[0035] As Figures 1-2The abdominal cavity drainage liquid extraction device shown comprises a puncture part 1, a connecting pipe 2 and a storage bottle 3; one end of the connecting pipe 2 is communicated with the puncture part 1, and the other end is communicated with the storage bottle 3; the inside of the storage bottle 3 is provided with a vacuum; a water stop clamp 4 is arranged on the outer wall of the connecting pipe 2; the puncture part 1 comprises a holding piece 11, a protective sleeve 12, a puncture needle 13 and a reset piece 14; one end of the holding piece 11 is fixedly connected with the puncture needle 13, and the other end is connected with the connecting pipe 2; the inside of the holding piece 11 is provided with a through hole, so that the puncture needle 13 and the connecting pipe 2 are communicated; the protective sleeve 12 is wrapped outside the puncture needle 13, and the protective sleeve 12 moves linearly along the axial direction of the puncture needle 13; one end of the holding piece 11 away from the connecting pipe 2 is provided with a sliding cavity 112; one end of the protective sleeve 12 is inserted into the inside of the sliding cavity 112; the reset piece 14 is located in the inside of the sliding cavity 112; one end of the reset piece 14 is connected with the protective sleeve 12, and the other end is abutted against the inner wall of the sliding cavity 112.
[0036] The protective sleeve 12 is wrapped outside the puncture needle 13, and the protective sleeve 12 moves linearly along the axial direction of the puncture needle 13. When the puncture needle 13 is inserted into the abdominal cavity drainage tube sampling port, one end of the protective sleeve 12 away from the holding piece 11 is abutted against the abdominal cavity drainage tube sampling port, and as the puncture needle 13 gradually enters the inside of the sampling port, the protective sleeve 12 gradually enters the inside of the holding piece 11 and compresses the reset piece 14.
