Patent number: 9126028Abstract: A medical connector providing connection between medical devices comprising a female end connectable with a male end of a first medical device, a generally circular covering portion attached to the female end that is substantially wider than the transverse cross-section of the female end, a second end configured to connect with a second medical device, a housing extending between the female end and the second end comprising a region adjacent the covering portion that is wider than an outer diameter of the covering portion. In a first stage, the female end is configured to remain stationary with respect to the housing while the male end of the first medical device is rotated onto the female end. In a second stage, the female end is configured to rotate with respect to the housing to inhibit disconnection of the male end of the first medical device.Type: GrantFiled: April 17, 2013Date of Patent: September 8, 2015Assignee: ICU Medical, Inc.Inventors: Thomas F. Fangrow, George A. Lopez

Patent number: 9109721Abstract: An apparatus for filtering water has an interface and a filtration/purification canister removably mountable onto the interface. 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. The interface provides for water boiler expansion pressure relief, while guarding against any water contaminated downstream of the apparatus from backflowing into the filtration/purification canister and contaminating the portion of the filtration/purification canister downstream of the filter/conditioning/purifying medium held within the filtration/purification canister and thereby causing water exiting the outlet port of the filtration/purification canister to be contaminated.Type: GrantFiled: September 14, 2012Date of Patent: August 18, 2015Assignee: GENERAL ECOLOGY, INC.Inventors: Richard T. Williams, Carl Beiswenger

Patent number: 9016319Abstract: A compact, reliable, and easily manufacture relief valve capable of resolving pressure issues within a fuel cell system and its components or devices. The relief valve comprises a valve body having a first cap, a valve housing and a center post; and an elastomeric member or sealing member contained within the valve body and being secured to the valve body at one end and forming a seal with the valve body at the other end. The seal opens in response to a threshold pressure being exceeded. In one embodiment, the elastomeric member is secured to the interior of the first cap and/or valve housing and forms a seal with the outer diameter of the center post. The elastomeric member may be supported by a reinforcing member.Type: GrantFiled: October 26, 2010Date of Patent: April 28, 2015Assignees: Societe Bic, The Commissariat a l'Energie Atomique et aux Energies Alternatives (CEA)Inventor: Paul Spahr

Patent number: 8944082Abstract: A coupler mechanism comprising plug and receptacle units sealably mates and de-mates first and second reservoirs. In the mating sequence, the plug and receptacle units are brought together so that their end-seals are pressed tightly against each other axially, thus forming a sealed barrier between the units and the outside environment. Once the face-to-face seal between the units has been established, further engagement displaces slidable seal elements laterally, thereby creating an opening between the reservoirs, the opening remaining sealed from the outside environment before, during and after mating. The sequence for demating the units is just the reverse of the mating sequence. One embodiment of the invention applies the aforementioned construction to harsh-environment electrical, fiber-optical, and hybrid electro-optical connectors.Type: GrantFiled: November 15, 2011Date of Patent: February 3, 2015Assignee: Teledyne Instruments, Inc.Inventor: James Cairns

Patent number: 8919368Abstract: A self-locking T-piece connects an attachment to a breathing gas line. The self-locking T-piece has a line section (2), a connection line (4) branching off therefrom, a movable valve body (10) with a valve disk (12), and a valve seat (14). The valve body (10) is prestressed by a spring (16) into a position to seal the connection line (4) against the line section (2), with the valve disk in the valve seat, and moves out of the sealing position when connecting the attachment to the connection line. The valve body (10) is elastically deformable such that it can be advanced through the connection line (4) and the valve seat (14), while undergoing elastic deformation, and returns to its original shape during the entry of valve disk (12) into the line section, in which it has a sufficient extension to be able to cover the valve seat for sealing.Type: GrantFiled: November 20, 2012Date of Patent: December 30, 2014Assignee: Dräger Medical GmbHInventors: Klaus Abraham, Gerd Wotha, David Michael Samways

Patent number: 8919732Abstract: An extendable pressurized fluid coupler is disclosed. The extendable pressurized fluid coupler has a guiding portion having a central fluid channel. The extendable pressurized fluid coupler further has a piston having a central fluid channel, the guiding portion and the piston having a common central axis. The extendable pressurized fluid coupler also has a drive circuit for driving the piston. The piston is extendable with respect to the guiding portion. The guiding portion is arranged for guiding the piston along the central axis. The piston is arranged for connecting the pressurized fluid coupler to a corresponding coupler having a second fluid channel, so that a fluid passage for a main pressurized fluid circuit is established.Type: GrantFiled: November 27, 2008Date of Patent: December 30, 2014Assignee: Caterpillar Work Tools B.V.Inventors: Joost Luyendijk, Edward Amelsfoort

Patent number: 8851114Abstract: A shut-off valve or connecting valve capable of connecting a fuel supply to a fuel cell is disclosed. The valve comprises a first valve component and a second valve component. Each valve component has an outer housing and a biased slidable member disposed inside the housing forming an internal seal. During the connection process, the two valve components establish an inter-component seal. Afterward, in one suitable embodiment the slidable member moves inward and opens the internal seal in the valve component to establish a flow path. In another embodiment, the slidable member moves inward and exposes a first filler and the first filler abuts a second filler in the other valve component to establish a flow path. In other embodiments, at least one valve component is sized and dimensioned to limit access to the internal seal.Type: GrantFiled: September 21, 2011Date of Patent: October 7, 2014Assignee: Societe BICInventors: Paul Adams, Andrew J.
