Title: Teardrop shaped pressurizing apparatus
Inventor: FORD DIXON A
IPC: A61M5/152
Filed: 1997-03-25
Abstract: A pressurizing apparatus for pressurizing fluid contained in a patient fluid bag is described which has a novel teardrop pressurizing chamber. The pressure apparatus includes a door and base which each have complimentary teardrop cavities formed therein. When the door is in the closed position over the base, the teardrop pressurizing chamber is formed. A teardrop bladder bag is located interior to the base and can be inflated to apply pressure to a patient fluid bag. A regulator allows adjustment of the desired pressure. A gauge allows monitoring of the pressure. A valve allows the pressurizing device to be turned on and off. The teardrop pressurizing chamber allows the pressurizing apparatus to come up to pressure in a more expeditious manner. The conformance of the pressurizing means to the teardrop pressurizing chamber also adds to the efficiency of the pressurizing of the patient fluid bag and, additionally, allows for uniform pressure throughout a procedure.

Inventor: LEA PETER
IPC: B01L3/00
Filed: 1998-11-16
Abstract: A device for separating fluid from a biologic sample when the sample has a fluid and non-fluid component. The device is a point-of-care device through which data may be electronically collected and electronically transmitted for further evaluation. A method for separating fluid from a biologic sample is provided wherein the method comprises the step of bringing the fluid sample in fluid contact with the microspheres such that the fluid component moves by capillary action between the microspheres along capillary channels formed by the spaces between the spheres and leaving, for example, a cellular fraction behind. In the device of the present invention, the step of separating the fluid may be combined with other assay techniques for detecting and/or measuring one or more analytes which may be present in the fluid sample such as immunoassays and chromatographic assays. These may be further combined with groups of microspheres for use in the analyte detection step as well as the separation step whereby the microspheres act as labels for the analyte or as a source of label for the analyte.

Title: Plate diffuser for treating comminuted cellulosic fibrous material
Inventor: PROUGH JAMES R
IPC: D21C9/04
Filed: 1999-05-13
Abstract: The problems of non-uniform treatment of paper pulp that may be caused by differential flow velocities within a vessel, channeling, and/or disruption of the pulp flow, are substantially eliminated by providing a non-circular cross-section substantially atmospheric pressure vessel with at least one screen surface, and typically a liquid introducing device. The vessel, screen surface, and liquid introducing device are constructed and positioned with respect to each other so that during the treatment of a pulp slung the slurry has substantially uniform width in a treatment zone, and there is substantially uniform resistance to the flaw of slung over the screen surface over any particular cross-section of the vessel in the treatment zone, and its consistency varies less than fi% in the treatment zone (e.g. between 8-14%). The screen surface may comprise substantially vertical screening portions vertically spaced by non-screening portions, and the vessel wall may bulge out at the location of the non-screening portions so as to provide a slurry width at the bulges at least five percent wider than at the screening portions. The vessel may have a substantially race track shape in cross-section at the treatment zone, and the slurry width may form an annulus in the vessel, the annulus being substantially uninterrupted in the treatment zone (there being no arms or like structures which disrupt the flow). The screen surface may be rotated 5-30%, or oscillated or vibrated horizontally (transverse to pulp movement) to minimize plugging.
