Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a phototherapy light shield. Background Art

[0002] Phototherapy is a physical therapy method that uses the radiant energy of light to treat diseases. Phototherapy mainly includes ultraviolet therapy, visible light therapy, infrared therapy, and laser therapy. Infrared rays act on the human body to mainly improve local blood circulation, promote the subsidence of swelling, relieve pain, reduce muscle tension, relieve muscle spasm, and dry exudative lesions.

[0003] When ultraviolet rays act on the human body, the light energy causes a series of chemical reactions, which have the effects of anti-inflammatory, analgesic, and anti-rickets. It is commonly used to treat suppurative skin inflammation and other dermatitis, pain syndromes, rickets or osteomalacia, etc.; ultraviolet rays in the wavelength range of 310 - 313 nm are called narrow-band medium-wave ultraviolet rays (NBUVB), which concentrate the most biologically active part of ultraviolet rays and directly act on the affected skin area, while filtering out the harmful ultraviolet rays in the adverse wavelength bands, with small side effects, acting on the stratum corneum of the skin, and having a short onset time and quick effect. It has been widely used in major hospitals for the treatment of diseases such as psoriasis, vitiligo, chronic eczema, neurodermatitis, atopic dermatitis, palmoplantar pustulosis, pityriasis rosea, alopecia areata, parapsoriasis, chronic skin ulcers, mycosis fungoides, etc.

[0004] Visible light is the light that can be seen by the human eye. The method of using visible light to treat diseases is visible light therapy. It mainly includes red light, blue light, blue-violet light, and multi-spectral therapy. Red light has an excitatory effect; yellow light and green light have the opposite effect to red light; blue-violet light can be used to treat kernicterus.

[0005] Laser is the light generated by the stimulated emission of light amplification, which has the characteristics of small divergence angle, good directivity, pure spectrum, good monochromaticity, high energy density, high brightness, and good coherence, and has thermal effect, mechanical effect, and electromagnetic effect. It can be used for the diagnosis and treatment of many diseases.

[0006] Currently, during phototherapy, props are needed to cover the areas other than the treatment site to prevent the normal skin from turning black after treatment. However, since the shapes and areas of the treatment sites required by each patient are different, the current auxiliary tools are all fixed molds and are difficult to adjust according to the actual situation.

[0009] Furthermore, the outer layer, the light blocking layer and the contact layer have the same thickness.

[0010] Furthermore, the light blocking layer is made of a light blocking material.

[0011] Furthermore, the contact layer is made of a silica gel material.

[0031] Embodiment 1

[0032] As Figures 1-4 shown, a phototherapy light shield includes a light-shielding plate; the light-shielding plate is in a plate-like structure; the light-shielding plate has a flange, a concave edge and a straight edge; the light-shielding plate includes an outer layer 1, a light-shielding layer 2 and a contact layer 3; one side of the light-shielding layer 2 is fixedly connected to the outer layer 1, and the other side is fixedly connected to the contact layer 3; a first anti-slip structure 11 is provided on the side of the outer layer 1 away from the light-shielding layer 2; a second anti-slip structure 31 is provided on the side of the contact layer 3 away from the light-shielding layer 2.

[0033] During use, a plurality of light-shielding plates are arranged around the outer side of the treatment site required by the patient to form an annular light-impermeable layer to prevent normal skin from being irradiated; according to the shape of the treatment site required by the patient, the flange, concave edge or straight edge of the light-shielding plate can be freely selected to face the patient, which can quickly adapt to all patients and is convenient for use.

[0034] Specifically, the outer layer 1, the light-shielding layer 2 and the contact layer 3 have the same thickness.

[0035] The light-shielding layer 2 is made of a light-shielding material to prevent the treatment light from passing through the light-shielding layer 2.

[0036] Specifically, the light-shielding material is one or more of linen light-shielding cloth, flame-retardant light-shielding cloth, and physical black light-shielding cloth.

[0037] Specifically, the color of the light-shielding layer 2 is black.

[0038] The contact layer 3 is made of a silicone material. The texture of the silicone material is close to that of human skin. When the contact layer 3 made of the silicone material contacts the patient's skin, it can reduce the discomfort of the patient.

[0039] The second anti-slip structure 31 is an anti-slip dot matrix. The anti-slip dot matrix protrudes from the surface of the contact layer 3. The material of the anti-slip dot matrix is the same as that of the contact layer 3, and both are made of a silicone material.

[0040] The outer layer 1 is made of a silicone material. When a plurality of light-shielding plates are arranged around the outer side of the treatment site required by the patient, the side of the outer layer 1 away from the light-shielding layer 2 will contact the contact layer 3 on other light-shielding plates. Since both the contact layer 3 and the outer layer 1 are made of a silicone material, they can fit together to a certain extent to prevent the plurality of light-shielding plates from shifting relative to each other.

[0041] Specifically, the silicone material is one or more of solid silicone rubber and liquid silicone.

[0042] Furthermore, the first anti-slip structure 11 is an anti-slip pattern. The anti-slip pattern protrudes from the surface of the outer layer 1. When the outer layer 1 contacts the contact layer 3 on other light-shielding plates, the anti-slip dot matrix will enter the gap between the anti-slip patterns, further enhancing the friction between the plurality of light-shielding plates to apply the friction to limit the positional relationship between adjacent light-shielding plates.

[0043] In some embodiments of the present application, the outer layer 1 and the contact layer 3 enclose a sealed cavity structure; the light-shielding layer 2 is located inside the cavity structure.

[0044] Example 2

[0045] As Figures 5-6 shown, the difference between this embodiment and Embodiment 1 is that:

[0046] The second anti-slip structure 31 is an adhesive layer. When the adhesive layer contacts the patient's skin, it will adhere to the patient's skin. When the adhesive layer contacts the outer layer 1 on other light-shielding plates, it will adhere to the outer layer 1. Thus, multiple light-shielding plates can be arranged around the outside of the patient's treatment area.

[0047] The above are only the specific embodiments of the present application. Under the above teachings of the present application, those skilled in the art can make other improvements or deformations based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of the present application, and the protection scope of the present application should be subject to the protection scope of the claims.
