Abstract
The application discloses a lancet device (100) that includes a base (102) that supports a lancet (104) and a cover (106). The cover can move controllably from an un-depressed position to a depressed position when a predetermined force is applied. The cover can provide access to the lancet in the depressed position.
Claims14
A lancet device comprising:
- (a) a base that includes a support surface;
- (b) a lancet supported by the base and extending away from the support surface at an angle of approximately 90°;
- (c) a cover that includes (i) a peripheral edge along which the cover is connected to the base, (ii) a cover region configured to cover the lancet when the cover is in an un-depressed position, the cover region having a cover region geometry comprising a cover region wall thickness, (iii) a lancet aperture through which the lancet is configured to protrude when the cover is in a depressed position, and (iv) a peripheral hinge near the peripheral edge, the peripheral hinge having a peripheral hinge geometry comprising a peripheral hinge wall thickness that is less than ¾ the cover region wall thickness to facilitate controlled movement of the cover from the un-depressed position to the depressed position upon application of a predetermined depression force.
The lancet device of claim 8, wherein the cap is configured to act as a sterile barrier when in the capped position to isolate the lancet from contaminants.
13-25. (canceled)
A method of collecting a biological sample, comprising:
- (a) providing a lancet device that includes (i) a base with a support surface, (ii) a lancet supported by the base and extending away from the support surface at an angle of approximately 90°, and (iii) a cover with (A) a peripheral edge along which the cover is connected to the base, (B) a cover region with a cover region geometry comprising a cover region wall thickness, (C) a lancet aperture, and (D) a peripheral hinge near the peripheral edge, the peripheral hinge having a peripheral hinge geometry comprising a peripheral hinge wall thickness that is less than ¾ the cover region wall thickness;
- (b) applying a predetermined force to the cover region, thereby moving the cover from an un-depressed position in which the cover region covers the lancet to a depressed position in which the lancet protrudes through the lancet aperture and exposes biological fluid;
- and
- (c) collecting a quantity of the biological fluid as the biological sample.
