Description
Technical Field
The present disclosure relates generally to the technical field of medical devices, and more particularly to a flexible phototherapy device and bandage for wound treatment.
Background
Phototherapy treatments are known to be effective in assisting healing of wound sites 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 and skin regeneration of damaged skin tissue.
However, phototherapy alone 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 increased levels of treatment, such as, for example, additional application of topical medications or special dressings or wound covers. Monitoring of the healing process and altering the treatment is also difficult.
Existing phototherapy systems generally use light sources such as LEDs, fluorescent lamps, halogen lamps, and ultraviolet lamps. These systems are generally not directly adaptable 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 may be attached to the skin of a person or animal and that may be wrapped around a body part of a person or animal. However, the flexible light patch of the phototherapy device can achieve good phototherapy effect only when attached to a relatively flat position of the skin of a person or animal; aiming at the positions of joints and the like, the flexible optical 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 LEDs in the cavity of the light transmission element is fixed, and only a plurality of uniformly distributed light irradiation areas can be formed in the wound area, so that the wound is in a non-uniform heated state as a whole, and the wound healing is not good. Therefore, we propose a flexible phototherapy device and bandage for wound treatment, which are used for solving the problems of poor phototherapy effect caused by independent radiation of the light irradiation area of the phototherapy device.

In this embodiment, on the basis of embodiment 5, a second light adjusting component is designed between the flexible base layer 1 and the flexible connection portion 17, and is located in the gap to enlarge the area of the light radiation area;
further, the second illumination adjustment assembly includes:
two electromagnets 11 are arranged near the center of the flexible base layer 1, and the electromagnets 11 are connected with a power supply circuit to control the existence of magnetism of the electromagnets 11;
the supporting block 12 is arranged between the two electromagnets 11, plays a role in supporting and blocking the two electromagnets 11, and prevents the two electromagnets 11 from generating interaction force when magnetism is generated simultaneously by the two electromagnets 11, and the two electromagnets repel or attract each other, so that the electromagnets 11 and the corresponding adsorption blocks 13 can not be well adsorbed together, and the effect of adjusting the light radiation area is affected;
here, the supporting block 12 is made of flexible materials, and the electromagnet 11 and the supporting block 12 are arranged in the flexible base layer 1 along with the shape, so that the supporting block 12 can generate corresponding deformation along with the change of the preset angle of the flexible base layer 1, and the device is enabled to be more attached to the skin;
the two adsorption blocks 13 are arranged on the flexible connecting part 17 and are arranged in one-to-one correspondence with the two electromagnets 11 and are used for being matched with the electromagnets 11 to enlarge the light radiation area; when the two electromagnets 11 are in the electrified state, the electromagnets 11 have magnetism and can absorb the absorption block 13 similar to the electromagnets, so that the device is better attached to the joint part;
as shown in fig. 9, the power supply circuit is turned on, so that the electromagnet 11 generates magnetism to absorb the corresponding absorption block 13, the absorption block 13 approaches to the flexible substrate 1, drives the flexible connection portion 17 to move towards the center position thereof, and drives the second flexible light reflection region 16 to move towards the center position of the flexible connection portion 17, so as to enlarge the emergent angle of the light emitted by the light source 4, and finally form a light radiation region to be smaller, so that a wound part with a larger area is suitable.
Further, the pressing part 18 is arranged on the surface of the flexible base layer 1 away from the gap, so as to facilitate pushing the electromagnet 11 to be close to the adsorption block 13;
the light diffusion cover 14 is covered on the light source 4, and has a refraction effect on the light emitted by the light source 4, so that the light is diffused to form a larger radiation area.
Example 8
Combining example 6 with example 7, such that the light radiating area of the device is adjustable to accommodate different sizes of wound area;
as shown in fig. 10, when the first light adjusting assembly and the second light adjusting assembly are adjusted at the same time, the maximum light radiation area can be obtained; the first illumination adjusting component and/or the second illumination adjusting component can be adjusted according to the actual wound area, so that a good treatment effect is achieved.
Example 9
A bandage, comprising: a flexible phototherapy device for wound treatment according to any of embodiments 1 to 8, wherein the bandage is wound around the wound area, such that the flexible phototherapy device can stably treat the wound.
