Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
123 words
A valve assembly, comprising: a hollow body member having a cavity; a compression member received on one end of the body member and having an annular flange aligned with the cavity; means for adjusting the position of the compression member relative to the body member; a first elastic valve member received in the cavity and having a disc with slit means extending therethrough, and annular rim extending from the disc; and a second elastic valve member received in the cavity and having a disc with slit means extending therethrough, and an annular rim extending from the disc, said first and second valve members sealingly engaging against a catheter passing therethrough, and being responsive to compression by the compression member to immobilize the catheter.
Claim 2
Dependent Claim
123 words
A valve assembly, comprising: a hollow body member having a cavity; a compression member received on one end of the body member and having an annular flange aligned with the cavity; means for adjusting the position of the compression member relative to the body member; a first elastic valve member received in the cavity and having a disc with slit means extending therethrough, and annular rim extending from the disc; and a second elastic valve member received in the cavity and having a disc with slit means extending therethrough, and an annular rim extending from the disc, said first and second valve members sealingly engaging against a catheter passing therethrough, and being responsive to compression by the compression member to immobilize the catheter.
