Diaphragm valve with reliability enhancements for atomic layer deposition
InactiveUS7021330B2Improve heat transfer performanceInhibiting condensingDiaphragm valvesOperating means/releasing devices for valvesEnhanced heat transferDiaphragm valve
A shut-off type diaphragm valve adapted for use in an atomic layer deposition system includes a valve seat having an annular seating surface that surrounds an inlet of the valve and extends radially therefrom. The seating surface contacts a substantial portion of the first side of a flexible diaphragm when the diaphragm is closed, to facilitate heat transfer and counteract dissipative cooling of the diaphragm, thereby inhibiting condensation of a medium flowing through the valve passage. The seating surface is preferably flat and smooth, to prevent shearing of an elastomeric diaphragm. For a plastic diaphragm, a ring-shaped seating ridge may extend from the seating surface to cause localized permanent deformation of the diaphragm and enhanced sealing, while still allowing a substantial portion of the diaphragm to contact the seating surface for enhanced heat transfer. Valve speed enhancements and other reliability enhancing features are also described.

Medical treatment system and methods using a plurality of fluid lines
ActiveUS20130165847A1Prevent slight movementReduce noiseFlexible member pumpsPipe heating/coolingControl systemPeritoneal cavity
A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include a control system that can adjust the volume of fluid infused into the peritoneal cavity to prevent the intraperitoneal fluid volume from exceeding a pre-determined amount. The control system can adjust by adding one or more therapy cycles, allowing for fill volumes during each cycle to be reduced. The control system may continue to allow the fluid to drain from the peritoneal cavity as completely as possible before starting the next therapy cycle. The control system may also adjust the dwell time of fluid within the peritoneal cavity during therapy cycles in order to complete a therapy within a scheduled time period. The cycler may also be configured to have a heater control system that monitors both the temperature of a heating tray and the temperature of a bag of dialysis fluid in order to bring the temperature of the dialysis fluid rapidly to a specified temperature, with minimal temperature overshoot.
