System for performing peritoneal dialysis
First Claim
1. A system for performing fluid administration on a patient comprising:
- a partial peristaltic pump (1),a liquid distribution system (2) that is a cartridge and that is separate from said pump and that is connected to said pump (1) in such a way that liquid can flow from the liquid distribution system (2) to the pump (1) and vice versa,liquid supply means (3) for supplying liquid to a patient (4) via said liquid distribution system (2) and said pump (1),a patient conduit (5) adapted for connecting said liquid distribution system (2) to a patient (4),wherein said liquid distribution system (2) comprises two distinct hub chambers (7,8) which are separated by a space, the first hub chamber (7) including at least one liquid supply port with dedicated valve means (9), one patient port with dedicated valve means (10) and one pump inlet (26), the second hub chamber (8) including at least one patient port (18) or warmer port (16) with dedicated valve means and one pump outlet (27), said system further comprising control means arranged to close said patient port (10) of the first hub chamber (7) when said liquid supply port (9) is open and vice versa andwherein all ports of the liquid distribution system that communicate with the pump are unidirectional such that liquid only flows in one direction.

Abstract
The invention concerns a system and a method of use of said system for performing fluid administration on a patient, the system comprising a liquid pump, a liquid distribution system, a liquid supply means, and patient conduit. The liquid distribution system comprises two distinct hub chambers. The first hub chamber includes at least one liquid supply port with a dedicated valve means, one patient port with dedicated valve means, and one pump inlet. The second hub chamber includes at least one patient port or warmer port with dedicated valve means and one pump outlet. The system further comprises control means arranged to close the patient port of the first hub chamber when the liquid supply port is open, and vice versa.
