Abstract
The invention discloses a blood culture bottle with a positive alarm device. The bottle comprises a bottle body for containing a blood sample and a bottle cap arranged on the mouth of the bottle body in a seal manner, the top of the bottle cap is provided with a trigger alarm, and a pressure trigger assembly for controlling the conduction of the trigger alarm is arranged in the bottle cap. The pressure trigger assembly is a slide block capable of moving up and down along the inner sidewall of the bottle cap; and a flexible protection film in sealed connection with the inner sidewall of the bottle cap is also arranged between the trigger alarm and the slide block in order to prolong the service life and avoid pollution. The blood culture bottle with the positive alarm device has the advantages of simple structure, small size, easy handling, complete functions, easy manufacturing and low production cost.
Description
Technical field
The present invention relates to medical correlative technology field, especially relate to a kind of Blood culture bottle with positive warning device.
Background technology
Current hemoculture mode has two kinds, and one is that artificial culture is observed, and one is undertaken by full-automatic Blood culture system.Need observe every day when manually carrying out hemoculture, and take Continuous Observation 7 days, not only labor intensive and the time, and hemoculture result is positive or feminine gender judgement with operator and operating experience difference and change to some extent, stdn, accuracy are poor.Full-automatic Blood culture system is made up of Blood culture bottle, pertinent instruments and software, its principle is by constantly producing carbonic acid gas in bacteria growth process, by arranging light source or form reflected light bottom Blood culture bottle, utilize gas concentration lwevel variable effect change in optical signal, after instrument and software process automatically, obtain cultivation results.In actual application, the change on the one hand due to optical signal is more by external influence factor, and software carries out analyzing and processing by the change of optical signal, so the unstable of optical signal very easily causes software processes mistake, forms false positive warnings; On the other hand owing to using optical signal, need to install optical flame detector at bottle bottom, complicate fabrication process, higher manufacturing cost makes toxigenic capacity also very high.
Summary of the invention
The invention provides a kind of Blood culture bottle with positive warning device, cultural method is easy and cultivation results is more directly perceived, there will not be the phenomenon of the false sun of report.
For achieving the above object, the present invention can take following technical proposals:
Blood culture bottle with positive warning device of the present invention, comprise the bottle for holding blood sample and seal the bottle cap be arranged on bottle body and bottleneck, described Bottle cap top is provided with trigger-type alarming device, is provided with the pressure activated assembly controlling the conducting of described trigger-type alarming device in described bottle cap.
Described pressure activated assembly is the slide block moved up and down along described bottle cap inner side-wall; For extending its work-ing life, avoiding polluting, the flexible cuticula be tightly connected with described bottle cap inner side-wall can also be provided with between described trigger-type alarming device and slide block.
Described pressure activated assembly can also be seal the metal clips be arranged on described bottle cap inner side-wall.
Described trigger-type alarming device is with pilot lamp and hummer.
Blood culture bottle with positive warning device provided by the invention, structure is simple, and small and exquisite nimble, function is complete, is easy to manufacture, and production cost is low.Utilize the change of pressure carbon dioxide in Blood culture bottle to make pressure activated assembly connect warning circuit thus produce positive warning, efficiently solving the problem of false positive warnings in hemoculture process.Blood culture bottle used in the present invention no longer needs to install optical flame detector, eliminate change in optical signal and be subject to the flase alarm that various factors produces, do not need to use complicated software system to analyze the optical signal of change yet, by means of only the change of pressure of the inside of a bottle, direct connection guard signal, the result obtained is more directly perceived, more accurately.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention 1.
Fig. 2 is the enlarged view in A portion in Fig. 1.
Fig. 3 is the structural representation of the embodiment of the present invention 2 covering part.
Fig. 4 is the structural representation of the embodiment of the present invention 3 covering part.
Embodiment
Embodiment 1:
As shown in Figure 1, 2, Blood culture bottle with positive warning device of the present invention, comprise the bottle for holding blood sample and seal the bottle cap 1 be arranged on bottle body and bottleneck, be provided with the trigger-type alarming device 2 with pilot lamp and hummer at bottle cap 1 top, be provided with in bottle cap 1 and move up and down slide block 3 for controlling the conducting of trigger-type alarming device along bottle cap 1 inner side-wall.
During use, if be placed in blood sample to be cultivated in Blood culture bottle to there is bacterium, in culturing process, bacterium can in bottle growth metabolism, in bottle, amount of carbon dioxide increases, and makes the pressure increase in culturing bottle, and slide block 3 moves up to push up along bottle cap 1 and presses trigger-type alarming device 2 to make pilot lamp and buzzer warning under the promotion of carbon dioxide, point out this blood sample to be positive, the operation carrying out next step can be taken out; If do not have bacterium in blood sample, the pressure in culturing bottle is constant, then slide block 3 upwards can not push up pressure trigger-type alarming device.Culturing process is simple, and cultivation results is directly perceived, there will not be erroneous judgement.
Embodiment 2:
The warning howler of pollution bottle tops during for avoiding blood sample positive, the present invention's pressure activated assembly used also can adopt following structure (rest part is with embodiment 1), as shown in Figure 3, between trigger-type alarming device 2 and slide block 3, be provided with the flexible cuticula 4 be tightly connected with bottle cap 1 inner side-wall.This flexible cuticula 4 can be made up of the flexible materials such as silica gel, rubber, for isolating between trigger-type alarming device 2 and bottle inner blood sample, keeping trigger-type alarming device 2 to be in free of contamination environment, extending the work-ing life of trigger-type alarming device 2.
Embodiment 3:
During actual fabrication, the present invention's pressure activated assembly used can also adopt following structure, as shown in Figure 4, on bottle cap 1 inner side-wall, sealing is fixed with metal clips 5, when pressure carbon dioxide in bottle raises, metal clips 5 central compression pops up, pressing trigger-type alarming device 2, make pilot lamp and buzzer warning, indicate this hemoculture to be positive.Or this metal clips 5 self as switch, when popping up under gas push, can make the circuit ON of trigger-type alarming device 2, makes it send signal.
