Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a light therapy cover cloth for a blue light box. Background Art

[0002] Neonatal hyperbilirubinemia is a common clinical condition in newborns, causing yellowing of the skin, sclera, and other organs due to elevated serum bilirubin (mostly unconjugated bilirubin). It accounts for approximately 30% to 50% of hospitalized neonatal ailments. This condition can be categorized as physiological or pathological jaundice. The diagnostic criteria in the fourth edition of Practical Neonatology are total serum bilirubin >220.6 μmol / L (12.9 mg / dL) in full-term infants and >255 μmol / L (15 mg / dL) in premature infants. If left untreated or treated inappropriately, some children with unconjugated hyperbilirubinemia may develop bilirubin encephalopathy (kernicterus), a condition with a mortality rate exceeding 10% and a long-term sequelae rate of approximately 70%, primarily resulting in permanent damage to the nervous system, such as cerebral palsy, vision impairment, and hearing loss. Currently, there are many methods to treat hyperbilirubinemia, including drugs, phototherapy, blood transfusion, etc. Among them, blue light therapy is the main treatment strategy with relatively good clinical efficacy.

[0003] Blue light irradiation is a simple, effective, and fast-acting method for treating neonatal hyperbilirubinemia and is widely used to treat neonatal hyperbilirubinemia. Blue light therapy is widely used clinically because blue light irradiation can oxidize and decompose indirect bilirubin in the blood into water-soluble bilirubin, which is then excreted from the body in bile and urine, thereby achieving the purpose of treating neonatal hyperbilirubinemia.

[0004] Bilirubin can absorb light, and the strongest effect is on light with a wavelength of 450-460nm, while the main peak of blue light wavelength is at 425-475nm. At present, the most commonly used phototherapy instrument in domestic clinical practice is the double-sided blue light box produced in my country, which has two lamps on the upper and lower sides. The light life is about 5000 hours, and its phototherapy wavelength range is 335-600nm (the main peak is 425-475nm). Conventional blue light therapy generally has a phototherapy intensity of <20W / (cm 2 ·nm), while enhanced phototherapy requires the phototherapy intensity to reach>30μW /

[0005] (cm 2 Foreign studies have shown that 24-48h enhanced phototherapy can more effectively reduce serum bilirubin levels than conventional phototherapy [0.26mg / (dl·h) vs 0.14mg / (dl·h)]. Furthermore, in addition to increasing the risk of fever, enhanced phototherapy does not increase other adverse reactions.

[0006] Long-term exposure of blue light to the retina can cause photochemical damage, leading to eye discomfort, and in severe cases, can cause a variety of retinal diseases. When blue light therapy is performed on children, in order to reduce the light stimulation of blue light to the eyes of medical staff and children in adjacent beds, a phototherapy cover cloth is routinely placed on the outside of the phototherapy box. Traditional phototherapy cover cloths are usually blackout cloths that cover the entire transparent part of the phototherapy box. During phototherapy, sufficient light cannot be guaranteed in the phototherapy box, affecting the various operations performed by nursing staff. Therefore, the cover cloth needs to be lifted for each nursing operation, and the cloth material is light and easy to fall to the ground. Frequent and repetitive actions not only increase the workload of nursing staff, reduce work efficiency, but also increase the chance of infection. In addition, traditional phototherapy cover cloths need to be sent out for cleaning, disinfection, and drying after use, which consumes a lot of time and economic costs. Utility Model Content

[0007] The purpose of the utility model is to provide a phototherapy cover cloth for a blue light box, which can improve the phototherapy effect, facilitate nursing operations, reduce the risk of infection, and enhance the stability and safety of use.

[0008] The technical solution adopted by the present invention to solve the above problems is: a phototherapy cover cloth for a blue light box, comprising a top cloth and four side cloths, the side cloths comprising a light-transmitting portion and a light-reflecting portion, the light-reflecting portion comprising a fixed portion and a movable portion, the fixed portion being arranged below the light-transmitting portion, the movable portion being connected to the light-transmitting portion in a damped sliding manner, and the movable portion being adapted to be equipped with a driving component that drives it to slide and block the light-transmitting portion.

[0015] Preferably, two sides of the side cloth are provided with frames, the frames are provided with magnetic parts, and the magnetic parts between adjacent side cloths attract each other.

[0016] Compared with the prior art, the present invention has the following advantages and effects:

[0017] The side cloth of this utility model adopts a double-layer translucent structure, in which a reflective layer is sandwiched between the two translucent layers of the reflective portion. This effectively reflects the blue light that passes through the translucent portion and returns it to the treatment area of ​​the blue light box, thereby increasing the intensity and uniformity of phototherapy, accelerating the reduction of serum bilirubin levels, and shortening treatment time. The reflective portion includes a fixed portion and a movable portion. The fixed portion is located below the translucent portion, allowing caregivers to observe the condition of the child in the blue light box through the translucent portion without lifting the side cloth, significantly reducing the number of times the cover cloth needs to be lifted, thereby reducing the nursing workload. In addition, the movable part is connected to the light-transmitting part in a damping sliding manner, and the movable part is adapted to be equipped with a driving component that drives it to slide and block the light-transmitting part. The driving component drives the movable part to block the light-transmitting part, and adjusts the size of the light-transmitting area of ​​the light-transmitting part or the reflective area of ​​the reflective part. It can also achieve complete shading of the side cloth (the light-transmitting part is completely blocked by the movable part), thereby avoiding the impact of blue light leakage on clinical children. At this time, the side cloth has a larger reflective area, which reduces the waste caused by blue light overflow and is more helpful for the treatment of children. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] Example:

