[0002] For the prevention and treatment of various diseases of the body cavities, in particular the oral cavity, including the For teeth and their cleaning, for the treatment of wounds and certain skin diseases, it is suggested by doctors that Liquids that are mixed or saturated with gases, especially carbon dioxide, and in which various disinfecting and therapeutic substances are present. The active substances, dissolved or suspended, are to be injected under pressure in a thin stream into the body cavity, onto the wound, or onto the skin. The liquid beige- The mixed gases and the mechanical stimulus cause increased blood flow to the affected tissues, thereby enhancing the disinfectant effect. and the therapeutically effective substances are significantly increased.

[0003] When designing devices for spraying medically effective gas-containing liquids, various circumstances must be taken into account. This must be taken into account. All parts of the device that come into contact with the liquid should be designed so that they are protected from the liquid. cannot be attacked. For example, caustic chemicals are often used in the treatment of swollen gums, Since various metals can be attacked, particular emphasis must be placed on ensuring that no metals are used for parts of a device of the type in question. which come into contact with the liquid. This is particularly important considering that various metal salts are heavy. which can cause health problems, is of utmost importance.

[0004] The device shall be designed in such a way that it is easy and safe to handle and maintains a uniform jet pressure throughout the entire operation. Treatment duration is guaranteed.

[0005] Various devices for cleaning the wound cavity have become known in which a gas-containing liquid is sprayed. A large proportion of these devices are only suitable for use in clinics or medical practices, as either their acquisition costs are too high. are too expensive or their operation is too cumbersome.

[0006] Devices of the type in question have also been developed for home use. These could However, they have not yet found widespread use, either because they are too cumbersome to handle or too expensive to operate – or because other [systems] are available. Disadvantages that deterred the public from purchasing one.

[0007] The invention is based on the objective of designing a device for spraying a gas-containing liquid in such a way that the disadvantages the known devices are to be avoided. In particular, the device should allow for easy mass production, which is suitable for the general public. Ensuring an accessible price, allow.

[0008] This problem is essentially solved according to the invention by making at least the vessel from unbreakable, preferably made of transparent plastic and that the head piece is attached to a preferably flange-shaped component enclosing the opening of the vessel. The edge can be pressed down by means of a quick-release fastener, and the flow cross-section of the riser pipe and the valve assembly is such that It is designed so that the liquid flows at a relatively low speed without turbulence friction losses to the jet nozzle, from which it is expelled in a thin stream. The beam exits at a relatively high speed.

[0009] Particularly easy operation, even for disabled persons, for example for one-handed users, can be achieved by the fact that the The quick-release fastener consists of two plastic hand levers, each with a hook-shaped end that fits securely into a notch in the head piece. are suspended in such a way that they can be swivelled around a certain angle.

[0010] In a preferred embodiment, the valve consists of a valve bolt slidably mounted in the head piece, the valve cone of which by the action of a valve spring against the edge of the bore receiving the riser pipe, and from a sealing ring, whose The lip-shaped central part is pressed against the valve bolt by the gas pressure of the liquid.

[0011] In a preferred embodiment, a hand lever is attached to the head piece, which is connected to a leg located inside the head piece. It has an eyelet and a curved underside, arranged so that its eyelet engages the valve bolt with a disc mounted on it. encloses the valve and its curved underside rests against a bearing surface of an opening in the head piece in a way that allows it to roll, so that when the leg of the hand lever lying outside the head piece is actuated, the valve pin is lifted against the action of the valve spring. becomes.

[0012] The tablets to be placed in the container containing the liquid contain at least two [unclear] when dissolved in the liquid. Substances that react with each other and emit gases, such that parts of at least one of the substances react with each part of at least one of the other substances encase, wherein the parts are preferably connected to each other by other substances not serving gas evolution or in their entirety are enclosed. The composition of the tablets should be such that the gas-forming reaction is carried out by a layer encasing the tablets. The device is controlled to maintain a substantially constant internal pressure over a longer period of time, which is reduced when the The valve produces a jet of liquid exiting the nozzles with a constant strength.

[0013] An embodiment of the device according to the invention is shown in the drawing. Fig. I shows a diagrammatic view. of the device, Fig. 2 a longitudinal section of the device, Fig. 3 a section of the head piece in a position offset by 0° to the section according to Fig. 2 Cutting plane.

[0014] The neck of a bottle-shaped vessel I that widens downwards is provided with a flange 2 which encloses an opening which is The container is large enough to allow for easy cleaning and filling. Container I is made of transparent, unbreakable plastic, which is... It is manufactured from substances used in dentistry for therapeutic or disinfection purposes and is not attacked or corroded. The size of vessel I is designed in such a way that it provides the necessary components for rinsing the oral cavity. It can hold large amounts of liquid, but on the other hand, it doesn't become unwieldy.

