Shanghai Chengsi-injection needle tip puncture force tester CSI-Z017-instrument parameter analysis

Needle tip puncture force tester injection needle tip puncture force tester belongs to the needle tip puncture detection instrument, also known as medical injection needle tip puncture force detector, specially used in the syringe injection needle puncture force test, can accurately measure the sharpness of the syringe injection needle whether it fits the rules of the specification, evaluate whether the sharpness of the syringe injection needle fits the normative rules

Onboard print test data for real-time display of puncture force and peak force data
.

Test principle: the injection needle is mounted on the driving mechanism connected to the measuring device, and then the injection needle is made to pass straight through the imitation skin at a specified speed, and the puncture force
of the injection needle is evaluated by the measured large peak.

Technical parameters: pipe wall: normal wall, thin wall, ultra-thin wall three optional; Nominal specification: 0.
2~1.
6mm; Test range: 0~5N; Test speed: 50~250mm/min; Operation interface: Chinese Simplified/English; 7 inch color touch screen pressure sensor range: 0-5N analog skin material: polyurethane film material, in line with GB15811-2001 standard; Thickness: 0.
35mm±0.
05mm; Hardness: Shore A85±10; Exposed area: (after reinforcement) equal to ø10mm Printing method: Each time the test data can be printed and the average puncture force and deviation value detection method: 1.
The needle will be detected and the imitation skin will be placed at 22 °C ± 2 °C for at least 24 h, and tested at the same temperature; 2.
Clip the imitation skin of the appropriate scale on the fixture, and no stretching or compressive force shall be applied to the imitation skin; 3.
The needle will be mounted on the device, its axis is straight to the appearance of the imitation skin, and the tip of the needle points to the center of the circular puncture area; 4.
Set the movement speed to 100mm/min; 5.
Start the test equipment; 6.
During the puncture process on the membrane, the sharp value or the recording force/displacement diagram are measured at the same time; 7.
Compare the max peak in the resulting force/displacement diagram with the required rule value, and when the max peak is less than or equal to the regular value, it is determined that the puncture force of the needle is in line with the requirements
