What is Negative Pressure Wound Therapy (NPWT)? 

Negative Pressure Wound Therapy (NPWT) is an advanced wound care technique that utilizes subatmospheric pressure to promote healing. This innovative approach involves applying controlled, localized negative pressure to the wound bed, which offers several benefits for wound management and recovery. 

How NPWT Works 

NPWT employs a specialized dressing connected to a vacuum pump that creates negative pressure within the wound environment. This subatmospheric pressure helps to: 

• Remove excess fluid and exudate from the wound 
• Reduce edema and improve blood flow 
• Stimulate the formation of granulation tissue 
• Decrease bacterial colonization 

Benefits of NPWT 

1. NPWT’s ability to remove debris, manage exudate, and promote a moist wound environment makes it a valuable tool in modern wound care. Healthcare professionals often turn to NPWT when conventional wound treatments prove insufficient, as it can significantly improve healing time. 

By leveraging negative pressure, NPWT accelerates the healing process and improves overall wound outcomes. This therapy is particularly effective for: 

• Chronic, non-healing wounds 
• Acute wounds 
• Post-operative incisions 
• Diabetic foot ulcers 
• Skin Graft 
• Full thickness burns 
• Trauma wounds 

2. Enhanced Blood Flow and Nutrient Delivery 

NPWT promotes increased blood flow to the wound area, which is crucial for effective healing. This enhanced circulation delivers essential nutrients and oxygen to the wound site, fostering an optimal environment for tissue repair and regeneration. The improved blood flow also helps remove waste products and debris, further supporting the healing process. 

3. Wound Cleanliness and Infection Prevention 

One of the primary benefits of NPWT is its ability to maintain a clean wound environment. By creating a sealed system, NPWT significantly reduces the risk of external contamination. The continuous removal of excess fluid and debris helps keep the wound bed clean, minimizing the possibility of infection. This cleaner environment not only supports faster healing but also reduces the need for frequent dressing changes, enhancing patient comfort. 

4. Accelerated Healing Process 

NPWT's unique approach to wound management stimulates the formation of granulation tissue, a crucial step in wound healing. By applying controlled negative pressure, NPWT encourages the growth of new blood vessels and promotes the contraction of wound edges, ultimately speeding up the healing process for both acute and chronic wounds. 

Variable Pressure Technology for Enhanced Therapy 

There are different types of Pressure Therapy available.  

Continuous Pressure Therapy is the most common setting used with only one pressure set throughout the therapy duration. 

Intermittent Pressure Therapy setting offers an alternate high and low pressure. 

DeRoyal's Negative Pressure Wound Therapy (NPWT) devices stand out in the field of wound care with their innovative variable pressure technology. Variable Pressure Therapy (VPT) is a patented feature of DeRoyal Prospera II NPWT machine. Unlike Intermittent Pressure Therapy, Prospera® VPT® technology is engineered to deliver a more comfortable variable pressure therapy through gradual increase and decrease of pressure which avoids high and low pressure spikes. By alternating pressure levels, the device promotes better blood circulation and stimulates tissue regeneration, leading to faster wound closure and reduced healing times.  

 

 

 

Rigorous Testing for Optimal Performance 

DeRoyal's commitment to excellence is evident in their comprehensive testing process. The NPWT devices undergo thorough evaluations involving lay users, caregivers, and clinicians to ensure optimal functionality and intended outcomes. This multi-faceted approach to testing helps identify and address potential issues before the device reaches patients, resulting in a more reliable and effective treatment option. 

Improved Patient Outcomes 

The combination of variable pressure technology and extensive testing translates into tangible benefits for patients. Users of DeRoyal's NPWT devices often experience: 

• Faster wound healing 
• Reduced risk of infection 
• Improved comfort during treatment 
• Greater mobility and independence 

By prioritizing both technological innovation and user-centric design, DeRoyal's NPWT devices are setting new standards in wound care and consistently delivering improved patient outcomes.
