The price of a closed needle is about 30~200 yuan, there is no uniform standard, which depends on what kind of disease the patient suffers from, the level of the hospital, the choice of drugs and so on. If the patient is only localized simple aseptic inflammation, and injection of relatively cheap hormone drugs and lidocaine, etc., generally about 30 ~ 50 yuan. If the injection of relatively good hormone drugs, the cost may be relatively high, will reach about 100 yuan, in addition to the cost of the doctor’s own technical costs also include the specific cost of drugs. If the patient has a local joint cavity injection, such as the knee joint injection of sodium vitrate and other drugs, its cost is generally relatively high, can reach 100 ~ 200 yuan. In addition, the cost of closed needle injection is also affected by the level of the hospital, tertiary hospital injection costs are generally relatively high, the cost of first-class and second-class hospitals is relatively low, in short, the specific cost of the closed needle is not a unified standard of judgment, affected by a variety of factors.
