Abstract
Abstract A two-piece adapter for rotatably connecting two fluid transport members, the adapter including a stem for one of the members, and a connector (which may be for example a Luer connector) for the other member. The connector has a collar which is wrapped around the flange to capture the stem. The collar is deformed to wrap around the flange after the flange and the collar are joined. Preferably the adapter is made of plastic, transparent material.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
A two-piece adapter for rotatably connecting a first member to a second member, comprising: (a) a first member including a plastic cylindrical flange having a flange inner diameter and a flange outer diameter and having a first flange end and a second flange end, the second flange end defining a shoulder; and (b) a plastic second member having an annular cavity defined by inner and outer surfaces complementary in shape to the cylindrical flange and said outer surface being further complementary in size to said cylindrical flange, the cavity having a first surface end, the inner and outer surfaces and the first surface end receiving the first flange end in a nesting relationship so as to laterally stabilize the flange, and the cavity having a second end extending from the outer surface past said shoulder, said second end being deformed over the flange to form a capture ring after nesting of the flange to engage the shoulder to rotatably connect the first and second members.
Claim 2
Dependent Claim
165 words
A two-piece adapter for rotatably connecting a first member to a second member, comprising: (a) a first member including a plastic cylindrical flange having a flange inner diameter and a flange outer diameter and having a first flange end and a second flange end, the second flange end defining a shoulder; and (b) a plastic second member having an annular cavity defined by inner and outer surfaces complementary in shape to the cylindrical flange and said outer surface being further complementary in size to said cylindrical flange, the cavity having a first surface end, the inner and outer surfaces and the first surface end receiving the first flange end in a nesting relationship so as to laterally stabilize the flange, and the cavity having a second end extending from the outer surface past said shoulder, said second end being deformed over the flange to form a capture ring after nesting of the flange to engage the shoulder to rotatably connect the first and second members.
Claim 3
Dependent Claim
13 words
The adapter of claim 1 wherein the second member includes a Luer connector.
Claim 4
Dependent Claim
21 words
The adapter of claim 1 further comprising an O-ring disposed on the second member to seal the first and second members.
Claim 5
Dependent Claim
18 words
The adapter of claim 1 wherein the first and second members are made of a rigid engineering resin.
Claim 6
Dependent Claim
16 words
The adapter of claim 1 wherein the first and second members are made of a polycarbonate.
Claim 7
Dependent Claim
146 words
An assembly for a two-piece adapter for rotatably connecting a first member to a second member, comprising: (a) a first member including a plastic cylindrical flange having a first flange end and a second flange end, the second flange end defining a shoulder; and (b) a plastic second member having an annular cavity defined by inner and outer surfaces complementary in shape to the cylindrical flange and said outer surface being further complementary in size to said cylindrical flange, the cavity having a first surface end, the inner and outer surfaces and the first surface end receiving the first flange end in a nesting relationship so as to laterally stabilize the flange and the cavity having a second end extending therefrom, the second end being deformable over the flange after nesting of the flange to engage the shoulder to rotatably capture the first and second members.
Claim 8
Dependent Claim
146 words
An assembly for a two-piece adapter for rotatably connecting a first member to a second member, comprising: (a) a first member including a plastic cylindrical flange having a first flange end and a second flange end, the second flange end defining a shoulder; and (b) a plastic second member having an annular cavity defined by inner and outer surfaces complementary in shape to the cylindrical flange and said outer surface being further complementary in size to said cylindrical flange, the cavity having a first surface end, the inner and outer surfaces and the first surface end receiving the first flange end in a nesting relationship so as to laterally stabilize the flange and the cavity having a second end extending therefrom, the second end being deformable over the flange after nesting of the flange to engage the shoulder to rotatably capture the first and second members.
Claim 9
Dependent Claim
13 words
The assembly of claim 6 wherein the second member includes a Luer connector.
Claim 10
Dependent Claim
21 words
The assembly of claim 6 further comprising an O-ring disposed on the second member to seal the first and second members.
Claim 11
Dependent Claim
18 words
