Catheter burst pressure tester CSI-Z060-2 Shanghai Chengsi - Test step measures

Catheter burst pressure tester implementation standard: YY0285.
1, YY0285.
1-2017 Main parameters: drive air pressure: 0.
3-10MPa pressure range: 0-10MPA (adjustable), boost ratio 1: 16 pressure reading accuracy ±1%, with internal cone joint main configuration: gas-liquid booster pump, protective chassis, regulator, unloading valve, hand pull valve, seismic pressure gauge, stainless steel pipeline, check valve and other box size: height 900 * width 1450mm* * inner cone Thickness 650mm incubator: shape 310-280-180mm, 15 liters; Temperatures of 8-100 degrees Celsius must be preventative and safety precautions taken to protect test operators from the risk
of pressurized system failures 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, a pressure rate should be selected 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 is pressurized, record the casing pressure and mark the maximum pressure
that it can achieve.
