Description

Sampling bottle

Technical field

The utility model relates to field of medical article technology, more particularly to a kind of sampling bottle.

Background technique

With the development of science and technology, the raising of existing medical level increasingly, existing hospital diagnose the treatment of patient When generally use common detection methods, pattern detection is carried out to determine patient by blood to patient, urine or excrement Physical condition.Sample conventional detection (physics microscopy) generallys use cervical arthroplasty at present, and sample such as excrement etc. need to be exposed to It is observed on microscope carrier, causes to influence working environment.In addition, the state of an illness for patient is different, it is also necessary to patient Sample carries out some necessary chemical detections, such as the detection of fecal occult blood etc., to make accurate diagnosis, people to patient Work is comparatively laborious when detecting, therefore existing copra analysis instrument automatic detection mode is increasingly used by the concern of hospital.

Copra analysis instrument can not only carry out physics microscopy, but also can carry out chemical detection, substantially increase detection work effect Rate alleviates the workload of reviewer.And sampling bottle used in instrument solve present in detection process disinfection trouble, And pollution problem between operation tool and air.Sampling bottle used by existing copra analysis instrument is usually by bottle body, bottle cap It is formed with the partition with filter screen, bottle body is divided into two cavitys with mixed function and sampling functions, bottle body by partition It mainly include sampling cavity and mixing chamber, in use, Stirring mixing is carried out in mixing chamber by the sample after acquiring, with Make sample can be by entering in sampling cavity with filter screen filtration.The impurity in sample is in mixing chamber at this time, and is acquired Sample enter in sampling cavity through filter screen so that copra analysis instrument can carry out sample from the sampling cavity of sampling bottle Acquisition.

However.When existing sample is stirred the process of mixing in mixing chamber, easy pair of the sample impurity in mixing chamber Filter screen results in blockage, so that sample enrichment degree of the sample mixing unevenly and in sampling cavity in mixing chamber be not high Problem.

Utility model content

Based on this, the purpose of this utility model is that proposing a kind of sampling bottle, solves sample in existing sampling bottle and be enriched with journey Spend not high problem.

The utility model provides a kind of sampling bottle, and specific technical solution is as follows:

A kind of sampling bottle, including bottle body, the bottle cap to match with the bottle body top opening, the sampling bottle further includes setting Sampling component and filter assemblies inside the bottle body, one end that the top of the bottle cap corresponds to the sampling component are set There is perforative intercommunicating pore, one end that the top of the bottle cap corresponds to the filter assemblies is equipped with blind hole, and the sampling component includes Rotation section, mixing part and the acquisition portion being set in sequence, the rotation section are used for and the bottle body through the intercommunicating pore The mixing part and the acquisition portion is driven to be rotated after external instrument connection, the filter assemblies include that one end connects jointly It connects, and the first filter plate, the second filter plate, third filter plate and the fixed plate that the other end sorts in the direction of the clock, it is described First filter plate, second filter plate, the third filter plate are equipped with filter screen, in use, the sampling component will be adopted The sample of collection is placed in the bottle body and is enclosed in accommodating area far from one end of the filter assemblies, and carries out rotation stirring, So that the sample stirred evenly in the accommodating area first filter to second filter plate, the third filter plate with it is described Bottle body is enclosed transition region, and then filters and be enclosed to first filter plate, second filter plate with the bottle body Enrichment region, to be enriched in the enrichment region.

Sampling bottle provided by the utility model can be acquired sample by the sampling component of setting, and be placed in In bottle body, to be stirred by rotation to sample, sample is stirred evenly, reduces sample since stirring unevenly makes Need in its sample acquisition substance can not Extraction and enrichment the problem of, while by the setting of filter assemblies, so that its bottle-shaped At the accommodating area for accommodating and stirring sample, for making sample carry out the transition region of impurity prefiltration, and for smart mistake The enrichment region of sample to be collected is enriched with after filter.By the stirring of sampling component so that forming a fixed flow direction in bottle body when using Runner and sample stirring it is uniform, the sample in accommodating area is by the way that after the filtering of third filter plate, more big impurity is protected at this time It stays in accommodating area, filtered sample and a small amount of impurity are in transition region at this time.Pass through the recycle stream for fluid It is dynamic so that the sample in the transition region is enriched in enrichment region after the filtering of the second filter plate, and remained in transition region from The impurity filtered in third filter plate, wherein the first filter plate is used to provide the flow direction of circulation, therefore the application inside bottle body Sample needed for a large amount of samplings can be enriched with out in the enrichment region of bottle body, it is not high to solve sample enrichment degree in existing sampling bottle The problem of.

In addition, can also have the following additional technical features: according to sampling bottle provided by the utility model
