The body also comprises a second portion constituted by two coaxial bell members 28, one of the bell members being adapted to be inserted in the nostrils. The cylindrical hand grip 27 of the apparatus is constituted by two sealingly joined half members 29 and 30. Push bottom 20 and opening 7 and pressure control means 5 are arranged in the first half member 29, while injector 3 is arranged in the second half member 30 and has shaped surfaces adapted to make the bell members 28 to couple. Discharge means 4 in form of a cavity or interspace is provided between the bell members 31 and 32 and its size may be varied by changing the bell members in order to obtain a large or narrow cavity or no cavity at all when the bell members walls are in contact- The second half member 30 has spacer members 33 arranged along a circumference at the connection region of the bell member 31.
These spacer members are constituted by pro j ectio ns associated with the half member 30 and adapted to support the bell member 32.
The first bell member 31 has a substantially truncated cone shape having a base 34, with an edge 35 for coupling to the half member 30, and an edge 36 abutting the half member 30. An opposite end has an outlet 37 for the liquid micelles jet. According to a further aspect of the invention, such outlet 37 extends also on the side surface of bell member 31, for example in the form of longitudinal slit. 129426/3 The second bell member 32 has a first cylindrical region 44 one end thereof being adapted to couple to the half member 30 forming a discharged washing liquid collect chamber 39. The seal of said collect chamber 39 is provided by seals or gaskets 38 arranged in a seat formed in the half member 30.
A second region of bell member 32 has a truncated cone 45 having an end provided with a tapered region 41, having a decidedly reduced diameter, followed by the micelle jet outlet 40. The union of cylindrical region 44 and truncated cone 45 of bell member 32 has a channel 46 formed by the wall of the truncated cone 45 and by an edge 42 extending from the cylindrical region 44. Any possible oscillation of the cylindrical region 44 is prevented by projections 33. Channel 46 has apertures 43 connecting the collect chamber 39 with the outside for allowing to collect the washing liquid possibly present outside wall 45 of member 32. For the same reason, bell 45 has planar regions on its surface (not illustrated in the drawings) angled towards said apertures 43 to promote the discharge of soiled liquid.
At least the bell members 31 and 32 and the injector are coaxial while the axis of conduit 8 is staggered with respect to such members and injector.
Injector 3 is constituted by a conduit 43 associated with the half member 30 and a first end of the conduit faces chamber 6. A second end of conduit 48 has a nozzle 49 for ejecting pressurized air. A cover 50 is provided above the conduit 48 and nozzle 49 and has a slightly greater diameter than the diameter of conduit 48 allowing to draw liquid by virtue of the ventur'i effect by crossing the volume comprised between conduit 48 and cover 50.
The operation of the apparatus according to the invention is apparent from what has been described and illustrated. With particular reference to the figures, considering the situation where the push-button 20 is not depressed, pressurized air enters hole 7 in chamber 6 and is therefrom partially discharged to the outside through opening 23, slit 25 and conduit 9 and partially sent to the injector 3. In this situation, the air cannot prime the venturi effect: the air at the exit of the injector has no micelles of washing liquid.
Considering the situation where the push-button 20 is depressed, air enters chamber 6 through opening 7 and therefrom goes to the injector because the passage through opening 23 is blocked by the push-button 20. The air exiting the injector nozzle is in this case capable to prime a venturi effect and therefore a jet of micelles of washing liquid exits the apparatus.
In case the pressure in chamber 6 is greater than it should be, when the push-button is closed, the pressure control means 5 is activated and particularly the cursor 10 compresses the calibrated spring 12 which opens conduit 8 and allows pressure which exceeds the calibration of the spring to be released.
The collection of washing liquid, exiting the nose and entering the apparatus, in chamber 39, is obtained by letting the liquid pass in the cavity 4 connected to chamber 39, and letting the liquid dripping along the external wall of the external bell 44, pass through the apertures 43 comprised in the collection region 46.
It has been seen in practice how the apparatus according to the invention is particularly advantageous as it can be used regardless of the type of pressurized air delivery device. Furthermore, the apparatus has improved properties of nasal cavities washing and of collection of the soiled liquid. Further advantages of the invention regard the possibility for the use to activate the atomizing action and to adapt the apparatus to his or her requirements by substituting one or more of the bell members.
The apparatus according to the invention is susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept. All the details may furthermore be replaced with other technically equivalent elements.
In practice, the materials employed, as well as the dimensions, may be any according to the requirements.
