Description

[0023] The constructive and functional features of the washing device for the ear, nose and throat and the like of the present invention can be better understood from the following detailed description, in which reference is made to the attached drawings which represent a preferred and non-limiting embodiment, in which:

[0024] FIG. 1 schematically illustrates the washing device for treatments for the ear, nose and throat and the like according to a preferred embodiment of the invention;

[0025] FIG. 2 schematically illustrates a block diagram of the functional components of the washing device of the invention.

[0026] With reference to the aforementioned figures, the washing device for treatments for the ear, nose and throat and the like, indicated overall with 10 in the figures, comprises a body 12 defined by a substantially box-like element within which the components functional to the operation of the device are housed, a container element 14 defining a tank for a saline solution, a cannula 16 for use by the individual for the washing operations as better explained in the following and a cable 18 for connecting to the power supply network.

[0027] The body 12 houses a pump 20 which withdraws the saline solution from the container element 14 defining the tank and sends it pressurized to a heat exchanger 22 in which, by means of an electronic probe (not shown in the figures) driven by an electronic control 24, the saline solution is heated to the required temperature with a tolerance of ±1° C.

[0028] The same body 12 externally comprises an on/off switch 26 of the device, a selector 28 for adjusting the temperature of the saline solution and a possible display 30 or, alternatively, LED (Light Emitting Diode) type light indicators with the function of displaying device operation information such as, for example, set temperature value, desired temperature reached, saline solution level in the container element 14 defining the tank and the like.

[0029] According to an alternative embodiment, the selector 28 is of the digital type and is integrated into a touch (or swipe) type display.

[0030] The container element 14 defining a tank has, as previously described, the function of containing the saline solution (at a temperature between 10° and 20° C.) and can be arranged outside the body 12 or integrated therein (in this case the body 12 may comprise a door to allow filling said container element 14 defining the tank).

[0031] The heat exchanger 22 is of a known type (and is therefore not the subject of detailed description herein) and, in the preferred embodiment of the figures, is of the type comprising a stainless steel plate on which a ceramic layer is deposited on which an electrical circuit is printed (made of a high temperature copper alloy—for example copper-beryllium) defining the heating element and above which a layer of glass is melted to define a sealing and electrically insulating surface above which a stainless steel plate provided with a spiral channel is welded within which the saline solution withdrawn from the tank and fed by means of the pump flows, heating.

[0032] Said heat exchanger may also be of the induction heating block type or of the thick-film surface heater type.

[0033] The electronic control 24 receives, by means of the probe, a signal related to the temperature value of the input saline solution entering the exchanger and provides a consent signal for heating said solution up to a temperature value set by the user by means of the selector 28 and keeps the saline solution at the set temperature value (the temperature of the pressurized saline solution transited in the heat exchanger is between 30° and 38° C.).

[0034] The cannula 16 for the individual's use is functional to allow the flow of the pressurized and heated saline solution exiting the heat exchanger 22 into the individual's nasal cavity or nostril.

[0035] For this purpose, said cannula 16 comprises a tube 16′ connected to the body 12 and, in particular, to the heat exchanger 22 and a cap or tip 16″ stabilized to the tube 16′ on the opposite side with respect to that connecting to the body 12, with said cap preferably rounded or “ogival” in shape, functional to an easy introduction into the individual's nasal cavity.

[0036] In an alternative embodiment, the device of the invention may comprise an accessory element defined by a lance or tube having the function of allowing a flow of steam functional to a cleaning of the cannula 16 carrying the saline solution.

[0037] The device of the invention, described above with particular reference to a use for nasal washings, can also be used for ear washings (external ear washing) or eye washings simply by replacing the cannula 16 or the cap or tip 16″ thereof with a cap or tip having a shape suitable for the specific washing operation (ear or eye washing) and may also comprise an additional cannula or tube connected to the cap or tip to allow the exit of the liquid during the washing.

[0038] As it can be seen from the foregoing, the advantages achieved by the washing device for the ear, nose and throat and the like of the present invention are evident.

[0039] The washing device for treatments of the ear, nose and throat and the like advantageously allows washing at favourable temperatures for dissolving mucus and, more in particular, at temperatures between 35° and 38° C., with said temperatures being adjustable by the user with a tolerance of ±1° C.

[0040] A further advantage is that the device of the invention uses a pressurized saline solution which allows an easy and rapid expulsion of the mucus.

[0041] Further advantageous is the fact that the washing device for treatments of the ear, nose and throat and the like of the present invention does not involve problems of reversing phlegm with the directing thereof towards the ear tubes.

[0042] Further advantageous is the fact that the device of the invention is simple and easy to use and can also be used in domestic contexts without the need to resort to specialized medical personnel.

[0043] Further advantageous is the fact that the device of the invention can be used, as an alternative to nasal washing, also for an eye or ear washing and, in the latter case, the temperature of the saline solution between 35° and 38° C. favours the removal of wax from the ears without the need to use tools such as cotton swabs which are ineffective, dangerous to use as well as harmful to the environment.

[0044] Although the invention has been described above with particular reference to an embodiment, given merely by way of non-limiting example, numerous modifications and variations will be apparent to a person skilled in the art in the light of the above description. Therefore, the present invention intends to embrace all the modifications and variations which fall within the scope of the following claims.
