Negative Pressure Wound Therapy Devices: Mechanical

Mechanically powered negative pressure wound therapy (NPWT) systems are non-powered devices indicated for the application of suction (negative pressure) to promote wound healing and for the removal of fluids such as wound exudate, irrigation fluids, bodily fluids or infectious materials. Mechanical NPWT devices may be indicated for use on chronic, acute, traumatic, subacute, and dehisced wounds, diabetic ulcers, pressure ulcers, skin flaps and grafts. Mechanical NPWT devices are lightweight in design for portable patient use, using spring and coil mechanisms to generate subatomospheric pressure to stimulate the wound area.

Overview

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.

Mechanical negative pressure wound therapy systems are powered by a spring mechanism which is used to create a vacuum to provide suction to the wound bed.

Features

Mechanical negative pressure wound therapy devices feature the following general performance properties and attributes:
• Improves cellular migration and promotes granulation tissue formation
• Ideal for use in home settings
• Small, lightweight and portable
• Silent operation
• Single-use, disposable product

Indications

Mechanical 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, surgically closed incisions, partial-thickness burns, skin flaps and grafts.

Contraindications

Mechanical 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.

Warnings

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. Always refer to manufacturer Instructions for Use.
