  The present invention relates to a supine cervical tractor that relieves cervical spine neuropathy by pulling the cervical spine while lying on its back.

It is generally known that pulling the cervical spine is effective as a countermeasure when the nerve inside the cervical spine is compressed. By pulling the cervical spine, the nerves are relieved and the numbness and stiff shoulders are alleviated.
Conventionally, when pulling the cervical spine, the patient sits on a chair and raises the patient's jaw part upward.

However, when lifting the patient's jaw, it is necessary to consider the weight of the patient's head, and the lifting force is 5 kg or more, but it is dangerous to keep pulling for a long time with a strong force of 5 kg or more. The chin is also uncomfortable.
Moreover, while receiving this treatment, the patient had to sit on a chair, could not relax, and was painful for the patient.
Also, the method of raising the head has a large structure, and it has been difficult to carry out easily at home. It took time to go to the hospital and it was difficult to continue treatment for a long time.

  The present invention has been devised in view of the problems as described above to solve the problems. The purpose of the invention is to pull the head while lying on its back, Suspension type cervical traction device that does not need to consider the weight of the part and can be pulled with less force than when pulling up, so there is no danger of traction, and it can be easily done at home by downsizing Is to provide. By pulling for a long time while sleeping and relaxing, it is considered that a painful intervertebral disc and the like can be easily recovered.

  In order to achieve the above-described object, the invention of claim 1 is provided with a slide plate that slidably mounts on the upper surface side of the machine frame in the front-rear direction, and slides the head placed thereon. A spiral spring that pulls the plate in a direction that pulls the head with a constant force is placed below the slide plate, and the slide plate is locked and unlocked in place by resisting the pulling force of the spiral spring. It consists of means provided with a stopper.

  According to the invention of claim 2, a slide rod is arranged in the machine frame in the front-rear direction, and a slide guide board that is engaged and guided by the slide rod and moves in the front-rear direction is slidably attached to the back. A slide plate for placing the head in the sleeping state is attached to the upper side of the slide guide board, and a spiral spring that pulls the slide plate for placing the head toward the direction of pulling the head with a constant force is arranged below the slide plate. The coil spring's coil end is connected to the lower surface of the slide plate, the release lever is provided on one side plate of the machine frame, and the tip side engages with the stopper hole attached to the slide plate to attract the spiral spring. And a means provided with a locking stopper that locks and unlocks the slide plate at a predetermined position.

  As is clear from the above description, according to the supine cervical tractor according to the present invention, the cervical vertebra can be pulled by pulling the head while lying on its back when extending the cervical vertebra. There is no need to consider the weight, and the traction force can be reduced with less force than when the head is pulled up.Therefore, there is no danger of traction, and it is possible to easily extend the cervical spine at home by downsizing. It can produce extremely practical and beneficial effects.

Hereinafter, the present invention will be described more specifically based on the best mode for carrying out the invention described in the drawings.
Here, FIG. 1 is a partially cutaway perspective view of a supine cervical tractor, FIG. 2 is a plan view of the supine cervical tractor, FIG. 3 is a side view of the supine cervical tractor, and FIG. FIG. 5 is a bottom view of the supine cervical traction device, and FIG. 6 is a bottom view of the supine cervical traction device during sliding.

  In the figure, the supine cervical tractor 1 is a device that pulls the head and pulls the cervical vertebra while lying on its back, and the machine frame 2, the slide rod 3, the slide guide board 4, and the slide that pulls on the head. The plate 5, a spiral spring 6 that pulls the slide plate 5, a locking stopper 7 that locks and unlocks the slide plate 5 at a predetermined position, and the like.

  The machine frame 2 has a square shape when viewed from the plane, and includes a left side plate 21 and a right side plate 22 arranged on the left and right sides, and a front side plate 23 and a rear side plate 24 arranged on the front and rear ends. Is done. The machine frame 2 is inclined obliquely upward toward the front, and the left and right left plates 21 and 22 are inclined obliquely upward toward the side connected to both ends of the front plate 23 when viewed from the side. Yes. Thus, since the machine frame 2 is inclined obliquely upward toward the front, the front plate 23 serving as the front end side of the machine frame 2 is higher than the rear plate 24 serving as the rear end side.

  Inside the machine frame 2 surrounded by the left and right plates 21 and 22 and the front and rear plates 23 and 24, for example, slide rods 3 each having a circular cross section are arranged on the left and right sides in the front-rear direction. The front ends of the left and right slide rods 3 are connected to the front plate 23, and the rear ends of the slide rods 3 are connected to the rear plate 24. The slide rod 3 functions to smoothly slide the slide plate 5 in the front-rear direction via the slide guide board 4.

