ABSTRACT:
Conventional endotracheal tubes are provided with improved proximal end connector units by which the endo tubes may be attached to breathing equipment or like fluid flow devices in a manner that mitigates interference with operations being performed on patients intubated with the endo tubes, such units comprising a straight, rigid, cylindrical distal end portion, a straight, rigid, cylindrical proximal end portion, a central tubular portion joining the distal end portion to the proximal end portion, the central tubular portion being bendable in an arc of at least 180.degree. without any substantial diminution of its effective lumen, such proximal end portion, distal end portion and central tubular portion all being integral and formed of the same thin, plastic material, the central tubular portion comprising a plurality of circumferential, angular segments each consisting of a pair of sides that are of unequal length, the central tubular portion being compressed lengthwise by having the shorter side in each segment folded back under its longer side.
