Description
Technical Field
The utility model belongs to the technical field of the heparin tube, concretely relates to human vein procoagulant heparin tube of disposable.
Background
The principle of the vacuum blood collection tube is that a blood collection tube test tube with a head cover is pre-pumped into different vacuum degrees, venous blood samples are automatically and quantitatively collected by utilizing the negative pressure of the blood collection tube test tube, and one end of a blood collection needle penetrates into a vein of a human body and then the other end of the blood collection needle is inserted into a rubber plug of the vacuum blood collection tube. Human venous blood is inside the vacuum test tube, under the effect of negative pressure, through blood taking needle suction blood specimen container, under a venipuncture, can realize that multitube gathers and does not take place to leak. The serum separating gel is a semi-solid inert gel composed of several compounds, and is made up by adopting medical high-molecular material, after the blood is collected and centrifuged, it can be separated into serum (upper layer), serum separating gel (middle layer) and blood cell (lower layer). The thick layer of serum separation gel in the middle of the test tube can completely isolate serum and blood cells, so that the blood cells can not contact the serum, thereby ensuring the purity of the serum. In the process of transportation or inspection movement of the procoagulant blood collection tube in the prior art, the separation gel is easy to shake and adhere to the cover body or the rubber plug, and the rubber inner plug is not isolated from the outside and is easy to be stained with bacteria or dust.
