    • A lancing device includes a lancing mechanism, a floating probe and a pressure tip. The lancing mechanism includes a lancet carriage, a lancet holder slidably connected to the lancet carriage, and a lancet attached to the lancet holder. The pressure tip of the lancing device is configured for engaging a target site and creating a target site bulge. The floating probe is adapted to floatably contact the target site bulge and to operatively interact with the lance carriage to control a penetration depth of the lancet into the target site bulge. A method for lancing a target site includes providing the lancing device describe above and contacting the pressure tip of the lancing device with the target site. The pressure tip is then urged towards the target site to create a target site bulge with the floating probe of the lancing device floating on a surface of the target site bulge. Next, the target site bulge is lanced while the floating probe operatively interacts with the lance carriage to control a penetration depth of the lancet.
    • 采血装置包括采血机构,浮动探头和压力尖。 所述切断机构包括:柳叶刀托架,可与所述柳叶刀托架滑动连接的刺血针托架,以及连接于所述刺血针托架的刺血针。 穿刺装置的压力尖端被配置用于接合目标部位并创建目标部位凸起。 浮动探针适于与目标部位凸起浮动接触并且与喷枪托架可操作地相互作用以控制刺血针进入目标部位凸起的穿透深度。 用于穿刺目标部位的方法包括提供上述描述的穿刺装置,并将穿刺装置的压力尖端与目标部位接触。 然后将压力尖端朝向目标部位推动以产生目标部位隆起,其中穿刺装置的浮动探针浮在目标部位隆起物的表面上。 接下来,在浮动探针与喷枪托架可操作地相互作用以控制刺血针的穿透深度的同时,靶部位凸起被拉平。

    • A micro-needle is provided which is particularly useful for the minimally invasive sampling of a biological fluid and/or the minimally invasive delivery of a drug or other formulation across the skin. The micro-needle has a structure having a base at a proximal end and a vertex at a distal end, and an open lumen extending there through and through which fluid may be transferred. The structure defines a structural axis that intersects the lumenal axis defined by the open lumen. The point of intersection between these axes is at a point below the vertex of the micro-needle to provide a sharp apex at the distal end of the micro-needle and defines the general configuration of the distal end of the micro-needle, which may be selected or customized depending on the intended use of the microneedle. The micro-needle may be integral with a measurement device for measuring the concentration of a constituent within sampled biological fluid and/or with a fluid reservoir for containing a fluid to be delivered, and may also be used in conjunction with a remote control means. Methods of making and using the micro-needle of the present invention as well as kits comprising one or more of the micro-needles are also provided.
    • 提供了一种微针,其特别适用于生物流体的微创取样和/或通过皮肤的药物或其它制剂的微创输送。 微针具有在近端具有基部并且在远端具有顶点的结构,以及在其上延伸并且流体可被传送的开放腔。 该结构限定了与由开口腔限定的内腔轴相交的结构轴线。 这些轴之间的交点位于微针的顶点以下,在微针的远端处提供尖锐的尖端,并且限定了微针的远端的一般结构, 根据微针的预期用途进行选择或定制。 微针可以与用于测量采样的生物流体中的组分浓度和/或用于容纳要输送的流体的流体储存器的测量装置成一体,并且还可以与遥控装置结合使用。 还提供了制造和使用本发明的微针的方法以及包括一个或多个微针的试剂盒。
