Reproductive puncture and egg retrieval needle toughness tester automatically tests Shanghai Chengwei

Reproductive puncture and egg retrieval needle toughness tester Detailed introduction: The tester adopts a 7-inch color LCD screen, and the Chinese menu displays: tube wall type, bending angle, nominal specification, distance between fulcrum and action point, and bending times
.

The program is set by the PLC programmable controller, and the test is automatic
.

The working principle of the medical needle tube (needle) toughness tester is to fix one end of the needle tube, apply a force from the fixed point to the needle tube with a specified span, first bend it in one direction and then in the opposite direction by a specified angle, and repeat the bending regulations.
The experimental operation steps are as follows: 1.
Take an appropriate amount of injection needle, and fix a section of the needle body firmly on the fixture; 2.
Fix one end of the needle firmly on the fixture, and adjust the corresponding needle tube according to Table 3.
The specified span load selects the following bending angles, normal wall 25°, thin wall 20°, and ultra-thin wall 15°
.

3.
Apply a large enough force at the specified span position, apply the force 20 times in both directions at a frequency of 0.
5Hz, and visually observe the breakage of the needle tube
