Description

Technical Field

[0001] This invention primarily relates to the field of daily travel products for infants and toddlers and auxiliary medical care technologies. More specifically, this invention relates to a stroller with a neonatal jaundice phototherapy function. Background Technology

[0002] Neonatal jaundice is one of the most common clinical symptoms in newborns. It is mainly caused by abnormal bilirubin metabolism, leading to elevated levels of unconjugated bilirubin in the blood, which then deposits on the skin, mucous membranes, and sclera, resulting in a yellow color. If pathological jaundice is not treated promptly, high concentrations of bilirubin may cross the blood-brain barrier, causing permanent damage to the nervous system.

[0003] Currently, phototherapy is recognized in clinical medicine as the most effective and safest treatment. Its principle is to use light of a specific wavelength to cause a photochemical reaction in bilirubin molecules, converting them into water-soluble isomers that can be directly excreted without liver metabolism. However, existing hospital phototherapy units can lead to mother-infant separation, which is detrimental to breastfeeding and the establishment of parent-child bonding; while home-use phototherapy blankets or lamps are bulky and entirely powered, limiting the child's range of motion and making them unsuitable for outdoor use.

[0004] Furthermore, although sunlight naturally contains blue light, which is effective in treating jaundice, direct exposure to sunlight poses significant risks to newborns. Sunlight contains a large amount of ultraviolet radiation, which can easily damage a newborn's delicate skin; at the same time, the infrared and long-wave visible light in sunlight produce a significant thermal effect, easily leading to hyperthermia or dehydration in newborns. Existing stroller sunshades mainly focus on shading, usually blocking both beneficial blue light and harmful ultraviolet radiation, failing to achieve the optimal utilization of natural light.

[0005] Therefore, there is an urgent need to develop an innovative stroller that can combine outdoor walking with jaundice treatment, requires no power source, and can safely filter natural light. Summary of the Invention

[0006] The present invention aims to solve the technical problems of natural light therapy for jaundice, such as the high risk of ultraviolet damage and significant thermal effects, as well as the limitations of traditional phototherapy equipment in terms of range of motion and dependence on power supply.

[0007] To achieve the above objectives, the present invention provides a stroller with neonatal jaundice phototherapy function, including a frame, a seat mounted on the frame, and a light barrier assembly disposed above the seat. The light barrier assembly is provided with a blue light selective transmission layer, which is configured to spectrally filter natural light or ambient light irradiating the stroller.

[0008] The spectral screening has bandpass filtering characteristics, specifically: it allows therapeutic wavelengths in the range of 400nm to 550nm to pass through; it blocks or attenuates ultraviolet light with wavelengths less than 400nm and visible and infrared light with wavelengths greater than 550nm. The light passing through the light barrier component creates a phototherapy environment within the cabin that aids in jaundice reduction.

[0009] Furthermore, the light barrier assembly includes a sunshade assembly or a transparent protective cover assembly. When it is a sunshade assembly, it is made of fabric or flexible composite material, and the blue light selective transmission layer is attached to the surface of the fabric fibers, in the interlayer, or connected to the sunshade assembly as a separate detachable cover; when it is a transparent protective cover assembly, it is made of transparent polymer material, and the blue light selective transmission layer is incorporated into the surface or substrate of the transparent protective cover assembly.

[0010] Furthermore, the optical parameters for the spectral screening meet the following requirements: in the therapeutic wavelength range of 400nm to 550nm, the average light transmittance is higher than 80%; in the ultraviolet wavelength range of 200nm to 400nm, the average light transmittance is lower than 1%; and in the visible light wavelength range of 500nm to 780nm, the average light transmittance is lower than 30%.

[0011] Furthermore, the blue light selective transmission layer includes an optical coating structure fabricated using the principle of interference. The optical coating structure comprises alternating layers of high-refractive-index material and low-refractive-index material; the optical coating structure is configured to utilize the principle of thin-film interference to cause constructive interference of light in the wavelength range of 400nm to 550nm to enhance transmission, while causing destructive interference or reflection of visible light and ultraviolet light outside this range to achieve blocking or attenuation.

[0012] Furthermore, the blue light selective transmission layer also includes a light energy conversion material. The light energy conversion material is configured to absorb ultraviolet light with wavelengths less than 450 nm and to emit fluorescence with wavelengths in the range of 400 nm to 550 nm upon stimulation; the light energy conversion material is combined with the optical coating structure to further enhance the light intensity of the therapeutic band.

[0013] Furthermore, when the light barrier component is a flexible awning component, the optical coating structure is deposited on a flexible transparent substrate by low-temperature magnetron sputtering or electron beam evaporation, and then the flexible transparent substrate is composited at the light-transmitting window of the awning component.

