The Shoulder-Float Adjustable Axillary Support Device helps anesthesia staff position and reposition a patient optimally during surgical procedures performed in the lateral decubitus position. Invented by two anesthesiologists, the device can be adjusted throughout a procedure to maintain an even weight distribution, without having to manually lift or move the patient. It is easy to use. Health care professionals can simply slide the uninflated Shoulder-Float Device under the patient’s axilla and inflate enough to lift the shoulder off the table. It helps relieve a patient’s shoulder discomfort and reduces instances of staff and patient injuries due to lifting. It replaces the foam, beanbag or gel axillary rolls often used. It can be used with bariatric procedures.
