Patent number: 5359791Abstract: A therapeutic arch support is described, more particularly intended for therapy of disorders of the circulation of the foot, for the treatment of venous insufficiency within the area of the leg or for bedding load-sensitive feet, especially for bedding the feet of diabetics suffering from foot detects. The arch support has a multi-layer construction with a highly resilient elastomer core layer standardized so as to be as soft as possible and a thin, top-side covering layer in the form of a smooth fibrous structure. On the side of the sole, a separate supporting layer of flexible, machinable and compression-resistant material may be provided.Type: GrantFiled: July 15, 1993Date of Patent: November 1, 1994Assignee: IPOS GmbH & Co. KGInventors: Jan Prahl, Jean P. Comtesse

Patent number: 4426742Abstract: Breast prosthesis of an elastic plastic, in particular of silicone rubber composition, having a breast molding corresponding to the female breast and having a contact area adapted to the human body form, which carries an adhesive composition for attachment of the breast prosthesis to the body, which is characterized in that the breast molding comprises on the body-contact side, approximately centered, a recess and an adapter type molding retained therein and rotatable about its vertical median axis, the external wall area of which, turned toward the body, is provided with a coating of an adhesive composition tolerated by the skin. Optionally the breast molding comprises in its upper region a soft core which is highly flexible relative to the cup material.Type: GrantFiled: December 1, 1981Date of Patent: January 24, 1984Assignee: Beiersdorf AktiengesellschaftInventor: Jan Prahl

Patent number: 4327727Abstract: The invention relates to a collecting bag for artificial intestinal outlets. It ensures an optimum stoma provision and has an adhesive surface integrated into the collecting bag surface. Thus, a high adhesive strength is obtained when the collecting bag is in use and as a result absolute security is given to the wearer or carrier of the bag, even when vigorous movements are performed.Type: GrantFiled: July 17, 1980Date of Patent: May 4, 1982Assignee: Ipos Gesellschaft fur integriert Prothesen-Entwicklung und orthopadietechnischen Service GmbH & Co., KGInventors: Jan Prahl, Franz Gelbenegger

Patent number: 3991424Abstract: A tubular compression sheath formed of a resilient yarn or fabric is structured to comprise a band defining an upper open end and an oppositely disposed enclosed end with an intermediate portion extending therebetween. The intermediate portion is formed in two sections, with the lower of said two intermediate sections having a knitted pattern with a higher yarn density than the upper intermediate section. The diameter of the sheath progressively decreases from the upper open end toward the lower enclosed end and the intermediate section is preferably formed from yarn having a thickness within a range between about 30 to 44 dtex. The preferred material from which the intermediate section is formed is Nylon 66 HE crimped. The sheath provides a desired radial compression about the limb upon which it is worn without producing undesired axial frictional forces across the area of the intermediate section.Type: GrantFiled: June 9, 1975Date of Patent: November 16, 1976Assignee: Ipos Gesellschaft fur Integrierte Prothesenentwicklung und Orthopadietechnischen Service m.b.H. & Co.
