Abstract
A vent cycle indicator for a suction catheter formed by a sleeve connected between a collar having a wiper seal and a crosspiece. The suction catheter includes a vacuum connection member having a normally closed valve. A catheter tube is connected to the vacuum connection member and extends through the collar and crosspiece. The crosspiece is for connection to a ventilator such that during ventilation the indicator sleeve expands and contracts during the inspiration and expiration cycles. The protective sleeve may be provided between the collar and the vacuum connection member to keep the catheter tube enclosed.
