Description

technical field [0001] The invention relates to a connecting device for blood sample collection. Background technique [0002] After the blood is collected, it is put into a sealed blood bag. The blood bag has an external interface and a specimen hose. The blood sample in the specimen hose is sealed by a heat sealing machine and separated into two sections, which are also sealed. The requirements are very low. Strict screening is required after blood collection to ensure blood safety before it can be supplied to the clinic. Therefore, during the screening process after blood collection, the blood sample in the specimen tube needs to be taken out for screening. The current blood bank method is to directly cut off one end of the sealed hose and squeeze the blood sample into the test tube. However, because the sealed hose is very thin, even if the two ends are cut, the blood sample will not flow down automatically. Squeezing may destroy blood components, and blood samples may ...
