DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1 and Figure 2As shown, a tumor blood filter for quickly separating blood includes a shell 1 and an upper cover 2, the shell 1 and the upper cover 2 are threadedly connected, the middle part of the upper cover 2 is connected to an inlet blood vessel 3, and the middle part of the bottom end of the shell 1 is connected to an outlet blood vessel 4, a filter assembly is arranged in the shell 1, the filter assembly includes a filter cylinder 5, a diverter block 6, a first bracket 7, a second bracket 8 and a filter membrane 9, the filter cylinder 5 is connected to the inner wall of the shell 1, the diverter block 6 is located in the middle of the inner side of the shell 1, a vibration motor 17 is embedded in the diverter block 6, the diverter block 6 has a truncated cone structure, and a plurality of guide grooves 18 are evenly spaced on the outer circumference of the diverter block 6, the bottom end of the diverter block 6 is vertically connected to a plurality of first brackets 7, the other end of the first bracket 7 is vertically connected to the second bracket 8, the other end of the second bracket 8 is connected to the bottom end of the inner wall of the filter cylinder 5, and the filter membrane 9 is arranged between each first bracket 7 and the second bracket 8.

[0018] See also Figure 1 and Figure 3 As shown, an annular groove is provided on the top inner wall of the shell 1, and an annular plate 10 is provided above the annular groove. The bottom surface of the annular plate 10 is connected to the annular groove by a number of springs 11. A fixing plate 12 is provided on the outer wall of the top surface of the filter cylinder 5. A number of fixing ports 13 are provided on the fixing plate 12 at equal intervals. A number of corresponding L-shaped blocks 14 are provided on the top surface of the annular plate 10 at equal intervals. A protrusion 15 is extended upward to form a protrusion 15. A groove 16 that fits with the protrusion 15 is provided on the bottom surface of the upper cover 2. The setting of the protrusion 15 and the groove 16 can increase the sealing between the shell 1 and the upper cover 2 through the concave-convex structure.

[0019] The working principle of this embodiment is as follows:

[0020] Blood is transported into the housing 1 through the inlet blood vessel 3 and the vibration motor 17 is activated at the same time. The blood immediately falls onto the diverter block 6 upon entering the housing 1, and then splashes around from the diverter block 6 and falls into the bottom of the filter cylinder 5. Tumor cells are quickly separated from the blood by the filter membrane 9 on the first bracket 7 and the second bracket 8. The bent filter membrane 9 can greatly increase the filtration area compared to a flat filter membrane 9. Combined with the diversion effect of the diverter block 6, the blood can be dispersed to all surfaces, so that the filter membrane 9 is fully utilized and the filtration rate is improved. At the same time, the filter membrane 9 on the first bracket 7 is in a vertical state and continuously vibrates under the drive of the vibration motor 17. The filtered tumor cells are not easily attached to it, which can prevent the filter membrane 9 from being blocked. Finally, the filtered blood is connected to the blood transfusion device through the outlet blood vessel 4 and transported into the patient's body.

[0021] When the filter membrane 9 is replaced or cleaned, the upper cover 2 is unscrewed, the protrusion 15 is pinched, and the filter cylinder 5 is rotated counterclockwise to rotate the fixing port 13 out of the L-shaped block 14. The filter cylinder 5 can be taken out. The opposite is true for installation.

[0022] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
