Description
One, technical field
The present invention relates to a kind of liquid sample processing device, particularly a kind of liquid sample collection, reagent store and with the two mix, the device of mixing, belong to the liquid sample processing device technical field of structures.
Two, background technology
(Point-of-Care Testing POCT), claims other check of bed or POCT again to real-time test, has the advantage that assay is offered immediately the doctor.And traditional laboratory detection need be delivered to the laboratory with the sample of gathering, and waits for that several hours time to several weeks could send the result to doctor.
Have only that operation steps is few, method of operating is simple, be easy to learn and use, and does not need the large automatic instrument to handle, and can become the real-time test project by the project of amateur docimaster such as nurse or patient oneself completion.
Large automatic instrument detecting sample is used in the laboratory basically now, need not artificial the intervention.Before self-reacting device was widely used, a lot of test items were accomplished by manual work, and such method is still being used in some small test chamber now.Manual detection sample complex steps needs to operate through the docimaster of special training.As detect the glucose in the blood; Drawing sample with micro sample adding appliance earlier joins in the reaction cup; Sample of every absorption need be changed the suction nozzle of sample injector to avoid cross pollution, draws the first component reagent in reaction cup with sample injector then, sways mixing; Draw the second component reagent with sample injector again and add in the above-mentioned reaction cup, detect with photometer after swaying mixing once more.Some detectable is a dry powder for another example, need add quantitative water or reagent before use and process working fluid and can use.Obviously so complicated operations has limited the application of a lot of test items in real-time test.
