For blood test, many people think it is a very simple thing. In fact, blood collection, inspection, analysis of each link, there is a strict set of management norms, any link can not have the slightest careless, even if it is less eye-catching blood vessels, but also a lot of knowledge.
Not long ago, Professor Yulong Cong director of the PLA General Hospital of PLA medical laboratory quality control center in Suzhou held the BD Vacutainer vacuum vessel will be listed on the stressed that the blood quality is not good, will cause the test results are not accurate.
Venous blood sampling is the most commonly used nursing technique in clinic, and blood test is one of the necessary examination methods for clinicians to understand the patient's condition. Professor Yulong Cong said, for the test, the patient most need is "quasi" and "fast" - the result is accurate, the result is fast.
Whether the operation mode is standardized, whether the blood sample is qualified and the blood sampling equipment is up to standard may affect the accuracy of the final inspection result. In addition to infant venous blood because of difficult matter, all projects should be the principle of blood test blood.
However, there are still some hospitals where blood tests are used to collect finger blood. Finger blood is more disturbing than venous blood. It is convenient for the patient to pick the blood. It is likely to affect the accuracy of the results. If there is no special case, vein blood should be collected as much as possible.
In addition, the quality of the specimen determines the accuracy of the test results, and the factors that determine the quality of the specimen include the blood vessel collection. The factors that determine the quality of the specimen include the collection of blood vessels.
Vacuum venous blood is a technology invented in 1940s, it does not subvert the security of traditional sampling methods, fundamentally eliminate the blood pollution and the possibility of cross infection, bring a safe and convenient way for the venous blood of patients and medical staff. Nowadays, vacuum blood sampling has been widely used in clinical diagnosis and treatment.
Professor Yulong Cong pointed out that China's annual estimate to use 1 billion 800 million ~20 billion roots vacuum vessel, both at home and abroad there are a number of vacuum vessel production enterprises, but the industry is using both anticoagulant and coagulant or vacuum, vessel diameter, and pipe cover color, are not unified and strict standards, blood lead to great difference in quality.
Sealing and strong antioxidant capacity, smooth wall, no wall phenomenon, full blood sample anticoagulation, after aspiration of high vacuum degree, often can better maintain the blood sample traits, and additive proportion is not susceptible to interference.
"Manufacturers who wish to produce vacuum vessels can use the strictest international standards to provide themselves with high quality vacuum vessels."." Professor Yulong Cong stressed.
