BLOOD PUMP ASSEMBLY COMPRISING SENSOR AND SENSOR SHIELD

Japanese Patent JP2023126639

A

To provide a blood pump assembly.SOLUTION: A blood pump assembly may comprise various components such as, a housing, and a sensor configured to detect one or more characteristics of blood. In some embodiments, the sensor may be coupled to the housing, and may include a sensor membrane configured to be bent in response to change of a blood parameter (pressure, for example). The blood pump assembly may include a shield for covering at least a part of the sensor membrane, so as to protect the sensor from damage, when the blood pump assembly is inserted through an introducer, and is advanced through a vasculature of the patient, and/or the blood pump assembly is inserted into a heart in a surgical technique. For preventing dissolution of the sensor membrane by interaction with the blood of the patient, one or more protection layers may provided on the sensor membrane.SELECTED DRAWING: Figure 4
