Patent number: 6197009Abstract: A design and method of operation are disclosed for a fluid control conduit of a blood reservoir. The venous blood inflow conduit includes a fluid control nozzle and a base. When assembled together, the nozzle and base form a trap feature which prevents reflux of air or other gas upwardly into the nozzle of the conduit. As a result, during use of the reservoir the conduit normally runs full of venous blood and turbulence of the blood is prevented. In addition, the conduit also functions to divert the downward flowing venous blood in the nozzle into the base at an optimum fluid velocity to overcome the buoyancy effect of air or gas bubbles within the blood.Type: GrantFiled: October 28, 1999Date of Patent: March 6, 2001Assignee: Jostra Bentley IncInventor: Robert Steg

Patent number: 6198106Abstract: A flexible container is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments, separated by peelable seals, in which the diluents and medicaments are stored. The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV arrangement to a patient. The seals are constructed to provide a non-linear resistance characteristic to hydraulic pressure, which causes the seal to peel open completely along its length. The container also includes a locking tab and retaining slot to secure the bag in a folded-over condition.Type: GrantFiled: November 10, 1998Date of Patent: March 6, 2001Assignee: B. Braun Medical, Inc.Inventors: Ward W. Barney, Walter A. York, Douglas G. Harvey, H. Theodore Young, Scott L. Pool, Giuseppe Sacca, Thomas R. Sakaguchi, Steven L. Smith, Noel Gharibian

Patent number: 6186998Abstract: A bag for an infusion solution has front and back wall portions each formed of a flexible plastic film and provided with a plurality of chambers which are filled with one infusion solution and another infusion solution or medicament, independently. The chambers are sectioned by a boundary portion having at least one weak seal portion which is closed by separably bonding inside surfaces of the plastic films mutually facing at the boundary portion so that the one infusion solution and the another infusion solution or medicament in the respective chambers are mixed together when the weak seal portion is opened. The weak seal portion is formed by applying a separable coating material, which provides a reduced bonding strength in a heat sealing process, on one or both inside surfaces of the plastic films mutually facing at the boundary portion and then effecting heat sealing process to the boundary portion. The separable coating material is applied in a form of a dot-pattern through a printing process.Type: GrantFiled: May 29, 1998Date of Patent: February 13, 2001Assignee: Hosokawa Yoko Co., Ltd.Inventors: Takeshi Inuzuka, Susumu Niwa

Patent number: 6183453Abstract: The invention relates to an apparatus and method for a one-handed procedure that encapsulates the connector of a blood evacuation system prior to reinfusion. The blood evacuation system comprises a separable, flexible inner bag inside an outer rigid container for reinfusing shed blood drawn from the collection chamber of a chest drainage unit. The outer rigid container includes a suction port connected to a source of vacuum for applying a negative pressure within the interstitial space between the rigid container and the inner flexible bag which causes blood to be drawn into the bag. Once the bag is filled to a desired level, it is removed from the container and suspended using a suitable suspension means within the vicinity of a patient for reinfusion. The container further includes a lid with a nest formed on the outside surface of the lid for employing a one-handed procedure for encapsulating a blood spike.Type: GrantFiled: November 19, 1998Date of Patent: February 6, 2001Assignee: Sherwood Services, AGInventor: David Rork Swisher

Patent number: 6183451Abstract: A method and article for delivery of skin care agents. Freeze-dried liposomes are used to encapsulate agents for delivery to specific cells in the skin. The applicable agents include perfumes, moisturizers, vitamins and therapeutic compounds as well as others. The agents are encapsulated in liposomes specifically selected to carry the agents to the target cells thereby increasing effectiveness and efficiency and minimizing systemic absorption. The liposomes are at least partially freeze-dried to improve shelf-life and improve delivery to the skin. After freeze-drying, the liposomes are deposited on or in a fabric-like pad. The liposomes are rehydrated either immediately prior to application to the skin or on the skin using natural moisture or a hydrating solution. An applicator is also provided to secure and hold the impregnated pad during use. The applicator may provide steam or vapor to rehydrate the liposomes during application.Type: GrantFiled: December 3, 1998Date of Patent: February 6, 2001Inventors: Thomas L. Mehl, Sr., Nardo Zaias

Patent number: 6168581Abstract: A drop dispenser having a sleeve carrying a closure and resilient dosage receiving fitting. The sleeve is treadably mounted an a fluid containing container having a nipple thereon. The closure on the sleeve has a configuration corresponding to the configuration of the nipple for sealing the nipple in the closed position. The fitting is filled with fluid from the container by turning the sleeve in a direction away from the closed position on the nipple to an open position to thereby establish fluid communication between the container and fitting. The fluid is dispensed from the fitting by squeezing the fitting after the closure has been returned to the closed position on the nipple, thereby preventing fluid from flowing from the resilient fitting back into the container. Cooperating stop members are provided between the sleeve and bottle neck to limit the movement of the sleeve relative to the bottle neck.Type: GrantFiled: February 9, 1999Date of Patent: January 2, 2001Assignee: Comar, Inc.Inventor: John D.
