Endoscope tip pressure feedback control system for insufflated fluids and gases

摘要

Endoscopes are designed to deliver gas and fluid to body cavities or hollow organs during examinations and surgery to accomplish desired tasks. The delivery of gas and fluid potentially increases the body cavity or hollow organ ambient pressure to an injurious level. This invention senses the body cavity or intra luminal organ pressure and stops the flow of gas and/or fluid before injury can occur. Gas and fluid flow is re-established when the ambient pressure falls to a safe level.
