Embodiment
A kind of closed extraction PRP evacuated blood collection tubes, are made up of, plug 2 is encapsulated in former pipe 1, plug 2 and protective cap 3
The mouth of pipe of former pipe 1, protective cap 3 wraps to be evacuated in the outside of plug 2, former pipe 1；The tube wall of former pipe 1 is provided with a tube wall opening 4, pipe
Wall opening 4 is closed with tube wall rubber cushion 5；The bottom of former pipe 1 is provided with blood separating colloid 9, and blood separating colloid 9 is provided with anti-coagulants above
10。
Another closed extraction PRP evacuated blood collection tubes, by rubber linking tube 6, upper tube 7, down tube 8, plug 2 and protect
Helmet 3 is formed, and plug 2 is encapsulated in the mouth of pipe of upper tube 7, and protective cap 3 is wrapped in the outside of plug 2, the other end and rubber linking tube of upper tube 7
6 connections, the other end of rubber linking tube 6 are connected with down tube 8, are formed a stage casing and are the test tube of rubber tube, and are pumped into true
It is empty；The bottom of down tube 8 is provided with blood separating colloid 9, and anti-coagulants 10 is provided with above blood separating colloid 9.
Another closed extraction PRP evacuated blood collection tube, is made up of, the envelope of plug 2 former pipe 1, plug 2 and protective cap 3
