Patent

CA 2395409

The present needle cover assembly (12) includes a first, larger half or arm (16) and an opposite unequal second, smaller half or arm with an arc-shaped inner shell such that the first half or arm encloses the arc-shaped inner shell of the second half or arm of the needle cover assembly. Additionally, the lateral side members of the first, large arm (16) are fabricated so as to incorporate a 45 degree angle cut (17), extending from the beginning of each lateral side member up to the lower one-third region of each lateral side member, the 45 degree angle cut will allow the larger and smaller arms of the needle cover to securely interlock when the assembly is placed in the closed position. A rotatable collar (20), surrounding the frustum-shaped base member (112), possesses a plurality of ridges (150) on its external surface (150) which allows the collar to easily rotate. When the collar is rotated approximately 90 degrees, the two halves or arms of the cover member are split apart so that the two halves or arms of the needle cover are away from each other, exposing the needle (6) so that it can be used for an injection of medicine.

L'invention concerne un ensemble enveloppe d'aiguille (2) qui comprend une première moitié ou un premier bras (16) et une seconde moitié ou un second bras opposé inégal de plus petite taille associé à une coque intérieure en arc, de façon que le premier bras renferme la coque intérieure en arc du second bras de l'ensemble enveloppe d'aiguille. Les éléments latéraux du premier bras de taille plus importante (16) sont fabriqués de façon à intégrer un angle d'intersection de 45 degrés (17), et s'étendent du début de chaque élément latéral jusqu'au tiers inférieur de chaque élément latéral. L'angle d'intersection de 45 degrés permettra aux bras, grand et petit, de l'ensemble enveloppe d'aiguille de s'interverrouiller fermement lorsque l'ensemble est placé en position fermée. Un collier rotatif (20), entourant l'élément de base en forme de tronc (112), comprend plusieurs arêtes (115) sur sa surface extérieure (150) qui permettent au collier de pivoter facilement. Lorsque le collier est tourné à 90 degrés, les deux bras de l'élément d'enveloppe sont séparés et espacés, exposant ainsi l'aiguille qui peut alors être utilisée pour injecter des médicaments.
