ジェット式注射装置のための係止機構
Document Type and Number:
Japanese Patent JP4236843
Kind Code:
B2
Abstract:
A needle assisted jet injector having a locking mechanism for reducing the likelihood of inadvertent contact with the needle and deterring intentional reuse of the needle are disclosed. Upon activation of the force generating source, a portion of the needle extends past the nozzle assembly and penetrates the outer layer of skin to deliver the medicament via jet injection to a deeper region. After activation, the needle retracts back into the nozzle assembly. The locking mechanism includes a needle holder and a locking ring, which mate upon activation of the injector and prevent reignition.
