Description

Apparatus for cervical rehabilitation.

Object of the invention

The invention relates to a specific apparatus of gymnastics to strengthen neck muscles due to lesions or osteoarthritis of the cervical vertebrae.

Background of the invention

There are currently very few devices specific for the rehabilitation of cervical lesions, being known mostly those of draft or traction, not being suitable for cervical bodybuilding. This type of equipment electric drive have the drawback that the movement performed by the patient is not gradual but passes sharply of a resistance force determined to zero kilos, which causes inconvenience to users. It also lacks a traction regulation system appropriate to each patient and concrete treatment

Another type of similar device, also of Electric drive also acts by cervical traction, which allows the user to hang up and off-hook in a limited way exerting a certain vertical force through a band applied to the patient's lower jaw, at whose ends a rope linked to a pulley system is fixed motorized

These types of devices are usually quite expensive and bulky, they require a specific electrical installation with its adequate protections, with the disadvantage of the risk that it also involves the risk of interruption of the energy supply electric when they are being used. For these reasons, normally only rehabilitation institutes have them.

The author of the present invention has created a new type of device that solves the exposed problems, whose main characteristics are described below.

Description of the invention

This cervical rehabilitation device is composed of an articulated or fixed frame, with regulation of height, fixed to the wall by a support. This device is manufactures in two versions, as for personal use, multifamily or for rehabilitation clinics.

The version with articulated frame has a height-adjustable support composed of a sheet folded in its two extremes forming two angles at 90º. These angles hold two parallel vertical bars through which the guides slide frame female, whose position is regulated by knobs threaded, to facilitate its use to patients of different height.

The fixed frame version is designed preferably for use at the patient's home. Have a support of any geometric figure which is fixed to the wall and has a rectangular section slot through which introduce the fixed frame, adjusting its height by a knob similar to the previous version.

Both racks are arranged at the opposite end to the mentioned supports of a threaded hole in which it is screwed a tube. This tube has two male threads, one fixed to the frame and the other to a force regulator and support guide of the axis. Said tube serves as a guide and support for a metal shaft of circular section, which slides axially.

At one end of this axis is a base of support of the user's head, which when pressing on it exerts force on a coaxial spring with the shaft. The career of axis, and therefore the force exerted by the user, is limited by force regulator whose position is previously selected depending on the therapeutic treatment prescribed by the doctor and of Your progress in patient recovery. Force regulator It has seven positions: 1, 2, 3, 4, 5, 6 and 7 Kg. Its position it is fixed according to the scale of forces, screwing or unscrewing said regulator. Each turn of the regulator equals 0.25 kg

This force regulator is a tubular knob threaded, which has a force limiter consisting of a ball, a spring, a pressure screw of said spring and a bushing inside guide of a circular metal shaft that slides axially

When the user makes strength with his head pushing the support base, perceives the arrival at the position of the default force limiter because when the shaft slides on its guide, its circular groove or similar fits into the ball of the limiter. This force limiter can be mechanical like the described or also acoustic, bright, vibrating, etc.

To prevent the device shaft from rotating on itself It also has another longitudinal groove, within which protruding the end of a bolt screwed into the tube screwed.

This device, of small dimensions, can use any person and it is simply mounted with studs and screws to a wall. The version with articulated frame occupies very little space, since when it is not used it can be folded turning it 90º upwards on the frame bolts.

The version with fixed frame is disassembled easily loosening the height adjustment knob, which allows to remove it so that it does not take up space.

Preferred Embodiment of the Invention

Among the different types of devices for cervical rehabilitation that can be manufactured based on This invention, the preferred embodiment is as described in continuation:

Based on the type of exercises you should perform a user (19), the necessary force, the area of the body to rehabilitate, that is cheap and small in size, easy to install and use, the inventor of this rehabilitation device cervical (1) thought about the following solution:

The device basically consists of a support (5) which is fixed to the wall (16) with dowels and screws (16.1), composed by a metal sheet with an upper angle (5.1) and angle bottom (5.2), two parallel vertical bars (5.3), two guides (5.4) female, two knobs (17) for height adjustment of the frame (7) that is shaped like a (U), secured by two screws (7.3) to the arms (6).

These two height adjustment knobs (17), each have a screw threaded into the guide (5.4), in which end there is a plug (5.5) of thermoplastic material which is the intermediate element between the screw of each knob and the bar (5.3)

       \ global \ parskip1.000000 \ baselineskip
    

The frame (7) can rotate 90º upwards articulated in the screws (7.3), in order that the device (1) Take up as little space as possible when not in use. When is in working position, the turn limit is determined by the two stops (7.2) that rest on the arms (6), also fixing its position by anchoring the frame (7.4) composed of the Classic stud / spring / ball system and housing.

This frame (7) has at the base of the "U" of a hole where the tube (9) that has been threaded of a male thread (9.1), of a bolt (9.2), of a guide bushing (3) and of a locknut (11). Inside this guide bushing (3) the shaft (2) slides, which has a circular groove (2.1), a longitudinal groove (2.2), and a threaded end (2.3). At this end (2.3) the support base (15) is threaded by the plate (15.1) fixed thereto and the locknut (14). This base Support (15) is rubber.

Between the frame locknut (11) and the base locknut (14), there is a force spring (13) wrapped by the flexible sleeve (12).

The function of the longitudinal groove (2.2) is the to prevent the shaft (2) from rotating; said turn is limited by the free end of the bolt (9.2) screwed into the tube (9).

The male thread (9.1) is mounted on force regulator (8) that when turned on the tube (9) determines its position based on the force that the user (19) wish. This force is marked on the force scale (10).

By turning the regulator (8), what is done is shift the position of the force limiter (4) consisting of a screw (4.1), a spring (4.2), a ball (4.3) pressed by said spring (4.2) on the shaft (2) and an inner bushing that serves as guide.

When the user (19) pushes the support base (15) there comes a time when the circular groove (2.1) is fitted with the ball (4.3); at that moment he perceives that he has reached the position of force preset on the scale (10) but obviously if the user (19) continues to be strong this could be exceeded limit.

While in this preferred embodiment the limiter is fully mechanical, it could also be another type of limit switch or position detector or acoustic sensor, bright, vibrating etc.

The tube (9) is displaced down 15 mm with respect to the plane of the frame (7), to prevent it turn up when it is being used. In this way the moment of forces always tends to turn the frame down (7), which is limited by the stops (7.2).

Once nature is sufficiently described of this invention, as well as a practical application thereof, it only remains to add that both its shape and the materials and manufacturing procedure, are subject to modifications, provided that they do not substantially affect the characteristics which are claimed below.
