Description
Technical field
The present invention relates to a kind of oscillator for sputum specimen mixing and operation method thereof, belong to medicine equipment and application thereof.
Background technology
In the respiratory tract of people, the same direction towards oral cavity of many ciliolum billowing wheats, slowly releases dirt, and when shifting throat onto, people will cough and spit.Everyone phlegm density is different, and which type of bacterium of the inside all may be carried.If at will disorderly told, after phlegm becomes dry, in phlegm, thousands of bacterium will be waftd in air.The time that these viruses, germ are survived in physical environment is different in size, and what have can survive 6 to 8 months in dry sputum; And the tubercle bacillus in phlegm is wafted with dust, can maintain 8 to 10 days send out vigor.Say to a certain extent, this bad health habit of the popular people of being exactly of SARS causes.Phlegm is exactly the fester in lung in fact, and bacterium is just contained in fester.When people breathe sordid thing, these things through special " process ", finally can be excreted by cough in the respiratory tract of human body.Even if so healthy people, the phlegm that they spue also is sordid.
Sputum is a kind of means of hospital assay disease, and the sputum collected, before process sputum sample, is first put into sputum cup, joined by digestive juice in sputum cup by Hospitals at Present, and dissolve to accelerate it, doctor manually shakes up 10 ~ 15 minutes.For doctor, if sample is too many, this workload is comparatively large, manually rocks and arm can be caused aching and limp, and test solution can not be made to remain on (37 DEG C) within desirable temperature range when shaking up by hand.From application, the object of sputum vibration, be for follow-up sputum smear is prepared, therefore, it is very large whether it mixes subsequent affect.At present, the craft of hospital doctor vibration not only cannot the consistance of definitely sample Blending Efficiency of Blending, and also reduce work efficiency, medical vortex mixer is in the market of a great variety, and for various test solution mixing operation, but the product being specifically designed to sputum specimen mixing does not have.
Summary of the invention
The object of the invention is to overcome existing sputum specimen still adopt when mixing manual rock mixing cannot the consistance of definitely sample Blending Efficiency of Blending, ineffective problem, devise a kind of oscillator for sputum specimen mixing and operation method thereof, this oscillator and operation method thereof alleviate the manual labor intensity of biochemical analysis personnel when testing greatly, by the present invention carry out bulking substances mixing operate the mixing reagent drawn have mixing homogeneity good, process standard is unified, and when adding heating system, can micropopulation in guarantee reagent under the environment being equal to human body temperature by abundant good characteristic such as mixing grade.
Object of the present invention is achieved through the following technical solutions: a kind of oscillator for sputum specimen mixing, comprise the support of inner hollow, holder is provided with directly over described support, motor is provided with in support, motor is connected with central rotating shaft, and central rotating shaft is connected with holder, and described central rotating shaft outer setting has at least three group bracing or strutting arrangements, bracing or strutting arrangement is evenly distributed between support and holder centered by central rotating shaft, and the two ends of bracing or strutting arrangement are connected with support and holder respectively.
In technique scheme, the pallet that holder comprises reagent plate rail and is arranged on below reagent plate rail, the bottom of reagent plate rail is fixed on pallet, reagent bottle is placed on pallet, the sidewall of reagent bottle carries out contact by reagent plate rail to be fixed, central rotating shaft is connected with the bottom of pallet, the bottom of the pallet of bracing or strutting arrangement connects, it is varied that mixing for the vortex mixer of other test solutions realizes principle, pivotal blending manner is adopted to be commonplace, its shortcoming is that mode of motion is single, test solution under inertia effect with inboard wall of test tube geo-stationary, Blending Efficiency of Blending is had a greatly reduced quality.Motor is utilized to provide power by the present invention, central rotating shaft is carrying out support rotating, simultaneously by increasing some bracing or strutting arrangements in the surrounding of central rotating shaft, form the system provided support pallet during the axis of rotation of center, bracing or strutting arrangement is at least three groups, and the line of bracing or strutting arrangement forms a polygon, and central rotating shaft is arranged on this polygonal center, make pallet when rotating, operationally this mechanism can guarantee that pallet does flatness and reciprocator vibrations, and self can not irregularly rotate.Ensure the rotation direction of pallet, the reagent in the reagent bottle be placed in reagent plate rail stably in regular, can mix by the rotation direction of pallet.
