The paper feeding module has a test paper box, a lifting mechanism, and a pushing mechanism. A horizontal paper leakage groove is disposed at a bottom of the test paper box to receive a bottommost piece of test paper. The lifting mechanism lifts and descends the test paper box to reveal/seal the paper leakage groove. The pushing mechanism pushes out test paper from the paper leakage groove and delivers test paper to the sample adding and testing modules. The sample adding module dropwise adds urine to be tested on test paper. The testing module tests test paper added with the sample to obtain a urine testing result. ## Claims ### Claim at position 1 1-10.
