Tubing is connected through an opening in the film drape to a canister on the side of a vacuum pump. [10] This turns an open wound into a controlled, closed wound with an airtight seal while removing excess fluid from the wound bed to enhance circulation and remove wound fluids. [11] This creates a moist healing environment and reduces edema ...
The purpose of a drain is to prevent fluid (blood or other) build-up in a closed ("dead") space, [2] which may cause either disruption of the wound and the healing process or become an infected abscess, with either scenario possibly requiring a formal drainage/repair procedure (and possibly another trip to the operating room).
Kinetic Concepts, Inc., (KCI) is a global corporation that produces medical technology related to wounds and wound healing. KCI produced the first product developed specifically for negative pressure wound therapy. In 2013, the company employed 5,000 people and marketed its products in more than 25 countries. [2]
As serum based fluid moves out of the vessels into the interstitial spaces the resultant soft tissue oedema manifests on the wound surface as exudate. [11] In the chronic wound this exudate contains a surfeit of proteolytic enzymes and other components not seen in acute wounds and these compounds have a corrosive effect on the wound bed and ...
The intermittent vacuum therapy (IVT) is a treatment conducted in case of venous and arterial issues as well as in rehabilitation (after sports injuries [1] and vascular complaints). With the aid of normal and low pressure , it should enable to control venous reflux, enhance lymphatic flow [ 2 ] and improve blood flow in periphery and muscles.
An exudate is a fluid released by an organism through pores or a wound, a process known as exuding or exudation. [1] Exudate is derived from exude 'to ooze' [ 2 ] from Latin exsūdāre 'to (ooze out) sweat' ( ex- 'out' and sūdāre 'to sweat').
A chronic wound is a wound that does not progress through the normal stages of wound healing—haemostasis, inflammation, proliferation, and remodeling—in a predictable and timely manner. Typically, wounds that do not heal within three months are classified as chronic. [ 1 ]
The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10 −2 mbar. With special techniques this can be lowered till 10 −7 mbar.
