Description

Technical Field

[0001] The utility model specifically relates to the field of blood collection tubes, and in particular to a blood collection tube packaging device. Background Art

[0002] The principle of vacuum blood collection tubes is to pre-draw different vacuum degrees into the blood collection tube with a head cover, and use its negative pressure to automatically and quantitatively collect venous blood samples. After one end of the blood collection needle is inserted into the human vein, the other end is inserted into the rubber stopper of the vacuum blood collection tube. The human venous blood is drawn into the blood sample container through the blood collection needle under the action of negative pressure inside the vacuum blood collection tube. In one venous puncture, multiple tubes can be collected without leakage. The inner cavity volume connected to the blood collection needle is very small, and the impact on the blood collection volume can be ignored, but the probability of backflow is relatively small. If the inner cavity volume is large, it will consume part of the vacuum degree of the blood collection tube, thereby reducing its collection volume.

[0003] When packaging vacuum blood collection tubes, the existing packaging device needs to extract and package the caps reciprocally, and the caps can only be extracted and packaged after the previous vacuum blood collection tube is packaged. The packaging takes a long time and the packaging efficiency of the vacuum blood collection tubes is low.

[0004] Therefore, we propose a blood collection tube packaging device to solve the above problems. Utility Model Content
