Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a modular facial shading cloth. Background Technology

[0002] Vitiligo is a common acquired skin and mucous membrane disease characterized by depigmentation, which can affect hair follicles and clinically manifests as white patches or / and gray hair. Its pathogenesis is complex and may be related to multiple factors such as autoimmunity, genetics, neuropsychiatric factors, and oxidative stress. Patients experience a loss of melanocyte function in their skin, resulting in white patches of varying sizes and shapes appearing across the body. These white patches affect appearance, causing psychological stress for patients and may be accompanied by other autoimmune diseases. 308 nm excimer laser therapy is a commonly used and effective treatment for vitiligo. The 308 nm excimer laser emits high-energy ultraviolet light with a single wavelength of 308 nm. This specific wavelength of light can induce T lymphocyte apoptosis, and abnormal T lymphocytes play a crucial role in the pathogenesis of vitiligo. This therapy regulates local immune function, promotes the proliferation and migration of melanocytes, allowing melanocytes to grow and produce melanin in the white patches, accelerating pigment recovery and achieving the goal of treating vitiligo. Meanwhile, this treatment method is highly targeted, able to precisely act on the vitiligo area, has a fast onset of action, a short treatment course, high safety, and relatively few side effects. It can also effectively treat special areas such as the face and mucous membranes. Therefore, 308 irradiation is often used in clinical practice to treat vitiligo patients.

[0003] A practical problem exists when using 308nm excimer laser therapy to treat facial vitiligo. Because the size of the 308nm excimer laser head is limited, it's difficult to precisely target only the vitiligo areas during operation, inevitably resulting in the irradiation of surrounding normal skin. This normal skin will darken after 308nm excimer laser treatment. Facial vitiligo patients are extremely concerned about their appearance, and any subtle changes will be particularly noticeable. The darkening of normal skin due to irradiation severely affects the overall aesthetics of the face, causing significant psychological distress for patients and becoming a key issue that needs to be addressed during 308nm excimer laser treatment.

[0004] Therefore, those skilled in the art have provided a modular face shielding fabric to address the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular face shielding cloth. The modular design allows for easy adjustment and provides high shielding efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A modular face shielding fabric includes a non-woven fabric with a textured surface and multiple shielding fabrics. The shielding fabrics include an outer aluminum foil fabric, a middle lead rubber fabric at the rear end of the outer aluminum foil fabric, an inner gauze fabric at the rear end of the middle lead rubber fabric, and a Velcro hook at the rear edge of the inner gauze fabric.

[0008] Furthermore, elastic restraint straps are fixedly provided at the upper and lower parts of the rear end of the nonwoven fabric.

[0009] Furthermore, the front end of the nonwoven fabric is designed to be attached to the hook and loop fastener.

[0010] Furthermore, the outer aluminum foil cloth, the middle lead rubber cloth, the inner gauze, and the Velcro hook are sewn or pressed together for fixation.

[0011] Furthermore, the nonwoven fabric frame is designed with a shape that conforms to the human face.

[0012] This utility model has the following beneficial effects:

[0013] This invention proposes a modular facial shading cloth. Its modular design allows users to flexibly adjust the position of the shading cloth according to treatment needs, ensuring that only the vitiligo areas receive 308 irradiation, preventing normal skin from darkening due to irradiation, thus improving treatment accuracy and patient comfort. The shading cloth adopts a multi-layer structure, including an outer aluminum foil cloth, a middle lead rubber cloth, and an inner gauze, ensuring efficient shading and safe use. Elastic straps can firmly fix the mask to the patient's head, ensuring that the mask will not shift during treatment, while also considering patient comfort. The Velcro design makes the installation and removal of the shading cloth very convenient, allowing users to quickly adjust the shading area as needed. The non-woven fabric with a frame design and a shape that conforms to the face ensures that the mask fits the patient's face tightly, preventing light leakage from gaps and further improving the shading effect.

[0020] 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.

[0021] Reference Figures 1-4 An embodiment of this utility model is provided: a modular face shielding cloth, including a non-woven fabric 2 and multiple shielding fabrics 1. The shielding fabric 1 includes an outer aluminum foil cloth 101, a middle lead rubber cloth 102 is provided at the rear end of the outer aluminum foil cloth 101, an inner gauze cloth 103 is provided at the rear end of the middle lead rubber cloth 102, and a Velcro hook side 104 is provided at the rear edge of the inner gauze cloth 103.

[0022] Elastic restraint straps 3 are fixedly installed at the upper and lower rear ends of the non-woven fabric 2. The front end of the non-woven fabric 2 is designed to be attached to the hook and loop fastener 104. The outer aluminum foil fabric 101, the middle lead rubber fabric 102, the inner gauze fabric 103, and the hook and loop fastener 104 are sewn or pressed together for fixation. The non-woven fabric 2 has a frame design and its shape conforms to the human face.

[0023] Specifically, the modular design of this technology allows users to flexibly adjust the position of the masking fabric according to treatment needs. By tearing or attaching different masking fabrics 1, the irradiation area can be precisely controlled, ensuring that only the vitiligo areas receive 308 irradiation and preventing normal skin from darkening due to irradiation. This design greatly improves the precision of treatment and patient comfort. The masking fabric 1 adopts a multi-layer structure, including an outer aluminum foil fabric 101, a middle lead rubber fabric 102, and an inner gauze 103. The outer aluminum foil fabric 101 has high reflectivity and can effectively reflect ultraviolet rays; the middle lead rubber fabric 102 has high density and can effectively block ultraviolet rays from penetrating; the inner gauze 103 provides a comfortable touch and avoids irritating the patient's skin. This multi-layer structure ensures the high efficiency of light blocking and the safety of use. Elastic restraint straps 3 are fixedly installed at the upper and lower rear ends of the non-woven fabric 2. These restraint straps can firmly fix the mask to the patient's head, ensuring that the mask will not shift during treatment, thereby ensuring the light blocking effect. Meanwhile, the elastic restraint band 3 is designed with patient comfort in mind, avoiding being too tight or too loose. The inner gauze 103 has a Velcro hook 104 at its rear edge, which fits snugly against the front of the non-woven fabric 2, making the installation and removal of the masking fabric 1 very convenient. This design not only improves ease of use but also allows users to quickly adjust the coverage area as needed. The non-woven fabric 2 features a frame design shaped to fit the face, ensuring a tight fit and preventing light leakage, further enhancing the light-blocking effect. The frame design also makes the mask lighter, reducing the burden on the patient.

[0024] Working principle: Before treatment, elastic restraint straps 3 are first placed on the patient's head to ensure that the non-woven fabric 2 is firmly attached to the patient's face. Then, according to the area to be treated, the corresponding covering fabric 1 is torn off, and the instrument can be used for treatment. Other areas are still covered by the covering fabric 1. During the treatment, healthy areas will not be irradiated to avoid darkening. If the area to be treated is blocked by the non-woven fabric 2, the position or angle of the mask can be slightly adjusted to allow it to be used in any location. This mask has a simple structure and is made of inexpensive materials. Depending on the needs, it can be used as a disposable medical device or reused after being sterilized at high temperature.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
