Needle Mounting Feature for Ensuring Proper Reconstitution Sequence

摘要

In one aspect, a medical injector is provided herein having a body and an overcap releasably attached to the body configured to prevent mounting of a needle prior to mixing of components within the body. In a further aspect, a slidable collet may be provided useable to urge resilient members from an outward disrupted state inwardly to collectively define a needle mount. Advantageously, a medical injector is provided which ensures proper sequence in preparation of the device, particularly with respect to the step of allowing mounting of a medical needle to the device subsequent to preparation of the medicament to be administered.

主权项

1. A medical injector, comprising:
a body having a reservoir defined therein; a plurality of resilient members engaged with the body which are deflectable between a first state, in which the plurality of resilient members collectively define a needle mount for engaging a needle, and a second state, in which the plurality of resilient members are deflected radially outward and the needle mount is disrupted; and a slideable collet configured to urge the plurality of resilient members from the second state to the first state.
