Abstract
An apparatus for insufflating a body cavity with an insufflation gas comprising an insufflation device for delivering the insufflation gas to the body cavity. To detect possibly critical states in the body cavity, the apparatus is designed to withdraw a measuring gas from the body cavity. A measuring device having a gas sensor serves for measuring an additional substance contained in the measuring gas in addition to the insufflation gas and for outputting a measuring signal as a function of the additional substance.
Claims20
An apparatus for insufflating a body cavity with an insufflation gas, comprising
- an insufflation device, having
- a delivery line for delivering the insufflation gas to the body cavity, and
- a withdrawal line for withdrawing a measuring gas from the body cavity;
- and
- a measuring device for measuring an additional substance contained in said measuring gas in addition to said insufflation gas and for outputting a measuring signal as a function of said additional substance, wherein said measuring device comprises a gas sensor designed to detect a compound selected from the group consisting of methane (CH4), nitrous oxide (N2O) and mixtures thereof.
A method for measuring a state of an insufflation gas comprising the following steps:
- providing the insufflation gas for delivery to a body cavity by an insufflation device,
- providing a measuring gas withdrawn from said body cavity for a measuring device by said insufflation device,
- measuring an additional substance contained in said measuring gas in addition to said insufflation gas, and
- outputting a measuring signal as a function of said additional substance, wherein said additional substance is selected from the group consisting of methane (CH4), nitrous oxide (N2O) and mixtures thereof.
