Opfindelsen angår et redskab til manuel brydning af en med brudanvisningslinie forsynet ampul til medikamenter og andre flydende emner og af den i indledningen til krav 1 angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a tool for manual refraction of a ampoule provided with medication line and other liquid items and of the kind specified in the preamble of claim 1.

5 Hidtil kendte redskaber af denne art, f.eks. fra dansk fremlæggelsesskrift nr. 139.609, er behæftet med den ulempe, at glasstøv fra brydningen ødelægger ampulindholdet.5 Prior art tools of this kind, e.g. from Danish publication no. 1399.609, the disadvantage is that glass dust from the refraction destroys the ampoule content.

Redskabet ifølge opfindelsen er ejendommeligt ved det i den kendetegnende del af krav 1 angivne. Derved tilvejebrin-10 ges et redskab, hvor manuel brydning af en glasampul kan ske, uden at medicinsk personale risikerer at beskadiges af den takkede glaskant ved ampullens brudlinie, og som følge af den et bestemt sted i forhold til brudanvisningslinien beliggende udblæsningsåbning er der sikkerhed for, at redska-15 bet ikke hindrer glasstøv fra ampulbrydningen i at undslippe, idet glasstøv fra brudstedet ledes ud gennem udblæsningsåbningen og derved i mindre grad bliver tilbøjeligt til at ledes ned i den brudte ampuls indhold. Åbningerne i redskabet må til denne effekt have en vis størrelse uden dog at 20 være så store, at en fingerspids via en sådan åbning kan komme i berøring med den inden for åbningen beliggende, skarpe brudkant på ampulhalsen.The implement according to the invention is peculiar to that of the characterizing part of claim 1. This provides a tool where manual refraction of a glass ampoule can occur without the risk of damage to the thanked glass edge at the vial line of the ampoule by medical personnel, and as a result of the outlet opening located at a particular location relative to the vial line, that the tool does not prevent glass dust from the vial refraction from escaping, as glass dust from the rupture site is discharged through the outlet opening and thereby becomes less likely to be discharged into the contents of the broken vial. The openings in the implement must have a certain size for this effect without, however, being so large that a fingertip via such an opening can come into contact with the sharp rupture edge of the vial inside the opening.

Ved det i krav 2 angivne præciseres en særligt enkel udførelsesform, som er materialebesparende.The specification of claim 2 specifies a particularly simple embodiment which is material saving.

25 Ved det i krav 3 angivne præciseres en særligt enkel udførelsesform for et snaplåsorgan.The specification of claim 3 specifies a particularly simple embodiment of a snap-lock member.

Ved det i krav 4 angivne præciseres en forenklet udførelsesform med mulighed for materialebesparelse, og hvor redska-In the claim 4, a simplified embodiment with the possibility of saving material is specified, and

med sin øverste ende 2 at klemmes elastisk eftergiveligt forbi en ampulhals' tykkeste del, der er vaseformet eller dobbeltkonveks. Redskabets 1 nederste ende 3 kan ligge løst an mod ampullens skulder. For at blive anbragt således på 5 ampullen, må redskabets øverste ende 2, efter indføring af den nederste ende 3 omkring ampulhalsen, udspiles radialt indtil den har passeret ampulhalsens tykkeste del,og en glasstøvudblæsning kan ske mellem ampullen og redskabets ene ende, fortrinsvis ved den nederste ende 3.with its upper end 2 being elastically clamped resiliently past the thickest vase or double convex section of the vial neck. The lower end 3 of the implement 1 may lie loosely against the shoulder of the ampoule. In order to be positioned thus on the ampoule, the upper end 2 of the tool, after insertion of the lower end 3 around the ampoule neck, must be radially played out until it has passed the thickest part of the ampoule and a glass dust blowout can occur between the ampoule and one end of the tool, preferably at the end of the ampoule. bottom end 3.

