Patent ID: 11737924

Abstract:
Devices and methods herein remove water from human or animal biological waste fluids using one or more forward osmosis filters. The devices allow for the volume of liquid or semi-liquid waste, including potentially infectious liquid waste, to be filtered to reduce potential exposure of healthcare staff to infectious liquid waste. On a hospital, healthcare staff, or individual patient basis, removing water and concentrating the waste can reduce challenges in management and disposal of the waste. Devices herein use forward osmosis to manage and filter, using one or more suitably sized filter(s), biological fluid exudate from wounds. The devices can be constructed to transport water present in the exudate away from a wound. The wound treatment devices herein not only allow for fluid from wounds to be filtered but also provide structures that can protect wounds from external contaminants, including bacteria and viruses. The wound treatment devices can be incorporated into negative pressure wound therapy systems, if desired.
