The present invention is a lancing device with an automatic cocking feature. The automatically cocking lancing device utilizes a firing burton loaded with a firing button spring and a drive spring connecting the firing button to a plunger. As the user presses the firing burton and compresses the firing burton spring, the user also moves the plunger until the plunger engages a latching mechanism. The latching mechanism holds the plunger in a latched position, and, as the user continues pressing the firing button, the user compresses the drive spring connected to the plunger. Before firing, the drive spring is compressed enough such that the biasing force of the drive spring is sufficient to cause the plunger to strike and drive a lancet into the user's finger. At that point, the pressing of the firing button causes the lancing device to fife. The plunger unlatches and drives the lancet into the user's finger under the biasing force of the drive spring. At firing, the firing burton spring is compressed, and, once the user releases the firing button, the firing button spring returns the plunger and the firing button to the cocked position under the biasing force of the firing burton spring.

Disposable lancet cap

The removal of excess fluid from a test strip should be performed in a consistent manner to provide consistent results. To eliminate user variability introduced by manual blotting techniques, the device of the present invention wipes fluid from a test strip as the test strip is passed beneath a blade. The one-piece device is made of plastic so that it may be manufactured inexpensively and disposed of after use. The wiping device can also be integrated with an end cap, so that the wiping device can be attached to the end of an instrument, such as a lancet. To obtain a blood sample, for instance, the user inserts a test strip into the wiping device, where it is held while the blood sample is taken. The user deposits the blood sample onto the test strip and pulls the test strip through the wiping device. The blade removes a portion of the blood sample to provide a consistent wiping action which is not influenced by user variability. Alternative embodiments of the wiping device include apertures for viewing the test strip after wiping and colors adjacent the apertures for comparing the color of a reagent pad on the test strip after interaction with the body fluid.

Device for wiping a reagent strip

A lancet assembly includes a reusable base unit that defines a handle for a lancet assembly and houses a biasing mechanism for driving a lancet into the finger of a user. The base unit includes a spring biased hammer that once cocked, can be released to drive a lancet. A lancet is included in a disposable end cap that may be releasible attached to one end of the base unit. The end cap includes integral resilience spring fingers that maintain the lancet completely within the end cap before and after use, and functions to return the lancet after engagement of the lancet and hammer. The end cap can be rotated to orient the end cap relative to user's finger to control the depth of penetration of the lancet into the user's finger.