[0015] The opening of the vessel I is closed by a head piece 4 to which two clips 5 of a clip closure are hinged. In the In the locking position, the brackets 5 with lugs 6 engage in the slightly beveled underside of the flange 2 and press the head piece 4 against the The top of flange 2. To ensure a gas-tight seal of vessel I, a sealing ring 7 is provided, which is connected by a The enclosing ring 8 of the headpiece 4 is held in its position. The sealing ring 7 has two inwardly directed lips g which, If there is an overpressure in vessel I compared to the atmosphere, apply it on one side to flange 2 and on the other side to headpiece 4, thus... Seal container I gas-tight.

[0016] The headpiece 4 consists of two parts, namely the upper part II and the lower part I2. The upper end face of the lower part 12 is equipped with two preferably rectangular or ring-shaped notches 14 in cross-section for receiving the hook-shaped ends I3 of the locking brackets 5.

[0017] In the side walls of the upper part 11 of the head piece 4, recesses 15 are provided which correspond to the notches 14 in the lower part 12 The height and width of the recesses 15 and the notches 14 are such that the hook-shaped ends I3 have a certain amount of play. have, which allows the locking levers 5 sufficient pivoting to release the lugs 6 from engagement with the flange 2. However, the locking bars 5 should not be able to fall out of the notches 14.

[0018] In the upper part II and in the lower part 12, there are two corresponding bores and coaxially embedded with these in the lower part I2. Screw nuts 19 are provided. The upper part II and the lower part 12 are joined by means of screws i6 screwed into the screw nuts 19. connected to each other. The upper part 11 and the lower part 12 are preferably designed as substantially cylindrical bodies of revolution. In the upper part 11 is a continuous, concentric bore that runs from bottom to top, i.e., from the end face resting on the lower part I2 to the The upper end face of the upper part II, forming the upper side of the device, is expanded twice abruptly, so that an upper 21 and a lower step 22 are formed in the bore. The lower part 12 has a concentric bore that widens abruptly twice from bottom to top, provided so that two paragraphs 23 and 24 are formed.

[0019] A guide disc 26 for a valve bolt 27 is inserted into the paragraph 22.

[0020] A disc 28 is attached to the valve pin 27, against which a spring 29, supported on the shoulder 21, acts. The spring 29 presses The valve pin with the valve cone 31 is thus attached to the shoulder 23, thereby closing the bore of the lower part 12. In a section of the upper part II of A hand lever 33 is arranged in the opening through the outer side wall to the central bore, the leg 32 of which has a curved shape. The lower surface has a surface with which it rolls on the preferably flat lower surface of the opening. The leg 32 terminates in an eyelet 34 which the surrounds valve pin 27.

[0021] When the hand lever 33 is pressed against the vessel I, the leg 32 rolls down the underside of the opening and presses with its eyelet 34 the disc 28 upwards against the action of the spring 29, whereby the valve formed by the valve pin 27 and the shoulder 23 is opened.

[0022] A sealing ring 36 is inserted into the recess 24 of the lower part I2, which, when the upper part 11 is attached to the lower part 12, is separated from the The guide disc 26 is held in such a way that the bead-shaped or, in cross-section, lip-shaped inner edge of the sealing ring 36 is positioned under the The pressure prevailing in vessel I is applied to the valve pin 27, thus sealing the bore of the valve gas-tight against the bore of the upper part.

[0023] A riser tube 41 projecting into the vessel I is attached in the bore of the lower part 12. The lower part I2 of the head piece 4 has a transverse bore 55 extending to the concentric central bore in the lower part, in which a tube 56 projecting outwards from the device is attached. The end of the tube 56 is provided with a nozzle-shaped opening 58.

[0024] The mode of operation and the operation of the device is now as follows: The operator guides a hand along the vessel I and presses The handguards 5 with their projecting handles 10 move away from the vessel I. The swiveling of the handguards 5 causes the noses 6 to emerge from their position. The closed position is with the lower surface of flange 2. As the hand is moved further upwards, the hook-shaped ends I3 extend. to the inner walls of the opening 15 in the upper part II, thereby preventing further pivoting movement of the brackets 5. The headpiece 4 can so that it can be lifted from container I in one go and with one hand. Container I is now filled with water and a medication, preferably in Tablet form54, containing therapeutic and disinfectant components, gas-producing substances, and flavor-enhancing agents The contents are thrown into container I. The headpiece 4 is then placed back onto container 1 and the handguards 5 are pressed together so that whose noses 6 snap into the underside of the flange 2.

[0025] The tablets 54 dissolve slowly in the water introduced into the vessel I and thereby develop gases, in particular carbon dioxide. When the hand lever 33 is pressed against the vessel I, the valve cone 31 releases the opening at the shoulder 23, whereby the [unclear] under the Pressure of the generated gases standing liquid via the pipe 41, the concentric bore in the lower part 12 and the one in the concentric bore open, outward-leading transverse borehole 55 as well as The fluid travels through the pipe 56 to the outlet nozzle 58 and emerges there in a thin stream. When the hand lever 33 is released, the spring 29 exerts pressure. the valve cone 3I to the opening at the end of paragraph 23. If the internal pressure in vessel 1 exceeds a permissible limit due to improper operation, For example, if the pressure exceeds the limit when the device is shaken excessively or when it is heated, the valve cone3I is automatically lifted by the pressure.
