Description
Technical field
The present invention relates to a kind of medicine sample testing apparatus, are filled more particularly to a kind of sampling that medicine sample detects automatically
It sets.
Background technology
The detection of excrement sample, it is used at present square such as the chemical detection of stool routine examination detection and part excrement sample
Method is all relatively backward.From sample collect sample operation inspection and last sample liquid waste processing easily causes environment
With the pollution in laboratory.And the prevalence in order to keep off infection, the cotton swab for the collect specimen that patient is used, the object for holding sample
Product will carry out specially treated, and the link of processing is more, and the probability polluted is higher, in checking operating process, also very
It is unhygienic.With the progress of medical diagnosis and treatment technology, basis checks the necessary links for having become the diagnosis state of an illness.Three is big conventional
One of excrement detection, requirements at the higher level also proposed to detection efficiency, accuracy, resulting number and working environment.Bulletin
Number a kind of automatic detection instrument for excrement sample is disclosed for the Chinese invention patent of CN101487845B, it includes with lower part:From
Movement controller;Dilution device, for quantitative dilution to be added into excrement sample;Stirring and evenly mixing device, for after diluting
Excrement sample stirs and evenly mixs;Detection unit, for being detected to excrement sample;Sample and cleaning device are inhaled, pipeline and institute are passed through
It states detection unit to be connected, for conveying excrement sample to detection unit, and cleans detection unit and connection after detection
Pipeline.And the Chinese invention patent that notification number is CN104049095B discloses a kind of excrement detector, it includes pedestal, gantry
Frame component, Automatic-feeding component, sample conveyer system including chuck component, Suction cup assembly, the first liquid-adding device, the second liquid feeding
Device, the first photographic means, the second photographic means, identification and record system, electric control system and upper layer human-computer interaction are answered
Use software.Excrement detector coordinating operation under the allotment of control system is fully automatically completed to promote, take from the automatic of sample
Sample applies sample, microphotograph, occult blood reaction photograph and recycles whole process automatically, and carried by upper layer human-computer interaction application software
For testing result.For another example the Chinese invention patent that notification number is CN104897911B discloses one kind and being automatically brought into operation stool examination
Instrument.It includes the biomicroscope being fixed on the chassis, sample sampling device, special inspection two way slide lane, special checking device, glass
Sheet devices, Five-channel sampling probe and Y-direction Z-direction manipulator, can automatic sampling, film-making, it is automatic to clean, automatic interpretation spy inspection as a result,
The automatic special inspection consumptive material of recycling, microscope automatically scanning, auto-focusing, automatic lock image, selectivity are left and taken photo information, are printed
Picture and text survey report.The above-mentioned prior art has made favorable attributes to detecting automatically, but also increases answering for equipment mechanism simultaneously
Polygamy substantially increases the cost of device, and detection device is made to be difficult to popularize, and is unfavorable for improving existing complete using manual operation
Defect.The problem of especially above-mentioned prior art has ignored detection device self-pollution or the pollution in order to reduce itself
The complexity for increasing to degree apparatus structure, increases unnecessary cost.As the excrement sample of CN101487845B is examined automatically
It surveys instrument to need to clean sampler after sampling, not only mechanism is complicated, and process is loaded down with trivial details, and cleaning can not have completely
Effect solves the problems, such as self-pollution or sample cross contamination.And the excrement detector of CN104049095B then need one it is dedicated
Sample kit carrys out the problem of solving device self-pollution, causes the use cost of device to increase, keeps popularization and application more unfavorable.
