Extracorporeal blood treatment systems and methods to detect the connection of one or more components (e.g., of an extracorporeal blood set) thereto (e.g., to one or more pressure transducers contained in the system housing) by, for example, controlling an air pump apparatus to provide air to a connection port at which the component is to be connected and monitoring pressure resulting therefrom to detect whether the component is operatively connected (e.g., based on a detected change in the monitored pressure due to the increased resistance, based on a monitored rate of decay of pressure of injected air, etc.).

Blood set component connection detection

The present invention is a wafer fixture comprising a housing body, a thrust plate, a flexure clamp, gaskets, flexure pins on an inner circumference of the housing body, locking grooves on an outer circumference of the flexure clamp, and a handle. A wafer may be placed between the gaskets of the housing body and the thrust plate. The flexure clamp may be placed over the thrust plate and secured to the housing body by rotating the flexure clamp such that locking grooves of the fixture plate mate with the flexure pins on the inner circumference of the housing body. The present invention in yet another embodiment is a wafer etch tool comprising a housing, a flexure clamp, and means for securing a wafer between the housing and the flexure clamp upon rotation of the flexure clamp within the housing.
