Patent number: 4583976Abstract: A catheter support comprising an anchoring pad and a flexible strap, a portion of which is attached thereto, is disclosed. One side of the anchoring pad carries an adhesive compatible for use with human skin. One side of the strap carries a fastener material. With the pad in place, a catheter is laid against the pad, and the free end of the strap is folded across the catheter. The fastener material of the free end is pressed against the fastener material attached to the pad to hold the catheter in place. Alternatively, the side of the pad opposite the side with the adhesive carries fastener material, and the flexible strap is separate therefrom. A channel is present through the fastener material on either the pad, flexible strap or both to receive the catheter.Type: GrantFiled: May 31, 1984Date of Patent: April 22, 1986Assignee: E. R. Squibb & Sons, Inc.Inventor: Keith T. Ferguson

Patent number: 4559048Abstract: A coupling for joining a pad or dressing to an ostomy bag includes coupling elements each of closed loop form, usually circular to define a stoma aperture therein, the body side element being constructed so that it can be fixed to the pad or dressing and the bag side element being constructed so that it can be fixed to one wall of an ostomy bag. The body side element includes an inner wall which continuously encircles the aperture and a series of projecting members uniformly radially spaced from the inner wall and located in an array which surrounds the inner wall. The bag side element includes a rib member encircling the aperture for making sealing engagement, when the coupling elements are joined, with the outer surface of the inner wall. The coupling also has an annual ring which is constructed to be snap-fitted to the body side coupling element to extend radially outwardly therefrom.Type: GrantFiled: June 25, 1984Date of Patent: December 17, 1985Assignee: Craig Medical Products LimitedInventor: Peter L. Steer
