China Quality News Online Recently, according to the provisions of the law of the people's Republic of China on the quantity of domestic products and the regulations of Zhejiang Province on the supervision of product quality, Zhejiang Provincial Bureau of quality and technical supervision organized the supervision and spot check of blood pressure meters (sphygmomanometers) products, and spot checked 6 batches of sphygmomanometers (sphygmomanometers) products from 6 enterprises in Wenzhou area, with 0 batch of unqualified products and 0 batch unqualified rate Limited company Wenzhou Jianda Medical Instrument Co., Ltd. Wenzhou Dongfang Medical Instrument Co., Ltd. Wenzhou Fengrui Medical Instrument Co., Ltd. Wenzhou Kangju Medical Instrument Co., Ltd
Sphygmomanometer (sphygmomanometer) has the characteristics of simple structure, small size, clear indication and convenient use. It is not only a medical device for measuring human blood pressure, but also a pressure measuring instrument. Sphygmomanometers (sphygmomanometers) belong to the products under the management of the manufacturing license of measuring instruments in China. When users select sphygmomanometers (sphygmomanometers), they should first recognize the CMC manufacturing license mark of the products.
Precautions for use of sphygmomanometer: 1) before measuring blood pressure, it is necessary to check whether the pointer of sphygmomanometer is within the zero mark line. If the pointer points beyond the zero mark line, it needs to be sent to relevant departments for maintenance and verification. 2) When using sphygmomanometer to measure blood pressure, pay attention to whether the pointer deflection is stable, and the pointer shall not be bouncing, stuck or sluggish in the process of rotation, otherwise it shall also be sent to relevant departments for maintenance and verification in time. 3) Because of the internal structure of sphygmomanometer and the elastic element of capsule, the long-term use of sphygmomanometer is easy to cause excessive deviation of indication value, so its stability is not as good as that of mercury sphygmomanometer, so it needs to be calibrated frequently.
Precautions for use of sphygmomanometer: 1) before use, open the upper cover of sphygmomanometer. After the upper cover is fully opened, the mercury glass tube should be in a vertical position. 2) Before measuring blood pressure, it is necessary to check whether the mercury convex surface in the glass tube is tangent to the zero scale line. If the mercury convex surface is higher than 0.5kpa or lower than 0.2kpa above the zero scale line, it shall be sent to the relevant department for maintenance and verification. 3) In the process of blood pressure measurement, if the mercury in the glass tube is broken or bubbles are blown over, the measurement shall be stopped immediately. The blood pressure measured by the sphygmomanometer will have a large error, which shall be sent to the relevant departments for maintenance and verification. 4) After the completion of blood pressure measurement, the sphygmomanometer shall be tilted 45 ° to the right, so that all Mercury will enter the mercury storage bottle, and the switch shall be closed to avoid mercury leakage.
Sphygmomanometer (sphygmomanometer) is a kind of compulsory measuring instrument. The accuracy of the indication of sphygmomanometer (sphygmomanometer) is directly related to the accuracy of blood pressure measurement and human health. Therefore, in the use of sphygmomanometer (sphygmomanometer), it is particularly important to carry out the first and periodic verification of sphygmomanometer (sphygmomanometer) correctly.
