Description

The utility model relates to medicine, specifically to mechanotherapy, and is intended to strengthen the muscles of the lower extremities and develop movements in the process of rehabilitation of patients after injuries, hip fractures and diseases of the hip joint.

The closest is a device for restoring the function of the lower extremities (RF patent No. 2352316, IPC A61H 1/02 (2006.01), publ. 04/20/2009), containing a base equipped with additional engines, carriages with devices for fixing the limbs, connected through traction with electric motors whose motors are connected to the control system. Moreover, popliteal rollers are fixed on the shafts of these engines through the lever. Electric motors are equipped with carriage position sensors, and each of the carriages is equipped with two racks, in the upper part of which hinges are fixed, connected through brackets with stops for feet.

However, the device for restoring the function of the lower extremities is not able, with the help of passive movements that correspond to normal walking parameters, to stretch tense and shortened muscles, tendons and ligaments of the hip joint along all its motion vectors and is unable to restore the functional length of muscles and ligaments, as well as mobility joint in full.

The purpose of the utility model is to restore and ensure full motor volume in the hip joint along all possible motion vectors: adduction, abduction, flexion, extension, rotation and other possible vectors.

This goal is achieved by the fact that the apparatus for rehabilitation after injuries, hip fractures and diseases of the hip joint, comprising a body, an electronic control unit, a foot stand, powered by an electric motor, the electric motor is equipped with a mechanism that converts rotational movements into low-amplitude horizontal-translational, proximal distal and rotational low-amplitude oscillatory movements. On the base of the apparatus, a compressor is installed, connected to a pneumatic compression-vibration massage femoral cuff, in which a vibroelement is mounted.

Pneumocompression-vibration massage femur cuff provides vibration compression massage on the thigh tissue during their passive low-amplitude stretching and rotational gymnastics, carried out due to the movements of the footrest.

An electric motor with a mechanism that converts its rotational movements into low-amplitude horizontal-translational, returnable and rotational low-amplitude vibrational movements of the footrest with an approximate frequency of 100 movements per minute. All this leads to increased extensibility and elasticity of the musculo-ligamentous apparatus of the thigh and hip joint, as well as increased metabolic processes in muscle tissue, lymphatic drainage and relaxation tensile effect. The presence of a rotational component also leads to an increase in metabolic and regenerative processes in damaged tissues, in addition, a change in the consistency of tissues, an increase in their elasticity leads to increased optimization of blood circulation and metabolic processes.

The utility model (Fig. 1) consists of a housing 1, mounted on a base 2, on which an electric motor 3 is mounted, connected to a footrest 4, by means of a mechanism 5, which converts the rotational movement of the electric motor into low-amplitude horizontal translational proximal distal and rotational low-amplitude oscillatory movements. A compressor 6 installed on the basis of a utility model is connected via a pneumatic hose 7 to a pneumatic compression-vibration femoral cuff 8 equipped with a vibration element 9. The utility model includes an electronic control unit 10, a power supply 11, and a control panel 12.

The utility model works as follows.

The patient is placed on the thigh with a compression-vibration femoral cuff 8 and a foot is placed on the stand 4. The remote control 12 turns on the device through the electronic control unit 10 and the power supply 11. The electric motor 3 starts to work. The mechanism 5 converts the rotational movements of the electric motor 3 into low-amplitude horizontally translational, proximal distal and rotational low-amplitude oscillatory movements of the footrest 4. At the same time, the compressor 6 installed on the base 2 starts to work, it inflates the pneumocompression-vibration massage cuff 8 through the air hose 7, and starts vibration element 9, which produces vibration massage, works, they relieve unpleasant pain, cause relaxation of muscles, tendons, ligaments. Increase the outflow of waste fluids from damaged tissues. The control panel 12 and the electronic control unit 11 allow you to include various modes of operation of the mechanism 5, supports for legs 4, compressor 6 and vibration element 9.

There are several methods of working with this unit, we will describe some of them.

1. The methodology aimed at eliminating the post-traumatic functional shortening of the muscles leading to the thigh (figure 2). Elimination of post-traumatic hip contracture along the hip abduction vector.

