting block 103. A rotating shaft 105 is fixedly connected to the output shaft of the forward and reverse motor 104. The two ends of the rotating shaft 105 extend movably through to the opposite outer surfaces of the two load racks 102. The outer surface of the rotating shaft 105 is fixedly connected to the interior of the support frame 106.

[0034] In this embodiment, when trainees need to practice piercing from different angles at the same position, the forward and reverse motor 104 is first activated, driving the rotating shaft 105 to rotate, which in turn drives the support frame 106 to rotate, which in turn drives the moving frame 203 to rotate. The rotation of the moving frame 203 drives the receiving platform 207 to rotate, which in turn drives the two positioning components 3 to rotate, thereby driving the mold held by the two positioning components 3 to rotate. When the mold rotates to the required angle, the forward and reverse motor 104 is turned off. The forward and reverse motor 104 has a self-locking function, which is a mature existing technology and will not be described in detail here. By rotating the angle of the mold, trainees can practice piercing at the same position in the mold from different angles, thereby further improving the practicality of the piercing simulation support platform.

[0035] The usage and working principle of this device are as follows: To further improve the practicality of the puncture simulation support platform, when simulating puncture on an ambulance, the experimental item to be punctured is first placed on top of the support platform 207 and between the two positioning components 3. Then, the two stepper motors 302 are started, driving the two second gears 303 to rotate, which in turn drives the two sets of matching cams 305 to rotate in opposite directions. The rotation of the two cams 305 drives the two second limit posts 306 to rotate, which in turn drives the two clamps 307 to rotate relative to each other. The mold is clamped and fixed in place by the positioning component 3, which effectively prevents the mold from slipping off the outer surface of the receiving platform 207. Then, the servo motor 208 is started, driving the connecting shaft 209 to rotate, which in turn drives the first gear 210 connected to it to rotate, thereby driving the other first gears 210 to rotate, which in turn drives multiple rotating rods 211 to rotate, which in turn drives multiple eccentric wheels 212 to rotate, thus applying different degrees of pressure to the receiving platform 207 to simulate a bumpy road surface. Then, the drive motor 201 is started, driving the lead screw 202 to rotate, which in turn drives the moving frame. 203 moves horizontally along the direction of the lead screw 202. The movement of the moving frame 203 causes the receiving platform 207 to move horizontally along the outer surface of multiple eccentric wheels 212, causing the receiving platform 207 to rise and fall, and then reset under the elastic action of multiple springs 206, and then rise and fall again, thus repeating the cycle. This makes the puncture simulation bearing platform imitate a bumpy road surface, making the simulated bearing platform more diverse, allowing trainees to practice puncture under these conditions to improve their adaptability. When trainees need to practice puncture from different angles at the same position, the forward and reverse motors 104 are first started, carrying... The rotating shaft 105 rotates, which in turn drives the support frame 106 to rotate, which in turn drives the moving frame 203 to rotate. The rotation of the moving frame 203 drives the receiving platform 207 to rotate, which in turn drives the two positioning components 3 to rotate, thereby driving the mold held by the two positioning components 3 to rotate. When the mold rotates to the required angle, the forward and reverse motors 104 can be turned off. The forward and reverse motors 104 have a self-locking function, which is a mature technology and will not be described in detail here. By rotating the mold angle, trainees can practice piercing the same position in the mold from different angles.

[0036] The wiring diagrams of the forward and reverse motor 104, drive motor 201, servo motor 208 and stepper motor 302 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the forward and reverse motor 104, drive motor 201, servo motor 208 and stepper motor 302 will not be explained in detail.

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