Definitions

  • This invention relates to a cylindrical ampoule with an injection needle, in which the injection needle, through which the injection liquid is expelled by means of a closure plug serving as a piston, is fitted at its end adjustment to the ampoule with a flange-like attachment fixed to the ampoule opening formed with a beaded lip by means of a cap which can be flanged over.
  • the needle is protected by a small glass tube, which is fitted over a rubber sleeve drawn on to the olive-shaped or fluted part of the needle stem.
  • Such a cylindrical ampoule must be clamped in an ampoule holder, which retains the ampoule in the correct position by spring pressure.
  • the sterile closure of the needle can be damaged by an unauthorized person removing the small tube and replacing this tube, without it being possible to detect the damage.
  • the flanged cap is preferably provided with an external thread on to which there can be screwed a holder for injection purposes and a hollow cylindrical plunger with a flange, the said holder, consisting for example of a plastic material, accommodating the cylindrical ampoule and the plunger surrounding the needle for protection purposes.
  • the plunger serving to protect the needle is unscrewed from the flange cap when the instrument is to be used and is screwed by means of its unflanged end, which is formed with a threaded bore, on to the threaded nipple of the piston and thus serves at the same time as a piston rod.
  • the needle In order to avoid the injection liquid entering the needle and thus clogging the needle due to evaporation, the needle is provided with a mandrin which is bent over at the point of the needle.
  • the mandrin When the covering sheath of the needle is withdrawn, the mandrin is simultaneously extracted therewith, 'Since the bent-over point of the mandrin hooks itself on to the inner bead of the sheath.
  • numeral 1 represents a plastic ampoule holder into which cylindrical ampoule 2 is screwed.
  • a closure plug 3 serving as a piston, which is provided with a threaded nipple 3a.
  • a plug 6 is inserted in the opening of the ampoule 2 which is provided with a beaded lip 15.
  • the injection needle 9 is put through plug 6.
  • the needle 9 is provided with an attachment 5 having a disc-like flange 13.
  • the needle 9 is surrounded by a covering sheath 8 having a flange-like rim 14.
  • the flange 13 of the needle 9 and the flange 14 of the covering sheath 8 are secured to the ampoule neck by means of the flange cap 4 having an external thread 11.
  • the lower skirt-like part of the cap 4 is flanged over around the beaded lip 15.
  • the ampoule holder 1 and a hollow cylindrical needle cover or plunger 7, which is provided with flange 12 and has at its upper end a threaded bore 3b, are screwed 0n the thread 11. When the instrument is to be used, the plunger 7 is screwed oil?
  • An ampoule-injection needle syringe unit comprising an ampoule sealed at the proximal end by a slidable closure plug serving as a plunger having a threaded nipple at its exposed end, the distal end of the ampoule being narrowed to a small flanged neck opening, a needle rigidly mounted in a plug inserted in the distal opening of the ampoule and projecting from each end of the same, said needle having a disc like flange at its almost proximal end for contacting the distal end of said plug, an elastic tubular sheath surrounding the needle, the proximal end of the sheath having a flange like rim, which is of smaller diameter than that of the needle flange, a flange cap surrounding the needle for engaging the flanged opening of the ampoule and securing thereby to the ampoule neck the flanges of the said needle and sheath, a needle cover having an open end engaging the flange cap, the
  • An ampoule-injection needle springe unit according 7 to claim 1, wherein the needle is provided with a mandrin which is bent-over at the point of the needle.
