An apparatus and a method for measuring a property of a blood sample is shown. The apparatus comprises a housing having an aperature a shaft(204) mounted inside the housing a testing member(505) rotatably mounted on the shaft an actuating member(501,502) coupled to the housing and configured to exert a force against the testing member and a lancet(506) for eliciting a blood sample fixedly coupled to and protruding substantially radially from the testing member and configured to co-rotate with the testing member.The apparatus is further configured such that the lancet is aligned with aperture in the housing when the testing member is in a first position.The testing member is configured, in the presence of a force exerted against the testing member by the actuator member, to translate to a second position in which the lancet is in a skin penetrating position.揭示一種用以量測血液樣本之性質的設備與方法。該設備包含:一外殼,其具有一孔口;一軸(204),其係安裝在該外殼內側;一測試構件(505),其係轉動地安裝在該軸上;一致動構件(501,502),其係與該外殼耦合並經構形對著該測試構件施以一力量;以及一用以引出一血液樣本之刺血針(506),其固定地與該測試構件耦合並大體上自該測試構件徑向地突出並經構形用以與該測試構件一同轉動。該設備係進一步經構形以致當該測試構件係位在一第一位置上時,該刺血針係與該外殼中該孔口對準。該測試構件係經構形,在藉由該致動器構件對該測試構件施力的情況下,用以轉移至一第二位置,於該第一位置,該刺血針係位在一刺穿皮膚的位置。100...血糖計101-103...輸入設備104...顯示器105...孔口106...儲存匣107...第一外殼部分108...固定蓋部分109...可移除蓋部分110...孔口
