Definitions

  • This invention relates to a chair-shaped device for pulling a lumbar vertebra.
  • a conventional chair type towing device for example, is disclosed in the prior art document 1 ( JP-A-2013-215632 , see FIG. 28 ).
  • User's buttocks are held to sitting unit 9 by closing waist harness 6.
  • the arm contact 17 is moved to the armpit of the user.
  • the landing table 52 is tilted backward.
  • the separation driving unit 5 moves the buttock portion 9 downward and tows the lumbar vertebra of the user.
  • the waist pad 25 held by the waist mat 26 is wound up by the winding unit 24 connected to the seat belt 23 at a conventional chair type towing device (Japanese Unexamined Patent Publication No. H5-49669 , see Fig. 29 ).
  • User's pelvis is held by holding the waist of the user with the waist pad 25 and the waist mat 26.
  • the waist pad 25 can be twisted at the front portion (the stomach side of the user) toward the user's upper body side during towing. As a result, the user's pelvis can't be held properly.
  • a conventional bed type towing device for example, is disclosed in the prior art document 2 ( JP-A-Hei-5-49669 , see FIG. 31 ). It is composed of a bed 19 and a main body 20. An arm contact unit 21 and a hip contact unit 18 are used at the treatment. The arm contact unit 21 is fixed on the bed 19. Abed mat is divided into two and placed on the frame.
  • the user's lumbar vertebra is towed by pulling the hip contact unit 18 with the lower mat being movable in the longitudinal direction of the frame.
  • the lumbar vertebra of the user is on the boundary between the upper and lower mat.
  • the hip contact unit 18 being attached to the user's waist is connected to the main body 20 via the tow wire 22.
  • the upper body of the user is fixed by the arm contact unit 21. In this state, the towing device is operated to tow the lumbar vertebrae.
  • the hip contact unit 18 is held around the pelvic portion and pulled in the toe direction at a conventional bed type towing device. There was a possibility that it could not be pulled at an appropriate angle depending on the lying position on the bed or the towing position of the main body 20. In addition, though a triangular mat 27 for placing the towing posture at the semi-Farrar position is disposed below the buttocks of the user, this triangular mat 27 was impossible to accurately hold the pelvis of the user with the hip contact unit 18.
  • the chair-shaped lumbar vertebra traction device of the present invention is provided with an upper body holding unit to hold user's upper body on a backrest, a waist holding unit to hold the user's waist, a separating drive unit to separate the backrest and a seat including the loin guard from each other and a waist pulling unit to pull the waist holding unit toward user's buttock side, wherein the upper body holding unit can be slid along the backrest in order to adjust the proper position for users' height and the waist pulling unit pulls the waist holding unit in a predetermined angle against the backrest with the seat keeping user's lower body.
  • the seat 1 for supporting the waist and lower limbs of the user, a chair-like landing table 52 having a backrest 2 for supporting the user's back, a base unit 3 on which the landing table 52 is placed and a tilting mechanism 4 for tilting the landing table 52 toward the back side are provided.
  • a separation driving unit 5 is provided for separating the buttock portion 9 and the backrest 2.
  • a waist holding unit 6 is provided to hold the waist of the user on the seat 1.
  • An armpit holder 7 for supporting the armpit of the user is provided so that the body of the user does not shift downward. The armpit holder can be moved along the backrest 2 in order to adjust the proper position for various users' height.
  • An operation unit is provided to input and display the treatment conditions.
  • a control section is provided for controlling the tilting mechanism unit 4, the separation driving unit 5 and so on.
  • the seat 1 is constituted by the loin guard 8, the buttock portion 9, and the lower leg rest portion 10.
  • the waist holding unit 6 is configured to hold the waist circumferentially and cover the pelvis (see FIG. 2 ). It might be tighten automatically or manually.
  • a wire or belt (waist pulling unit) 11 is attached to two lateral sides of the waist holding unit 6. The wire or belt 11 is towed to the buttock portion 9 side and the user's ischium is pressed against the buttock portion 9 when pulling the lumbar vertebrae. In that state, the vicinity of the iliac crest of the user is towed downward using the waist holding unit 6. It can perform properly to tow with the waist held by the buttock portion 9 and the waist holding unit 6.
