Vacuum for wound healing npwt wound npwt therapy

Vacuum for wound healing NPWT dressing:

A wound vacuum system has several parts. A foam or gauze dressing is put directly on the wound. An adhesive film covers and seals the dressing and wound. A drainage tube leads from under the adhesive film and connects to a portable vacuum pump. This pump removes air pressure over the wound. It may does this either constantly. Or it may do it in cycles.

The dressing is changed every 24 to 72 hours. During the therapy, you’ll need to carry the portable pump everywhere you go.

You might need this therapy for a recent traumatic wound. Or you may need it for a chronic wound. This is a wound that is not healing properly over time. This can happen with wounds linked to diabetes. You may need a wound VAC if you’ve had a recent skin graft. And you may need a wound VAC for a large wound. Large wounds can take a longer time to heal.

Machanism action:

A wound vacuum system may help your wound heal more quickly by:

• Draining excess fluid from the wound
• Reducing swelling
• Reducing bacteria in the wound
• Keeping your wound moist and warm
• Helping draw together wound edges
• Increasing blood flow to your wound
• Decreasing redness and swelling (inflammation)

Wound VAC offers some other advantages over other types of wound care. It may decrease your overall discomfort. The dressings usually need changing less often. And they may be easier to keep in place.

Indication:

NPWT dressing is used if you have a burn, pressure ulcer, diabetic ulcer, chronic (long-lasting) wound, or injury. These dressings are indicated for use with negative pressure wound therapy devices for the 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. This therapy can help your wound heal faster and with fewer infections.
