A sputum tank with smear function

Abstract

The invention discloses a sputum pot with a smearing function. The sputum pot comprises a small cover, a duck-mouth type large cover, a bottle body, a ball and an elastic bracket, wherein the small cover is detachably connected to the top of the duck-mouth type large cover in a sealing manner; the bottom of the duck-mouth type large cover is detachably connected to an opening of the bottle body in a sealing manner; a flat mouth part with an inner hole which gradually becomes small is arranged at the top of the duck-mouth type large cover; a coating surface with a liquid outlet is arranged on the top end of the mouth part; the elastic bracket is mounted in the mouth part; a concave pit is formed in the top of the elastic bracket; the bottom of the ball is supported by the concave pit; one small part of the ball is exposed out of the liquid outlet of the coating surface; the inner diameter of the liquid outlet is smaller than the diameter of the ball. On one hand, the efficiency of homogenized smearing is improved and the risk of contacting a sputum specimen by an operator is reduced; on the other hand, the amount of the smeared sputum specimens in each time is in a certain range and the smearing is uniform so that the smearing operation can easily realize standardization, the random errors are reduced and the production efficiency is improved.

Description

technical field [0001] The invention relates to a sputum tank with a smear function. Background technique [0002] It is well known that direct smear staining of sputum samples plays an important role in the diagnosis of bacterial diseases such as tuberculosis. At present, the most commonly used method is to use conventional sputum pots to collect patients' sputum samples, and use bamboo sticks to manually pick out suspicious lesions of the sputum samples and spread them on glass slides to form about 10×20mm sputum membrane staining for microscopic examination. [0003] Because the distribution of Mycobacterium tuberculosis in sputum samples is uneven, and because sputum is highly viscous, it is difficult to manually pick and smear, so the existing technology relies heavily on the experience and responsibility of the operator, and the test results are highly random. and lower sensitivity. In order to reduce the random error of direct smear staining microscopic examination ...

Problems solved by technology

[0003] Because the distribution of Mycobacterium tuberculosis in sputum samples is uneven, and because sputum is viscous, it is difficult to pick and smear manually, so the existing technology relies heavily on the experience and responsibility of the operator, and the test results are highly random. sex, the sensitivity is also low

In order to reduce the random error of direct smear staining microscopic examination of sputum specimens and improve the sensitivity, it is best to adopt a homogeneous smear method, that is, to liquefy the sputum specimen first and then smear. Open the sputum tank for the first time, and press the sputum tank on the vortex shaker for about ten minutes during liquefaction, which will increase the labor intensity of the operator, and also increase the risk of contamination due to the highly infectious nature of tuberculosis sputum specimens
