Abstract

Abstract A tube end closure for medicosurgical tube devices having an encircling removal cap that is captive to the closure body is molded as an integral unit from plastic material. The closure is constructed to make fluidtight union with tapered connectors of Luer syringes. A syringe needle penetratable plug may be fixed inside the closure sufficiently below the proximal end tip so contact of the plug will occur only with a syringe needle when fluids are injected or withdrawn via the closure.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 241 words
An endotracheal tube comprising an inflatable balloon cuff, a secondary lumen and an inflation tube joined to the proximal end of the secondary lumen through which the balloon cuff may be inflated via the secondary lumen, a tube end closure fixed to the proximal end of said inflation tube, said end closure comprising a distal end portion, a proximal end portion, a central body portion, a removal cap for said proximal end portion and fastener strip through which said cap is tied to said central body portion, all of said portions and strip being molded of plastic material as an integral unit, said proximal end portion being of larger diameter than said distal end portion, said central body portion being tapered from said proximal end to said distal end, said removal cap comprising a cylinder portion of inside diameter approximately equal to the outside diameter of said proximal end portion, a transverse top and a central plug depending concentrically inside said cylinder portion from said top, said plug having an outside diameter approximately equal to the inside diameter of said proximal end, said plug being shorter in length than said cylinder portion whereby the free end of said plug is recessed within said cylinder portion, and a plug fixed within said tapered central body portion of the end closure made of soft elastomeric material that may be penetrated by a syringe needle and will reseal upon withdrawal of the syringe needle.
