Description

Oppfinnelsen angår en injeksjonssprøyte, særlig en engangs-injeksjonssprøyte, bestående av en sprøytesylinder samt en ved sylinderbunnen påsatt forsats, som bærer kanylen som en avtagbar del. The invention relates to an injection syringe, in particular a disposable injection syringe, consisting of a syringe cylinder and an attachment attached to the base of the cylinder, which carries the needle as a removable part.

Det er kjent injeksjonssprøyter, særlig såkalte engangssprøyter, av plast, der det ved sylinderbunnen er anbragt en fremstikkende kjegle, som oppviser en større boring. På denne kjeglen blir kanylen påsatt,som er forsynt med en kjegleformet boring. There are known injection syringes, especially so-called disposable syringes, made of plastic, in which a protruding cone, which exhibits a larger bore, is placed at the base of the cylinder. The cannula is attached to this cone, which is provided with a cone-shaped bore.

Denne utforming har den ulempe at det efter sprøyting av en medisinsk væske bestandig blir et visst restvolum tilbake som samler seg i den relativt store gjennomboring i forsatsen. Dette restvolum er derfor ikke brukbart, da det i sprøyte-sylinderen forskyvbare stempelet bare når frem til sylinderbunnen og all væske som er samlet i hulrommet som er tilsluttet sylinderbunnen går tapt. This design has the disadvantage that after spraying a medical liquid, a certain residual volume is always left behind which accumulates in the relatively large perforation in the attachment. This residual volume is therefore not usable, as the displaceable piston in the syringe cylinder only reaches the bottom of the cylinder and all liquid collected in the cavity connected to the bottom of the cylinder is lost.

Oppfinnelsen går ut på å fremskaffe en injeksjonssprøyte, særlig en engangs-injeksjonssprøyte, der det ikke blir noe restvolum, når man ser bort fra det meget lille kanylevolumet. The invention is to provide an injection syringe, in particular a disposable injection syringe, in which there is no residual volume, when one disregards the very small volume of the needle.

Ifølge oppfinnelsen er injeksjonssprøytenkarakterisert vedat den ene enden av kanylen rekker frem til sylinderbunnen. En spesielt fordelaktig utførelsesform erkarakterisert vedat forsatsen oppviser en innsatsboring, i hvilken kanylen rekker inn med sitt ved enden anordnede innsatsstykke. According to the invention, the injection syringe is characterized in that one end of the cannula reaches to the bottom of the cylinder. A particularly advantageous embodiment is characterized by the attachment having an insert bore, into which the cannula reaches with its insert arranged at the end.

Innsatsboringen og innsatsstykket er konisk utformet.The insert bore and the insert piece are conically designed.

Derved oppnås at det ikke kan samle seg noe restvolum i forsatsen ettersom stempelet er forskyvbart praktisk frem til kanylen selv, når den når sin endestilling. Thereby it is achieved that no residual volume can accumulate in the attachment, as the piston is displaceable practically up to the cannula itself, when it reaches its end position.

På tegningen er det vist en utførelsesform som eksempel. The drawing shows an embodiment as an example.

Sprøytesylinderen 1 har en sylinderbunn 2. Ved sylinderbunnen er det påsatt en forsats 3. Denne forsatsen 3 har en innsatsboring 4, i hvilken kanylen 5 med sitt ved enden anbragte innsatsstykke 6 er innsatt. Innsatsstykket oppviser en bærer 7, på hvilken en beskyttelseshylse 8 er påskjøvet. Innsatsboringen 4 og innsatsstykket 6 er utført koniske. The syringe cylinder 1 has a cylinder base 2. An attachment 3 is attached to the cylinder base. This attachment 3 has an insert bore 4, into which the cannula 5 with its insert piece 6 placed at the end is inserted. The insert has a carrier 7, on which a protective sleeve 8 is pushed. The insert bore 4 and the insert piece 6 are made conical.

Ved denne utformingen av en injeksjonssprøyte rekker kanylen 5 med sin ende 5a inn til sylinderbunnen 2. Derved blir det ved sprøyting bare igjen et lite volum i kanylen. På den måte unn-"går man det restvolumet som ved kjente sprøyter samler seg i den større gjennomboringen. With this design of an injection syringe, the cannula 5 with its end 5a reaches into the cylinder base 2. Thereby, when spraying, only a small volume remains in the cannula. In this way, the residual volume which with known syringes collects in the larger bore is avoided.
