Description

Technical Field

[0001] The utility model relates to the technical field of blood testing equipment, in particular to a blood sample impurity filtering device for blood testing. Background Art

[0002] A blood filter is a medical device that is mainly used to remove water and solutes from the blood in order to purify the blood. The working principle of the blood filter is to use a semipermeable membrane filter, in which there is a transmembrane pressure gradient between the blood and the outside of the membrane. When the blood passes through the filter, the water and most of the small and medium-sized molecules in the plasma are filtered out, while formed elements such as proteins and cells are retained in the filter. The blood filter removes water and solutes from the blood by convection, and is more effective in removing medium-sized molecules.

[0003] A blood filter of Chinese utility model with patent number CN219481062U is retrieved, which relates to the technical field of medical devices, including an upper shell, a lower shell and a middle shell connected between the upper shell and the lower shell, a filter screen covering the upper and lower channels of the middle shell is arranged in the middle shell, the upper and lower ends of the middle shell are respectively plug-connected with the upper shell and the lower shell, the cross section of the filter screen is a broken line shape, and the four sides are respectively abutted against the four side walls of the middle shell, the filter screen includes at least one supporting mesh layer and at least one filter cloth layer, and the filter cloth layer is arranged above the supporting mesh layer. The present application divides the blood filter into three parts, upper, middle and lower, and connects them by plugging, and they are mutually connected during installation. The filter is arranged in the middle shell body, and after removing the middle shell body, it is convenient to clean or replace the filter, so that the blood filter can be reused. However, although the disassembly structure of the upper shell body and the lower shell body in the patent can remove and replace the filter, the filter will always leave the impurities between the upper shell body and the filter after filtering the impurities, which is difficult to clean and cannot be used for a long time. When the impurities need to be removed after a period of time, the whole filter can only be disassembled for cleaning, which is troublesome. Therefore, a blood sample impurity filtering device for blood testing is proposed, which can replace the filter tool without disassembly, and can take away the impurities and the filter tool for cleaning after each use.
