Abstract: A peritoneal dialysis system includes a control unit configured to (i) store a sleep state pattern for the patient, (ii) begin a patient drain followed by a patient fill when at least one sensor indicates that the patient is in a deep sleep state, (iii) extend a dwell period if the sleep state pattern indicates that the patient will enter a subsequent deep sleep state within a first time duration after a programmed dwell period, and (iv) shorten the dwell period if the sleep state pattern indicates that the patient will leave the deep sleep state within a second time duration after an end of the programmed dwell period. The system alternatively or additionally assesses or records a stress level of and/or a fluid/caloric intake by the patient and takes actions accordingly.

Abstract: A trocar for peritoneal dialysis is disclosed herein. An example trocar includes a conduit having two or more parallel lumens and a head connected to a first end of the conduit. The head includes two (or more) parallel lumens that are aligned respectively with the parallel conduit lumens and includes at least one of a gasket or a seal for each lumen. The trocar also includes a coupler connected to the head. The coupler includes two (or more) parallel lumens that are aligned respectively with the parallel lumens of the head. The coupler includes a coupling mechanism for each lumen for securing surgical tools in place after insertion into a patient. The trocar may also include an obturator having a shaft that is removably inserted through the coupler, head, and conduit to protrude from a second end of the conduit.
