Abstract
Abstract A combined throw-away lancet and blood microcollection tube assembly is provided with a housing having outer dimensions for the assembly the size of a standard test tube for ease of handling and labeling, which housing incorporates a built-in lancet and blood microcollection tube. The housing includes one or more snap-open hinged covers which may be opened and closed with one hand. A further feature of the invention is provision for incorporating the used lancet in the housing for subsequent disposal to reduce contamination potential. The entire assembly may be disposed of as a single unit after use.
