As shown in fig. 10, the inner surface of the wrapping portion 52 at the lower side of the first magnetic block 53 is further adhered with a sponge block 532, and the sponge block 532 is semi-cylindrical.
When the blood sampling device is used, the wrapping part 52 resets under the elastic action, the sponge block 532 is contacted with the needle heads, so that the sponge block 532 can adsorb the blood remained on the two needle heads, the blood is prevented from dripping, and secondary pollution can be further avoided.
