Interdental Shower Brush

Abstract

This patent application follows an existing patent filed by myself (No. FR2002480). This patent application is for the Interdental Shower Brush and is characterized by an inventive step in that it allows for oral cleaning under antiseptic conditions, the brush is rough and provides effective cleaning thanks to mini bristles, and the holes that create the shower effect are angled forward for a more efficient showering action. Furthermore, its tapered shape allows it to reach all interdental spaces, from the largest to the smallest. Finally, the latest innovation is that the device is no longer fixed to the tap, but clips on and off for storage.

Description

Title of the invention: Interdental Shower Brush

[0001] The present invention relates to a device for cleaning interdental spaces of all sizes, under dental bridges and around dental implants, by connecting directly to a water supply tap. Conventional cleaning of all these areas is usually done with dry interdental brushes or with electric devices with a water reservoir.

[0002] The device according to the invention is supplied with water from a tap onto which a quick-release ring (F) is screwed [Fig. 1]. A bayonet sleeve (E) [Fig. 2] with a quick-release fitting clips onto this ring, and this sleeve (E) carries the water to a handle via a twisted hose (D) [Fig. 2].

[0003] The handle is in two parts: the first part (C), which receives the twisted hose (D), has a regulating valve that adjusts the water flow and acts as an on / off valve. The second part of the handle (A) clips onto the first part (C) by means of a quick-connect fitting (B). This part of the handle (A) is hollow, and a dose of dental antiseptic can be inserted into it before each use. This handle (A) is available in several colors for various users. The shower brush (G) is attached to the end of this handle (A). The entire assembly disconnects from the ring (F) screwed onto a faucet and can be stored separately, with only the ring (F) remaining screwed onto the faucet.

[0004] The shower brush (G) [Fig.3], actual size on the left of the drawing and enlargement on the right, fits into the end of the handle (A). The shower brush is made of grade 5 low-density polyethylene (LDPE), semi-rigid, hollow, with a rough surface and a cylindrical-conical shape [Fig. 4]. Its total length is 2 cm. The cylindrical section is 0.4 cm long [Fig. 4 (a), with an outer diameter of 0.24 cm [Fig. 4 (b) and an inner diameter of 0.17 cm [Fig. 4 (f)]. This cylindrical section fits into the handle (A) at a 90° angle (right angle) over a length of 0.4 cm and is interchangeable. The conical section is 1.6 cm long [Fig. 4 (c)] and its outer diameter varies from 0.24 cm to 0.06 cm at its tip, giving it a taper ratio of 1:4. This allows it to fit into the widest to the narrowest interdental spaces. It attaches without glue, and the shower brush can be easily changed by simply removing and replacing it [Fig. 4](d). Its inner diameter is 0.04 cm [Fig. 4](e).

[0005] The conical part (G) [Fig. 3] is pierced with 12 holes, 3 on each face [Fig. 3] (1). These holes, with a diameter of 0.05 cm, are pierced using a needle inclined at 45° forward, and during the drilling process, asperities are created, promoting surface roughness. When water enters through these tiny holes, it generates a forward flow of water creating a shower effect along its entire length In addition, incisions on the surface of the plastic sculpt dozens of mini bristles 0.15 cm long [Fig.3] (2) over the entire conical part which becomes a brush.

[0006] The open end, with a diameter of 0.04 cm, acts as a "dental jet." The water flow from the holes, along with the textured surface and micro-bristles, creates a true shower-like brush that is activated by back-and-forth movements inside the interdental spaces, under bridges, and around implants, ensuring maximum cleanliness. Using the interdental shower brush is the same as using a conventional interdental brush and requires the user to be familiar with their mouth. The advantage of the interdental shower brush is that, with its directed and pressurized irrigation, combined with the action of an antiseptic and thanks to its textured surface and micro-bristles, by disrupting and removing dental plaque, it is an unparalleled tool for dental hygiene.

[0007] The ring (F) remains fixed to the tap; the user simply engages the sleeve (F) and opens the tap for water to flow from the shower brush, generating a continuous stream. The device uses no electricity or water tank and, being compact, can be stored nearby until needed. The brush should be replaced regularly as the bristles wear.

Claims

Demands

1. Device for cleaning and sanitizing interdental spaces, under bridges and around dental implants characterized in that it comprises a shower brush supplied by water from a tap.

2. Device according to claim 1 characterized in that the shower brush is made of semi-rigid plastic, hollow and rough on surface.

3. Device according to claim 2 characterized in that the shower brush is conical with a taper ratio of 1:4 which allows it to fit into the widest to the narrowest interdental spaces.

4. Device according to claim 2 characterized in that the shower brush is pierced with several small holes, the perforation of which at 45° directs the flow of water forward, creating a shower effect along its entire length, and the hole at its end acts as a "dental jet".

5. Device according to claim 4 characterized in that the drilling of the small holes creates asperities and that incisions on the surface of the plastic form dozens of mini bristles on the brush.

6. Device according to claim 2 characterized in that the shower brush fits at a right angle onto the handle and is interchangeable.

7. Device according to claim 6 characterized in that the handle is hollow and can receive doses of dental antiseptic and that this handle is engaged in a first handle with an "on-off" regulating valve and which itself is connected by a pipe to the city water supply.

8. Device according to claim 7 characterized in that the hose is connected to a bayonet sleeve which clips onto a quick-release ring which is itself screwed onto the head of a tap.

9. Device according to claim 8 characterized in that the entire device is not fixed to the head of a tap and can be stored to the side.

10. Device according to claim 1 characterized in that the device does not use an electric current, nor a water reservoir.
