Description

Technical Field

[0001] The utility model relates to the field of protective eye masks, in particular to an adjustable neonatal phototherapy protective eye mask. Background Art

[0002] Phototherapy is a treatment for neonatal jaundice by irradiating the skin with light, which converts the bilirubin in the body into water-soluble bilirubin isomers under the oxidative action of light. It does not need to be combined with glucuronic acid and can be excreted from bile and urine, thereby reducing the bilirubin in the serum and preventing unconjugated bilirubin from passing through the blood-cerebrospinal fluid barrier and entering the skull to cause bilirubin encephalopathy.

[0003] In the prior art, in order to prevent blue light from damaging the eyes of newborns during phototherapy, the eyes of newborns are often covered with protective eye masks during phototherapy. The "newborn phototherapy protective eye mask" disclosed in Chinese Patent No. (CN217793575U) includes an outer frame, an adhesive sheet, a shielding layer, a film layer and a fixing belt. The inner part of the outer frame is fixed with an adhesive sheet, the front surface of the adhesive sheet is fixed with a shielding layer, the front surface and the back surface of the adhesive sheet are both adhesively fixed with a film layer, and the left and right ends of the front surface of the outer frame are fixedly connected with fixing belts;

[0004] Although the utility model can effectively block visible light during use, effectively protect the eyes of infants from visible light stimulation during neonatal phototherapy, and is comfortable, safe and not easy to fall off when worn by newborns;

[0005] However, since the head circumference of each newborn is different, the protective eye mask has poor adaptability when worn on the head of a newborn only by means of a fixed length fixing strap and Velcro. If the newborn's head circumference is large, it will be tight when worn on the newborn's head, which may cause discomfort to the newborn. If the newborn's head circumference is small, it will be easy to fall off when worn on the newborn's head. As a result, the protective eye mask cannot be adjusted according to the newborn's head circumference so that it can be comfortably worn on the newborn's head, which brings inconvenience to the adjustment and use of the protective eye mask. Utility Model Content

[0006] The main purpose of the utility model is to provide an adjustable neonatal phototherapy protective eye mask, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] Disclosed is an adjustable neonatal phototherapy protective eye mask, comprising a protective eye mask body and a strap, wherein the left and right sides of the protective eye mask body are respectively provided with limiting mechanisms, and the limiting mechanisms comprise side plates, a fixing rod, a compression spring, a movable plate, a pull ring and a connecting rod, wherein the side plates are fixedly connected to the left and right sides of the protective eye mask body, and the upper and lower ends of the side plates are respectively fixedly connected with fixing rods, and the outer sleeve of the fixing rod is provided with a compression spring, and the movable plate is movably connected to the front end wall of the side plate through sliders at the upper and lower ends, and the slider is movably connected to the fixing rod through a connecting hole on the side wall and fixedly connected to the inner end of the compression spring, the limiting rod is fixedly connected to the inner side wall of the movable plate, the connecting rod is fixedly connected to the outer left side of the pull ring, and the connecting rod is movably connected to the movable plate through a rotating block on the inner end.

[0009] Preferably, the strap is U-shaped, and a plurality of groups of vertically symmetrical adjustment holes are provided on the left and right side walls of the strap.

[0010] Preferably, side panels are fixedly mounted on the left and right side walls of the protective eye mask body, and a through opening is provided on the front end wall of the side panel, sliding openings are provided on the inner top and bottom surfaces of the through opening, and a through hole connected to the through opening is provided on the outer side wall of the side panel, and a vertical opening staggered with the through hole is provided on the outer side wall of the side panel.

[0011] Preferably, the fixing rod is fixedly installed in the sliding mouth, and a compression spring is sleeved on the outside of the rod body of the fixing rod, a sliding block is fixedly installed on the inner side wall of the compression spring, and a connecting hole is opened on the side wall of the sliding block and is movably installed with the fixing rod through the connecting hole.

[0012] Preferably, the movable plate is fixedly installed between upper and lower symmetrical sliders, and a limit rod corresponding to the adjustment hole is fixedly installed on the inner side wall of the movable plate, and a convex groove is opened on the outer side wall of the movable plate.

[0013] Preferably, a connecting rod is fixedly mounted on the left side wall of the pull ring and passes through the through hole, a rotating block is fixedly mounted on the inner end of the connecting rod and is movably mounted in the convex groove, and a transverse rod is also fixedly mounted on the outer wall of the connecting rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a binding strap and a limiting mechanism for use with the protective eye mask body. According to the size of the newborn's head circumference, the two ends of the binding strap are passed through the through opening and pulled in opposite directions on both sides, so that the protective eye mask body is tightly attached to the eyes of the newborn under the action of the binding strap. After the pull ring is rotated to align the rotating block on the connecting rod with the vertical opening, the movable plate is pushed inwardly by the slider under the elastic extension action of the compression spring, so that the limiting rods on the inner side of the movable plate are inserted into the adjustment holes corresponding to the current positions opened on both sides of the binding strap. In this way, the protective eye mask body can be worn on the head of the newborn and the eyes can be shielded and protected. Therefore, the protective eye mask body can be effectively adjusted to be worn on the head of the newborn according to the size of the newborn's head circumference, and the problem of the protective eye mask body being too tight or too loose after being worn can be avoided, thereby achieving the purpose of facilitating the adjustment and wearing of the protective eye mask body.
