Abstract
the invention relates to a filter element of an adsorption filter which comprises an active carbon fiber layer and polyester fiber non-woven fabric filter membrane layers and is characterized in that the filter element consists of the fiber non-woven fabric filter membrane layers and an active carbon fiber layer at intervals, wherein, both the top level and the bottom of the fiber element are thepolyester fiber non-woven fabric filter membrane layers. More particularly, the filter element consists of a layer of PBT polyester fiber non-woven fabric filter membrane layer with the aperture of 35 Mum, there layers of PBT polyester fiber non-woven fabric filter membrane layers with the aperture of 22 Mum, two layers of active carbon fiber layers, a layer of PBT polyester fiber non-woven fabric filter membrane layer with the aperture of 22 Mum, one layer of active carbon fiber layer, a layer of PBT polyester fiber non-woven fabric filter membrane layer with the aperture of 22 Mum and a layer of PP polyester fiber non-woven fabric filter membrane layer, sequentially from up to down. The filter element of the invention has the advantages of improving the quality of blood transfusion, reducing the reaction of transfusion reaction and blocking little concretion in blood.
Description
Technical field
Patent of the present invention relates to the correlative technology field of medical apparatus and instruments, particularly a kind of filter-core of absorption filtering device.
Background technology
In the process of blood filtration, need be to the absorption and the leukocytic filtration of methylene blue medicinal liquid in the blood, allow clinical blood transfusion is more effective to be prevented transfusion reaction and improve the blood transfusion quality.
Summary of the invention
The purpose of patent of the present invention is in order a kind of filter-core of absorption filtering device to be provided, to improve the blood transfusion quality greatly, reducing small coagulum in transfusion reaction and the block blood.
For achieving the above object, patent of the present invention has adopted following technical scheme:
Patent disclosure of the present invention a kind of filter-core of absorption filtering device, comprise NACF layer, polyester fiber non-woven fabrics filter membranous layer, it is characterized in that: every constituting, wherein top layer and bottom are polyester fiber non-woven fabrics filter membranous layer to described filter element by polyester fiber non-woven fabrics filter membranous layer and NACF interlayer.
As a kind of preferred version, described filter element from top to bottom is made of 4 strata ester fiber non-woven fabrics filter membranous layers, 2 layers of NACF layer, 1 strata ester fiber non-woven fabrics filter membranous layer, 1 layer of NACF layer and 2 strata ester fiber non-woven fabrics filter membranous layers successively.
In particular, described filter element is that PBT polyester fiber non-woven fabrics filter membranous layer and 1 layer of PP polyester fiber non-woven fabrics filter membranous layer that the PBT polyester fiber non-woven fabrics filter membranous layer of 35 μ m, the 3 layers of aperture PBT polyester fiber non-woven fabrics filter membranous layer that is 22 μ m, 2 layers of NACF layer, the 1 layer of aperture PBT polyester fiber non-woven fabrics filter membranous layer that is 22 μ m, 1 layer of NACF layer, 1 layer of aperture are 22 μ m constitutes by 1 layer of aperture successively from top to bottom.
The advantage of Patent equipment of the present invention is: improve the blood transfusion quality reduce transfusion reaction and can block blood in small coagulum.
Description of drawings
Fig. 1 is the structural representation of patent of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples patent of the present invention is further described.
A kind of filter-core of absorption filtering device, as shown in Figure 1, be that the PBT polyester fiber non-woven fabrics filter membranous layer 1 of 35 μ m, three layers of aperture are that the PBT polyester fiber non-woven fabrics filter membranous layer 2 of 22 μ m, two-layer NACF layer 3, one deck aperture are that PBT polyester fiber non-woven fabrics filter membranous layer 4, layer of active carbon fibrous layer 5, one deck aperture of 22 μ m is that PBT polyester fiber non-woven fabrics filter membranous layer 6 and one deck PP polyester fiber non-woven fabrics filter membranous layer 7 of 22 μ m constitutes by one deck aperture successively from top to bottom.
