Description

Technical Field

[0001] The utility model relates to the technical field of jaundice instruments, and in particular to a calibration device for a transcutaneous jaundice instrument. Background Art

[0002] Neonatal jaundice, also known as neonatal hyperbilirubinemia, is one of the common diseases in newborns, especially premature infants. It is caused by abnormal bilirubin metabolism in the body, which leads to excessive accumulation of bilirubin in the body. Clinically, the skin, sclera, mucous membranes and other tissues are stained yellow. Bilirubin concentration is the main basis for determining neonatal jaundice.

[0003] Neonatal jaundice is divided into physiological jaundice and pathological jaundice according to its mechanism and severity. Among them, pathological jaundice is one of the difficulties in neonatal disciplines. It is caused by multiple causes and pathogens, and is difficult to diagnose and treat. Pathological jaundice refers to a bilirubin concentration greater than 35 μmol / L 1 hour after birth, or a daily increase in serum bilirubin exceeding 855 μmol / L or a single measurement concentration value greater than 205 μmol / L, deep yellowing, large area, and accompanied by symptoms such as edema, anorexia, and dyspnea. Pathological jaundice may be complicated by kernicterus or brain tissue damage, which threatens the health and life of the newborn in severe cases. A large number of clinical trials have shown that if the bilirubin concentration of patients with neonatal jaundice can be detected and prevented in a timely and effective manner at an early stage, it is very beneficial for the early detection, screening, and timely treatment of pathological jaundice; it can also alleviate the condition and shorten the course of treatment. Therefore, timely detection of whether a newborn has jaundice and the degree of jaundice is crucial to the entire treatment process.

[0004] At present, there are two main types of clinical methods for detecting bilirubin concentration: invasive detection method and non-invasive detection method. The former refers to the serum detection method, which usually uses the bilirubin concentration measured by venous blood test or trace blood as the main indicator, and uses a biochemical analyzer for detection. This method is relatively mature and has high accuracy, and is the gold standard for bilirubin detection. However, this method is based on the analysis of blood samples of newborns, and requires frequent blood draws from newborns, which not only causes pain to the children, but also increases the risk of clinical infection. Therefore, the invasive detection method based on blood sample analysis is not suitable for continuous monitoring of bilirubin in newborns. The non-invasive detection method mainly uses the optical properties of bilirubin or the skin color characteristics of jaundice patients to detect bilirubin levels, and is carried out by irradiation or imaging, so there is no disadvantage of blood sampling. This method is easy to operate, rapid in detection, and harmless to newborns. Its measurement results have become an important basis for the clinical diagnosis and monitoring of neonatal jaundice.

[0005] As a typical representative instrument of non-invasive detection method, transcutaneous jaundice meter is non-invasive, convenient and simple. It can realize continuous monitoring of neonatal bilirubin level, so it is widely used in NICU / PICU and neonatal department of major hospitals. The accuracy of its measurement value has also attracted the attention of medical staff and patients' families. It is necessary to verify or calibrate the neonatal jaundice meter in clinical use to ensure the accuracy and reliability of the measurement data. Utility Model Content
