Flow and pressure tester in catheter power injection Instrument detection principle-Shanghai Chengsi

Flow and pressure tester detection principle in catheter power injection: the catheter is connected to the actual or simulated connection line by the catheter seat or its adjacent end.
The connection line is then connected to a constant pressure device filled with injection or simulated injection
.

The pressure of the pressure source is set to the product's recommended syringe pressure limit, while the system flow rate should be measured
by a mass balance or other suitable method.

The peak pressure at the conduit population should also be recorded
through an online pressure sensor.

It adopts 7-inch Velon Tong touch screen
.

The instrument is composed of a flow valve (high pressure liquid pressure source), a pressure system specified by the standard, etc.
, using a special pneumatic hydraulic pipeline to ensure that the components have no leakage, digital display of liquid high pressure, with zero point correction, accuracy correction and overrange alarm function, the use of mechanical measurement of flow, high
flow control accuracy.

(with water bath box) implementation standards: fully meet the requirements of Appendix G in YY0285.
