TISSUE INTERFACE DEVICE

摘要

A tissue interface device (10) suitable for positioning on or about one or more artificial openings in a biological membrane of an organism and for coupling to a monitor and control unit and a vacuum source. The tissue interface device (10) comprises a housing (100), a sensor channel (130), and a sensor (150). The housing (100) defines an orifice (120), the orifice (120) having an open inlet port (122) on the bottom end (102) of the housing (100) and a distal end (124) that is in fluid communication with the sensor channe l (130). The orifice (120) is in fluid communication with fluid that flows fro m the artificial opening formed in the biological membranes. The sensor channe l (130) is for coupling to, and fluid communication therewith, the vacuum source. The sensor (150) is positioned in the sensor channel (130) in a flow path of the fluid for sensing a characteristic of the fluid as it flows out from the artificial opening. The sensor generates a sensor signal representative thereof.
