Problems solved by technology
[0002] At present, when sampling in medical examinations, needle tubes are mostly used to draw the liquid to be tested into the needle tube. Although there are scales on the needle tube, when quantitative sampling is performed, medical staff are required to draw according to the scale on the needle tube. Skilled medical staff, Quantitative sampling can be easily carried out, but for novices, direct quantitative sampling is not possible, which is troublesome. If the sample liquid is too much or too little, the detection error will increase

The invention provides a medical test sampling device, which relates to the field of medicine. The medical inspection sampling device includes a limit mechanism, the bottom of the limit mechanism includes a cylinder, a scale, a first through hole, a connecting ring and a liquid inlet mechanism, and the inner wall of the limit mechanism is connected to the surface top of the cylinder. threaded connection, the surface of the cylinder is fixedly connected to the side of the scale near the center of the cylinder, the first through hole is opened at the bottom of the cylinder, and the bottom of the cylinder is fixedly connected to the top of the connecting ring, so The inner wall of the connecting ring is threadedly connected with the surface of the liquid inlet mechanism, the surface of the liquid inlet mechanism cooperates with the inner wall of the first through hole, and the inside of the limiting mechanism includes a piston mechanism. In the medical inspection and sampling device, the fixed plate acts as a limiter for the piston block. After the piston block rises to a designated position, the piston block cannot continue to move upward under the action of the fixed plate, thereby realizing quantitative material taking.
Description
technical field [0001] The invention relates to the field of medical technology, in particular to a medical inspection sampling device. Background technique [0002] At present, when sampling in medical examinations, needle tubes are mostly used to draw the liquid to be tested into the needle tube. Although there are scales on the needle tube, when quantitative sampling is performed, medical staff are required to draw according to the scale on the needle tube. Skilled medical staff, Quantitative sampling can be easily done, but for novices, it is difficult to directly quantitative sampling, and if the sample liquid is too much or too little, the detection error will increase. Contents of the invention [0003] The object of the present invention is to provide a medical inspection sampling device with reasonable structure and novelty, which is convenient for quantitative sampling. [0004] Technical solutions [0005] In order to achieve the above purpose, the present inv...
