Description

Technical Field

[0001] The utility model relates to the technical field of child soothing equipment, in particular to a blood sampler. Background Art

[0002] At present, venous blood sampling is a common blood sampling method. Although the existing blood sampler is equipped with a needle protection cover at the venous puncture end, medical staff need to put a needle protection cover on the needle during the venous blood sampling of the subject. If the subject is an AIDS carrier, the needle used for blood sampling may injure the medical staff, resulting in the risk of AIDS infection.

[0003] Currently, the blood samplers on the market have the following disadvantages:

[0004] (1) Existing blood samplers lack a protective mechanism. Medical staff wear a needle tube protective cover during venous blood sampling, which makes it difficult to align the needle tube protective cover. The operation requirements are too high, resulting in low work efficiency of medical staff;

[0005] (2) Existing blood samplers lack a storage mechanism. After medical staff collect samples, the used needles need to be disposed of. Traditional needle tube protective covers are easily damaged during transportation and are not easy to warn.

[0006] Therefore, the utility model provides a blood sampler. Utility Model Content
