Abstract
Abstract A pair of separate conduits, each having an internal seal zone, may be joined by the method which comprises sealingly joining the ends of the conduits together; thereafter adding an antiseptic into the area of the joined conduits between internal seals formed in the zones; and then opening said internal seals without separating the conduits to permit internal fluid flow through the joined conduits.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
In a connector carried on the end of a first conduit for sealingly connecting with another connector carried on another conduit, the improvement comprising: a portion of the first conduit within said connector being defined by a semipermeable wall member, a source of antiseptic which can penetrate through said wall member into the first conduit, means for retaining said source of antiseptic in a region communicating with the side of said wall member opposed to the first conduit, and means for blocking flow through said first conduit to permit the establishment of a sealed zone, including a portion of the first conduit into which the antiseptic can diffuse for antibacterial effect.
Claim 2
Dependent Claim
111 words
In a connector carried on the end of a first conduit for sealingly connecting with another connector carried on another conduit, the improvement comprising: a portion of the first conduit within said connector being defined by a semipermeable wall member, a source of antiseptic which can penetrate through said wall member into the first conduit, means for retaining said source of antiseptic in a region communicating with the side of said wall member opposed to the first conduit, and means for blocking flow through said first conduit to permit the establishment of a sealed zone, including a portion of the first conduit into which the antiseptic can diffuse for antibacterial effect.
Claim 3
Dependent Claim
39 words
The connector of claim 1 in which multiple-way valve means are provided to selectively provide communication between said first conduit and a plurality of other conduits, said multiple-way valve means being capable of temporarily sealing any of said conduits.
Claim 4
Dependent Claim
30 words
The connector of claim 2 in which said semipermeable wall member is carried within said multiple-way valve means for selective rotation for providing communication between their respective conduits as desired.
Claim 5
Dependent Claim
29 words
The connector of claim 3 in which said semipermeable membrane wall carries impermeable strip members on a portion of its surface to selectively control the diffusion of antiseptic therethrough.
Claim 6
Dependent Claim
66 words
In a connector carried on the end of a first conduit, said connector having a solid, inner surface defining an inner space capable of providing communication between said first conduit and another conduit in communication with said connector, the improvement comprising, in combination: means associated with said connector for providing a diffusion of antiseptic through said solid, inner surface into said inner space for antibacterial effect.
Claim 7
Dependent Claim
66 words
In a connector carried on the end of a first conduit, said connector having a solid, inner surface defining an inner space capable of providing communication between said first conduit and another conduit in communication with said connector, the improvement comprising, in combination: means associated with said connector for providing a diffusion of antiseptic through said solid, inner surface into said inner space for antibacterial effect.
Claim 8
Dependent Claim
12 words
The connector of claim 5 in which said antiseptic is chlorine gas.
Claim 9
Dependent Claim
36 words
The connector of claim 5 which carries a source of chlorine releasing material in a position adjacent said inner space, the chlorine released from said chlorine releasing material being capable of diffusion into said inner space.
Claim 10
Dependent Claim
13 words
The connector of claim 7 in which said chlorine releasing material is trichloro-s-triazinetrione.
