Description

Opfindelsen angår en injektionssprøjte, der omfatter en patron, som er forsynet med en kanylefatning med kanyle, og som kan være anbragt i en patronholder, samt en over kanylen anbragt kanylebeskytter, som i den ene ende er aftageligt forbundet med kanylefatningen, og som ved den mod kanylefatningen vendende ende er udstyret med et fortykket parti eller en fortykket rand.The invention relates to a syringe comprising a cartridge provided with a cannula cannula holder and which may be placed in a cartridge holder, and a cannula guard disposed at one end which is removably connected to the cannula holder and which towards the cannula socket end is provided with a thickened portion or thickened rim.

En sådan injektionssprøjte kendes fra hollandsk patentbeskrivelse nr.Such a syringe is known from Dutch patent specification no.

133 649.133 649.

Ved det fortykkede parti eller den fortykkede rand er kanylebeskytteren friktionhhstspændt på en langsgående manchet, der er en del af kanylefatningen, og hvori kanylen er fastgjort. Således opnås en steril, lufttæt tillukket opbevaring af kanylen. Det er velkendt, at kanylens sterilitet er et væsentligt krav ved brug af injektionssprøjter. Den kendte injektionssprøjte er behæftet med den ulempe, at brugeren ikke på tilfredsstillende måde kan sikre sig, at nålen er steril. Nærmere bestemt kan brugeren ikke konstatere, om kanylebeskytteren har været fjernet forinden eller f.eks. har løsnet sig under transporten og derefter er blevet sat på igen i den oprindelige position. Brugeren har i virkeligheden ingen sikkerhed for, at nålen er steril.At the thickened portion or thickened rim, the cannula guard is frictionally clamped on a longitudinal cuff that is part of the cannula mount and in which the cannula is attached. Thus, a sterile, airtight sealed cannula storage is obtained. It is well known that sterility of the cannula is an essential requirement when using syringes. The known syringe has the disadvantage that the user cannot satisfactorily ensure that the needle is sterile. Specifically, the user cannot ascertain whether the needle guard has been removed before or e.g. has loosened during transport and has then been reattached to its original position. In fact, the user has no assurance that the needle is sterile.

Ansøgerne har udviklet en injektionssprøjte af den ovennævnte art, som er uden den nævnte ulempe. Nærmere beskrevet er injektionssprøjten ifølge opfin-delsen således udformet, at brugeren straks kan konstatere visuelt, om nålebeskytteren har været fjernet forinden.The applicants have developed a syringe of the above mentioned type which is without the disadvantage mentioned. More specifically, the syringe of the invention is designed so that the user can immediately ascertain visually whether the needle guard has been removed before.

For at opnå denne hensigt er en injektionssprøjte ifølge opfindelsen ejendommelig ved, at injektionssprøjten omfatter et sikringsorgan med et centralt hul, ved hjælp af hvilket sikringsorganet er ført ind over kanylebeskytteren, hvorhos sikringsorganet er forsynet med brudorganer, der aftageligt og irreversibelt forbinder sikringsorganet med patronen eller patronholderen, og det centrale huls mindste diameter ligger mellem kanylebeskytterens diameter og det fortykkede partis eller den fortykkede rands diameter.To achieve this purpose, a syringe according to the invention is characterized in that the syringe comprises a central hole securing means through which the securing means is inserted over the cannula protector, the securing means being provided with breakage means which removably and irreversibly connects the securing means to the cartridge or the cartridge holder, and the smallest diameter of the central hole lies between the diameter of the needle guard and the diameter of the thickened portion or thickened rim.

Ved brug af injektionssprøjten ifølge opfindelsen må sikringsorganet fjer·» nes,før kanylebeskytteren kan aftages. Man fjerner sikringsorganet ved at dreje det i forhold til patronen eller ved at udøve en bort fra patronen rettet kraft på det. Som følge heraf sønderbrydes de organer, som forbinder sikringsorganet med patronen eller patronholderen, og det således løsnede sikringsorgan kan føres tilbage over kanylebeskytteren og sluttelig fjernes. Herefter kan kanylebeskytteren aftages.When using the syringe according to the invention, the safety device must be removed before the needle guard can be removed. One removes the locking member by turning it relative to the cartridge or by exerting a force directed on it away from the cartridge. As a result, the means connecting the securing means to the cartridge or cartridge holder are broken and the securing means thus released can be returned over the cannula guard and finally removed. The needle guard can then be removed.

Brugeren af injektionssprøjten ifølge opfindelsen kan visuelt konstatere, om brudorganerne stadig er intakte, og heraf slutte om kanylebeskytteren har været fjernet forinden, og dermed om steriliteten er påvirket.The user of the syringe according to the invention can visually ascertain whether the fracture organs are still intact, and conclude from this whether the needle guard has been removed before, and thus whether the sterility has been affected.

