DEVICE FOR OPENING GLASS AMPOULES

摘要

This invention relates to an ampoule opening device (1) for the opening of glass ampoules (100) of the type used in particular in the pharmaceutical field for injection substances. The device according to this invention allows opening, by rupture of the neck of the ampoule, glass ampoules of different capacities (and therefore of sizes), by generating a non irregular rupture edge and therefore minimizing the creation of glass fragments that may fall into the substance contained within the ampoule. Moreover, the device object of this invention allows avoiding contact of the user's fingers with the neck and the cap of the ampoule, thereby preventing any risk of accidental injuries. The device object of this invention allows obtaining excellent results in terms of quality of the rupture edge of the ampoule neck and of repeating the result obtained thanks to the fact that the device allows to apply to the ampoule a constant rupture bending moment for ampoules of the same type.

主权项

1. An ampoule opening device comprising:
a main body configured to be grasped by a user, said main body comprising at least a partial opening at an end, a stop element and a guide element to position a cap of an ampoule, said stop element protruding from said main body; and position and grasp element hinged to said main body to position and grasp a body of said ampoule which is at least partly inserted into the at least partial opening of said main body and an elastic element which acts between said position and grasp element and said main body, said position and grasp element being movable between a first resting position wherein said elastic element pushes said position and grasp element toward an outside of said main body, and a second compressed position wherein said position and grasp element is inserted within said main body to an extent allowed by deformation of said elastic element which is compressed.
