Analog simulated skin and puncture module with analog simulated skin

Abstract

The invention relates to an analog simulated skin and a puncture module with the analog simulated skin, belonging to the technical field of medical teaching. The analog simulated skin is divided into at least one outer simulated skin layer and an inner simulated skin layer, wherein the edges of the two layers are closely fit to form a sac structure. The puncture module with the analog simulated skin mainly comprises the analog simulated skin and a base, wherein the base mainly comprises an upper cover and a lower cover; the upper cover is hollow and tightly screwed with the lower cover; the lower cover is in a depressed structure, an analog puncture liquid is stored in the depressed structure, and the lower cover is tightly screwed with the upper cover. When a needle is pulled out from the analog simulated skin, the liquid enters the sac in turn, and when the liquid in the sac is with a certain volume and pressure, the liquid penetrates outside from the outer simulated skin layer, thus the sac structure completely reduces the penetration rate of the liquid when the analog simulated skin is punctured, thus the analog simulated skin with the sac structure can be continuously punctured for hundreds of times. Thus, the quality of the products is improved on the basis of present materials, and the cost is reduced.

Description

technical field

[0001] The invention relates to a structural improvement of a teaching tool, in particular to an improvement of a simulated skin structure, and a puncture module with the simulated skin. Background technique

[0002] In some puncture medical teaching model products, silica gel is a commonly used material for simulating skin. The ratio is designed according to the different functional areas of the human body, so that the hardness and hardness of the skin at the corresponding anatomical position can be simulated. softness. However, the single-layer simulated skin made of silicone cannot maintain the state before the puncture for a long time after 10 uninterrupted punctures, so that the simulated blood or simulated abdominal effusion under the single-layer simulated skin will be punctured The holes flow out, so the corresponding simulated skin needs to be replaced frequently, so as to achieve the effect of multiple puncture training. Invisibly reduces the qual...

Examples

Embodiment 1

[0014] Embodiment 1: as figure 1 As shown, the simulation skin is divided into two layers, the outer layer of artificial skin 2 and the inner layer of artificial skin 3, the edges of the two layers are closely fitted, and a capsule 8 is formed in the middle. When the needle is inserted and withdrawn, because the existing silicone material The completed simulated skin will leak after being punctured 10 times. At this time, the liquid will first leak into the capsule 8, and only when the capsule 8 is filled with liquid and a certain pressure will it penetrate into the outer layer of simulated cortex, but because the outer layer of simulation The cortex 2 and the inner layer of simulated cortex 3 fit tightly, so that the volume of the capsule 8 becomes very small, so that the liquid is not easy to penetrate into the capsule 8 during the puncture, so as to prevent leakage. The greatly increased number of punctures improves the quality of the product, reduces the cost, and prevents...

Embodiment 2

[0015] Embodiment two: if figure 2 As shown, the simulated skin is divided into three layers, the outer simulated cortex 2, the inner simulated cortex 3 and the middle simulated cortex 4, and the three layers are closely attached to each other, and the edges of the three layers are closely fitted together to form two capsules 8 structure, when the needle is inserted and withdrawn, because the simulated skin made of the existing silicone material will leak after being punctured 10 times, at this time, the liquid will first leak into the capsule 8, when the two capsules 8 are filled with liquid and Only when a certain pressure is applied will it penetrate into the outer layer of artificial cortex, but because the middle layer of artificial cortex 4, the outer layer of artificial cortex 2 and the inner layer of artificial cortex 3 fit tightly, the volume of the capsule becomes very small, so that during the puncture This makes it difficult for liquid to seep into the bag 8, so ...

Embodiment 3

[0016] Embodiment 3: Most of the puncture products in the existing market cannot meet the requirements of multiple punctures, so that the puncture simulation skin needs to be replaced constantly. For this reason, a puncture module with the simulation skin is provided, such as image 3 As shown, it includes an upper cover 5 and a lower cover 6, and the upper cover 5 and the lower cover 6 are tightly connected by a thread 7, and the simulated skin is squeezed and fixed on the upper cover 6 by the action of the thread 7. Between the cover 5 and the lower cover 6, the lower cover 6 has a concave structure, which can store the simulated puncture liquid, so far, a puncture module with the simulated skin is formed, which can perform various puncture exercises and improve the product quality. The cost is reduced, and various puncture needs can be met.
