Description

  The present invention relates to a pelvic correction device for preventing or treating various painful symptoms caused by changes in the condition of the pelvis.

  All of the load on the upper body is applied to the waist of a human body walking on two legs. For this reason, the influence by the load to the sacrum and the pelvic joint part in the lower end part of the spinal column constituting the lumbar part is also great. FIG. 8 shows a schematic structure of the sacrum and the pelvis of the pelvis, and the joint portions 300 of the sacrum 100 and the pelvis 200 are formed by combining surfaces called “ear upper surfaces”. That is, the joint portion of the sacrum 100 and the pelvis 200 is formed by the ear-like surface of the sacrum 100 and the ear-like surface of the iliac bone 200b occupying the rear upper part of the hipbone 200a constituting the pelvis 200.

  And, the excessive load on the pelvis from various unfavorable directions changes the state of the ear surface, and various painful symptoms occur. For example, an excessive load occurs when the waist is twisted or when a heavy object is held at the middle waist, which causes the state of the ear-like surface to deviate from an appropriate state and causes distortion of the pelvis.

  Therefore, conventionally, the sacrum and iliac bones are tightened from the direction of the right angle by the fingers and arms of the person performing the treatment, and the sacrum and iliac bones are firmly bonded by eliminating the looseness of the ear surface. The pelvis is being corrected.

  However, since the pelvis is corrected by pressing the waist with the force of a person's finger or arm to correct the pelvis, it is difficult to apply a sufficient pressing force stably at a certain angle, and it is difficult for an expert. Even that is difficult. In addition, this is particularly difficult for people who have strong muscles such as athletes or who have large muscles.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pelvic correction device that can perform simple treatment regardless of the level of skill of the person performing the treatment.

In order to achieve the above object, a pelvic correction device according to claim 1 comprises:
A pair of push bars that are arranged on the upper side, with a bed for the person to be corrected lying down and two upper and lower positions that are shifted to the right and left sides of the person to be corrected lying on the bed so that the vertical position can be adjusted. Is a state in which the pressing portion at the tip is inclined downward by a predetermined angle, and the pair of push rods arranged on the lower side is the object to be laid down in a state where the pressing portion at the tip is inclined upward by a predetermined angle. who is movably held to the pelvis direction, and urging the urging a push rod that have a pressing portion for transmitting a pressing force to the pelvic region is brought into contact with the straightening subject to the distal end portion, the movement of the push rod And urging means , wherein the pelvis of the person to be corrected laid down by the push rod is pushed from two left and right positions using the urging force of the urging means .

With this configuration, it is possible to apply a pressing force to the pelvis part from both the left and right sides of the person to be corrected lying on the bed by a moving operation in which the two push rods are urged on both sides . Then, this pressing force pushes the upper push rods arranged at two positions on the left and right, respectively, so that the lower push rod is pushed downward and obliquely downward, and the lower push rod is pushed upward and obliquely upward. This makes it possible to apply a well-balanced pressing force from four directions toward the pelvis . Further, since this pressing force depends on the urging force of the urging means, it is possible to perform the pressing operation by the pressing bar with the pressing force appropriately corresponding to each correction subject by variously adjusting the urging means. For example, the pelvis can be corrected while maintaining an appropriate stress state between the pelvis and the sacrum.
Further, since the vertical positions of the push rods can be adjusted, the push members can be adjusted so as to accurately transmit the pressing force to the pelvis of the human body.

  The pelvis correction device according to claim 2 is the pelvis correction device according to claim 1, wherein the push rod installation structure includes a push rod mounting column provided with a slit extending in the vertical direction penetrating in the lateral direction, and A push rod holding portion that has a tubular body capable of sliding movement of the push rod and is fixed so that the vertical position can be adjusted in the slit.

  According to the said structure, the structure which enables the said push bar to move to the direction of the pelvis of the correction subject who is sleeping on the bed from the both sides of the bed with a fixed inclination angle can be achieved with a simple structure.

  In particular, the height of the push rod holding part can be easily adjusted by moving in the slit, and the push bar slides and moves in the tubular body provided in the push rod holding part. The pelvic part can be pressed stably.

  The pelvis correction device according to claim 3 is the pelvis correction device according to claim 1 or 2, wherein the urging means for urging the movement of the push bar is a pair arranged on both sides of the bed. It is characterized by comprising a stretchable member that is installed so as to be bridged between the push rods so as to bias the push rods that are formed.

