    Abstract: A method of controlling lancing speed of a lancet structure of a portable handheld medical diagnostic device (10) includes providing an elongated lancet structure (24; 406; 432; 450; 506; 606) having a skin piercing end (90; 408; 434; 462; 508; 608) and a blood transport portion (92; 464; 510; 610) adjacent the skin piercing end (90; 408; 434; 462; 508; 608). The skin piercing end (90; 408; 434; 462; 508; 608) when displaced makes an incision at a skin site to produce an amount of bodily fluid from the skin site and in which the blood transport portion (92; 464; 510; 610) transports the amount of bodily fluid away from the skin site for use by a measurement system (32) in making a physiological measurement. A spring-driven motor assembly (144) is operatively connected to the lancet structure (24; 406; 432; 450; 506; 606). The spring-driven motor assembly (144) displaces the lancet structure (24; 406; 432; 450; 506; 606) toward the skin site to make the incision for producing the amount of bodily fluid and retracts the lancet structure (24; 406; 432; 450; 506; 606) to carry the amount of bodily fluid away from the skin site. A speed control mechanism (36) is engaged with the spring-driven motor assembly (144) as the spring-driven motor assembly(144) retracts the lancet structure (24; 406; 432; 450; 506; 606) thereby decelerating the lancet structure (24; 406; 432; 450; 506; 606) as the lancet structure (24; 406; 432; 450; 506; 606) is retracted away from the skin site.

    Abstract translation: 一种控制便携式手持式医疗诊断装置的穿刺结构的切开速度的方法包括提供具有皮肤穿刺端部的细长的柳叶刀结构和邻近皮肤穿刺端部的血液输送部分。 移位时的皮肤穿刺端在皮肤部位进行切口以从皮肤部位产生一定量的体液，并且其中血液输送部分将体液的量从皮肤部位输送出去，以供测量系统使用 生理测量。 弹簧驱动的马达组件可操作地连接到刺血针结构。 弹簧驱动的马达组件将柳叶刀结构移动到皮肤部位，以形成用于产生体液量的切口，并使柳叶刀结构缩回以将体液的数量远离皮肤引导。 当弹簧驱动的马达组件缩回柳叶刀结构，从而当柳叶刀结构从皮肤部位缩回时使柳叶刀结构减速，速度控制机构与弹簧驱动的马达组件接合。
