The present invention will be described in detail with reference to the accompanying drawings and specific embodiments thereof.

Referring to fig. 1-4, a sampling device for medical oncology examination comprises an L-shaped placing frame, wherein the placing frame comprises a vertical plate 10 and a horizontal plate 11 which are fixed together, a plurality of supporting blocks 12 are fixed on the vertical plate 10, each supporting block 12 is provided with a semicircular groove 13, and a sampler 20 or a sample barrel 30 is placed in each semicircular groove 13.

Sampler 20 includes sample injection sleeve, the telescopic rear end of sample injection outwards extends and forms sample stop part 26, sample stop part 26 can contact the upper surface of supporting shoe 12, thereby fix sampler 20 in semicircular groove 13, be equipped with sample piston 21 in the sample injection sleeve, sample piston 21 can slide in the sample injection sleeve, the fixed sample pull rod 22 in side of sample piston 21, sample pull rod 22 extends to the telescopic rear end of injection, and fixed sample propelling part 25, the space between sample piston 21 and the telescopic front end of injection is sample space 23, the fixed syringe needle 24 in telescopic front end of injection, liquid outlet 27, syringe needle 24, liquid outlet 27 all communicates sample space 23, liquid outlet 27 is equipped with sampling valve 28.

Sample barrel 30 includes the sample injection sleeve, the telescopic rear end of sample injection outwards extends and forms sample stop 36, sample stop 36 can contact the upper surface of supporting shoe 12, thereby fix sample barrel 30 in semi-circular recess 13, be equipped with sample piston 31 in the sample injection sleeve, the telescopic rear end fixation nut 38 of sample injection, nut 38 screw-thread fit screw rod 32, the fixed barrier plate 39 in front end of screw rod 32, the fixed handle 35 in rear end of screw rod 32, sample piston 31 can slide in the sample injection sleeve, the space between sample piston 31 and the telescopic front end of injection is sample space 33, the telescopic front end fixation inlet 34 of injection, inlet 34 communicates sample space 33, inlet 34 is equipped with sample valve 37.

The sample barrel 30 is divided into a plurality of middle sample barrels and a tail sample barrel, the liquid inlet 34 of the middle sample barrel is communicated with a tee joint 41, all the middle sample barrels are connected in series, specifically, the tee joints 41 of two adjacent middle sample barrels are connected through a hose 40, the liquid outlet 27 of the sampler 20 is communicated with the tee joint 41 of the first middle sample barrel through the hose 40, and the tee joint 41 of the last middle sample barrel is communicated with the liquid inlet 34 of the tail sample barrel through the hose 40.

For safety, the sampler 20 and the sample barrel 30 are made of medical silica gel.
