Body fluid culture bottle

Abstract

The invention discloses a body fluid culture bottle. The body fluid culture bottle comprises a culture bottle body containing a culture medium and an indicator. The culture bottle body comprises a bottle body, a rubber plug and a bottle cap, wherein the rubber plug and the bottle cap are used for sealing the bottle body. The fluid culture medium and mixed gas for forming necessary conditions for growth of microorganisms are contained in the bottle body of the culture bottle body, and the interior of the culture bottle body is a negative pressure sterile environment. The indicator is a plastic transparent fluid reservoir externally connected with a long pointer, a plastic cap is arranged on the fluid reservoir, a sleeve connected with the culture bottle body is arranged on the lower half portion, and the long pointer is located in the center of the sleeve and communicated with the fluid reservoir. Aerobic and anaerobic culture can be conducted at the same time, the trouble of inoculation of two culture bottles is saved, the sampling quantity can be reduced, and the problem that samples are distributed in the two bottles, so that the sample capacity is small and the problem that anaerobic bacterium culture is neglected are solved.

Description

technical field [0001] The invention relates to a microorganism culture device for clinical testing, in particular to a body fluid culture bottle. Background technique [0002] With the increase of morbidity and mortality caused by clinical bacterial infection, clinical body fluid culture, especially blood culture has been paid more attention. For example, the incidence of bloodstream infection (bacteremia, sepsis, sepsis, etc.) increased from 1.6% in 1986 to 3.1% in 2006, and the case fatality rate reached 21.0%-48.0%. However, there are still some problems in body fluid culture at present. Insufficient sampling volume affects the growth of microorganisms, and the cultivation of anaerobic bacteria is not taken seriously. When patients have suspected infection, antibacterial drugs are often used first according to experience, and aerobic bacteria are only used after antibacterial drugs are ineffective. Anaerobic culture should be considered only when aerobic culture is nega...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a body fluid culture bottle, which can carry out aerobic and anaerobic culture at the same time, avoid the trouble of inoculating two culture bottles, and can reduce the amount of sampling, and solve the problem of dividing the sample into two bottles. The problem of small sample size and the neglect of anaerobic culture
