BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a new type of movable washstand, more particularly intended for the hospital environment, but nonetheless not limited to this single application.
2. Description of the Prior Art
Certain patients, or even simply elderly people, are often so frail that it is not possible for them to get up to wash or to simply freshen up. Now, hygiene and comfort of these people nevertheless make it necessary for them to freshen up, even if only once a day. In order to do this, it was firstly proposed to use two bowls which would be placed on the board which also served as a support for meal trays. Aside from the impractical aspect of this method it does not, moreover, fulfill the most elementary conditions of hygiene, required for certain pathologies, especially contagious ones. Moreover, the minimum comfort conditions are not met.
Movable washstands were then proposed, for example washstands on castors, comprising a sink communicating via an evacuation pipe with a waste-water storage tank. The water necessary for washing or for freshening up is generally contained in a basin or a bowl simply placed on the washstand. Once again, the conditions of hygiene, although better respected than in the preceding case, still remain insufficient for a great number of applications. Moreover, the patient is obliged to bend to one side or the other of his bed in order to be able to reach the washstand, and thus to freshen up. Finally, this type of movable washstand requires a lot of manipulation for the nursing staff and thus proves to be impractical.
SUMMARY OF THE INVENTION
The invention aims to overcome all these various drawbacks. It proposes a movable washstand, especially intended for the hospital field or people hospitalized at home, intended to allow a bed-ridden person to freshen up under hygienic and comfortable conditions compatible with the conditions required especially in the hospital environment.
This movable washstand comprises: of one of its ends a hollow trough and a tap associated with this trough, storage tank.
This movable washstand is characterized in that the upper tray is articulated on the trolley about a vertical axis situated in the vicinity of the end of the tray opposite the trough.
In other words, the invention consists in providing a movable washstand with an upper tray which can move rotationally in a horizontal plane, in order to allow the trough to be placed facing the bed-ridden patient, regardless of where the washstand is placed at the side of the bed. This facility, which allows the comfort of the patient to be considerably enhanced runs into a certain number of technical difficulties which are resolved by the movable washstand in accordance with the invention.
Advantageously, in practice: articulation turntable, in the shape of a ring comprising a ball bearing, coaxial with the vertical articulation axis, and fixed on the upper face of the trolley, at the interface of the upper tray and of the trolley, to allow a 360 degrees rotation of the tray; cells which are rechargeable, pumping from the water reserve and supplying an annular duct defined by two circular half-rings respectively a lower one and an upper one, situated coaxially with the articulation axis of the upper tray on the trolley, and situated in a plane slightly lower than the articulation turntable, the upper half-ring being connected by at least one pipe to the tap, and the lower half-ring being connected by at least a pipe to the pump; polytetrafluoroethylene, and sealing of the annular duct is provided by two concentric neoprene annular seals, situated in grooves made for this purpose on the facing faces of said half-rings; center of the tray, and the trough is closed off by a bung, the former communicating with an evacuation pipe for waste water ending in the waste-water storage tank situated under the half-rings defining the annular duct, after passing through the center of said duct; axis of revolution of said tank, and having at its center a protuber
