The patch helps to heal wounds

Ultrasonic stimulated plasterboard can help wounds heal faster.

According to a team of scientists at Drexel University, Philadelphia, USA, the use of plasterboard helps to reduce the size of sores wounds in 4 weeks. Usually wounds in elderly or paralyzed patients may take several months to heal.

Special patches above weigh about 85 grams and use batteries to emit low frequency ultrasound into the wound. This will stimulate the tissue to attach itself to each other, while stimulating the activity of immune cells that play an important role in healing.

Dr. Peter Lewin, a biomedical engineer at Drexel University and a key researcher of the project, said the study aims to develop a device that can be used on a variety of wounds, without causing side effects.

Scientists tried to test the device in 15 patients 4 times a week and each time used for 15 minutes. As a result, red and pink wounds gradually recovered.

Surprisingly, patients who used the machine for more than 45 minutes each time did not achieve good results. Since then, the scientific community said that the dose when performing ultrasound with plasterboard also plays an important role in helping to recover the wound.

According to Dr. Hector, director of ultrasound programs diagnosed at the National Institute of Biomedical Sciences, the technology is a special and effective ultrasound application for the treatment of chronic wounds in the future. In addition, this technique also helps wounds after recovery surgery more quickly.
