摘要:
A reduced pressure treatment system (100) comprising: a manifold (104) adapted to be positioned at a tissue site; a regulated chamber in fluid communication with the tissue site to deliver a desired therapy pressure to the tissue site; a charging chamber adapted to store a charging pressure that is less than the desired therapy pressure; a passage providing fluid communication between the regulated chamber and the charging chamber; a valve body operably associated with the passage to substantially reduce fluid communication through the passage when a pressure in the regulated chamber is less than or equal to the desired therapy pressure and to allow fluid communication through the passage when the pressure in the regulated chamber exceeds the desired therapy pressure.

摘要:
An apparatus (500) is operable to communicate fluid. An exemplary apparatus comprises a housing (502) and a fluid reservoir within the housing. An actuator (504) is operationally engaged with the fluid reservoir. The actuator is operable to effect communication of fluid from or into the fluid reservoir. A sensor (530) is in fluid communication with the fluid reservoir. The sensor is operable to sense a physical parameter of fluid that is in communication with the fluid reservoir as the fluid is communicated from or into the fluid reservoir. An indicator (508) is in communication with the sensor. The indicator is operable to display the physical parameter sensed by the sensor. The apparatus may be used to inject fluid into or withdraw fluid from an implanted gastric band system or for a variety of other uses. Fluid pressure may be adjusted and sensed, and resulting data may be displayed, by a single, integrated instrument.

摘要:
A reduced pressure treatment apparatus includes a charging chamber (355) storing a first pressure less than an ambient pressure and a regulated chamber (359) storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit (275) provides fluid communication between the regulated chamber and the charging chamber. A regulator member (307) is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

摘要:
An assembly structured to Inflate a retaining or pressure cuff of a medical device including of the type associated with an artificial airway tube such as an endotracheal tube and/or tracheostomy tube and concurrently monitor pressure therein including a casing having a pressure chamber on its interior. A pump assembly is movably connected to the casing and structured to force fluid flow to the retaining cuff, for inflation, through said pressure chamber. An indicator member is disposed within the casing and is visually accessible through the casing window, wherein the indicator member is variably positionable dependent on and indicative of existing pressure within the retaining cuff. The existing pressure within the pressure chamber is substantially equivalent to that within the retaining cuff thereby facilitating the variable position of the indicator member to be indicative of pressure within the retaining cuff.
