Abstract
Abstract An adapter assembly comprising, a syringe having a tip, a catheter, and a connector having a body member, a compressible plug, and a compression member. The body member has a bore to receive the plug, and an opening communicating with the bore. The plug has a channel to receive the catheter through the body member opening into the plug channel. The compression member has a nipple receivable in a proximal end of the body member bore, and a proximal port to receive the syringe tip. The compression member may be releasably attached to the body member in such a manner that the nipple bears against the plug and secures the catheter in the plug channel, while the syringe may be attached to the compression member with the syringe tip received in the compression member port.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
281 words
An adapter assembly, comprising: a syringe having a tip; a catheter; and a connector comprising, a body member having an elongated bore and an opening adjacent a distal end portion of the body member communicating with said bore, an elongated plug of elastic material received in said bore in a relatively uncompressed condition of the plug, said plug having a channel extending through the plug with a distal portion of the channel being aligned with the body member opening and with the internal dimensions of at least a distal portion of the channel being slightly larger than the outer dimensions of said catheter to receive the catheter through said body member opening, a compression member having a nipple adjacent a distal end of the compression member and receivable in a proximal end portion of the body member, said compression member having a port adjacent a proximal end portion of the compression member to receive the syringe tip, and a passageway communicating between the port and the distal end of said nipple, with a distal portion of said passageway being aligned with the plug channel when the nipple is received in the body member bore, and means for releasably attaching the compression member to the body member with said nipple received in said bore, and for controlling the distance said nipple projects into said bore such that the nipple compresses said plug in the bore and releasably secures the catheter in said plug channel, said compression member including a distal gripping element defining a space intermediate the gripping element and said nipple to receive the proximal end portion of the body member when the nipple is received in the body member bore.
Claim 2
Dependent Claim
281 words
An adapter assembly, comprising: a syringe having a tip; a catheter; and a connector comprising, a body member having an elongated bore and an opening adjacent a distal end portion of the body member communicating with said bore, an elongated plug of elastic material received in said bore in a relatively uncompressed condition of the plug, said plug having a channel extending through the plug with a distal portion of the channel being aligned with the body member opening and with the internal dimensions of at least a distal portion of the channel being slightly larger than the outer dimensions of said catheter to receive the catheter through said body member opening, a compression member having a nipple adjacent a distal end of the compression member and receivable in a proximal end portion of the body member, said compression member having a port adjacent a proximal end portion of the compression member to receive the syringe tip, and a passageway communicating between the port and the distal end of said nipple, with a distal portion of said passageway being aligned with the plug channel when the nipple is received in the body member bore, and means for releasably attaching the compression member to the body member with said nipple received in said bore, and for controlling the distance said nipple projects into said bore such that the nipple compresses said plug in the bore and releasably secures the catheter in said plug channel, said compression member including a distal gripping element defining a space intermediate the gripping element and said nipple to receive the proximal end portion of the body member when the nipple is received in the body member bore.
Claim 3
Dependent Claim
35 words
The assembly of claim 1 wherein the attaching and controlling means comprises cooperating threads on the inner surface of the body member proximal end portion and on the outer surface of said compression member nipple.
Claim 4
Dependent Claim
44 words
The assembly of claim 1 wherein said compression member includes a distal gripping element defining a space intermediate the gripping element and said nipple to receive the proximal end portion of the body member when the nipple is received in the body member bore.
Claim 5
Dependent Claim
55 words
The assembly of claim 1 wherein said gripping element extends circumferentially around said nipple and defines an annular cavity to receive the proximal end portion of said body member, and in which the compression member includes a flange connecting the gripping element to the compression member intermediate proximal and distal ends of the compression element.
Claim 6
Dependent Claim
24 words
The assembly of claim 1 wherein the body member includes a pair of opposed outwardly directed wings to facilitate manipulation of the body member.
Claim 7
Dependent Claim
24 words
The assembly of claim 1 including means for releasably attaching the syringe to said compression member with the syringe tip received in said port.
Claim 8
Dependent Claim
33 words
The assembly of claim 1 wherein said body member opening and a distal end portion of the plug channel define a distal taper to facilitate placement of the catheter in the plug channel.
