The present application relates to an apparatus for eliciting a blood sample. The apparatus has a housing having an aperture. A shaft extends in the housing and is received through a hole in a test member. A lancet protrudes radially from the test member. The hole is configured to allow the test member to translate relative to the shaft, in the presence of a force exerted on the test member by an actuator, from a retracted position to a skin penetrating position in which the lancet is displaced towards the aperture.本申請案關於一種引出血液樣本之裝置。此裝置具有一殼體殼體,此殼體殼體具有一窗孔。一軸在殼體殼體中延伸並係經由一開孔被接收在一測試構件中。一刺針從測試構件徑向地伸出。開孔被設計成用以允許測試構件在一藉由一致動器施加在測試構件上之力量存在的情況下,相對於此軸從一收回位置平移至一肌膚穿刺位置,於其中刺針係朝向窗孔被移動。105‧‧‧窗孔203‧‧‧圓筒形部分/圓筒狀殼體殼體部/殼體204‧‧‧軸700‧‧‧圓盤構件/測試構件705‧‧‧前圓盤邊緣/前面706‧‧‧後圓盤邊緣/後邊緣707‧‧‧凹口708‧‧‧弓形邊緣709‧‧‧弓形邊緣710‧‧‧血液收集部711‧‧‧刺針711A‧‧‧末端712‧‧‧開孔713‧‧‧側面714‧‧‧側面715‧‧‧前面716‧‧‧背面717‧‧‧驅動撥爪718‧‧‧側驅動面719‧‧‧側驅動面720‧‧‧前驅動面721‧‧‧後驅動面724‧‧‧彈性構件724A‧‧‧自由端725‧‧‧凹部726‧‧‧平面