  • the waist holding unit 6 is towed toward the buttock portion 9, the waist holding unit 6 is not unreasonably twisted toward the upper body side with respect to its connecting point set in the loin guard 8. Therefore, it can tow the user's waist downward accurately.
  • the waist holding unit 6 is not necessary held on the loin guard 8 (see FIG. 3 ).
  • the waist holding unit 6 covers the waist of the user all around to tow to the buttock portion 9 side. Therefore, the waist portion of the user can be pulled downward even if the waist holding unit 6 is separated from the loin guard 8. Also, separating the waist holding unit 6 from the loin guard 8 make it possible to cover the vicinity of the iliac crest properly regardless of the height of the user or the size of the waist part.
  • the waist holding unit is not pulled downward. Therefore, it is necessary to tightly hold the circumference of the waist strongly.
  • the iliac crest and the sciatic bone of the user are held between the waist holding unit 6 and the buttock portion 9 so that it can be held accurately even without tightening as strongly as previously.
  • the triangular mat contacting the lower portion of the user is not fixed on the bed. Therefore, it can be moved correspondingly when the buttocks of the user is moved in the foot direction during towing. However, it can't return to the head side automatically on loosening after towing.
  • the triangular mat can't follow the movement of the buttocks of the user well so that the contact between the buttocks of the user and the triangular mat becomes unstable. Therefore, it is difficult to hold the waist of the user near the iliac crest and the sciatic bone accurately.
  • the towing operation is performed in a state where the user is on the seat 1 regardless of the height of the user.
  • the waist pulling unit (wire or the belt) 11 is connected to the fixed pulling position 15 (usually using a pulley) fitted on the landing table 52 to keep a proper pulling angle as shown in FIG.4 . Therefore, height of user hardly affect the towing angle.
  • the waist pulling unit 11 pulls the waist holding unit 6 in a predetermined angle of about 20 to 40 degree against the backrest 2 with the seat 1 keeping user's lower body as shown in FIG.4 .
  • the predetermined angle against the backrest 2 is set before the user sits down and is then not changed until the user leaves the seat 1 again.
  • the wire or the belt 11 is connected to the upper body holding unit 7 via the pulley 12 to pull the waist holding unit 6.
  • the upper body of the user is pulled upward by the upper body holding unit 7. (See FIG.5 )
  • the waist of the user is pulled downward by the waist holding unit 6. Since both the upper body and the waist are simultaneously towed, the amount of movement of the upper body side could become smaller.
  • the connection between the upper body holding unit 7 and the waist holding unit 6 by the towing wire or belt 11 can short the idle running distance until the starting the tensile force after starting the pulling. It can reduce unnecessary pulling action.
  • the buttock portion 9 is movable with respect to the landing table 52, the upper body and the waist portion can be effectively separated.
  • the angle of the thigh with respect to the lumbar can be changed so that the lumbar vertebrae L1 to L5 can be treated selectively (See FIG. 6 ).
  • Changing the attachment angle of the buttock portion 9 with respect to the loin guard 8 can pull on one or more of the lumbar vertebrae L1 to L5 selectively, depending on the selected attachment angle.
  • the towing angle on the casing (the landing table 52 and the backrest 2) is fixed. Therefore, it is possible to tow accurately regardless of the angle of the buttock portion 9.
  • upper body on the backrest 2 can be maintained more surely by using chest band together. Therefore, the pain of the armpit can be reduced in comparison with the traction by the armpit holder 7 alone.
  • an air bag or the like in order to hold the shoulder and the upper arm make it possible to suppress the collapse of the posture during the towing (See FIG. 25 ).