  Each slide rod 3 is attached so as to be inclined obliquely upward toward the front in accordance with the inclination of the upper surface side of the machine casing 2. That is, the mounting height from the upper end of the front plate 23 with the high front end of each slide rod 3 is the same as the mounting height from the upper end of the lower rear plate 24 with the rear end of each slide rod 3. Due to the inclination of the slide rod 3, the slide plate 5 is inclined and slides.

  The left and right slide rods 3 are each slidably attached with slide guide panels 4 that are engaged and guided by the slide rods 3 and move in the front-rear direction. The slide guide board 4 functions to slide the slide plate 5 arranged on the upper side. Two slide guide boards 4 are mounted on one slide rod 3 with a gap in the front and rear direction.

  A slide hole 41 through which the slide rod 3 passes is formed in each slide guide panel 4 in the front-rear direction. The slide hole 41 has the same shape as the cross section of the slide rod 3, and for example, a circular hole is formed. Each slide guide board 4 slides on the slide rod 3 in the front-rear direction when the slide rod 3 penetrates.

  A guide connecting plate 42 for integrally connecting to the slide plate 5 disposed on the upper side of each slide guide panel 4 is integrally formed. The upper surface of the guide connection plate 42 in contact with the lower surface of the slide plate 5 is formed as a flat surface, and a screw hole (not shown) is formed to connect the fork slide plate 5 with, for example, a screw screw.

  The slide plate 5 is for placing the head in a state of lying on its back and forcibly pulling the placed head. As described above, the slide plate 5 is slidable by the slide rod 3 and the slide guide board 4 connected on the lower side thereof. The slide plate 5 for placing the head in the state of lying on its back is, for example, a rectangular flat plate, and for example, a hook-and-loop fastener 51 is provided in the left-right width direction in order to fix and attach the pillow a on which the back of the head is placed. It is attached in two places.

  As described above, the slide rod 3 that slides the slide plate 5 is attached obliquely upward toward the front, and therefore the slide plate 5 that slides along the slide rod 3 is also attached to the front front plate 23. It slides diagonally upward toward the rear and slides diagonally downward toward the rear rear plate 24. Further, as will be described later, the slide plate 5 is pulled obliquely upward toward the front.

  A spiral spring 6 that pulls the slide plate 5 on which the head is placed with a constant force in the direction of pulling the head is arranged inside the machine casing 2 below the slide plate 5. The center of rotation of the spiral spring 6 is connected to a spring attachment plate 61 attached to the center of the front plate 23. The spring mounting plate 61 is attached to the front plate 23 at a right angle, while the rotation center of the spiral spring 6 is attached to the spring mounting plate 61 at a right angle. That is, the rotation center direction of the spiral spring 6 is directed to the left and right side plates 21 and 22.

  A thin plate-like coil 62 is wound around the spiral spring 6 attached to the spring attachment plate 61 of the front plate 23 toward the front plate 23 with a constant force. The distal end side of the coil 62 extending from the spiral spring 6 toward the rear plate 24 is connected to the center of the lower surface of the slide plate 5 by a screw or the like. The slide plate 5 is always pulled through the coil 62 toward the front plate 23 to which the spiral spring 6 is attached.

  The spring force of the spiral spring 6 that pulls the slide plate 5 is substantially constant regardless of the sliding stroke of the slide plate 5. For this reason, the head placed on the slide plate 5 can always be pulled with a constant pulling force regardless of the stroke. Further, since the spring force of the spiral spring 6 does not need to support the head, it can be pulled with a slightly weak force, for example, 2 kg, and there is almost no danger or discomfort compared to the case where the head is pulled with a strong force. Absent.

  The locking stopper 7 functions to lock and release the sliding plate 5 at a predetermined position opposite to the direction of pulling the head by resisting the pulling force of the spiral spring 6. That is, when the locking stopper 7 is activated, the slide plate 5 is not pulled forward and does not move at a predetermined position even when the spring force of the spiral spring 6 is applied. When the locking stopper 7 is released, the slide plate 5 is instantaneously pulled by the spring force of the spiral spring 6 to be movable. The locking stopper 7 is provided in the center portion of the left side plate 21 in the drawing.

  The stopper stopper 71 has a stopper tip 71 passing through the left side plate 21 and reaching the side surface of the left slide rod 3 inside the machine frame 2. A stopper receiver 72 formed with a locking hole 72a in which the stopper tip 71 is inserted and locked is slidably mounted on the slide rod 3 where the stopper tip 71 of the locking stopper 7 reaches. The locking hole 72 a is formed on the side surface of the stopper receiver 72. The stopper receiver 72 moves together with the slide plate 5.

