Abstract:
An in-line site a fluid stream and usable with a blunt cannula device, the site comprising:a housing defining an inlet and an outlet and a fluid flow path channel therethrough and a side channel which communicates with said fluid flow path channel; tubing members connected to said inlet and said outlet; a housing and resilient sealing means forming a seal for an end of said side channel, said housing including a first end defining a tapered interior surface and terminating in an annular member, wherein said tapered interior surface terminates in an annular channel formed by a ridge projecting inwardly from said interior surface, and said resilient sealing means being carried by said housing and including a generally cylindrical sealing member having a first end and a second end and being positioned in said housing first end adjacent said tapered interior surface such that a void is created by said annular channel, said sealing member having a resealable opening therein and being axially compressed around a peripheral edge of its first end by said annular member, wherein said opening opens outwardly such that a blunt cannula can be sealingly inserted through said opening and placed in fluid flow communication with said flow channel and such that the blunt cannula can be removed therefrom with said flexible means interacting with said housing so as to reseal said resealable opening, said tapered interior surface interacting with a side peripheral surface of said sealing member so as to generate resealing radial forces, directed inwardly toward a centerline in said flow channel, to urge said resealable opening into a closed condition, and so as to deform said sealing member side peripheral surface to conform to said tapered interior surface, and wherein said flexible means contacts said ridge during insertion of the blunt cannula through said resealable opening and deforms into said annular channel; and said first end including means, engaged with said peripheral surface, for retaining said sealing means therein.
