Title
(DE) VORRICHTUNG ZUM AUSGEBEN VON FLÜSSIGKEIT IN ABGETEILTEN MENGEN

Abstract
(DE)
Die Erfindung betrifft eine Vorrichtung (V) zum Ausgeben von Flüssigkeit (2) in abgeteilten Mengen (2') aus einem Vorratsraum (3), vorzugsweise in Form einer Kartusche (K), über ein Ausgabemundstück (4), vorzugsweise in Gestalt einer vorgesteckten Injektionsnadel (5), und bezweckt die Aufbringung exakt reproduzierbarer Mengen aus einer Vorratsmenge heraus und deren sichere Applizierung. Erreicht ist das durch einen die abgeteilte Menge (2') aus dem Vorratsraum (3) übernehmenden Zwischenspeicher (17), dem ein Ausgabekolben (19) zugeordnet ist mit einem Durchtrittskanal (18) zum Füllen des Zwischenspeichers (17).
(EN)
The invention concerns a device (V) for dispensing discrete doses (2') of a liquid (2) from a reservoir (3), preferably in the form of a replaceable cartridge (K), through a dispensing nozzle (4), preferably in the form of a hypodermic needle (5) mounted on the cartridge. The device is designed to enable exactly reproducible doses to be dispensed from the reservoir and administered reliably. This is achieved by use of an intermediate reservoir (17) into which the dose (2') passes after being dispensed from the main reservoir (3), the intermediate reservoir (17) working in conjuction with a discharge plunger (19) which has a channel (18) passing through it to allow the intermediate reservoir (17) to be filled.
(FR)
L'invention concerne un dispositif (V) pour la distribution de liquide (2) en quantités divisées (2') à partir d'un réservoir (3), de préférence sous la forme d'une cartouche (K), par l'intermédiaire d'un ajutage de distribution (4), de préférence sous la forme d'une aiguille hypodermique (5) montée sur la cartouche. L'invention a pour but de permettre que des quantités exactement reproductibles soient distribuées à partir du réservoir et soient administrées de façon sûre. Ce but est atteint grâce au fait qu'il est prévu un réservoir intermédiaire (17) recueillant les quantités divisées (2') provenant du réservoir principal (3), et auquel est associé un piston de décharge (19) présentant un conduit traversant (18) pour le remplissage du réservoir intermédiaire (17).
