SPECIFIC DESCRIPTION The mouth rinser shown in FIGS. I to 5 comprises a mixing unit I with a central mixing tube 2 (FIGS. 2 and 3) whose connection stub 3 ensures quick connection to a coupling piece 5 fitted to the water faucet 4, in a manner ensuring that the mixing unit I is always held in the position required. The mixing tube 2 extends axially through a cylindrical container 6 designed to hold a fluid, such as a liquid medicament or a mouth wash, the arrangement being such that nit mixing tube- 2 extends through the conical cover 7 and the flat cover 8 of the container 6 in central bearing apertures 9 and I0 respectively. The mixing tube 2 is designed as a Venturi tube into whose constricted portion ll (FIG. 3) the mixing nozzle I2 of the mixture regulator 13 leads. The latter is provided with a setting means 14 and a riser l5 dipping into the fluid in the container 6. The fluid in the container 6 is drawn by the suction of the Venturi tube 11, 12 through the riser 15 into the water flow of the mixing tube 2, the arrangement being such that the mixing ratio can be regulated by the setting means 14. Th! latter can be set in about four different positions: in the first position, it permits the flow of water without any addition of medicament; in the other three positions, it permits the flow of water with gradually increased addition of medicament. Reference I6 indicates the filling stub of the fluid container, permitting the latter to be refilled with fluid on removal of the cap 17. The bottom end of the mixing tube 2 is. directly over the bottom 8 of the said container, joined by a screw thread to the portion 18' of a connexion stub 18. The bore I9 of the latter communicates with a transverse bore 20 in which a valve serving as change-over means is received and secured against turning by guide surfaces 22 which are ground on the ends of the said valve and rest loosely against the flat bottom 8. The valve 21 has two vertical transverse bores 23,24 which can be alternatively brought into a position coaxial with the bore I9 by moving the valve 21, as required. One of the two outer ends of the valve 21 carries an outlet stub which is secured to a vertical transverse bore 25 and through which the water flowing through the mixing tube 2 can flow off through the orifices 24,25 and the stub 26 into the wash basin when the valve 21 is brought into the position shown in FIG. 2. When the valve 21 is brought into the position shown in FIG. 3, the transverse bore 23 is in a position coaxial with the mixing tube 2, so that the water flows through the connection stub 18. The coupling piece 29 of a flexible metal tube 30 is connected by a cap nut 28 and a ring seal 27 to the bottom end of the connection stub I8, provided with an external thread. The valve 21 is provided with three ring seals 31 ensuring hermetic sealing of the valve in the transverse bore 20 of the connection stub 18. As FIG. 1 shows, the free end of the flexible metal tube- 30 is provided with a connection piece 32 which is removably coupled to sleeve piece 33 of the mouthpiece 34 by a bayonet catch 35 (FIG. 4), ensuring quick change of mouthpiece. The mouthpiece 34 presents a flat tubular bow 36 which is bent in horseshoe fashion and shaped after the human jaw and which is provided inside with an upper and a lower noflle row 37 and 38. Connected to the tubular bow 36 on the outside of the arc is the sleeve piece 33, and connected to it on the inside of the arc is a flat hollow tongue 39 designed for insertion into the mouth cavity. The hollow tongue 39 is also provided with an upper and a lower row of nozzles 37' and 38' along each of its two longitudinal edges.

When the mouthpiece 34 is applied, the tubular bow 36 rests with a clearance against the outside of the upper and lower teeth or jaws inside the upper and lower lips. The flat hollow tongue 39 reaches into the mouth cavity through the gap formed between the upper and the lower teeth.

For rinsing teeth arid for massaging gums with water only, the valve 2] must be brought into the position shown in FIG. 3. Moving the valve 21 into the position shown in FIGS. 1 and 2 puts the device out of operation. In this case, the water flows through the outlet 26 direct into the washing basin. For mouth care and the treatment of inflammatory mouth diseases. it is possible to add a mouth wash or a liquid medicament. which for this purpose is filled through the filling stub 16 into the container 6. By the setting means l4, it is possible to regulate the supply of fluid to the Venturi tube. Through the latter, the fluid is added to the water in the particular mixing ratio established.

When not in use, the device can easily be detached from the faucet 4.

The mouthpiece 34 is designed to be available in three or four sizes, so that every person using the device can choose and use a suitable mouthpiece. This is greatly facilitated by the bayonet catch ensuring easy changing. So each member of the family can use a separate mouthpiece.