10 Fig. 3 og 4 viser snit gennem et redskab 1A svarende til det i fig. 1 og 2 viste, men hvor et antal radialt indad-rettede fremspring 4 udgør et snaplåseorgan ved redskabets 1A øverste ende. Også her er redskabets udformning således, at en udblæsningsspalte kan dannes ved den neder-15 ste ende 3.FIG. 3 and 4 show sections through a tool 1A similar to that of FIG. 1 and 2, but wherein a plurality of radially inward projections 4 constitute a snap-locking member at the upper end of the implement 1A. Here, too, the design of the implement is such that a blowout gap can be formed at the lower end 3.

Fig. 5 viser et snit gennem et cirkulært redskab 1B, hvor låseorganet udgøres af en ringformet, korsétformet del 5 på legemets inderside til tætsluttende at fastholde redskabet 1B mellem ampulhalsens tykkeste del og ampullens 20 skulder. Her kan redskabet 1B fastspændes på ampulhalsen mellem 2 og 3. Åbninger 6 hindrer, at overtryk opbygges i redskabets 1B indre under ampulbrydningen, hvor glasstøv blæses ud af åbningen. Denne kan eventuelt erstattes af en udsparing eller spalte ved den nederste ende 3.FIG. 5 shows a section through a circular tool 1B, wherein the locking means is an annular corset-shaped part 5 on the inside of the body to firmly hold the tool 1B between the thickest part of the vial neck and the shoulder of the vial 20. Here, the tool 1B can be clamped on the ampoule neck between 2 and 3. Openings 6 prevent overpressure build up in the interior of the tool 1B during the ampoule breaking, where glass dust is blown out of the opening. This can optionally be replaced by a recess or gap at the lower end 3.

25 Fig. 6 viser et snit gennem et cylinderformet redskab 1C med radialt indadrettede fremspring 4, der tjener som snaplåseorgan. Udblæst glasstøv kan passere ud forbi fremspringene 4 og ud ved den nederste ende 3.FIG. 6 shows a section through a cylindrical tool 1C with radially inwardly projecting projections 4 serving as snap-locking means. Exhausted glass dust can pass out past the projections 4 and out at the lower end 3.

Fig. 7 viser et redskab 1D svarende til det i fig. 1 viste, 30 men forsynet med glasstøvudblæsningsåbninger 6, således at redskabets ender 2 og 3 kan ligge tætsluttende an mod ampulhalsen under en vis fjederkraft.FIG. 7 shows a tool 1D similar to that of FIG. 1, but provided with glass dust blowout openings 6, so that the ends 2 and 3 of the implement can abut tightly against the ampoule neck under a certain spring force.

Fig. 10 og 11 viser et redskab 1G svarende til det i fig.FIG. 10 and 11 show a tool 1G similar to that of FIG.

9 viste, men hvor der er to kredse af snaplåsefremspring, henholdsvis 4A og 8 i tilknytning til stiverne 7B, der hver har en udragende del i form af fremspringet 8 oven over 15 ringen 9.9, but there are two circuits of snap-lock projections, 4A and 8, respectively, adjacent to the struts 7B, each having a protruding portion in the form of the projection 8 above the ring 9.

Som det fremgår af fig. 12, fastholder redskabet 1H ampulhalsens 11 tykkeste del 12 mellem fremspringene 4A og 8, medens ringene 9 og 10 og stiverne 7B holder hinanden på plads, således at ampullens 13 ampulhals 11 efter sin af-20 knækning langs brudlinien 14 fra ampullens hoveddel 15 fastholdes i redskabet 1H.As shown in FIG. 12, the tool 1H retains the thickest portion 12 of the vial neck 11 between the projections 4A and 8, while the rings 9 and 10 and the struts 7B hold each other in place so that, after its breaking off, along the breaking line 14 from the vial body 15, the tool 1H.

Ampullens 13 timeglasformede del er her benævnt 16 og udviser en konkav/konveks ampulhalsoverflade, medens den tykkeste del 12 er vaseformet med en dobbeltkonveks ampul-25 halsoverflade.Here, the hourglass-shaped portion of the ampoule 13 is designated 16 and exhibits a concave / convex ampoule neck surface, while the thickest portion 12 is vase-shaped with a double-convex ampoule neck surface.
