Description

The invention relates to medicine and can be used for the treatment and rehabilitation of patients suffering from pathologies leading to partial immobility, impaired ability to maintain balance, for patients with muscle atrophy, contractures, cardiovascular diseases, complete or partial absence of one of the lower extremities, and as well as general healing of the human body. It is applicable in cases of the presence of cerebral palsy in patients, the back of a bifid, suffering from a disproportionate weight in relation to growth, the absence of limbs that have been amputated, and other diseases. Treatment and rehabilitation are carried out by the patient receiving physical activity, which makes the vestibular apparatus, musculoskeletal system, muscle system of the legs, abdomen and back, the cardiovascular and respiratory systems work, creates a load on the bone skeleton, improves metabolism, etc. Presented therapeutic runbike is a means of movement, driven by the muscular strength of the legs of the patient. Any reasonable load contributes to recovery and improvement of the body. Active exercises as the treatment of various diseases were invented long before the awareness of the properties of physiotherapy exercises.

For people with disabilities, movement is extremely important; it also supports the overall tone of the body.

Various types of bicycles and runbikes are known. In US Pat. No. 4,798,395, a patient is located between the rear wheels of a therapeutic bicycle. However, the design is very cumbersome and inconvenient to control, place the patient on it, as well as storage. In the designs of exercise bikes Veloider, https://dcp-velo.ru/ and Angel Solo, http://www.angelsolo.ru/catalog/rehabilitation_bikes/, there are also a large number of disadvantages. Here is some of them:

- according to manufacturers, the range of users is limited to people suffering from cerebral palsy

- the patient needs to be raised to sit on an exercise bike, which is particularly inconvenient if it is large. This is very felt if the patient weighs, for example, 50-80 kg or more.

- there is no adjustment of lateral stability of the exercise bike, and as a result, safe movement is possible only on a flat surface.

- these exercise bikes have a very large dynamic mass and large weight, and this requires the application of tremendous forces both on the part of the patient, which he usually does not have, to move the whole structure together with its own weight, and on the part of people who owe it push or bring home.

- Large dimensions create inconvenience in use, everyday life, taking the product out to the street and storing it at home.

- limited number of settings for individual patient characteristics

- High and not adjustable Center of Gravity.

- inconvenient to manage.

- difficult to disassemble / assemble.

- there is no damper on the steering column, and as a result, poor control of the rotation of the front wheel.

The closest to the proposed technical solution is the PETRA racerunner design described in advertising booklets and on the manufacturer's website https://by-conniehansen.com/.

The design consists of a frame on which three wheels are mounted, one of which is equipped with a steering wheel, there is a seat and support for the patient's chest. The design is also equipped with a brake. The patient's seat is located near the rear axles of the three-wheeled vehicle or even above the specified axis. As our studies have shown, the weight distribution for each of the wheels of this design with a patient weight of 88 kg is: front wheel - 18 kg, each of the rear wheels - 36 kg, taking into account the weight of the vehicle itself 16 kg. Obviously, this circumstance is fraught with the rider rolling over backwards under any disturbances or obstacles in front of the front or even in front of the rear wheels. Since when raising the front wheel even by 5-10 cm relative to the rear wheels, or when receiving the impulse by the front wheel when hitting an obstacle and tilting the entire structure back, the bulk of the patient’s body weight is also transferred backward, going beyond the axis of the rear wheels and causing it to tip over. It should also take into account the overturning moment, aimed at tipping the vehicle back and acquired by the vehicle from the feet of the patient himself, pushing off the ground and. This can lead to personal injury. The danger of tipping over is also confirmed by the manufacturer itself, warning signs about the possibility of tipping over are applied on one of the racks of their bicycles. There is no possibility of adjusting lateral stability, changing geometry, or other adjustments that increase both the area of application, the safety of using the bicycle, and the settings for the individual patient's characteristics.

The proposed design is based on the fact that the saddle, perceiving the main weight of the rider, should be located in the center of gravity of the triangle formed by the points of contact of the wheels of the therapeutic runbike with the ground or be slightly offset back from the center of gravity along the axis of symmetry of the vehicle. The construct of the runbike itself should allow changing its geometry in order to select the optimal location of the center of gravity (Ts.T.) and the center of mass of the entire structure, possessing the maximum number of settings and adjustments that allow not only expanding the audience of users, but also guaranteeing their safety as much as possible.

