Rapid peripheral plasma collector and use method thereof

Abstract

The invention discloses a rapid peripheral plasma collector which comprises a collection assembly and a mounting assembly, a disinfection box is filled with disinfection alcohol cotton through an injection hole, a mounting base and an outer plastic body are screwed together in a threaded mode, the lower end of the mounting base is aligned with a finger, a handle and a force application rod are tightly pressed, and the finger is punctured after a collecting needle is pointed, then taking down the mounting base and the collecting needle, putting a capillary aligned to the bleeding position for peripheral plasma collection, keeping the handle and the force application rod are continuously pressed, blood will enter the capillary, and the peripheral plasma collection work is completed through separation of a hemofilter. The invention further discloses a use method of the rapid peripheral plasma collector, blood is collected in the capillary through a seepage plate, a stop block can be used to prevent the blood from entering the collection tube, when the handle and the force application rod are loosened, a piston moves upwards, so that negative pressure is formed in the capillary and drive the blood to flow upwards, so that blood can be filtered by the hemofilter to separate plasma and red blood cells, and the operation is simple.

Description

technical field [0001] The invention relates to the technical field of peripheral plasma collectors, in particular to a rapid peripheral plasma collector and its usage method. Background technique [0002] The main function of plasma is to carry blood cells, transport substances needed to maintain human life activities and waste generated in the body. Plasma is equivalent to the intercellular substance of connective tissue. Serum refers to the light yellow transparent liquid separated from the plasma after removing fibrinogen and some coagulation factors after blood coagulation, or refers to the plasma from which fibrinogen has been removed. At present, Many rapid tests require the use of plasma for testing, so plasma separation is particularly important. [0003] Existing peripheral plasma collectors cannot separate plasma from serum, and are difficult to operate. In addition, blood collection needles and blood collection tubes are required in the blood collection process,...

AI Technical Summary

Problems solved by technology

[0003] Existing peripheral plasma collectors cannot separate plasma from serum, and the operation is difficult. In addition, in the process of blood collection, blood collection needles and blood collection tubes are required, which cannot be used in combination, and the use effect is not good.
