Abstract
The present disclosure relates to the technical field of medical devices, and in particular to a method for leak testing in a circuit of a medical device, a device, and a storage medium, the circuit including a reservoir bag, the method including: pressurizing the circuit; determining a compliance characteristic of the reservoir bag; stopping pressurizing the circuit, and determining a wait time of the circuit on the basis of the compliance characteristic of the reservoir bag; and determining a change in gas pressure in the circuit before and after the wait time, thereby testing whether the circuit is leaking.
Claims11
A method for leak testing in a circuit of a medical device, the circuit comprising a reservoir bag, characterized in that the method comprises:
- pressurizing the circuit;
- determining a compliance characteristic of the reservoir bag;
- stopping pressurizing the circuit, and determining a wait time of the circuit on the basis of the compliance characteristic of the reservoir bag;
