Abstract
A catheter assembly for draining and collecting fluid from a body cavity has a container having an inner containment space defined therewith. An elongate tubular catheter extends longitudinally through the container. A tip member/lubricant reservoir is mounted to the catheter passage opening. A quantity of lubricant is disposed within a tip member/lubricant reservoir and lubricate the catheter as it is extended from the container.
Claims9
A catheter assembly for draining and collecting fluid from a body cavity, said assembly comprising:
- a container having an inner containment space defined therewithin, said container having a fluid reservoir portion and a chimney portion which extends from said fluid reservoir portion, said fluid reservoir portion having a first width and said chimney portion having a second width which is less than said first width;
- a catheter passage opening formed in the chimney portion at a first location;
- a tip member/lubricant reservoir mounted to the catheter passage opening, said tip member/lubricant reservoir having:
- i) a hollow bore extending longitudinally therethrough, said hollow bore having an inner surface of a diameter which is larger than the outer diameter of the catheter;
- ii) a first annular rib extending inwardly from the inner surface of the bore of the tip member/lubricant reservoir defining a first lubricant reservoir space distal thereof, said first annular rib having an inner diameter which is smaller than the inner diameter of the hollow bore, but larger than the outer diameter of the catheter, and, a quantity of lubricant being disposed within said first lubricant reservoir space;
- said catheter being initially positioned within the inner containment space of the container such that a portion of the catheter extends through said chimney and into the bore of the tip member/lubricant reservoir, the catheter being thereafter advanceable in a distal direction through the first annular rib such that the distal end of the catheter will become projected out of the tip member/lubricant reservoir and a layer of lubricant will be deposited on the outer surface of the catheter, the thickness of said layer of lubricant being regulated by the inner diameter of the first annular rib.
