Clostridium difficile is the microorganism that a kind of pure anaerobism cultivates one's ability and grows, and its disease causing causes exceedance ten thousand deaths every year America and Europe, and has the extra medical expense over multi-million dollar.At present, the detection of clostridium difficile at home hospital is not yet universal, and its reason is mainly that condition of culture is harsh, and positive rate is low, and detection method is more loaded down with trivial details.After excrement sample sampling, directly inoculation clostridium difficile selective medium positive rate is lower, research discovery, and by after excrement sample and absolute ethyl alcohol hybrid processing, then inoculation, positive rate can improve greatly.
The sampler of current clinical use is mainly plastic cup with cover, has a little spoon for picking excrement sample in cup.Its consumption is extensive, and price is also cheap, but has many defects, can not perform well in sampling and the censorship of clostridium difficile.The first, such spoonful of shape sampler can only the rare soft stool of picking, can not picking watery stool, and C. difficile infection patient, usually row's is watery stool, mucoid stool or mucous bloody stool, particularly for the clouded in mind patient who lies in bed, what usually use is stern pad, and patient defecates and directly comes on stern pad, samples more difficult; The second, doing stool routine examination inspection needs in a small amount, but during for other inspections or scientific research, as the DNA that extracts the pathogenic microorganism in the stool molecular biology identification of doing pathogenic bacteria is when check, need the slightly stool of volume, therefore the more watery stool of picking is more difficult, and the aspirator of syringe-type has just in time solved this problem; Three, excrement sample is directly inoculated clostridium difficile CCFA selective medium; cultivate positive rate not high; after picking sample and absolute ethyl alcohol hybrid processing, can obviously improve positive rate, but this also has two loaded down with trivial details steps, first picking sample is to microcentrifugal tube; usually can pollute tiny tube wall; and be not easy picking, consuming time, secondly; in microcentrifugal tube, add after absolute ethyl alcohol sample to condense agglomerating, need to use oscillator just can mix.And be furnished with absolute ethyl alcohol memotron, can save above-mentioned two steps with this device that mixes beaded glass, experiment is become simply, be easier to operation.
Utility model content
The utility model, for the problems referred to above, provides a kind of C. difficile infection sample sampling pre-service mixing arrangement simple to operate, easy to use, multi-functional.
The utility model is realized by the following technical solutions:
A kind of C. difficile infection sample sampling pre-service mixing arrangement comprises storage bottle and sampler, it is characterized in that: described storage bottle is built-in with beaded glass, on storage bottle screw top closure, be provided with ethanol reservoir, with the sampler of aspirator and sampling spoon, one end that described sampler is provided with aspirator and sampling spoon is placed in storage bottle bottle, and the tip of suction tube and the concave panel of sampling spoon are positioned at the same side.
Described storage bottle is cylindrical bottle, and its bottle of inner bottom part is placed with beaded glass, and when jiggling, beaded glass can be conducive to absolute ethyl alcohol and sample mix is even.
Described ethanol reservoir is the graduated dropper of a round end band, can be used for storing absolute ethyl alcohol, and can control by scale the addition of absolute ethyl alcohol.
Described suction tube is connected with suction cylinder, in suction cylinder, is provided with piston, is fixed with sucker rod on piston, and when sucker rod outwards stretches, sample can enter in suction cylinder by suction tube, after sampling, again water sample excrement sample is injected to storage bottle.
The beneficial effects of the utility model are: this C. difficile infection sample sampling pre-service mixing arrangement is simple in structure, not only conveniently makes a collection of specimens but also avoid sample to pollute, and can also carry out the pre-service before sample cultivation simultaneously.Its mode that adopts aspirator and sampling spoon to combine is left and taken excrement sample, if get rare soft stool, only needs the sampling spoon picking on operative installations to defecate in right amount, if just water sampling can be used suction means to collect.This C. difficile infection sample sampling pre-service mixing arrangement is easy to use when gathering or detecting stool sample, be convenient to adding of absolute ethyl alcohol, and can carry out mixing of sample and absolute ethyl alcohol, be conducive to improve clostridium difficile and cultivate positive rate, avoid contaminated environment, alleviated medical worker's work difficulty.