Starting position of the patient: the legs are spaced as wide as possible, wider than the shoulders, until the appearance of prestressing of the tissues of the hip and hip joint. The damaged thigh is in a state of maximum abduction, the device is on the side of the patient from the side of the sore leg. Before the patient there is a stable support, on which he rests with his hands, moving the body weight to his hands. (Support in the form of a high couch) Thus, the minimum load is placed on the hip joint and leg. The patient can lean his body on the couch - support, reducing the load on his legs and hips to a minimum.

The foot of the injured leg is installed on the center of the footrest, the leg is maximally straightened in the knee joint, the joint is turned off from movement. A pneumocompression-vibration massage cuff is put on the thigh of the restored limb.

The device begins to operate. A vibro-massage-compression effect is exerted on the tissue of the injured thigh during passive gymnastics performed by the apparatus, and specifically during committed passive low-amplitude adduction-abduction tensile oscillatory movements of the thigh and passive low-amplitude rotational movements in the limb and thigh. This passive, intensive gymnastics (100 movements per minute) forcibly removes the barrier to limiting functional contracture, since with this passive gymnastics the musculo-ligamentous apparatus of the hip joint and hip are relaxed as much as possible, which means that the movement of the articular surfaces and stretching of the musculo-ligamentous apparatus of the joint are more effective several times than with any other types of exposure. In addition, the effect is also due to a large number of passive driving-diverting low-amplitude and rotational low-amplitude movements per unit time, which is ensured by the operation of the apparatus. But during this intensive gymnastics, the tissue of the joint and thigh under development: muscles, ligaments, fascia, tendons, are in a state of increased tension. They have post-traumatic shortening, rigidity. Therefore, the patient with passive and intense rotational vibrational tension experiences discomfort and unpleasant minor pain. These uncomfortable phenomena and problems with rigid tissues of the thigh are removed by pneumocompression-vibration massage femoral cuff. The performed vibration-compression massage performs a kneading, vibrational compression massage effect, as a result of which tissue extensibility and lymphatic drainage of damaged tissues are enhanced.

2. In the case of eliminating contracture of the hip joint along the hip extension and flexion vector, eliminating the shortening and overstrain of muscles and ligaments that extend the hip (Fig. 3), exercises on the apparatus are performed as follows.

The patient is facing the apparatus, on two sides of it are two fulcrum in the form of couches. The patient leg, straightened, turned off in the knee joint, the patient puts on the center of the footrest.

The patient, leaning on the couch-supports with his hands, transfers the heaviness of the body to his arms as much as possible, unloading his legs. The diseased leg, straightened in the knee as much as possible, turned off in the knee joint, is set forward to prestress the tissues of the thigh and hip joint. The foot of the sore foot is placed on the center of the footrest. A healthy leg is pushed back as much as possible, also to the prestressing of tissues. A pneumatic compression and vibration femoral cuff is put on the hip, then passive intense low-amplitude stretching tissue gymnastics is performed, as a result of which the patient’s diseased leg performs low-amplitude flexion-extension movements in the thigh at the level of tissue prestressing, removing the barrier of motor restriction, with a rotational low-amplitude vibrational effect these movements carry out pneumatic compression-vibromassage effect on the tissues of the damaged thigh, th causes eliminate contractures and above listed therapeutic effects.

3. If it is necessary to stretch the musculo-ligamentous apparatus, which leads the patient’s legs away (Fig. 4), the legs are crossed as much as possible before prestressing in the tissues being worked out and the diseased leg rests on the outside of the foot on a footrest. Further effects of the apparatus are described above.

Thus, the apparatus we offer is capable of performing passive gymnastics and gymnastics with relief, practically, along all axes of movement of the hip and hip joint, aimed at stretching, relaxing the musculoskeletal apparatus of the thigh and hip joint. With it, it is possible to restore movements in the hip joint and hip along all motion vectors and in full, quickly and effectively eliminate post-traumatic hip joint contracture and contracture of a different genesis.

The proposed utility model allows to reduce the rehabilitation time and restore the functions of the lower extremities to a fuller extent. In addition, the proposed device is not difficult to maintain and operate, and therefore can be used on the basis of any hospital and in outpatient treatment.
