CN2757552Y - Biphase culturing bottle - Google Patents

Abstract

The utility model relates to a biphase culturing bottle belonging to the technical field of a bacteria culture appliance. The utility model comprises a bottle body. The side wall on the middle upper part of the bottle body is outward bulged to form one solid culture medium set space or two solid culture medium set spaces or a plurality of solid culture medium set spaces. Using the utility model can save the consumption of the solid culture medium and can increase bacteria culture species. The utility model not only can be used for blood bacteria culture but also can be used for pathogen culture of various body fluids of cerebrospinal fluid, hydrothorax, ascites, etc.

Description

A kind of biphasic culture bottle

Technical field

The utility model belongs to bacterial culture utensil technical field, particularly a kind of blake bottle that adopts solid culture medium and increase bacterial context soup biphasic culture.

Background technology

Blood culture is one of most important Interventions Requested in the clinical medicine laboratory, nearly all disease such as various bacteria infectious disease, pneumonia, meningitis, urinary system infection contamination, peritonitis, osteomyelitis, postpartum pyemia, bacterial endocarditis and fever of unknown patient etc., all may cause bacteremia, septicemia because of bacterium enters blood.This is serious and critical general symptom, must in time give and antibacterial therapy targetedly, and find out that accurately and timely pathogen is the prerequisite of Clinics and Practices in the blood.Generally carry out blood culture clinically and find out pathogen in the blood by Blood culture bottle.Existing diphase blood culture flask comprises bottle, adheres to solid culture medium on a side of bottle, and bottle is gone in blood sampling then, under uniform temperature, the cultivation of certain hour, can observe the bacterial growth situation on solid culture medium.Use this blake bottle can shorten the inspection bacterium time, simplify the operation and reduce pollution, but also have the following disadvantages: (1) solid culture medium sticks in the bottle from bottle end to a side of bottleneck, and the solid culture medium consumption is more; (2) solid culture medium on the bottle side some contact with culture fluid in the bottle all the time, solid culture medium can not be preserved for a long time, and easily comes off; (3) can only adopt a kind of solid culture medium, the bacterial culture kind is few.

The utility model content

One of the utility model purpose is to provide a kind of biphasic culture bottle of saving the solid culture medium consumption; Its further purpose is to provide a kind of not only can save the solid culture medium consumption, but also can increase the biphasic culture bottle of bacterial culture kind.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: a kind of biphasic culture bottle, comprise bottle, and bottle middle and upper part sidewall outwards convexes to form solid culture medium the space is set.

Two side, bottle middle and upper part correspondence outwards convexes to form solid culture medium the space is set.

The bottle middle and upper part a plurality of parts of sidewall outwards convex to form solid culture medium the space are set.

The utility model earlier is provided with the side, space at the solid culture medium of bottle internal projection and smears and adhere to solid culture medium in use, and blood sampling is gone into bottle and cultivated through uniform temperature, a period of time then, just can observe bacterial growth situation on the solid culture medium through bottle.Because having designed protruding solid culture medium at bottle side wall is provided with the space, the solid culture medium consumption that adheres to bottle side wall in the use can reduce 70%; The solid culture medium of projection is provided with the space and can designs more than two, can add two or more solid culture mediums simultaneously, cultivates two or more bacteriums simultaneously, and the bacterial culture kind increases; In the incubation, the culture fluid in the bottle separates with solid culture medium, long, difficult drop-off of solid culture medium holding time.Through test, utilize the positive rate of the utility model gained to improve 2-3 doubly than conventional method.The utility model can be used for the blood bacterial culture, and the pathogen that also can be used for multiple body fluid such as cerebrospinal fluid, hydrothorax, ascites is cultivated.
