Continuous pressure on the reagent bed causes the bed to compact as it erodes when purified water is passed through the housing. The pressure ensures complete and even dissolution of the reagents. Through dry storage and simple dissolution, even in a home, the invention enables a wider variety of solution constituents, including reduced acid content and the use of bicarbonate as a stable buffer component. The latter is illustrated in a double-bed embodiment, where bicarbonate is stored separately from calcium or magnesium salts within a single housing.Type: GrantFiled: July 18, 2001Date of Patent: July 30, 2002Assignee: PRISMedical CorporationInventor: Michael A.

Patent number: 6398771Abstract: A flexible transparent container for improved storage of oxygen sensitive parenterally administerable agents comprising an inner, primary container enclosed in a substantially oxygen impermeable outer envelope with an oxygen absorber, capable of consuming essentially all residual oxygen after the outer envelope is sealed, and for sufficient period also the oxygen penetrating said envelope. The inner container is made of a polypropylene containing flexible polymeric material compatible with lipophilic agents capable of forming both permanent and peelable seals, while the envelope is made of a substantially water impermeable flexible multilayered polymeric material comprising a first outer substantially water impermeable polymeric film with oxygen barrier forming capacity, assembled with a second, inner polymeric film with a supplementary oxygen barrier forming capacity. The container essentially maintains its characteristics after being subjected to sterilization by steam or radiation.Type: GrantFiled: October 19, 1999Date of Patent: June 4, 2002Assignee: Pharmacia ABInventors: Bo Gustafsson, Stefan Lundmark, Kjell Berglund, Cathrine Brooling, Otto Skolling

Patent number: 6399110Abstract: A neutral glucose-containing preparation with excellent stability and a near physiological pH, as a transfusion preparation with minimal glucose degradation by-products and a greatly reduced formic acid content; specifically, a glucose-containing preparation comprising separately housed first and second solutions, the first and second solutions satisfying the following conditions: (a) the first solution contains 2-50% glucose, and its pH is adjusted to 3-5 with an organic acid buffer solution; (b) the second solution contains an alkalizing agent, and has a pH value of 8-13 as a pH adjustor for the first solution; and (c) the glucose concentration is 1-15% in the preparation solution obtained by mixing the first solution and second solution, and the pH of the solution is in a range of 6-8. It is used particularly as a peritoneal perfusate, such as a perfusate for Continuous Ambulatory Peritoneal Dialysis (CAPD).Type: GrantFiled: April 27, 2000Date of Patent: June 4, 2002Assignee: Shimizu Pharmaceutical Co., Ltd.Inventors: Takumi Kikuchi, Kouichi Hirano

Patent number: 6364864Abstract: Containers and methods for making containers are disclosed. The containers include a chamber and a pouch fixed within the chamber. During manufacture, the open edges of the pouch are sealed between the walls of the container by a seal defining, in part, the peripheral edge of the chamber.Type: GrantFiled: June 3, 1999Date of Patent: April 2, 2002Assignee: Baxter International Inc.Inventors: Mahmood Mohiuddin, George D. Cimino, Derek J. Hei

Patent number: 6358236Abstract: A device is provided for reconstituting a lyophilized or powdered medicament such as blood factor VIII which must be reconstituted just prior to use, such as by introduction of a sterile fluid from a syringe, which comprises a housing having an upper section capable of receiving a syringe and a lower section capable of receiving a vial containing the medicament in co-axial alignment with the syringe, a middle section connecting the upper and lower sections which has a central aperture which forms a passageway for fluid transfer between the syringe and the vial, and a hollow vented spike which extends downwardly from the central aperture for a length sufficient to ensure that the lower end of the spike will pierce the seal and enter the interior of a vial housed in the lower section of the device. The invention is advantageous because the vented opening in the spike will allow for an equalization of the pressure after the piercing of the vial by the spike which will facilitate the use of the device.Type: GrantFiled: August 6, 1998Date of Patent: March 19, 2002Assignee: Baxter International Inc.Inventors: John Mark DeFoggi, Arnold Bilstad, Ingrid McPhilliamy
