Description

The utility model relates to a simulator used in sports, during rehabilitation, including in field and hiking conditions, for prevention, aesthetics, in sports medicine for the treatment, rehabilitation and prevention of various diseases of the spine.

A therapeutic and prophylactic chair is known from the prior art (see RF patent No. 59409 for a utility model, published on December 27, 2006).

The utility model relates to devices for the prevention and treatment of human back diseases such as osteochondrosis, scoliosis and can be used in medical institutions, at home and as office furniture.

The therapeutic and prophylactic chair consists of a seat, a vertically movable backrest, curved in the lumbar region, a mechanism for lifting the armrests and headrest, installed on a U-shaped reclining stand fixed to the base, characterized in that the backrest is equipped with axillary supports, and the armrests have built-in backrest drive mechanisms driven by handles with locks.

The disadvantages of the known chair are:

low effectiveness of treatment and prevention of various diseases of the spine (there is no possibility of extending the backrest relative to the seat and rotating (deviating) the angle of the backrest in different directions relative to the seat, the impossibility of influencing different parts of the spine);

inconvenience in use and operation for the patient: there is no support for the knees and legs, there is no possibility of fixing the hips and chest, there is no possibility of controlling and adjusting the lumbar support, backrest and seat depending on the patient’s physique and his capabilities.

The traction systems DRX9000 and DRX9500 from Axiom Worldwide, USA, are known from the prior art for the treatment of low back pain by decompressing intervertebral discs and joints due to distraction (stretching) and positioning (see https://docs.nevacert.ru/files/med_reestr_v2 /13049_instruction.pdf).

The systems contain a table for placing the patient, a computer system for controlling the parameters of the procedure with a touch control panel, a display, a printer and an operator’s hand-held remote control, a knee support, and an emergency switch. The table is equipped with a system for fixing and securing the patient during the procedure, including a triangular-shaped kneecap and a removable headrest of an open design with a tensioning forehead strap connected to an electromechanical traction device, which has a feedback loop. The table can be rotated from horizontal to vertical position using microprocessor-controlled motors. The compound table design allows the table to expand to reduce friction on the vertebrae and allow for separation.

The disadvantages of the known systems are:

simple traction is used in one plane, with the legs bent at the knees, which leads to discomfort for the patient;

the effect on the spine is usually carried out within the lumbosacral region. The impact on the higher parts of the spine is not provided due to the design features and methods of fixing the patient;

there is no possibility of horizontal rotation of the backrest;

the patient is exposed only according to a predetermined program;

there is no variability in force, the procedure is performed in all patients according to the same algorithm;

large dimensions.

The purpose of the claimed utility model is to create a convenient and easy-to-use multifunctional mobile simulator with small dimensions for the treatment, rehabilitation and prevention of various diseases of the spine.

The technical result of the claimed utility model is the possibility of influencing the spine in the range from the lower lumbosacral to the middle thoracic regions.

The technical result of the utility model is achieved by the fact that the kinesitherapy mobile rehabilitation simulator (TCRP) (see Fig. 1 - 8) is a chair-bed transformer and consists of:

interconnected by two drives (16) and (19) of a seat (3) with supports (1) for the legs and adjustable stops (2) for the knees, a backrest (5) with protrusions-supports (20) for the forearms and arms and with armpits movable and sliding supports - rods (10), and lumbar support (4), mounted on a frame (14) with legs (21) for level adjustment;

fixators (8, 9) of the hips and chest;

drive (16) for lowering/raising the backrest (5) from vertical to horizontal position and back;

drive (19) for moving the backrest (5) lowered to a horizontal position from the seat (3) horizontally;

a rotating mechanism for the possibility of rotating the backrest (5) at a certain angle in the horizontal plane, left-right, relative to the seat (3) by both the patient and the operator;

means for limiting the maximum rotation of the backrest relative to the seat;

control panel (6) on a movable rod.

In particular embodiments, the TCRP is configured to:

raising the back (5) and/or seat (3) to a certain vertical angle when the back (5) reaches a horizontal position;

control and adjustment of the degree of extension of the backrest (5) relative to the seat (3);

adjusting and fixing the axillary supports (20) relative to the back (5), for example, using a screw (11);

adjustment and fixation of the lumbar support (4) along the axis of the perpendicular backrest (5) depending on the patient’s lordosis, for example, using a screw (7) or an electric drive;

adjusting and fixing the knee support (2), for example, using a screw or an electric drive.

TCRP can be configured to limit the maximum extension of the backrest (5) relative to the seat (3) and/or rotation of the backrest (5) relative to the seat (3).

For example, a hydraulic, pneumatic or electric drive can be used as a drive (19) for expanding the backrest (5) relative to the seat (3) horizontally and a drive (16) for lowering/raising the backrest (5). For example, belts are used as restraints (8, 9) for the hips and chest. Other fasteners may also be used.

Example implementation and operating principle.

