Abstract
The utility model relates to a blood culture bottle, which comprises a sealed culture device, an indicating device and a connecting piece, wherein the culture device is connected with the indicating device horizontally in parallel; and a needle head of the connecting piece is inserted into the liquid level of a liquid-phase culture medium from a bottleneck. In addition, the indicating device is internally provided with a solid-phase culture medium. The structure adopts the horizontal and parallel connection, the affection of the action of gravity to the sensibility can be weakened, and the indicating sensitivity is improved; moreover, the structure is very simple. Furthermore, due to the design of the solid-phase culture medium in the indicating device, the automatic growing change can be realized, thereby saving time and simplifying operation.
Description
Technical field
The utility model belongs to the Clinical microorganism technical field, is specifically related to a kind of blood cultivation bottle that is used for blood cultivation.
Background technology
At present, the instrument that is used for blood cultivation clinically is more complicated all, mainly contain the ESP automatization culture systems instrument of U.S. Defico company, this culture systems is to utilize the gas that produces gradually in the bacterial growth in the bottle that pressure of the inside of a bottle is raise, injection needles by web member transfers the pressure to pressure transmitter, and this information representation is come out.Its advantage is the level of automation height, and susceptibility is strong, quick in theory.Its shortcoming is: one, involve great expense the maintenance cost height.Two, instrumentation is loaded down with trivial details, needs the professional and technical personnel of special training correctly to use.Three, be that the positive or negative findings all need professional's manual operations inevitably, will have the bottle of bacterial growth to do further transferred species, increase cost to isolate bacterium.In addition, because transferred species can not be carried out automatically, be subjected to the influence in staff's commuter time, the time of causing is delayed, and delays the diagnosis and treatment.Four, instrument returns owing to reasons such as power failure cause reporting by mistake positive findings, can cause mistaken diagnosis.Also having a kind of product in addition is the Singal blood culture system of Britain oxOID company, it is a tubule blood cultivation bottle with indicating unit, the blood cultivation bottle is connected up and down by injection needles with indicating unit, certain position under the liquid level of needle tip insertion substratum, when producing gas in the bacterial growth in the blood cultivation bottle air pressure in the bottle is raise gradually, liquid in the bottle is in the tubule as indicating unit by pressure by injection needles, naked eyes is observed at an easy rate obtained positive prompting.Its advantage is: valency consumption Dui Shi, safeguard easily, and be easy to popularize use in China; Simple to operate, practicality; If there is not positive prompting, then need not remakes further transferred species and handle; Extraneous few in the factor of disturbing.Its shortcoming is: because indicating unit is last, action of gravity weakens its susceptibility; If positive prompting still needs the professional and technical personnel to do further transferred species and separates, not only increase workload but also expend time in.This shows that all there is certain shortcoming in the blood cultivation instrument that uses at present, requires further improvement.
The utility model content
The purpose of this utility model is at the prior art above shortcomings, design a kind of simple in structure, highly sensitive, need not transferred species, blood cultivation bottle easy and simple to handle.
Structure of the present utility model is as follows: the blood cultivation bottle comprises the culture apparatus of sealing, it is characterized in that being connected with indicating unit side by side with the culture apparatus level, and the syringe needle of web member is inserted into below the liquid phase medium liquid level in the culture apparatus by bottleneck.When having bacterial growth to produce gas in the liquid phase medium, the air pressure in the device is raise, in web member is pressed into indicating unit, make naked eyes be easy to observe liquid.The mode of this parallel connection can weaken the influence of action of gravity to its susceptibility, improves display sensitivity, and structure is also quite simple simultaneously.
In described indicating unit, be provided with the solid phase substratum, when bacterial growth bacterium liquid is pressed into indicating unit, the bacterium liquid solid phase substratum of flowing through, thus play the effect of automatic transferred species, save time, simplify the operation.
Therefore, this blood cultivation bottle have simple in structure, display sensitivity is high, easy and simple to handle, save cost and the characteristics of time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1-substratum, 2-culture apparatus, 3-syringe needle, 4-web member, 5-indicating unit, 6-solid phase substratum, 7-clamp.
Embodiment
Referring to Fig. 1, the blood cultivation bottle is made of sealing culture apparatus 2, indicating unit 5 and web member 4.Culture apparatus 2 is connected side by side with indicating unit 5 levels, web member 4 is a soft catheter, the syringe needle 3 of one end inserts in the culture apparatus, syringe needle is positioned at below substratum 1 liquid level, the other end of web member 4 inserts in the indicating unit 5, indicating unit 5 is provided with antipollution breather hole, is provided with the solid phase substratum 6 that is an inclined-plane in the indicating unit 5.For stable, culture apparatus 2 and indicating unit 5 usefulness clamps 7 interfix.
During use, after laboratory technicians was given clinical nurse with the blood cultivation bottle, the nurse used the iodine disinfection bottle stopper, extracted the patients'blood sample, injected in the culture apparatus and sent into the laboratory.Laboratory technicians is with the bottle stopper iodine disinfection of culture apparatus, end with the syringe needle head length of junctor inserts in the bottle then, and the other end inserts in the indicating unit, puts into 35 ℃ of incubators and cultivates, observe every day, if indication has bacterial growth, will observe whether colony growth is arranged on the homophase substratum, if having, then can observe the characteristics of bacterium colony, do dyeing, identify and drug sensitive experiment, to reach the purpose that goes out report fast.
Claims (5)
1. blood cultivation bottle comprises it is characterized in that the culture apparatus (2) of sealing being connected with indicating unit (5) side by side with culture apparatus (2) level, and the syringe needle (3) of web member (4) is inserted into liquid phase medium (1) in the culture apparatus (2) below the liquid level by bottleneck.
