Abstract
A pneumoperitoneum apparatus includes: a gas feeding conduit; a gas feeding flow rate variable section; a first pressure measurement section coupled with the gas feeding conduit; a conduit for pressure measurement; a conduit for pressure measurement coupling part coupled with the conduit for pressure measurement; a second pressure measurement section coupled with the conduit for pressure measurement coupling part, and configured to measure pressure in the conduit for pressure measurement; a gas leaking part configured to communicate the gas in the conduit for pressure measurement to an outside to leak the gas in the conduit by a predetermined leakage; and a control section configured to determine that the conduit for pressure measurement is crushed when pressure measured by the second pressure measurement section is smaller than a predetermined threshold.
