Creation of a Reproducible, Regulated Negative Pressure System for Wound Treatment – RAM VAC, 2025

Abstract

Objective: To create and demonstrate the effectiveness of a low-cost negative pressure system. This study presents the creation of a RAMVAC system using materials and equipment available at our hospital. Material and method: This medical technology research study utilized a "NEW ASRIK 30" negative aspiration device, a tube system made from nasogastric tubes, and a dressing component
consisting of gauze, dressings, and compresses impregnated with additives. Its efficacy was demonstrated on a model and in a healthy subject. Results: The RAM-VAC demonstrated effectiveness with constant and controlled negative pressure, a leak-free tube system, and dressing components with good additive impregnation. The cost was low compared to modern VACs. Furthermore, both systems exhibited the same mechanism of action. Conclusions: The RAM-VAC proves effective in models and in healthy subjects, tolerating negative pressure well without causing discomfort. Its tube system installation with the dressing component is easy and accessible. Moreover, its low price is a significant advantage over modern VACs. This exploratory study, in collaboration with technological engineering, initiated the creation of products developed by local personnel for necessary equipment that complements comprehensive patient care.
