An electric field coupled negative pressure portable treatment device for promoting wound healing

Abstract

The invention discloses an electric field coupled negative pressure portable treatment device for promoting wound healing, which includes a host, a "sandwich-like" foam dressing, a biocompatible transparent film, positive and negative patches, and a suction cup drainage with wires tube; the host provides negative pressure and DC electric field; the "sandwich" foam dressing is not only a negative pressure drainage material for the wound, but also used to provide an electric field for the wound; a biocompatible transparent film is used to cover the dressing and the normal skin around the wound to seal it The wound surface; the positive and negative patches are used to connect to the power supply, and are pasted on the positive and negative carbon fiber foam dressings respectively; the suction cup drainage tube containing wires has dual functions of drainage and conduction, one end of which is connected to the foam dressing and the positive and negative patches, and the other One end is connected to the host. The invention can simultaneously apply negative pressure and direct current electric field to the wound surface, realize the organic synergy of closed negative pressure drainage and direct current electric field technology to promote wound surface healing, and significantly accelerate the healing of various acute and chronic wound surfaces.

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...

AI Technical Summary

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.
