Description

Blood collection tube batch cap remover

Technical Field

The utility model relates to the technical field of medical instruments, in particular to the field of clinical examination medicine and biological basic scientific research experimental devices, and specifically relates to a batch cap remover for blood collection tubes.

Background

The blood collection tube is a vessel for drawing out blood during examination. In clinical tests, different test items have different requirements on blood samples, including whole blood, serum and plasma, and different blood collection tubes are required to be matched and applied. Different blood collection tubes typically correspond to different test items. Red is used for routine serum and biochemical examination, orange is used for emergency serum test, green is used for erythrocyte fragility test and the like, purple is used for blood routine examination, and black is used for blood sedimentation and the like; the blood collection tube has extremely large usage amount and can be widely applied to clinical blood detection.
