Abstract

Sprøyte-aktiverlngsinnretning (10) innbefatter et elastomert element (26) som er løsbart festbart til utløpsspissen (14) på en sprøyte (12), og til et gripeelement (48) som gjør det mulig å trekke det elastomere element (26) distalt langs sprøyten for anlegg mot sprøytestempelets (18) distale ende. I første og andre utførelsesformer er det elastomere element (26) innfestet mellom en mansjet (22) som passer rundt utløpsspissen (14), og et endedeksel (24) som ligger an mot stempelets (18) distale ende. Når mansjetten (22) er på plass rundt utløpsspissen (14), og endedekselet (24) ligger an mot stempelets (18) distale ende, med stempelet (18) i dets utskjøvne stilling, vil det elastomere element (26) være strukket langs sprøyten (12), slik at det utøver en pressvirk- ning mot stempelet (18) for forskyvning av dette inn i sylinderen. N7år det elastomere element (26) går tilbake til sin ustrukkede tilstand, vil det skyve stempelet (18) inn i sprøytesylinderen (16). I den første utførelsesform innbefatter det elastomere element (26) en eller to elastiske stropper med første (52) og andre (54) ender som er løsbart fastgjort til en mansjett (22). Hver stropp (26) har en mellomdel som er festet til et endedeksel (24).The syringe actuator (10) includes an elastomeric member (26) which is releasably attachable to the outlet tip (14) of a syringe (12), and to a gripping member (48) which allows the elastomeric member (26) to be pulled distally along the syringe for abutment against the distal end of the syringe plunger (18). In the first and second embodiments, the elastomeric member (26) is secured between a cuff (22) which fits around the outlet tip (14) and an end cap (24) which abuts the distal end of the piston (18). When the cuff (22) is in place around the outlet tip (14) and the end cover (24) abuts the distal end of the piston (18), with the piston (18) in its extended position, the elastomeric member (26) will be extended along the syringe. (12), so that it exerts a pressing action against the piston (18) for displacing it into the cylinder. As the elastomeric member (26) returns to its unstretched state, it will push the plunger (18) into the syringe barrel (16). In the first embodiment, the elastomeric member (26) includes one or two elastic straps with first (52) and second (54) ends detachably attached to a cuff (22). Each strap (26) has an intermediate member attached to an end cap (24).
