Smart Compression Therapy Devices for Treatment of Venous Leg Ulcers: A Review

Abstract

Venous leg ulcers can have significant social and economic impacts, and are generally treated by applying compression to the lower limb, which aids in promoting blood return to the heart. Compression therapies commonly involve the use of passive bandages that suffer from issues associated with incorrect application, and although automated solutions have begun to appear; these are often bulky and hinder mobility. Emerging microtechnologies and new materials enable the development of "smart" compression therapy devices, which are defined as systems that use miniaturized and lightweight actuators and electronics to control the applied pressure. This paper reviews the state of the art in smart compression therapy research. A total of seventeen different devices has been identified, categorized as using one of three actuation mechanisms: pneumatic compression, motor-driven mechanisms, and smart materials (including shape memory alloys, shape memory polymers, and electroactive polymers). The field is still in its relative infancy and further refinements are required to create mass manufacturable compression dressing systems that meet medical, ergonomic, and economic standards. The use of miniaturized actuators has immense potential for the development of smart compression dressings, which will ultimately lead to higher compliance, increased patient comfort, enhanced mobility, and better treatment outcomes.

Prevention strategies for the recurrence of venous leg ulcers: A scoping review

“…Pressure level should also be continuously monitored. Applying the correct pressure is significant for effective treatment, which helps to improve the quality of patients' life at all stages 33 . Thus, it is necessary to measure the compression device based on the patients' situation and circulation to maintain appropriate pressure.…”

Acquisition, status and transfer of knowledge in compression therapy

“…Das Wissen der Versorger in der phlebologischen Kompressionstherapie ist seit Jahren ungenügend, aktuelles Material ist häufig nicht bekannt, und eine sach- und fachgerechte Umsetzung erfolgt selten [ 7 – 12 ]. Bisherige Studien fokussieren oft auf die Verbesserung der Ergebnisse einer phlebologischen Kompressionstherapie durch Änderung und Anpassung der Materialien [ 13 – 15 ]. Ein nicht einsetzender Therapieerfolg liegt aber nicht nur an den verwendeten Versorgungsoptionen, sondern auch daran, wie diese von den Anwendern eingesetzt werden [ 16 ].…”

Novel modalities of delivering herbal medicines for wound healing: A review

“…There is some parameter involved in sensing technologies for wound management like; pH of the wound site, temperature, moisture in the dressing, bandage pressure, and odor of the wound (Figure 3). 116 …”
