Background
Medical testing is a science that performs microbiological, immunological, biochemical, genetic, hematological, biophysical, cytologic, etc. tests on materials taken from the human body, thereby providing information for the prevention, diagnosis, treatment of human diseases, and assessment of human health. In the medical inspection process, blood collection is required, and the following problems occur in the blood collection process:
1. the vacuum negative pressure of the vacuum blood collection tube is relatively large, the blood flows to the tube bottom at the beginning of blood collection, the red blood cells mutually collide to cause rupture, and clinical visible hemolysis is realized.
The specific solution is as follows: when the butterfly wing blood taking needle is used for collecting blood samples, the tube plug puncture needle is obliquely inserted into the blood taking tube, so that the tube plug puncture needle is close to the side wall of the blood taking tube, blood slowly flows down along the tube wall, and the rupture caused by direct impact of red blood cells is avoided.
2. The vacuum tube is used for absolutely preventing blood from flowing back in the blood sampling process so as to avoid countercurrent infection, the vacuum blood sampling tube pressure is equal to the blood vessel internal pressure when blood sampling in the vacuum blood sampling tube is finished, and the blood sampling tube is rapidly lowered to return to normal pressure due to the fact that the blood sampling tube internal pressure is rapidly lowered, and at the moment, the vacuum blood sampling tube pressure which keeps the blood sampling tube state is larger than the blood vessel internal pressure, so that blood is likely to return to the blood vessel again. The specific preventive solution is: in the process of taking blood by the vacuum tube, blood in the blood taking tube cannot be connected with the puncture needle, the blood taking tube is pulled out firstly after the blood taking is finished, then the tourniquet is loosened, and finally the venous blood taking needle is pulled out.
3. After the blood collection of the vacuum blood collection tube is completed, the coagulation phenomenon can occur after long-term standing.
The specific solution is as follows: after the blood collection of the vacuum blood collection tube is completed, the vacuum blood collection tube is repeatedly rocked for 180 degrees, so that the anticoagulant in the vacuum blood collection tube is fully fused with the blood.
Generally, the above operations are performed manually by a professional medical staff, and in order to increase reliability and convenience, a blood collection device for medical examination needs to be designed according to the cause and solution of hemolysis.
