Electronic band-aid and preparation method thereof

Abstract

The invention belongs to the field of miniature electronic biomedical equipment, and particularly discloses an electronic band-aid, which comprises a flexible substrate layer, a conductive layer and aflexible packaging layer. The conductive layer is arranged between the flexible substrate layer and the flexible packaging layer; the conducting layer is a flexible circuit, a plurality of LED elements capable of emitting blue-violet light are arranged on the flexible circuit, and the flexible circuit is connected with a micro battery and a control switch; an adhesive layer is arranged on the surface of the side, making contact with human skin, of the flexible substrate layer. The flexible substrate layer, the conductive layer and the packaging layer can be bent, folded and stretched to guarantee that the band-aid can be better attached to a wound; the electronic band-aid is small in size and convenient to carry; and after the LED element emits light, wound tissue growth can be promoted to achieve the purpose of accelerating wound healing. The invention further discloses a preparation method of the electronic band-aid, and the preparation method is simple in preparation process and easy to popularize.

Description

technical field [0001] The invention belongs to the field of miniature electronic biomedical equipment, in particular to an electronic band-aid and a preparation method thereof. Background technique [0002] Wound trauma is the most common type of injury in human production activities, and in medical treatment, surgery is also a common way in the medical process. These activities all lead to the occurrence of wounds. Studies have shown that the blue-violet light generated by setting the wavelength of the LED at 380-460nm, the peak value at about 410nm, and the power at about 40mW can significantly improve the body's immunity, thereby improving the healing ability of the wound. Blue-violet light has been widely used in large medical devices, but it is bulky and not easy to carry. The traditional wound healing process is generally through the natural healing of the skin, and severe wounds are healed through drug regulation, but the healing process takes a long time. Conten...
