Abstract

The utility model discloses a biphasic blood culture bottle, in particular to a biphasic blood culture bottle which adopts solid culture substrate and peptone broth, comprising a bottle body, a bottle lid which is rotated at the neck of the bottle body. A separating part is arranged at one side face of the interior of the bottle body and the solid culture substrate is adhered to one side face between the separating part inside the bottle body and the bottle neck. When in use, the solid culture substrate is firstly adhered to the interior of the empty bottle and next blood is sent to the bottle for culture. The bacteria growth can be judged through the change of the color inside the bottle. The utility model has the advantages of less solid culture substrate, convenient judgment and high detection rate.

Description

A kind of diphase blood culture flask

Technical field:

The utility model relates to a kind of diphase blood culture flask, especially adopts solid medium and the diphase blood culture flask that increases bacterial context soup.

Background technology:

Blood culture is one of most important Interventions Requested in the clinical medicine laboratory, the nearly all fever diseases and the patient of fever of unknown, all may cause bacteremia and septicemia because of bacterium enters blood, this serious and critical systemic infection is badly in need of finding out fast the pathogen in the blood, just can give antibacterial therapy targetedly.Find out the pathogen in the blood, generally can realize, but bacterium is just asked in nutrition that because of its nutritional requirement height, common Blood culture bottle then can not satisfy its requirement as haemophilus influenzae, diplococcus meningitidis, streptococcus pneumonia by common Blood culture bottle.For addressing this problem, produced diphase blood culture flask, be about to solid medium and stick on the interior side of bottle, the bottle of taking a blood sample then then can be observed the phenomenon whether bacterial growth is arranged through the cultivation of uniform temperature, time on the solid culture basal plane.Yet, the deficiency that existing diphase blood culture flask also exists is: 1, some contacts with nutrient solution all the time owing to a solid medium in the bottle, then can not add developer in solid medium, a lot of small bacterium cause " false negatives " not easy to identify make recall rate low; 2, solid medium is to stick in the bottle from the bottle end to a side of bottleneck, and the consumption of solid medium is more.

Summary of the invention:

Technical problem to be solved in the utility model is that the structure of above-mentioned diphase blood culture flask is improved, and makes consumption minimizing, judgement convenience, the recall rate of solid medium high.

The utility model comprises bottle, bottle cap, and bottle cap is spun on the bottleneck of bottle, it is characterized in that: be provided with partition on the side in bottle, solid medium stick to cut off in the bottle and bottleneck between the side on.During use, add solid medium (adding developer in the nutrient culture media) on partition in empty bottle and the side between bottleneck earlier, solid medium is sticked on this side, blood sampling is gone into bottle through the cultivation of uniform temperature, time then, then can see through bottle and observe that change in color has judged whether bacterial growth on the solid culture basal plane.

The utility model is owing to set up partition on original structure, make the solid medium consumption that sticks in the bottle reduce more than 70%, and in solid medium, can add developer, make to have judged whether that bacterial growth becomes very convenient, improve 2 to 3 times than conventional method through testing its positive rate.The utility model also can be used for the pathogen of various body fluid such as cerebrospinal fluid, hydrothorax, ascites and cultivates.

Specific embodiment:

Provide embodiment of the present utility model and accompanying drawing below, and be described further:

Fig. 1, be front view of the present utility model;

Fig. 2, for cuing open and show view in a left side of the present utility model.

Press Fig. 1, shown in Figure 2, the utility model comprises bottle 1, bottle cap 2, and bottle cap 2 is spun on the bottleneck of bottle 1, be provided with on the side in bottle 1 to cut off 3, solid medium 4 stick to cut off in the bottle 13 and bottleneck between the side on.During use, add solid medium 4 (adding developer in the nutrient culture media) on partition 3 in empty bottle and the side between bottleneck earlier, solid medium 4 is sticked on this side, bottle cultivation through uniform temperature, time is gone in blood sampling then, then can observe 4 last change in color of solid medium through bottle 1 and judge whether bacterial growth.

Claims

1, a kind of diphase blood culture flask, it comprises bottle 1, bottle cap 2, bottle cap 2 is spun on the bottleneck of bottle 1, it is characterized in that: be provided with on the side in bottle 1 and cut off 3, solid medium 4 stick to cut off in the bottle 13 and bottleneck between the side on.
