Technical Field

The invention relates to the technical field of collection devices, in particular to a portable blood sample collector and a using method thereof.

Background

Blood is a red opaque viscous liquid that flows in human blood vessels and the heart. The blood consists of plasma and blood cells, wherein one liter of the plasma contains 900-910 g of water, 65-85 g of protein and 20 g of low molecular substances, the low molecular substances contain various electrolytes and organic compounds, and the blood cells comprise three types of cells, namely red blood cells, white blood cells and platelets; clinical blood tests can be divided into general blood tests, laboratory tests for hemolytic anemia, cytological tests for bone marrow, blood grouping and cross matching tests. Hematological signs of common hematological disorders can be detected.

But current portable blood sample collector, mostly adopt needle tubing or collection sword when the doctor is gathered, the direct push-and-pull pressure of its needle tubing can give people and bring huge pain, collection system can not reach good result of use, secondly, after the doctor collection finishes, because can remain people's blood in the collection instrument, and because doctor's sample device is most less, probably lead to blood to flow out when placing the sample, lead to people's sample can not obtain complete sterile treatment.

Disclosure of Invention
