Description

Technical Field

[0001] This utility model relates to the field of injection simulation hand technology, specifically a simulated injection hand. Background Technology

[0002] The simulated injection hand is a commonly used instrument for medical students. It is a simple device that simulates a human hand and is mainly used for medical education and training to provide opportunities for practical operation so that trainees can better cope with the challenges of actual clinical work. The skin part of the simulated injection hand is usually made of silicone, plastic elastomer mixture or other polymer materials to simulate the touch and elasticity of real skin.

[0003] Currently, patent CN218413793U discloses an injection simulation teaching device. The technical solution includes a support mechanism, an injection simulation mechanism, and a liquid circulation mechanism. The support mechanism further includes a moving platform and a clamping mechanism. The moving platform is equipped with the clamping mechanism and the liquid circulation mechanism. The clamping mechanism is equipped with the injection simulation mechanism. The injection simulation mechanism also includes a simulated arm, a simulated tube, and a reservoir bag. The simulated arm simulates the human forearm and hand to enhance the simulation's realism. The simulated arm has an outer skin sleeve made of transparent material, used for training with colored injection liquid to facilitate observation of whether the injection is injected into the correct location. Inside the simulated arm are the simulated tube and the reservoir bag to simulate human blood vessels and subcutaneous areas. The liquid circulation mechanism is connected to the simulated tube and the reservoir bag via pipes to circulate the colored liquid in the simulated tube and the reservoir bag, facilitating repeated injection simulation training. The liquid circulation mechanism is equipped with a switch. By using simulated tubes and reservoir bags to mimic human blood vessels and intradermal tissues, the simulation's realism is enhanced. The injection effect can be directly observed through the outer skin cover, increasing the intuitiveness and effectiveness of injection teaching. The injection effect can be reset by controlling the water pump with a switch, improving teaching and training efficiency.

[0004] However, the above-mentioned injection simulation teaching device still has the following problems in use: When performing injection simulation, due to the large number of blood vessels and the lack of anti-backflow structure in the device, the simulated medicine can easily enter multiple blood vessels during the actual injection process, resulting in a large error in the simulation results. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a simulated injection hand that adds an anti-backflow structure to the simulated blood vessel, thereby preventing the simulated medication from entering other blood vessels during simulated infusion.

[0006] The utility model provides the following technical solution: A simulation injection simulation hand, including a simulation hand body, inside which a simulated venous blood vessel is fixedly arranged. The lower end of the simulated venous blood vessel penetrates through a liquid collection bag, and a fixed plate is fixedly installed inside the simulated venous blood vessel. A diversion hole is opened at the middle position of the fixed plate. A guide rod is slidably arranged on the fixed plate, and a connecting spring is fixedly installed on the guide rod, and the connecting spring is fixedly installed on the fixed plate. A sealing plate is fitted inside the diversion hole opened at the middle position of the fixed plate, and the guide rod is fixedly installed on the sealing plate.

[0007] Further, the liquid collection bag is made of transparent polypropylene material, and a syringe connecting pipe penetrates through the lower end of the liquid collection bag. A scale bar is fixedly arranged on the liquid collection bag. With the above structure, it is convenient to view the injected liquid through the liquid collection bag.

[0008] Further, the sealing plate consists of two circular plate structures, and the circular plate with a small diameter is made of rubber material. The guide rods are arranged on the sealing plate at equal angles, and there are four guide rods in total. With the above structure, it is convenient to limit the movement range of the sealing plate under the action of the guide rods.

[0009] Further, a first magic tape is fixedly installed on the upper surface of the simulation hand body, and a second magic tape is fitted on the upper end of the first magic tape. Both the first magic tape and the second magic tape are of a "mouth" - shaped structure. With the above structure, it is convenient to replace the thickening pad through the first magic tape and the second magic tape.

[0010] Further, a dense hook is arranged on the upper surface of the first magic tape, and dense fluff is arranged on the lower surface of the second magic tape. With the above structure, it is convenient for the first magic tape and the second magic tape to be well adhered and fixed when they come into contact.

