Abstract
Description
Technical Field
[0001] The utility model relates to the field of calibration of measuring instruments, in particular to a calibration bracket used for calibrating a transcutaneous jaundice detector. Background Art
[0002] Neonatal jaundice has a high incidence rate. Severe pathological jaundice may cause hearing loss, cerebral palsy, mental retardation, etc. in children. Therefore, timely and effective detection of bilirubin concentration in jaundiced newborns is the key to early detection, screening, timely treatment of pathological jaundice, and prevention and treatment of high bilirubin damage to tissues and organs. For children with pathological jaundice, bilirubin positive can be determined when the bilirubin concentration exceeds 12 mg / dl. Severe cases require phototherapy treatment. During treatment, the jaundice index and degree of the child need to be confirmed multiple times. The transcutaneous jaundice detector (hereinafter referred to as the jaundice meter) is an instrument that can non-invasively monitor bilirubin concentration by measuring the forehead, anterior chest wall, left and right cheeks and other parts of the newborn. Because its measurement process is simple to operate and non-invasive, it is widely used in medical institutions.
[0003] The jaundice meter uses the reflectance spectroscopy method in the optical detection method based on Lambert-Beer's law to determine the bilirubin concentration in the skin tissue of newborns. The probe of the jaundice meter contains a xenon flash light source and a sensor for receiving light intensity. When measuring, the probe needs to be placed on the baby's forehead, and the flash light is activated by pressing the probe vertically. The light emitted by the xenon flash light is guided to the skin surface through the optical fiber of the outer ring of the probe and directly irradiated under the skin. The light wave is repeatedly scattered and absorbed in the skin tissue, and finally returns to the optical fiber of the inner ring of the probe and is transmitted to the corresponding photodiode. The jaundice meter calculates the difference in optical density of the blue light and green light waves to obtain the measured value of transcutaneous bilirubin concentration. Because the emission and reception of the jaundice meter light are in the same plane, the probe and the skin need to be kept vertical and in full contact during measurement. If it is tilted, it will cause deviations in the emission and reception of light intensity, resulting in inaccurate measurement results. Utility Model Content
