Solution Overview
Problem
Current negative pressure drainage systems cannot monitor the negative pressure at a wound surface in real time, making it difficult for healthcare professionals to assess the healing process effectively and potentially disrupting the normal healing process.
Innovation Solution
A negative pressure drainage system that includes a dressing with a collecting device to gather pressure data wirelessly transmitted to a receiving device, which can process and display this data in real time, allowing for adjustments to the negative pressure environment to maintain optimal healing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-time pressure monitoring is implemented, then the ability to monitor negative pressure at wound surface is improved, but the device complexity increases
Solution Approach 1:
The collecting device is buried within the dressing structure, with the pressure sensor integrated into the dressing layers. This nesting approach allows the monitoring function to be embedded within the existing wound care system without adding external components, thereby improving measurement capability while minimizing increases in overall system complexity.
Solution Approach 2:
The collecting device serves multiple functions: it collects pressure data from the wound surface, wirelessly transmits this data to external devices, and integrates with the existing negative pressure drainage system. By combining these functions into a single multi-functional component, the system achieves real-time monitoring capability without proportionally increasing complexity.
2Loss of information
If frequent dressing changes are performed to assess healing, then the ability to evaluate wound condition is improved, but the disruption to healing process increases
Solution Approach 1:
The system continuously collects pressure data from the wound surface and transmits it to external receiving devices, creating a feedback loop that provides real-time information about wound conditions and negative pressure levels. This allows healthcare providers to monitor healing progress without physically disturbing the wound, eliminating the need for frequent dressing changes while maintaining reliable healing process stability.
Solution Approach 2:
The patent replaces the mechanical assessment method (physical inspection during dressing changes) with an electronic sensing and wireless transmission system. The pressure sensor and wireless communication module substitute for manual visual inspection, allowing continuous monitoring of wound conditions and negative pressure levels without mechanical disruption to the healing process.

AI summary
A negative pressure drainage system is disclosed, including a dressing for being applied to a wound surface of a patient; a collecting device, buried in the dressing for collecting a pressure at the dressing in real time to obtain pressure data; a receiving device, wirelessly connected with the collecting device, where the collecting device wirelessly is configured for transmitting the pressure data to the receiving device. Enabling the negative pressure drainage system to satisfy the above structure is beneficial to collecting the pressure data at the dressing in real time, thereby realizing real-time monitoring of a negative pressure at the wound surface.
