Abstract

A cervical vertebra rehabilitation apparatus comprises a cylinder body, a spring arranged in the cylinder body, a piston rod arranged in the cylinder body and on top of the spring, a pillow rest on the top of the piston rod and a brace that is provided with a handle and connected to both sides of the cylinder body, which is characterized in that a T-shaped bracket arranged horizontally and extended ahead is connected to the bottom of the cylinder body and the rail on the front end of the T-shaped bracket is circularly arc; a guide mechanism is arranged in matching relationship between the piston and the inner wall of the cylinder boy. The utility model is characterized in that the structure becomes more reasonable and the operation becomes smoother with comfortableness. The T-shaped bracket added to the prior art can ensure that the conductive force line sent by the pillow rest to a connecting rod, the piston and the spring is in the direction same as the motion direction of the head neck in the process of exercise, good for smooth functional exercises; the shape of the pillow rest is changed to be more matched with the neck curve for comfort; the guide slide way designed between the piston and the cylinder body ensures the pillow rest not to rotate in the process of exercise.

Description

Cervical back muscle trainer

Technical field

The utility model relates to a kind of medical rehabilitation apparatus, relates to a kind of cervical back muscle trainer specifically.

Background technology

In the epoch of social develop rapidly, the quickening of gathering owing to life joint, the increase of work and study pressure, long-term overtime low first-class reason cause the present cervical spondylopathy incidence of disease to improve year by year, and the trend of rejuvenation are arranged.

The biomethanics balance of cervical vertebra meets load distribution rule.Cervical vertebra rear portion muscle has the supporting role of dominance.Because the special posture before the physiological of cervical vertebra in song and the life and work, compression is often born in the cervical vertebra front portion, and stretching stress is often born at the rear portion.Continue excessive stretching meeting and cause rear portion muscle chronic strain; Injure operation outward and wait acute the weakening that can cause rear portion muscle muscular strength; The disuse atrophy of rear portion muscle can take place in the long-term cervical vertebra braking in operation back; Acute and chronic injury can make all that capsular ligament is torn, ligament fatigue.In above-mentioned factor, muscle belongs to the ACTIVE CONTROL dynamical system, and capsular ligament and ligament then belong to passive limiting factor.The stretching and sorting of their fellowship FSUs.But the cervical vertebra shakiness takes place in the then hypofunction of secondary cervical vertebra rear portion supporting structure behind the acute and chronic injury, increases the weight of generation and development that interverbebral disc and bone joint degeneration also cause each myelopathy thus.

At present the cervical vertebra functional training method that generally adopts is that both hands intersect to place and stretch that motion is confronted with each other after occipitalia and the Head and Neck or health is stretched crown wall after leaning on the top of a wall neck.The domestic special equipment report that yet there are no relevant cervical vertebra functional training.Abroad, Dreisinger, the cervical vertebra extensor of the back functional training apparatus that people such as TE have carried out healthy premenopausal volunteers is used the comparative study of above-mentioned outmoded functional training method with the cervical spondylopathy patient, think that its easy cervical vertebra extensor of the back functional training apparatus can obviously improve cervical vertebra extensor of the back power, but its apparatus also is not applied to the cervical spondylopathy patient.

Present patent application inventor is once in Chinese patent of application in 01 year, authorize, name is called: a dorsal muscles functional training rehabilitation device (patent No.: ZL 01 2 39641.9), it forms (structure as shown in Figure 4) by pillow holder, connecting rod, piston, cylinder, spring, braces, handle etc.During use, the rehabilitation device is placed the cervical vertebra rear, the pillow holder places the outer knuckle of pillow bottom, make shoulder belt sagging to the front by shoulder, two handles link to each other with shoulder belt, and both hands are held the downward tractive of handle, neck is stretched the roof pressure neck brace to layback, strength acts on spring by connecting rod, and the reaction force acts of spring makes the item dorsal muscles at cervical vertebra rear portion obtain taking exercise in occipitalia simultaneously.

But this dorsal muscles functional training rehabilitation device finds to have following deficiency in concrete the use: the profile of pillow holder not too is fit to the profile of occipitalia; The strength conduction orientation in the exercise and the direction of cervical vertebra activity are inconsistent; Owing to there is not counter rotation device, the pillow holder rotates easily in the exercise process.

Summary of the invention

That a kind of structure that the purpose of this utility model designs at existing weak point in the above-mentioned prior art just more becomes rationally, uses is more comfortable, cervical back muscle trainer smoothly.

The purpose of this utility model realizes by following scheme: this cervical back muscle trainer comprises cylindrical shell, be seated in the spring in the cylindrical shell, be installed in the cylindrical shell and be positioned at the piston rod of spring top, be positioned at the pillow holder of piston rod part, and be connected the cylindrical shell both sides and have the band of helping to shoulder heavy thing of handle, wherein: be connected with one in the cylindrical shell bottom and extend the T shape support that is horizontal positioned forward, and the cross bar of T shape support front end is circular arc; Between piston and cylinder inboard wall, be provided with the guiding mechanism that cooperatively interacts.

In the utility model, T shape rack cross-bar front end face is 30 ° the inclined-plane of being inclined upwardly, and can steadily contact with back part, prevents skin generation roof pressure; The extension elongation of the support bar of T shape support can be adjusted by its fixture in the cylindrical shell bottom, and purpose is to be convenient to adapt to different line of actions.The pillow holder is the ingot-shaped of symmetry all around, its upper surface is a downward arcuation concave surface, front upper side face and back upper side all be consistent with the profile of the pillow neck of human body to circular-arc of lower recess, this pillow holder improves on original basis, the profile of pillow holder is consistent with the occipitalia profile of human body, makes the people more comfortable in cervical vertebra functional training process.For the pillow holder is not rotated, with piston bilateral symmetry design that the pillow holder is fixedlyed connected by piston rod guide chute is being arranged, be symmetrically arranged with the guide rail that matches with this guide chute at the inwall of cylindrical shell.

The purpose of design of this cervical back muscle trainer just is to strengthen cervical vertebra rear portion muscle strength by functional training, alleviate dmm, balance cervical vertebra muscular strength, thus reach the purpose of eliminating cervical vertebra ache, enhancing cervical stability, anti-treating cervical spondylosis, and can be used for the exercise of cervical spondylopathy postoperative function.

Characteristics of the present utility model are: this cervical back muscle trainer is owing to increased T shape support on the basis of existing technology, can make in the exercise process pillow holder consistent with the direction of motion of Head and Neck, help carrying out smoothly of functional training to the conduction line of force of connecting rod, piston, spring; And improved the shape of pillow holder, pincushion and neck curve are mated more, more comfortable during use; And between piston and cylindrical shell the shaping-orientation chute, guarantee that in the exercise process pillow holder does not rotate.
