Catheter bending resistance test device
Product introduction
The tester is composed of a programmable controller, a touch screen, a force sensor, a transmission device, an airborne printer, etc. It provides a menu display in both Chinese and English, and has a test mode for automatic operation of various parameters set by man-machine dialogue. Test control range includes: nominal capacity, core rod displacement, print setting, test, up, down, time, calibration, verification and other function Settings. With the on-board printed test, the test load and sliding data (starting force, average force, maximum thrust) can be displayed in real time. Automatically judge the test results, start the automatic buzzer alarm if unqualified, and print out the test data and results by the printer for analysis.
Test principle
The loop circumference of the catheter is expressed as the bending length, and the flow rate of the catheter drainage cavity and the irrigation cavity is measured under the bending length, so as to reduce the initial flow rate of the corresponding cavity after the flat catheter is placed by 50%.
