Then the blood collection fixing sleeve 202 on the blood collection needle 201 will push The blood transfusion card block 502 slides into the blood transfusion card slot 501. When the blood transfusion card block 502 moves, it compresses the blood transfusion fixing spring 503. When the blood sampling fixing sleeve 202 moves to a suitable position, the blood transfusion fixing spring 503 is used to eject the blood transfusion card block 502 again, thereby achieving the blood transfusion card block 502 and the blood sampling fixing sleeve 202 to fix the blood sampling needle 201. Then, the blood transfusion needle 301 is inserted into the blood sampling slot 600. The blood transfusion needle 301 will first The blood collection sealing plate 607 in the blood collection needle slot 606 is pierced, causing the blood collection self-destructive fixing glue 608 to overflow, and then the blood transfusion fixing sleeve 302 on the blood transfusion needle 301 will push the blood collection card block 602 to slide in the blood collection card slot 601. When the blood collection card block 602 moves, it will compress the blood collection fixing spring 603, so that when the blood transfusion fixing sleeve 302 moves to the appropriate position, the blood collection fixing spring 603 will be used to pop out the blood collection card block 602 again, and then the blood collection card block 602 is used to cooperate with the blood transfusion fixing sleeve 302 to fix the position of the blood transfusion needle 301. The blood transfusion slot 500 and the blood collection slot 600 are used to respectively accommodate the blood transfusion needle 301 and the blood collection needle 201, and are doubly fixed and locked using glue and the card block to prevent them from being collected and reused, and the needle is no longer exposed, so as to avoid injuring medical waste handlers. At the same time, the self-destructive fixing plate 400 can slide on the blood collection tube 100, which is convenient for users to operate.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
