Description

Novel sampling tube for in vitro diagnosis industry

Technical Field

The utility model relates to a technical field of diagnosis trade, especially a novel sampling tube for external diagnosis trade.

Background

After the pipette that uses at present carries out liquid sampling, the sample will react with the diluent, among the prior art who realizes this function, all want to absorb quantitative sample through the pipette, at this in-process, only adopted certain suction of sampling tube itself, will stop absorbing after absorbing sufficient sample, because of there is not clear and definite instruction sign, the sample that can't confirm to absorb is accurate, absorb the sample after, still need to mix the reaction with sample and diluent through moving the liquid storehouse, need a plurality of complicated steps to accomplish the experiment in whole experimentation.

The other pipette and dropper integrates quantitative sampling and quantitative dropping liquid, the few steps of the experiment are simplified, after sampling, the sampling tube needs to be placed into a reagent tube, a sample and diluent are mixed and react in the pipette, the liquid to be detected is obtained after the reaction is completed, the liquid to be detected is dripped onto test paper to be detected through the dropping liquid tube, in the process, the sample and the diluent are mixed in the pipette, the sample at the pipe orifice of the pipette reacts with the diluent rate first, the sample at the pipe orifice is mixed with more and more diluent after time lapse, the sample far away from the pipe orifice of the pipette is less mixed with the diluent, or due to the pipette, the uppermost sample and the diluent are not mixed at all, and are easily irradiated to be mixed with the diluent unevenly, so that the experimental result has errors.

In summary, the defects in the prior art are as follows:

1. when the test is carried out, more steps are needed, and the test is more complicated.

2. When the test is carried out, the sample and the diluent are not uniformly mixed, so that errors easily occur in the test.

In view of the above, the present inventors have specifically designed a novel sampling tube for in vitro diagnostic industry, and have resulted in this case.
