Skills of dealing with insufficient vacuum of disposable vacuum collection vessel

       Disposable vacuum blood collection has been widely used in clinic, easy to operate, fast to use, welcomed by nurses. However, sometimes the vacuum of the vacuum blood collection vessel is insufficient, which will not only cause no bleeding, but also make the blood flow back to the vessel. When the blood collection needle is removed, the blood will pollute the bedding, and even pollute the hands of the operator, resulting in the contact infection of the operator. This method has been repeated clinical practice in our department, and it is feasible

      When a small amount of blood flows into the blood collection vessel (indicating insufficient vacuum) and the blood begins to flow back, the rubber cap of the vacuum blood collection vessel is routinely disinfected. The syringe is inserted into the blood collection vessel through the rubber cap of the blood collection vessel and a small amount of air is pumped out to increase the negative pressure of the blood collection vessel and the blood flows into the blood collection vessel, Then remove the blood sampling needle to prevent blood overflow, and then pull out the syringe.

        Advantages: it can reduce the pain of patients caused by multiple puncture, avoid the pollution caused by blood overflow, and avoid the embarrassment of nurses during operation. This method is easy to operate, time-saving, improve the work efficiency of nurses, at the same time, it is convenient to draw materials, economic and health.

      Guangxi disposable vacuum blood collection tube is composed of tube, rubber stopper, tube cap, additive (if any) and label. It is mainly used in hospitals, medical research institutions, blood stations, health and epidemic prevention stations and other units for blood sample collection.The vacuum blood collection tube is made of medical glass or PET material, and the collected blood will not have any reaction with the vacuum blood collection tube. Totally enclosed vacuum blood vessels do not make blood contact with operators directly, thereby avoiding harmful conditions such as unclean spray, cross infection, and so on. The specification and color of test tube cap can be changed according to the contract.

       Disposable vacuum blood collection is used in biochemical, immune, serum and other clinical medical tests to obtain high-quality serum samples. Serum separation gel is a kind of semi-solid inert gel composed of several compounds. The separation gel is composed of medical polymer materials. After blood collection and centrifugation, it will be separated into serum (upper layer), serum separation gel (middle layer) and blood cells (lower layer). A thick layer of serum separation gel in the middle of the test tube can completely isolate the serum and blood cells, so that the blood cells can not contact the serum, thus ensuring the purity of the serum. During the operation, after the blood is collected to the separation gel test tube, the separation gel tube is put into the centrifuge immediately and gently reversed for 3-5 times (to fully mix the blood with the accelerator). After the blood is completely coagulated (generally about 18 minutes), the separation gel tube is placed in the centrifuge, the centrifugal speed is guaranteed at 3500rpm / min, and the ideal serum can be obtained after centrifugation for 10-15 minutes. The tube can be directly placed into the automatic biochemical instrument for biochemical detection.
