Japanese Patent JP7011673
Kind Code:
B2
Abstract:
Disclosed is a corrugated tube (3), which corrugated tube (3) is a tube, hollow inside, formed of several crests and several troughs connected alternately, wherein the middle of an end face of a tail end of the corrugated tube (3) is provided with a boss; and both a first section of a head end and a last section of a tail end of the corrugated tube (3) are crests, with the width of both the crest of the first section of the head end and the crest of the last section of the tail end being greater than the thickness of the corrugated tube (3), preventing the tail end and the head end of the corrugated tube (3) from collapsing inwards when the air pressure in the corrugated tube (3) decreases. As such, the corrugated tube (3) cooperates with other joint rehabilitation exercise aid parts to help patients perform rehabilitation training by controlling the air pressure in the corrugated tube (3), such that the corrugated tube (3) is forced to compress or stretch and drives the patient's joints to perform exercise at the same time.
