safety cap for tubes of drillable sampling of biological fluids

摘要

a stopper (24) drillable - pieces enable the levy for depression of organic liquids - act to be lifted with rotation, and carried out entirely in rubber or equivalent.with a body inside of filling (28) were the diaphragm drillable (38).an outer shroud (26) act to form protection to spray liquid organic in the opening of the test tube.and a mating threaded with a rib protruding from the outer wall of the tube and a helical channel (40) in the inner wall of said shroud (26).to enable the removal of the plug for rotation and the insertion of said stopper for axial reinforcement; regular adjustment of filettature cooperating is achieved with a limited roevaluation on, due to the elastic nature of the stopper.
