ANSI/AAMI-EC53: 2013/(R)2020 Flex Life Of Trunk Cable And Patient Leadwire Flex Relief
Standard & Clauses:
AAMI-EC53-1998
ANSI/AAMI-EC53:2013/(R)2020 “ECG trunk cables and patient leadwires”
Specimen Range, Application, Principle, Structure and Use Environment:
Samples and Restrictions: EGA trunk cables and patient leadwires
Application: Used to test the bending resistance of EGA trunk cables and patient leadwires when the power cord enters the appliance. To verify its reliable performance.
Principle: Use a motor to drive the fixture to flex the sample. Apply current to the soft wire to make the sample flex left and right at a certain speed and angle of ±90°. And clamp the weight at a position 6 inches away from the lead outlet end of the sample. The test will automatically stop when the equipment reaches the test times or the soft wire is short-circuited.
Equipment structure and schematic diagram:
The equipment is driven by a servo motor, and the fixture is installed in the center. And the eccentricity is adjustable. When clamping the sample, the flexing axis and the point where the cord enters the appliance can coincide as much as possible. This results in minimal lateral displacement of the cord and load.
