Description
Technical Field
The present disclosure relates generally to the field of medical devices, and more particularly to a flexible phototherapy device and a bandage for wound treatment.
Background
Phototherapy treatment is known to be effective in assisting the healing of the wound site and surrounding skin and tissue. Phototherapy can affect human skin because light can be absorbed, reflected, scattered in human skin. In addition, light from phototherapy can promote biochemical reactions in skin cells, enhance collagen production, and accelerate repair of damaged skin tissue and skin regeneration.
Phototherapy alone, however, is generally not effective for severe or complex skin wounds involving deep punctures or tears, surgical sites, skin burns, and the like. Often, these wounds require an increased level of treatment, such as, for example, the additional application of topical medications or specialized dressings or wound coverings. Monitoring of the healing process and altering the treatment is also difficult.
Existing phototherapy systems typically use light sources such as LEDs, fluorescent lamps, halogen lamps, and ultraviolet lamps. These systems are generally not directly applicable to the wound site because the light source may generate too much heat and may also be in a rigid structure that cannot be effectively or comfortably attached to the skin. As disclosed in patent CN103037938B, the flexible phototherapy device may be implemented in a plaster or bandage that can be attached to the skin of a person or animal and/or that can be wrapped around a body part of a person or animal. The flexible light patch of the phototherapy device can achieve good phototherapy effect only when being attached to a relatively flat position of the skin of a human or an animal; aiming at the positions of joints and the like, the flexible light patch cannot be tightly attached to the skin, and the phototherapy effect is poor; in addition, the treatment area formed by the light emitted by the LED in the light transmission element cavity is fixed, and only a plurality of light irradiation areas which are uniformly distributed can be formed in the wound area, so that the whole wound is in a state of being heated unevenly, and the wound healing is not favorable. Therefore, a flexible phototherapy device and a bandage for wound treatment are proposed to solve the problem of poor phototherapy effect due to independent irradiation of the light irradiation region of the phototherapy device.

as shown in fig. 9, the power supply circuit is turned on, so that the electromagnet 11 generates magnetism to adsorb the corresponding adsorption block 13, the adsorption block 13 approaches the flexible base layer 1, drives the flexible connection portion 17 to move toward the center position thereof, and drives the second flexible light reflection area 16 to move toward the center position of the flexible connection portion 17, so as to enlarge the exit angle of the light emitted by the light source 4, so that the finally formed light radiation area is reduced, and the wound part with a larger area is suitable for.
Furthermore, the pressing part 18 is arranged on the surface of the flexible base layer 1 far away from the gap, so that the electromagnet 11 can be conveniently pushed to be close to the adsorption block 13;
and the light diffusion cover 14 is covered on the light source 4 and plays a role in refracting the light emitted by the light source 4, so that the light is diffused to form a larger radiation area.
Example 8
The combination of the embodiment 6 and the embodiment 7 enables the light radiation area of the device to be adjustable so as to be suitable for wound areas with different sizes;
as shown in fig. 10, when the first illumination adjusting assembly and the second illumination adjusting assembly are adjusted simultaneously, the maximum light irradiation area can be obtained; the first illumination adjusting assembly and/or the second illumination adjusting assembly can be adjusted according to the actual wound area, and a good treatment effect is achieved.