  With such a configuration, the push bar can be biased to move toward the pelvis with a simple structure. The elastic member used is a belt-like rubber or a spring, and it is preferable that various biasing forces can be selected.

Also, during orthodontic treatment, the person to be corrected on the bed lies in the supine or prone state, but the pressure from the left and right sides to the pelvis in that state is simultaneously from the position shifted up and down It is preferred to do so. Therefore, it is possible to perform an accurate correction treatment with a good balance by applying a pressing force in a state where it is tilted from the left and right by two push bars arranged on the both sides of the bed so that the vertical positions are shifted.

  According to the pelvic correction device of the present invention, a stable and balanced pressing force can be easily applied to a desired part of the pelvis from two left and right positions at a fixed angle, and correction of the pelvis can be performed without requiring skill. It can be done easily and reliably.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show an embodiment of a pelvic correction device according to the present invention, FIG. 1 is a perspective view of the pelvis correction device in actual use, and FIG. 1 shows a rear view of FIG.

  The pelvic correction device shown in FIGS. 1 and 2 has a rectangular bed 1 on which a human body M lies, and the bed 1 is supported by four support legs 2 and is reinforced between adjacent support legs 2. The member 3 is constructed.

  On the bed 1, push bar mounting columns 4 are erected on both the left and right sides. The push rod mounting column 4 is erected at a position close to the left and right sides of the intermediate position of the bed 1 and at a position where the human body M can lie with a margin. An upper reinforcing member 5 is horizontally stretched between the push rod mounting columns 4, and both ends of the upper reinforcing member 5 are fixed to the upper ends of the pair of push rod mounting columns 4 by bolts 13.

  The push rod mounting column 4 has a hollow structure, and a push rod 7 is mounted on the rod mounting column 4 so that the vertical position can be adjusted. A total of four push rods 7 are installed on each of the left and right sides of the bed 1, and the tip of the push rod 7 is installed so as to face the pelvis of the human body M.

  3 and 4 show an example of a structure for attaching the push rod 7 to the push rod mounting column 4. The push rod 7 is installed by a push rod holding portion. The push rod holding portion includes a block body 10 and a tubular member 20 that is attached to the block body 10. The tubular member 20 forms a moving passage for the push rod 7 and is configured so that the push rod 7 can slide and move through the passage.

  The push rod mounting column 4 has a substantially rectangular outer shape, and has a hollow structure as shown in the figure. The opposing side walls 4a and 4b are formed with slits 4c and 4d extending in the vertical direction, respectively, so that the block body 10 can move up and down in the push rod mounting column 4. The block 10 is made of, for example, aluminum.

  The block body 10 is fixed to the push rod mounting column 4 by a plate 12 and screws 11. That is, it is fixed to the push rod mounting column 4 by being fastened to the block 10 through the slit 4 c of the push rod mounting column 4.

  Since the push bar 7 is attached to a portion of the tubular body 20 that is fixedly penetrated to the block body 10, the height position of the push bar 7 is also adjusted by adjusting the slit height position of the block body 10. The height position of the push rod 7 is also adjusted by adjusting the height position. The push rod 7 penetrates the slits 4 c and 4 d together with the tubular body 20, and an inclination angle (angle θ) is set by the inclination of the tubular body 20.

  As shown in FIG. 4, a pressing member 8 that directly contacts the human body M and transmits the pressing force of the pressing bar 7 to the human body M is provided at one end of the push bar 7. The contact surface of the pressing member 8 with the human body M is formed in a substantially spherical shape so as to relieve the feeling of pressure when the waist of the human body M is pressed.

  Each of the four push rods 7 includes a pair of upper push rods 7-1 and a pair of push rods 7-2 on the lower side. The upper push rod 7-1 is installed so as to be inclined so that the pressing member 8 side which is the tip portion is directed downward by a predetermined angle, and the lower push rod 7-2 is provided so that the pressing member 8 side which is the tip portion is directed upward by a predetermined angle. It is installed at an angle. This inclination angle is set so that a pressing force can be applied accurately and in a balanced manner from four directions to the correction subject who sleeps on the bed 1, that is, the pelvis of the human body M.

  As means for urging the push rods 7 in the direction of pulling each other, the belt-shaped rubbers 9-1 and 9-2 are respectively arranged between the upper pair of push rods 7-1 and the lower pair of push rods 7-2. It is built in. As a result, the push rods 7 are always drawn toward each other. That is, when the human body M lies down, each push bar 7 presses the belt-like rubber 9 against the pelvis of the human body M by a pulling force. The length of the push rod 7 is also set to a length that can be surely pressed regardless of the size of the human body M. The urging means is not limited to the belt-like rubber 9, and any means that can appropriately apply an urging force to the push rod 7 can be used, and a spring or the like can be attached.

