Definitions

  • the invention relates to a construction which can also be used by people with reduced eyesight or from blind-blind patients for self-injection, primarily for the exact dosage of insulin.
  • diabetes is the widespread disease of our day, and the number of people suffering from it is arguably growing all over the world.
  • Around 300,000 diabetic patients are registered in Hungary alone.
  • a very precisely metered, injected amount of insulin is necessary to maintain the life of approximately every 6-7th diabetic.
  • With a significant antail of the patient there is a decrease in vision, possibly blindness as the patient progresses eats up.
  • the majority of insulin-dependent patients who have tras eyesight give themselves the syringe, on the one hand to make themselves independent of the medical personnel, and on the other hand to relieve the sanitary facilities.
  • the regular injection in many cases - since every sting is also associated with a psychological visit - results in such a psychological inhibition that makes regular dosing of the insulin difficult.
  • Tibor PELVAY Budapest mechanic for sanitary instruments, designed a device that is completely identical in its puncture to the HELINOS syringe, but works with a used plastic syringe, to correct some of the above machined parts.
  • This instrument is cheaper than the one made in Sweden, its handling and cleaning is easier.
  • the problem remained that the syringe can only be used by those patients who can see well and are able to dose precisely because of their age, their physical and mental condition.
  • the object of the invention was to construct such an automatic syringe which is cheap, which works with a plastic syringe once used and which is also suitable for the treatment of people with reduced eyesight or of blind patients.
  • a self-injection device with a metering device for the medical syringes used once was constructed, which consists of a syringe barrel, spray carrier and such a shooting device which secures the relative displacement between the syringe barrel and the spray carrier and actuates it with spring force becomes.
  • the front part of the syringe housing is provided with an attachment which holds the ampoule and the spray carrier is assembled with a metering device which limits the displacement of the plunger of the syringe.
  • the dosing device consists of a threaded sleeve rigidly coupled to the syringe carrier, of a threaded shaft rotating in the sleeve, of an asymmetrical push plate rigidly coupled at the end of the shaft and of a spring-loaded counter which holds the Rotation of the shaft with a click tone indicates.
  • the thread pitch of the spring-loaded counter that is to say the threaded shaft, being equal to two units of the insulin volume of the corresponding syringe plunger displacement per rotation.
  • Fig. 1 shows the side view
  • Fig. 2 the top view of the construction of the invention.
  • Fig. 2 the well-known, mass-produced, once used medical syringe is also drawn with a narrow line
  • the framed insulin bottle is also drawn with a broken line in the construction of the invention.
  • Fig. 1 the syringe house 1 is clearly visible, in which the spray carrier 2 can move so that the spring-actuated firing device 3 is pulled up during the relative displacement of the syringe house 1 and the spray carrier 2, which then turns on with the button 10 the side of the case
  • the housing 1 is expediently cut from a sheet metal and bent and provided on its front part with a projection 5 which holds the ampoule or the bottle.
  • the spray carrier
  • the metering device 4 consists of a threaded sleeve 6 rigidly coupled to the spray carrier 2, of a threaded shaft 7 rotating in the sleeve, of an asymmetrical impact plate 8 rigidly coupled at the end of the shaft and of a spring-loaded counter 9 which indicates the rotation of the shaft 7.
  • the construction of the invention works as follows: the injection needle is to be attached to the plastic syringe once it has been used (this is important because of the sterility). Then the assembled syringe is to be injected into the injection carrier 2.
  • the threaded shaft of the metering device 4 is to be adjusted according to the amount of insulin to be injected by a corresponding number of rotations.
  • the twists are displayed with the help of click tones and they can also be felt by palpation. Now the sterile protective cover of the thread should be removed.
  • the firing device 3 which is actuated by spring force, the insulin bottle is to be pushed into the neck 5 of the syringe barrel 1.
  • the Madel penetrates through the cap of the bottle and the insulin can be sucked in.
  • the plunger of the syringe can only be moved up to the asymmetrical thrust plate 8 on the shaft 8 of the dosing device, which ensures that an exact amount of medication is sucked in.
  • the suction must be repeated.
  • the construction of the invention should be based on the surface of the body so that the receiving attachment 5 touches the surface of the skin.
  • the trigger button 10 is actuated in the vertical position of the instrument, the spring-loaded shooting device 3 advances the spray carrier so that the maid penetrates into the body tissue through the epidermis. By depressing the syringe plunger, the drug dose gets into the patient's organism.
  • the instrument can also be used by people with reduced eyesight and are used with great certainty by blind patients.
  • the poorly sighted user whose movement is also uncertain and less coordinated, cannot violate the rules of sterility when using the instrument, since the syringe can be installed in the instrument so that the protective cover remains on the madel, or the housing is has been constructed so that the bottle of the drug is also kept stable and since the Madel and the drug bottle meet each other under sterile conditions.
  • the dosage of the medication and the emptying of the air can also be carried out blindly.
  • the construction of the invention not only means a remedy for people with reduced eyesight, but also favors rehabilitation, since the patient can use this instrument to remove himself from the sanitary facility, or independent of the sanitary personnel, can move freely.
  • the instrument can be mass-produced cheaply because of its simple construction.

Abstract

Le dispositif comporte un logement (1) de seringues, un support (2) de seringue et un mécanisme d'avancement (3) actionné par effet de ressort, lequel mécanisme permet le déplacement relatif du logement (1) vers le support (2) de seringue. La partie avant du logement (1) est pourvue d'un épaulement (5), et le support (2) est relié à un doseur (4) qui limite le déplacement du piston de la seringue. En outre, le doseur (4) comporte une douille filetée (6) couplée rigidement au support (2), une tige filetée (7) tournant dans la douille, une plaque de poussée (8) asymétrique couplée rigidement à une extrémité de la tige (7), et un système de comptage (9) muni d'un ressort, qui signale acoustiquement par le déclic du ressort la rotation de la tige (7).
