  • Patent number: 4811847
    Abstract: A package for an urinary catheter consists of a generally rectangular tray with an open top, to which a peel-back cover is bonded, containing a catheter assembly, a syringe prefilled with bacteriostatic water, and two gloves. The catheter assembly is designed such that a urinary catheter may be simply and efficiently placed into the bladder under sterile conditions. The catheter assembly consists of a heat shrunk seal to hold the end cap, three intermediate caps with antiseptic soaked sponge tips bonded to the ends, and the tube-like guide in proximity therewith. The catheter passes through the guide after removal of the heat shrunk seal and the systematic removal and utilization of the end cap and the three intermediate caps. A protective shroud encloses the distal end of the catheter, as it is bonded to the guide. A biocompatible lubricant is contained between the third intermediate cap and the guide.