[0027] See also Figure 1 - Figure 5 In this embodiment, a phototherapy cover cloth for a blue light box 1 is provided, which is specifically used for blue light treatment of neonatal hyperbilirubinemia. The cover cloth specifically comprises: a top cloth 2 and four side cloths 3. The side cloth 3 comprises a light-transmitting portion 31 and a light-reflecting portion 32. The light-reflecting portion 32 comprises a fixed portion 321 and a movable portion 322. The fixed portion 321 is arranged below the light-transmitting portion 31. The movable portion 322 is connected to the light-transmitting portion 31 in a damped sliding manner, and the movable portion 322 is adapted to be equipped with a driving component 33 for driving the movable portion 322 to slide and block the light-transmitting portion 31.

[0028] Specifically, in this embodiment, the translucent portion 31 of the side cloth 3 is positioned above the reflective portion 32. This ensures that during phototherapy, while minimizing blue light exposure to the eyes of medical staff and children in adjacent beds, caregivers can observe the condition of the child within the blue light box 1 through the transparent portion without lifting the side cloth 3. This significantly reduces the need to frequently lift the cloth, thereby reducing nursing workload. Since medical staff are less likely to come into contact with the phototherapy cover, the risk of cross-infection is also reduced. Furthermore, the drive component 33 drives the movable portion 322 to slide, causing it to (partially) block the translucent portion 31. This not only changes the area of ​​the translucent portion 31, but also completely blocks the side cloth 3 when the translucent portion 31 is completely blocked, preventing the effects of blue light leakage on the child. In this case, the side cloth 3 has a larger reflective area, reducing the waste caused by blue light leakage and further facilitating treatment for the child. In this embodiment, the drive component 33 is a handle that medical staff can grasp and pull to slide the movable portion 322.

[0029] See also Figure 4 and Figure 5In this embodiment, the side cloth 3 adopts a double-layer light-transmitting layer 41 structure, wherein a reflective layer 42 is sandwiched between the double-layer light-transmitting layers 41 of the reflective portion 32. The reflective layer 42 can reflect the blue light that passes through the inner light-transmitting layer 41 of the reflective portion 32 back to the treatment area of ​​the blue light box 1, thereby improving the phototherapy effect and helping to reduce the serum bilirubin level more quickly. The top cloth 2 and the side cloth 3 are connected by an openable connector 5 such as a hinge, Velcro, or a fastener. The openable connector 5 in this embodiment adopts a plurality of groups of flexible connecting strips, the ends of which are respectively connected and fixed to the top cloth 2 and the side cloth 3 by a detachable method such as a Velcro structure, magnetic adsorption, snap, or bonding. The connecting strip adopts an elliptical outline, and the two ends of the long axis of the ellipse are connected to the top cloth 2 and the side cloth 3. The flexible connecting strip in this embodiment adopts a detachable design. It is disposable and can be replaced regularly, ensuring the cleanliness and hygiene of the connecting strip 5 during use, extending the service life of the phototherapy cover cloth, and reducing maintenance costs.

[0030] In this embodiment, the top cloth 2 and the light-transmitting layer 41 are made of PVC material, which has excellent light transmittance, durability, and easy cleaning. The use of transparent PVC material allows blue light to pass through while also having a certain degree of flexibility, making it suitable for the structural design of a phototherapy cover cloth. The reflective layer 42 is made of tinfoil or aluminum foil, which has excellent reflective properties. Tinfoil and aluminum foil can efficiently reflect blue light, allowing more blue light to be reflected back into the phototherapy box, improving the phototherapy effect and achieving the goal of faster lowering serum bilirubin levels.

[0031] See also Figure 6 In this embodiment, a frame 34 is provided on both sides of the side cloth 3, and a magnetic part 6 is provided on the frame 34. The magnetic parts 6 between adjacent side cloths 3 attract each other. The frame 34 is provided with a guide groove 341, and the two sides of the movable part 322 are adapted to the damping sliding connection of the guide groove 341, so that the movable part 322 can be fixed at various positions on the frame 34. In this embodiment, a magnet is used as the magnetic part 6, and the magnetic part 6 provides an additional fixing force to the side cloth 3, so that the edges of the four side cloths 3 are sequentially fitted under the action of the magnetic part 6, so that the cover cloth is put on the blue light box 1 as a whole, which can prevent the side cloth 3 from falling off due to nursing operations or external interference during use, thereby ensuring the stability of the phototherapy process. At the same time, it can effectively reduce the light leakage at the seams of the phototherapy cover cloth, ensure the light intensity in the phototherapy area, and improve the phototherapy effect.

[0032] The above contents described in this specification are merely examples of the present invention. Those skilled in the art of the present invention may make various modifications, additions, or substitute similar methods to the specific embodiments described, as long as they do not deviate from the contents of this specification or exceed the scope defined by the claims, and shall fall within the scope of protection of the present invention.
