摘要：
Self-calibrating sensor assemblies for excess body fluid drainage systems are disclosed herein. Self-calibrating sensor assemblies can include a sensor assembly engaged with a flexible interface member of a drainage catheter. The assembly includes a sensor having a body and a shaft extending from the body. A contact member is slidably mated with the shaft and coupled to the flexible interface member. A resilient member is coupled to the sensor shaft and disposed between the contact member and the body. An actuator moves the sensor between a first position and a second position with respect to the drainage catheter. In the first position the sensor is positioned to measure the pressure and/or force at the flexible interface member, and in the second position the resilient member exerts a known force on the sensor.
