The present invention is a catheter having a tube and including mechanisms that provide precision control over insertion and retraction of the catheter tube. The catheter is particularly adapted for introduction into the pulmonary system. The catheter includes an insertion depth control mechanism that acts as a stop and provides a tactile indication to the person inserting the catheter tube that a predetermined position has been reached. The catheter also includes an anti-bunching mechanism to prevent bunching of a protective sleeve disposed around the catheter tube, thereby reducing interference from the sleeve during insertion of the catheter tube.

A neonatal suction adaptor with reduced deadspace allows tidal volume monitoring and synchronization to continue without substantial interference while a suction catheter is used. The adaptor includes a central housing disposed about a central chamber. A ventilation connector and an endotracheal connector are each secured to, and extend from, the central housing. Each tubular connector defines a passage connected with the central chamber. The connectors are sized and shaped to form press-fit connections with endotracheal tubes and ventilation monitors. The endotracheal connector includes a sleeve separated from a core by an annular recess configured to receive part of an endotracheal tube ventilation adaptor. A suction access tube is also secured to, and extends from, the central housing. The suction access tube is connectable to a wide variety of standard sleeved or exposed suction catheters. The adaptor's deadspace is reduced by utilizing a narrow core passage, by receiving portions of conventional monitors and tubes into the ventilation connector passage and the endotracheal connector annular recess, and by filling potential deadspace with the core. A valve may be seated in the central chamber to further reduce the deadspace.
