Abstract

A lancet depth adjustment assembly structured to be used use with a lancet device of the type including a lancet disposed movably within a housing so as to pass into a piercing orientation wherein a piercing tip of the lancet protrudes from a piercing aperture defined in the housing. The lancet depth adjustment assembly includes a depth adjustment element movably secured in overlying relation to the piercing aperture of the housing and having a piercing access including one or more openings structured to permit passage of the piercing tip of the lancet therethrough. The depth adjustment element is structured to be interposed between a finger of a patient and the piercing aperture so as to define a spacing therebetween, and accordingly define a depth to which the piercing tip, which protrudes a defined amount from the housing, penetrates the body part. Furthermore, the depth adjustment element is constructed of a varying thickness so as to vary the spacing between the body part and the piercing aperture in accordance with a thickness of a portion of the depth adjustment element disposed in overlying relation to the piercing aperture at a time of operation of the lancet device.

Claims

1. For use in combination with a lancet device including a lancet disposed within a housing and structured to move into a piercing orientation wherein a piercing tip of the lancet protrudes from a piercing aperture defined in the housing, a lancet depth adjustment assembly comprising:

a depth adjustment element, said depth adjustment element secured in at least partially overlying relation to the piercing aperture of the housing;

said depth adjustment element including a piercing access structured to permit passage of the piercing tip of the lancet therethrough;

said depth adjustment element structured to define a spacing between the finger and the piercing aperture, and accordingly a depth to which the piercing tip penetrates the finger;

said depth adjustment element having an exterior surface disposed in at least partially overlying relation to the piercing aperture of the housing,

said exterior surface defining a plurality of different spacings from the piercing aperture as a result of a portion of said exterior surface that is disposed in said overlying relation to the piercing opening, and structured to maintain the finger at a corresponding one of said different spacings from the piercing aperture, and

said piercing access defining an opening at least two of said different spacings so as to permit the passage of the piercing tip therethrough when said depth adjustment element is disposed in overlying relation to the piercing aperture in at least two distinct piercing locations.

2. A lancet device comprising:

a lancet, said lancet having a piercing tip;

a housing;

said lancet movable into a piercing orientation wherein said piercing tip protrudes from a piercing aperture a predetermined uniform amount;

a depth adjustment element having an exterior surface positioned in at least partially overlying relation to the piercing aperture of the housing,

said exterior surface comprising a plurality of steps,

each of said plurality of steps defining a different spacing from said exterior surface to the piercing aperture, and accordingly a varying depth to which the piercing tip penetrates a finger disposed on said exterior surface;

a position of said plurality of steps is collectively adjustable relative to the piercing aperture; and

a guide structured to movably retain and position said depth adjustment element in overlying relation to the piercing aperture.
