摘要:
A lancing device is formed of a main body having a built-in firing unit and a replaceable lancet for blood sampling. The main body includes a detachable front shell mounted to a front end thereof. The front shell is formed of a housing and a positioning member sleeved into the housing for movably receiving the lancet. The positioning member further includes at least one shock-absorption layer arranged around an imaginary central axis of the lancet and made of a soft material. When the lancet is hit by the firing unit to move forward and returns instantaneously, while reaching a predetermined stroke, and a front end of the lancet generates energy of radial vibration due to collision or suddenly return. The at least one shock-absorption layer absorbs most or all of the energy of the radial vibration, so the vibration suffered by the testee becomes greatly less to the make the testee feel hardly painful.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,其中,該定位件的內壁面設有由軟質材料所構成的吸震層。因此,當取血針被擊發單元擊發而移動時,取血針移動達到預定行程時將會快速反轉其移動方向,此時取血針前端因碰撞而產生的徑向震動能量將大部分或全部由吸震層吸收,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。20‧‧‧本體22‧‧‧前蓋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、41‧‧‧吸震層
