Title:
TRACHEA SUCTION CATHETER
Document Type and Number:
Japanese Patent JPS54112588
Kind Code:
A
Abstract:
The invention relates to a tracheal suction catheter comprising a flexible tube whose outermost portion has a side bend forming a knee on the tube, an aperture being provided in the tube wall adjacent the knee. The object of the invention is to provide a construction reducing as much as possible the risk of the catheter being clamped to the mucosa, and according to the invention this is achieved by the tube wall immediately around said aperture being sunk with respect to the cylindrical surface of the tube. Suction from the mucosa is thus spread over a greater area, and the aperture itself is spaced from the mucosa ensuring that the mucosa is not damaged, neither during insertion nor during suction.
