In order to protect a phlebotomist or technician from contact with a contaminated blood sample, it has become conventional to draw these samples in equipment designed for single use followed by strict throw away procedures. In recent years, many collection assemblies have been disclosed for drawing, transporting and analyzing these small samples. In modern medical practice, a variety of chemical and hematological diagnostic procedures are carried out on very small quantities of blood. This invention relates to blood microcollection assemblies, and more particularly relates to a microcollection assembly which is compatible with analytical instrumentation. An adapter for a microcollection container assembly comprising: a) a sleeve having a bottom wall and a side wall defining an open top end and an interior volume within said sleeve b) a shelf perpendicular to and integral with said side wall, said shelf dividing said sleeve into an upper segment and a lower segment c) a tubular body integral with and projecting upwardly from said shelf d) a plurality of rounded protuberances integral with the outside wall of said tubular body for forming an interference fit with the inside wall of a skirt of a microcollection container and e) a longitudinal rib on said side wall for forming an interference fit with an outside wall of a microcollection container. The adapter of claim 1 wherein said means is a shelf, a disc or a rim.ħ. The assembly of claim 4 wherein said assembly has an external diameter of 13 or 16 mm and a length of 75 or 100 mm.Ħ. An assembly for taking a blood sample comprising: a) the adapter of claim 1 b) a blood microcollection container immobilized in said upper portion and c) a cap for said container.ĥ. The adapter of claim 1 further comprising a longitudinal rib on said side wall for forming an interference fit with an outside wall of a microcollection container.Ĥ. The adapter of claim 1 wherein said lower segment is textured.ģ. An adapter for a microcollection container comprising: a) a sleeve having a bottom wall and a side wall, said side wall defining an open top end and an interior volume within said sleeve b) means integral with said side wall for dividing said sleeve into upper and lower segments defining upper and lower portions respectively of said interior volume c) a tubular body integral with and projecting perpendicularly upward from said means for dividing and d) a plurality of rounded protuberances integral with the outside wall of said tubular body for forming an interference fit with the inside wall of a skirt of a microcollection container.Ģ.
