Definitions

  • the invention relates to a fastening mechanism for needle systems according to the preamble of patent claim 1.
  • the known injection device is used to inject selectable amounts of liquid from an ampoule or carpule equipped with a piston.
  • the needles are inserted by screwing on according to the prior art.
  • the rear end of the needle pierces the membrane, which enables medication to be expelled through the needle when the stopper is moved forward.
  • the disadvantage here is that rubber abrasion occurs when the needle is screwed on by means of a rotary movement. These rubbed rubber particles can often be found in the drug and can be injected into the human body.
  • the invention seeks to remedy this.
  • the invention has for its object to provide a fastening mechanism for needle systems of injection devices, through which a simple and hygienically clean solution is created.
  • the invention solves the stated problem with a click closure, with which the needle is simply connected to the cartridge or the injection device without rotating movement, which has the features of claim 1.
  • the fastening mechanism with click closure comes about through a fastening structure with click cams or catches on the needle holder and corresponding counter elements on the carpule or the carpule holder containing the carpule.
  • FIG. 1 shows a needle holder according to the prior art.
  • Fig. 3 shows a carpule
  • the needle holder is composed of the sleeve 6 provided with an internal thread 10 or with an external thread (not shown) and the needle receiving bearing 11 in which the needle 7 is held. Both parts are made in one piece.
  • the internal thread is screwed onto the mating thread of the cartridge, causing the needle to pierce the rubber membrane and medication to be expelled through the needle.
  • this type of fastening has the disadvantage that rubbed rubber particles can often be found in the medication.
  • the needle holder 3 shown in FIG. 2 avoids this problem.
  • the needle holder 3 consists of a sleeve 6 with a needle receiving bearing 8.
  • the sleeve contains at least two click holders 2 with click cams 1 formed thereon.
  • the needle holder 3 forms a click lock by pushing the needle holder 3 onto the carpule 4 is and the click cams 1 engage resiliently in the threads of the carpule 4.
  • the needle holder 3 can be unscrewed by rotating the carpule 4 or a carpule holder containing the carpule 4 or can also be pulled off with force.
  • the click cams l are arranged so that they correspond approximately to the pitch of the thread.
  • the click holders 2 are recessed so that in the case of an unfavorable positioning, that is, when the click cams (1) come to rest on the thread tip, the click holder 2 does not look out over the outer edge of the needle holder 3.
  • Distributed around the circumference of the needle holder 3 are at least two or three or more click holders 2 at a uniform angular distance from one another.
