An expandable surgical chamber for use in conditions of weightlessness.

An expandable surgical chamber of transparent polyvinyl has been designed to provide a sterile environment for minor surgical procedures performed in conditions of weightlessness. Contamination of the cabin with blood and other debris is prevented while performing surgery. The patient's extremity is inserted through a cuff into the surgical chamber. The cuff may be inflated for rapid hemostasis. All instruments and suture material are stored within the chamber.
