Title:
CORRUGATED TUBE
Document Type and Number:
WIPO Patent Application WO/2019/007311
Kind Code:
A1
Abstract:
A corrugated tube (3). The corrugated tube (3) is a hollow tube formed by connecting a plurality of ridges and a plurality of grooves alternately. A protrusion is provided in the middle of the end face of the tail end of the corrugated tube (3). The first part of the head end and the last part of the tail end of the corrugated tube (3) are both ridges. The widths of the first ridge of the head end and the last ridge of the tail end are both greater than the thickness of the corrugated tube (3), so as to prevent the tail end and the head end of the corrugated tube (3) from becoming sunken inwards when the air pressure in the corrugated tube (3) decreases. The corrugated tube (3) cooperates with other joint rehabilitation exercise aids, and is forced to be compressed or stretched by controlling the air pressure inside the corrugated tube (3), so as to drive the joint of a patient to move, thereby helping the patient to perform rehabilitation training.