The technical problem to be solved was the need to create a runbike providing treatment and rehabilitation of the vestibular apparatus, musculoskeletal system, strengthening the skeleton and muscles, improving the work of the cardiovascular system, respiratory functions, cerebral palsy, bifid back, autism, metabolic activity of the body, etc. creating an active load with the maximum number of settings for the individual characteristics of the patient, as well as guaranteeing safety for the patient user m The proposed therapeutic runbike can be used both outdoors, in parks, for driving on the highway and on rough surfaces, and can be used indoors.

The technical result of the invention is to ensure that the maximum number of settings for the individual characteristics of the patient.

The essence of the invention is expressed in the aggregate of essential features in which the therapeutic runbike for treatment and rehabilitation is set in motion by pushing the patient off the ground with the feet, including a front wheel fork equipped with a steering wheel, fasteners, front wheel and front wheel brake, a supporting tube with rear wheels mounted on it , rear wheel brakes, a frame consisting of a connecting pipe equipped with a chest stop and connecting the upper pipe to the support pipe, from the steering cup equipped with bearings s, fasteners and bushings, as well as an upper pipe equipped with a seat tube with an adjustable saddle, fasteners in which the docking and supporting pipes are made for disassembly, mutual movement and are equipped with a connecting element containing fasteners and clamps, the supporting pipe itself is additionally equipped with connecting elements equipped with clamping fasteners and clamps, equipped with the ability to move both along and rotate around the axis of the supporting pipe, and in which quick-disconnect bushings are mounted the axles of the rear wheels in them, as well as the chest support adjustable in height and angular position, while the patient is equipped with the opportunity to approach the saddle of the therapeutic runbike between the rear wheels.

In special cases of its implementation or use, the therapeutic runbike may contain telescopic support and docking tubes, a composite support tube, a front wheel fork equipped with a steering angle limiter, a patient support belt adjustable in length and equipped with elastic elements, a chest support equipped with soft linings and having an anatomical a shape, adjustable in length and equipped with elastic elements, a belt for hanging one of the patient's lower extremities above the ground, crosspiece w connecting the ends of the carrier pipe, steering damper connecting the front wheel fork to the upper pipe, one of the wheels having the possibility of one-sided rotation, seat tube equipped with a support for the back, height, horizontal and angular position, while the support for the back itself has an anatomical shape, equipped with soft pads, adjustable length belt and equipped with elastic patient fixation elements.

The therapeutic runbike for the treatment and rehabilitation of people with disabilities comprises a front wheel 1 mounted on a fork of the front wheel 2 installed in the steering glass 3. The steering wheel 4 is mounted on the fork 2 and the steering damper 16 is connected to the upper pipe 5. The upper pipe is equipped with a clip 8 and fasteners 9 for fixing the seat tube 10 on which the seat 11 is mounted. The connecting pipe 6 connected to the upper pipe 5 contains a connecting element 14 equipped with fasteners and clips 18 and 19 of FIG. 4., and corresponding holes 17 and 21. The connecting element 14 can move up and down along the docking pipe 6, and, therefore, the carrier pipe 12 changes its position relative to the horizontal. Due to this, the base of the therapeutic runbike lengthens or shortens, the position of the center of gravity and the center of mass changes. In FIG. 1, these movements are shown by arrows and the angle “C” is indicated. Another connecting element 14 is installed on the supporting tube 12, which comprises a thrust for the chest 13, which has the ability to move along the height of FIG. 1, FIG. 2 and FIG. 3, longitudinal along and rotating about the axis of the supporting pipe 12 of FIG. 2, which became possible due to the use of the element 14. At the ends of the carrier pipe, connecting elements 14 are also installed, by means of which the rear wheels 15 of FIG. 1. The damper of the steering wheel 16 is necessary to exclude sharp turns of the front wheel and ensure the stability of the direction of movement. This phenomenon may occur due to the physiological characteristics of patients. On the steering wheel 4 can be mounted adjustable along the length of the straps fixing the position of the hands, equipped with elastic elements. The figures are not shown.

In this design, the projection of the clamp axis 8 of the seat tube 10 falls to the height of the triangle formed on the plane by the points of contact with the ground of the wheels of the therapeutic bicycle, and is as close to the center of gravity of the isosceles triangle itself. This allows you to maximize bring the main weight of the rider to the center of gravity and the center of mass of the entire structure of the runbike.

Adjustment of the saddle 11 is carried out in height and longitudinal direction by means of a seat tube 10.

The contact points of the wheels 15 with the earth form a triangle. The movement of the rear wheels 15 along the axis of the supporting pipe 12 is carried out by using connecting elements 14, as a result of which the geometric dimensions of both the therapeutic runbike and the triangle are changed, which also allows you to adjust the position of the center of gravity and the center of mass of the whole structure. Rotating the connecting element 14 around the axis of the carrier pipe 12 of FIG. 3, the angular position of the wheels 15 relative to the horizon changes, which allows you to adjust the lateral stability of the therapeutic runbike.

