Portable treatment device of electric field coupled with negative pressure for promotion of wound healing

Abstract

The invention discloses a portable treatment device of electric field coupled with negative pressure for promotion of wound healing. The device comprises a main part, a sandwich-shaped foam dressing, a first biocompatible transparent membrane, anode and cathode patches and a sucker-type drainage tube containing wires; the main part provides negative pressure and direct-current electric field; the sandwich-shaped foam dressing is a negative pressure drainage material for a wound, and meanwhile is used for providing electric field for the wound; the first biocompatible transparent membrane is used for covering the dressing and normal skin around the wound, so that the wound is sealed; the anode and cathode patches are used for being connected with a power supply, and are attached to anode and cathode carbon fiber foam dressings respectively; the sucker-type drainage tube containing the wires has dual effects of drainage and electric conduction, one end of the drainage tube is connected with the foam dressing and the anode and cathode patches, and the other end of the drainage tube is connected with the main part. According to the portable treatment device, negative pressure and direct-current electric field can be applied on the wound synchronously, organic synergy of sealed negative pressure drainage and direct-current electric field technologies for promotion of wound healing is achieved, healing of various acute and chronic wounds is obviously accelerated.

Description

technical field [0001] The invention belongs to electric field coupling negative pressure technology, and specifically refers to a portable electric field coupling negative pressure treatment device for promoting wound healing. Background technique [0002] Acute skin and soft tissue injuries are the main type of trauma. Due to factors such as complex injuries, untimely treatment, and negligent nursing care, skin wound infections and blood supply disorders are prone to occur, resulting in prolonged wound healing. At the same time, with the aging population in my country, the incidence of skin ulcers caused by various chronic diseases such as diabetes, vascular diseases, pressure sores, etc. is increasing year by year. , often form chronic wounds, resulting in difficult wound healing, seriously affecting the patient's appearance and functional recovery. [0003] A certain intensity of continuous or intermittent wound sealing negative pressure drainage can avoid wound infecti...

Problems solved by technology

However, the role of wound electric field in promoting wound healing depends on a good microenvironment of the wound; at the same time, there are many inconveniences in the operation level of applying an exogenous electric field on the wound, especially how to fix the positive electrode material on the normal skin of the wound margin and the negative electrode material on the wound. There are technical obstacles in the center of the wound, how to avoid the displacement of positive and negative materials during the continuous application of electric field, so the technology of using external electric field to promote wound healing has not been effectively clinically transformed and applied.
