Technical Field

The invention relates to the technical field of medical examination collection devices, in particular to a blood collection device for medical examination.

Background

Currently, medical tests are often used to identify a person's blood type, determine whether a person is anemic and has normal liver function, and the like. Blood collection and testing are common medical testing methods, and blood collection is often required in blood routine detection. The collection tube is typically used to withdraw blood by puncturing a finger with a lancet and squeezing the finger.

However, the finger pricking process is dependent on personal experience, and if the finger pricking process is too deep, the patient is easy to feel more pain; the blood sampling needle puncture finger and the collection tube draw blood separately, and blood easily flows off from the finger to the ground after the blood sampling puncture finger and before the blood collection tube draws blood, so that pollution and waste are caused; in addition, the blood sample after blood collection is easy to flow out of the collection tube, which also causes waste.

In view of this, the present invention provides a blood collection device for medical testing.
