Description
Technical field
The utility model embodiment is related to blood sample acquisition technique field, and in particular to a kind of finger tip blood-taking device.
Background technique
Blood assay techniques have become the important evidence of medical diagnosis on disease, especially for gene diagnosis field, more have
Very important status.End capillary blood sampling due to its blood sampling volume is few, conveniently the advantages of, be applied to micro-
Amount detection or the blood collection to child, especially blood glucose etc. monitor field.With the continuous development of medical technology, end capillary
Blood vessel blood collecting technology also can predictably be widely used in blood sample acquisition.
However, the common way of existing capillary blood sampling is that medical staff holds blood taking needle directly to finger finger tip
It is punctured, before finger tip blood sampling, although there is opponent's fingering row simply to disinfect, is had to wait for after disinfectant is completely dried
It can just carry out puncturing blood sampling, in waiting process, finger may be by tissue fluid or air pollution；Moreover, after puncturing bleeding, it cannot
Blood sample acquisition is carried out in time, causes blood sample contaminated.Sometimes, for some high-precision gene diagnosis engineerings, this
Kind pollution often brings more serious consequence.
Utility model content
For this purpose, the utility model embodiment provides a kind of finger tip blood-taking device, with solve in the prior art due to disinfection after
Blood sample is contaminated caused by blood sample cannot be acquired after cannot puncturing or puncture in time in time, and gene diagnosis is caused to miss
The problem of difference.
