摘要：
An injection device for delivering a medicament from a syringe contained, in use, within a housing of the device, the device being configured to move the syringe through the housing to cause insertion of a needle of the syringe into a user’s skin and to subsequently move a bung of the syringe through a syringe body to deliver medicament through the needle. The device comprises a plunger for engaging with said bung, a sleeve located around the plunger, an insertion spring biasing the sleeve relative to the housing, and a delivery spring biasing the plunger relative to the sleeve. The device further comprises a release mechanism for releasing the sleeve from the housing to commence insertion and for releasing the plunger from the sleeve, following insertion, to commence delivery of the medicament, and a velocity regulator for regulating the velocity of the plunger upon its release from the sleeve and for disengaging from the plunger during delivery, the velocity regulator comprising a screw thread associated with one of the sleeve and the plunger and one or more thread engaging members formed on the other of the sleeve and the plunger.一種用於輸送來自注射器的藥劑的注入設備，該注射器在使用過程中被包含在所述設備的殼體內部，所述設備被配置成移動注射器通過所述殼體，以使注射器的注射針插入使用者皮膚，以及隨後移動注射器的塞子通過注射器主體， 以便通過注射針來輸送藥劑。 該設備包括用於與塞子嚙合的柱塞，圍繞柱塞的套筒，相對於殼體偏置套筒的插入彈簧，以及相對於套筒偏置柱塞的輸送彈簧。 該設備進一步包括釋放機制，用於通過從殼體上釋放套筒而開始插入，並且在插入之後，通過從套筒上釋放柱塞而開始輸送藥劑，以及速度調節器，用於在從套筒上釋放柱塞的時候調節柱塞的速度以及在輸送過程中脫離柱塞， 所述速度調節器包括與套筒和柱塞中的一個相關聯的螺紋以及在套筒和柱塞中的另一個上形成的一個或多個螺紋嚙合構件。
