Technical parameters of the guide wire bending resistance tester

The intravascular catheter is mainly composed of a needle, a guide cannula, a catheter sheath, a guide wire and a dilator, according to yy0450.
1-2003 disposable sterile endovascular catheter accessories standard, how is the anti-bending failure test of the guide wire carried out? Test principle The test part of the guide wire needs to be repeatedly subjected to reverse bending and straightening before it can check for defects and damage

The test instrument professional YY0540-C guide wire bending performance tester fully complies with the standard intelligent manufacturing, and ARM, Linux technology is guaranteed
.

Install the fixtures and instruments, set the parameters, you can test with one click, and report
out.

YY0540-C Conductive Wire Bending Resistance Tester Parameter Settings: Nominal Specifications: Any input
of all specifications.

Bending angle: 0-180 degrees
set arbitrarily.

Test accuracy: ± 0.
1 degrees; Bending frequency: 0.
1 times / min ~ 20 times / min, arbitrarily adjustable loading cylinder diameter: 20D, according to the standard configuration, easy to replace (D is the diameter of the guide wire).


Cylinder spacing: 21D~ 23D, convenient and adjustable; Number of tests: Arbitrary settings (destructive experiments) Number of experiments: 0-100 times of single two-way force application any setting
.

Details of the test on the bending resistance of the guide wire: 1.
Select the head end of the guide wire as the test section, and the test section includes the core wire part
of about 5 mm from the core wire end.

2.
Bend this part of the tip of the guide wire around a cylinder of the test device and wrap it around the second cylinder in the opposite direction.
3.
Remove the guide wire from the cylinder, make it straight, and repeat the bending and straightening steps, a total of 20 cycles
.

Check for defects and damage
caused by the bending process.

Also check for peeling marks
of the coated guide wire coating.

4.
Intermediate section guide wire test 5.
Select the part of the guide wire that does not include the tail end or head end, and perform the test step
.
