Ultrasound-Based Non-Invasive Device Developed by Lithuanian Scientists to Boost Blood Circulation

Lithuanian scientists have developed an innovative non-invasive ultrasound device aimed at improving blood circulation in the lower limbs, a solution particularly beneficial for elderly individuals and patients with diabetes-related complications like diabetic foot. This device, a collaborative effort between researchers from Kaunas University of Technology (KTU) and the Lithuanian University of Health Sciences (LSMU), uses piezoelectric elements to emit ultrasound waves that stimulate blood flow. By increasing vascular tone, the device helps address issues stemming from poor circulation without the need for invasive procedures. Diabetic foot, a condition often leading to severe complications such as foot ulcers and amputation, is one of the most challenging complications of diabetes. Due to progressive neuropathy and impaired tissue circulation, these patients often develop severe foot conditions, which traditional medication can’t effectively treat. The device’s ultrasound waves not only enhance circulation but also affect nerve structures, potentially aiding in the management of diabetic neuropathy. Designed for safe, non-contact use, the device operates at low-frequency ultrasound, minimizing adverse effects while maximizing therapeutic impact. It has received both Lithuanian and European patents and could potentially be used in a wide range of medical settings, including rehabilitation hospitals and nursing facilities. The portable nature and individualized software modifications make it ideal for patients with diabetes and chronic vascular issues. Looking ahead, this technology could also facilitate precise drug delivery, targeting affected areas without widespread side effects. KTU senior researcher Dr. Algimantas Bubulis and LSMU professor Vincentas Veikutis believe this advancement represents a promising breakthrough in vascular health, offering a novel, accessible solution to a widespread health issue.
