Definitions
- a rapid adaptation of the cross channels to the delivery of different injection media can be achieved by the training according to claim 14.
- the configuration according to claim 35 further enables the pressure of the injection medium exerted on the truncated cone leads to a further narrowing of the opening through the truncated cone, so that refilling of the injection device after a single use is reliably prevented even at high pressures
- FIG. 1 shows an injection device designed according to the invention in a side view and a simplified, schematic illustration
- a plurality of projections 38 projecting over an inner surface 37. These projections 38 project in the direction of the longitudinal axis 26 over the surface 39 arranged in a diameter 39 37 before.
- a height 40 of these extensions 38 is dimensioned such that a distance between the extensions 38 lying opposite in the radial direction is greater than the diameter 24 of the ball 22.
- the ball 22 is also approximately centered in the receiving space 19, and At the same time, the flow channels 41 formed between the extensions 38 allow the injection medium 33 to pass properly past the ball 22.
- the injection medium 33 then comes on due to the negative pressure generated by the piston 4 the piston 4 facing the rear of the Spe ⁇ organs 23 or the ball 22 through the 12 or the piercing opening 11 is sucked into the interior 3 of the syringe barrel 2

Abstract
Seringue à usage unique (1) comprenant un cylindre (2), une aiguille (6) et un piston (4) coulissant logé dans l'espace intérieur du cylindre (2). Ce piston est relié cinématiquement à une tige (5) partant du piston dans le sens opposé à l'aiguille (6). Dans l'espace intérieur (3) du cylindre (2), un système de blocage (7) est disposé entre le piston (4) et l'aiguille (6) avec un organe de blocage (23), retenu dans une pièce de boîtier cylindrique par le biais d'un élément de retenue (17) de préférence élastiquement déformable, dans une chambre de logement (18). L'élément de retenue (17) est logé à une certaine distance (73) d'un côté frontal d'un canal d'admission (42), qui lui est opposé. Cette distance (73) est supérieure à une longueur parallèle au sens longitudinal de la seringue (1) ou à un diamètre (24) de l'organe de blocage (23). Le boîtier de logement (8) cylindrique est divisé par l'élément de retenue (17) en une chambre de logement (18) et un espace de logement (19) pour l'organe de blocage (23). La chambre de logement (18) opposée au piston (4) est fermée par une paroi frontale (9) du boîtier de logement (8) dont le prolongement cylindrique (10) s'appuie par une surface externe (56) sur la surface interne (57) du cylindre (2). Le logement (14) est disposé dans le creux (13) du boîtier de logement. L'espace de logement (19) est conçu de manière à être ouvert dans le sens de l'aiguille (6) ou du canal d'admission (42) menant à l'aiguille (6). L'organe de blocage (23) est logé entre l'élément de retenue (17) et la paroi frontale (9) du boîtier de logement (8).
