Abstract: An animal restraint jacket includes an elongated sheet formed of a fabric which is stretchable in the longitudinal direction. A pair of leg holes are formed in the sheet proximal to and spaced from the opposing ends of the sheet, such that the jacket is fastened along the chest of the animal. An aperture is formed in the sheet midway between the ends, and a pair of elastic straps are attached at their ends adjacent the aperture, to receive and hold a catheter or other medical device extending through the aperture. A flap is attached along one side edge to the sheet and extends to cover the aperture and elastic straps, and any medical device secured under the straps.

Abstract: A catheter includes an inner cannula formed of a soft flexible stretchable biocompatible material and attached to a needle on a hub at the proximal end thereof. The inner cannula is slidably journaled through an outer cannula formed of the same biocompatible material, the inner cannula projecting outwardly out of the distal end of the outer cannula. The outer cannula proximal end is connected to the hub by a tube of heat shrinkable material. Three collars are mounted on the projecting portion of the inner cannula, the distal collar clamped in position to prevent slidable movement of the intermediate and proximal collars off of inner cannula, and the intermediate and proximal collars slidably mounted on the inner cannula.

Abstract: A method of inhibiting adherence of bacteria, fungus and other similar microorganisms to the surface of biomaterials is disclosed wherein biomaterials such as catheters and prosthetic devices are pretreated with a coating of a simple carbohydrate such as a mono- or di-saccharide. Intravascular catheters treated as such are shown to have significant reduction of adherence by S. epidermidis, S. aureus, Candidas and other organisms associated with nosocomial infection.
