<P>PROBLEM TO BE SOLVED: To solve the problem that a neck traction machine having been used in Japan exerts traction by the air pressure of a compression pump and traction force using the air pressure cannot be used when the traction force is 5 kg or less, so that it has been desired that the traction is exerted within a safe traction force area being 5 kg or less. <P>SOLUTION: Traction is exerted on each patient by an optimum traction force by using multiple weights hanging inside a long pipe A. A step board B is stepped on to release the traction. One portion of a traction string F is allowed to be instantaneously cut when a fixed load is added thereby to secure safety. The traction is exerted within the safe traction force area being 5 kg or less, and the counter-clockwise turning and clockwise turning of the overhead traction string F are alternately electrically performed at a desired angle and turning speed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
