Negative Pressure Wound Therapy Devices: Powered
Negative pressure wound therapy (NPWT) systems are FDA class II devices that consist of a vacuum pump, drainage tubing, and wound dressing set requiring electricity to maintain its use. NPWT applies suction (negative pressure) to promote wound healing and for the removal of fluids such as wound exudate, irrigation fluids, bodily fluids, or infectious materials. NPWT may be indicated for use on chronic, acute, traumatic, subacute, and dehisced wounds; diabetic ulcers; pressure injuries; and skin flaps and grafts.
Negative pressure wound therapy (NPWT) systems are FDA class II devices that consist of a vacuum pump, drainage tubing and wound dressing set. They are designed to provide sub-atmospheric pressure to a wound to promote wound healing and for the removal of fluids such as wound exudate, irrigation fluids, bodily fluids or infectious materials. negative pressure wound therapy devices are powered by either an external power source or a battery which is used to create a vacuum to provide suction to the wound bed.
Powered negative pressure wound therapy devices feature the following general performance properties and attributes:
• Improves cellular migration and promotes granulation tissue formation
• Available for use in clinical and home settings
• Variety of pressure settings for different treatment protocols
• May have alarms to alert patient or caregiver of errors in the system’s operation
Powered negative pressure wound therapy is indicated for removal of excess exudates, infectious material and tissue debris from chronic, acute, traumatic, subacute, and dehisced wounds such as: diabetic neuropathic ulcers, partial- and full-thickness pressure ulcers, venous insufficiency ulcers, partial-thickness burns, skin flaps and grafts.
Powered negative pressure wound therapy is contraindicated in cases where there is malignancy in the wound (except for quality of life reason for terminal patients), untreated osteomyelitis, non-enteric and unexplored fistulas, necrotic tissue with eschar present, exposed vasculature, exposed nerves, exposed anastomatic site, exposed organs, malnourished patients or for pediatric use.
Patients on anticoagulants or with difficult hemostasis should be treated with caution and have to be controlled regularly for bleeding. Remove negative pressure device prior to MRI procedures. Alway refer to manufacturer Instructions for Use.
