<p><P>PROBLEM TO BE SOLVED: To provide a traction machine for medical use capable of easily and sanitarily adjusting traction force. <P>SOLUTION: The traction machine 11 for medical use includes: a freely rotatable rotary shaft 12 arranged at a fixed position; and a reel 13 and a pulley group body 17, where a plurality of pulleys different in diameter are integrally arranged in an axial direction, which are respectively integrally and rotatably attached to the rotary shaft 12. One string body 14, to which the traction-exerted part of a person to be treated is connected, is wound around the reel 13. The other string body, to which a weight is connected, is wound around one of the pulleys 16 in the pulley group body 17 in a direction for winding one string body 14. Thus, the machine exerts traction on the traction-exerted part of the person to be treated. The pulley group body 17 is constituted of the plurality of pulleys 16 different in diameter, thereby adjusting the traction force of the traction machine 11 for medical use only by rewinding the other string body around the pulley 16 with the different diameter. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
