Definitions

  • the invention relates to an injection device for dentists with the features of the preamble of claim 1. Injection devices of this type are used in intraligamentary anesthesia.
  • the ampoule holder is held on the handle by means of a thread.
  • the present invention has for its object to significantly simplify the handling of an injection device of the type concerned here.
  • an ampoule change should be possible much faster than before.
  • the locking of the actuating rod can also be released with a bolt component comprising the bolt.
  • the locking component is expediently equipped with an extension which engages with the locking mechanism for the actuating rod.
  • the injection device according to the invention has a pistol-like structure with two trigger levers, one of which is used for dispensing the injection agent and the other for actuating the locking component.
  • This structure enables particularly simple and time-saving operation.
  • FIG. 1 shows an injection device according to the invention with a tilted ampoule carrier
  • FIG. 1 shows the injection device of Figure 1 in the position of use
  • the injection device 1 shown in FIGS. 1 and 2 has a pistol-like structure. On its handle 2, an ampoule holder 3 and a mechanism, generally designated 5, are provided which serve to guide an actuating rod 4.
  • the actuating rod 4 can in a known manner With the help of the lever 6, sections are pushed through the ampoule holder 3. It is equipped with a head 7, which acts on the stopper of an ampoule, not shown.
  • the front end of the ampoule is connected to an injection needle (also not shown), which is screwed onto the thread 8 located at the front end of the ampoule holder 3 using a holder.
  • the advancement of the actuating rod 4 causes a metered delivery of the contents of the ampoule through the injection needle.
  • the mechanism 5 serving to advance and retract the actuating rod 4 comprises three trestles 1 1, 12, 13 fastened to the handle 2, through which the actuating rod 4 is passed. Between the goats
  • the actuating rod 4 is equipped with a locking device.
  • This comprises a further perforated disc 16, which is between the trestles
  • This disc 16 has a locking function, in such a way that it allows the feed of the rod 4 without further ado, but prevents its backward movement.
  • the disc 16 is radially outside under the action of the compression spring 17. So that it constantly occupies a tilted position. The direction of the tilt is chosen so that it allows the feed movement of the rod 4, but not its backward movement.
  • the injection device 1 described is equipped with a locking component 21, with the aid of which the ampoule holder 3 can be locked in its position of use.
  • the latch component 21 comprises the actual latch 22, which with the help of a cylindrical section 23 is in a hollow Room 24 is guided in the handle 2.
  • the locking member 21 is under the action of a compression spring 25, which ensures that the cylindrical portion 23 abuts the stop 26 in the use position of the illustrated embodiment. In this position ( Figure 2), the latch 22 protrudes into the ampoule holder 3 and locks it.
  • the latch component 21 is equipped with an actuating lever 27, by means of which it can be moved backwards against the force of the spring 25. This also pulls the latch 22 back so that the ampoule holder 3 can be tilted (FIG. 1). In this position, ampoule changes can be carried out quickly and easily.
  • the actuating rod 4 Before the ampoule holder tilts, the actuating rod 4 must be pulled back. For this purpose, the locking disc 16 must be moved against the force of the spring 17 so that it allows the rod 4 to be retracted.
  • the locking component 21 can also be used for this step serving to release the locking.
  • it is equipped with an extension 28, which engages with the free end of the disk 16, on the side opposite the spring 17. The arrangement is such that the disk 16 assumes its locking function when the injection device and the locking component 21 assume their position of use (FIG. 2). Simultaneously with the unlocking movement of the locking component 21, the disk 16 is brought into such a position that it can no longer perform its locking function.
  • the actuating rod 4 is advanced by means of the lever 6 and the disk 15, which, after tilting, forms a frictional connection with the rod 4.
  • the locking is provided, which is achieved with the help of the disc 16.
  • the unlocking takes place via the extension 28 of the locking component 21, whereby the essential advantage - one-hand operation of the device, ie both the actuation of the tilting of the ampoule carrier 3 and the unlocking process take place with the hand encompassing the handle 2.
  • the actuating rod 4 is designed in the manner of a toothed rack (FIGS. 3 and 4) and that a mechanism (not shown) engaging in the depressions serves to advance the rod 4.
  • the rod 4 must be assigned a locking or unlocking.
  • Figures 3 (locked position) and 4 (unlocked position) show an embodiment with which the desired one-hand operation is achieved even with an actuating rod 4 designed as a rack.
  • the actuating rod 4 is associated with a pivotable about the axis 29 lever 30 which is under the action of the spring 3 1.
  • the axis 29 is located between the rod 4 and the extension 28 of the locking component 21.
  • the spring 3 1 acts on the rear end of the lever 30 such that the front end of the lever is pressed against the rod 4. After each of the feed movements, the front end of the lever engages in one of the recesses of the rack 4 and locks it.
  • the unlocking again serves the extension 28 of the locking component 21. Pushing the extension 28 causes the lever 30 to pivot against the force of the spring 3 1. As a result, the front end of the lever 30 moves away from the rack 4 and unlocks it.
