The needle puncture force simulates the skin tester with a
5.*-inch (**0 x *0) single color LCD touch screen, which is
displayed in the Chinese menu. Nominal specification, pipe
wall, test number, pressure, upward, downward, time,
calibration.
The keyboard controls the menu on the LCD screen, and the
airborne print test data. Real-time display of puncture force
and peak force data can show maximal puncture force and F 5
peak force. The needle puncture force simulates the complete
character of the skin tester.
It is designed and manufactured in accordance with the
relevant provisions of GB****1 "disposable sterile injection
needle".
Principle:
The puncture force of the injection needle was assessed by
the maximum peak force measured at the time of the simulated
skin using a puncture force test device.
Parameters:
Nominal specification: 0.3 ~ 1.2mm;
Test range: 0.*0 ~ 5.*0N, accuracy: + 0.*1N;
Mobile speed: **0mm/min;
(presented) simulated skin: polyurethane membrane material
conforms to GB****1 standard;
Printing method: can print 8, *3 or *0 test data and average
puncture force and deviation value each time.
Net weight: *1kg dimensions: **0 x **0 * **0
(mm)
Partial list:
1. Main engine
2. Printing paper 1 roll.
3. A set of clamps.
Weight one set.
5. One-year warranty
6. Operation instructions
7. The instrument is free to upgrade service according to
national standards.
Puncture force test procedure:
Will be needle and simulate the skin in the *2 ℃ plus or
minus 2 ℃ for at least *4 h, and at the same temperature
test;
The suitable size of the simulated skin clamp on the fixture
shall not have any obvious stretching or compression force
applied to the simulated skin.
The needle is installed on the device, and its axis is
perpendicular to the surface of the simulated skin, and the
tip points to the center of the circular puncture
zone.
Set the moving speed to **0mm/min.
Start the testing device.
In the process of puncture, the maximum sharp value or record
force/displacement diagram was measured
simultaneously.
