The utility model discloses a blood collection device with a shockproof structure. The blood collection device is provided with a body with a built-in trigger unit and a replaceable blood taking needle used for sampling the capillaries of human fingertips or other portions, wherein a detachable front cover is arranged at the front end of the body, formed by mutually sleeving a housing body and a positioning element, and used for slidably receiving the blood taking needle the shockproof structure is further provided and arranged between the positioning element and the housing body. Therefore, when the blood taking needle is triggered by the trigger unit to move, the front end of the blood taking needle stops moving forwards while colliding with the stop portion of the positioning element, and instantaneously reverses the moving direction thereof, at this moment, most of or all of the vibration energy in each direction, generated by collision between the front end of the blood taking needle and the positioning element is absorbed by the shockproof structure therefore, shock amplitudes suffered by users during blood collection are greatly reduced, and then the pain of the users is reduced to the lowest.一種採血裝置,具有內建擊發單元的一本體與可置換的一取血針作為人類指尖或其他部位微血管採樣之用,本體前端設有一可拆卸的前蓋,且前蓋是由一外殼體與一定位件相互套設而成,用以可滑動地容設取血針,更具有一避震結構設於定位件與外殼體之間。因此,當取血針被擊發單元擊發而移動時,取血針的前端碰撞到定位件的擋止部時會停止前進,並瞬間反轉其移動方向,此時取血針前端碰撞定位件所產生的各方向震動能量,將大部分或全部會由避震結構吸收,因而使用者採血時遭受的震幅大幅減少,進而使用者的疼痛感降到最低。10‧‧‧採血裝置20‧‧‧本體22‧‧‧身部23‧‧‧固定座24‧‧‧外殼體241‧‧‧出針口26‧‧‧定位件28‧‧‧滑動通道281‧‧‧擋止部282‧‧‧小徑部284‧‧‧錐形部286‧‧‧大徑部30‧‧‧取血針32‧‧‧針頭34‧‧‧針座341‧‧‧前端部40‧‧‧減震結構
