Problems solved by technology

[0005] Please refer to Figure 13 As shown, the circular white blood cell filter 60 adopts a circular filter material 62. When mass-produced, because the filter material original sheet 80 is a rectangle, although a large amount of filter material 62 can be smoothly cut with a circular cutting line 81, But also therefore cause too much waste 800, not only waste but also difficult to reduce manufacturing cost, can't make more blood recipients accept the blood transfusion of high blood product; Therefore, it is necessary to further improve

Embodiment Construction

[0086] The invention improves the blood filter, reduces its manufacturing cost, improves the purchase willingness of medical units related to blood transfusion, and ensures that blood recipients can obtain blood with high blood quality. The technical content of the present invention will be described in detail below with a plurality of embodiments in conjunction with the drawings.

[0087] See first figure 1 , figure 2 and image 3 As shown, the first preferred embodiment of the blood filter 10 of the present invention includes: a housing 20 and a filter material 30 . The casing 10 includes a first shell 21 and a second shell 22, an outer surface of the first shell 21 forms a liquid inlet pipe 23, and an outer surface of the second shell 22 forms a liquid The outlet pipe 24 ; moreover, an inner surface of the first housing 21 is formed with a plurality of parallel first ribs 212 , and an inner surface of the second housing 22 is formed with a plurality of parallel second ...

Abstract

The invention discloses a blood filter, its filter material and its manufacturing method. In the blood body filter, the filter material is fixed in a casing. A concave portion is formed on the side, and the main body has two parallel outer sides; in this way, when a filter material original sheet is cut out of a plurality of filter materials, the waste can be effectively reduced or even eliminated, so as to increase the output of the filter material and reduce the The production cost of the blood filter.

Description

technical field [0001] The invention relates to a blood filtration technology, especially a blood filter. Background technique [0002] Human blood contains three main types of blood cells: red blood cells, white blood cells and platelets. During the recipient's blood transfusion, all the blood in the blood bag is injected into the recipient's body, so the donor's red blood cells, white blood cells and platelets will enter the recipient's body. Medical research has pointed out that when the white blood cells of the blood donor enter the body of the recipient, the recipient will have a certain chance of having an allergic reaction, and it may also be because the virus attached to the white blood cells enters the body of the recipient, causing the recipient to cause complications due to blood transfusion. disease; therefore, reducing the number of white blood cells in blood for transfusion will help improve the quality of blood transfusion. [0003] At present, a leukocyte f...