  • FIG. 7 It has a landing table 52, a backrest 2, a seat 1 (general term of the loin guard 8, the buttock portion 9 and the lower leg rest portion 10) on the landing table 52, the armpit holder 7 that can move along the backrest 2 to adjust to various users' height, a waist holding unit 6 on the loin guard 8, a belt retractor (not shown) for tightening the waist holding unit 6 around the user's waist, a tension unit 32 on the base unit 3 or the landing table 52 for applying traction force to the wire or belt 11 to pull the waist holding unit 6 toward the buttock portion 9 side and a load detection unit (not shown) for detecting the tension of the wire or belt 11.
  • the backrest 2 is tilted to the treatment position by the tilting mechanism 4 so as to adjust the angle of the landing table 52 to the base unit 3 (See FIG. 8 ). Tilting angle of the landing table 52 is detected and monitored by the optical sensor, the limit switch, the motor pulse or the like.
  • the armpit holder 7 can be moved to user's armpit position (See FIG. 9 ). In particular, at first the armpit holder 7 is in an upward state without being inserted to user's armpit. Next, the contact state between the cam at the root of the armpit holder 7 and the roller on the backrest 2 is changed for arm 54 to turns down to fall along the underarm of the user.
  • the arm contact 17 moves to the armpit position of the user to hold the upper body properly. It can be monitored to be moved to the appropriate position by measuring the motor current or the load of the drive unit.
  • the backrest 2 is tilted to pull the upper body of the user.
  • the backrest 2 is tilted to the horizontal state, the user may think its head has dropped too much.
  • backrest 2 also should be inclined upward by an appropriate angle, at least about 10 degree preferably about 20 degree, against the horizontal level with the landing table 52 being tilted by the tilting mechanism 4. Further, the backrest 2 is to be moved by the driving portion 55 along with the landing table 52.
  • the frictional force between the back of the user and the surface of the backrest 2 can be used to hold the upper body at the towing motion. So, the holding points of the upper body can be prevented from concentrating only on the armpit of the user to reduce the pain around the armpit.
  • the loin guard 8 can move freely on the landing table 52, friction between the body waist and the loin guard 8 can make the seat 1 to follow the movement of the user effectively (see FIG. 12 , FIG. 13 ). It can be treated with keeping user's initial posture, since it keeps no gap between the buttocks and the buttock portion 9.
  • the backrest 2 is operated with the loin guard 8 being free and motion range of the loin guard 8 is limited by using the mechanical stopper so that there is little need to move the seat upward to the initial position at the end of the treatment
  • the seat 1 can follow the user's body to keep contact with the buttocks and thighs closely in towing. Additionally, the seat 1 does not move further than the limited position of the foot side. Therefore, the position of the seat 1 is not too low for a user to stand up at the end of the treatment. As a result, there is no need to be forced to move the seat 1 upward a lot to the initial position (backrest side) at the end of the treatment, and it can reduce the shrinking of the lumbar vertebrae.
  • the hip joint angle can be 90 degrees as for both a hip joint angle and a knee joint angle in towing. It is also preferable to change the hip joint angle depending on the user's body shape, the state of the lumbar vertebra (lordosis) or the treating portion of at least one of the L1 to L5. It is possible to change the towing posture by changing the angle between the loin guard 8 and the buttock portion 9 (see FIG. 14 and 15 ). When changing the angle between the buttock portion 9 and the loin guard 8, unless the angle is changed around the hip joint as an axis, it can displaces a close contact between the seat and the thigh. Therefore, the angle of the buttock portion 9 to the loin guard 8 is changed around the hip joint as an axis as shown in FIG. 16 and 17 .
  • the distances change to be a ⁇ b ⁇ c ⁇ d, and the contact position between the buttock portion and the thigh portion changes as shown in FIG. 17b , therefore, the back surface of the thigh slides from the buttock portion, and the sitting posture is to be changed.
  • the lower leg rest portion 10 is connected to the buttock portion 9. It is possible to adjust the angle of the knee joint to 90 degrees according to the body type (thigh length) by means of the driving part mounted between the buttock portion 9 and the lower leg rest part 10. Additionally, the angle of the lower leg rest part 10 to the buttock portion 9 is to be sharped at the end of the treatment to make it easy for user to stand up.
  • the waist holding unit 6 holds the whole waist part mainly by holding the iliac crest.
