The present invention provides automated peritoneal dialysis systems, methods of operating the systems and devices for performing same. A typical therapy performed by the present invention begins by draining dialysis solution that is already in the patient's peritoneal cavity. The system pumps fresh dialysate from one of a plurality of supply bags, through an in-line heater to the patient's peritoneal cavity. After a dwell period, the spent dialysate in the cavity is pumped out of the patient to a drain or other disposal means. The system then pumps fresh dialysate from the supply bags to the patient and the procedure is repeated as defined in the therapy protocol. The system can pump a last bag of dialysate to the peritoneal cavity for an extended dwell, such as a daytime dwell.

A system and method for automatically adjusting a Continuous Cycling Peritoneal Dialysis (“CCPD”) therapy to minimize the potential for excess intra-peritoneal volume. The adjustments are made at the end of the drain, just prior to the next fill. The adjustments short the next fill, if necessary, to limit the intra-peritoneal volume, add a cycle, if necessary, to use all of the available dialysis solution and will average the remaining dwell time to maximize the therapeutic benefit of the therapy in the allotted time. In another embodiment, a tidal therapy using trended patient UF data is provided.

A pneumatic-snake like appratus and method for routine clearing of clogged plumbing-drain lines in buildings and marine installations, employing an air-supply of 80-120 psi at a nozzle-generated velocity sufficient to virtually disintegrate obstructions logged within the plumbing-drain system. Owing to direct-impact infusion of high-velocity air exiting the special ball-shaped fracturing-nozzle positioned at leading-end of the snaking air-hose, the “Pwr/Clogbuster™” is more effective at breaking-up plumbing-line clump-obstructions than conventional mechanical coiled-metal snake devices. Passed-into a drain-line to point of obstruction, the pneumatic-snake operator opens a control-valve positioned between the air-hose and air-supply unit (a conventional portable air-compressor/reservoir rig);—whereupon a few thrusting blasts at point-blank are sufficient to clear an obstruction. An annular drain-cup device is slip-fitted on the air-hose, and held near the drain-entry point, as to provide splash-deflection protection during the procedure;—plus, generic-variant nozzle configurations are also set forth.

The present teachings describe one embodiment of an anti-splash guard and deodorant pouch adapted for a lavatory device having an interior region for receiving waste fluid. The anti-splash guard may include a fibrous material configured to be positioned in the interior region of the lavatory device so that splash back of fluids contacting the anti-splash guard is reduced. The deodorant pouch advantageously comprises a deodorant material sandwiched between layers of anti-splash material, such as the fibrous material that is used in the anti-splash guard. The deodorant pouch may increased a useful lifespan of the deodorant material held therein by preventing pieces of the deodorant material from falling down the drain of the lavatory device and by reducing the amount of fluid that contacts the deodorant material.

An overflow system in the bathtub has an overflow port and has a drain pipe in connection with the overflow port. A threaded flange has a stub shoulder on one end which is fitted into a circular sleeve on the overflow port. The threaded flange has exterior threads on its outer surface and a thin diaphragm secured to the end thereof opposite to the stub shoulder. A large sealing washer embraces the outside of the circular flange on the overflow port and extends partially over the threads of the threaded flange. A large internally threaded nut is threadably mounted on the outer end of the threaded flange and compresses the sealing washer against a vertical flange on the port to seal the connection between the threaded flange and the port. A decorative cap is frictionally snapped into engagement with protrusions on the outer surface of the nut. The cap can be removed when needed to permit the plumber to gain access to the diaphragm to cut it open for fluid flow after the system has been tested for leaks, or put in place after the cut takes place.

A clog free drain for a surface water drain such as that utilized in a tub or stall shower including a basket having side openings permitting waste water to flow there through and into the drain pipe in which the basket is disposed. Directing waste water into the basket is by a sleeve located coaxially of the basket and the drain pipe and below the drain plate whereby the waste water flows through the sleeve, out an opening in the bottom thereof in to the closed bottom of the basket. The waste water accumulates below and into the sleeve and into the basket to a level of the side openings in the basket where it flows into the drain pipe. Pooling of the waste water in the bottom of the basket allows the debris, hair, soap scum and other suspended particles to accumulate in the bottom of the basket and thus separated from the waste water flowing in to the drain pipe.
