Test catheter burst pressure tester precautions and safety precautions must be taken

Test Catheter Blasting Pressure Tester Precautions and safety precautions must be taken to protect test operators from the risk
of pressure system failure and fluid leakage under high pressure.

1, Clinically relevant pretreatment is used to prepare the test catheter
.

For example, pre-soak in normal saline, contact with commonly used injections, or sterilize treatment
.

2, so that the test chamber fluid temperature to (37±2)C, and maintain this temperature
during the test.

3.
Connect the catheter header to the connector and fix it securely with a locking device (if applicable
).

4.
Make sure that the gas inside the catheter has been drained with fluid, and then seal the catheter with a clip
.

5, check whether the hydraulic circuit is intact and there is no leakage
.

6.
Immerse the catheter in the circulating chamber fluid for at least 1 min before the test to achieve thermal equilibrium
.

7.
Adjust the hydraulic source so that it supplies the test catheter with a fluid rate of 1 mL/s to generate sufficient pressure
to make the catheter leak or burst.

For alternative equipment, the manufacturer should use a pressure rate to control the test equipment so that it accurately measures the static burst pressure
.

8.
Inject the fluid into the closed catheter until the catheter leaks or bursts
.

9, when the system pressurizes, record the catheter seat pressure, mark the Z high pressure that it can achieve o Shanghai Litao Automation Technology Co.
