Problems solved by technology

These current biological bandages use primary batteries to generate micro-currents to promote wound healing. The electrical signals generated are very weak, and the zinc and silver particles on the biological bandages are continuously consumed while generating micro-currents, so that the entire device can only be used once. Use; In the scheme of using an external power supply, the patient cannot carry it with him, and it is inconvenient to use. However, in the process of providing a micro-electric field at both ends of the wound in the way of piezoelectricity and frictional electricity generation, it is completely limited by external environmental factors, which are related to respiratory rate, Pressure and friction are closely related

Abstract

The invention discloses a portable electric healing patch and a preparation method thereof. The electric healing patch comprises a base material, and a battery pack, a battery pack positive electrode and a battery pack negative electrode which are arranged on the base material, wherein the battery pack comprises two or more microbatteries which are connected in series or in parallel. The battery pack negative electrode is arranged in the center of a wound or near the center of the wound, and the battery pack positive electrode is arranged on the periphery of the wound, so that a round divergent electric field surrounding the wound from outside to inside is formed, and the round divergent electric field is more beneficial to healing of the wound. Besides, the electric healing patch comprises a plurality of micro batteries and can be designed into a charging type, so that the problems of weak electric signals and unobvious electric treatment promoting effect generally existing in the existing electric healing patch are effectively solved.

Description

technical field [0001] The invention relates to the field of functional materials and devices, in particular to an electric healing paste with a built-in micro water system flexible and integrable micro battery and a preparation method thereof. Background technique [0002] The wound healing process of the skin involves the healing mechanism of cell migration and proliferation caused by endogenous current, which is manifested as a "damage current" generated by the skin wound. These biological processes can be stimulated by appropriate external electrical stimulation for the treatment of chronic wounds and ulcers. Electrical stimulation (ES) therapy has been used to accelerate skin wound healing by applying an external electric field to the wound site to simulate and enhance the effect of the endogenous electric field on the wound. However, its application in clinical operations is often limited by bulky equipment, making it difficult to achieve real-time and convenient trea...
