Definitions

  • Cap for saliva ejectors provided with spacer means of the oral mucosa, and saliva ejector comprising said cap
  • the present invention is applied in the field of instruments and devices which can be used by a dental practitioner during a diagnostic or therapeutic treatment of the mouth or teeth.
  • the present invention relates to a cap for saliva ejector provided with means which prevent the obstruction thereof by the oral mucosa.
  • the invention further relates to a saliva ejector comprising such a cap.
  • a saliva ejector is an instrument commonly used by a dental practitioner during a diagnostic or therapeutic treatment of the mouth or teeth in order to remove accumulations of saliva possibly formed inside the oral cavity during the treatment.
  • Saliva ejectors generally comprise a bending cannula connected to an aspirator at a first end and closed by a perforated cap at a second end opposite the first end. At the perforated cap, the saliva ejector is placed into the mouth, preferably near the oral floor. The mucosa forming the oral floor is however flaccid. As a result, it often happens that the depression created by the saliva ejector in the oral cavity raises the aforementioned mucosa to the point that it contacts the cap, thus obstructing it.
  • the cap of a saliva ejector usually has an elongated, almost cylindrical shape, with through holes present both on the top portion of the cap and on the lateral wall thereof. Since the holes are also distributed on the lateral wall of the cap, the suction surface of the latter is three-dimensional (unlike the two-dimensional cannula inlet mouth). In the case of obstruction of the cap at the top portion, the suction can therefore continue at the lateral wall thereof.
  • the area of the suction surface of the cap is greater than the area of the cannula inlet mouth.
  • the depression at the holes in the cap is therefore lower than the depression at the inlet mouth of the cannula. The force exerted by the aspirator on the oral mucosa is thus lower.
  • the present invention relates to a cap for saliva ejector comprising:
  • ⁇ at least one lateral wall interposed between a first and a second base which are mutually opposed;
  • the cap comprises: • a plurality of spacer means transversely protruding from the lateral wall and above the first base.
  • the spacer means prevent the oral mucosa from contacting the first base and the lateral wall of the cap, thus preventing obstruction of the through holes by said mucosa.
  • the invention also relates to a saliva ejector comprising:
  • the cap comprises:
  • the adverb "reversibly" means that the cap is disconnectable from the cannula.
  • FIG. 1 shows a perspective view of a cap for saliva ejector according to the present invention
  • figure 2 shows a top plan view of the cap in figure 1 ;
  • figure 3 shows the cap in figure 1 rotated by 30° about the longitudinal axis thereof;
  • FIG. 4 shows a saliva ejector comprising the cap in figure 1 .
  • Figures 1 to 3 show a cap 1 , according to the invention, of the type "for saliva ejector", that is, a cap connectable to the free end of a cannula suitable for suctioning saliva accumulations which may form in a patient's mouth during a dental treatment.
  • Cap 1 comprises at least one lateral wall 2 interposed between a first base 3 and a second base 4 which are mutually opposed.
  • the wall 2 is preferably frustoconical in shape, with its own generatrixes preferably inclined by a few degrees with respect to a longitudinal axis 5 thereof (arranged perpendicular to the base 4). Said low inclination causes the wall 2 to appear almost cylindrical in shape.
  • the bases 3 and 4 are preferably circular and arranged orthogonally to the axis 5. Due to the frustoconical shape of the wall 2, the base 3, top in figures 1 and 3, has a width slightly lower than that of base 4.
  • the outer surface of the base 3 is preferably convex at a peripheral portion 6 where it is joined to the wall 2. The cap 1 therefore appears rounded at the junction between the wall 2 and the base 3.
  • the cap 1 has a plurality of through holes 7 and 8 made at the base 3 and a portion of the wall 2 adjacent thereto. More precisely, the cap 1 comprises, at the base 3, a through hole 7 (figure 2) preferably circular and more preferably concentric to said base 3. From hole 7, other through holes 8 branch off, shaped as grooves, which cross the preferably radially base 3 and continue longitudinally in the wall 2 over a portion thereof adjacent to base 3. The grooves 8 are preferably present in a number equal to six.
  • the cap 1 at the base 4, comprises a large opening 9 (visible in figure 3) preferably circular and more preferably concentric to said base 4.
  • the cap 1 is connectable to a cannula of a saliva ejector. More precisely, through the opening 9, the cap 1 (figure 4) can be fitted on a cannula so as to provide a connection by interlocking therewith.
  • the hole 7 and the grooves 8 allow saliva to enter the cap 1 and the opening 9 allows the passage of said saliva from the cap 1 to the aforementioned cannula.
  • the latter comprises a plurality of incisions 10 (visible in figure 3), preferably circular, made at the inner face of the wall 2, in the portion of the latter not crossed by grooves 8.
  • the incisions 10 are preferably mutually parallel, more preferably parallel to the base 4 and even more preferably concentric thereto.
  • the cap 1 further comprises a ring 1 1 connected to the wall 2 inside the latter, below hole 7.
  • the ring 1 1 is preferably parallel to the base 3 and more preferably concentric to the base.