The patient support belt, adjustable in length and equipped with elastic elements 24 of FIG. 2 can be attached to the supporting tube 12, or to the support for the chest 13. If necessary, the simultaneous use of two such belts. The same belt as described in pos. 24 is used to hang one of the patient's lower limbs. It is also attached to the horizontal part of the supporting tube 12. This is especially convenient for patients with artificial prostheses, pushing from the ground with a healthy foot occurs in more comfortable conditions. All this has proven itself in the work, creating both a greater number of adjustments and increasing safety conditions for a certain category of patients. Due to the fact that the steering glass, front wheel fork, bearings, fasteners, brakes are well-known standard products for bicycles and runbikes, they were not displayed in the figures. The rear wheel brakes borrowed from wheelchairs are installed on the inclined parts of the carrier pipe. They are also not shown in the figures.

The principle of operation of the connecting element 14 of FIG. 4 is described in detail in patent No. 187938 and is shown by the example of the joint of the docking pipe 6 and the supporting pipe 12. The clamping is performed by the fasteners 18, and the rotation is prevented by the latch 19, which is illustrated in FIG. 5. The connecting element provides the possibility of both quick dismantling / installation of the therapeutic runbike and the reliability of the connection of its forming parts.

The articulation of the quick coupler 7 on the axis 20 of the wheel 15 is shown in FIG. 6. Having released the fasteners 18, the quick-detachable sleeve 7 is released, which is fixed on the axis of the wheel, and, accordingly, it is possible to quickly remove the wheel 15 from the runner. Having released the fasteners 18, you can rotate the connecting element 14 around the supporting pipe 12 and change the position of the wheel 15 relative to the horizon. This is extremely necessary to create the convenience of storage, transportation, skidding into and out of the room. therapeutic bike.

If it becomes necessary to change the geometric dimensions of the carrier pipe 12, it is possible to manufacture it from several parts. Fig. 7 shows an embodiment of three components, designated 12/1, 12/2 and 12/3, which form the element 12 using the connecting elements 14. Moreover, these parts can have different geometry both in cross-section and in shape.

To create increased rigidity of the carrier pipe 12, which can be demanded by both road conditions and other circumstances, a quick-detachable stiffener 22 and connecting elements are used 14. Closing the free ends of the carrier pipe, we create a rigid contour, thereby increasing the structural strength parameters.

An articulation of a quick-release stiffener 22 with a quick-release control handle 23 is shown in FIG. 7 and FIG. 8.

In cases where it is necessary to change the patient's fit on a therapeutic runaway, it is possible to use a back support 29, which is equipped with a soft pad 30. A rod 27 having a groove 26 is inserted into the horizontal part of the seat tube, allowing the rod to be adjusted for departure and then fixed to the selected position using the standard fasteners and hole 25. Groove 26 also guarantees the impossibility of completely removing the rod from the seat tube until the fasteners are removed from hole 25. The second end of the rod has a hole for the possibility of interfacing with cylindrical products, it is equipped with a slot and a clamp 32. By means of this, the rod 27 is connected to the axis 28. On the axis 28 there is another connecting element 14, in which the support for the back is installed. As a result, we get the opportunity to adjust the support for the back along the axis of the seat tube 10, along the axis 28, according to the angular position around the axis 28, as well as the reach and height, which allows you to choose the best position depending on the physical characteristics of the patient. The shape of the support for the back 29 may be anatomical. If necessary, you can use the fixation belt of the patient 31, adjustable in length and equipped with elastic elements.

The use of overrunning clutches in the wheel hubs makes it easier for the patient to keep the therapeutic runbike when moving uphill and protects him from a possible backward movement if the patient has not had time to apply the hand brake. Couplings can be installed in the front, in one of the rear, or in all wheels. Depends on the type of track on which traffic is planned. In the figures, the hand brake is not shown, since it is a standardized product.

The use of connecting elements 14 provides great opportunities for the modification of therapeutic runbike.

To reduce weight, aluminum alloys, Kevlar, etc. are used in most of the design of therapeutic runbike.

Details and various parts of the runbike are recommended to be painted or anodized in various colors, preferably bright. This will help create a chromotherapy effect for patients.

The therapeutic runbike has been tested in various road / off-road conditions and has fully demonstrated the properties described above. The data obtained suggest that the developed device ensures the achievement of the claimed technical result.
