insufflator

Full Definition

An insufflator is a specialized medical device that regulates the delivery of carbon dioxide gas into the peritoneal cavity during laparoscopic surgery. The device monitors and maintains the desired intra-abdominal pressure (typically 12-15 mmHg), controls gas flow rate, and provides safety alarms for pressure limits. Modern insufflators feature digital displays, pressure sensors, and automatic shut-off mechanisms to prevent over-insufflation. The device connects to the CO₂ source and the patient through sterile tubing and maintains pneumoperitoneum throughout the procedure.
