This creation is a kind of related injection medicine taking mechanism,It includes pedestal and takes medicine mould group,Pedestal by Hou forward sequentially be equipped with storage space,Floor outlet and shallow storage space,The pedestal of storage space installing forms the accommodation space of the default injection of accommodating plural number,Pedestal one end is formed with the opening for being connected to outlet,Two sides that are open are bent with side plate with sliding rail for active catch Men Zushe upward,Wherein recessed eluding groove below the front edge of board of side,It is equipped in pedestal shallow storage space and takes the power device of medicine mould group and its linkage of drive,Medicine mould group is taken to be equipped with two baffle of valve system by linkage drive in one high and one low staggeredly displacement again,Two baffles respectively position what opening and accommodation space and between be formed with spacing,The default injection of plural number is thereby allowed to be separated one by one again by two baffles by outlet drug,To avoid multiple default injections simultaneously drug,And active catch door will not mutually stop with baffle,Baffle can also upper and lower displacement,To reach the purpose of certain keyholed back plate injection quantity and assembling with running smoothly.本創作為有關一種針劑取藥機構，其包括基座及取藥模組，基座由後朝前依序設有收納空間、底面出口及置放空間，收納空間裝設之座體形成容置複數預設針劑之容納空間，座體一端形成有連通至出口之開口，開口二側朝上彎折有以滑軌供活動擋門組設之側板，其中一側板前端下方凹設閃避槽，基座置放空間內設有取藥模組之動力裝置及其帶動之連動裝置，取藥模組再設有受連動裝置帶動呈一高一低交錯位移之閘門裝置二擋板，二擋板分別位於開口及容納空間且之間形成有間距，藉此讓複數預設針劑被二擋板逐一隔開再由出口出藥，以避免多個預設針劑同時出藥，且活動擋門與擋板不會相互阻擋，擋板也可上下位移，以達到確實控管針劑數量及組裝與運作順利之目的。
