AI Technical Summary

Technical Problem

Existing negative pressure therapy equipment cannot dynamically adjust the pressure, leading to damage to newly formed tissue. Phototherapy equipment cannot adapt to changes in the wound in real time. Traditional systems cannot achieve individualized and precise treatment and have risks of improper management of exudate and infection, especially with poor adaptability to irregular wounds.

Method used

An adaptive bio-interface composed of a multi-layer composite dressing matrix and a shape memory alloy skeleton is used to integrate a multi-spectral photothermal coupling therapy module and a gradient sterilization exudate management system. Combined with an intelligent control system based on a differential pressure sensor array and a multi-modal data fusion algorithm, it can achieve dynamic negative pressure adjustment and real-time phototherapy to adapt to changes in the wound surface.

Benefits of technology

It enables precise, adaptive, and closed-loop management of burn wounds, reducing the risk of infection, improving treatment efficiency, reducing operational burden, and adapting to wounds of different sizes and shapes.

Abstract

This invention relates to an intelligent dynamic negative pressure and phototherapy integrated burn wound treatment device, belonging to the field of medical device technology. It comprises a contact layer, a conductive layer, and a honeycomb support layer. The contact layer drains exudate, the conductive layer integrates a fiber optic network and an adaptive deformation mechanism, and the honeycomb support layer connects an intelligent negative pressure chamber and a gradient sterilization system. The negative pressure chamber dynamically adjusts pressure through corrugated airbags and diamond-shaped telescopic units, while the photothermal component irradiates the wound at different times and maintains a constant temperature. The sterilization system uses ultraviolet pulses and multi-stage filters to purify exudate. The intelligent control module optimizes treatment parameters in real time through a multimodal sensor network, achieving a closed-loop synergy of negative pressure, phototherapy, and sterilization. This device overcomes the limitations of traditional treatments through its integrated design, significantly improving wound repair quality and anti-infection capabilities. Simultaneously, its modular expansion and non-invasive monitoring functions reduce the burden on medical staff, providing an efficient and safe intelligent solution for burn management.
