ultrasonic debridement in chronic wounds

When patients suffer from chronic wounds, there is often bacterial infection or necrotic tissue. Low-frequency ultrasonic debridement is a therapy that uses sound waves to remove and separate bacteria and dead tissue from wounds. In the application of low-frequency ultrasonic debridement, the use of sound waves below 60kHz can remove bacteria and necrotic tissue from infected or hypoxic tissue areas to promote wound healing.

What is low-frequency ultrasound debridement?

Low-frequency ultrasonic debridement is a therapy that removes and separates bacteria and necrotic tissue from wounds by using low-frequency (below 60kHz) sound waves. It is a non-invasive treatment that stimulates and accelerates the tissue's self-repair by delivering sound waves into damaged tissue.

Specifically, low-frequency ultrasonic debridement transmits sound waves through a probe to the patient's wound site, and these sound waves can produce a "microkinetic" effect that separates and removes bacteria and necrotic tissue. In addition, low-frequency ultrasonic debridement can also stimulate the metabolism of healthy cells, promote blood circulation, and provide sufficient oxygen and nutrients to the wound, thus speeding up the healing process of the wound.

Low-frequency ultrasound debridement is a safe, non-toxic treatment that causes no pain or discomfort to the patient. It is an ideal treatment, especially for chronic wounds, skin ulcers, pressure sores, and other difficult-to-heal wound lesions.

The role of low-frequency ultrasonic debridement in chronic wounds is mainly manifested in the following aspects:

1. Remove necrotic tissue and bacteria

The use of low-frequency ultrasonic debridement can stimulate the separation of bacteria and necrotic tissue harbored in the infected tissue area and be cleared. Removal of these harmful substances is critical to the recovery and healing process of wounds. Because they can inhibit the growth and recovery of healthy tissue, which in turn hinders wound healing.

2. Promote metabolism

Low-frequency ultrasonic debridement can produce an effect called "microkinetics", which can stimulate the metabolism of surrounding cells, increase tissue vitality, and accelerate the growth and recovery of healthy cells. These effects aid wound healing because they provide cells with sufficient nutrients and oxygen to promote the growth of healthy tissue.

3. Reduce recovery time

Wound healing often takes a long time, and low-frequency ultrasonic debridement can help shorten recovery time. The use of low-frequency ultrasound can stimulate blood circulation and increase tissue blood supply, which will facilitate the delivery of red blood cells and oxygen, thereby helping tissue recovery and ultimately wound healing.

In general, low-frequency ultrasonic debridement is very effective for the rehabilitation of chronic wounds. It removes harmful substances, stimulates the metabolism of healthy cells, increases blood supply to tissues, and helps heal wounds. The wound after debridement can be matched with Silicone Foam Dressing, which can protect the wound surface well, and at the same time provide a moist healing environment, absorb a large amount of exudate, and is very convenient to use. Therefore, low-frequency ultrasonic debridement is a kind of Reliable treatment, especially for those with chronic wounds who need a quick recovery.
