Description

Swing recovery traction bed

technical field

The invention relates to a traction bed, which is a spinal traction bed capable of swing recovery, and is used for treating lumbar diseases with symptoms such as lumbar intervertebral disc herniation.

Background technique

Traction therapy is a method of applying the relationship between action force and reaction force in mechanics to achieve the purpose of treating spinal diseases through special traction devices. The equipment used in traction therapy is a traction bed. Ordinary traction beds mainly include a bed frame, a bed surface, and a traction device. During traction, under the action of the traction device, the straps of the patient's upper body and lower body move in opposite directions, causing the patient's waist to produce tension. A certain tension can achieve the purpose of traction therapy.

At present, most of the traction beds on the market can only achieve longitudinal stretching treatment of patients, but cannot achieve a horizontal rocking movement. Very few traction beds that can achieve multiple movements are difficult to apply due to their complex structure and high price. The vast number of small and medium hospitals and family rehabilitation.

Detailed ways:

The present invention will be further explained below in conjunction with the accompanying drawings.

As shown in Figures 1 to 8, the swing recovery traction bed of the present invention includes a bed frame 1, a bed surface and a traction device.

The bed surface comprises a bed board 3 arranged on the top of the bed frame 1, an upper body fixing plate 5 is arranged on the upper half of the bed board 3, and an arc track and an arc groove 18 are arranged in parallel on the lower half of the bed board 3 along the transverse direction. In order to ensure the guiding accuracy and have a large bearing capacity to withstand the weight of the patient's lower body, the arc track is a combined guide rail composed of a triangular guide rail 8 and a rectangular guide rail 6 . The lower body fixed plate 7 is set on the arc track, the lower body fixed plate 7 is flush with the upper body fixed plate 5 surfaces, the lower body traction box 10 is set on both sides of the lower body fixed plate 7 afterbody, the lower body traction box 10 and the lower body fixed plate 7 pass through the draw-in groove 20 connects, is convenient to dismantling, and lower body traction box 10 offers lower body traction belt hole 22, and lower body traction belt bolt 9 is set in the lower body traction box 10, and lower body traction belt bolt 9 lower ends are screwed into threaded hole 21 at draw-in groove 20 bottoms. Upper body fixed plate 5 afterbody is provided with arc-shaped end, and lower body fixed plate 7 heads are provided with the arc groove that matches with arc-shaped end, and lower body fixed plate 7 afterbody is tapered, and taper angle is 40 °, can reduce like this The lower body fixing plate 7 swings and takes up space, and at the same time, it is convenient to launch the lower body traction box 10 with a certain inclination. In order to make the stretching force height better adapt to the thickness of the human body, a bedside hole 17 is provided at the head of the bed board 3, upper body traction belt holes 16 are provided on both sides of the bedside hole 17, and the lower end of the T-shaped support 4 stretches into the bedside In the hole 17, the T-shaped support 4 can adjust the height up and down.

Traction device comprises upper body traction motor 2 and motor and deceleration mechanism 9, upper body traction motor 2 is arranged in the bedside box of bedstead 1 head, and motor and deceleration mechanism 9 are arranged on the motor support plate 12 of bedstead 1 bottom. Motor and deceleration mechanism 9 are connected with one end of crank 15, and the other end of crank 15 is provided with slide block 14 with hole, and slide block 14 with hole is set on the long rocker 13, and long rocker 13 one end passes through arc groove 18 and The lower body fixed plate 7 links to each other, and the other end of the long rocking bar 13 links to each other with the bed board 3 through the long rocking bar fixing hole 19 . The long rocker 13 is formed by two sections connected by threads, so that the slide block with holes 14 is installed on the long rocker 13 to facilitate, while ensuring that the connecting point is far away from the limit position of the slide block with holes 14 . The crank 15 is driven to rotate by the motor and the reduction mechanism 9, and the slider 14 with holes slides on the long rocker 13 driven by the crank 15, driving the long rocker 13 to swing back and forth, and the lower body fixing plate 7 is driven by the long rocker 13 Swing back and forth along the arc track on the bed board 3. The crank 15 is a telescopic crank, and the farthest deviation point of the long rocking bar 13 from the center line of the traction bed is controlled by controlling the length of the crank 15, thereby adjusting the swing angle of the lower body fixing plate 7.

When performing treatment, the upper body fixing sleeve and the lower body fixing sleeve are respectively fixed on the patient's upper body and lower body, the lower body fixing sleeve is connected with one end of the lower body traction belt, and the lower body traction belt other end is passed through the lower body traction belt hole 22 into the lower body traction box 10 Inside, and be fixed on the lower body traction belt bolt 9, the upper body fixed cover links to each other with the upper body traction belt one end, and the upper body traction belt other end walks around the T-shaped support 4 earlier, passes the upper body traction belt hole 16 and links to each other with the upper body traction motor 2 then. The traction motor 2 of the upper body is controlled by a microcomputer, and longitudinally tracts the patient's spine through the traction belt of the upper body. During the longitudinal traction of the spine, the patient's lower body swings periodically horizontally with the lower body fixing plate 7, which changes the muscles, ligaments, fascia, and joints of the spine. Capsular soft tissue, correct deformed spine, help restore natural shape.

The above is only a preferred embodiment of the present invention, it should be pointed out that, for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications can also be made. It should be regarded as the protection scope of the present invention.
