Description

Patch phototherapy device

The present invention relates to a photodynamic therapy device, in particular to a patch-type phototherapy device.

It is currently known that light of different wavelengths can achieve different repair effects on the skin. When light of different wavelengths is irradiated on the human body, light of specific wavelengths can promote skin wound healing, and light of specific wavelengths can relieve skin sensitivity symptoms, even long wavelengths. The light can stimulate muscle repair and achieve rehabilitation effects, and this phototherapy effect has been achieved in many fields.

Most of the currently used photodynamic therapy devices (phototherapy for short) use light-emitting diodes (LEDs) to emit laser or non-coordinated light for phototherapy. However, such devices are often desktop machines, and users often can only use them in fixed places, which results in inconvenience due to limitations in use.

Therefore, the object of the present invention is to provide a patch-type phototherapy device that can be attached to human skin and used anywhere.

The excitation light beam emitted by the light-emitting component is converted into a converted light beam through the wavelength conversion patch. The excitation light beam is The wavelength range is different from the wavelength range of the converted light beam; and a controller is electrically connected to the light-emitting component to control the light-emitting component.

In one embodiment of the present invention, a patch-type phototherapy device is provided. The wavelength conversion patch has a skin-friendly layer and a wavelength conversion layer. The skin-friendly layer is made of skin-friendly material, and the wavelength converting layer is made of photoluminescence. Material, the wavelength conversion layer is disposed between the skin-friendly layer and the light-emitting component.

In one embodiment of the present invention, a patch-type phototherapy device is provided. The wavelength conversion patch has a skin-friendly layer and a wavelength conversion layer. The skin-friendly layer is made of skin-friendly material, and the wavelength converting layer is made of photoluminescence. Material, the skin-friendly layer covers the wavelength conversion layer.

In one embodiment of the present invention, a patch-type phototherapy device is provided. The wavelength conversion patch is a mixture of skin-friendly materials and photoluminescent materials.

In one embodiment of the present invention, a patch-type phototherapy device is provided. The light-emitting component has a circuit board and a plurality of light-emitting parts. The plurality of light-emitting parts are arranged on the circuit board. The circuit board is flexible.

In one embodiment of the present invention, a patch-type phototherapy device is provided, further comprising a light diffusion sheet disposed between the light-emitting component and the wavelength conversion patch.

In one embodiment of the present invention, a patch-type phototherapy device is provided, and the light diffusion sheet is a light guide plate.

In one embodiment of the present invention, a patch-type phototherapy device is provided, which further includes a communication module electrically connected to the photography component and the controller for transmitting images obtained by the photography component to the outside.

The technical means adopted by the patch-type phototherapy device of the present invention is a wavelength conversion patch obtained by combining a skin-friendly patch and a photoluminescent material. Due to its small size, the patch-type phototherapy device of the present invention can be attached to the skin and used for skin repair, without having to go to a specific place before use. The patch-type phototherapy device of the present invention can even be used on skin locations covered by clothes, joints or uneven skin, etc. without affecting the user's movement.

Furthermore, because the wavelength conversion patch has photoluminescent materials, it emits light using the principles of fluorescence, quantum dots or phosphorescence. This allows the wavelength range of the excitation beam to be different from the wavelength range of the conversion beam, so that the excitation beam emitted by the light-emitting component can be different from the actual conversion beam that exerts the phototherapy effect, thereby reducing the restrictions on the selection of the light-emitting component.

The embodiments of the present invention will be described below based on FIGS. 1 to 4 . This description is not intended to limit the implementation of the present invention, but is one example of the present invention.

The excitation beam emitted is laser or non-coherent modulation light of visible light, infrared light and/or ultraviolet light. The circuit board 21 is flexible to adapt to the curvature of the human body surface to which the patch-type phototherapy device 100 is attached.

The wavelength conversion patch 1 emits light using the principle of fluorescence, quantum dots or phosphorescence through the photoluminescence material. The excitation beam emitted by the light-emitting component 2 is converted into a converted light beam by passing through the wavelength conversion patch 1 . The wavelength range of the excitation beam is different from the wavelength range of the conversion beam, so that the excitation beam emitted by the light-emitting component can be different from the actual conversion beam that exerts the phototherapy effect, thereby reducing the restrictions on the selection of the light-emitting component.

Different wavelength ranges of the converted light beam will correspond to different curative effects. For example: red light has good penetrating ability, which helps activate blood circulation, relieve pain, and accelerate wound healing; green light helps slow down skin sensitivity symptoms and relieve fatigue; blue light Helps treat acne, prevent wound infections, sterilize, and inhibit oil secretion; infrared light can stimulate muscle repair and relieve joint pain. The material of the wavelength conversion patch 1 is selected based on the wavelength range of the excitation beam emitted by the light-emitting component 2 and the required wavelength range of the converted beam.
