Description

An insulated transportation device suitable for multi-standard gonorrhea culture tubes

technical field

The utility model relates to the technical field of inspection devices, in particular to an insulated transportation device suitable for multi-standard gonorrhea culture tubes.

Background technique

Neisseria gonorrhoeae is a typical fastidious bacterium, and the best growth conditions are aerobic and 35-37 ℃ temperature. According to the Health Industry Standard of the People's Republic of China - Collection and Transport of Specimens for Clinical Microbiology Examination (WS/T640-2018): For male genitourinary tract and female cervical specimens, secretions collected for culture should be stored in transport media for inspection . Gram-negative diplococci in white blood cells detected by Gram staining of urethral secretions can be used as the basis for the diagnosis of male gonorrhea patients, but according to the data, the sensitivity of cervical smears and rectal smears of gay men is only about 50%, so it is more dependent on in cultivation method. In addition, the resistance of gonorrhoeae to various antibiotics is increasing. According to literature reports, strains resistant to the first-line drug azithromycin and other drugs of gonorrhea have appeared in my country. The discovery of multidrug-resistant strains has brought great threats and challenges to gonorrhea treatment programs at home and abroad. Improving the positive rate of Neisseria gonorrhoeae culture and conducting in vitro drug susceptibility tests in time will help the precise treatment of Neisseria gonorrhoeae in clinic. However, in actual work, the positive rate of Neisseria gonorrhoeae is not satisfactory. One of the most important reasons is that Neisseria gonorrhoeae is extremely sensitive to temperature. If it is not sent for inspection in time, it is likely to cause false negatives in culture.

When designing the insulated transportation device for gonorrhoeae culture tubes, the following technical issues need to be considered: 1. How to have good heat preservation performance; 2. How to adapt to gonorrhea culture tubes of different specifications; 3. Minimize the space used when placing samples ; 4. Keep the culture tube upright during transportation and not topple over.

2. The transportation device of the utility model can keep the gonorrhea culture tubes placed upright in the transportation device, avoiding medium outflow and sample contamination caused by dumping. The device can be directly placed in the specimen transport incubator, which is convenient to take.

3. The rubber and plastic materials are light and thin, occupying a small space, and will not increase the burden on the workers who transport the specimens.

4. Rubber and plastic materials have low thermal conductivity and excellent thermal insulation performance, which can meet the requirements of Neisseria gonorrhoeae insulation and inspection, and improve the positive rate of Neisseria gonorrhoeae detection.

5. The device of the utility model is suitable for the heat preservation and inspection of the gonorrhea culture tube in clinical practice, and the heat preservation of the gonorrhea transport culture tube can improve the positive rate of culture.
