Title: Method and apparatus for determining failure of pump for artificial heart
Inventor: YAMANE TAKASHI
IPC: F04D15/02
Filed: 2001-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a technique for easily determining the failure of a pump for an artificial heart, which is desired in view of the fact that the pump, particularly of the type embedded into the body, when a patient using it is in bad health, does not make it clear whether the artificial heart or another part of the body has failed. SOLUTION: For the process of determining the failure of the pump for an artificial heart, if measurement data for the specific rpm of the pump being actuated are not on a 'pressure-flow' characteristic curve in Figure 1 (a), then the geometrical failure of the pump such as damage to a blade is determined to have occurred. If the measurement data are not on a 'consumed power-flow' curve, then dysemia such as thrombosis is determined to have occurred. If the data are on both curves, a failure is determined to have occurred not in the pump but in another part of the patient's body or a connection tube, etc.