[0011] Further, a thickening pad is fixedly arranged on the upper end of the second magic tape, and both the thickening pad and the simulation hand body are made of silica gel material. With the above structure, it is convenient to simulate fat layers of different thicknesses by replacing the thickening pad.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This simulated injection hand effectively prevents the simulated drug solution from flowing back into other blood vessels by setting a fixation plate and a sealing plate inside the simulated vein, thus avoiding a reduction in the collected simulated drug solution and ensuring the accuracy of the simulation results. The volume of injected simulated drug solution can be monitored through a liquid collection bag and a graduated strip, and the injected drug solution can be collected for recycling. By replacing the thickened pad, it can be replaced after a long period of use. At the same time, replacing the thickened pad can effectively simulate different fat layer thicknesses, ensuring the realism of the simulation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-5This utility model provides a technical solution: a simulated injection hand, including a simulated hand body 1, inside which a simulated vein 2 is fixedly installed. A liquid collection bag 3 is inserted through the lower end of the simulated vein 2, and a fixing plate 6 is fixedly installed inside the simulated vein 2. A flow guide hole is opened in the middle of the fixing plate 6. A guide rod 7 is slidably installed on the fixing plate 6, and a connecting spring 8 is fixedly installed on the guide rod 7. The connecting spring 8 is fixedly installed on the fixing plate 6. A sealing plate 9 is fitted into the flow guide hole opened in the middle of the fixing plate 6. The guide rod 7 is fixedly installed on the sealing plate 9. The liquid collection bag 3 is made of transparent polypropylene, and a syringe connecting tube 4 is inserted through the lower end of the liquid collection bag 3. A scale strip 5 is fixedly installed on the liquid collection bag 3. The sealing plate 9 consists of two circular plate-shaped structures, and the smaller diameter circular plate is made of rubber. The guide rods 7 are set at equal angles on the sealing plate 9, and a total of four guide rods 7 are provided.

[0022] When a simulated injection needs to be performed on the simulated hand body 1, a syringe filled with simulated medication (the simulated medication is dyed water) is connected to an infusion needle. The infusion needle is then inserted into the simulated hand body 1, and the syringe can be pushed to inject the medication. As the puncture site becomes accurate, the simulated medication enters the simulated vein 2. At this point, the sealing plate 9 within the corresponding simulated vein 2 begins to push the simulated medication away from the fixed plate 6. The guide rod 7 restricts the movement of the sealing plate 9, as a connecting spring 8 is fixedly mounted on the guide rod 7 and connected to the fixed plate 6. The connecting spring 8 is then compressed and deformed, allowing the simulated medication to pass through smoothly. Once the simulated medication has completely passed through, the connecting spring 8 returns to its original shape. Then, the guide rod 7 is pulled, and the sealing plate 9 begins to move closer to the fixed plate 6 until the sealing plate 9 and the fixed plate 6 are tightly fitted. At this time, the backflow of the medicine can be effectively prevented. The injected simulated medicine enters the liquid collection bag 3. Because the liquid collection bag 3 is equipped with a scale bar 5, the amount of collected simulated medicine can be viewed through the scale bar 5. The amount of collected simulated medicine can be used to determine whether the puncture position has deviated (when the puncture position is deviated, some medicine will enter the simulated hand body 1, so the amount of collected simulated medicine will be less). Because the liquid collection bag 3 is equipped with a syringe connecting tube 4 at the lower end, the syringe connecting tube 4 can be connected to another syringe. At this time, by withdrawing the syringe, the simulated medicine in the liquid collection bag 3 can be extracted. Then, the positions of the two syringes can be switched to facilitate the next simulated injection.

[0023] A first magic tape 10 is fixedly installed on the upper surface of the simulation hand body 1, and a second magic tape 11 is贴合设置 with the upper end of the first magic tape 10. Both the first magic tape 10 and the second magic tape 11 are provided with a "mouth" - shaped structure. Dense hooks are provided on the upper surface of the first magic tape 10, and dense fluff is provided on the lower surface of the second magic tape 11. A thickening pad 12 is fixedly installed at the upper end of the second magic tape 11, and both the thickening pad 12 and the simulation hand body 1 are made of silicone material.

[0024] Because the first magic tape 10 is provided on the outer surface of the simulation hand body 1, the first magic tape 10 and the second magic tape 11 are adhesively bonded to each other, and the second magic tape 11 and the thickening pad 12 are connected to each other. Therefore, as the number of injections increases, the thickening pad 12 is likely to be damaged. At this time, it is difficult to view the position of the blood vessel. At this time, the thickening pad 12 can be removed and replaced to ensure the simulation effect. And by replacing the thickness of the thickening pad 12, the back of the hand with different fat layer thicknesses can be simulated, increasing the difficulty of puncture and achieving a better purpose of simulating puncture.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
