Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a combined blue light box cover for newborns. Background Technology

[0002] Neonatal jaundice is a common clinical problem in newborns. Due to the unique characteristics of bilirubin metabolism in newborns, approximately 50%-60% of full-term infants and 80% of premature infants develop physiological jaundice, while some of these infants may develop pathological jaundice. If high bilirubin levels are not treated promptly, they can lead to serious complications such as bilirubin encephalopathy, affecting the development of the newborn's nervous system and potentially causing permanent neurological sequelae such as hearing impairment and intellectual disability. Given the limitations of drug therapy and exchange transfusion, phototherapy has emerged. As a non-invasive, relatively safe, and effective treatment for neonatal jaundice, phototherapy has been widely used clinically. It primarily works by irradiating the newborn's skin with blue light of a specific wavelength, causing a photochemical reaction in the superficial tissues of the skin, converting bilirubin from lipid-soluble unconjugated bilirubin into a water-soluble isomer, which is then easily excreted through bile and urine, thus lowering bilirubin levels. However, some phototherapy devices, due to the blue light being positioned at the top, may experience blue light leakage. Blue light leakage can not only cause potential light damage to the eyes of surrounding medical staff, and long-term exposure may lead to eye problems such as retinal disease, but it may also affect the normal rest and health of other newborns in the same ward.

[0003] Existing light-shielding covers, such as the one disclosed in CN 215307717 U for a neonatal phototherapy box, include a top curtain and side curtains connected to the four sides of the top curtain. The side curtains include a front curtain, a rear curtain, a left curtain, and a right curtain. Each side curtain is independent and not connected to the others, but adjacent side curtains are fixed together with Velcro. The left and right curtains have symmetrically arranged square ventilation holes, and the rear curtain has a circular ventilation hole. The positions of the circular and square ventilation holes correspond to the positions of the ventilation openings on the neonatal phototherapy box. The front and rear curtains have symmetrically arranged operating windows with hinged covers, the area of ​​which is larger than the area of ​​the operating window. The left or right side of the hinged cover is sewn to the corresponding curtain, and the other three sides are fixed to the curtain with Velcro. The structure features separate operating and viewing windows; however, certain problems still exist in its use. For example, the position of the viewing window requires accompanying medical staff or family members to stand at a certain angle to observe the newborn's condition. The size and model of the enclosure are not suitable for most blue light boxes, and the limitations of the operating window require frequent opening of the curtain, causing some inconvenience in actual operation. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of inconvenient observation, poor fit, and operational difficulties of existing blue light box covers.

[0005] To achieve the above objectives, the technical approach adopted by this utility model to solve its technical problem is as follows: Given that most blue light sources are located at the top of the blue light box, a blue light box cover with a sliding viewing window is designed. This viewing window is located around the bottom of the blue light box cover and is at a certain height, allowing medical staff to observe the newborn's condition at any time. Simultaneously, a clamping device is equipped at the top of the blue light box, and the light-blocking cloths on the top and sides of the blue light box cover are independently connected to this clamping device. In this way, the height of the light-blocking cloths can be flexibly adjusted according to actual needs, thereby adjusting the height of the viewing window. For example, when changing a newborn's diaper, the light-blocking cloths can be pulled upwards to bring the viewing window to eye level, at which point the operating window is exposed, protecting the eyes of medical staff without obstructing the operating area.

[0006] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] Design a modular blue light therapy box cover for newborns. The specific design is as follows:

[0008] A modular blue light box cover for newborns includes a light-blocking cloth, characterized in that multiple light-blocking cloths are disposed on the side of the blue light box; a clamping frame is disposed on the top of the blue light box, and the clamping frame is engaged with the light-blocking cloth.

[0009] Furthermore, a viewing window is provided at the bottom of the blackout cloth.

[0010] Furthermore, the clamping frame includes a telescopic part and sliding frames disposed at both ends of the telescopic part, the telescopic part sliding up and down within the sliding frames.