In the embodiment shown in FIGS. 6 to 9, reference numeral 20 indicates the mixing tube line removably joinable to a water faucet. The said line extends in vertical direction through a spherical container 60 transversely divided into two sections for holding a fluid, such as a mouth wash or a liquid medicament. The filling aperture of the said container can be closed by a plug l6a provided with a grip 17a. Fitted into a transverse bore 204 of an insert 410 communicating with the mixing tube line 20 is a plunger valve 21a which serves as a change-over means and which is axially slidable between two limit positions. The valve, which is provided at its outer end with a push member 42a, has two plungers 43a and 44a which enclose a space 450 between them. The bottom portion of the mixing tube line is designed as a stub 46a, which is removably inserted into the bottom portion of the container and in whose passage is arranged a mixing nozzle 11a which acts in the manner of a Venturi tube and which communicates through a narrow dosing bore 12a and a ring channel 47a with the inside of the container 60, through a spring-loaded non-return valve 48a. Reference 26a indicates the outlet, reference 30a the flexible tube line leading to the mouthpiece 34a. Tn this embodiment again, the mouthpiece 34a presents a flat tubular bow 36a bent in horseshoe fashion and shaped after the human jaw and provided inside with a row of nozzles 37a. Connected to the tubular bow 36a on the inside of the arc is a flat hollow tongue 39a designed for insertion into the mouth cavity. This hollow tongue again is provided with an upper and a lower row of nozzles 38a along each of its longitudinal edges.

In FIG. 7, the plunger valve 210 is moved against the action of a compression spring 490 into the operative position in which the plunger 44a rests against a ring seal 50a fitted into the insert 41a and connects the mixing tube line 20 through the mixing nozzle lla to the line 30a leading to the mouthpiece 34a. When the water jet passes through the mixing nozzle 11a, it produces in the latter a negative pressure which opens the non-return valve 48a of the line leading to the container 6a. so that liquid is drawn from the container 6a and mixed in the nozzle 110 with the water flowing through.

As soon as the push member 420 is released, the valve 21a, actuated by the compression spring 49a in FIG. 7, moves to the left until the plunger 44a comes to rest against the ring seal la of the container insert 41a. With the valve in this position, the passage from the mixing tube line 24 to the mixing nozzle 11a is closed, while the passage to the outlet 26a is open.

In the embodiment shown in FIGS. and 11, reference 2b indicates the mixing tube line, 21b the plunger valve, 301: the flexible line leading to the mouthpiece, 26b the outlet and 41b the container insert with the bore b guiding the valve. Reference 49b indicates the compression spring holding the valve in the operative position.

Unlike the embodiment shown in FIGS. 6 to 9, the embodiment shown in FIGS. 10 and 1] has no stub 46a, and the valve is provided not with two plungers, but with three, viz. 43b, 44b, 52b. The middle plunger 52b has two intersecting bores 53!: and 54b, of which one, 53b, interconnects the spaces 55b and 56!: between the two outer plungers and the middle one, while the other bore 54b. located between two plunger ring seals 57b, communicates, in the operative position shown in FlG..l0, with a port leading to the fluid container 612.

In the position shown in FIG. 10, the bore 53b in the middle plunger 52b acts as a Venturi tube, so that fluid is drawn from the container 6b through the bore 54b and added to the water flowing through. When the valve 21b is released, the spring 49b pushes it into the position shown in FIG. 11, in which the plunger 43b rests against the screw 58b serving as a stop, and the mixing tube line 2!: is directly connected to the outlet 26b. In the inoperative position of the device shown in FIG. 11, the port leading into the container and passing at 5% into the bore 20b is covered by the ring seals of the plunger 44b, so that no fluid can flow out of the container 6b.

In the embodiment shown in FIGS. I2 to 14, reference 6c indicates the fluid container with the plug 160 serving to close the filling aperture, with the mixing tube line 1c. The latter communicates at its lower end with the transverse bore 20c, in which the valve 21c is axially slidable between two limits set by the stop screw 58c. Reference 46c indicates the stub which is screw-joined to the container 6c and which has a neck llc serving as a Venturi tube; the said neck communicates through a narrow dosing bore l2c, a ring channel, 470 and a bottom port 60c with the fluid container 6c. The valve 2!: is provided at each end with a push surface 420 and presents two plungers 43c and 44c which are held apart at a specific distance by the valve portion 61c narrowed in its diameter. Reference 26c indicates the outlet.

FIG. 14 shows the valve in the operative position of the device, in which the mixing tube line 20 communicates through the free plunger space 45c with the stub 46c, so that, when the water faucet is opened, water flows through the mixing nozzle 1 1c, producing a suction which draws fluid from the container 6c.

The water fluid mixture produced in the nozzle llc then flows through the flexible line (not shown) to the mouthpiece. When the valve 21c is moved into the other limit position, i.e. to the right in FIG. N, the connexion between mixing tube line 2c and stub 46c is interrupted while connexion is made between mixing tube line 20 and outlet 26c, so that the water flowing through the mixing tube line and the plunger space 45c can flow through the outlet 26c directly into the washing basin. As there is no negative pressure in the mixing nozzle llc when the valve is in that position, no fluid can flow out, despite the direct connexion between the container 6c and the mixing nozzle, because the cap 16c ensures hermetic sealing and repeated use of the device reduces the liquid level in the container 6c, resulting in a vacuum which retains the fluid in the container. However, once a certain negative pressure arises in the mixing nozzle llc which is greater than the vacuum in the container, fluid flows out through the dosing aperture 120. If necessary, though, it is possible in this embodiment to fit a non-return valve into the line between mixing nozzle and fluid container, as shown in FIG. 4.

The use of the above-described device is not confined to mouth care; the device may conveniently also be used for intimate hygiene. For this, i.e. for vaginorectal use, the mouthpiece is given the size and shape of the mouthpiece tube of an irrigator.
