Definitions

  • a dental syringe for elastic impression material which comprises a nozzle section and plunger section.
  • the plunger section includes a mixing chamber adapted to receive the nozzle section. When the two sections are coupled, the impression material may be extruded through the nozzle.
  • the present invention relates to a dental tool and more particularly to dental syringe for extruding elastic dental impression material.
  • the syringe includes a mixing chamber wherein the constituents of the elastic impression material may be mixed and then extruded in a facile manner.
  • Dental impression material is generally two components and comprises a base material and a hardening agent.
  • the two components must be mixed immediately prior to use; and thereafter inserted into a syringe-type apparatus for the dentists use. This procedure is generally carried out by repeatedly pressing the open end of the syringe against the mixed material to fill the syringe. It is obvious that this is a tedious procedure and is extremely time consuming. Moreover, in loading the syringe, the dentist has to be careful to avoid trapping air.
  • a syringe having two separable sections.
  • One section comprises a barrel and nozzle and the second section comprises a mixing chamber and a displaceable plunger attached thereto.
  • the barrel section includes an annular flange adapted to be closely fitted within the mixing chamber, whereby upon insertion of the barrel into the mixing chamber, the impression material is displaced into 'the syringe barrel.
  • the separate parts of the syringe are arranged in such manner that when the barrel section is inserted within the mixing chamber, the barrel aligns with the plunger so that the latter may be readily depressed into the barrel to extrude the impression material through the nozzle.
  • FIG. 1 is a perspective view of the device of the present invention in a disassembled form
  • FIG. 2 is a, longitudinal cross-section of the device of the present invention in an assembled form
  • FIG. 3 is a cross-sectional view taken along lines 33 of FIG. 2;
  • FIG. 4 is a longitudinal cross-sectional view of the device of the present invention in disassembled form.
  • the device of the present invention generally comprises a tubular barrel 10, an enlarged tubular mixing chamber 12, and a plunger 14.
  • the tubular barrel 10 converges at one end into a nozzle 16 which is preferably angularly disposed thereto.
  • the barrel 10 includes, at its opposite end, an annular flange or disc 18 which is adapted to snugly fit within the mixing chamber 12.
  • the plunger 14 includes, at its distal end, a button 20 for depressing the plunger within the syringe.
  • the barrel 10 may also include projecting flanges 22 which are used as finger grips and which are positioned so that they abut the rim 24 of mixing chamber 12 when the barrel assembly is inserted within the mixing chamber.
  • the tool is constructed of such size and configuration so that it is readily inserted into the mouth of a patient in such manner that the nozzle 16 may be placed in close proximity to the preparation to be impressed.
  • the syringe of the present invention may be constructed of any non-toxic material and is preferably constructed of plastic.
  • the syringe of the invention is shown in an assembled state.
  • the annular flange 18 of the barrel l0 closely fits within the mixing chamber 12 to engage the base of the chamber.
  • the flange 18 is preferably includes a disked out recess 26 adapted to assist the flow of the impression material into the barrel 10 when same is inserted within the chamber 12.
  • the base of chamber 12 includes a depression 28 adapted to house the plunger head 30 when the plunger is fully extended thereby providing an essentially flat surface for mixing the constituents of the impression material.
  • the depression 28 forms a stop means to prevent the plunger from disengaging the mixing chamber section.
  • the barrel assembly and plunger assembly are constructed in such manner that when the barrel assembly is inserted within the mixing chamber 12, the interior diameter of the barrel will correspond to the plunger head 30 so that the latter may be readily inserted within the barrel 10.
  • the mixing chamber 12 further includes a tubular extension 30 partially housing said plunger 14 and providing suitable retaining and alignment of said plunger.
  • the finger grips 22 are adapted to abut against the rim 24 of the mixing chamber 12 when the annular flange 18 is fully inserted within the mixing chamber 12.
  • the dimensions of the flange 18 are such that it is snugly accommodated with the chamber 12 so that the dental impression material is completely forced within the barrel without leakage around the edges of the ring 18 and the chamber 12.
  • the plunger and mixing chamber section of the apparatus is held in a vertical direction so,
  • the plunger head 30 rests within the depression 28 to form a solid mixing base within the chamber 12.
  • the two components of. the impression material are added to the mixing chamber 12 and are mixed to the proper consistency such as with a spatula.
  • the barrel section 10 is then inserted into the mixing chamber 12 so that the conical section 26 of the annular ring 18 abuts against the floor of mixing chamber 12. In such manner, the mixed impression material abuts the base of the mixing chamber 12, the barrel 10 will be filled with the elastic impression material.
  • the plunger 14 is depressed by exerting pressure on button 20. This action will cause the plunger head 30 to move forward compressing the material into the barrel 10 and nozzle 16 and thereafter extruding the impression material through the nozzle 16.
  • the elastic impression material may be delivered to the preparation.
  • a preloaded mixing chamber which contains the two components of the impression material separated by a partition and pressure cap.
  • the partition would be removed and the materials mixed, and thereafter the barrel is inserted through the pressure cap.
  • a dental impression material injecting syringe which comprises a tubular barrel, said barrel including a nozzle at one end and an enlarged annular flange at the other end, said barrel further including finger grasps intermediate said flange and nozzle;
  • a tubular mixing chamber dimensioned to closely receive said annular flangefand a plunger mounted through the base of said chamber and positioned in alignment with said barrel when said flange is positioned in said mixing chamber, said plunger having a head dimensioned to closely fit within said barrel.
  • annular flange includes a disked out recess.
  • a tool according to claim 1 which is constructed of plastic.
