Title
(EN) AN INJECTION ASSEMBLY WITH A RETRACTABLE INJECTION NEEDLE
(FR) ENSEMBLE D'INJECTION A AIGUILLE D'INJECTION RETRACTABLE
Abstract
(EN)
An injection assembly, at least comprising a liquid container (2) with an outflow opening (11), and a piston (3) displaceable therein, a suction needle (4) with a needle fitting which is adapted to be releasably fitted on or in the outflow opening (11) of the liquid container (2), and an injection needle (6) with a needle fitting which is adapted to be permanently fixed on or in the outflow opening of the liquid container, said assembly comprising an auxiliary coupling part (10; 40; 60) which is or can be fixed in the outflow opening (11) of the liquid container (2), which, on the one hand, is or can be connected with the needle fitting of the injection needle (6), and which, on the other hand, comprises second coupling means which can be permanently coupled with the first coupling means of the piston (2) in the presence of the injection needle (6), which coupling, however, cannot take place in the presence of the suction needle (4).
(FR)
Ensemble d'injection comportant, au moins, un réservoir pour liquide (2) muni d'un orifice de sortie (11), et un piston (3) monté mobile dans ce réservoir, une aiguille d'aspiration (4) pourvue d'un raccord d'aiguille adapté pour se fixer de manière détachable sur ou dans l'orifice de sortie (11) du réservoir pour liquide (2), et une aiguille d'injection (6) pourvue d'un raccord d'aiguille adapté pour se fixer de manière permanente sur ou dans l'orifice de sortie du réservoir pour liquide. Ledit ensemble comporte un élément auxiliaire d'accouplement (10; 40; 60) qui est ou peut être fixé dans l'orifice de sortie (11) du réservoir pour liquide (2), et qui, d'une part, est ou peut être relié au raccord d'aiguille de l'aiguille d'injection (6), et d'autre part, comporte un second organe d'accouplement apte à s'accoupler de manière permanente avec le premier organe d'accouplement du piston (2) en présence de l'aiguille d'injection (6), cet accouplement ne pouvant cependant se produire en présence de l'aiguille d'aspiration (4).
