  • Medical fluid cassette leak detection methods and devices
    Patent number: 12427234
    Abstract: This disclosure relates to medical fluid cassette leak detection methods and devices. In some implementations, a method of detecting micro-leaks in a medical fluid cassette, the method includes decreasing a pressure between a vacuum reservoir of a medical treatment machine and a membrane of the medical fluid cassette when the medical fluid cassette is coupled to the medical treatment machine; measuring, using a flow meter, a rate of net fluid flow between the vacuum reservoir and the membrane of the medical fluid cassette; determining that the rate of net fluid flow between the vacuum reservoir and the membrane of the medical fluid cassette is above a threshold value; and in response to determining that the rate of net fluid flow is above the threshold value, causing the medical treatment machine to take a particular action.
