INSERT AND VIAL FOR THE INFUSION OF LIQUIDS

摘要

The present invention relates to an insert (40) and a vial (30) for the infusion of a liquid (80). The vial (30) comprises a hollow body (31) for storing the liquid (80), a grasp portion (38) and a head (32). The head comprises a delivery opening (33) defining an axis (X), a closing septum (34) suitable for closing the delivery opening; and at least one circumferential push surface (35) defined next to the head by a protrusion. The circumferential push surface is firmly connected to the grasp portion. The insert (40) according to the invention is suitable to delivery the liquid (80) and to receive the insertion along axis (X) of the vial. The insert comprises a main body (41) and an inner part (42). The main body comprises a lateral wall (410) and a lower delivery portion (411) defining a first lower duct (511) and a second lower duct (521). The inner part comprises an inner wall (420) and a piercing spike (421). The inner wall (420) defines a seat (422) suitable to receive the head of the vial, and comprises at least one slit (423) suitable to engage a radially inner portion (350) of the at least one circumferential push surface of the vial. The piercing spike is suitable to pierce the closing septum of the vial and defines a first upper duct (510) and a second upper duct (520). The inner part is housed inside the main body so as to be able to rotate with respect to the latter around axis (X). In particular, the inner part is able to rotate between: a fluidly open configuration A wherein the upper ducts are in fluid communication with the lower ducts; and a fluidly closed configuration (B) wherein the upper ducts are not in fluid communication with the lower ducts.
