Magnetic lancet device

摘要

Embodiments of the present invention provide magnetic lancet devices and methods for driving a lancet. For example, a magnetic lancet device may include a driving mechanism having a plurality of magnets and a lancet coupled to the driving mechanism. A magnetic interaction between the plurality of magnets is configured to drive the lancet from an engaged position to a penetrating position.

主权项

1. A device, comprising:
a guide tube that is hollow and includes a driving end and a lancet end and a longitudinal axis extending between the driving end and lancet end; a first magnet and a second magnet positioned on opposite sides along a length of the longitudinal axis of the guide tube; a third magnet positioned within the guide tube; a lancet housing coupled to an end of the third magnet disposed towards the lancet end; and a lancet attached to an end of the lancet housing disposed towards the lancet end; wherein a like pole of the first magnet and a like pole of the second magnet are configured to face one another in a repulsive interaction, and wherein a like pole of the third magnet is configured to face towards the lancet end.
