Liquid-nebulizing device for the dermatological treatment of the hands
First Claim
1. A liquid-nebulizing device for the dermatological treatment of hands, comprising:
- a rigid housing, said rigid housing including a first portion defining a cavity for the introduction of hands therein;
a second portion, said second portion including a reservoir for a dermatologically acceptable liquid, a spray nozzle adjacent to or extending into said cavity for nebulizing said liquid into said cavity, a pump having separate inlet and outlet ports, a first conduit extending between said inlet port and said reservoir, a second conduit extending between said outlet port and a junction, a third conduit, extending from said junction to said spray nozzle, a fourth conduit extending between said junction and said reservoir, and a solenoid valve positioned along said fourth conduit;
and activating means within said cavity for said pump, comprising a proximity sensor in electrical communication with said pump and said solenoid valve, for detecting the presence of a hand at a predetermined position within said cavity, said activating means, including means for causing said pump to operate while closing said solenoid valve when a hand is present within said cavity, and means for causing said pump to cease operation while opening said solenoid valve when a hand is removed from within said cavity.

Abstract
The invention concerns the technical field of apparata for dispensing liquids over different parts of the human body, either for disinfection or therapeutic purposes, and relates to a liquid-nebulizing device for the dermatological treatment of the hands.
The technical problem to be solved was that of providing a device which could nebulize liquids and readily irrigate in a fully automated manner the entire surface of a skin portion exposed, in particular the hand palms.
The solution to the problem is provided by a device having a housing (2) which comprises a cavity (4a) bound by at least one top roof or cover (6), whereat an infrared light sensor (34) is arranged which responds to the presence of hands located in its direct proximity, and a bottom plate (8) engaging a spray nozzle or atomizer (18) operative to nebulize the liquid to be dispensed in a direction toward said roof (6).
