INSUFFLATION OF BODY CAVITIES

摘要

Apparatus used in insufflation comprises an insufflator (12) for generating an insufflation gas such as carbon dioxide and an aerosol generator (2) for aerosolising a fluid and entraining the aerosol with the insufflation gas which is delivered during surgery. The aerosol generator (2) comprises a vibratable member (40) having a plurality of apertures extending between a first surface and a second surface. The fluid may comprise a therapeutic or prophylactic agent. A controller (3) is used to control the operation of the aerosol generator (2). The controller (3) controls operation, of the aerosol generator (2) responsive to the flow of insufflation' gas such as detected by a flow sensor (11). The pulse rate at a set frequency of. vibration of the vibratabie member (40) is controlled.
