Patent ID: 7169116

Claim:
A method for actuating a bodily fluid extraction device, the method comprising: providing a bodily fluid extraction device that includes an automated firing mechanism and an actuation system, the actuation system having: a detector cap with a proximal surface; at least one vibration sensor connected to the detector cap; and a signal processing unit in communication with each of the at least one vibration sensor, wherein the signal processing unit is configured to receive an output signal from each of the at least one vibration sensor, to analyse the received output signal, and to send an actuation signal to the automated firing mechanism device based on the analysis of the received output signal. urging the bodily fluid extraction device towards a target site; receiving an output signal from each of the at least one vibration sensor by the signal processing unit; employing the signal processing unit to analyse the output signal received from each of the at least one vibration sensor; sending an actuation signal to the automated firing mechanism from the signal processing unit based on the analysis.
