摘要:
Syringe consists of a housing containing a cylindrical reservoir for active fluid to be injected, held between two movable plugs, and a holder (37) with at least two peripheral injection ducts (38) and a blind cavity (31) with a depth that permits separation of inlets (39) from peripheral ducts when downstream plug is in contact with bottom of cavity following operation of a drive that moves the two plugs and the fluid between them. The syringe consists of a housing containing a cylindrical reservoir for the active fluid to be injected, held between two movable plugs, and a holder (37) with at least two peripheral injection ducts (38) and a blind cavity (31) with a depth that permits the separation of inlets (39) from the peripheral ducts when the downstream plug is in contact with the bottom of the cavity following the operation of a drive that moves the two plugs and the fluid between them. Each of the inlets (39) has a recess round an injection duct that is connected by a radial channel to the central cavity. The diameter of each recess is between 1.1 and 1.5 times the diameter of the injection duct, and its depth is 0.5 - 0.6 of the duct's diameter.Oppfinnelsen angår området engangs nåleløse sprøyter som benyttes for å injisere flytende, aktive substanser. Sprøyten omfatter et reservoar som er lukket av forskyvbare plugger som innestenger væsken. Reservoaret er opprinnelig isolert fra en injektorbeholder (37) som er utformet med i det minste to injeksjonskanaler (38) anordnet utenfor beholderen (37). Beholderen (37) omgir en blindboring (31) som inneholder pluggen som befinner seg nedstrøms, slik at de optimaliserte innløpene (39) til kanalene er uten hindringer Den flaten på beholderen (37) som befinner seg oppstrøms omfatter en flerfliks-tetning (34) anordnet parallelt med og så nær kantene til boringen (31) og innløpene (39) som mulig. Formålet med oppfinnelsen er å komme frem til en injektorbeholder (37) som er optimalisert mht. utstrømning og dennes motstan
