Definitions

  • the present invention relates to an interdental cleaning brush consisting of two helically wound wire sections with bristles held therebetween for cleaning interdental spaces and adjacent natural and artificial teeth and necks, crowns, bridges and implants and superstructures of all kinds.
  • an interdental brush is shown, which is interchangeable and pivotally fixed in a holder.
  • This interdental brush, as well as the first described cleaning brush, is used by the dentist, who can see very well what he is doing and also professionally bring the appropriate exercise to allow easy introduction of such brushes.
  • US 2004 / 0154115A discloses a cleaning brush for cleaning lumens of surgical instruments.
  • This brush has the above-mentioned structural design.
  • the area of the wound wires is designed to be relatively long after the bristle-facing area.
  • the two helically wound wire sections are not closed at the inlet end, but at the inlet end opposite end, which is also designed in a loop that forms a handle for the cleaning brush.
  • the wire sections are made of stainless steel wire and in addition to iron additionally contains chromium, manganese and nitrogen in the chemical composition with a manganese content of more than 2 , 5% by weight.
  • the wire of such a brush is highly flexible and extremely resistant to breakage. According to the statements in this patent, this also significantly improves the introduction of the cleaning brush into interdental spaces. The flexibility of the wire will most likely reduce gingival injury, but a centering insertion effect is unlikely to be achieved.
  • the object of the invention solves an interdental cleaning brush according to the preamble of claim 1, characterized in that at least two various portions are formed in which bristles are made of different materials or of bristles of different thicknesses, wherein at least one in the insertion direction first portion is provided with bristles which are more flexible than the bristles of the subsequent section, so that the first portion of the Introduction of cleaning brushes in Zanh handled behalf facilitated.
  • Figure 1 is an interdental cleaning brush in side view
  • Figure 2 shows a simple embodiment of an interdental brush turn in the side view
  • FIG. 3A shows an interdental brush head with two cleaning brushes, again in a side view
  • FIG. 3B shows the same interdental brush head in the top view with the bristle trim omitted.
  • FIG. 3C shows a variant of the interdental brush head according to FIG. 3A.
  • Figure 4 shows the use of an interdental brush head in a handle with handle for use by dentists or dental hygienists and
  • Figure 5 is a handle with interdental cleaning brushes for self-use.
  • Figure 6 shows the preferred form of a double interdental cleaning brush.
  • An interdental cleaning brush of the type according to the invention is denoted overall by 1. It is formed from two helically wound wire sections 2 and between them the individual bristles 50 are held. The entirety of the bristles 50 forms the bristle facing 5. The helically wound wire sections 2 extend beyond the bristle facing area and thus form a connection to a holder 3 or a brush plate 30. In the embodiment according to FIG Holder 3 formed by an annular loop which serves to hold the interdental cleaning brush 1.
  • the bristles 50 in the bristle facing area 5 are all of the same length, so that the bristle facing 5 has a cylindrical shape.
  • Such an embodiment can also be used for the cleaning of lumens and in particular for lumens in the medical device sector.
  • This bristle-free region 12 can also be referred to as a stem.
  • the bristle trim 5 is divided according to the invention into at least two bristle trim sections.
  • the first bristle stocking portion is 51 and the at least second, subsequent bristle stocking is designated 52.
  • the first bristle stocking portion 51 is that portion that is in front of the feed side.
  • This bristle stocking portion 51 is provided with bristles 50 which are more flexible than the bristles in the second, subsequent bristle portion portion 52. The different flexibility of the bristles 50 can thereby be achieved. that either the bristles are made of the same material, but with different diameters or that the bristles are made of different materials.
  • the bristles will be made from monofilament plastic threads.
  • the bristles are made of monofilament plastic threads, the variation of the chosen materials for achieving different flexibility is less in demand, in particular for the field of use as interdental brushes. Rather, one will work here with polyamides or polyamide-like plastics and achieve the different flexibility only by the variation of monofilament threads with different diameters. In particular, thicknesses of between 1 mil and 10 mil are suitable for the interdental brush area. The unit used in the brush industry is usually mil.
  • a mil is defined as one-thousandth of an inch. One mil thus corresponds to 0.0254 millimeters. Preferably, the range for the diameter of the plastic filaments used here between 2 and 5 mil. In the interdental brush area thicker bristles are unusual and in the case of hygienic reasons, materials also hardly possible without scratching effect cause injury to the gingiva.
  • FIG. 2 shows a similar interdental cleaning brush 1 as in FIG. 1, however, with a plastic handle as a holder 3, in which the helically wound wire sections 2 are firmly anchored resp. can be anchored replaceable.
  • the holder 3 can be arbitrarily shaped. In Figure 2, it is cylindrical and provided with a corrugation so as not only to move the brush during cleaning in the longitudinal direction of the helical wound wires, but also to be able to rotate easily.
  • Bristles in the subsequent bristle stocking section Because it possible is the density of the bristles over the entire bristle stocking resp. In principle, it would be possible to reduce the density of the bristles in the introduction region 51 in the individual bristle covering sections. However, this is not the aim here. Rather, practically the same bristle density over the entire range of bristle stocking is desired. Thanks to the relative density of the bristles, also in the lead-in area 51 and by their high flexibility, the bristles 50 in this area lay back under the smallest pressure towards the helically wound wires and to the holder 3, from which the insertion force originates a relatively smooth conical lead-in surface. In this way, the introduction of such an interdental cleaning brush is also much easier in very small interdental spaces or in small diameter lumens or in an insertion opening, which is very small.
  • the interdental brush is denoted by 11 and consists here of two components, namely the handle 12 and the interdental brush head 13.
  • the handle 12 has an actual handle portion 20 and an angled end 21.
  • the longitudinal axis of the handle portion 20 is denoted by 23, while the longitudinal axis of angled end 21 denoted by 24 is.
  • the two longitudinal axes 23 and 24 enclose an angle ⁇ .
  • a receiving opening 22 is in this angled end 21 is mounted, in which the interdental brush resp. the Interdentalb ⁇ rstenkopf 13 interchangeable and rotatable about a pivot axis 25 is held.
  • such a receiving opening 22 may also be attached to the straight part of the handle for orthograde recording of the interdental brush resp. of the interdental brush head 13 or at the same time at the straight and at the angled end.
  • the interdental brush head 13 has a brush plate 30 on which a coupling element 34 is formed.
  • brush plate insert pin 32 are formed, depending on whether one or two brushes are present, a corresponding number of brush insert pins 32 are present.
  • These brush insert pins 32 preferably have a central hole, which is slightly larger than the diameter of the twisted wire sections 2, between the turns of the bristles 50 of the bristle trim are held positively and non-positively.
  • the twisted wire sections 2 are held snugly in this hole and preferably secured by means of an adhesive.
  • the bristles or the so-called bristle trim can be formally different. This will be discussed below.
  • interdental brush head will of course be made of a highly elastic plastic or of latex, with the exception of the actual brushes.
  • the most favorable and advantageous in terms of strength is the use of a polyethylene, in particular a low density polyethylene LDPE.
  • Such an interdental brush head is generally flexible in all directions.
  • FIG. 3A shows a preferred embodiment of the interdental brush head 13 in a side view on an enlarged scale.
  • this interdental brush head 13 is designed with two brushes 1, this is not mandatory for the invention.
  • the embodiment with two brushes represents a preferred embodiment, the invention can certainly also be realized in the case of an interdental brush head with only one brush 1. If only one brush is used, then the interdental brush head no longer needs to be mounted in a pivotable manner. Even a rotation is then no longer necessary. Accordingly, then the interdental brush head 13 in one piece with a handle 12 may be connected or connected to a handle 3, as previously described.
  • the interdental brush head 13 is again equipped with two interdental cleaning brushes 1 as described above and shown in FIG.

