SAMPLING METHOD OF BLOOD PLASMA FOR CLINICAL INSPECTION

PURPOSE:To sample quickly and easily several 100mul-several ml blood plasma necessary for an inspecton from the whole blood of several ml-10ml by feeding the whole blood into the hollow parts of hollow fibers and filtering the blood plasma on the outside surface of the hollow fibers. CONSTITUTION:A filter cartridge at least one end of which is fixed by an adhesive resin 2 is used and the whole blood is fed from the stationary open end into the hollow parts of hollow fibers 1 and is led out of the other open end so that the blood plasma is filtered and separated on the outside surface of the filbers 1, thereby sampling the blood plasma for an inspection. The blood is sampled from a patient into a syringe then the injection needle is removed and the syringe 6 is coupled via a suitable adapter 5 to a main cartridge 7. The inside cylinder of the syringe is then moved to feed the blood in the syringe into the cartridge. The blood which is forced to the other open end and contains much blood cell component is discarded. The fibers having the membrance structure as mentioned above has high mechanical strength and provides a high rate of separating the blood plasma and therefore the quick and sure analysis of a small amt. of specimen (blood) is made possible without errors.
