[0002] Jaundice treatment devices use photocatalysis of specific wavelengths to convert bilirubin, safely and effectively reducing bilirubin levels in newborns, making them the preferred method for treating neonatal hyperbilirubinemia.

[0003] In practical use, because newborns have poor self-control and cannot keep their eyes closed for a long time, the light from the light source component of the jaundice treatment device will enter the newborn's eyes, causing retinal damage. In existing technologies, the problem of retinal damage is often solved by having the newborn wear an eye patch.

[0004] However, in actual treatment, the applicant of this application discovered the following problems:

[0005] Wearing an eye mask can reduce the comfort of the child, interfere with their sleep, and cause them to cry incessantly due to stress, thus interrupting the treatment and affecting its effectiveness.

[0006] Wearing an eye patch creates a dark environment for the patient, increasing the child's fear and causing them to grab the eye patch, which can lead to it falling off and causing retinal damage. In addition, bright light can make the child irritable, have difficulty falling asleep, cry frequently, and affect the treatment process.

[0007] In conclusion, how to address the problem of retinal damage caused by light easily entering the eyes of infants during phototherapy for neonatal jaundice is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] The core of this invention is to provide a light-shielding component that uses quantum dot filtering to convert the harmful light from the jaundice treatment device into light that is harmless to the child's retina. This eliminates the need for the child to rely on an eye mask to avoid the light from the jaundice treatment device and prevents damage to the retina caused by the child's stress and crying during treatment.

[0051] Another core aspect of this invention is to provide a neonatal jaundice treatment device that includes the aforementioned light-shielding components, possessing the same technical features and capable of solving the same technical problems.

[0052] Please refer to Figure 1 A light-shielding component for blocking blue light emitted by a neonatal jaundice treatment device to prevent blue light from shining directly into the patient's eyes;

[0053] The light-shielding components, from the outside to the inside, include:

[0054] The outer protective layer is made of flexible polymer material;

[0055] The quantum dot filter layer of PDMS matrix has a gradient distribution of perovskite quantum dots.

[0056] The light-guiding and reflecting layer contains a micro-prism array to reflect external light into the quantum dot filter layer.

[0057] The inner protective layer is made of skin-friendly material.

[0058] The outer layer of the light-shielding component 2 is a flexible polymer material protective layer that can block some ambient light, reduce the impact of ambient light on the filtering of harmful light, and at the same time, provide protection to prevent physical damage to the internal structure.

[0059] The light-shielding component 2 uses PDMS material as the matrix of the quantum dot filter layer, which gives the light-shielding component 2 a high elasticity and ensures the stability of the optical performance when the light-shielding component 2 is deformed; and perovskite quantum dots are embedded inside, and the dispersion density of the quantum dots is trapezoidal, which reduces the loss of self-absorption.

[0060] Meanwhile, the dispersion density of quantum dots near the light-injecting side of the quantum dot filter layer is greater than that near the light-out side. This increases the probability of light binding and excitation with quantum dots when it enters, reducing the light transmittance. Furthermore, the transmitted light can be reflected by the light-guiding and reflecting layer and re-enter the quantum dot filter layer. The reflected light first passes through the low-density quantum dot region and then binds and excites with the high-density quantum dot region, thereby reducing the self-absorption loss of the quantum dot filter layer.

[0061] The light-guiding and reflecting layer of the light-shielding component 2 is a flexible microprism array manufactured using nanoimprint technology. It reflects blue light that has passed through the quantum dot filter layer back to the quantum dot filter layer for excitation of the quantum dots, converting blue light into green light and reducing the blue light transmittance of the light-shielding component 2.

[0062] The inner protective layer of the light-shielding component 2 is made of skin-friendly fabrics such as silk, lubricated fabric, and medical elastic non-woven fabric, which helps to improve the comfort of the child and protect the internal structure of the light-shielding component 2 from physical damage.

[0063] In some embodiments, a magnetic frame 23 is also included, which is disposed at the edge of the light-shielding component and is used to attach and fix the light-shielding component to the neonatal jaundice treatment device.

[0064] like Figure 1As shown, the magnetic frame 23 uses medical silicone to encapsulate the magnet, which attaches and fixes the light-shielding component 2 to the neonatal jaundice treatment device to block blue light. This eliminates the need for physical straps and improves ease of use.

[0065] In some embodiments, a U-shaped ring 21 is also included, which is fixedly connected to the inner protective layer or bottom edge of the light-shielding assembly for snapping onto the patient's neck to seal the gap between the patient and the light-shielding assembly.

[0066] like Figure 1 As shown, by adding a U-shaped ring 21, which is snapped onto the patient's neck, the problem of light leakage caused by uneven contact between the light-shielding component 2 and the patient is solved.

