The supply line comprises, in turn, at least one pump and one filter suitable to guarantee the elimination of infective elements that might be present in the water coming from the water distribution network and to guarantee a filtering of the liquid disinfectant that might have been contaminated even after filling the apparatus.

## Background
TECHNICAL FIELD
The present invention relates to a mobile body disinfection apparatus.
In particular the apparatus according to the present invention is an effective means for combating the transmission of infections via contact with contaminated hands in professional activities such as those of physicians, veterinary surgeons, etc.
BACKGROUND ART
The results of international studies have shown that each year the number of hospital infections transmitted via contact with contaminated hands is between 450,000 and 700,000, with an annual death rate of between 4,500 and 7,000. At least 30 percent of these could be prevented by correct and regular disinfection, which could reduce the number of deaths by about 2,000 each year. According to the above study the main cause of the majority of these infections is simply unclean hands. In many of the places where activities are performed, such as surgical dressing rooms and areas of transit in wards and corridors, there are no disinfection facilities that can easily be accessed by healthcare personnel, who should have convenient access to these and be able to disinfect themselves without any particular hindrance to their professional activities.
DISCLOSURE OF INVENTION
The purpose of the present invention is to produce a series of apparatus having technical characteristics such as to guarantee the disinfection of people in medical and healthcare environments regardless of the availability of access to the water and/or electricity distribution system.
The present invention relates to a mobile body disinfection apparatus as claimed in claim 1.

BEST MODE FOR CARRYING OUT THE INVENTION
In FIGS. 1 and 2 designated as a whole by number 1 is the mobile body disinfection apparatus according to the present invention.
The mobile apparatus 1 comprises a carrying structure 2 that is parallelepiped in shape and provided with four wheels 3 attached to a base 2a thereof suitable to render it mobile. A ceramic washbasin 4 is set in an upper portion 2b of the carrying structure 2. An electronic tap 5 is mounted over said washbasin 4 and provided with a photoelectric cell which is not illustrated for the sake of simplicity.
Inside the carrying structure 2, the mobile apparatus 1 comprises a filling tank 6 and a supply line 7 to carry a liquid disinfectant from the tank 6 to the tap 5. Here and in the rest of this document, the term liquid disinfectant means either a mixture of water and a disinfectant product dissolved in the water or water that has been appropriately filtered as described below and which is used for disinfection.
The filling tank 6 may be insulated by means of suitable insulating material to enable the liquid disinfectant to be maintained at the right temperature for the entire working shift. A specific thermostat provides information on the temperature of the liquid.
The supply line 7 comprises an inlet pipe 8 that draws the liquid from the tank 6, a pump 9 connected to the inlet pipe 8 and suitable to guarantee the movement of the liquid disinfectant, a filter 10, a first connecting pipe 11 from the pump 9 to the filter 10 and a second connecting pipe 12 from the filter 10 to the tap 5. In particular, the filter 10 guarantees the elimination of bacteria, cysts, colloidal substances, legionella, etc., which may be present in the water coming from the water distribution network and at the same time guarantees the filtering of the liquid disinfectant that could have been contaminated even after filling the apparatus. The filter 10 used in the embodiment that is illustrated is marketed by EVERPURE S.A. under the name of MicroGuardTM.
The inlet pipe 8 and the connecting pipes 11 and 12 are made of silicone to prevent the proliferation of bacteria.
Inside the carrying structure 2, the mobile apparatus 1 also comprises a waste tank 13 arranged beneath the filling tank 6, a pipe 13a connecting the waste tank 13 with the washbasin 4 and a drainage line 14. The drainage line 14 comprises an inlet pipe 15 that draws liquid from the tank 13, a pump 16 connected to the inlet pipe 15 and a drainage pipe 17.
The waste liquid is filtered through a specific filter 18 arranged on a drain 19 and, moreover, the waste tank can be specifically sanitized by means of processes capable of eliminating viruses and bacteria before being discharged into the sewerage system. Such treatment allows the waste water to be discharged into the sewerage system without bacteria, viruses, etc.
The mobile disinfection apparatus comprises an electric control unit 20, powered by a 12V battery or by a specific 12V power supply unit, which is used to control all the functions of the apparatus and includes luminous LEDs and information that is displayed on a screen 21 and any acoustic signals to interface with the user.
In particular, the control unit 20 is powered by means of a re-chargeable battery 22 and controls: the level of the liquids in the filling tank 6 and in the waste tank 13 by means of two respective level probes 23 and 24; the action of the two pumps 9 and 16, respectively to move the liquid disinfectant and the waste liquid; and the action of the electronic tap 5.
The control unit 20 also controls the charge level of the battery 21; it controls liquid filling by means of a pushbutton; and, optionally, it controls the timed dispensing of the liquid disinfectant through the tap 5, also by means of a pushbutton.
Another function of the control unit 20 is to guarantee safe operation and, thus, to interrupt dispensing when the filling tank 6 is empty, and when the waste tank 13 is full.
It will be clear from the above description that the body disinfection apparatus according to the present invention guarantees efficient disinfection thanks to the liquid disinfectant obtained by adding specific products to the water coming from the water distribution network, and to the thorough and effective filtering process by the filter 10 which thus prevents said water from constituting a potential source of infection.
Moreover, the apparatus is designed in such a way that the user does not come into contact with other sources of infection after the liquid disinfectant has been dispensed. The electronic tap 5 is provided with a photoelectric cell, via which an electric signal is sent to the pump 9, avoiding the need for the user to touch anything so that hand disinfection is performed simply and quickly. Alternatively, dispensing can be timed and controlled by means of a specific pushbutton. Dispensing timer control can be applied to a single tap or hand-held shower.
The use of the hand-held shower offers important advantages both in veterinary surgeries and for cleaning hospital patients who are unable to move. Moreover the liquid disinfectant flow can be adjusted to suit specific needs.
The mobile disinfection apparatus 1 comprises a filling pipe that is not illustrated, which connects the filling tank 6 to the water distribution network to supply water to said tank 6. This is done by pressing a filling button to open a filling valve of a type that is known and is not illustrated. The disinfectant products are introduced into the tank 6 before the water and dissolve in water to form the liquid disinfectant. It will be apparent that the disinfectant products must be chosen according to the specific use and type of activity to be performed.
Once the procedure to fill the tank 6 with water has been started, no other action is required. The control unit 20 controls the closing of the filling valve when the level probe 23 detects that the tank 6 is full.
The emptying procedure consists of placing the drainage pipe 17 in correspondence with a point of access to the sewerage system, such as a toilet or bidet, and sending a drain command via the control unit 20.
FIGS. 3-9 illustrate seven further embodiments of the mobile disinfection apparatus according to the present invention, which respond to specific needs depending on the level of mobility of the users, with no differences with respect to the description of the apparatus 1 as regards the characteristics for filling, dispensing and drainage.
