Summary
This study demonstrates a low-cost method for negative pressure wound therapy using readily available materials. This approach offers comparable results to expensive commercial systems, making advanced wound care more accessible.
Area of Science:
- Biomedical Engineering
- Wound Care Innovation
Background:
- The KCI Wound VAC system, a standard for negative-pressure therapy, presents cost barriers for uninsured patients.
- High cost limits access to effective wound treatment modalities.
Purpose of the Study:
- To assess the feasibility of creating an affordable negative pressure wound therapy (NPWT) system.
- To develop a cost-effective alternative to commercial NPWT devices.
Main Methods:
- Assembly of a novel NPWT dressing using off-the-shelf components: adhesive drape, Jackson-Pratt drain, and foam sponges.
- Connection of the dressing to standard wall suction to achieve therapeutic negative pressure (-75 to -100 mm Hg).
- Estimated component cost under $60 USD.
Main Results:
- Successful application in over 40 patient cases.
- Clinical outcomes appeared comparable to the commercial KCI Wound VAC system.
- No instances of bleeding or other complications were reported.
Conclusions:
- Off-the-shelf components can be safely and effectively utilized for NPWT.
- This low-cost NPWT system provides a viable alternative for wound and skin graft treatment.
- Increased accessibility to NPWT for patients facing financial constraints.
