PROBLEM TO BE SOLVED: To provide assist bands 1 and 10 for an ED patient, which have simple structure, are easily attached and detached, and are washed without requiring time and labor.SOLUTION: Each of the assist bands 1 and 10 for an ED patient comprises a fastener 2, a ball chain 3 and a protective cover 4, wherein the fastener 2 of the assist band 1 comprises a fastener body 5 and a lock body 6, and the fastener 2 of the assist band 10 comprises a fastener body 7 and the lock body 6. By holding parts 5j and 7j provided respectively on the rear sides of base parts 5a and 7a of the fastener bodies 5 and 7, the end ball parts 3a of the ball chains 3 are hooked and the ball chains 3 are hung. By pushing and bending left and right arm parts 5b, 5e, 7b and 7e of the fastener bodies 5 and 7, the range in which left and right stop parts 5c and 5f overlap and the range in which left and right stop parts 7c and 7f overlap, are each widened, left chain hole 5d and right chain hole 5g are roughly matched with each other, and left chain hole 7d and right chain hole 7g are roughly matched with each other, and the ball chains 3 are respectively inserted into the matched holes. Thereafter, the lock bodies 6 are placed respectively near the left and right stop parts 5c, 5f, and left and right stop parts 7c, 7f, and the bend of the left and right arm parts 5b, 5e, 7b and 7e is limited. Also, the outer peripherals of the rings of the protective covers 4 are opened.COPYRIGHT: (C)2012,JPO&INPIT【課題】構造が単純で、簡単に脱着することが可能で、洗浄に手間のかからないED患者用の補助バンド1、10を提供する。【解決手段】留具2と球鎖3と保護カバ4とからなるED患者用の補助バンド1、10であって、留具2は留具本体5、7とロック体6とからなるものとする。留具本体5、7の基部5a、7aの後側に設けた保持部5j、7jによって、球鎖3の端球部3aを掛け止め球鎖3を吊り下げる。留具本体5、7の左右腕部5b、5e、7b、7eを押して撓ませることにより、左右止部5c、5f、7c、7fが重なり合う範囲を広げ、左鎖穴5d、7dと右鎖穴5g、7gとを概一致させて球鎖3を通す。その後、ロック体6を左右止部5c、5f、7c、7f近くに置いて、左右腕部5b、5e、7b、7eの撓みを制限する。また、保護カバ4の環の外周を開放する。【選択図】図1
