摘要:
La seringue de sécurité comporte un corps de seringue présentant un cylindre (1) et un piston présentant un joint (15), dans laquelle le cylindre comporte une partie intermédiaire (4), une paroi frontale (1a) comportant une zone de rupture (6), et dans laquelle la partie distale du piston comporte une première formation d'accouplement axial coopérant avec une seconde formation d'accouplement axial formant ensemble un accouplement axial irréversible entre le piston et la partie intermédiaire (4) du cylindre (1), cette partie distale du piston comportant en outre une formation d'entraînement en rotation (16,17). Cette seringue se distingue par le fait que le corps de seringue et le piston sont chacun venus d'une seule pièce de fabrication; que l'extrémité arrière du cylindre (1) comporte une portion conique (3) comportant des fentes longitudinales (8) délimitant au moins une portion de paroi (9) de cette portion conique (3); et par le fait que la face interne de ces portions de paroi (9) comporte d'une part une rainure de guidage longitudinale (10) coopérant avec une arête (19) de la tige (13) du piston et d'autre part au moins une nervure (11) longitudinale présentant une rampe se terminant par une butée (11a) empêchant le retrait du piston hors du cylindre.

The present invention relates to drive mechanisms suitable for use in drug delivery devices (1), in particular pen-type injectors, wherein a number of pre-set doses of medicinal product can be administered. In particular, the present invention relates to such drug delivery devices where a user may activate the drug delivery device.
摘要:
A dosage delivery device, for example a syringe type device, having a housing (2) defining a reservoir (4); a plunger (6) within the reservoir and movable to decrease the volume of the reservoir so as to discharge material in the reservoir via a discharge opening; and an operating mechanism for the plunger, wherein a closure member (12) seals the discharge opening, and is coupled to the plunger operating mechanism such that it exposes the opening when the mechanism is engaged. In this way, a single movement to prime the mechanism also removes the closure.
摘要:
A positive displacement flush syringe includes a barrel having a chamber for retaining fluid and an elongate tip extending distally therefrom having a passageway therethrough in fluid communication with the chamber. A plunger having a stopper which is slidably positioned in said chamber for driving fluid out of the chamber by movement of the stopper relative to the barrel is provided. Further, structure is provided to move fluid distally in the passageway after fluid has been delivered from the chamber and the stopper is in contact with the distal wall of the chamber.
摘要:
The invention relates to a device for the dosed administration of an injectable product, comprising a housing (1,10) provided with a reservoir (2) for the product, a piston (3) which displaces the product, which is contained in the reservoir (2) to the reservoir outlet (4) when displacement occurs in a direction of advancement, a drive mechanism (6) which can be displaced along an axis of displacement (V) in a direction of advancement until a proximal end position and in the opposite direction until a distal end position, a driven element (5) which is blocked against displacement counter to the direction of advancement and is driven by the drive mechanism (6) when a displacement of the drive mechanism (6) occurs in the direction of advancement and the piston (3) is pushed in the direction of advancement, whereby said driven element (5) is embodied as a circular threaded rod in the cross-section thereof.
