Abstract
The present invention relates to an apparatus and method for insufflating fluid media into a cavity of a human or animal body, particularly the abdonimal cavity. A single hollow needle is utilized for intermittently insufflating the gas into the body cavity. Thereafter the flow of gas is interrupted and then the needle is connected with a pressure measuring device to determine both the static and dynamic fluid pressure of the body cavity. The amount of fluid insufflated can also be measured with the aid of the same hollow needle. Using the needle for insufflating will insure that the measuring will be correct since the gas during insufflating will blow any blood clots and/or tissue into the body cavity. The conduit leading to the needle may be split in a number of branches to insufflate gas at desired different pressures and/or volumes which again are variable. Most of the operation can be effected automatically. A display panel giving a visual indication of the parameters can also be provided.
