Application that simulates the skin

In the medical device testing industry, it is known that simulated skin is medical simulated skin, which is used to detect the physical properties of medical consumables and is a more important auxiliary device
.

Is it necessary for all testing equipment to use simulated skin? Today, Weixia Technology will make a summary for you, hoping that you have a clearer understanding
of the application of simulated skin.

Simulated skin: Simulated skin is made of polyurethane film, according to the relevant standards, the thickness of simulated skin is specified as 0.
35 mm ± 0.
05 mm, simulated skin not only has thickness but also hardness, simulated skin hardness is called Shore hardness, Shore hardness A (85 ± 10) simulated skin is qualified simulated skin
.

Simulated skin is mainly used to detect the puncture force or sharpness of various types of medical consumables, the medical consumables that need to detect the physical properties of puncture force are injection needles, suture needles, indwelling needles, acupuncture needles, microwave ablation needles and puncture devices, etc.
, so the puncture force detection of these medical consumables needs to be used to simulate the skin? The answer, of course, is not
.

According to the principle of needle tip penetration force tester, suturing needle tip puncture force tester, indwelling needle tip puncture force tester, acupuncture needle tip puncture force tester, microwave ablation needle tip puncture tester, infusion device puncture tester we can know that only the needle tip puncture force test and the indwelling needle tip puncture force test need to use simulated skin, in addition to the syringe with a needle and a pre-filled syringe with a needle Yes The puncture force test is required to simulate the skin
。
The suture needle and microwave ablation needle are made of aluminum foil, and the puncture of the infusion device is the cork
.

So not all puncture force testers need to use simulated skin in the process of testing, but simulated skin is used the most in the process of injection needle tester testing, many people artificially simulate skin is only used in the process of injection needle piercing force tester, through the above learning, do you know that simulated skin is also used for indwelling needle puncture test
.