[0014] The present invention has the following beneficial effects: by using physical light filtering methods, harmful ultraviolet rays and infrared bands that cause thermal effects in natural light are precisely eliminated, and only specific blue light that is effective in decomposing bilirubin is retained, so that infants can receive safe light therapy while walking outdoors; the device does not rely on an external power source, is energy-saving and environmentally friendly and easy to use, and effectively solves the problem of mother-infant separation caused by traditional phototherapy.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Example 1:

[0024] Please see Figure 1 This embodiment provides a stroller 100 with neonatal jaundice phototherapy function. The stroller 100 mainly includes a frame 10, a seat 20, and a light barrier assembly 30.

[0025] The frame 10 serves as the main support for the stroller 100, and is equipped with wheels at the bottom for mobility. The seat 20 is mounted on the frame 10 and is used to accommodate the infant. A light barrier assembly 30 is disposed above the seat 20 to cover the light-receiving area of ​​the seat 20. In this embodiment, the light barrier assembly 30 is a foldable sunshade structure, and its surface is provided with a blue light selective transmittance layer 31 (see...). Figure 2 When the light barrier assembly 30 is deployed, external light must pass through the blue light band selective transmission layer 31 to enter the interior of the cockpit 20.

[0026] Through the aforementioned structure, a passive light-nursing environment is created inside the cabin 20. This environment utilizes natural light resources to provide continuous and gentle adjunctive treatment for jaundice in infants without the need for power.

[0027] Example 2:

[0028] Please see Figure 2 This demonstrates the optical screening principle and microstructure of the light barrier component 30.

[0029] When natural light shines on the surface of the light barrier component 30, the blue light selective transmission layer 31 sorts the light according to different wavelengths. As shown in the figure, natural light includes ultraviolet A (wavelength less than 400nm), therapeutic light B (wavelength 400nm to 550nm), and other visible light and infrared light C (wavelength greater than 550nm).

[0030] The blue light selectively permeable layer 31 is configured to block ultraviolet A. When ultraviolet A comes into contact with the surface of the permeable layer, it is reflected or absorbed, preventing it from penetrating into the cabin and thus protecting the infant from ultraviolet burns. In this embodiment, the blocking rate of ultraviolet A is preferably greater than 99%.

[0031] The blue light selective transmission layer 31 is configured to transmit high-flux therapeutic wavelength light B. This wavelength covers the bilirubin absorption peak and its surrounding effective area. Figure 2 As indicated by the middle arrow, the therapeutic wavelength light B penetrates the transmissive layer and enters below, forming a therapeutic light field within the cabin. In this embodiment, the average transmittance of the therapeutic wavelength light B is preferably higher than 80%.

[0032] The blue light selective transmittance layer 31 is also configured to block other visible light and infrared light C. The light C is reflected back to the external environment, thereby filtering out ineffective strong light and heat-generating infrared rays, preventing the cabin temperature from becoming too high, and maintaining a comfortable physical environment.

[0033] Example 3:

[0034] Please continue reading. Figure 2 This embodiment describes the specific material structure of the blue light selective transmission layer 31. The transmission layer is a layered composite structure, including a flexible transparent substrate 32, an optical coating structure 311, and a light energy conversion material 312.

[0035] The flexible transparent substrate 32 is made of a flexible polymer material with high light transmittance, such as polyethylene terephthalate or thermoplastic polyurethane film, which serves as the physical carrier for subsequent functional layers and is laminated to the light-transmitting window of the awning.

[0036] An optical coating structure 311 is deposited on a flexible transparent substrate 32. The optical coating structure 311 comprises alternating stacked layers of high-refractive-index and low-refractive-index materials. The high-refractive-index material layers can be selected from materials such as titanium dioxide and tantalum pentoxide; the low-refractive-index material layers can be selected from materials such as silicon dioxide and magnesium fluoride. By precisely controlling the physical thickness of each film layer, the optical coating structure 311 utilizes the principle of thin-film interference to cause constructive interference of light with wavelengths in the range of 400nm to 550nm at the interface, thereby enhancing transmission; simultaneously, it causes destructive interference or reflection of light outside this range.

[0037] To accommodate the temperature resistance of the flexible transparent substrate 32, the optical coating structure 311 is formed by low-temperature magnetron sputtering or electron beam evaporation, which ensures that the film layer is dense and does not easily fall off when the substrate is bent.

[0038] Furthermore, to further improve light energy utilization, the blue light selective transmission layer 31 is also doped with a light energy conversion material 312. The light energy conversion material 312 is distributed between layers or on the surface of the optical coating structure 311. This material is selected from phosphors or quantum dots with down-conversion properties. Figure 2 As shown, some of the incident ultraviolet A is absorbed by the light energy conversion material 312, and the light energy conversion material 312, after being excited, emits fluorescence with a wavelength in the range of 400nm to 550nm. This process not only further absorbs harmful ultraviolet light, but also converts the originally useless ultraviolet energy into beneficial therapeutic light B, thereby increasing the light intensity transmitted through the component.

[0039] In summary, the present invention achieves safe screening and utilization of natural light by setting a blue light selective transmission layer 31 on the light barrier component 30 of the stroller 100 and utilizing the synergistic effect of the optical coating structure 311 and the light energy conversion material 312.
