Negative Pressure Wound Therapy (NPWT) is a medical technique to promote the healing of wounds by applying vacuum to a sealed wound dressing. It is used to treat chronic, acute and post-operative wounds. This vacuum helps remove excess fluid while stimulating tissue growth leading to faster wound closure.
Key Pump Functions and Requirements
NPWT devices are designed for patient comfort and mobility. This requires compact, lightweight and efficient pump solutions. The pump must be leak-tight to maintain the required vacuum level, operate efficiently to extend battery lifetime and sport a low sound level for patient comfort.
The Thomas Solution
Thomas gas diaphragm pumps are engineered to provide the stable flow and working point required for Negative Pressure Wound Therapy. The pumps are designed to ensure low pulsation, leak-tightness, and a superior size-to-performance ratio. Quality DC motors allow for optimized speed control to enhance pump efficiency and lifetime.
