Cold therapy units, frequently utilized following surgical procedures, deliver localized cooling to injured tissues. These devices typically consist of a reservoir for ice and water, a pump to circulate chilled water, and an adjustable pad or cuff applied to the affected area. For example, a patient recovering from knee surgery might utilize such a device with a cuff specifically designed for the knee joint.
Controlled cooling effectively reduces pain and inflammation by constricting blood vessels and numbing nerve endings. This, in turn, can minimize swelling and tissue damage, promoting faster healing and improved patient comfort during recovery. Historically, basic ice packs and elevation were the primary methods for managing post-operative swelling and pain. Advances in technology have led to more sophisticated systems offering precise temperature control and targeted application, enhancing therapeutic benefits.