[0011] Furthermore, the telescopic part includes a fixed telescopic part that is fixedly connected to the sliding frame and a movable telescopic part that is slidably connected to the sliding frame.

[0012] Furthermore, both ends of the movable telescopic part are equipped with limiting devices and sliding blocks that cooperate with the sliding frame to limit the movable telescopic part.

[0013] Furthermore, a light-blocking cloth is provided between the fixed telescopic part and the movable telescopic part to clamp the light-blocking cloth.

[0014] The beneficial effects of this utility model are:

[0015] 1. With its adjustable light-blocking cloth design, the light-blocking cloth can be adjusted upwards to position the viewing window appropriately during operations such as diaper changing, just enough to expose the operating opening. This allows medical staff to clearly observe the newborn's condition for accurate operation while ensuring ease of operation, effectively solving the problems of inconvenient observation and operational difficulties associated with existing light-blocking cloths.

[0016] 2. The light-blocking cloth consists of multiple pieces that snap into the clamping frame on top of the Blu-ray box. This modular design allows the box cover to better fit Blu-ray boxes of different sizes, overcoming the drawback that the size and model of existing light-blocking covers are not suitable for most Blu-ray boxes, thus improving the product's versatility and practicality.

[0028] refer to Figure 1-7 A modular blue light box cover for newborns includes a light-blocking cloth 10 and a top clamping frame 20 disposed on the blue light box 30.

[0029] In practice, the light-blocking cloth 10 uses a multi-layered composite light-blocking fabric. Its outer layer is made of wear-resistant, stain-resistant, and easy-to-clean polyester fiber, capable of resisting friction and stains during daily use. The inner layer is a metal oxide-coated fabric with high reflectivity. This coating effectively reflects blue light and is chemically stable, non-toxic, and harmless, making it suitable for use in medical equipment environments where newborns come into contact with it. Discontinuous Velcro fasteners are provided on both sides of the light-blocking cloth 10, allowing two adjacent pieces to be glued together to prevent light leakage. A viewing window 11 is located near the bottom of the light-blocking cloth 10, with a height adjustable to 10-15 cm and a distance of 10 cm from the bottom to provide sufficient visibility for observing the newborn. The width is the same as that of the blackout cloth 10. The material is a blue light blocking plastic film, which blocks blue light while ensuring a certain degree of transparency to ensure visibility. A blackout curtain 12 can be sewn above the viewing window 11. When observation is needed, the blackout curtain 12 can be lifted to observe through the viewing window 11. When observation is not needed, the blackout curtain 12 can be lowered to block light. The back of the blackout curtain 12 is provided with a first Velcro 121 that can be attached to the top of the viewing window 11, so that the blackout curtain 12 can be opened for a long time for convenient observation.

[0030] In a specific implementation, the clamping frame 20 includes a telescopic part 21 and sliding parts 22 disposed at both ends of the telescopic part 21. The telescopic part 21 includes a fixed telescopic part 211 and a movable telescopic part 212.

[0031] The telescopic part 21 has a fully extended length of 85-90 cm and a fully retracted length of 30-40 cm.

[0032] The sliding part 22 consists of four hollow rectangular connectors 221. Each of the two adjacent sides of the connector 221 is provided with a sliding groove 222. A fixed telescopic part 211 is provided below the sliding groove 222. The two are integrally formed. A limit hole 223 is provided on the other side adjacent to the sliding groove 222. A limit groove 224 is provided on the side of the connector 221 opposite to the limit hole 223.

