Improved mycobacterium tuberculosis specimen bacterium collecting device

Abstract

The invention relates to the technical field of tubercle bacillus specimen collection instruments, and discloses an improved tubercle bacillus specimen collection device which comprises a bottle body and a bottle cap, the bottom of the bottle body is fixedly connected with a base, and the bottom of the bottle cap is attached to the top of the bottle body. A rubber inner sleeve is fixedly connected to the position, located on the inner side of the bottle body, of the lower surface of the bottle cap, an elastic supporting piece is arranged on the inner side of the rubber inner sleeve, and an outer sleeve ring is fixedly connected to the position, located on the outer side of the bottle body, of the lower surface of the bottle cap. During use, the bottle body is stably placed through the base, bacteria are collected through the bottle body, after bacteria are collected, the bottle cap is stably plugged in the bottle body through the elastic supporting piece of the rubber inner sleeve, the sealing performance of the bottle body is guaranteed, the bottle cap is arranged on the outer side of the bottle body in a sleeving mode through the outer sleeve ring, then the arc clamping block is clamped in the arc clamping opening, and connection between the bottle cap and the bottle body is guaranteed; and the bottle cap can be conveniently taken down while conveniently covering the opening of the bottle body.

Description

technical field [0001] The invention relates to the technical field of tuberculosis specimen collection equipment, in particular to an improved tuberculosis specimen collection device. Background technique [0002] Clinically, sputum bacterium examination is the most direct and main basis for diagnosing tuberculosis and judging the infectivity of tuberculosis. After the intensive treatment, the lesions will improve, but at this time the Mycobacterium tuberculosis may not be eliminated. Entering the consolidation period of treatment before the sputum bacteria have turned negative may easily lead to the resurgence of Mycobacterium tuberculosis, and even cause drug resistance, so after 2 months of treatment The monthly sputum check is particularly important. If the sputum bacteria have not turned negative, it is necessary to extend the intensive treatment for another month.

[0002] Clinically, sputum bacterium examination is the most direct and main basis for diagnosing tuberculosis and judging the infectivity of tuberculosis. After the intensive treatment, the lesions will improve, but at this time the Mycobacterium tuberculosis may not be eliminated. Entering the consolidation period of treatment before the sputum bacteria have turned negative may easily lead to the resurgence of Mycobacterium tuberculosis, and even cause drug resistance, so after 2 months of treatment The monthly sputum check is particularly important. If the sputum bacteria have not turned negative, it is necessary to extend the intensive treatment for another month. If the sputum bacteria have turned negative, you can safely enter the consolidation phase of treatment. Therefore, the sputum bacteria test is the key to assess the treatment effect of tuberculosis. The most important standard is that drug-resistant tuberculosis, especially multidrug-resistant tuberculosis, is the main reason for the resurgence of the tuberculosis epidemic in my country. The cure rate of MDR-TB patients is less than 25%. effective drug against tuberculosis

[0003] During the use of the existing bacteria collection device, it is easy to be tilted, causing the sputum to leak out, which is easy to cause the spread of tuberculosis bacteria, and in order to ensure the airtightness of the bacteria collection device, the traditional stopper takes a little longer in the operation process Afterwards, some will expand, and some will shrink. After expanding, it will be more difficult to remove the stopper. If it shrinks, bacteria or microorganisms may be contaminated or the liquid in the test tube may be spilled. Therefore, we propose an improved tuberculosis specimen. Bacteria collection device
