[0002] Lumbar punctures are used for both diagnostic and therapeutic purposes. To perform this procedure safely and effectively, physicians need to understand the contraindications, the relevant anatomy, and methods to minimize the risk of complications. Although lumbar punctures are rarely dangerous, when they occur, they can be serious and potentially life-threatening. Understanding the indications, contraindications, and proper procedures for lumbar punctures can minimize the risk of danger.

[0003] The prior art discloses a teaching lumbar puncture practice mold (publication number CN212084492U), which includes a trunk simulation block, wherein a placement cavity is provided inside the trunk simulation block for placing a spinal simulation block... An insertion hole is provided on the front side of the trunk simulation block, and the insertion hole corresponds to the puncture sleeve and is used for placing an epidermal simulation block; the spinal simulation tube adopts a multi-section detachable structure, and the puncture sleeve can be replaced separately, thereby ensuring the practice effect while reducing waste, being simple and convenient to operate, and having a good use effect.

[0004] When the above-mentioned teaching lumbar puncture practice mold is used for actual lumbar puncture practice, the puncture needle is directly inserted into the lumbar simulation tube, and it lacks simulation of the lumbar spine and the yellow ligament, resulting in poor simulation effect, which will affect the students' practice effect. Therefore, we need to propose a teaching lumbar puncture practice mold. Utility Model Content

[0024] See also Figure 1-6 The utility model provides a technical solution: a teaching lumbar puncture practice mold, comprising a trunk simulation block 1, a first mounting frame 4 and a second mounting frame 5 are damped and plugged in the trunk simulation block 1, a spine simulation tube 6 and multiple groups of spine simulation blocks 7 are arranged in the first mounting frame 4 and the second mounting frame 5, the multiple groups of spine simulation blocks 7 are all fitted with the spine simulation tube 6, yellow ligament simulation blocks 20 are arranged between adjacent spine simulation blocks 7, the multiple groups of spine simulation blocks 7 are connected through the yellow ligament simulation blocks 20, the spine simulation tube 6 is connected with a first liquid inlet pipe 8, the first liquid inlet pipe 8 is sealed and installed with a first sealing plug 9, and the side of the first mounting frame 4 is provided with an avoidance hole 11;

[0025] The plurality of groups of spine simulation blocks 7 are all connected with a second liquid inlet pipe 13, and a second sealing plug 14 is sealed and installed on the second liquid inlet pipe 13;

[0026] The first mounting frame 4 and the second mounting frame 5 are both provided with an avoidance groove 12, and the first liquid inlet pipe 8, the first sealing plug 9, the second liquid inlet pipe 13 and the second sealing plug 14 are all arranged in the avoidance groove 12;

[0027] Through the setting of the first sealing plug 9, the simulation liquid can be added into the spine simulation tube 6 and the spine simulation block 7 by opening the first sealing plug 9 and the second sealing plug 14. The simulation liquid in the spine simulation tube 6 and the spine simulation block 7 has different colors, which is convenient for students to distinguish;

[0028] The trunk simulation block 1 includes a first block 101 and a second block 102. The first block 101 and the second block 102 are both provided with a plug-in slot 3. The first mounting frame 4 and the second mounting frame 5 are respectively plugged into the plug-in slots 3 provided in the first block 101 and the second block 102.

[0029] The first block 101 and the second block 102 are both provided with drainage grooves 15 for draining the simulated liquid in the spine simulation tube 6 and the spine simulation block 7. The first mounting frame 4 and the second mounting frame 5 are both provided with mounting grooves 16. The mounting grooves 16 are plugged with collection boxes 17. The sides of the first mounting frame 4 and the second mounting frame 5 are both fixedly connected with handles 10.

[0030] By setting the drainage groove 15, when the simulation fluid leaks after the spine simulation tube 6 and the spine simulation block 7 are used for a long time, the leaked simulation fluid can be discharged into the collection box 17 through the drainage groove 15 for collection;

[0031] A sealing gasket 21 is provided between the first block 101 and the second block 102, and a skin simulation block 2 is provided on the side of the first block 101;

[0032] By disposing the sealing gasket 21, the sealing effect between the first block 101 and the second block 102 can be improved.

[0033] A connecting block 18 is hingedly connected to the top of the first block 101, and a fixing block 19 is fixedly connected to the top of the second block 102. The connecting block 18 is fixedly mounted on the fixing block 19 by fixing screws.

[0034] Through the setting of the connecting block 18, by loosening the fixing screws, the fixing screws can be removed, and the first block 101 and the second block 102 can be opened to clean the first block 101 and the second block 102;

[0035] In the specific use process, when practicing lumbar puncture, the student operates the puncture needle to first pierce the epidermal simulation block 2. After the puncture needle pierces the epidermal simulation block 2, it will pass through the avoidance hole 11. If the puncture needle pierces the spinal simulation block 7, the spinal simulation block 7 can block the puncture needle, so that the student can know that the puncture point is wrong and can practice lumbar puncture again, thereby improving the simulation effect. If the student continues to push the puncture needle and causes the puncture needle to enter the spinal simulation block 7, the simulation liquid in the spinal simulation block 7 will flow out. The color of the simulation liquid in the spinal simulation block 7 is different from that of the simulation liquid in the spinal simulation tube 6, so that the student can be aware of the serious mistake;

[0036] For example, when the puncture needle is inserted into the lumbar intervertebral space, it will first pass through the yellow ligament, and there will be a feeling of falling into the air after passing through the yellow ligament. The feeling of falling into the air after the puncture needle passes through the yellow ligament can enable students to know that the puncture point is correct. By continuing to push the puncture needle, the puncture needle can penetrate into the lumbar simulation tube, so that the simulation fluid in the lumbar simulation tube can flow out through the puncture needle.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
