Abstract

A flow set for administering peritoneal dialysis solution in automated peritoneal dialysis which comprises interconnecting flow conduits for connecting respectively with (1) a patient'"'"'s catheter, (2) a container for warming dialysis solution, (3) a drain line, and (4) a source of dialysis solution. The flow conduit (4) for connecting with the source of dialysis solution defines at least three branching conduits having connectors on their respective ends for communication with separate containers of dialysis solution. In accordance with this invention, means are provided for causing the flow path resistance through the conduit (4) of the respective flow paths passing through each of said branch conduits to be substantially equal.

Claims

1. An administration set for use in association with a peritoneal dialysis cycler machine having predetermined locations for supporting first, second, and third peritoneal dialysis solution containers, said administration set comprising:

first, second, third, and fourth branch conduits each having essentially the same interior diameter, said first and second branch conduits being essentially equal in length, said third branch conduit being longer than said fourth branch conduit,

a first junction joining an end of said first branch conduit and an end of said second branch conduit in common flow communication with an end of said third branch conduit, the other ends of said first and second branch conduits being individually attachable in flow communication with, respectively, the first and second containers of peritoneal dialysis solution,

a second junction joining the other end of said third branch conduit in flow communication with an end of said fourth branch conduit, the other end of said fourth branch conduit being attachable in flow communication with the third container of peritoneal dialysis solution, and

means defining a bushing located within said fourth branch conduit for restricting fluid flow so that, when the first, second, and third containers are located at their predetermined locations on the cycler machine, the resistance to fluid flow between the third container and said second junction is automatically made essentially equal to the resistance to fluid flow between either the first or second container and said second junction.
