Patent number: 8328769Abstract: A pressure actuated flow control valve for an infusion catheter permits gravity flow of a liquid through the catheter and into a patient while resisting back flow of blood from the patient and into the catheter. The valve has a hemispherical body with an outstanding circumferential flange and a normally closed, diametric slit. The slit is longer on the convex outer surface than on the concave inner surface. Dome thickness diminishes in the area adjacent the slit, reducing total apical deflection upon collapse of the slit toward the concave surface. An inner orthogonal rib biases the slit closed. Upon application of a predetermined pressure, the slit opens toward the concave surface to permit forward fluid flow. At lower pressures, the slit closes to check fluid flow. Greater reverse pressure is required to collapse the slit toward the concave surface to permit reverse fluid flow.Type: GrantFiled: November 14, 2011Date of Patent: December 11, 2012Assignee: Nexus Medical, LLCInventors: W.

Patent number: 8221363Abstract: A luer activated device includes an inlet adapted to receive a male luer, an outlet associable with a fluid flow system, and a fluid flow path therebetween. The flow path is defined by an elastomeric flow controller extending between the inlet and outlet and maintained in a tensioned state. When a male luer is inserted into the inlet, some of the tension in the flow controller is relieved, allowing the flow path to deform and change in volume. The flow path is adapted such that the change in volume results in no net fluid displacement or minimal positive fluid displacement when the male luer is inserted into the inlet. Other aspects include tensioned flow controllers having a plurality of sealing layers for the inlet and methods of manufacturing valves having a tensioned fluid flow controller.Type: GrantFiled: October 18, 2006Date of Patent: July 17, 2012Assignee: Baxter Healthcare S.A.Inventor: Steven C.

Publication number: 20120179117Abstract: One embodiment of a blood transfusion device includes a drip chamber (10) comprising a bottom outlet (113); a filter (40) fixedly disposed in the drip chamber (10); and a float regulator (20) moveably disposed in the drip chamber (10) under the filter (40). the float regulator (20) comprising an inverted upper cup (21) including a top projection (212), a lower cup (22) secured to the upper cup (21), and a suction cup (23) secured to an underside of the lower cup (22). An inner diameter of the upper cup (21) is greater than an outer diameter of the lower cup (22). The projection (212) contacts an underside of the filter (40) when blood from a blood bag (90) sufficiently fills the drip chamber (10). The suction cup (23) falls to permanently close the outlet (113) when blood in the drip chamber (10) completely drains.Type: ApplicationFiled: January 7, 2011Publication date: July 12, 2012Inventor: Hsien-Tsung WANG

Publication number: 20120172819Abstract: The magnetically sealed intravenous access valve is an implantable port and valve for vascular access. The magnetically sealed intravenous access valve includes a housing and a pair of hollow tubes provided for interconnection and communication with the patient's blood vessel. Each tube is partially slidably received within a lower portion of the housing. A hollow key is used to selectively open and close the valve and also to inject medication into the patient's blood vessel. The hollow key is removably received within channels formed through a retainer and a rotatable obturator so that the lower end of the hollow key releasably engages the obturator. Selective rotation thereof allows eccentric spout formed in the obturator to align with an eccentric aperture formed in a valve plate. Fluids flow through the hollow key, the aligned spout and plate opening, the lower portion of the housing, and the opposing tubes for fluid transfer.Type: ApplicationFiled: January 3, 2011Publication date: July 5, 2012Inventor: MANUEL DUGROT

Patent number: 8211069Abstract: A luer connector including a housing with first end including a male luer tip and a second end. The connector further includes a rigid valve member having a first opened end and a second closed end and a retaining member configured to couple the valve member and the housing. The housing further includes a rigid conduit positioned within the housing and in fluid communication with the second end of the housing, the rigid conduit adapted to engage the first opened end of the valve member. The housing including a first internal volume when the valve member is in a first position and a second, smaller volume when the valve member is in a second position.Type: GrantFiled: September 29, 2010Date of Patent: July 3, 2012Assignee: ICU Medical, Inc.Inventor: Thomas F. Fangrow, Jr.

Publication number: 20120157933Abstract: A gland member within a medical valve is configured to have a substantially consistent or enlarging internal volume as the valve transitions from a closed mode to an open mode. The valve has a housing forming an interior containing a flow path, and a stationary post member within the interior. The post member has a lumen that is a part of the flow path. The lumen has an opening to the interior of the housing. The valve further includes a gland member circumscribing the post member to produce a variable volume region formed at least in part between the gland member itself and the post member. The variable volume region is a part of the flow path, while the gland member occludes the post lumen opening when in the closed mode. The variable volume region has an open volume that is no less than its closed volume.Type: ApplicationFiled: December 20, 2011Publication date: June 21, 2012Applicant: NYPRO INC.Inventors: Brian L. Newton, Andrew L. Cote, SR., Charles F. Ganem, David B. Woyak, Richard T. Boisjoly

Patent number: 8202266Abstract: Equipment for use in changing a catheter, preferably of the type used for drainage of the urinary tract. The urinary catheter is used as an aid in emptying the urinary bladder in conditions where this cannot be done in the normal manner. The equipment of the present invention includes a sleeve mounting unit which is mounted to an indwelling catheter, and which has a branch member formed in one piece therewith and extending at an acute angle therefrom, for reception of an elongated sleeve having a longitudinal slit. The sleeve is positioned on the branch member and then progressively advanced onto the catheter, causing the slit to become enlarged as the sleeve surrounds the upstream portion of the catheter in a yielding manner. The catheter may then be quickly removed through the sleeve and a new catheter inserted in its place.Type: GrantFiled: May 24, 2006Date of Patent: June 19, 2012Assignee: Urological ASInventor: Knut Eilert Karlsen

Patent number: 8197452Abstract: A vascular access device may include a body and a layer of the body that communicates with a pathogenic environment to discourage adhesion of a pathogen to the layer and thus repress pathogenic activity. A method of repressing pathogenic activity in a vascular access device includes providing the device with a body, and coating the body with a layer that discourages adhesion of a pathogen to the layer.Type: GrantFiled: July 26, 2007Date of Patent: June 12, 2012Assignee: Becton, Dickinson and CompanyInventors: Weston F. Harding, Austin Jason McKinnon, Mark A. Crawford, Lantao Guo, Glade H. Howell, David Ou-Yang

Patent number: 8197448Abstract: A device for retaining and dispensing a free-flowing substance includes a syringe-like retaining body (12) in which a retaining space (46) is formed. A displaceable piston (22) is axially introduced into the retaining space (46) and the retaining body (12) is provided with a dispensing nozzle (18) on its front end facing away from the piston (22). A locking pin (36) through which at least one transverse channel (44) passes, with an axial channel (42) branching off therefrom, is provided on the inside of the dispensing nozzle (18). In a closed position of the locking pin (36), a flow connection between the retaining space (46) and the transverse channel (44) is blocked. In an activation position of the locking pin (36), the transverse channel (44) is connected to the retaining space (46), so that the free-flowing substance can be dispensed from the retaining space (46) via the transverse channel (44) and the axial channel (42).Type: GrantFiled: March 9, 2011Date of Patent: June 12, 2012Assignee: Sulzer Mixpac AGInventor: Alberto C.
