Body fluid sampling device
First Claim
Patent Images
1. A sampling device for sampling a bodily fluid through an incision in a skin surface, comprising:
- a housing; and
a stimulator member attached to the housing, the stimulator member being adapted to contact the skin surface around the incision and express a drop of the bodily fluid from the incision, the stimulator member defining an interior opening having a dimension of at least 6.0 mm to minimize smearing of the drop by contact between the drop and the stimulator member.

Abstract
Body fluid is sampled from a skin incision by placing a ring against the skin and repeatedly applying an elastic pressing force to the ring, whereby a stimulator surface of the ring depresses a ring of skin and body tissue in surrounding relationship to the incision to force body fluid from the incision. The stimulator surface is inclined at an angle of 10 to 65 degrees; a width of the stimulator surface is from 5 mm to 20 mm, and an inner diameter of the stimulator surface is no less than 6.0 mm.

39. A method of obtaining a body fluid sample, comprising:
-
providing a device including a housing, a lancing device movable relative to the housing to lance skin and a stimulator member attached to the housing to contact the skin, the stimulator member defining an interior opening having a dimension of at least 6.0 mm;
lancing the skin with the lancing device to create an opening in the skin; and
expressing fluid from the opening in the skin by pressing the stimulator member against the skin.

42. A method of obtaining a bodily fluid sample, comprising:
-
providing a device including a housing, a lancing device movable relative to the housing to lance skin, a stimulator member attached to the housing to contact the skin and an outer member surrounding the stimulator member;
forming an incision in the skin with the lancing device;
contacting the skin with the outer member;
pressing the stimulator member against the skin to express bodily fluid from the incision;
relieving pressure applied by the stimulator member against the skin to allow fresh bodily fluid to flow toward the opening in the skin, and maintaining contact between the outer member and the skin during said relieving pressure.
