What is the tester procedure for the needle tip puncture force tester?

Injection needle tip puncture force tester is a professional for testing the physical properties of the needle tip of the injection needle efficient precision testing instrument, will pay attention to The visha technology friends should know that when using the needle tip puncture force tester injection needle simulated skin is one
of the necessary accessories.

Today, Wiscia Technology will explain to you in detail what is the tester program of the injection needle tip puncture force tester? First of all, we review the principle of the injection needle tip puncture tester, according to GB 15811-2016 disposable sterile injection needle standard in the injection needle puncture force test and evaluation method, the principle of the injection needle puncture force test is to use the puncture force test device to make the injection needle at a specified speed, vertically through the maximum peak measured when simulating the skin to evaluate the puncture force
of the injection needle.

The exact amount of "prescribed speed" will be mentioned
in the test procedure of the needle tip puncture force tester.

The test procedure of the needle tip puncture force tester is as follows: 1.
The needle and the simulated skin will be placed at 22 ° C at least 2 ° C for at least 2 4 h, and tested
at the same temperature.

2.
According to the measuring device shown in Figure B.
1, the simulated skin of appropriate size shall be clamped on the fixture, and no obvious stretching or compressive force shall be applied to the
simulated skin.

3.
The needle will be mounted on the test device (B.
2.
1), its axis is perpendicular to the surface of the simulated skin (B.
2.
3), and the needle tip points to the center
of the circular puncture area.

4.
Set the movement speed of the test device (B.
2.
1) to 100 mm/min
.

5.
Start the test device
.

6.
In the process of puncture on the membrane, the maximum peak force or recorded force/displacement diagram is measured at the
same time.

(Note: Do not use membranes
that have been punctured in circular puncture areas.
)
How much force is used during the puncture? The recommended force value is as follows: the injection needle with a specification of 0.
3~0.
6mm should use a force value of less than or equal to 0.
7N during the test; Injection needles with a size of 0.
9~0.
9mm use a force value of less than or equal to 0.
85N during the test; Injection needles with a size of 1.
1 to 1.
2 mm use a force value of less than or equal to 1.
15 N
during the test.

Warm reminder In the injection needle physical performance test, experienced operators know that the injection needle tip piercing tester, injection needle tip rigidity tester, injection needle tip toughness tester, injection needle tip fracture force tester to detect the piercing force, rigidity, toughness, breaking force and other properties of the needle tip, but don't forget to use the injection needle to connect the firmness tester and 6% The Ruhr conical connector multifunctional tester checks the firmness of the connection between the needle holder and the needle cap and the performance
of the ruhr on the injection needle spare part.
