It is well known that virus sampling tube is the product of virus detection, so what is the production condition of it? Today xiaobian takes you to understand: Manufactured in 100,000-grade GMP workshop, including DEPC and other ultra-clean blood vessel system components, high-pressure steam and cobalt 60 irradiation treatment, using special process production, to ensure that the product is sterile, no RNA enzyme, no DNA enzyme, to ensure the stability of target nucleic acid molecules and no external pollution, improve the accuracy of nucleic acid detection. The above is part of the virus sampling tube production conditions and environment, to know more medical knowledge, please pay attention to Cangzhou Health medicine!

1. After blood vessels are selected for peripheral vein sampling, the needle is punctured with conventional scalp needle holding method. When blood is returned, the needle is fixed with the infusion patch, the needle handle and connector are fixed with the left finger, the vacuum tube is held in the right hand, and the end of the blood collection device is pierced into the vacuum tube. A good blood test tube should be selected before blood collection, and a tube should be changed immediately after collection. The needle Angle of blood collection should be selected according to the patient's fat and thin blood vessels. 2. It is used for the patients who have difficulty in venous blood collection of extremities such as hemorrhagic shock and systemic edema. The success rate of venous blood collection by vacuum vein needle is high. After routine skin disinfection, the operator holds the blood collecting needle in the right hand at the femoral vein location at 90° with the skin into the ne

According to the different colors of the cranium, the venous vessels are mainly divided into the following types: 1. Green tube contains heparin lithium, heparin tube is generally used for biochemical and hemorheological detection, is the best choice for electrolyte detection. Because heparin causes white blood cell aggregation, it should not be used for white blood cell counting and classification. 2. The inner wall of red head tube is evenly coated with silica to prevent wall hanging, and coagulant is added at the same time. It is generally used for hepatitis virus, thyroid function, drug testing, AIDS testing, tumor markers and other serum immunological testing. 3. Purple head tubes contain ethylenediamine tetraacetic acid (EDTA) and its salt. EDTA salt is usually used as an anticoagulant. It is used for general hematological examination such as blood count and classification, and cannot be used for blood coagulation, trace elements and PCR examination. 4. Blue - headed tube contain

Intravenous needle is mainly a disposable vacuum venous blood collection device, which is used to collect blood samples during medical examination. The venous blood collection needle consists of needle holder, connector, puncture needle, rubber part, etc., as shown in Figure 1. Vacuum blood collection device includes three parts: vacuum blood collection, blood collection needle (straight needle and scalp type blood collection needle) and needle holder. The vacuum blood vessel is the main part of it, which is mainly used for the collection and preservation of blood samples. A certain amount of negative pressure is preset in the production process of the vacuum blood collection vessel. When the blood collection needle is punctured into the blood vessel, the blood automatically flows into the blood collection tube because of the negative pressure in the blood collection tube. At the same time, a variety of additives are preset in the blood collection tube, which can fully meet the require
