Embodiment Construction

[0046] The lancet of the present invention has a shielded lancet and is simpler, more convenient and less expensive than prior art lancets. The lancet according to the invention automatically protects the lancet and can be produced inexpensively. The lancet of the present invention also minimizes the number of steps the user must follow and minimizes the number of devices the user must carry to perform blood sampling.

[0047] figure 1 A top-down illustration (top view) of an exemplary embodiment of the invention is shown. figure 1The lancet has a lancet arm extending from a body portion. The lancets are arranged on the lancet arms. The lancet may be any device capable of piercing the skin on a finger or other detection area of ​​the human body. The part of the lancet that is capable of piercing the skin is the tip of the lancet. The needles can be needles, hooks, etc., and can be made of plastic, metal, or ceramics. A protective arm also extends from the main body porti...

Abstract

An improved lancet as well as methods and devices for using the improved lancet are provided. The improved lancet comprises a body section with a lance arm and one or more protective arms extending from the body section. The lance arm has a lance with a sharp portion for piercing skin disposed on the lance arm. The sharp portion of the lance extends at an angle of about 45 to 135 degrees to the direction of extension of the lance arm from the body section. The protective arms have a protective section for shielding the sharp portion of the lance. The sharp portion of the lance is exposed fromthe protective section by application of pressure to the lance arm.

Description

technical field [0001] The present invention generally relates to systems and methods for detecting bodily fluids. In particular, the present invention relates to simple, convenient and inexpensive lancets for obtaining samples of bodily fluids for testing. The invention also relates to devices and methods for using the improved lancet. Background technique [0002] Point-of-care (point-of-care, POC) or home testing is becoming more common as the incidence of certain infectious diseases, substance abuse, or metabolic disorders increases. Analytical tests designed for use in such environments must meet heightened demands for safety, performance, simplicity, convenience and cost. In general, the state of the art in analytical chemistry has evolved to the point where such tests can achieve performance requirements in terms of accuracy, precision and assay time. However, there remains an ongoing need to further improve the safety, ease, convenience, and cost of POC assays. ...
