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 reveal. The volume of the inner cavity connected with the blood taking needle is small, the influence on the blood taking volume can be ignored, but the probability of the occurrence of reverse flow is relatively small, if the volume of the inner cavity is large, a part of vacuum degree of the blood taking tube can be consumed, and therefore the collection amount of the blood taking tube is reduced.
In high altitude areas, the temperature is low, and the blood of the human body flows relatively slowly; the air pressure is low, so that the negative pressure of the conventional vacuum blood collection tube is insufficient, and the blood collection effect is influenced; at present, in actual operation, use the syringe earlier, draw the intraductal air of taking a blood sample, strengthen the negative pressure, then take a blood sample, have the following problem: the pressure in the blood collection tube cannot be accurately controlled, and the blood collection volume has errors only by the experience of an operator; when the syringe is used, gas may enter the blood collection tube due to improper operation, so that negative pressure is not generated or the tube is polluted.
In order to solve the above problems, a negative pressure blood collection tube dedicated to high altitude or low pressure areas is proposed herein.