  • the waist holding unit 6 can be connected to the loin guard 8. It is also possible to mount the waist holding unit 6 separately from the loin guard 8.
  • the waist holding unit 6 is connected to the loin guard 8
  • the abdomen side of the holding unit 6 is not twisted toward the upper body side during the towing with the connection point between the holding unit and the loin guard as a fulcrum and the waist portion can be held with relatively little force in order to keep the predetermined traction angle.
  • Waist holding unit 6 has an area 41 made of hard material and an area 42 made of soft material.
  • the branch belt 45 (the branch belt 45 is a part of the wire or belt 11) is fixed to a plurality of fixing points 43 on the area 41.
  • the waist holding unit 6 properly holds the pelvis (near the iliac crest) and the wire or belt 11 is pulled through the pulley 12 using connection point 44. Therefore, it is possible to suppress unnecessary direction force with respect to the pelvis during pulling.
  • the wire or the belt 11 is fixed at the three fixing points 43a, 43b, 43c (See FIG. 19 ).
  • there is only one fixed point (holding point) there is a possibility that the waist holding unit 6 will be twisted depending on how the waist holding unit 6 is attached to the waist of the user.
  • a plurality of points on the waist holding unit 6 are fixed (held) by a wire or a belt 11 so as to tow the iliac crest in a wide range (see FIG. 19b ).
  • the connection point 44 of the branch belt 45 is arranged on a line between the pulling point on the pulley 12 and the fixing point 43a or between the pulling point on the pulley 12 and the point ranged from 43a to 43c. Therefore, unnecessary rotation does not occur at the pelvis during pulling.
  • twisting of the waist holding unit 6 can be suppressed. As it holds the iliac crest in a wide range, it can accurately tow (pull) the iliac crest.
  • the area 41 contacting the iliac crest (the portion connecting 43a, 43b, 43c points) is made with a stretchable stiff material while the area 42 is made of an elastic material.
  • the hard material is used for the part in contact with the iliac crest not to stretch unreasonably. Therefore, the pelvis (near the iliac crest) can be accurately held.
  • the soft material portion improves fitting so that it can alleviate the feeling of cramping. If every portion is made of stiff material, it compresses unnecessarily and impairs the comfortability. Conversely, if every portion is made of stretchable material, it loosens the holding of the pelvis (near the iliac crest) and prevents proper fixation.
  • this example is not limited to the configuration in which the points 43b and 43c on the waist holding unit 6 are connected by a belt or the like.
  • connection point 44 should only be satisfied with being arranged on a line between the pulling point on the pulley 12 and the point 43a or the point ranged from 43a to 43c.
  • the mounting point on the waist holding unit is not limited to only 2 or 3 points.
  • the wire or belt 11 attached to the waist holding unit 6 is not limited to a configuration being pulled through a pulley. If the waist holding unit 6 is not twisted in towing, for example, the wire or the belt 11 can be fixed at a point somewhere under the buttocks portion 9.
  • the waist holding unit 6 is connected to the belt winding portion 59 (See FIG. 22 ). If the belt winding portion 59 is movable in the up and down direction with respect to the loin guard 8, the waist holding unit 6 can be fitted more accurately according to the user's body shape.
  • the belt winding portion 59 extends the winding belt from the center of the loin guard 8 to the left and right. Both belts are connected with the buckle 60 in front of the user, and the belt is wound using the motor of the belt winding unit. Therefore, it makes equal tension (belt winding force) for right and left. It also can be tightened by hand without using the belt winding portion 59.
  • the tension unit 32 is mounted on the base unit 3 or the landing table 52.
  • the wire or belt 11 being wounded in the tension unit 32 is connected to the waist holding unit 6 via the pulley 12 mounted on the landing table 52 (See FIG. 23 ).
  • the waist holding unit 6 By connecting the waist holding unit 6 to the wire or the belt 11 of the tension unit 32, proper tension is generated in the wire or the belt 11 by the motion of the backrest 2.
  • pulling force is generated at the lumbar vertebra by using the waist holding unit 6.
