Patent ID: 7481776

Claim:
A skin penetrating system, comprising: a drive force generator; a disposable housing member; a plurality of penetrating members positioned in the disposable housing member each penetrating member being coupled to the drive force generator; a plurality of analyte detecting members each associated with a penetrating member and positioned in the disposable housing member, each analyte detecting member positioned in a sample chamber that has an opening for transport of a body fluid into the sample chamber, each analyte detecting member being configured to determine a concentration of an analyte in a body fluid using a sample of a body fluid disposed in the sample chamber; each penetrating member being associated with the sample chamber, each penetrating member and its associated sample chamber having a combined occupied volume of no more than about 5.0 cm 3 ; at least one seal positioned at an exterior of the disposable housing; an electrical user interface coupled to a processor, the electrical user interface having at least one user output selected from, penetration depth of a penetrating member, velocity of a penetrating member, velocity of a penetrating member in or out of target tissue and a dwell time of a penetrating member in the target tissue, wherein a time and position of tissue contact and depth of penetration is determined by the processor by knowing, (i) a distance of a penetrating member tip from a target tissue, (ii) acceleration and displacement of the penetrating member and (iii) a start position of the penetrating member.
