Problems solved by technology
[0003] The purpose of the present invention is to solve the shortcomings in the prior art, such as: most of the existing sampling devices do not have the function of quantitative sampling. When sampling, if the sampling volume is too small to meet the needs of diagnosis, it is necessary to re-sampling , if the sampling volume is too much, it will be troublesome to deal with the excess cells, and a quantitative sampling device for cell diagnosis is proposed

The invention relates to the technical field of medical instruments, and discloses a novel quantitative sampling device for cell diagnosis. The device comprises a supporting plate, wherein a first thread ring is fixedly connected to the bottom of the supporting plate; a sampling needle is in threaded connection with the inner wall of the first thread ring; a pushing mechanism is arranged on the upper surface of the supporting plate; and the inner wall of the supporting plate and the inner wall of the sampling needle are both in sliding connection with the surface of the pushing mechanism. Through the arrangement of the pushing mechanism, a sampling sleeve, an air exhaust sleeve, an air exhaust mechanism, an air duct, a sealing mechanism and air vents, after cells enter the sampling sleeve,the gravity of the sampling sleeve is increased, when the gravity of the sampling sleeve is greater than that of a first spring, the sampling sleeve moves downwards, the air duct is opened, at the moment, an air exhaust plate cannot continue to drive a sliding plate to move upwards, the sliding plate returns to an initial position under the action of a second spring, a fourth straight tube and the bent tube are sealed, and then the cells are extracted, and quantitative sampling is achieved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a quantitative sampling device for cell diagnosis. Background technique [0002] At present, cell diagnosis is mainly to use a syringe and a needle to absorb the cells of the lesion. When the needle tip passes through the skin and subcutaneous tissue to reach the lesion under normal pressure, a negative pressure is generated in the syringe by pulling the piston core rod to absorb the lesion. The cells then exit the subcutaneous tissue and skin, and the diseased cells are placed on a smear for observation. However, most of the existing sampling devices do not have the function of quantitative sampling. For example, the Chinese patent announcement number CN201720431678.4 discloses a needle aspiration cell sampler. The sampler draws cells into the syringe through a piston. However, in the process of sampling, it is impossible to determine the sample volume of cells. If the ...
