Low frequency non-contact ultrasound therapy: Low-frequency non-contact ultrasound therapy (LF-UCWT) in wound care is a therapeutic approach that uses low-frequency sound waves to stimulate wound healing. Unlike traditional ultrasound, this method is non-contact, meaning the ultrasound device doesn’t directly touch the wound, reducing the risk of further trauma or contamination. The ultrasound waves are delivered through a mist or saline solution to the wound bed, helping to accelerate healing by stimulating tissue repair, reducing bacteria, and improving circulation.
Therapeutic Effects:
- Debridement: Helps remove necrotic tissue by breaking it down gently, which supports wound bed preparation.
- Antibacterial: The mechanical action of the ultrasound disrupts bacterial biofilms, reducing infection risk.
- Increased Blood Flow: The therapy improves microcirculation in the wound, promoting the delivery of oxygen and nutrients to the healing tissue.
- Cell Stimulation: The sound waves stimulate cellular activities, such as collagen production, that are essential for wound repair.
LF-UCWT is particularly useful in wounds that are resistant to other forms of treatment, offering a safe and painless option for enhancing wound healing. It is typically used as part of a comprehensive wound care strategy, alongside debridement, dressings, and other interventions.
