Description

Technical Field

[0001] The present application relates to the field of clinical puncture teaching technology, and in particular to a chest and back puncture training simulation device. Background Art

[0002] Puncture technology is a key focus of medical education, and it is necessary to fully utilize high-tech means to establish a "medical simulation training room" to provide a true training base for medical students. For example, the dorsal thoracentesis monitoring and assessment guidance model in publication number CN201120260808.5 has the following shortcomings:

[0003] The above patent simulates pleural effusion by installing multiple water bags on both sides of the model's ribs, and then conducts puncture training. However, since the water bags will leak due to puncture if they are filled with water after puncture, they are often replaced after use. The above device cannot quickly replace the simulated organs inside the model, which will greatly waste teaching time. Utility Model Content

[0008] By adopting the above technical solution, storage bin A and storage bin B can store the first connecting rod and the second connecting rod, so that the front chest model and the back model fit more closely, and the second connecting rod can drive the pull rod to move, and the L-shaped slide rail can play a guiding and supporting role, and the U-shaped telescopic rod can extend outward the distance of the L-shaped slide rail.

[0009] Preferably, the moving mechanism further comprises a moving slot provided in the middle of the second connecting rod, and a first rotating shaft connected to one end of the pull rod is slidably provided in the inner cavity of the moving slot.

[0010] By adopting the above technical solution, the movable slide groove can drive the movement of the first rotating shaft, and due to its sufficient length, it can allow the long axis movement of the first rotating shaft, so that the first rotating shaft can better drive the movement of the tension rod.

[0011] Preferably, two second rotating shafts fixed on the upper part of the viscera model fixing frame are slidably provided in the inner cavity of the L-shaped slide rail, and one of the two second rotating shafts is connected to the end of the pulling rod away from the first rotating shaft at one end away from the viscera model fixing frame.

[0012] By adopting the above technical solution, the second rotating shaft can drive the viscera model fixing frame to move back and forth along the track of the L-shaped slide rail.

[0013] Preferably, a limiting plate for limiting is fixedly provided on the side of the second rotating shaft connected to the pulling rod away from the U-shaped telescopic rod.

[0014] By adopting the above technical solution, the limiting plate can prevent a dead angle where movement is impossible to form between the pull rod and the second pull rod.

[0015] Preferably, the L-shaped slide rail is located at one end of the U-shaped telescopic rod and is fixed with a fixing plate fixed to the side wall of the back model.

[0019] Preferably, the side surface and upper surface of one end of the U-shaped telescopic rod connecting to the L-shaped slide rail are fixed with two T-shaped slide rods with the same structure and installation method, and one side of the two T-shaped slide rods are slidably provided with two T-shaped slide grooves with the same structure opened on the L-shaped slide rail.

[0020] By adopting the above technical solution, the T-shaped sliding rod and the T-shaped sliding groove both have smooth surfaces, which can make the U-shaped telescopic rod run more smoothly in the L-shaped sliding rail.

[0021] Preferably, the U-shaped telescopic rod is provided with a spring fixed to the L-shaped slide rail in the middle of the surface of one side of the tension rod.

[0022] By adopting the above technical solution, the spring can help the U-shaped telescopic rod to reset.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By pulling the front chest model, the first connecting rod and the second connecting rod are unfolded and moved in the storage bin B. When the second connecting rod moves in the inner cavity of the storage bin B, the central moving slide moves with the first rotating shaft, thereby driving the pull rod to move to one side, and the pull rod drives the second rotating shaft to move together. When the second rotating shaft moves, it will move with the visceral model fixing frame and move in the inner cavity of the L-shaped slide rail. During the movement, the other second rotating shaft pushes out the U-shaped telescopic rod, extending the track of the L-shaped slide rail outward. When the visceral model fixing frame is pulled out, the parts that need to be replaced can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Reference Figure 6-Figure 8 A T-shaped slide bar 8 is fixed on the side of one end of the U-shaped telescopic rod 58 connected to the L-shaped slide rail 54, and a T-shaped slide bar 8 is also fixed on the upper surface of the U-shaped telescopic rod 58, and the two T-shaped slide bars 8 have the same structure and installation method, and a T-shaped slide groove 9 is opened on the side of the end of the L-shaped slide rail 54 connected to the U-shaped telescopic rod 58, and a T-shaped slide groove 9 is also opened on the upper part of the L-shaped slide rail 54, and the structures of the two L-shaped slide rails 54 are the same, and the two T-shaped slide bars 8 and the two T-shaped slide grooves 9 are arranged to slide with each other, and the U-shaped telescopic rod 58 is located on one side surface of the tension rod 53 and is fixedly connected to one end of the spring 11, and the spring 11 extends into one side of the L-shaped slide rail 54 away from the end of the U-shaped telescopic rod 58 and is fixedly connected to the L-shaped slide rail 54.

[0044] One end of the second connecting rod 51 is connected to the inner cavity of the storage bin A301, and the other end is slidably set in the storage bin B302. When the storage bin B302 moves, the second connecting rod 51 will also move from one side of the inner cavity of the storage bin B302 to the other side of the inner cavity of the storage bin B302. When the second connecting rod 51 moves, one end of the movable slide groove 52 opened in the middle thereof abuts against the first rotating shaft 55, and moves the first rotating shaft 55 together, thereby driving the pull rod 53 to move to one side, and the other end of the pull rod 53 is rotatably connected to the second rotating shaft 59, and the second rotating shaft 59 is slidably set in the L-shaped slide rail 54, and the lower part of the second rotating shaft 59 is fixedly connected to the viscera model fixing frame 10, so when the pull rod 53 drives the second rotating shaft 59 to move, the second rotating shaft 59 will carry the viscera model fixing frame 10 to move in the inner cavity of the L-shaped slide rail 54 according to the track of the L-shaped slide rail 54.

