Patent number: 6368311Abstract: Featured is a device for draining fluids and/or gas from body cavities, including at least a pressure control chamber and a collection chamber being fluidly coupled by a one-way valve thereby establishing a waterless seal between the collection chamber, including the patient, and the suction source. The pressure control chamber also includes a waterless suction pressure control regulator that controls and maintains the suction pressure at or about a selected value. Preferably, the regulator includes a spring operated valve. The device also includes a vent path arrangement having an intermediate chamber and at least two passages that are perpendicular to two adjacent surfaces within the intermediate chamber. The two passages and intermediate chamber are arranged so liquid in the collection chamber does not flow and contaminate the upstream portions of the device when the device is resting on its front side or backside.Type: GrantFiled: September 28, 1999Date of Patent: April 9, 2002Assignee: Deknatel Technology CorporationInventors: Michael A. Valerio, Trinh Phung, Anthony R. Carlone, Victor E. Santos, Lawrence F. Travers

Patent number: 5848714Abstract: A rack for holding a surgical suture includes a first base having a base connector that can releasably engage a mating base connector of a second base. The rack includes a tray attached to the first base for rotation with respect to the first base. The tray has at least one suture-holding section with resilient clips and bosses to retain a surgical sutures in the suture-holding section. The tray has a pin which defines a rotatable axis and the first base has a connector that engages the pin for releasably connecting the tray to the first base. An array of suture-holding racks includes a first rack having a base with a base connector engaging a mating base connector of a base of a second rack. The first base can be attached to up to four adjacent bases.Type: GrantFiled: December 23, 1996Date of Patent: December 15, 1998Assignee: Deknatel Technology CorporationInventors: David C.

Patent number: 5769214Abstract: The invention features a suture pack including a suture having needles at its ends and a pledget between the ends. The suture can be removed from the pack by pulling on one of the needles without becoming tangled on itself or on other sutures that preferably also are included in the pack. The suture package includes a support having a first retainer holding one of the needles, a second retainer holding the other needle, and a third retainer holding the pledget separately from either of the needles. The first retainer is positioned above the second and third retainers and the third retainer is offset horizontally from the second retainer. The support may also include a fourth retainer, positioned below the second retainer for holding the suture. Preferably the first, second and fourth retainers are vertically aligned.Type: GrantFiled: October 22, 1996Date of Patent: June 23, 1998Assignee: Deknatel Technology CorporationInventor: Catherine Zatarga

Patent number: 5507734Abstract: An apparatus for draining fluids, for example, from a chest or pleural cavity, includes a collection chamber for collecting fluids through an inlet port for entry of the fluids. Also included is a dry or waterless suction control chamber in fluid communication with the collection chamber for regulating the degree of vacuum imposed in the collection chamber. If desired, a seal chamber can also be provided between the dry suction control chamber and the collection chamber so as to prevent any ambient or atmospheric air from passing into the collection chamber. The suction control chamber has a first inlet which is coupled to a suction source and a second inlet communicates with the ambient. A waterless regulator is provided for regulating the degree of suction imposed in the collection chamber at a plurality of predetermined preset levels of suction. This regulator is positioned between the suction inlet and the ambient inlet.Type: GrantFiled: April 1, 1994Date of Patent: April 16, 1996Assignee: Deknatel Technology CorporationInventors: Frederick A. Everett, Jr., Quinton J. Farrar

Patent number: 5318556Abstract: A bag for transferring fluid from a source of fluid to a fluid delivery system including three sheets of flexible material joined to form first and second adjacent compartments. Fluid is transferred into the first compartment via a perforated tube connected to the fluid source at a first end. The tube extends into the first compartment and is further connected to the fluid delivery system at a second end. The second compartment may be selectively inflated to exert force on the first compartment and control the rate of fluid flow through the tube to the delivery system.Type: GrantFiled: April 9, 1993Date of Patent: June 7, 1994Assignee: Deknatel Technology CorporationInventors: John M. Avallone, Michael A. Valerio

Patent number: 5318510Abstract: A collection device for receiving, collecting and returning blood from a body cavity, includes a housing for collecting the blood which has an inlet for fluid communication with the body cavity, a first outlet for returning blood to the body and a second outlet for coupling to a suction source. The collection device also includes a flow member which is configured and dimensioned so as to be disposed within the housing and so as to direct at least a portion of the blood entering through the inlet into a first predetermined direction and the remaining portion of the blood entering through the inlet and the first directed portion of blood in at least a second predetermined direction within the housing. The flow member can be a plate with ribs thereon to divert the flow of blood along the direction of the ribs. The collection device can also include a filter assembly positioned within the housing and about the plate so as to filter and defoam the blood before exiting from the housing.Type: GrantFiled: June 11, 1991Date of Patent: June 7, 1994Assignee: Deknatel Technology Corporation, Inc.Inventor: Bruce C.
