Abstract
The utility model discloses a blood culturing bottle. The bottom of the blood culturing bottle is a chemical ceptor, the middle of a container is various culture mediums which are suitable for the growth of the microbe, and mixtured gases are arranged in the top face of the culture medium and the interior of the container; a culturing device and an indicating device are combined as one by the culturing bottle, and thus the blood culturing bottle has easy use; the growth situation of the microbe can be observed out of the bottle when culturing the microbe, and bottle-outer continuous measurement can be realized by devices; thus the traditional handwork culturing method can realize automatic measurement; the utility model realizes blood-culturing automation, improves sensibility and shortens culturing time.
Description
[technical field]
The utility model relates to a kind of medical test device, particularly, relates to a kind of blood cultivation bottle.
[background technology]
In the Clinical microorganism laboratory, blood culture is one of a kind of most important and modal test.The patent No. is that the utility model patent of ZL 0229447.8 discloses a kind of blood cultivation bottle, it comprises culture apparatus, indicating device and the web member of sealing, culture apparatus is connected side by side with the indicating device level, and the syringe needle of web member is inserted into below the liquid phase medium liquid level in the culture apparatus by bottleneck.Because culture apparatus, indicating device connect by web member, use and operate all inconveniences.
[summary of the invention]
The utility model technical issues that need to address just are to provide a blood cultivation bottle that culture apparatus and indicating device are integrated, this culture flask is easy to use, can be when carrying out microbe culture in bottle External Observation growth of microorganism situation, realize the outer METHOD FOR CONTINUOUS DETERMINATION of bottle by instrument, make traditional manual cultural method realize measuring automatically.
For addressing the above problem, the technical solution of the utility model is:
The utility model blood cultivation bottle comprises seal bottle cap, sealing culture vessel, and the sealing bottom of culture vessel is a chemocepter, in the middle of the container for being suitable for the various nutrient culture media of growth of microorganism, above the nutrient culture media, internal tank has mixed gas.
Seal bottle cap described in the utility model is double-deck, and internal layer is a rubber plug, and skin is a gland bonnet.
Preferably, chemocepter described in the utility model is the carbon dioxide receptor.Mixed gas described in the utility model is carbon dioxide, hydrogen and nitrogen mixture body, carbon dioxide 15%, hydrogen 5%, nitrogen 80%.Perhaps mixed gas is carbon dioxide and oxygen mixed gas, carbon dioxide 10%, oxygen 90%.
The carbon dioxide receptor of the utility model culture flask bottom is green bromothymol blue.Nutrient culture media in the culture flask is limpid transparency liquid, and contains polymeric adsorbent, but slight muddiness and slight precipitation can be arranged.
The utility model culture flask is used for measuring blood and other aseptic body fluid of doubting to bacterium or fungal infection patient and whether has microorganism.The utility model culture flask provides appropriate nutrition composition and growing environment for microorganism common in the blood.Whether after the culture flask of inoculation sample is put into instrument, cultivate and monitoring continuously, measuring has bacterium and fungi growth.
If there is microorganism in the test specimen, because microorganism carries out metabolism to the material in the nutrient culture media, and produce carbon dioxide, along with microbial growth, carbon dioxide rises, and the carbon dioxide receptor color that the culture flask bottom can see through gas becomes yellow from green.Can utilize chromogen receptor reflected light to come the existence and the production of dissolubility carbon dioxide in the continuous monitoring nutrient culture media by BacT/Alert microbe culture system, determine the microbial growth situation automatically.Also can judge the growth of bacterium by the change color of visual inspection receptor.
Advantage of the present utility model is culture apparatus and indicating device are integrated, and can realize the outer METHOD FOR CONTINUOUS DETERMINATION of bottle by instrument in bottle External Observation growth of microorganism situation when carrying out microbe culture, makes traditional manual cultural method realize measuring automatically.This device can make the blood culture robotization, improves susceptibility, shortens incubation time.
