Patent number: 8066645Abstract: A bleed flow valve assembly for venting air from a blood pressure cuff at relatively constant pressure decrease rate irrespective of cuff size includes a multiple chamber bleed valve and a multiple position control valve operatively associated therewith. A first end chamber is connected in pneumatic communication with the cuff and pneumatically sealed from a second central chamber by a first flexible diaphragm. A third end chamber is separated from the central chamber by a second flexible diaphragm. A variable flow area opening through the second diaphragm provides a flow path for controllably venting air from the second chamber to ambient pressure when the control valve is selectively positioned to connect the third chamber in pneumatic communication with ambient pressure. Air is vented from the cuff through the first chamber in regulated response to the pressure differential between the first chamber and the second chamber acting upon the first flexible diaphragm.Type: GrantFiled: August 21, 2006Date of Patent: November 29, 2011Assignee: Welch Allyn, Inc.Inventor: Allan I. Krauter

Patent number: 7722542Abstract: A blood pressure measuring apparatus includes an inflatable sleeve socket that is capable of receiving an engagement portion of a compact gage housing having either a contained mechanical or an electronic pressure gauge. This coupling permits direct attachment to the sleeve and permitting fluid interconnection between the interior of the sleeve and the contained pressure gauge without requiring any hoses or tubing therebetween. The electronic pressure gauge is responsive to changes in pressure within the inflatable sleeve. The pressure changes can be processed and output to an integral display or can be wirelessly transmitted.Type: GrantFiled: June 5, 2003Date of Patent: May 25, 2010Assignee: Welch Allyn, Inc.Inventors: Raymond A.
