Description

Clinical Laboratory hemoculture device

This utility model relates to a kind of Clinical Laboratory hemoculture device.

Hemoculture is one of content of Clinical Laboratory, and at present, prior art is after extracting blood samples of patients, injection fills and increases bacterium in the culture bottle of fluid medium and cultivate, and through 12-18 hour 35 ℃ hatch after, on the solid plate culture medium, blindly propagate once, to detect positive sample ahead of time.After blindly propagating, cultivate and hatch, observe whether positive the sign is arranged every day to 7 days.Though middle blindly propagating can detect positive sample ahead of time, also increased the chance that specimen is polluted.As meeting the situation that the patient has used anti-infection drug, general processing method is to select suitable antagonist for use, or increases the ratio of culture medium, or drug withdrawal treats that getting blood examination again after the drug metabolism tests.Run into this situation, can reduce positive rate greatly, increased the painful and dangerous of patient simultaneously.Antagonist is extremely limited, and most anti-infection drugs there is no effective antagonist, and with the method that increases culture medium, has also diluted the microorganism that may exist in the dilution anti-infectives, and recall rate is reduced.From culture bottle, take a sample in the incubation and propagate, except that operation is loaded down with trivial details, also easily cause the pollution of culture in the culture bottle, influence detecting of infectious bacteria.

The purpose of this utility model provides and a kind ofly can reduce opportunities for contamination, improves recall rate, Clinical Laboratory easy and simple to handle hemoculture device.

The purpose of this utility model is achieved in that a kind of Clinical Laboratory hemoculture device, its profile is a square bottle, the middle part is provided with through hole at the bottom of bottle, microporous filter membrane, sieve plate and funnel are equipped with successively near the through hole face in the side under bottle, on the outlet of funnel, Capsule is housed, on two corresponding sidewalls of a side arm of close bottle, be provided with inside vertical projection, plug be housed at bottleneck.

The wall of bottle extends and forms a bin that holds funnel to the bottom.

Close on both sides on the bottle wall medial surface of projection and can also be provided with one deck solid medium.

The bottle end, also can bevel.

Below in conjunction with drawings and Examples this utility model is further described:

Fig. 1 is the structural representation of embodiment 1 of the present utility model.

Fig. 2 is the structural representation of embodiment 2 of the present utility model.

Fig. 3 is the A-A cutaway view of Fig. 2.

By embodiment shown in Figure 11 as can be known, its profile is a square bottle, the middle part is provided with through hole 3 at the bottom of bottle, microporous filter membrane 4, sieve plate 5 and funnel 2 are equipped with successively near the through hole face in the side under bottle, Capsule 1 is housed on the outlet of funnel, on two corresponding sidewalls of a side arm, be provided with inside vertical protrudingly 6, plug 7 be housed at bottleneck near bottle.

The wall of bottle extends and forms a bin that holds funnel to the bottom.

Close on both sides on the bottle wall medial surface of projection and be provided with one deck solid medium 9.

By Fig. 2, embodiment 2 shown in Figure 3 as can be known, it its a bottle end is the inclined-plane as different from Example 1.

The operational approach that use this utility model carries out hemoculture is as follows:

Before the use, make it airtight with Capsule the funnel outlet, make culture bottle clean also with suitable method sterilization.Under aseptic condition, C faces down with culture bottle, horizontal positioned, again the solid medium that melts is joined in the culture bottle, after treating that solid medium solidifies, add and contain the sterile saline of anticoagulant in right amount or add fluid medium 10, bottle stopper beyond the Great Wall as required, and with enclosing cover locking, can be standby.Above preparation both can realize also can carrying out in laboratory with good conditionsi when producing in batches., get two culture bottles and do aerobe and anaerobic culture respectively when doing hemoculture clinical.Behind sterilizing syringe extraction patient blood, by syringe needle thorn seep through plug 7, blood is injected in the bottle, extract syringe needle, jog makes blood and anticoagulant mixing, prevents blood coagulation.Culture bottle is taken back laboratory, take off the Capsule that is enclosed within on the funnel outlet, allow culture bottle tilt to place (when using embodiment 2), the microporous filter membrane level with the method for malleation (as passing through peristaltic pump) or negative pressure (as passing through vacuum pump), is injected the antimicrobial component of sterile saline filtering serum, Capsule on the funnel outlet beyond the Great Wall subsequently, inject fluid medium, after making fluid medium and filter membrane contacting, cultivate.Under plug, insert air filter 8, make in the air to be interlinked to the outside, but airborne microorganism can not enter.The aerobe culture bottle is placed in the general incubator and cultivates.The anaerobic culture bottle is placed in CO2 gas incubator or other anaerobism incubators and cultivates.After cultivating certain hour, the culture bottle that can reverse makes fluid medium contact with solid medium to propagate.The D face of culture bottle below during cultivation.

Solid or fluid medium difference in the culture bottle can reach different check purposes.

The utility model has the advantages that because of culture bottle is equipped with microporous filter membrane, the filtering interfering thing has improved recall rate effectively.And surface culture medium and fluid medium are in same culture bottle, and above-mentioned blindness is propagated or the purification cultivation is all carried out in same culture bottle, has reduced opportunities for contamination, has simplified operation.Also alleviated simultaneously patient's misery.Because this utility model is a closed system, and is therefore less demanding to environment for use, is suitable for using under medical institutions at different levels and the various condition.For clinical microbiology check provides a kind of better, more efficient methods and apparatus.
