Device for standard preparation of urinary sediment for urine analysis (Mono System)

摘要

A System for use in sample processing for urine sediment analysis that is composed of a main tube and a thinner inner tube (without capillarity), which is attached to the wall of the main tube and has the volume equal to one twelfth of the main tube. Near an upper end of both tubes, a small connected aperture on each tube allows evacuation of air from the inner tube when urine enters this tube from an open end. After urine centrifugation, the small opening is closed by operator's finger and the supernatant is poured out from the main tube. This allows retention of the urine in the inner tube, which will be added to the sediment after unblocking of the aperture.

1. A Mono System for urine sediment analysis comprising: a main tube comprising a closed distal end and an open proximal end, having a specific volume; an inner tube, located inside said main tube and comprises a connecting point with said main tube; wherein said inner tube comprises an open proximal end and an open distal end, where said open distal end is located near said closed distal end of said main tube; and wherein said main tube and said inner tube are parallel through their respective axles and where said inner tube does not have capillarity properties and is very thin in diameter in comparison to said main tube, wherein said inner tube comprises a small aperture at said connecting point; wherein said aperture allows outside air to flow directly inside said inner tube; wherein said inner tube comprises a maximum volume of 1/12th of said volume of said main tube; wherein when a fluid sample is poured inside said main tube said proximal open end of said inner tube is blocked from outside air via an index finger and therefore 1/12th of said fluid sample will be trapped/retained inside said inner tube; then remaining fluid inside said main tube is discarded by tilting said main tube while said index finger is still blocking said proximal end of said inner tube, when said fluid is completely discarded said main tube is tilted upwards to its original position and said index finger is removed allowing said 1/12th of said fluid sample to flow through said distal open end of said inner tube inside said main tube and combined with a sediment.
