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.

Medical fluid cassette leak detection methods and devices

Systems and methods for device troubleshooting processes based on computational models are described. In one example, an apparatus may include at least one processor and a memory coupled to the at least one processor. The memory may include instructions that, when executed by the at least one processor, may cause the at least one processor to determine abnormal event information associated with an abnormal event active on the device, and determine, via a computational model: a diagnosis of a device problem based on the abnormal event information, and at least one resolution to resolve the device problem. Other embodiments are described.
