ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an oral cavity cleaning device particularly for bedridden patients.
A currently strongly felt problem is cleaning the oral cavity of people who are necessarily bedridden and in any case cannot keep their head upright.
In such conditions there are considerable problems in emptying the oral cavity of the cleaning liquid and of the dirt particles.
In order to solve this problem, an oral cavity cleaning brush has already been introduced which is substantially constituted by a grip element which has bristles at one end and is internally provided with a through channel which ends at the bristles and is connected to a suction assembly which is connected to the other end of the grip.
This solution has proved to be valid in certain regards but it has the drawback that it is very troublesome to use, since it is necessary to introduce the cleaning liquid in the oral cavity using the other hand or perform the two operations at separate times.
Moreover, with this type of application it becomes troublesome to adjust the amount of liquid introduced in the oral cavity, with severe problems especially in the case of non-autonomous patients.
SUMMARY OF THE INVENTION
The aim of the present invention is to eliminate the above drawbacks, by providing an oral cavity cleaning device, particularly for bedridden patients, which allows to use just one hand to perform all the operations required for hygiene of the oral cavity of people who are not autonomous or are in any case unable to keep their head upright.
Within the scope of this aim, a particular object of the invention is to provide a device in which it is possible to introduce the cleaning liquid in the work area of the brush, being perfectly aware at all times of the amount of liquid administered.
Another object of the present invention is to provide an oral cavity cleaning device, particularly for bedridden patients, which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
Still another object of the present invention is to provide an oral cavity cleaning device, particularly for bedridden patients, which can be easily obtained starting from commonly commercially available elements and materials and is furthermore competitive from a purely economic point of view.
This aim, these objects and others which will become apparent hereinafter are achieved by an oral cavity cleaning device, particularly for bedridden patients, which comprises a body which has a grip portion connected to a front portion provided with bristles and the like, a channel being provided inside said body, said channel ending, at one end, with an opening at said bristles and, at the other end, with an inlet which can be connected to an air suction unit, characterized in that it comprises, inside said channel, a container of a liquid which can be operated from the outside of said body in order to spray said liquid at said opening.
