DEVICE FOR INJECTING A DRUG

A device for injecting a medicament is provided. The device has a housing with a container within which the medicament can be contained. The container has a needle and a stopper at its proximal end. The device includes a plunger that is engageable at one end with a stopper. At the opposite end, the plunger may engage the first resilient member to move the stopper within the container to inject medicament from the container. The device includes a collar having a distal end that engages and causes rotation of the carriage and a proximal end that engages a second resilient member. The second resilient member may be engaged with a skin sensor having a distal end and a proximal end. At the proximal end, a skin sensor may contact the injection site. The housing has a cap that can reduce or prevent movement of the skin sensor. 提供了一种用于注射药物的装置。该装置具有壳体，壳体内具有可以容纳药物的容器。容器在其近端具有针头和塞子。该装置包括柱塞，其在一端可接合塞子。在相对端，柱塞可接合第一弹性构件以使塞子在容器内移动以从容器注射药物。该装置包括具有远端和近端的套环，远端与滑架接合并引起其旋转，而近端与第二弹性构件接合。第二弹性构件可以与具有远端和近端的皮肤传感器接合。在近端，皮肤传感器可以接触注射部位。壳
