    • A cap for use with a dermal tissue lancing device (that includes a housing and a lancet movable with respect to the housing) includes a proximal end for engaging with the housing, a distal end for engaging with dermal tissue and an opening for a portion of the lancet to pass through. The distal end of the cap includes portions for engaging dermal tissue. These portions are resiliently deformable such that, when the cap contacts and is urged towards dermal tissue, the portions deform resiliently, engaging the dermal tissue and approaching theretogether. A process for the collection of a fluid sample (e.g., blood) from dermal tissue includes providing a dermal tissue lancing device with a housing, a cap and a lancet that is moveable with respect to the housing and the cap. The cap includes a proximal end for engaging with the housing, a distal end for engaging with dermal tissue, and an opening for a portion of the lancet to pass through. The distal end of the cap includes resiliently deformable portions for engaging dermal tissue. Next, the cap is contacted with the dermal tissue (e.g., dermal tissue of a fingertip, limb, or abdomen) such that the portions engage the dermal tissue. Subsequently, the cap is urged towards the dermal tissue such that at least first and second portions deform resiliently and approach theretogether to create a bulge in the dermal tissue. The bulge is then lanced to create a puncture from which a fluid sample is collected.
    • 用于真皮组织穿刺装置(包括壳体和相对于壳体可移动的刺血针)的帽包括用于与壳体接合的近端,用于与真皮组织接合的远端和用于部分 刺血针通过。 帽的远端包括用于接合皮肤组织的部分。 这些部分是可弹性变形的,使得当帽接触并被推向真皮组织时,这些部分弹性变形,与真皮组织接合并且一起接近。 用于从真皮组织收集流体样品(例如血液)的方法包括提供真皮组织切割装置,其具有可相对于壳体和盖移动的壳体,帽和刺血针。 盖包括用于与壳体接合的近端,用于与真皮组织接合的远端和用于刺血针的一部分通过的开口。 盖的远端包括用于接合皮肤组织的弹性变形部分。 接下来,将盖与真皮组织(例如,指尖,肢体或腹部的真皮组织)接触,使得这些部分接合皮肤组织。 随后,将帽推向真皮组织,使得至少第一和第二部分弹性变形并且一起接近以在真皮组织中产生凸起。 然后将凸起切开以产生从中收集流体样品的穿刺。
