Anastomotic leak testing apparatus

Abstract

Anastomotic leak tester for testing for leaks in a gastrointestinal anastomosis in a patient including an air introduction system adapted to be inserted into the patient's gastrointestinal tract through a natural body orifice of the patient and enabling air flow therethrough into the gastrointestinal tract and a regulating mechanism arranged in connection with the air introduction system for regulating air pressure in the patient's gastrointestinal tract. The regulating mechanism may include a pressure relief valve having an inlet communicating with an interior space of the air introduction system communicating with the patient's gastrointestinal tract and which allows air to be released from the patient's gastrointestinal tract when air pressure in the patient's gastrointestinal tract exceeds a predetermined pressure. The pressure relief valve may generate an audible indication when air pressure in the patient's gastrointestinal tract exceeds the predetermined pressure.
