Patent number: 8636721Abstract: A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.Type: GrantFiled: November 22, 2004Date of Patent: January 28, 2014Assignee: Henry M. Jackson Foundation For The Advancement of Military Medicine, Inc.Inventors: Hasan Alam, Peter Rhee, Emily Rhee

Patent number: 8632513Abstract: When a patient is fitted with an external gastrostomy connection to the stomach, ingested food can be removed through the gastrostomy connection using a pump-based or siphon-based system to achieve weight loss. The process of removing ingested food can be improved by alternating the infusion of liquid into the stomach with the removal of material from the stomach. Optionally, stomach acid may be captured and returned to the stomach. Optionally, nutritional supplements or medicines may be added to the infused liquid. Optionally, a flush mount connectorized system with a built in valve may be used to simplify the interface with the gastrostomy hardware that remains installed in the patient. Optionally, the system may be configured to disable itself from further use after a triggering event (e.g., the passage of time or a predetermined number of uses) has occurred.Type: GrantFiled: April 1, 2011Date of Patent: January 21, 2014Assignee: Aspire Bariatrics, Inc.Inventors: Dean Kamen, Kevin L.

Patent number: 8608722Abstract: The present invention relates to a container for anal irrigation. In particular it relates to a rigid container which is easy to operate and which easily is transformed from a storage configuration to a ready-to-use configuration. In one aspect the invention relates to a container for an anal irrigation system. The anal irrigation system comprises an anal probe; a reservoir for holding an irrigation liquid (e.g. water); a pump mechanism for pumping a fluid (e.g. air) into the reservoir; and a liquid tube connecting the reservoir with the anal probe. The container comprises an outer chamber wall, defining at least partly the outer dimensions of the container and an inner chamber wall arranged within the outer chamber wall, said outer chamber wall and inner chamber wall defining the reservoir. This provides a reservoir having a small surface area when filled with irrigation liquid. Thus only a low pressure is necessary to evacuate the irrigation liquid from the reservoir and out through the anal probe.Type: GrantFiled: September 18, 2008Date of Patent: December 17, 2013Assignee: Coloplast A/SInventor: Preben Luther

Publication number: 20130296816Abstract: A method and apparatus are disclosed for providing negative pressure at a wound site. The apparatus includes a suction pump for generating negative pressure, a negative pressure reservoir, a valve element arranged to selectively provide a fluid communication path between the reservoir and the wound site while a negative pressure in the negative pressure reservoir is greater than a threshold negative pressure, to thereby provide a desired negative pressure at the wound site, and wherein in response to a pressure in the negative pressure reservoir decreasing to the threshold negative pressure, the suction pump is operable to re-establish an initial negative pressure in the negative pressure reservoir.Type: ApplicationFiled: September 16, 2011Publication date: November 7, 2013Applicant: SMITH & NEPHEW PLCInventor: Bryan Greener

Patent number: 8540688Abstract: A portable device (2) to generate a vacuum for the medical treatment of wounds on the bodies of humans or animals has a vacuum-producing suction pump (90) in a first housing part (4) of the device and a vessel (10) for receiving body liquids. Vacuum is applied for vacuum communication between the suction pump (90), the vessel (10) and a suction tube (82) leading to the body. A pressure sensor (94) measures the pressure in a tube section (88) and a programmable electronic control unit (100) controls the suction pump (90) in dependence on pressure values measured by the pressure sensor (94). The electronic control unit (100) deactivates the suction pump (90) if a rate of change in pressure (?p/?t) detected by the pressure sensor (94) exceeds a defined threshold value toward decreasing vacuum.Type: GrantFiled: May 11, 2012Date of Patent: September 24, 2013Assignee: Paul Hartmann AGInventors: Axel Eckstein, Juergen Hofstetter

Patent number: 8529529Abstract: A placental blood extractor consists of an outside box having plurality of plastic bags for compressing the placenta and mounted to the top of the box. The lower part of the box has possibility to use several different circularly movable plates for mechanically facilitating the flow of the blood in the collecting veins on the fetal side of the placentas toward the central main umbilical cord vein. The box has an opening in the central lower part of the box and the lower area mechanical tray for the umbilical cord to exit the box. Blood is collected from umbilical cord and is to be collected into commercial collection bags. The area of the bag for collection of blood may be under negative pressure to facilitate the collection of blood but also gravity force may be used for that purpose. Both, the first part with the compression chambers as well as the second part, the Collector of Blood have pumps and manometers controlled by computer in their operations.Type: GrantFiled: September 28, 2010Date of Patent: September 10, 2013Inventors: Branimir L.
