Abstract
A handheld lancing device having anesthetic feature includes a housing removably retaining a disposable lancet. A carriage suspended within the housing by an isolation assembly may receive the lancet. A motor in mechanical communication with the lancet produces vibrations transmitted to contact surface, which vibrate a target lancing site prior to and during piercing. The target site is vibrated for a predetermined period of time before deploying the lancet. The isolation assembly permits movement of the carriage and/or lancet within the housing in one direction while limiting movement in other directions, and further dampens the vibrations of the motor from the housing held by the user. A force sensor detects force applied by the pressing of the contact surface against the skin of the patient. An indicator(s) perceivable to the user identifies when predefined positions of the lancet are reached for initiating vibration then triggering the lancet.
