Technical Field

The invention relates to a full-automatic test tube capping device and a cap taking device.

Background

Blood examination is one of the most common test contents in hospitals, and body abnormal conditions such as human anemia, diabetes, various infections, blood diseases and the like can be determined through blood analysis and detection, so that a patient is informed of many details about health conditions. Disposable vacuum negative blood sampling tubes are frequently used blood sampling tools in hospitals today. Before the blood sample collected by the vacuum blood collection tube is sent to a test chamber for analysis, the vacuum blood collection tube is generally subjected to centrifugation, decapping and other treatments to obtain serum or plasma for on-machine test. Currently, the uncapping of blood sample tubes is still manually opened by the staff. The manual decapping operation has the risks of scratching operators due to the rupture of a test tube port, splashing blood and generating blood aerosol in the decapping process, and particularly, the blood of some patients has infectivity, so that the virus in the blood easily infects workers. In addition, the manual opening of the lid of the vacuum blood collection tube is a mechanically repetitive, tedious and laborious task for the operator, facing a large number of blood samples each day.
