Brief Description:


Bandages have been used since ancient times to cover wounds in order to prevent infection. However, current bandages do not optimally hinder infections or fully leverage the wound healing capacity of our bodies. Particularly for infectious wounds, existing bandage designs do not meet clinical needs for contamination reduction and healing promotion. Indeed, approximately 1 of every 25 hospitalized patients in the United States contracts a health care-associated infection. A novel bandage design that optimizes healing, prevents wound infection, and minimizes communication of infectious diseases to others would provide a simple solution to an unmet medical need.


An innovative bandage has been created which features an air-permeable, liquid-impermeable material, a wound isolation capsule, and a transparent window. The air-permeable, liquid-impermeable material allows airflow into the wound site to increase the healing process, while preventing water and other contaminates from entering or leaving the wound area. The wound isolation capsule suspends the bandage device above the wound site, protects a majority of the bandage from contamination by the wound itself, and prevents physical disruption of the wound during the healing process. The transparent window allows visual inspection of the wound without removing the bandage from the patient. All of these features optimize the wound healing process, provide convenient monitoring of the wound, and minimize exposing individuals to contaminated materials.


Applications of this technology include using a bandage to isolate inoculation sites, lesions, burns, warts, infectious lesions, skin cancers, suture sites, ulcers, or other suitable areas of a patient. This technology is suitable for clinicians and anyone involved in wound care.
