Adapter for connecting medical containers

Abstract

The invention relates to an adapter for connecting a medical container closed by a septum, the adapter comprising: a clamp (20) for fixing the adapter to the medical container; a needle inlet facing the outer surface of the septum; a pierceable elastomeric element (50) having a longitudinal axis within the needle inlet, said pierceable elastomeric element comprising a recess (51) having a proximal opening and an outer wall (54) in contact with the needle inlet; Connecting device to retain the elastomeric element in the needle access port. The invention also relates to an assembly comprising such an adapter and a medical container, and the use of such an adapter to prevent internal contamination of a medical container closed by a septum.

Description

technical field [0001] The present invention relates to an adapter for connection to a medical container, such as a vial containing a medicament, which allows the withdrawal of multiple doses of said medicament while maintaining sterility and its efficacy over a prolonged period of time. sex. Background technique [0002] In this application, reference is made to an injection device for use with an element or device, the distal end of which element or device must be understood as the end furthest from the user's hand and the proximal end must be understood as the end farthest from the user's hand. the nearest end of the hand. Thus, in this application, the distal direction has to be understood as the injection direction with respect to the injection device, and the proximal direction is the opposite direction, ie the direction in which the product is transferred from the vial to the injection device. [0003] Medical containers, such as vials, are commonly used to store an...

Problems solved by technology

This leads to a large amount of wasted doses and significantly increases the cost of immunization and epidemic treatment

In addition, there is a risk of contaminated product being injected into the patient due to incorrect disposal of the contaminated vial

This can lead to ineffective vaccination of populations, significant side effects and loss of confidence in immunization campaigns

[0008] In addition, if the continuous piercing of the septum of the multi-dose vial with the needle of the injection device is not performed correctly, needle damage or bending may occur

Finally, there is a risk of accidental punctures to the user because the user's fingers are in close proximity to the needle of the injection device during operation and the user needs to grasp the injection device while manipulating the multidose vial

This can lead to the discarding of unused injection sets and or multidose vials, increasing the cost of immunization campaigns or epidemic treatment
