Dental douche

Abstract: A dental douche comprising three zones with pressurised water: The jet (1), of individual character, and changeable, which can be screwed to the two-part stem (2) which to which, in turn, the water is delivered from a small flexible tube (9a) fitted directly to the tap with a suitable connection using a clamp and pressure screw to adjust to the tap opening, thereby avoiding leaks. A flexible strip can secure this mechanism to the tap. The tap connection may be by means of a bowl (12a) pressed onto said tap.

Description: BACKGROUND AND SUMMARY This invention refers to a dental douche with a new system for cleaning teeth, the gingival groove ( between gums and tooth) and the spaces between the teeth , using pressurized water, at the required temperature, to remove all remains of food or residue. The two-part design of the stem of this invention enables water to be mixed with anti-inflammatory and antiseptic medication and liquid dentifrice . In this process only the pressure of the tap water is necessary ; in this way, hot and cold water may be mixed as required . Given the simplicity of the system it is assumed that it will not be expensive to acquire and that maintenance costs will be zero . In operation it does not cause unpleasant sounds, and there are no risks involved in its use. After use, the cleaning of the dental douche may, because of its ease of assembly, even include its sterilization using chemical procedures (antiseptic products) or physical procedures( boiling water) so avoiding subsequent risks of infection . It is , thanks to its reduced size(little more than a toothbrush) , easily transported. Other dental cleaning mechanisms using pressurized water driven by electrical pumping devices already exist. However , the following difficulties arise with such electrical pumping devices : They enable anti-inflammatory and antiseptic medicinal products to be mixed (but with a greater potential for deterioration of the apparatus). They are, because of their weight and size, difficult to transport. They are noisy. They were also other dental douche devices on the market which connect directly to the tap, but they have the following defects : They were hard to fit to the tap, freely loosing water and therefore , the pressure for cleaning the teeth (see for instance US-A-2.219.813). If water pressure was too high ,the device would shoot off the tap and, if too low, it was insufficient to clean . Water and medicinal products could not be mixed . Benefits provided by this invention are revealed in the specifications although some of the most notable are described below , by way of illustration and without limitation : Ease of assembly. Ease of cleaning , so that it can be completely sterilized. Economy of manufacture. Medicinal products such as antiseptics or anti-inflammatories can be mixed with the water, without need of using any additional element to introduce the cleaning agent , considering that the mixture between water and medical substances takes place inside the device . Absence of noise . With a change of jet, this device can be used as a vaginal douche.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In line with the attached drawings , the Dental Douche as shown in Fig1 performed by a jet (1) with a pourer tip at 90 a with a convex end (2a), at its wider end provided with two or more ribs (P) on the sides which arch in concave form , pressing on the end of the housing until they fit into the housing where an O-ring (10a) is placed inside . The casing (20) with the internal lengthwise duct , forming inside chamber (11) is stepped at the end opposite the jet . A further O-ring (3a) is fitted at the end opposite the jet on a mixing tube (4a) with a screw plug (H) against which a seal is fitted (5a) each for which with an O-ring (6a and 7a) Fig 1 between the casing (20) and the outer chamber (D). The seal ends with a nut (8a) on the tube (9) connected to the tap (G). The hollow stem or handle is provided with an external chamber (D) , along which there is a cylinder, likewise hollow, which forms the inside toothpaste in the outer chamber (D), with the water flowing trough the inside chamber (11) . A screw plug (H) is placed over the mixing tube and it covers an opening through which the medicaments or liquid dentifrice are placed in the outer chamber of the stem. The tap securing system is performed by a hollow cylinder (12d) which may be transparent, with a hole at the top (M) which is larger that the one at the bottom (N) . The top of the cylinder has a outside thread (O) to fit the pressure plug (11d). The pressure plug (11d) is the second element comprising the system. The third part is shown in figures 3 and 4 as a flexible tube (9d) with circular ribs (Q) at the top to allow it to fit against the rib (17f) in the bottom of the hollow cylinder so as to connect them. One circular rib (Q) is pressed against the rib (17f), the water pressure ensures that they do not move . As a result , the tube is perfectly adjusted to the lower opening (N) of the hollow cylinder . The pressure plug (11d) consists on three parts in this design. Figure 2 shows the cylindrical cover (11c) with an inside thread for adjustment to the hollow cylinder of the capsule (12d). The top of the plug , shown in Fig.3 is provided with a hole in the middle (Z), for a screw to link to the inside cylinder of the plug (13d) Fig5. The inside cylinder of the plug (13d) is the second element and is open at the bottom , inside the cylinder is also threaded for a screw(W) of the same diameter ,with a screw top ( 16d) inside . The inside screw (w) has a rubber cylinder (17g) linked to it with an outside head of greater diameter which contacts with the tap to prevent movements and damage to the tap (G) and it is to this element (G) that pressure is applied when the plug (13d) is screwed up , fitting the tube (9) against the opposite side of the tap. This compresses the rubber cylinder against the side in the opening and against the tap, preventing leakage of water or other fluids. When tightened , the cylindrical cover (11c) directs force downwards but not sideways , so maintaining the distance to which the internal lengthening screw(W) was set . Water flows when the tap(G) Figs 1 and 6 is opened , first in the inside chamber (11), through two facing holes (E) , one distal to the other proximal , under pressure difference , form the internal to the external or surrounding chamber where pressure difference . This enables dosing of the medication to be used which was inserted through the hole on the furthest third of the outside of the stem through screw plug (H) . Pressure then increases in the internal chamber as dissolution takes place , then flowing once more through the internal chamber (11), the liquid emerges through the jet (1). Fig.6 shows the adapter unit in this last design connected to the tap, shown in trace form. To connect the adapter in this last design , the plug is completely unscrewed and the tube placed in the mouth of the tap which was inserted through the side opening . Held with one hand while inserting the plug with the other, screwing it up tight so as to completely fit the tube by the traction on the opposite side. This compresses the tube which is pressed against the opposite side of the mouth and against the tap thanks to the elasticity of the rubber, so preventing leaks. It will be almost impossible to move the apparatus forward expect in the case of some taps of unusual design. The assembly as a whole is encased so that any fortuitous leaks when the tap is opened will hardly ever be a nuisance to the user nor cause any loss of pressure. Another possible tap attachment is shown in Fig.1 and consists of a shank (17a) fitted into the tube by its cylindrical tip (17b) , the end of which is slightly tapered , with outside step- like identations to ensure that it is secured against the inside of the tube . The other end of the shank (17e) Fig.1, fits into the bowl seal (15a) on the outside of which there is a flexible washer (13a). The tap connection has a plunger (14a), shown in Fig.1 , inside the bowl housing (12a) , shown in Fig.1 , into which the cylindrical seal (15a) is fitted. The tap (G) is inserted here and is pressed against it by means of the flexible washer (13a) . There is a O-ring (16a) Fig.1 at the top of the tap. A securing nut (11a), surrounds the bowl. The upper base (L) of the bowl is closed (Fig.1).
