Test method of urinary catheter firmness separation force tester

The urinary catheter firmness separation force tester must fully comply with the requirements of YY0325-2016 standard, and the qualified catheter must be tested
by YY0325-2016 standard.

So which physical properties of the catheter is mainly used to test the physical properties of the catheter? Catheter firmness separation force tester as the name suggests is to test the separation force, the main test of the discharge tapered interface and test connector separation force, qualified products should not be separated from each other
.

Test method 1 for measuring the separation force of the discharge tapered interface assembly is connected to the discharge cone interface interface of the prescribed test connector with the discharge cone interface of the urinary catheter, and an axial pull force is applied to check whether the connection is separated
.

2 Instrument LF0325-C Urinary Catheter Firmness Separation Force Tester (Test Connector, Rigid Material Manufacturing), intelligent tester manufactured by YY0325-2016, mainly through ARM processor, Linux intelligent operating system; Install the catheter on the fixture; Touch screen set parameters, one-click test, on-board printing test report
.

Catheter Firmness Separation Force Tester LF0325-C Catheter Firmness Separation Force Tester constitutes a component (1) ARM processor, Linux intelligent operating system
.

(2) Touch screen, set parameters, one-click test
.

(3) Fixture, install urinary catheter (4) weights, test the connector connection device
.

For catheters with a size less than or equal to 3.
3 mm, the total mass of the connecting device and the weight is 0.
75 kg; for catheters with a size greater than 3.
3 mm, the total mass of the connecting device and the weight is 1 kg
.

(5) Timer (6) Airborne printer catheter firmness separation force tester LF0325-C catheter firmness separation force tester Discharge tapered interface assembly separation force test steps (fine) (1) test at (23 Shi 2) °C (2) so that the catheter discharge tapered interface and connector clean and dry
.

(3) Plug the connector into the discharge tapered interface, and the insertion depth is more than 10mm (that is, to meet or exceed the reticle on the connector
).

(4) Select a point near the connection between the excretion tapered interface and the tube body, clamp it with a fixture, hang the catheter (5) hold the weight, connect to the excretion conical interface of the catheter, gently put the weight down, until it is suspended on the catheter, keep for 1 min and observe
.

(6) Record whether the test connector is separated from
the tapered interface.
