Abstract

An apparatus and a system are provided for delivering a peritoneal dialysis solution to a patient. A connector containing a first set of conduit segments and a loader containing a second set of conduit segments are mated together such as with a mating set of tracks and slots so that the two sets of conduit segments form a plurality of conduits that are each sealed from the other conduits. The loader is provided with a device for mating the conduit segments together in sealed relationship such as an eccentrically mounted rotatable cylinder and a platen in contact with the cylinder. The apparatus permits delivery of the dialysis solution to the patient and removal of the solution subsequently from the patient.

Claims

1. Apparatus for connecting in sealed relationship a connector means for passing a plurality of fluids in separate conduits and loader means for passing a plurality of fluids, said loader means being connected to means for delivering a filtered fluid which comprises

said connector means comprising a housing containing a plurality of a first set of conduit segments, said first set of conduit segments having a first set of open ends and a second set of open ends,

said loader means containing a plurality of a second set of conduit segments, said second set of conduit segments having a third set of open ends and a fourth set of open ends,

means to position said second set of open ends adjacent said third set of open ends,

an elastic sealing means positioned between said second set of open ends and said third set of open ends and adapted to maintain fluid communication between said first set of open ends and said fourth set of open ends,

and means to contact a portion of said loader means surrounding said third set of open ends and a portion of said connector means surrounding said second set of open ends against said elastic sealing means under pressure thereby to effect fluid communication between each member of said first set of conduit segments with only one member of said second set of conduit segments.

2. The apparatus of claim 1 wherein said means to position comprises tracks on one of said connector means or of said loader means and slots which mate with said tracks on the other of said connector means or loader means.

3. The apparatus of claim 1 wherein said means to contact comprises an eccentrically mounted rotatable means adapted to move a platen containing said second set of conduit segments when said rotatable means is rotated.

4. The apparatus of any one of claim 1, 2 or 3 wherein individual conduit segments of said first set of conduit segments of said connector means are connected respectively to a first filtered concentrate solution, a second concentrate solution, a dilute peritoneal dialysis solution for delivery to a patient and a drainage conduit for removal of said peritoneal dialysis solution from said patient.

5. The apparatus any one of claims 1, 2 or 3 including means to sanitize water and means to proportion (a) sanitized water, (b) a first filtered concentrate and (c) a second filtered concentrate and wherein said individual conduit segments of said second set of conduits of said loader means are connected respectively to said first filtered concentrate solution from said connector means;

said second filtered concentrate from said connector means;

a dilute sanitary solution containing said first filtered concentrate and said second filtered concentrate from means to sanitize water and means to proportion said (a) sanitized water, (b) said first filtered concentrate and (c) said second filtered concentrate; and

a drainage solution from said connector means.

6. A disposable connector apparatus having a first set of conduit segments for sealing engagement with a second set of conduit segments, one of said first set of conduit segments being connected to a first concentrate solution, a second conduit segment of said first set being connected to a second concentrate solution, a third conduit segment of said first set being connected to a filtered dialysis solution, a fourth conduit segment of said first set being connected to a drainage solution and sealing means to engage said first set of conduit segments to a second set of conduit segments thereby to effect fluid communication between each member of said first set of conduit segments with only one member of said second set of conduit segments.
