DETAILED DESCRIPTION

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Embodiment: A hemodialysis access puncture simulation training device, such as Figure 1-Figure 3 As shown, it includes a plastic model 1 and a replacement device 2. The plastic model 1 is connected with the replacement device 2. The replacement device 2 includes a skin 201, a lock base 202, an insertion buckle 203, an extrusion column 204, an extrusion block 205 and an elastic member 206. The plastic model 1 is provided with a skin 201. The plastic model 1 is fixedly connected with a lock base 202. The lock base 202 has four. Through holes are provided on both sides of the lock base 202. The bottom of the skin 201 is fixedly connected with the insertion buckle 203. The insertion buckle 203 is inserted into the bottom of the skin 201. The bottom of the insertion buckle 203 is spherical, and the bottom of the insertion buckle 203 can slide inside the lock base 202. The two through holes of the lock base 202 are slidably connected with an extrusion column 204, and the extrusion column 204 is fixedly connected with an extrusion block 205. The extrusion block 205 is inside the lock base 202, and an elastic member 206 is sleeved on the extrusion column 204. One end of the elastic member 206 is fixedly connected to the extrusion block 205, and the other end of the elastic member 206 is fixedly connected to the lock base 202.

[0023] like Figure 1-Figure 3 As shown, the replacement device 2 is fixedly connected to the interior of the simulation device 3, and the simulation device 3 includes a storage tube 301 and an anti-leakage plug 302. The replacement device 2 is fixedly connected to the interior of two storage tubes 301 for storing simulated plasma liquid, and the two ends of the storage tubes 301 are respectively fixedly connected to the anti-leakage plugs 302.

[0024] like Figure 2 and Figure 4 As shown, the plastic model 1 is fixedly connected to a conveying mechanism 4, which includes a pipeline 401, a conveying port 402 and a T-shaped interface 403. Two pipelines 401 are fixedly connected to the plastic model 1. The top of the pipeline 401 is fixedly connected to the conveying port 402, and the conveying port 402 can be inserted into the storage tube 301 and communicates with the storage tube 301. The pipeline 401 is fixedly connected to a T-shaped interface 403.

[0025] like Figure 5As shown, a conveying device 5 is clamped on the conveying mechanism 4, and the conveying device 5 includes a conveying pump 501, a switch 502 and a conveying pipe 503. The conveying mechanism 4 is provided with a conveying pump 501, and a switch 502 is fixedly connected to the surface of the conveying pump 501. The conveying pump 501 is connected to a conveying pipe 503, and the conveying pipe 503 is a hose, and the conveying pipe 503 is fixedly connected to the T-shaped interface 403.

[0026] like Figure 1 As shown, it also includes vascular lines 6. The epidermis 201 is divided into two types, one of which is provided with vascular lines 6, and the other is not provided with any.

[0027] like Figure 1 As shown, grooves 7 are provided on both sides of the surface skin 201 .

[0028] When medical staff conduct simulation training, they need to use a needle to pierce the epidermis 201 multiple times, causing damage to the epidermis 201. When the number of piercings is too many, the epidermis 201 will be damaged to a certain extent and needs to be replaced. Therefore, when the damaged epidermis 201 needs to be replaced, the damaged epidermis 201 is pulled out, and the epidermis 201 is pulled through the groove 7 to move the epidermis 201 upward. The epidermis 201 drives the insertion buckle 203 to move upward, and the spherical bottom of the insertion buckle 203 is separated from the extrusion block 205. Then the elastic member 206 is reset, and the elastic member 206 drives the extrusion block 205 and the extrusion column 204 to move inward. At this time, the epidermis 201 is separated from the plastic model 1, and then the epidermis 201 continues to move upward until the insertion buckle 203 is completely separated from the locking base 202. ; Take out the new epidermis 201 and move the epidermis 201 downward. The epidermis 201 drives the insertion buckle 203 to move downward, so that the insertion buckle 203 is inserted into the interior of the lock base 202. The insertion buckle 203 continues to move downward, and the spherical bottom of the insertion buckle 203 contacts the extrusion block 205, so that the extrusion block 205 and the extrusion column 204 move to both sides. The movement of the extrusion block 205 compresses the elastic member 206. When the insertion buckle 203 is completely inserted into the lock base 202, the epidermis 201 contacts the plastic model 1. At this time, the extrusion block 205 fixes the bottom of the insertion buckle 203, so that the insertion buckle 203 no longer moves. At this time, the replacement and installation of the epidermis 201 is completed, and the replacement of the epidermis 201 is completed, which plays the role of replacing the damaged epidermis 201 and achieves the effect of reducing loss.

[0029] The end of the delivery tube 503 is connected to the simulated plasma bag. When the new epidermis 201 is replaced, the epidermis 201 contacts the plastic model 1, and the top of the delivery port 402 penetrates into the bottom of the epidermis 201, and then penetrates into the storage tube 301 inside the epidermis 201. At this time, the delivery device 5 is started, and the liquid in the simulated plasma bag will pass through the delivery tube 503 and the T-shaped interface 403 in turn, and then be delivered from the delivery port 402 to the two pipes 401 and enter the two storage tubes 301. The delivery device 5 can control the flow rate of the liquid. When the liquid inside the tube 301 is used up, the liquid can be replenished in time to the inside of the storage tube 301 to prevent the liquid in the storage tube 301 from running out and requiring frequent replacement of the epidermis 201; when the epidermis 201 needs to be replaced, the conveying device 5 controls the liquid to stop being transported into the storage tube 301. When the epidermis 201 is replaced, the conveying device 5 is started again to drive the liquid to flow, so that the liquid inside the storage tube 301 can be continuously replenished, thereby reducing the time consumption when replacing the epidermis 201 and reducing the waste of the epidermis 201.

[0030] When a beginner uses the device, the epidermis 201 with the vascular patterns 6 can be replaced, and medical staff can practice with the vascular patterns 6 on the epidermis 201, which serves as an auxiliary practice for beginners and enables them to get started with hemodialysis access puncture more quickly. Therefore, the device can be suitable for users with different learning progress, thereby improving the scope of application of the device.

[0031] The groove 7 can better enable medical personnel to disassemble the epidermis 201, making the device easy to disassemble and improving the convenience of using the device.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
