Lancet device with flexible cover
First Claim
Patent Images
1. A method of producing a wound in a body part of a user comprising the steps of:
- (a) the user positioning a device that includes (i) a rigid base, (ii) a stationary lancet secured to the rigid base and having a sharp region disposed substantially away from the rigid base, and (iii) a compressible lancet cover forming a cavity with the rigid base that covers the stationary lancet, the compressible lancet cover having a hole through which the stationary lancet is configured to pass; and
(b) the user compressing the compressible lancet cover with a body part onto the stationary lancet, the stationary lancet remaining stationary relative to the rigid base, until said stationary lancet protrudes through said hole in said compressible lancet cover and pierces said body part without first piercing the compressible lancet cover or anything else, producing a wound in said body part.

Abstract
The biological test kit is a device for drawing and, optionally, testing biological samples. The biological test kit is an array of lancets set in wells in a rigid base. Each lancet well is covered by a protective cover which when deformed permits the lancet to puncture a user or other patient. In one embodiment the biological test kit employs distinct covers for each lancet and in another the covers are formed from sheet material formed into blisters which cover the lancet.

6. A device, comprising:
-
(a) a rigid base; (b) a first stationary lancet secured to the rigid base and having a sharp region disposed substantially away from the rigid base; and (c) a first compressible lancet cover with a lancet hole, the first compressible lancet cover forming a first cavity with the rigid base that covers the first stationary lancet and being compressible from an unconstrained configuration in which the first stationary lancet'"'"'s sharp region does not protrude through the lancet hole to a compressed configuration in which the first stationary lancet'"'"'s sharp region protrudes through the lancet hole to the exterior of the first cavity without piercing the first compressible lancet cover or anything else inside the first cavity, wherein the first stationary lancet is stationary relative to the rigid base as the first compressible lancet cover is compressed to the compressed configuration. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A method of lancing a body part of a user, comprising:
-
(a) placing a device on a supporting surface, the device including; (i) a rigid base, (ii) a stationary lancet secured to the rigid base and having a sharp region disposed substantially away from the rigid base, and (iii) a compressible lancet cover with a lancet hole, the compressible lancet cover forming a cavity with the rigid base that covers the stationary lancet; and (b) pressing the compressible lancet cover with the body part to compress the compressible lancet cover from an unconstrained configuration in which the stationary lancet'"'"'s sharp region does not protrude through the lancet hole to a compressed configuration in which the stationary lancet'"'"'s sharp region protrudes through the lancet hole, thereby piercing the body part without piercing the compressible lancet cover or anything else inside the cavity, wherein the stationary lancet is stationary relative to the rigid base as the compressible lancet cover is pressed to the compressed configuration. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
