Abstract: The present invention concerns a pump that includes a drain path for a liquid and a drain unit configured to realize the suction of the liquid along the path. In accordance with the invention, the pump further comprises a containment chamber to contain the drained liquid, and one or more than one exiting conduits in fluid communication with the containment chamber. Moreover, one or more than one vertical conduits are provided that develop from the containment chamber upwards and in fluid communication with the containment chamber. In such a manner, the vertical conduits form with the exiting conduits, through the containment chamber, one or more than one vessels communicating one with the other in such a way that the liquid that is drained by the drain unit into the containment chamber re-ascends along the exiting conduits towards the level of liquid contained in the vertical conduits.

Abstract: The present invention relates to a self-contained unit which employs a manually operable platform/seat attached to a u-channel rail system for the purposes of personal hygiene. The unit mounts to the wall of a shower or bath stall. The system is designed to aid those individuals in need of a secure and stable sitting platform that is vertically adjustable to accommodate the individual user's height. This unit facilitates bathing, showering and other personal hygiene requirements. The unit contains 2 swivel armrests that provide the user stability when moving in and out of the chair and an overhead retractable cage for added security for those individuals requiring additional support. I have found that the advantages of such a devise can reduce bath area accidents caused by slipping and instability and enables those individuals who are physically challenged the freedom to shower independently in a secure environment. There are no known devises of this nature.