  • the brushes are inserted individually with the wire into brush insert pins and fastened with a mechanical locking system, and that these brushes or brushes, which are already fixedly connected to a brush insert pin, individually and interchangeable in the brush plate can be anchored.
  • the wire sections 2 hold the bristles 50, which in turn, as already described, in the at least two Borstenbesatzabêten different diameters or thicknesses.

  • the first bristles 51 are followed by a region with second bristles 52, which have a higher hardness.
  • the bristles 52 attached here will preferably be chosen with a diameter of 2 to 4 mils, which corresponds approximately to 0.05 to 0.1 mm. This area is the effective cleaning area.
  • the hardness is chosen here so that a good cleaning effect arises, while at the same time the hardness is not so great that the gingiva is injured.
  • a third region is preferably present with third bristles 53.
  • This brush-plate-side region has bristles 53, which again have a higher strength. These bristles have less a cleaning function but rather a supporting and protective function. This ensures that when cleaning the bristles 52 in the edge region does not bend too much and the patient does not hit the brush plate 30 or the brush insert pin 32 on the gingiva and possibly injured. He receives by these support bristles 53 a sensory perceptible resistance whereby it limits the oscillating brushing movement accordingly.

  • the plug-in plate 28 In the plug-in plate 28 at least two receiving openings 29 are formed, which are slightly conical in order to insert appropriately shaped brush insert pin 32 can.
  • the coupling element 34 may also be present between the two brush inserting pegs as another peg, which then protrudes into a receiving opening 29 which is mounted in the neck 27. All three pins 32 and 34 are then usually formed on a common plate.
