DK 161181 B
Den foreliggende opfindelse angår en trykudligningsanordning for forseglede beholdere og af den i krav l's indledning angivne art.
5 Droger og medicin af forskellig art, som er beregnet til at blive indsprøjtet i en patient, leveres sædvanligvis i ampuller, som er forseglet ved hjælp af en membran eller en prop, der kan gennemtrænges af nålen på en injektionssprøjte. Den i ampullen indeholdte substans er i nogle tilfælde 10 leveret som en opløsning og i andre tilfælde som tørstof, der før brug skal opløses i eksempelvis vand. Dette vand eller andet hensigtsmæssigt opløsningsmiddel indføres i ampullen ved hjælp af injektionssprøjten. I begge tilflde opstår trykbalanceproblemer, når væske føres ud af eller 15 ind i den lufttætte ampul.
Fra GB-A-1.461.161 kendes an anordning til fremstilling af en opløsning af en tør ingrediens og et opløsningsmiddel indeholdt i en flaske. Anordningen omfatter to indbyrdes 20 forbundne elastiske deformerbare beholdere, hvoraf den ene indeholder den tørre ingrediens, medens den anden er luftfyldt. Beholderne er forsynet med hule nåle, som kan gennemtrænge flaskens lukkeorgan. Den luftfyldte beholder har til opgave at frembringe et overtryk i flasken således 25 at opløsningsmidlet presses over i den beholder, som indeholder den tørre ingrediens.
Formålet med opfindelsen er at anvise en trykudligningsanordning især beregnet for ampuller indeholdende giftige 30 substanser, som ikke må forurene den omgivende luft.
Dette opnås ifølge opfindelsen ved den i krav 1 anviste udformning.
35 Opfindelsen skal i det følgende forklares nærmere i forbindelse med tegningen, hvor - 2 -
DK 161181 B
fig. 1 viser et langsgående snit gennem et lukkeorgan for en ampul ifølge opfindelsen, fig. 2 et snit langs linien II-II i fig. 1, og 5 fig. 3-4 langsgående snit gennem to andre udførelsesformer.
I fig. 1 er vist mundingsddelen af en ampul 1, som er lukket tæt ved hjælp af en prop 2. Et forbindelsesorgan 3 er 10 fastgjort til ampullens flaskehals. Dette forbindelsesorgan 3 har en bajonetfatning 4 til modtagelse af et ikke vist overføringsorgan af den art, som kendes fra beskrivelsen til SE patentskrift nr. 434.700 og tjener til at overføre ampullens indhold til en injektionssprøjte 15 uden risiko for forurening. Et tætningsorgan 5 af eksempelvis TEFLON, der kan gennemtrænges af en nål, indgår i forbindelsesorganet 3, som yderligere er forsynet med en hætte 6, der strækker sig i væsentlig afstand i radial retning fra ampullens 1 flaskehals. En ringformet oppuste-20 lig ballon 7 er anbragt under hætten 6 og forbundet til et cylindrisk ballonforbindelsesorgan 8 med et væskeafvisende filter 9. Ballonen 7 står i forbindelse med ampullens 1 indre via en hul nål 10, der er ført gennem proppen 2. Ballonforbindelsesorganet 8 kan naturligvis være bukket, 25 således at bøjning af ballonen 7 undgås.
Ballonen 7 virker som trykudligningsorgan ved håndtering af ampullens 1 indhold. Når ampullen 1 indeholder tørstof, må dette først opløses i et opløsningsmiddel, eksempelvis 30 vand, der indføres ved hjælp af en injektionssprøjte. Dette vil skabe et overtryk i ampullen 1, og den overskydende luft vil blive presset ud i ballonen 7. Når den opløste substans suges op i injektionssprøjten, suges luft tilbage fra ballonen 7 til ampullen, således at undertryk i denne 35 undgås. Der er således tale om en fuldstændig lukket trykudi igningsanordning.

DK 161181 B
Fig. 3 viser en lignende udførelsesform, hvor forbindelsen mellem ampullens 1 indre og passagen 14 kan skabes ved hjælp af en ikke vist nål, med hvilken ampullens indhold overføres til en injektionssprøjte. Denne nål kan være 5 forsynet med ventileringsorganer af forskellig art som kendt fra beskrivelsen til SE patent nr. 434.700.
Forbindelsesorganet 3 er yderligere på ydersiden forsynet med en ringformet holder 17 for et ringformet oppusteligt 10 element 7, såsom en ballon, der dækker filteret 16.
Fig. 4 viser en kombination af to yderligere udførelsesformer svarende til den i fig. 1 viste. Ved den ene af de viste udførelsesformer er ballonen 7 erstattet af en 15 bælg 18. Bælgen 18 er fastgjort nederst på hætten 6, således at der under denne afgrænses et lukket rum. Bælgen 18 er trykløs i såvel sammentrukket som udstrakt tilstand. I stedet for en bælg kan benyttes et stempel-cylinderaggregat eller et lignende arrangement, hvis 20 volumen kan varieres. Ved den anden af de i fig. 4 viste udførelsesformer står ampullens indre i forbindelse med et rum, der er lukket ved hjælp af et låg 19, og hvis volumen er konstant. Hvis det konstante volumen er tilstrækkelig stort, kan det tjene som trykudligner eller buffer for 25 ampullens indre.
I tilfælde, hvor substansen i ampullen er ugiftig, kan membranen 5 og fatningen 4 for et overføringsorgan udelades.
