Tip sharpness polyurethane film

Simulated skin:
It is also used for puncture test of indwelling needle, infusion needle or biopsy needle. It is the product of domestic production and supply of major testing institutions. This product conforms to the provisions of GB 15811 standard and is actually used by the major medical equipment supervision bureaus in China
Simulated skin material
Materials: polyurethane membrane;
Thickness: 0.35mm ± 0.05mm;
Hardness: shore A85 ± 10;
The exposed area: (after reinforcement) is equal to? 10 mm.

Puncture force test procedure:
The needle and simulated skin were placed at 22 ℃± 2 ℃ for at least 24 hours and tested at the same temperature;
Clamp the simulated skin of appropriate size on the fixture without any obvious tensile or compressive force applied to the simulated skin.
The tested needle is installed on the equipment, its axis is perpendicular to the surface of the simulated skin, and the needle tip points to the center of the circular puncture area.
Set the movement speed to 100 mm / min
Start the test device.
In the process of puncturing on the membrane, sharp value or force / displacement diagram were measured at the same time.