[0045] During the movement, the second rotating shaft 59 located in the middle of the L-shaped slide rail 54 will abut against the semicircular inner wall of the U-shaped telescopic rod 58, and then the U-shaped telescopic rod 58 will be pushed out, so that the track of the L-shaped slide rail 54 can be extended outward, and the length of the movable slide groove 52 in the middle of the second connecting rod 51 can meet the tension rod 53 to pull out the spring 11 and move it to one side for easy replacement. Since the T-shaped slide bars 8 are provided on the side and upper part of the U-shaped telescopic rod 58, and they slide with the T-shaped slide grooves 9 opened on the side and upper part of the L-shaped slide rail 54, The L-shaped guide rail 54 is provided at the bottom of the second rotating shaft 59, so that the top surface of the T-shaped slide bar 8 and the top surface of the T-shaped slide groove 9 are in the same plane, so that the movement process of the second rotating shaft 59 is always kept on a horizontal plane. When the second rotating shaft 59 is pulled back, the spring 11 provided at the connection between the L-shaped slide rail 54 and the U-shaped telescopic rod 58 can pull the U-shaped telescopic rod 58 back to its original position, and the limit plate 56 fixed on one side of the upper part of the second rotating shaft 59 can prevent the pulling rod 53 from being at right angles to the L-shaped slide rail 54 under the action of the reverse force, so that the pulling rod 53 may not be able to pull the second rotating shaft 59.

[0046] It should be noted that, of the second rotating shaft 59 connected to the pull rod 53, only the connecting part can rotate, and the rest are fixed. When the front chest model 1 is separated from the back model 2, the pull rod 53 first pulls the second rotating shaft 59 out of the vertical slide rail near the inner wall of the back model 2, and converts it to the horizontal slide rail through the arc slide rail, and then performs horizontal movement. The simulated organs inside the front chest model 1, the back model 2, and the internal organs model fixing frame 10 in the above device are all existing technologies, and their structural principles will not be described in detail. Moreover, the device is located at Figure 1 The upper body of the dummy is covered with a circle of artificial skin, which is attached to the chest model 1 and the back model 2 by Velcro to cover the entire chest cavity and waist and abdomen to simulate the state of a real person. Figure 1The dummy model is fixed, the front chest model 1 is movable, and sensors are provided between each rib of the front chest model 1 and at the lower spine of the back model 2 to detect whether the puncture position is correct. The sensors need to be connected to the alarms on the dummy's legs to prompt the puncturing personnel whether the operation is correct. However, since the above are all existing structures, their structural principles will not be described in detail here.

[0047] The implementation principle of a chest and back puncture training simulation device in an embodiment of the present application is: when it is necessary to replace the simulated alveoli and other fluid-filled organs inside the dummy for the next training, the front chest model 1 can be pulled outward first. At this time, the front chest model 1 will be separated from the back model 2, and at the same time, the first connecting rod 4 and the second connecting rod 51 are pulled to move in the storage bin B302.

[0048] When the second connecting rod 51 moves from one side of the inner cavity of the storage bin B302 to the other side of the inner cavity of the storage bin B302, one end of the movable slide 52 opened in the middle thereof abuts against the first rotating shaft 55, and moves the first rotating shaft 55 together, thereby driving the pull rod 53 to move to one side, and the other end of the pull rod 53 drives the second rotating shaft 59 to move together. When the second rotating shaft 59 moves, it will carry the viscera model fixing frame 10 to move along the track of the L-shaped slide rail 54 in the inner cavity of the L-shaped slide rail 54. During the movement, the second rotating shaft located in the middle of the L-shaped slide rail 54 The shaft 59 will abut against the semicircular inner wall of the U-shaped telescopic rod 58, and then the U-shaped telescopic rod 58 will be pushed out, so that the track of the L-shaped slide rail 54 can be extended outward. Since T-shaped slide bars 8 are provided on the side and top of the U-shaped telescopic rod 58, and they are slidably arranged with the T-shaped slide grooves 9 opened on the side and top of the L-shaped slide rail 54, the top surface of the T-shaped slide bar 8 and the top surface of the T-shaped slide groove 9 are in the same plane, so that the movement process of the second rotating shaft 59 is always maintained on a horizontal plane. When the viscera model fixing frame 10 is pulled out, the parts that need to be replaced can be replaced.

[0049] After replacement, push the chest model 1 in the opposite direction to make the chest model 1 closer to the back model 2. At this time, the second connecting rod 51 will pull the pull rod 53 and the second rotating shaft 59 to move in the opposite direction. At this time, the spring 11 arranged at the connection between the L-shaped slide rail 54 and the U-shaped telescopic rod 58 can pull the U-shaped telescopic rod 58 back to its original position, and the limit plate 56 fixed on one side of the upper part of the second rotating shaft 59 can prevent the pull rod 53 from forming a right angle with the L-shaped slide rail 54 under the force in the opposite direction, so that the pull rod 53 may not be able to push the second rotating shaft 59 back to its original position.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
