Abstract
Abstract A connector for an ambulatory dialysis system which effectively prevents peritoneal infections such as peritonitis. The connector is comprised of a cylinder containing a disinfecting solution which continuously bathes the male and female connectors of a tube during use. A highly absorbent material is packed in the cylinder and saturated with a disinfectant and bathes the male and female connectors when connection is made and continually bathes them during use. A connection is provided by a male fitting on the end of a tube connected to a bag of dialysate fluid or an abdominal opposing tube. Male connector is inserted into the female connector through the cylinder containing the absorbent material saturated with the disinfectant. The absorbent material is packed such that the male connector contacts the absorbent material during insertion to disinfect the opposing ends simultaneously while connection is being made.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
94 words
A peritoneal dialysis fluid connecting device comprising; enclosure means; an absorbent packing material in said enclosure means; said absorbent packing material being substantially saturated with a disinfectant solution; a first tube connecting end for supplying a peritoneal dialysis fluid; a second tube connecting end adapted to telescopically mate with and connect to said first tube connecting end; means allowing said first and second tube connecting ends to be telescopically mated inside said enclosure means so that the connecting ends are bathed in said disinfectant solution when the connection is being made and throughout use.
Claim 2
Dependent Claim
94 words
A peritoneal dialysis fluid connecting device comprising; enclosure means; an absorbent packing material in said enclosure means; said absorbent packing material being substantially saturated with a disinfectant solution; a first tube connecting end for supplying a peritoneal dialysis fluid; a second tube connecting end adapted to telescopically mate with and connect to said first tube connecting end; means allowing said first and second tube connecting ends to be telescopically mated inside said enclosure means so that the connecting ends are bathed in said disinfectant solution when the connection is being made and throughout use.
Claim 3
Dependent Claim
51 words
The device according to claim 1 in which said retaining means comprises; a ring attached to the open end of said cylinder; a recess in said ring; a shoulder on the shank of said plug; a ridge on said shoulder adapted to engage and lock into the recess in said ring.
Claim 4
Dependent Claim
60 words
The device according to claim 2 in which said sealing means for sealing said cylinder comprises: a second open-ended cylinder on said plug having an internal diameter approximately equal to the outside diameter of the first open-ended cylinder; said second open-ended cylinder adapted to slide over and seal the first cylinder when said plug shank engages said connecting tube end.
Claim 5
Dependent Claim
36 words
The connecting device according to claim 1 in which said means for allowing said first and second tube connecting ends to be telescopically mated inside said enclosure means comprises a passageway passing through said enclosure means.
Claim 6
Dependent Claim
22 words
The connecting device according to claim 4 in which said enclosure means is separate from said first and second tube connecting ends.
Claim 7
Dependent Claim
40 words
The connecting device according to claim 5 in which said enclosure means is a hollow cylindrical means having openings at each end in communication with a passageway through said absorbent packing material for receiving said first and second connecting ends.
Claim 8
Dependent Claim
23 words
The connecting device according to claim 4 in which said enclosure means is formed around and attached to one of said connecting ends.
Claim 9
Dependent Claim
40 words
The connecting device according to claim 7 in which said enclosure means is a hollow cylindrical means having openings at each end in communication with a passageway through said absorbent packing material for receiving said first and second connecting ends.
Claim 10
Dependent Claim
43 words
The connecting device according to claim 6 in which said enclosure means comprises a pair of enclosures formed on the ends of each of said first and second tube connecting means constructed to mate when said first and second tube connecting ends mate.
Claim 11
Dependent Claim
46 words
The connecting device according to claim 9 in which said pair of enclosures extend beyond the respective ends of said first and second tube connecting ends to shield said tube connecting ends from contamination whereby said pair of enclosures mate before said tube connecting ends mate.
Claim 12
Dependent Claim
62 words
The connecting device according to claim 6 in which said passageway is formed in said absorbent packing material to be smaller than the diameter of said first and second tube connecting ends so that said first and second tube connecting ends make contact with and displace said absorbent material and are bathed in said disinfectant solution when said connection is being made.
Claim 13
Dependent Claim
20 words
The connecting device according to claim 11 including sealing means for sealing said openings to said passageway to exclude contaminants.
Claim 14
Dependent Claim
29 words
The connecting device according to claim 12 in which said sealing means includes removal means constructed and arranged to allow removal without contaminating the interior of said enclosure means.
Claim 15
Dependent Claim
44 words
The connecting device according to claim 13 in which said sealing means comprises a disposable plug means inserted in said passageway; said plug means including means covering and sealing the open ends of said enclosure means; and retaining said plug in said enclosure means.
