Problems solved by technology

[0007] The purpose of the present invention is to provide a vortex tube and plasma microfiltration structure, which can solve the problem that blood cells block the blood filter membrane and cause the plasma to fail to filter when the whole blood is microfiltration plasma, thereby improving the efficiency of whole blood microfiltration plasma , to prevent blood cells from being squeezed and damaged during the microfiltration process

Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0031] A vortex tube and plasma microfiltration structure, such as image 3 As shown, a step is provided in the filter chamber 9, and a filter assembly 7 is placed on the step of the filter chamber 9. The filter assembly 7 is preferably a blood filter membrane 1, and a vortex tube is set above the blood filter membrane 1. 4. Vortex tube 4 is driven and sealed by plunger 8.

[0032] Such as image 3 As shown, the vortex tube 4 has a first flow path, and...

Abstract

The invention discloses a vortex tube and a plasma microfiltration structure. The vortex tube structure comprises a vortex tube with a first flow channel, wherein at least one vortex inlet and at least one vortex outlet are formed in the wall surface of the vortex tube; each vortex inlet is positioned at the upstream of the vortex outlet, and the vortex inlet is communicated with a corresponding vortex outlet to form a second flow channel; the diameter of the first flow channel is larger than that of the second flow channel; an included angle is formed between the outlet direction of the vortex outlets and the length direction of the vortex tube, so that liquid flowing out of the second flow channel forms vortex. According to the vortex tube disclosed by the invention, the plasma microfiltration efficiency in whole blood is improved, and blood cells are prevented from being extruded to damage in the microfiltration process.

Description

technical field [0001] The invention relates to a vortex tube and a plasma microfiltration structure, belonging to the field of plasma filtration equipment. Background technique [0002] The mixture formed by collecting the blood in the human body into the blood collection bag is called whole blood, which includes all components of blood cells and plasma. The whole blood leaving the blood vessel is subjected to anticoagulant treatment and centrifuged to obtain a liquid without cell components, that is, plasma. Most of the pharmacokinetic experiments use plasma. [0003] 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 corresponds to the intercellular substance of connective tissue. Plasma is an important part of blood and is a light yellow liquid (because it contains bilirubin). In the chemical composition of plasma, water accounts for 90-92%, and the other 10% is ma...
