INTRAPERITONEAL PRESSURE ("IPP") MEASUREMENT METHODS, APPARATUSES, AND SYSTEMS

Abstract:

An intraperitoneal pressure ("IPP") measurement apparatus is disclosed herein. In an example, the IPP measurement apparatus includes a transfer set or catheter that is fluidly coupled to a patient's peritoneal cavity and a pressure sensor adapted to contact the transfer set or catheter. The pressure sensor is configured to transmit output data indicative of an IPP within the patient's peritoneal cavity. The pressure sensor includes a pressure element configured to measure a pressure imparted by a fluid within the transfer set or catheter. The pressure sensor also includes a pressure amplifier having a first side that contacts a portion of the transfer set or catheter and a second side that contacts the pressure element. The first side has a greater diameter or surface area compared to the second side for amplifying the pressure signal for the IPP measurement.
