Apparatus for giving upper gastrointestinal radiological examination
Abstract
Abstract A POUCH ADAPTED TO HOLD A BARIUM SULFATE SUSPENSION WHICH CAN BE DRUNK FROM THE POUCH THROUGH A FLEXIBLE STRAW THAT EXTENDS FROM THE INTERIOR OF THE POUCH TO OUT THE TOP OF THE POUCH. EXCEPT FOR THE STRAW OPENING, THE POUCH, WHEN IN USE, IS CLOSED. THE POUCH HAS COLLAPSIBLE SIDES AND A STIFF BOTTOM TO PERMIT ALTERNATE USES OF THE POUCH. THE STIFF BOTTOM PERMITS THE POUCH TO STAND UP OR TO BE HELD WITHOUT COMPRESSION OF THE INTERIOR, WHICH COMPRESSION WOULD TEND TO FORCE THE CONTENTS OUT OF THE STRAW. ATLTERNATIVELY, THE COLLAPSIBLE SIDES OF THE POUCH PERMIT THE ADMINISTRATOR OF THE UPPER GASTRONINTESTINAL EXAMINATION TO FORCE THE CONTENTS OF THE POUCH OUT THE STRAW INTO THE MOUTH OF A PATIENT WHO BECAUSE OF AGE OR INCAPACITY MAY BE UNABLE TO DRINK FROM THE STRAW.
