Sampling device for medical examination

The utility model discloses a sampling device for medical examination. The sampling device comprises a glass pipette, a conical suction nozzle, a shell and a pneumatic bag, wherein the conical suction nozzle is arranged at the lower end of the glass pipette; a barrier plug is arranged at the top end of the glass pipette; a gas circulation gap is formed between the outer wall of the barrier plug and the inner wall of the glass pipette; a liquid inlet pipe is arranged in the middle of the glass pipette and below the barrier plug; a sleeve is movably arranged on the outer wall of a liquid storage pipe; the upper end of the glass pipette is communicated with the pneumatic bag; a press body in an arc-shaped structure is arranged at the upper end of the shell. The sampling device has the beneficial effects that the contact area of a thumb and a control button can be increased by the press body in the arc-shaped structure and the pressure on the thumb is reduced, and thus the use comfortableness is improved; as the barrier plug is arranged below the rubber pneumatic bag, a sample liquid can flow back to the liquid storage pipe by a first connecting pipe; meanwhile, the sleeve made from lighttight materials slides on the liquid storage pipe, so as to prevent samples to be examined from deteriorating when the samples to be examined are exposed in light.
