Neonatal shading dressing and preparation method thereof

Abstract

The invention relates to a neonatal shading dressing for eye protection of neonatal phototherapy, which consists of a light shielding layer, a supporting layer, a hydrogel layer and a separating layer, a preparation process comprises the following steps: 1) weighing 4 to 10% polyacrylic resin, 0.03 to 0.3% of dihydroxyaluminum aminoacetate, 0 to 0.3% of EDTA, and 15 to 30% of glycerin according tothe formula, and uniformly mixing the materials to obtain a glycerin phase; 2) dividing deionized water into three equal parts, weighing 0.1-1% of tartaric acid according to the formula, dissolving the material in 1 part of deionized water, and spreading 1-3% of carbomer on the liquid surface for overnight use to obtain a water phase 1; uniformly dispersing 0-2% of sodium carboxymethyl cellulosein another portion of deionized water, and swelling the material overnight to obtain a water phase 2; taking 1 part of water, adding 0.4-10% of polyvinylpyrrolidone to the water to dissolve completelyto obtain a water phase 3; and uniformly mixing the water phase 1 and the water phase 2 to obtain a water phase 4; and 3) adding the glycerin phase to the water phase 4, and after vacuum stirring for2 to 4 minutes, adding the water phase 3, uniformly mixed hydrogel, and obtaining the product after coating, cutting, packaging and the like.

Description

technical field [0001] The invention relates to a newborn light-shielding dressing, in particular to a light-shielding dressing capable of protecting eyes from blue light damage during phototherapy for neonatal jaundice. Background technique [0002] Newborns, especially premature infants, often have elevated bilirubin and hyperbilirubinemia in the first few days after birth, requiring blue light irradiation therapy. In the process of blue light irradiation treatment, in order to avoid the damage of blue light to the eyes of children, it is necessary to take protective measures for the eyes of children. Patent No. 201120028280.9 in China discloses a novel blue-ray eye mask. Its technical solution is: comprising an eye mask, an elastic elastic band and a Velcro, the two ends of the eye mask are provided with an elastic elastic band, and the elastic elastic band is connected by a Velcro. The defects of this blue light eye mask are: 1. It is difficult to control the tightness ...

AI Technical Summary

Problems solved by technology

The defects of this blue light eye mask are: 1. It is difficult to control the tightness of the elastic elastic band during use. If it is too tight, it will easily oppress the eyes, and if it is too loose, it will easily fall off; and side-to-side displacement, causing the eyes to be exposed to blue light

The defect of this neonatal eye mask is: 1, when the elastic cover body fixes the light-shielding belt, it is difficult to select the size of the cover body, if it is too large, the light-shielding belt is not firmly fixed on the eyes of the infant, and it is easy to move and fall off; The head and eyes of the child are under too much pressure, oppressing the eyeball, and affecting the local blood supply and comfort around the eyes. The child does not cooperate with phototherapy; the size of each newborn's head circumference varies

2. After the cover covers the entire head, it can effectively avoid the up and down displacement of the shading belt; however, when the cover is in contact with the phototherapy bed or pillow during use, when the child's head turns, it will usually cause a gap between the cover and the head. Rotation occurs, causing the visor to move from side to side, exposing the child's eyes to blue light

[0003] The current fixing methods of blue light protective goggles for newborns are basically the above two fixing methods: bundled and headgear. No matter how these two methods are improved, due to their design defects, it is difficult to avoid the difficulty of tightness control and the Side-to-side, up-and-down movements leading to eye exposure defects