  In the present embodiment, since the push bar 7 is pushed from the lower side to the human body M, the upper portion 22 is formed in the central portion where the person to be corrected of the bed 1 lies.

  An actual use operation of the pelvic correction device according to the embodiment having the above-described configuration will be described with reference to FIGS. 1 and 2. First, the upper and lower push rods 7 are picked by hand and pulled outward against the elastic force of the belt-like rubber 9. In this state, the human body M lies with its waist positioned between the push rod mounting posts 4. The prone or prone position is appropriately selected. Then, the height position of the push rod 7 is adjusted so that the pressing member 8 of the push rod 7 hits the desired left and right pressing portions of the waist to accurately transmit the pressing force to the pelvic part of the human body M, and the screw 11 is used at that position. Fixed.

  Next, when the hand is released from the push rod 7, the push rod 7 slides in the tubular body 20 by the contraction force of the belt-like rubber 9, and the pressing member 8 applies a pressing force to desired upper and lower and left and right pressing portions. The direction in which the pressing force is applied is the above-described inclination angle θ. By this pressing, the pressing force is applied at an appropriate angle from the iliac bones on both sides to the sacrum located in the center.

  FIG. 5 is a schematic AA cross-sectional view of the pelvis and sacrum shown in FIG. 8, in which the upper side is the back side and the human body M is prone. The pair of push rods 7 press the portion of the iliac bone 200b at a predetermined inclination angle while applying the pressing force of D-1, 2 from the top, bottom, left and right as indicated by arrows U-1, 2 and D-1. As a result, the ear-like surface 300 which is the joint portion between the pelvis 200 and the sacrum 100 can be brought into an accurate state. That is, loosening of the ear-like surface 300 between the sacrum 100 and the iliac 200b is accurately eliminated by this balanced pressing, and the pelvis 200 is corrected.

Thus, simultaneously pressing the pelvis 200 from both the upper side and the lower side has a good effect in order to make the state of the ear-like surface 300 an accurate state. That is, it is possible to correct the looseness of the ear-shaped surface 300 with good balance and without bias.

FIG. 7 shows another configuration example of the pressing member 8 provided at the tip of the push rod 7. Is obtained by forming a small protrusion 8a to one edge so that it can be more accurately pressing the ends of the pelvis 2 00 acetabular 200a in a state in which the human body M shown in FIG. 6 is sleeping on his back . A force can be applied more accurately by pressing the small protrusion 8a so as to be caught on the edge of the hipbone 200a.

  As described above, according to the present embodiment, compared to pressing by only a human hand, the pressing rod 7 is pressed by a stable path due to sliding movement in the tubular body 20 and by the pulling force of the belt-shaped rubber 9. A pushing operation with an accurate and sufficient pressing force can be performed, and the correction of the pelvis becomes more accurate.

  In the present embodiment, as described above, the push bar 7 moves along the tubular body 20, and therefore the inclination angle θ depends on the inclination angle of the tubular body 20. However, it is preferable that the inclination angle θ is adapted to the size and shape of the human body M and can be changed and adjusted according to whether the human body M is leaning on the bed 1 or lying on its back. is there. In this case, angle adjustment is possible with the steel pipe of the block 10 by preparing the block provided with the tubular body 20 set to various inclination | tilt angles (theta). In addition, the correspondence between the human body M in the supine state and the prone state can be dealt with by changing the upper and lower installation states of the push rod mounting column 4.

  Next, the pressing force also needs to be changed by the human body M. That is, it is necessary to adjust the pressing force due to a difference in muscle mass due to exercise or a difference between men and women. In the present embodiment, the adjustment can be made by changing the number of belt-shaped rubber 9 attached or changing the belt-shaped rubber 9 to a different cross-sectional area.

  Similarly, when a spring is used as the urging means, it is possible to adjust by changing the number or changing to a spring having a different elasticity. Furthermore, a hydraulic cylinder with a pressure reducing valve can be used as the biasing means.

  Further, the height of the push rod 7 is configured such that the plate 12 is installed on the outer surface of the slit 4c portion of the push rod mounting column 4 and this is fixed to the block 10 with the screw 11, so that the screw 11 is twisted. The height can be easily adjusted with this simple operation.