  A stopper receiver connecting plate 72b for integrally connecting to the slide plate 5 disposed on the upper side of the stopper receiver 72 is integrally formed. The upper surface of the stopper receiving connection plate 72b in contact with the lower surface of the slide plate 5 is formed as a flat surface, and a screw hole (not shown) is formed to connect the fork slide plate 5 with, for example, a screw screw. The stopper receiver 72 is integrally connected to the slide plate 5 through the stopper receiver connecting plate 72b and slides integrally.

  When the slide plate 5 pulled forward by the spiral spring 6 is returned to a predetermined stop position, the stopper tip 71 of the stopper 7 is smoothly inserted into the stopper hole 72a formed on the side surface of the stopper receiver 72. The stopper receiver 72 is formed with a guide inclined side surface 72c so that it can be engaged. The guide inclined side surface 72 c is formed integrally with the side surface on the rear half side of the stopper receiver 72.

  The side surface of the guide inclined side surface 72 c is inclined backward in a direction away from the left side plate 21 toward the rear from the same position as the side surface of the stopper receiver 72 when viewed from the plane. When the slide plate 5 is returned to the predetermined stop position, the most receding portion of the guiding inclined side surface 72c hits the stopper tip 71 of the locking stopper 7, and the stopper leading end 71 is located on the left side plate 21 side along the guiding inclined side surface 72c. After being pushed and retracted toward the side surface and guided to the side surface of the stopper receiver 72, it is possible to enter the locking hole 72a formed on the side surface.

  The locking stopper 7 is attached to the left side plate 21 with the stopper tip 71 passing therethrough, and the latter half side is attached to the outside of the left side plate 21. A release lever 73 for releasing the locking state of the locking stopper 7 is attached to the portion attached to the outside. When the release lever 73 is rotated around the axis, the entire locking stopper 7 is rotated. The stopper 71 is retracted toward the outside of the left side plate 21 so that the stopper tip 71 comes out of the locking hole 72 a of the stopper receiver 72.

  At the rear end side of the locking stopper 7, the end of the cylinder fixed to the nut that fixes the locking stopper 7 to the left side plate 21 so that the entire locking stopper 7 moves backward when the release lever 73 is turned around the axis. A cylindrical release lever guide 74 whose portion is formed obliquely is attached. When the release lever 73 is rotated about its axis by the release lever guide 74, the entire locking stopper 7 is moved rearward along an end portion formed obliquely.

Next, a method for using the supine cervical tractor based on the configuration of the best mode for carrying out the above device will be described below.
The slide plate 5 pulled toward the front side of the machine frame 2 by the spiral spring 6 is pushed back toward the rear side and locked at a predetermined position. When the slide plate 5 is pulled back with a force stronger than the spring force of the spiral spring 6, the slide plate 5 moves to the rear plate 24 side of the machine frame 2 and is locked to the guide inclined side surface 72 c of the stopper receiver 72 connected to the slide plate 5 that moves. The stopper tip 71 of the stopper 7 starts to contact.

  The stopper tip 71 that abuts is gradually retracted along the guiding inclined side surface 72c that gradually protrudes toward the left side plate 21, and is then relatively moved along the side surface of the locking hole 72a in which the locking hole 72a is formed. After the movement, the engagement hole 72a is entered by the spring force (not shown).

  When the stopper tip 71 of the locking stopper 7 enters the locking hole 72 a on the side surface of the stopper receiver 72, the slide plate 5 that is always pulled by the spiral spring 6 is locked at its predetermined position, and is released by the release lever 73. It will not move unless the locked state is released.

  After the slide plate 5 is locked at a predetermined position, a pillow a is placed on the slide plate 5. The pillow a is fixed to the surface of the slide plate 5 by a hook-and-loop fastener 51 attached to the surface of the slide plate 5. Is done. The head is placed on the pillow a of the slide plate 5 with the neck placed on the lower side of the tilted slide plate 5 and lying on its back.

  When the release lever 73 is turned by hand, the entire locking stopper 7 moves backward toward the outside of the left side plate 21, and the stopper tip 71 of the locking stopper 7 comes out of the locking hole 72 a of the stopper receiver 72 and comes off. . When the stopper tip 71 of the locking stopper 7 is disengaged from the locking hole 72 a, the slide plate 5 is pulled by the spring force of the spiral spring 6, and the head placed on the slide plate 5 also moves together with the slide plate 5. As a result, the cervical spine can be stretched, and by stretching the cervical spine, nerve compression is relieved to relieve numbness, stiff shoulders, etc., and a therapeutic effect by cervical traction can be expected.

  The present invention is not limited to the best mode for carrying out the above-described invention, and various modifications can be made without departing from the spirit of the present invention.
