Negative Pressure Wound Therapy Devices

Negative Pressure Wound Therapy

For the last two decades or so, medical advances have changed the way we think about healing. Things that used to take weeks or months can now be achieved in a few days. Chronic illnesses that were untreatable are now easily managed. It’s no surprise that these advances have paved the way for major developments in wound care, and thus the introduction of negative pressure wound therapy.

While it may sound like something off the Star Trek ship, the proven method of negative pressure wound therapy has been a godsend to people with chronic wounds or those with severe injuries. The process works by first applying wound dressings to the area. The dressing is made of special and specific materials that absorb excess fluids. A drainage tube is connected to the dressing at one end and a device at the other. This device acts as a vacuum, constantly clearing the wound fluids from the area. KCI wound VAC units are an example of these devices that apply either constant or intermittent pressure to the area to increase blood flow and remove fluid buildup. How often the device drains will depend on your needs, and also your tolerance level for the therapy. These devices have seen radical and exciting changes in the last 2 decades and are even now covered by insurance in some cases.

How well this treatment will work from you depends on many factors affecting wound healing. The size, severity and shape of the wound will determine how effective negative pressure wound therapy will work for you. Diabetic ulcers have shown great promise for use of the treatment.

There are many stages of wound healing for most people, but for people with chronic wounds, they can seem stuck in limbo with gashes or sores that refuse to heal whether from illness or other medical condition. These are also good candidates for negative pressure wound therapy.

Your doctor will determine if this method is right for you based on your condition and other factors. Thankfully, there are few side effects resulting from this treatment and your physician will decide if you can benefit from this treatment.
