Urine analyzer, as an essential test content of clinical disease diagnosis, has an important reference value for doctors to accurately determine the cause of the focus of patients. At present, the urine detection items used in the hospital mainly include: white blood cells, red blood cells, epithelial cells, tube types, fine bacteria, fungi, crystals, sperm and other components required by clinical requirements. The basic operation is to take the sample first, and the minimum volume is 2.0ml non centrifuged urine according to the standard, and the inhalation volume is about 1.0ml. Sample processing is very convenient and fast: the sample does not need to be centrifuged, and is directly tested on the computer. It greatly saves the time of diagnosis. Therefore, the processing of urine SMT patch needs high reliability and accuracy. In the processing of urine circuit board SMT patch, Jingbang has cooperated with domestic well-known medical institutions and scientific research institutes to promote the development of domestic medical devices. At present, Jingbang is widely involved in the processing and manufacturing of many domestic medical device SMT patches.
