  • Patent number: 9404910
    Abstract: A body fluid testing apparatus with testing and storing functions is provided, which comprises a body, a cover, at least two body fluid collectors and a testing element. The body comprises a fluid storing chamber, a testing chamber and a partition wall. The fluid storing chamber and the testing chamber are divided by the partition wall. The body is covered by the cover with at least two through-holes through which the body fluid collectors respectively enter into the fluid storing chamber and the testing chamber. The testing element is inserted into the testing chamber. Pollution is avoided, which results from that the body fluid in the testing chamber cannot flow back into the fluid storing chamber.
