Apparatus for eliciting a blood sample comprises: a housing a shaft (204) mounted within the housing an aperture (105) in the housing, the aperture being configured to receive a part of a user a member (208, 209, 210) rotatably mounted on the shaft a lancet (309, 506) protruding from one position at an edge of the member, and a blood collection part located at a second, different position at the edge of the member. The apparatus is configured such that: when the member is in a first rotational position the lancet is shielded by the housing, when the member is in a second rotational position the lancet is operable to lance the part of the user received at the aperture, and when the member is in a third rotational position the blood collection part is presented such as to receive blood from the part of the user received at the aperture.抽出血液樣本之設備係包含:一殼體;一軸(204),其安裝於殼體內;一開孔(105),其位於殼體中,該開孔係組構為接收一使用者的一部份;一構件(208,209,210),其可旋轉地安裝於軸上;一刀針(309,506),其從位於構件的一邊緣之一位置突出,及一血液採集部份,其位於構件邊緣之一不同的第二位置。該設備係組構為使得:當構件位於一第一旋轉位置中時,刀針被殼體所屏蔽,當構件位於一第二旋轉位置中時,刀針可操作以戳刺在開孔處所接收之使用者部份,且當構件位於一第三旋轉位置中時,血液採集部份可從開孔處所接收的使用者部份接收血液。100...血糖計(BGM)101...(第一)輸入部,輸入裝置102...(第二)輸入部,輸入裝置103...(第三)輸入部,輸入裝置104...顯示器105...開孔106...匣107...(第一)殼體部份108...固定式蓋部份109...可移除式蓋部份110...長形開孔