[0033] The fixed telescopic part 211 includes a telescopic sleeve 2111 and a telescopic tube 2112. One end of the telescopic sleeve 2111 is fixedly connected to the connector 221 and is located below the sliding groove 222. The other end is connected to the telescopic tube 2112, which is located inside the telescopic sleeve 2111 and slidably connected thereto. The diameter of the telescopic tube 2112 is smaller than that of the telescopic sleeve 2111. One end of the telescopic tube 2112 is provided with a limit ring 225, which cooperates with one end of the telescopic sleeve 2111 and is provided with a rubber ring. When the telescopic tube 2112 is inside the telescopic sleeve 2111... When sliding, it can provide good friction, so that the two will not slide relative to each other without external force; the other end of the telescopic tube 2112 is fixedly connected to another connector 221 and is set below its sliding groove 222; when the two connectors 221 approach each other, the telescopic tube 2112 gradually slides into the telescopic sleeve 2111; when the two connectors 221 separate, the telescopic tube 2112 gradually extends out of the telescopic sleeve 2111, and due to the action of the limiting ring 225, the telescopic tube 2112 cannot fully extend out of the telescopic sleeve 2111.

[0034] The telescopic structure of the movable telescopic part 212 is similar to that of the fixed telescopic part 211. Both ends of the movable telescopic part 212 are provided in the limiting groove 224, and both ends are symmetrically provided with limiting devices 213 and sliding blocks 214. The limiting device 213 includes a spring hole 2131 opened on one side of the movable telescopic part 212 and a spring 2132 provided in the spring hole 2131 with one end fixedly connected thereto. The other end of the spring 2132 is fixedly connected to a limiting post 2133. The other end of the limiting post 2133 has an arc and cooperates with the limiting hole 223. The sliding block 214 cooperates with the limiting groove 224. When the movable telescopic part 212 slides up and down inside the sliding groove 222, the sliding block 214 slides inside the limiting groove 224, the spring 2132 is in a compressed state, and the limiting post 2133 abuts against the inner wall of the connecting member 221. When the limiting post 2133 cooperates with the limiting hole 223, the spring 2132 is in an extended state, and the limiting post 2133 can limit the movable telescopic part 212, and the device is in a locked state. When the limiting post 2133 is pressed, the spring 2132 continues to be in a compressed state, the limiting post 2133 abuts against the inner wall of the connecting member 221, and the movable telescopic part 212 can continue to slide up and down, and the device is in an active state.

[0035] The fixed telescopic part 211 and the movable telescopic part 212 are a group, and there are four groups in total in this device. They cooperate with the connector 221 to form a rectangle.

[0036] In specific implementation, the upper end of the light-blocking cloth 10 is located between the movable telescopic part 212 and the fixed telescopic part 211. When the device is in the active state, the light-blocking cloth 10 can be adjusted up and down. When the device is in the locked state, the movable telescopic part 212 and the fixed telescopic part 211 clamp the light-blocking cloth 10 to fix it.

[0037] In specific operation, adjust the length and width of the active clamping frame 20 to a suitable size and place it on top of the Blu-ray box 30. If the heat dissipation device of the Blu-ray box 30 is on top, then do not place the light-blocking cloth 10 on top. If there is no heat dissipation device on top, then place the light-blocking cloth 10 on top, and the light-blocking cloth 10 on top does not have a viewing window 11. Then adjust the height of the light-blocking cloth 10 around the perimeter and place it between the fixed telescopic part 211 and the movable telescopic part 212, and adjust it to the locked state. Pinch the second Velcro 40 on both sides of the light-blocking cloth 10 to prevent light leakage.

[0038] When changing a newborn's diaper or performing other related procedures, first loosen the second Velcro 40 on the side light-blocking cloth 10, then adjust the light-blocking cloth 10 upwards. During adjustment, the viewing window 11 should be positioned at approximately one-third of the height of the phototherapy box 30. This ensures that the operating port on the phototherapy box 30 is fully exposed, facilitating the necessary procedures for medical staff. Furthermore, this process allows medical staff to clearly observe the newborn's condition inside the phototherapy box through the viewing window 11 to smoothly complete the procedure, while effectively preventing blue light leakage that could harm their own eyes, thus ensuring the safety of medical personnel.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
