Patent number: 5935083Abstract: A device for measuring body fluid pressure, such as blood pressure, muscle compartment pressure, and spinal column pressure, is herein described. An invasive implement is inserted into a body area, and a fluid path extends from the body area into a fluid channel in the device. A valve is used to control the flow of fluid through the device and a pressure sensor is placed adjacent to the fluid channel, with the pressure sensor and/or a sealant gel forming a portion of the fluid channel. With the valve closed, pressure builds in the fluid channel and the pressure sensor detects the resulting pressure, and a pressure transducer and supporting electronics converts and communicates the pressure measurement. With this device the pressure sensor can detect pressure without contacting the fluid, so therefore a pressure can be taken with a minimum of fluid extraction. If fluid extraction is desired, the valve is opened and fluid flows from the body area to a fluid port where the fluid may be collected.Type: GrantFiled: July 3, 1996Date of Patent: August 10, 1999Inventor: Paul A. Williams

Patent number: 5935116Abstract: A garment (1) is disclosed for fixing a urine bag (2) on the leg (3) of a user. The garment includes a tubular part (6) having elastic bands (9, 10) at its ends, said bands fitting tightly around the leg (3) of the user. The tubular part is provided with an integrally formed pocket (11), the tubular part being formed by a dual layer knitted structure except in the area of the pocket (11). At the pocket bottom (13) there is an opening (14) for the discharge pipe (15) of the urine bag. The garment (1) is manufactured easily in endless webs, which are separated, and subsequently the two end edges (31, 32) are knitted together (33) in order to form the tubular shape. The garment provides safe fixing of the urine bag (2) as the latter will be supported inside the pocket (11) and be held against the leg of the user due to the elastic bands (9, 10), which are dimensioned so as to be able to carry a full urine bag.Type: GrantFiled: September 5, 1997Date of Patent: August 10, 1999Assignee: Tytex A/SInventor: Johannes Nyvang Kristensen

Patent number: 5916203Abstract: A method of making a composite material having elasticized portions includes supplying a web of temperature sensitive elastic material, applying a microwave sensitive material to selected regions of the elastic material and subsecting the composite material to microwave energy. The microwave energy may be converted into heat by the microwave sensitive material thereby heating the microwave sensitive material and activating regions of the temperature sensitive elastic material adjacent the microwave sensitive material. The activated regions of the elastic material provide the elasticized portions in the composite material. Alternatively, the microwave sensitive material may reflect the microwave energy which may then directly heat and activate the regions of the elastic material opposite the selected regions to which the microwave sensitive material is applied. The method is particularly useful in the manufacture of garment-type articles such as disposable absorbent articles.Type: GrantFiled: November 3, 1997Date of Patent: June 29, 1999Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Robert Griffiths Brandon, Franklin Mean-Chi Chen, Robert Eugene Vogt

Patent number: 5911698Abstract: A method for the removal of cholesterol, triglycerides and other lipids from animal plasma, serum or other suitable blood fractions, as a discontinuous flow system, the method comprising withdrawing blood from a subject, separating the required fraction from the blood and mixing with a solvent mixture which extracts the lipids from the fraction, after which the delipidated fraction is recombined with the blood cells and returned to the subject, wherein the solvent extraction step is carried out separately and remote from the subject. The delipidated fraction is washed with a second solvent before being recombined with the blood cells. To ensure that the delipidated fraction is free from all extraction solvent, the fraction is mixed with an absorbent specific for the solvent that is being removed. The preferred absorbent is a macroporous polymeric bead contained in the pores of a sintered glass or plastic sphere, the being capable of absorbing organic molecules from an aqueous solution.Type: GrantFiled: June 10, 1997Date of Patent: June 15, 1999Assignee: Aruba International Pty.
