Dialysis Box with Backflow Preventer, Trap Primer, and Thermostatic Mixing Valve

US PATENT 9724457
More Information

The dialysis process is performed by medical care providers.  In most all cases the health care specialist utilizes a dialysis machine that typically demands cold, potable water and waste water connection. Typically, a dialysis service cabinet requires one service box with a hose bib and drain connection, as well as, an additional access box for the backflow preventer and trap primer.  Incorporating an all inclusive dialysis box into the design has multiple advantages.

The all-in-One Dialysis Box System eliminates the need for excess dedicated cold water distribution piping, by concealing both a backflow prevention device and a trap primer inside of the access box.  This eliminates the cost and space requirements for additional wall space intended for remote backflow preventers, trap primers and for supplementary access doors. The benefits of utilizing the all-in-One Dialysis Box System are that it consolidates all the required components into one user friendly, esthetically pleasing and completely functional cabinet. Most importantly, it increases patients’ safety by protecting the water source at the point of connection.
