Embodiment Construction

[0017] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] refer to Figure 1 to Figure 4 , a preferred embodiment of the present invention provides a blood nanofilter, including an outer tube 7 and a hollow inner tube 1, and the outer side of the hollow inner tube 1 is sequentially provided with a first membrane-side spacer layer 2, a first filter membrane 3, and a porous isolation layer 4 1. The second filter membrane 5 and the second membrane-side spacer layer 6, a cavity is set between the second membrane-side spacer layer 6 and the outer tube 7, and a plurality of permeation holes are set on the hollow inner tube 1.

[0019] A number of evenly distributed support spacers 8 are arranged between the second membrane-side spacer layer 6 and the outer tube 7 , and the support spacers 8 divide the cavity into several blood-inlet chambers 9 .

[0020] The supporting spacer 8 is fixed by several...

Abstract

The invention provides a blood nanofilter which comprises an outer tube and a hollow inner tube, wherein a first membrane side interlayer, a first filter membrane, a porous isolating layer, a second filter membrane and a second membrane side interlayer are successively arranged on the outer side of the hollow inner tube; a cavity is formed between the second membrane side interlayer and the outertube; and a plurality of permeable holes are formed in the hollow inner tube. The blood nanofilter provided by the invention is simple in structure and convenient to use, controls and matches the filtering resistance of blood effectively, can filter leucocytes in blood effectively, and can meet the demand of a patient in blood supply.

Description

technical field [0001] The invention relates to the technical field of blood filtration, in particular to a blood nano filter. Background technique [0002] Generally speaking, blood is responsible for the important work of oxygen and energy transmission in organisms, and is one of the indispensable elements for the normal operation of living systems. When the human body suffers from massive blood loss, blood transfusion is one of the necessary emergency measures. For some patients, such as those suffering from special blood diseases, cancer patients receiving chemotherapy, or patients receiving bone marrow transplantation, the number of blood transfusions is even higher. much higher than the average person. Based on this point, various blood-centered application technologies have been developed in the fields of clinical treatment and medical testing. It is hoped that by accurately and quickly obtaining and analyzing cells or substances contained in blood, further solving t...
