摘要：
A liquid drug delivery apparatus and a drug delivery method. The apparatus is provided with an upper housing and a lower housing which are capable of relative rotation, the upper housing being internally embedded with an upper rotary component, the lower housing being internally embedded with a lower rotary component and provided with a spring. Inner walls of the upper rotary component and the lower rotary component are respectively provided with mutually matching slide surfaces, so that the lower rotary component moves away from the upper housing and compresses the spring when rotating relative to the upper rotary component along a first direction. A stopping and limiting structure is also provided, to limit the rotation range when the lower rotary component rotates relative to the upper rotary component along the first direction, in order to prevent the slide surfaces from disengaging. A guide tube moves up and down with the lower rotary component. When the lower rotary component rotates along the first direction, the guide tube moves down. When the lower rotary component rotates relative to the upper rotary component along a second direction, opposite to the first direction, the spring resets and the guide tube moves up. The liquid drug delivery apparatus is gentle during use and simple to operate, and has good user acceptance.本發明公開一種液體藥物輸送裝置，具有可相對轉動的上殼體和下殼體，上殼體內嵌有上旋轉部件，下殼體內嵌有下旋轉部件並設有彈簧，上旋轉部件和下旋轉部件內壁分別設有相互配合的滑動面，使得下旋轉部件在沿第一方向相對上旋轉部件轉動時遠離上殼體並壓縮彈簧；其特徵在於：設有止動限位元結構，在下旋轉部件沿第一方向相對上旋轉部件轉動時對轉動幅度進行限位，當下旋轉部件沿第一方向轉動時，導管下移；下旋轉部件沿與第一方向相反的第二方向相對上旋轉部件轉動時，彈簧復位且導管上移。本發明不存在對彈簧的瞬間釋放，使用過程比較溫和。