Sikringsorganet kan have forskellige udførelsesformer. F.eks. kan sikringsorganet være et cylindrisk legeme med et centralt hul, hvoraf den nedre del samvirker eller i hovedsagen samvirker med kanylebeskytterens kant. Detcylindriske legemes nedre kant er udstyret med brudorganer, f.eks. i form af bånd, hvis frie ender er fastgjort til patronen eller patronholderen.The fuse may have different embodiments. Eg. For example, the securing means may be a cylindrical body with a central hole, the lower portion of which cooperates or generally cooperates with the edge of the needle guard. The lower edge of the cylindrical body is provided with fracture means, e.g. in the form of ribbons, the free ends of which are attached to the cartridge or cartridge holder.

I en fordelagtig udførelsesform udgøres sikringsorganet af et hult legeme i form af en kapsel, der har en nedre, åben ende udstyret med brudorganerne, og en øvre ende er udstyret med det centrale hul.In an advantageous embodiment, the locking member is constituted by a hollow body in the form of a capsule having a lower open end equipped with the breaking means and an upper end equipped with the central hole.

I den nævnte fordelagtige udførelsesform er kanten eller fremspringet anbragt inde i sikringsorganets kapsel, og forbindelsen mellem kanylebeskytteren og kanylefatningen er yderligere beskyttet.In said advantageous embodiment, the edge or projection is disposed within the cap of the fuse and the connection between the needle guard and the needle holder is further protected.

Ifølge en yderligere fordelagtig udførelsesform, hvor patronen er anbragt i en patronholder, svarer den ydre diameter af kapslens nedre ende til den ydre diameter af den mod kapslen vendende del af patronholderen, og kapslens nedre er endvidere udstyret med brudorganet i form af bånd eller tråde, som i deres frie ender er fastgjort til den mod kapslen vendende del af patronholderen.According to a further advantageous embodiment, in which the cartridge is arranged in a cartridge holder, the outer diameter of the lower end of the capsule corresponds to the outer diameter of the portion facing the capsule holder, and the lower of the capsule is further provided with the breaking means in the form of ribbons or wires. which are attached at their free ends to the portion facing the capsule of the cartridge holder.

I den nævnte udførelsesform er kapslens dimensioner tilpasset patronholderens dimensioner, så at kapslen kan betragtes som en forlængelse af holderen. Dette sikrer, at ydre kraftpåvirkninger på injektionssprøjten, f.eks. under transport, har mindre mulighed for beskadigelse af brudorganerne og løsrivelse af kapslen.In the said embodiment, the dimensions of the capsule are adapted to the dimensions of the cartridge holder so that the capsule can be considered as an extension of the holder. This ensures that external force effects on the syringe, e.g. during transport, has less possibility of damage to the fracture organs and detachment of the capsule.

Opfindelsen beskrives nærmere i det følgende ved hjælp af udførelseseksempler under henvisning til den skematiske tegning, hvor fig. 1 viser et længdesnit gennem et udførelseseksempel på en injektionssprøjte ifølge opfindelsen med sikringsorganet forbundet med patronen, og fig. 2 et længdesnit gennem et andet udførelseseksempel på en injektionssprøjte ifølge opfindelsen med sikringsorganet forbundet med patronholderen.The invention will now be described in more detail by way of example with reference to the schematic drawing, in which fig. 1 is a longitudinal section through an exemplary embodiment of a syringe according to the invention with the securing means connected to the cartridge; and FIG. 2 is a longitudinal section through another embodiment of a syringe according to the invention with the securing means connected to the cartridge holder.

Kanylefatningen er på den bort fra proppen 3 vendende ende forsynet med en cylindrisk manchet 12, hvori en i begge ender skråt afskåret kanyle 13 er monteret. En kanylebeskytter 14 slutter tæt omkring kanylen 13 og er friktionsfastspændt til manchetten 12 på kanylefatningen 8 ved hjælp af et fortykket parti eller en fortykket rand 15. Omkring kanylebeskytteren er der anbragt et sikringsorgan 16, der f.eks. kan være fremstillet af et gennemsigtigt syntetisk materiale. Sikringsorganet 16 har form som en kapsel 17, der er åben i den nedre ende, hvis sidevæg er cylindrisk, og i hvis øvre flade 18 der findes et centralt hul 19. Den del af kanlyebeskytteren 14, der befinder sig over kanten 15, strækker sig gennem det nævnte centrale hul 19.In the drawing, the number 1 denotes a cartridge. The cartridge 1 comprises a cylindrical ampoule 2 with an injection liquid 5 contained between a plug 3 in the front end of the ampoule 2 and a plunger 4 in the rear end of the ampoule. On the front portion of the vial is a neck 6 with a flange 7. The cartridge 1 further comprises a cannula socket 8 which, at a flange portion 9, is secured to the front of the vial 2 * by an aluminum ring 10. The ring 10 terminates about the vial flange and the cannula socket. a flange portion 11 of the plug 3 being positioned between the other two flanges. The cannula socket is provided on the end facing away from the plug 3 with a cylindrical sleeve 12, in which a cannula 13 cut at both ends is inclined. A cannula guard 14 terminates tightly around the cannula 13 and is frictionally clamped to the cuff 12 on the cannula mount 8 by a thickened portion or a thickened rim 15. Around the cannula guard is provided a securing means 16, e.g. may be made of a transparent synthetic material. The locking member 16 is in the form of a capsule 17 which is open at the lower end, the side wall of which is cylindrical, and in the upper surface 18 of which is a central hole 19. The portion of the cannula guard 14 which extends over the edge 15 extends through said central hole 19.

