Patent number: 7763013Abstract: A first fluid connector is provided for selective interconnection to and fluid transfer with a second fluid connector. The first connector comprises a fluid passageway, an internal member and an outer collar supportably disposed about the internal member for selective advancement and retraction relative thereto. At least a portion of the fluid passageway may extend through the internal member. The outer collar may be selectively retracted to facilitate cleaning of the internal member. In some embodiments, the outer collar and internal member may be disposed so that a distal portion of the internal member is substantially flush with or a distal portion of internal member projects beyond a distal end of the outer collar when the outer collar is in a retracted position relative thereto. To facilitate cleaning, a distal end or distal portion of the internal member may be substantially closed when the first and second connectors are disconnected.Type: GrantFiled: June 9, 2008Date of Patent: July 27, 2010Assignee: Baxa CorporationInventors: Brian Eugene Baldwin, Randall Wallace Smith, Gregory John Baldwin

Publication number: 20100185159Abstract: There is provided an enteral feeding assembly having a base and a connector. The base has a catheter with a lumen for communication with a body lumen. The base also has an opening with a predetermined shape on its proximal side that also communicates with the catheter lumen. The connector has a key configured to complement the predetermined shape of the opening in the base, which occurs desirably in one position only, so that the connector and base may be joined together. The connector is also connected to a feeding tube that provides a nutrient solution from a replaceable feeding bag. Once the connector is in position in the base, liquid may from the bag to the body lumen. Once in position, the connector may rotate 360 degrees relative to the base before being again in the installation/removal position.Type: ApplicationFiled: December 17, 2009Publication date: July 22, 2010Inventors: Alison S.

Publication number: 20100179489Abstract: A needleless luer access connector is disclosed having a septum disposed in a housing. The septum has a proximal portion with a cross section, a medial portion with a cross section smaller than the cross section of the proximal portion, and a distal portion. A longitudinal slit extends through the septum from the proximal portion to the distal portion. The septum and housing are designed so that septum will not be rotated or removed from the housing when the connector is accessed by a male luer taper. In addition, the septum and housing are designed to bias the slit at the distal portion closed and so a male luer connector does not have to extend completely through the distal portion to open the slit at the distal portion. Finally, the septum and housing are designed to minimize the amount of dead space in the connector when accessed with a male luer taper.Type: ApplicationFiled: March 19, 2010Publication date: July 15, 2010Applicant: Becton, Dickinson and CompanyInventors: Weston F.

Patent number: 7722583Abstract: A bowel management system includes a waste collection catheter having at least two distinct sections. The first section is patient proximal when disposed in the patient's rectum and has durometer hardness in the range of about 50 A to about 90 A. The second catheter section is connected to the first section and has durometer hardness in the range of about 5 A to about 49 A. A selectively collapsible, substantially spherical retention balloon is attached coaxially and exterior of the first catheter section such that the proximal-most end of the retention balloon is coincident to the proximal-most end of the first section of the waste collection catheter, the substantially spherical retention balloon having an inflated size so as to be sufficiently large enough to retain the patient proximal end of the catheter in the patient's rectum without being so large as to trigger a defecatory response in the patient.Type: GrantFiled: April 28, 2006Date of Patent: May 25, 2010Assignee: Hollister IncorporatedInventors: Jae H.
