Clinical Application of Vacuum Blood Collection Method in Journal of Hangzhou Medical College Zhou Qian Zhang Chunmei 21. The First Affiliated Hospital of Zhejiang University School of Medicine. Zhejiang Hangzhou 31;2 The Shaw Run Hospital, School of Medicine, Zhejiang University. Zhejiang Hangzhou 310016 Venous blood sampling is a clinical treatment. For the more frequent technical operations, the needle sampling method used in the past was time consuming, laborious, and easily contaminated, and the blood cells were easily damaged. If the amount of blood collected was inaccurate, Will affect the test results. Since the vacuum blood collection method was adopted, the time was greatly saved, the contamination of blood samples was avoided, and the accuracy of the amount of agricultural products was ensured. 1 Tool and method 1.1 The tool used was a vacuum blood collection kit produced by U.S. Corporation, including a vacuum blood collection jacket, and vacuum blood collection. Needle and blood test with negative pressure, as well as conventional venous blood plate.

1.2 Methods Carry the substance to the patient's bedside, do a good job of checking, explain to the patient the method and purpose of vacuum blood collection, take out the vacuum for blood collection, and install a vacuum needle to use. Select veins as usual. Remove your skin from the skin with a vacuum needle at a 15 degree angle and then pierce the blood vessel. However, from the outside, the tail was pushed to collect blood test tubes. The blood will automatically flow into the tube and the blood will automatically stop flowing when the standard volume is reached. At this point, the tube can be pulled out. Then pull out the needle according to the conventional method and press the puncture site. If no blood flows out after the test tube is installed, the tube can be punctured from different angles again until the blood flows out automatically. If you need a variety of different blood samples can be pulled out of the blood test tube, re-install the desired test tube, for blood collection. When a variety of blood specimens need to be taken at the same time, an ordinary dry test tube should be used to pick up the anticoagulant tube.

2 Advantages and Disadvantages of Ordinary Venous Blood Collection and Vacuum Venous Blood Collection 2.1 The disadvantage of using a common syringe to draw blood specimens is that the speed of blood pumping is slow, and multiple aspirations can also cause damage to blood cells.

If the blood draw is not enough to try to get blood again, the needle must be pulled out for the first injection, which increases the patient's pain. During the process of injecting the blood in the syringe into the test tube, it is easy to be contaminated and easy to injure the operator. 2.2 Intravenous Vacuum Blood Collection The negative pressure of the test tube is preset according to the blood sampling scene, so that when the blood is collected, the blood is automatically drawn into the test tube. When the negative pressure disappears, the outflow of blood also stops automatically and the dose is accurate. The speed of blood suction is relatively uniform, and it is not easy to cause destruction of blood cells, and blood can be taken into the tube several times without repeatedly puncturing the insufficient blood volume in the syringe. In the course of blood sampling, the valve is sealed in In the cavity. The danger of not being blood-stained again protected the operator. However, it also has the definite drawback that it cannot be left in the vein and is not suitable for rescue patients.

2.3 After many years of clinical use, most patients currently undergo vacuum blood collection methods. This method will reduce the anxiety of loyalty to a certain extent and shorten the time for blood collection. At the same time, the use of Funing blood collection can well avoid blood contamination of operators and reduce the chance of cross-infection.