[0067] In some embodiments, the U-shaped ring 21 includes a skin-friendly surface layer, a soft silicone filling layer, and an air bladder 22 placed inside it. The air bladder 22 is connected to an air source device through an air tube and is used to adjust the fit between the U-shaped ring 21 and the patient's neck by adjusting the pressure inside the air bladder 22.

[0068] The U-shaped ring 21 uses a skin-friendly surface layer and a soft silicone filling layer to improve the comfort of the child; at the same time, it integrates an airbag 22 inside. By adjusting the gas pressure inside the airbag 22, the curvature of the U-shaped ring 21 can be adjusted so that it can fit the curve of the child's neck to the greatest extent and make up for the light leakage at the contact point between the light-shielding component 2 and the child.

[0069] In addition to the light-shielding components disclosed in the above embodiments, this utility model also provides a neonatal jaundice treatment device including the above-mentioned light-shielding components, the neonatal jaundice treatment device further comprising:

[0070] Placement compartment 3, with an open top, is used to place the patient;

[0071] The light source component 4 is positioned above the placement chamber 3 and connected to the placement chamber 3 via a lifting bracket 5. The light shielding component 2 is positioned between the light source component 4 and the patient's eyes inside the placement chamber 3 to prevent light from the light source component 4 from entering the patient's eyes inside the placement chamber 3.

[0072] like Figure 2 As shown, the light source component 4 is suspended and installed on the top of the placement chamber 3. In use, the child is placed inside the placement chamber 3, and the light shielding component 2 is placed between the child's eyes and the light source component 4. At this time, the light source component 4 is activated, and the light shines on the child's body for treatment. The light shining on the eyes is blocked and filtered by the light shielding component 2 and converted into harmless green light. At this time, the child does not need to rely on an eye mask, which will not affect the comfort of the child's eyes, nor will it put the child in a dark and frightening environment. This helps the child to accept the treatment peacefully, so as to ensure the treatment effect.

[0073] In some embodiments, a distance sensor 41 is provided below the light source assembly 4 to detect the distance between the light source assembly 4 and the patient in the placement chamber 3, and to control the lifting bracket 5 to adjust the distance between the light source assembly 4 and the patient in the placement chamber 3 according to the detection result.

[0074] In actual treatment, the distance between the light source component 4 and the child directly affects the treatment effect of jaundice. In existing technologies, the adjustment of this distance largely depends on the experience of medical staff, and the adjustment precision is limited. This application adopts a method such as... Figure 2 As shown, a distance sensor 41, such as an infrared ranging sensor, is installed inside the light source assembly 4 to measure the distance between the light source assembly 4 and the child in a non-contact manner, and drives the lifting bracket 5 to adjust the suspension height of the light source assembly 4 to change the distance between the light source assembly 4 and the child. With the help of pre-stored data, the distance between the light source assembly 4 and the child can be accurately controlled to ensure the treatment effect.

[0075] In some embodiments, the lifting bracket 5 includes a fixed end and a lifting end that slide relatively vertically, and a push rod motor for driving the relative movement of the two is provided between the fixed end and the lifting end.

[0076] The fixed end is fixedly connected to the placement chamber 3, and the lifting end is fixedly connected to the light source assembly 4.

[0077] A vertical slide rail is provided between the fixed end and the lifting end to ensure stable relative movement between the two. The internal push rod motor drives the relative movement between the two to adjust the distance between the light source component 4 and the child.

[0078] In actual use, an infusion stand is fixedly installed on the outside of the fixed end to suspend the infusion bottle, so that the child can receive infusion at the same time during phototherapy.

[0079] In some embodiments, a base 1 is provided at the bottom of the placement compartment 3;

[0080] A wheeled walking assembly is installed below the base 1;

[0081] And / or,

[0082] The base 1 is equipped with a storage box 11 and / or a storage rack.

[0083] like Figure 2 As shown, a base 1 with wheeled walking components is provided at the bottom of the placement compartment 3 to facilitate the overall movement of the equipment;

[0084] Meanwhile, a storage box 11 and / or a shelf are provided inside the base 1 for the temporary storage of items.

[0085] In some embodiments, a guardrail 31 is provided at the edge of the upper open position of the placement chamber 3 to prevent the patient from falling;

[0086] And / or,

[0087] The storage compartment 3 is equipped with a handle 32 on the outside.

[0088] like Figure 2 As shown, by setting up a guardrail 31 at the open position of the placement chamber 3, the child is prevented from falling.

[0089] Meanwhile, a handle 32 is installed on the outside of the placement chamber 3 to facilitate medical staff to push the device.
