Patent number: 10350338Abstract: The illustrative embodiments described herein are directed to apparatuses, systems, and methods for managing liquid flow associated with a tissue site that involves using reduced pressure to control fluid flow. In one instance, an apparatus includes a first valve and a second valve in fluid communication with a reduced-pressure source. The valves are movable between an open position and a closed position and are operable to change flow status (open to closed or vice versa) based on a presence of reduced pressure. At least one of the first valve or the second valve is in the closed position to obstruct a flow of a liquid while the other is in the open position. The apparatus also includes a reservoir fluidly coupled to the first valve and the second valve. Other systems, methods, and apparatuses are presented.Type: GrantFiled: April 3, 2017Date of Patent: July 16, 2019Assignee: KCI Licensing, Inc.Inventors: Aidan Marcus Tout, Christopher Brian Locke

Patent number: 10342413Abstract: The present disclosure is for an endoscope assembly comprising an endoscope and a disposable sheath cover. The endoscope comprises an illumination window adjacent to an observation window situated along a lateral side of a distal end portion, and an elongated slot to accommodate biopsy instruments. The sheath further comprises an end cap fitted around the end portion of the endoscope with a capsule secured to its inner wall. When the end cap engages the endoscope, the capsule is ruptured to release a transparent liquid immersing the illumination window and the observation window. A soft connector is bonded to the end cap covering the elongated slot, and to an outer surface of a biopsy channel. The soft connector further comprises an opening allowing the biopsy channel to pass through. The sheath can accommodate air/water tubes, and is secured onto the shaft of the endoscope via a cuff.Type: GrantFiled: April 14, 2016Date of Patent: July 9, 2019Inventors: Kerang Jiang, Xiangyang Wu, Zhenyu Zhou, Chong Chen, Jian Zhang, Ming Xu
