Definitions

  • the present invention relates t o a dental device, which performs the suction of sali a and simultaneousl works as a "dam" or barrier in order to isolate the whole dental arch or a ortion tliPi eof where the operation is to be carried out- from the patient's lip and tongue.
  • various dental devices a r e known, which are used for the suction of sal iva and/or for maintaining the mouth in an open condition and/or for moving away the tongue and lips from the zone of the operation, in order to prevent the dentist from diverting his mind so that his attention is reduced.
  • the reason why the suction of saliva is required, is that the use of certain medical substances necessitates a "dry field" to prevent them from being mixed with saliva.
  • Known devices have some drawbacks. Some of them are of a disposable type, and this is not always advantageous compared to a device of practical ly unlimited duration. There exist also devices with flexible parts (small sucking tubes), w ich may therefore be more easily broken than a rigid element.
  • the suction of saliva must be performed in a uniformly distributed fashion (at different spots), whereas some systems provide for a concentrated suction at only one spot or at most at two different spots.
  • An object of the present invention is to insure an uniform suction of saliva around the dental arch or a portion thereof where the operation is to be carried out .
  • a further object is to allow an immediate insertion of the device and to provide a retaining system which is both effective and quick to use, but which is not a nuisance for the patient. Since the device is automatically retained in its position during the operation, it wi ll not be necessary to have an assistant whose prevalent task is to occupy himself with the suction of the saliva. T is assistant may therefore be otherwise employed in order to perform other tasks.
  • Still another object of the invention is to real ize al l parts of the device using substantially rigid materials, which do not break, so that the duration of the device is practically unlimited, and it will only be necessary to steril ize the same before each operation.
  • Still a further object of the invention is to provide means serving as barriers for the tongue and for widening and moving away the cheeks and lips, in order to maintain the best possible visibi lity in the region of the operation.
  • Said means may be integrally realized with the saliva suction duct, or may be realized by using another material and thereafter fixed to the duct.
  • Fig. 1 is a perspective view of the device of the present invention, usable in the left lower half of the denta I arch ;
  • Fig. 2 is a perspective view of the device of the present invention, usable in the whole lower dental arch, wherein the means serving as barriers are not shown ;
  • Fig. 3 is a schematic perspective view of the device of Fig. 1, placed in a stable position around the left lower half of the dental arch of the patient;
  • Fig.4 is a schematic top view of two devices, one of them being used in the right half of the dental arch and the other in the left half.
  • the device comprises a substantially rigid or hardly flexible smal l tube 1, made of a l ight and not (much) traumatic material (a resin or plastics), which can be positioned around a portion of the lower dental arch of the patient (in Fig. 3 the whole of the left half of the dental arch).
  • the substantial rigidity of the small tube 1 surrounding half of the dental arch insures that it will be stable, so that no intervention of an assistant is required after it has been put in place.
  • the small tube 1 also has an upwardly convex portion 2 which extends over the dental arch, as shown in fig. 3, in such a way that the free end 6 can be connected to a known liquid suction apparatus (vacuum source).
  • the tube 1 has uniformly spaced holes (not shown) which uniformly surround half of the dental arch, used for the suction of saliva or of any liquid utilized during the operat i on .
  • the end 3 of the small tube 1 is closed.
  • the elements 4,4' are made of rigid or almost rigid material and form barriers against spatters of saliva. They are fixed or integrally formed on the duct 2 used for removing the saliva.
  • the half of the dental arch shown in Fig. 3 is therefore isolated and this circumstance facilitates the work of the dentist. It must be noted that the invention does not include in its objects the provision of means for maintaining the mouth open. Therefore, the device is less cumbersome with respect to devices which also have this function, and this means that it is not as much a nuisance for the patient as those devices.
  • Fig. 2 shows an analogous small tube 1, w ich however can be inserted around the whole of the lower dental arch. In this case too, end 3 is closed, and holes (not shown) are formed at preferably equal distances on the small tube 1 and around the dental arch.
  • part 2 of the smal l tube is upwardly convexly formed, in order to firmly retain the device on half of the dental arch, in Fig. 2, the elbow-like part
  • the barrier elements 4, 4' are not shown. However, these elements are obviously present in this case too, and their preferred form is the same as that described previously.
  • the materials used in the present invention may be of any kind, provided they are suited for the intended purpose and in conformity with law.
  • Elements 4,4' may be continuous or discon inuous. The shapes of these elements may be different from the above described ones, even if the preferred configurations are the already described ones.
  • the section of the tubular duct 1 may have different sizes and forms (rounded, square, etc.).
  • the holes on the sma I I tube 1 can be in the form of elongated slots or be disposed according to different arrangements; preferably they are equidistant, even if this is not necessarily the case.
  • a membrane may be fixed on the device of the invention (by means of already provided hooks).
  • Fig. 4 clearly shows the opposite concavities of the elements 4,4'.

Abstract

L'invention porte sur un instrument dentaire assurant la succion et l'extraction de la salive et muni d'une barrière isolant la zone de l'arcade dentaire soumise à une intervention. Ledit instrument comporte un conduit tubulaire (1) sensiblement rigide et régulièrement percé qui se place autour de la totalité de l'arcade dentaire ou seulement autour de l'une de ses moitiés, et des barrières (4, 4') fixées au conduit tubulaire. Ce dernier (1) qui assure la succion de la salive ou de tout autre liquide utilisé pendant l'intervention tient en place sans nécessiter de moyen de fixation et peut rapidement s'insérer et se positionner.
