Abstract
Abstract Device for easily and simply coupling to the free end of a small tube (7) mounted on a transfusion needle an apparatus of the type used for coupling a syringe to a drug holding bottle. The device comprises a hollow shaped body (1) that can be coupled to the small tube (7). An axial passageway (13) in the body (1) is closed by a plug (5). A collar (2) shaped as the mouth of a conventional drug bottle projects from the body (1). The collar (2) extends axially and a continuous annular recess (3) is formed therein. The recess (3) has a profile and arrangment sized and shaped to allow for the teeth projecting from the resilient lugs of the apparatus to which the device is to be coupled to be inserted and locked therein.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
242 words
A device for coupling a tube to an apparatus for coupling a syringe to a drug holding bottle, said device comprising: (a) a body having a first end, a second end, a longitudinal axis, and an axial passageway extending from said first end of said body to said second end of said body, said first end of said body being adapted to be connected to a hollow tube such that said axial passageway is in fluid communication with the interior of said hollow tube, said body comprising a first at least substantially cylindrical wall at said second end of said body that is concentric to said longitudinal axis and that has an external annular recess therein spaced from said second end of said body, and (b) a resilient plug mounted on said second end of said body so as to close said axial passageway; (c) said second end of said body comprising: (i) said first at least substantially cylindrical wall; (ii) a first blind recess that is within said first cylindrical wall, that is concentric to said longitudinal axis, and that is open to said second end of said body; and (iii) a lug the radially outer surface of which defines one side of said blind first recess, which is concentric to said longitudinal axis, and which contains said axial passageway, the radially outer surface of said lug which defines one side of said first blind recess being at least substantially cylindrical.
Claim 2
Independent Claim
242 words
A device for coupling a tube to an apparatus for coupling a syringe to a drug holding bottle, said device comprising: (a) a body having a first end, a second end, a longitudinal axis, and an axial passageway extending from said first end of said body to said second end of said body, said first end of said body being adapted to be connected to a hollow tube such that said axial passageway is in fluid communication with the interior of said hollow tube, said body comprising a first at least substantially cylindrical wall at said second end of said body that is concentric to said longitudinal axis and that has an external annular recess therein spaced from said second end of said body, and (b) a resilient plug mounted on said second end of said body so as to close said axial passageway; (c) said second end of said body comprising: (i) said first at least substantially cylindrical wall; (ii) a first blind recess that is within said first cylindrical wall, that is concentric to said longitudinal axis, and that is open to said second end of said body; and (iii) a lug the radially outer surface of which defines one side of said blind first recess, which is concentric to said longitudinal axis, and which contains said axial passageway, the radially outer surface of said lug which defines one side of said first blind recess being at least substantially cylindrical.
Claim 3
Dependent Claim
114 words
A device as recited in claim 1 wherein said first end of said body comprises: (a) a second at least substantially cylindrical wall concentric to said longitudinal axis; (b) a second blind recess that is within said second at least substantially cylindrical wall, that is concentric to said longitudinal axis, and that is open to said first end of said body; and (c) said lug, the radially outer surface of which defines one side of said second blind recess, which is concentric to said longitudinal axis, which extends axially beyond said second at least substantially cylindrical wall, which contains said axial passageway, and which decreases in diameter towards said first end of said body.
Claim 4
Dependent Claim
19 words
A device as recited in claim 2 wherein the radially inner surface of said second blind recess is threaded.
Claim 5
Dependent Claim
29 words
A device as recited in claim 2 wherein the radially outer surface of said lug which defines one side of said second blind recess is at least substantially conical.
Claim 6
Dependent Claim
38 words
A device as recited in claim 1 and further comprising a rigid disk: (a) mounted on said first at least substantially cylindrical wall and said lug; (b) mounting said resilient plug; and (c) closing said first blind recess.
