Description
Technical Field
The utility model relates to a quality testing field, more specifically the wireless measuring device who is used for icterus neonatorum blue light therapeutic instrument that says so.
Background
Neonatal jaundice is a condition that bilirubin is accumulated in the body too much in the neonatal period to cause yellow symptoms of skin, mucous membrane, sclera and other parts of the whole body, and if the bilirubin is not treated in time, mental retardation, auditory disorder, death or permanent nervous system sequelae can be caused.
Neonatal jaundice is a common disease in newborns and can be generally distinguished as physiological jaundice and pathological jaundice. Physiological jaundice is that the serum bilirubin content of newborn infants is not beyond a permissible range, and the newborn infants can automatically disappear by means of feeding and excretion within a short time after birth. Beyond the physiological tolerance, we refer to pathological jaundice, which if not treated in time, can cause brain damage in the newborn, seriously affect the intelligence development, and even possibly cause death of the newborn.
At present, except for oral medicines such as anti-hepatitis-jaundice, the blue light irradiation method is mainly adopted for treating neonatal jaundice, and the method is also the most effective means at present. The blue light irradiation treatment is to uniformly irradiate the skin of the body of the newborn except eyes and genital organs by using blue light with certain intensity, and the bilirubin can absorb light, so that under the action of light and oxygen, fat-soluble bilirubin is oxidized into a water-soluble product (photo-oxidative bilirubin, namely dipyrrole) which can be discharged out of the body from bile and urine, thereby reducing the serum bilirubin concentration. The absorption band of bilirubin is 400-500 nm, especially the photolysis is strongest at 420-440 nm wavelength, the main peak of blue fluorescence wavelength is between 425-475 nm, so the blue fluorescent lamp is mostly used for treatment.
The current situation of neonatal blue light therapy in the prior art: 1. the blue light irradiation area, intensity and time can only be preset and determined manually, and cannot be adjusted in time; 2. the intensity and the uniformity of blue light irradiation are directly related to the hourly bilirubin degradation value and the bilirubin degradation rate of the blood of the infant patient, the curative effect of blue light treatment is increased along with the increase of the light intensity, and ineffective phototherapy can be avoided and the phototherapy time can be shortened by using high-intensity phototherapy; 3. the related standard of the illumination intensity of the neonatal jaundice blue-ray therapeutic apparatus corresponding to the jaundice degree does not exist at home and abroad, so most of blue-ray therapeutic apparatus instruction manuals only indicate that the intensity is adjustable, but the degree of jaundice does not exist, and the blue-ray irradiation parameter which can be referred to is provided for medical personnel according to different irradiation areas; 4. the irradiation effect is measured and evaluated in time, the jaundice index is measured by medical personnel through a percutaneous jaundice tester, and the irradiation effect of the blue-ray therapeutic apparatus is not evaluated; 5. Side effects of blue light treatment: the infant patient may have rash, diarrhea, fever, retinal damage, etc.
Therefore, the deviation, the uniformity and the fluctuation of the illumination intensity of the neonatal jaundice blue-light therapeutic apparatus are main parameters for evaluating the quality of the blue-light therapeutic apparatus. Because the current home and abroad has no calibration standard or national and industrial standards of related jaundice blue-light therapeutic apparatuses, the measurement and research of parameters such as deviation, uniformity, fluctuation and the like of the illumination intensity of the neonatal jaundice blue-light therapeutic apparatus have positive effects on the discussion and promotion of the related standard standards, the daily detection and maintenance of main quality parameters of the blue-light therapeutic apparatus are very important for knowing the performance state of the blue-light therapeutic apparatus, medical accidents derived from the blue-light therapeutic apparatus can be effectively avoided, and the clinical use risk is reduced.