  • the cap 1 is preferably symmetrical with respect to the axis 5.
  • the cap 1 is preferably made of polymeric material, and more preferably polyvinyl chloride (also known as PVC).
  • the wall 2 has a height preferably of 15 mm
  • the base 3 has an outer diameter preferably of 8 mm
  • the base 4 has an outer diameter preferably of 9.4 mm
  • the hole 7 has a diameter preferably of 3 mm.
  • the grooves 8 have a width of preferably 1 .5 mm and extend over a stretch of wall 2 (top in figures 1 and 3) by a length preferably comprised between one third and half of the height of the wall 2.
  • the opening 9 has a diameter of preferably 7.8 mm.
  • the ring 1 1 has an inner diameter preferably of 1 .5 mm, an outer diameter preferably of 3.4 mm, and a thickness preferably of 0.7 mm.
  • cap 1 The features of cap 1 described thus far are known. Therefore, further details are not provided.
  • cap 1 from known caps for saliva ejectors is the presence of a plurality of elements 20 extended in length and, taken as a whole, projecting from cap 1 transversely to wall 2 and above base 3.
  • the elements 20 are preferably shaped as short spines connected to the wall 2 and/or to the base 3 at a first end 21 .
  • the elements 20 are preferably straight, have a preferably circular cross-section and are preferably beveled at a second end 22 opposite the end 21 .
  • the elements 20 act as spacer means of the patient's oral mucosa from the wall 2 and from the base 3, so as to prevent said mucosa from contacting them. Therefore, the elements 20 prevent obstruction of the hole 7 and of the grooves 8.
  • the end 22 is beveled, when the elements 20 contact the oral mucosa of a patient, they do not cause pain or discomfort to the latter.
  • some of the elements 20 are preferably connected to the wall 2
  • other elements 20 are preferably connected to the base 3, more preferably at the peripheral portion 6 thereof.
  • the elements 20A protrude transversely from the wall 2.
  • the elements 20B protrude from the portion 6 both transversely to the wall 2, and above the base 3.
  • the elements 20 act as spacer means protruding transversely to the wall 2 and above the base 3.
  • this preferred arrangement of the elements 20 is such as to minimize the risk that the hole 7 and the grooves 8 can be obstructed by the oral mucosa of a patient.
  • the elements 20A in fact, keep said mucosa spaced from the wall 2.
  • the elements 20B keep the oral mucosa spaced from both the wall 2 and the base 3.
  • the elements 20A, as well as the elements 20B, are present in a number preferably equal to six.
  • each element 20A and each element 20B is preferably interposed between two consecutive grooves 8. Since the grooves 8 are present in a number preferably equal to six, between two consecutive grooves 8 there is always a pair of elements 20, one belonging to the group 20A and the other belonging to the group 20B. In addition to this, as the grooves 8 branch off from the hole 7, the elements 20B form a crown around the latter.
  • this more preferred arrangement of the elements 20 makes the risk that both the hole 7 and the grooves 8 are obstructed by the oral mucosa of a patient more unlikely. Even more preferably, the elements 20A are coplanar to respective elements 20B.
  • each element 20A is coplanar to the element 20B interposed between the same pair of consecutive grooves 8.
  • the planes in which the element pairs 20A and 20B lie are preferably passing through the axis 5.
  • this even more preferred arrangement of the elements 20 is such that they do not obstruct the saliva entry in the cap 1 .
  • All the elements 20 are preferably oriented so that the end 22 lies on the opposite side of the base 4 with respect to the end 21 .
  • the elements 20B preferably not only the elements 20B, but also the elements 20A protrude both transversally and upwards.
  • the aforementioned orientation causes the elements 20 to oppose optimally to an approach of the oral mucosa to the wall 2 and to the base 3.
  • the elements 20 are inclined, with respect to the axis 5, by an angle having a width preferably of between 40° and 70°. More preferably, with respect to axis 5, the elements 20A are inclined by an angle having a width of 66° and the elements 20B are inclined by an angle having a width of 42°. If the elements 20, instead of being straight are, for example, curvilinear, the aforesaid inclinations with respect to the axis 5 are those of a straight line passing through the ends 21 and 22.
  • the elements 20 have a length preferably of between 2 mm and 3 mm. More preferably, the elements 20A are 2.8 mm long and the elements 20B are 2.3 mm long. As said with reference to the inclination of the elements 20, if the latter, instead of being straight are curvilinear, for example, the aforesaid lengths correspond to the distance between the ends 21 and 22.
  • the aforesaid dimensions are sufficient to prevent the oral mucosa from contacting the wall 2 or the base 3 due to the aforesaid depression.
  • Figure 4 shows a saliva ejector 30, again according to the invention, comprising the cap 1 reversibly connected to a cannula 31 at the base 4. More precisely, the cannula 31 partially penetrates the cap 1 through the opening 9, so as to be connected by interlocking to the wall 2.
  • the hole 7 and the grooves 1 of cap 8 allow saliva to enter it and the opening 9 allows the passage of said saliva from the cap 1 into the cannula 31 .
