Description

7707915-0 undanröjande av nackdelarna hos tidigare kända instrument medger noggrann inställning av ordinerad dos och säker påfyllning av sprutan även av synskadad person. 7707915-0 eliminating the disadvantages of prior art instruments allows accurate setting of the prescribed dose and safe filling of the syringe even by visually impaired person.

Det för uppfinningen väsentligen kännetecknande är ett vid huvuddelen roterbart lagrat fingerpåverkbart manöverelement, som via en utväxling åstadkommer doser- stângens axiella förskjutningsrörelse.The essential feature of the invention is a finger-actuable actuating element which is rotatably mounted on the main part and which actuates the axial displacement movement of the metering rod via a gear ratio.

Genom att doserstången på angivet sätt via en ut- växling påverkas av ett särskilt manöverelement, undvikes risken för att denna oavsiktligt intar felaktigt läge, exempelvis genom att vid handhavandet slå emot något föremål. Utväxlingsanordningen kan nämligen bidraga till att automatiskt kvarhålla doserstângen i det intagna läget, så att denna ej kan rubbas ur detta. Dessutom möj- liggör manöverelementet och utväxlingsanordningen väsent- ligt större noggrannhet vid bestämning av doserad mängd.By the dosing bar being actuated by a special control element via a gear unit in the specified manner, the risk of it inadvertently taking up the wrong position is avoided, for example by striking an object during handling. Namely, the gear device can contribute to automatically holding the metering rod in the occupied position, so that it cannot be disturbed therefrom. In addition, the control element and the gear device enable significantly greater accuracy in determining the metered amount.

I praktiken föredrages att det fingerpåverkbara manöverelementet består av en ratt, som är roterbar kring en mot sprutans axel vinkelrät axel.In practice, it is preferred that the finger-actuating operating element consists of a steering wheel, which is rotatable about an axis perpendicular to the axis of the syringe.

En sådan manöverratt möjliggör enkel och säker på- verkan av doserstången och kan för ändamålet vara försedd med en eller flera tydligt kännbara och/eller hörbara markeringar per varv, som kan åstadkommas medelst en kul- spärr eller liknande.Such a control knob enables simple and safe actuation of the metering rod and can for the purpose be provided with one or more clearly perceptible and / or audible markings per revolution, which can be achieved by means of a ball lock or the like.

Vidare föredrages att manöverratten via en snäck- 'växel.påverkar doserstången. En sådan snäckväxel bildar samtidigt ett tillförlitligt spärrorgan, som säkrar doser- stången i det intagna läget.Furthermore, it is preferred that the control knob via a worm gear affects the metering rod. Such a worm gear also forms a reliable locking means, which secures the metering rod in the occupied position.

Vid en utföringsform är doserstången sidledes fjäd- rande. Den kan därvid bilda ett stoppanslag för kolv- stångens ändplatta, varvid sprutan kan ges korrekt förut- bestämd dos.In one embodiment, the metering rod is laterally resilient. It can then form a stop stop for the end plate of the piston rod, whereby the syringe can be given a correctly predetermined dose.

Uppfinningen skall nedan närmare beskrivas med hänvisning till bifogade ritning. f Fig. l är ett vertikalsnitt genom en utföringsform 7707915-0 av ett instrument enligt uppfinningen med medikament- flaska och injektionsspruta applicerade i läge.The invention will be described in more detail below with reference to the accompanying drawing. Fig. 1 is a vertical section through an embodiment 7707915-0 of an instrument according to the invention with a vial and syringe applied in position.

Fig. 2 är en vy uppifrån av instrumentet enligt fig. 1, dock utan flaska och spruta.Fig. 2 is a top view of the instrument of Fig. 1, but without a bottle and syringe.

Fig. 3 är en frontvy av instrumentet enligt fig. 2.Fig. 3 is a front view of the instrument of Fig. 2.

Ett instrument för fyllning av en injektionsspruta av engångs- eller flergångstyp består av en huvuddel 1, som i ena änden uppvisar ett utrymme för applicering av en medikamentflaska 5 och i andra änden ett utrymme för applicering av en injektionsspruta 6. För applicering av medikamentflaskan kan huvuddelen uppvisa med flaskans botten resp. lock samverkande vertikala väggar la. Alter- nativt eller dessutom kan flaskan låsas genom att huvud- delens flaskutrymme uppvisar fjädrande sidoväggar eller en separat bakre fjäder (icke visad), som pressar flaskan mot den mot locket ingripande väggen la.An instrument for filling a disposable or reusable syringe consists of a main part 1, which at one end has a space for application of a medicine bottle 5 and at the other end a space for application of a syringe 6. For application of the medicine bottle the main part can present with the bottom of the bottle resp. lid cooperating vertical walls la. Alternatively or in addition, the bottle can be locked in that the bottle space of the main part has resilient side walls or a separate rear spring (not shown), which presses the bottle against the wall 1a engaging against the lid.

