The Concept of Wound Bed Preparation and TIME
▪ Wound bed preparation (WBP)
is an important component of
the TIME global wound care framework
▪ The WBP concept includes tissue
management (debridement) and
biofilm prevention and removal
strategies
▪ Proper moisture balance and
wound cleansing are associated
aspects of WBP
WBP is a well established concept
TIME framework is a practical tool to assist practitioners when assessing &
managing patients

HOW DOES IT WORK?
UAW Product Presentation
• Low frequency ultrasound (25kHz)
• Ultrasonic vibrations Cavitation Bubbles Debridement
Microstreaming
Stimulates release of growth factors,
fibroblast migration & epithelization
Healthy tissue not affected due
to its higher elastin content

Clinical Effects
1. Debridement & selective debridement
• Cavitation & microstreaming create a shearing force which is greater
than strength of necrotic tissue, liquefies & breaks off the non viable
tissue
• Healthy tissue is more elastic
2. Wound healing stimulatory effects/maintain wound in healing mode
• Stimulate the release of growth factors, fibroblast migration &
proliferation and encourage epithelialization on periwound
(Sussman & Dyson, 2007)3. Bactericidal
• Bacteria and biofilm is dislodged by cavitation & microstreaming effect
• Shockwaves disrupt the cell membrane, encourage nitrous oxide
production (Altland et al, 2004)

Key Benefits Hospital Patient
1. Time and cost saving:• Applicable by nursing staff √ √
• Local anesthetics sufficient √ √
• No extensive operative settings √
• Access to difficult to reach areas √
• Completely autoclavable √
• As effective as sharp debridement √
2. Less pain and traumatic √
3. Faster & better outcome (20-30 second per cm²) √ √
4. Can be repeated √

IMPORTANT !
Cavitation only emerge in liquids.
A wet or moistly operation field is important.
Without liquid strong THERMAL effects are generated!
Liquid is needed to:
•transmit the energy
•cool down the working area
•transport the fragmented tissue and cells