Det centrale hul 19*s diameter er mindre end kanten 15*s ydre diameter, men større end den ydre diameter af den del af kanylebeskytteren 14, som befinder sig over kanten. Undersiden af kapslen 17*s øvre del 18 ligger næsten eller helt an mod kanten 15.

Claims (3)

21. Patronholderen 21 svarer til den i den tidligere nævnte hollandske patentbeskrivelse 133 649 omtalte, og består a£ en hul cylinder 22 med et tværstykke 23, Cylinderen 22 afsluttes ved sin forende med en hals 24, hvis indre diameter nøjagtigt har en sådan størrelse, at den kan rumme patronen l's ring 10 uden friktion. For at fastlåse patronen 1 inden i patronholderen 21 er dennes forende udstyret med fremspring 25. Omkring kanylebeskytteren er der anbragt et sikringsorgan 26, der f.eks. kan være fremstillet af et gennemsigtigt syntetisk materiale. Sikringsorganet 26 er udformet som en kapsel 27, hvis nedre ende er åben, hvis sidevæg er i hovedsagen konisk, og hvis øvre parti 28 er udstyret med et centralt hul 29. Den del af kanylebeskytteren 14, som befinder sig over kanten 15, strækker sig gennem det centrale hul 29. Hullet 29's diameter er mindre end kanten 15's ydre diameter, men større end den ydre diameter af den del af kanylebeskytteren 14, som befinder sig over kanten 15. Undersiden af kapslen 27’s øvre del 28 ligger næsten eller helt an mod kanten 15. Kapslen 27 er ved den nedre ende forsynet med brudorganer 30, f.eks. i form af strimler af et gennemsigtigt syntetisk materiale, som i deres frie ender er fastgjort til den øvre del af patronholderen 21. Kapslen 27's diameter ved den nedre ende svarer til patronholderen 21's diameter. Ved brug af injektionssprøjten ifølge opfindelsen sikrer man sig først, at brudorganerne 20 og 30 stadig er intakte, som en kontrol på steriliteten. Dernæst drejes sikring s organet 16 og 26 med hånden, hvorved brudorganerne 20 og 30 brydes eller rives af. Det således frigjorte sikringsorgan skydes tilbage over kanylebeskytteren 14 og fjernes. Herefter er injektionssprøjten klar til brug. Ved anvendelsen skydes stemplet fremad ved hjælp af en ikke vist stempelstang. Det derved frembragte tryk i injektionsvæsken 5 bringer den centrale del 31 af proppen 4 til at bulne ud og udvides. Ved et tilstrækkeligt højt tryk brister den centrale del 31, enten spontant eller ved kontakt med den skråt afskårne bagende af kanylen 13. Derefter fjernes kanylebeskytteren 14, luften presses ud, og nålen indføres i patientens legeme. En yderligere forskydning af stemplet medfører, at injektionsvæsken 5 injiceres i patientens krop gennem kanylen 13.21. The cartridge holder 21 corresponds to that mentioned in the aforementioned Dutch patent specification 133 649, and consists of a hollow cylinder 22 with a cross piece 23, the cylinder 22 is terminated at its front end with a neck 24, the inner diameter of which is exactly such a size. that it can accommodate the ring 10 of the cartridge 1 without friction. In order to lock the cartridge 1 inside the cartridge holder 21, its front end is provided with projections 25. Around the cannula protector a securing means 26 is provided, which e.g. may be made of a transparent synthetic material. The locking member 26 is formed as a capsule 27, the lower end of which is open, the side wall of which is generally tapered, and the upper portion 28 of which is provided with a central hole 29. The portion of the cannula guard 14 which extends over the edge 15 extends. through the central hole 29. The diameter of the hole 29 is smaller than the outer diameter of the edge 15, but larger than the outer diameter of the portion of the cannula guard 14 which is above the edge 15. The underside of the upper portion 28 of the capsule 27 lies almost or completely against edge 15. The capsule 27 is provided at the lower end with rupture means 30, e.g. in the form of strips of a transparent synthetic material which are attached at their free ends to the upper portion of the cartridge holder 21. The diameter of the capsule 27 at the lower end corresponds to the diameter of the cartridge holder 21. By using the syringe according to the invention, it is first ensured that the fracture means 20 and 30 are still intact, as a check on the sterility. Next, the securing means 16 and 26 are rotated by hand, thereby breaking or tearing off the breaking means 20 and 30. The thus released release member is pushed back over the needle guard 14 and removed. The syringe is then ready for use. In use, the piston is pushed forward by means of a piston rod not shown. The pressure thus generated in the injection liquid 5 causes the central portion 31 of the plug 4 to bulge and expand. At a sufficiently high pressure, the central portion 31, either spontaneously or by contact with the obliquely cut back of the cannula 13. bursts, the cannula guard 14 is removed, the air is pressed out and the needle is introduced into the patient's body. A further displacement of the plunger causes the injection fluid 5 to be injected into the patient's body through the cannula 13. 1.