Injektionssprutan 6 kan fixeras på motsvarande sätt samt dessutom med hjälp av en eller flera vid huvud- delens ände befintliga hakar lb, vilka samverkar med en utkragning 6a på sprutan.The syringe 6 can be fixed in a corresponding manner and also by means of one or more hooks 1b present at the end of the main part, which co-operate with a cantilever 6a on the syringe.

För att medge korrekt inställning av doserad mängd, är en doserstång 2 förskjutbart rörlig i ett utrymme på huvuddelens undersida. Vid den i fig. 1-3 visade utförings- formen är doserstångens 2 ände 2a fjädrande i sidled och inrättad att tjänstgöra såsom stoppanslag för en på spru- tans kolvstâng 6b anbragt ändplatta 6c. ' För förskjutning av doserstângen 2 är en finger- påverkbar manöverratt 3 lagrad vid huvuddelen, så att den är roterbar kring en mot sprutans axel vinkelrät axel. För ökad greppsäkerhet är ratten 3 försedd med in- skärningar 3a. Manöverrattens 3 i fig. 1 uppåtriktade sida är försedd med en snäcka 3b, som samverkar med mot- svarande på doserstångens undersida utbildade snäckdrev i form av inskärningar 2b under bildning av en snäck- växel, som möjliggör noggrant styrd-förskjutning av doserstången samt automatisk fixering av denna i axiell led i det intagna läget. 7707915-0 Manöverratten 3 är dessutom försedd med en eller flera tydligt kännbara och hörbara markeringar per varv, som vid den visade utföringsformen åstadkommes medelst kulspärr 8 eller liknande. Med 4 betecknas en låsbricka för manöverratten 3.To allow correct setting of dosed amount, a dosing rod 2 is slidably movable in a space on the underside of the main part. In the embodiment shown in Figs. 1-3, the end 2a of the metering rod 2 is resiliently laterally and is arranged to serve as a stop stop for an end plate 6c arranged on the piston rod 6b of the syringe. To displace the dosing rod 2, a finger-actuable control knob 3 is mounted at the main part, so that it is rotatable about an axis perpendicular to the axis of the syringe. For increased grip safety, the knob 3 is provided with notches 3a. The upwardly facing side of the control knob 3 in Fig. 1 is provided with a worm 3b, which cooperates with corresponding worm gears formed on the underside of the metering rod in the form of notches 2b to form a worm gear, which enables accurately controlled displacement of the metering rod and automatic fixing. of this in the axial direction in the occupied position. The control knob 3 is furthermore provided with one or more clearly perceptible and audible markings per revolution, which in the embodiment shown is achieved by means of a ball lock 8 or the like. 4 denotes a lock washer for the control knob 3.

Det i fig. l-3 visade instrumentet användes på följande sätt: ' l. Flaskan 5 placeras i sitt utrymme. 2. Ordinerad dos inställes medelst ratten 3. 3. Sprutan 6 jämte kanyl 6e föres mot huvuddelen, förskjutes framåt och fastlåses medelst hakarna lb sam- tidigt som kanylen 6e genomträngt flaskans 5 membran 5a.p Kolvstången Gb utdrages och sprutan fylles.The instrument shown in Figures 1-3 is used as follows: The bottle 5 is placed in its space. 2. The prescribed dose is adjusted by means of the knob 3. 3. The syringe 6 together with the cannula 6e is moved towards the main part, displaced forwards and locked by means of the hooks 1b at the same time as the cannula 6e penetrates the membrane 5a.p of the bottle 5b.

Kolvstången tryckes tillbaka, varvid doser- 4. 5. stångens 2 ände 2a kommer att tjänstgöra såsom stopp- anslag för kolvstångens ändplatta 6c.The piston rod is pushed back, whereby the end 2a of the dosing rod 2 will serve as a stop stop for the end plate 6c of the piston rod.
