A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.Type: ApplicationFiled: May 24, 2012Publication date: April 24, 2014Applicant: DEKA Products Limited PartnershipInventors: Kevin L.

Publication number: 20140102962Abstract: A portable water filtration bottle includes a main unit having a containing space. The main unit is provided orderly from an water inlet to a water outlet with a first cover unit covering the water inlet; a filtration tank which contains a filter and is at a side of the containing space, with the filtration tank being connected with a non-return device at a side close to the containing space; a bactericidal lamp tube device which is at another side of the containing space; and a second cover unit covering the water outlet. Accordingly, water entering from the water inlet is filtered and then flows into the containing space under a control of a check valve. Next, water is sterilized by the bactericidal lamp tube device. Therefore, users are able to drink clean water at all times and hygiene of drinking water can be improved.Type: ApplicationFiled: October 11, 2013Publication date: April 17, 2014Inventor: TIEN-CHI YAO

Publication number: 20140102985Abstract: Described are water-on-water valves for use in reverse osmosis filtration systems. The water-on-water valves are regulated by the pressure in a product line, which contains fluid from a product line of the filter module and/or the product side of a water-on-water storage tank. Exemplary valves are shuttle valves that are regulated by the pressure downstream of the product side of a reverse osmosis filter module. The valves may comprise a piston within a housing, and an end of the piston may have an enlarged diameter relative to the maximum diameter of the remainder of the piston.Type: ApplicationFiled: September 26, 2013Publication date: April 17, 2014Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Laurence W.

Patent number: 8671980Abstract: An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface.Type: GrantFiled: August 6, 2010Date of Patent: March 18, 2014Assignee: General Ecology, Inc.Inventors: Richard T. Williams, Carl Beiswenger
