  Aiguille tubulaire -pour injections. 



   , L'invention concerne les aiguilles tabulaires pour injections, dont l'extrémité est biseautée pour former la pointe de l'aiguilla. 



   Tel qu'on le fait 'actuellement, le biseau de ces aiguilles présente, outre un tranchant extérieur au bord avant- un tranchant intérieur au bord arrière. Lorsque, pour   prle-   ver d'une fiole le liquide à   in j ecter,   on perce au moyen de      l'aiguille le bouchon de caoutchouc ou matière semblable qui .la ferme hermétiquement, le tranchant extérieur du bord avant du biseau découpe dans le bouchon une petite fente en arc-de- HM. 2/.

 cercle et l'aisuille écarte nQrmaleuien'1n"laHL'UVtte' formée par -La fente.

   Cependant, selon l'inclinaison de   l'aiguille,   il 'peut arri- ver que le tranchant du bord arrière du biseau coupe   cotto   languet te et la partie détachée risque d'obturer l'aiguille ou même de passer dans le liquide à injecter. 



   De même lorsqu'une aiguille pénètre la peau, elle peut en entraîner une parcelle à l'intérieur des tissus. 



   La présente invention évite ce risque. 



   A cet effet, le bord arrière du biseau de l'extrémité de l'aiguille est émoussé pour le rendre non tranchant, 'par exemple en équarrissant le biseau au bord arrière, ou en l'arrondissant. 



   Le dessin annexé représente à titre d'exemple deux for- mes d'exécution. 



   Les Figs. 1 et 2 sont des vues de l'extrémité d'une ai- guille courante, la Fig. 1 en coupe axiale et la Fig.2 en vue en plan; les Figs. 3 et   4   sont des vues en coupe axiale et en      plan d'une aiguille modifiée suivant l'invention. 



   L'extrémité d'une aiguille tubulaire 1 se termine par un biseau 2 formant un bord tranchant avant 3 à l'extérieur et un bord tranchant arrière 4 à l'intérieur du biseau. 



   Suivant   l'invention,   le bord arrière   4   est émoussé afin de le rendre non tranchant et d'éviter ainsi qu'il puisse découper la   matière   du bouchon de la fiole ou la peau comme à l'emporte- pièce et en détacher une parcelle dont la pénétration dans l'ai- guille peut avoir des conséquences   nuisibles.   



   Les Figs 3 et 4 montrent à titre d'exemple le bord ar- rière 5 du biseau équarri pour l'émousser et empêcher cet effet d'emporte-pièce. Dans le même but, le bord 5 peut aussi être arrondi.. 



   Bien entendu, l'invention n'est pas   limites   à la   forme   d'exécution qui a été décrite et représentée à titre   d'exemple, et   on ne sortirait pas de son cadre en y apportant des modifications.

  Tubular needle -for injections.



   The invention relates to tabular injection needles, the end of which is bevelled to form the point of the needle.



   As presently done, the bevel of these needles has, in addition to an outer cutting edge at the leading edge, an inner cutting edge at the trailing edge. When, in order to withdraw the liquid to be injected from a vial, the stopper of rubber or similar material is pierced by means of the needle which closes it hermetically, the outer edge of the front edge of the bevel cut in the stopper a small arched slit of HM. 2 /.

 circle and the gap separates nQrmaleuien'1n "laHL'UVtte 'formed by -The slit.

   However, depending on the inclination of the needle, it may happen that the sharp edge of the rear edge of the bevel cuts off the tongue and the detached portion may block the needle or even pass into the liquid to be injected.



   Likewise, when a needle penetrates the skin, it can entrain a piece of it inside the tissues.



   The present invention avoids this risk.



   For this purpose, the trailing edge of the bevel of the end of the needle is blunt to make it blunt, for example by squaring the bevel at the trailing edge, or by rounding it.



   The appended drawing shows two embodiments by way of example.



   Figs. 1 and 2 are views of the end of a running needle, FIG. 1 in axial section and FIG. 2 in plan view; Figs. 3 and 4 are views in axial section and in plan of a modified needle according to the invention.



   The end of a tubular needle 1 ends in a bevel 2 forming a leading cutting edge 3 on the outside and a rear cutting edge 4 on the inside of the bevel.



   According to the invention, the rear edge 4 is blunt in order to make it blunt and thus prevent it from being able to cut the material of the stopper of the vial or the skin as with a cookie cutter and to detach a portion thereof. penetration into the needle can have harmful consequences.



   Figs 3 and 4 show by way of example the rear edge 5 of the bevel squared to dull it and prevent this punch effect. For the same purpose, the edge 5 can also be rounded.



   Of course, the invention is not limited to the embodiment which has been described and shown by way of example, and one would not depart from its scope by making modifications thereto.