The patient sits in a transformable chair on the seat (3) (see Fig. 1 - 8), holding comfortable handrails with his hands, the legs under the patient’s knees are slightly raised and supported by stops - rollers (2), feet rest on supports - rollers (1 ). With the help of a control pneumatic drive (16), the back (5) of the chair smoothly takes on a horizontal position. The support (2) for the knees is adjustable. The mechanism (12) for adjusting and fixing the support (2) for the knees can be mechanical, for example, in the form of a screw (25) or have an electric drive. The operator secures the patient with wide belts (8) and (9) in the pelvis and hypochondrium. The back (5) and seat (3) of the TCRP are connected to each other by pneumatic rods of pneumatic actuators (16) and (19), located under the chair and connected to the compressor.

The patient's armpits rest against movable, sliding supports - rods (10), and the forearms and hands lie on the protrusions - stands (20) of the backrest (5). The axillary supports (10) are adjustable in two planes depending on the patient’s body type. Under the patient's back, in the lumbar region, on the seat (3) there is a lumbar support - a lordosis roller (4), which is individually adjustable. This allows the patient, when changing the distance between the back (5) and the seat (3) of the TCRP, to lie comfortably, with his entire back tightly adjacent to the surface of the chair. The back (5), seat (3) and lumbar support (4) are mounted on a frame (14) with legs (21) for level adjustment. The control panel (6) is placed on a movable rod and is a box measuring 25 x 30 cm, 6 cm thick. Inside the box there are pneumatic distributor controls, safety valves, and flow regulators. The front panel of the remote control contains: a pressure gauge, a button to end the procedure and a button to turn on/off the equipment. End procedure button - allows you to instantly relieve pressure if it is required for any reason. The control panel (6) can have various implementation, installation and placement options.

The doctor-operator or the patient independently turns on the compressor to supply air to the pneumatic rod of the pneumatic drive (19), pumping pressure into the pneumatic drive (19) connecting the back (5) and the seat (3) of the TCRP. The back (5) smoothly moves away from the seat (3) horizontally (along the X axis) by several centimeters, proportional to the amount of compressed air supplied to the pneumatic drive (19). Further, according to his feelings, the operator or patient independently gradually increases the supply of compressed air, bringing the compressor readings to 1.5-2.5 atm, the backrest (5) moves away from the seat (3) a few more cm. Control over the degree of extension of the backrest ( 5) relative to the seat (3) horizontally is carried out using a pressure gauge and the patient’s own sensations. Depending on individual sensations, the operator or patient independently regulates the supply of compressed air to the pneumatic drive (19), thereby adjusting the degree of stretching by cyclically decreasing or increasing the pressure in the pneumatic drive (19). In this position, almost the entire spine of the patient is unloaded and does not experience pressure from the weight of his own body on the spinal column. These effects can also be done automatically. If the force seems excessive, the patient presses the air release button. The patient’s entire body, muscles and spine are slightly stretched, the patient begins to independently rotate the back (5) to the left – to the right along the horizontal axis relative to the seat (3). From such an impact, the vertebrae and intervertebral discs are unloaded, the distance between them increases slightly, the pinched nerve endings fall out of the intervertebral zone and take up space outside the pinched area, the pain goes away. The backrest (5) can be rotated relative to the seat (3) by both the patient himself and the doctor-operator. After performing several stretching cycles, the operator, if necessary, establishes the stability of the entire structure by adjusting the 4 stops under the legs of the TCRP, which makes it possible to compensate for changes in the patient’s spine and, according to his feelings, give the body a horizontal position. Movements of the backrest (5) to the left and right along the horizontal axis relative to the seat (3) at the moment of unloading are carried out at approximately an angle of up to 15 - 30 degrees (according to the patient’s own sensations). The degree of horizontal deviation of the back (5) relative to the seat (3), and at the same time stretching of the spine, is adjusted by the operator according to the patient’s sensations or by the patient independently. This allows you to additionally influence the back muscles, vertebrae, intervertebral discs and pinched nerve endings, which, once free, come out of the pinching and pain in the spine decreases or disappears.

The duration of exposure, the number of cycles, and the degree of stretching depend on the characteristics and duration of the patient’s disease, his weight, build, age, and individual sensations. Typically exposure time is 15 to 40 minutes while lying on your back on TCRP.

At the end of the session, the operator bleeds the air to zero, removes the fixing belts (8) and (9) and leaves the patient to lie horizontally on the TCRP for another 15 - 20 minutes. After this, acting on the pneumatic drive (16), the TCRP is switched to chair mode, the backrest (5) is switched to a vertical position.

The patient gets up and goes to lie down for 30-40 minutes on a semi-rigid bed. After the procedure, the patient is drawn to sleep and there is no need to resist this. After the procedure, the patient may experience an unusual sensation in the spine, the disappearance of pain, lightness in the body and even a good mood. The number of sessions is individual and depends on many reasons, but usually ranges from 3 to 15, performed either every day or every other day or two. Everything is decided by the specialist, drawing up a recovery protocol for the patient.

The declared TCRP has the following differences and advantages over similar developments:

there is an additional possibility of horizontal movements of the back (5) relative to the seat (3) to the left - to the right along the horizontal axis with an unloaded spine;

the device allows you to influence the spine cyclically, increasing and decreasing the degree of stretching by supplying compressed air to the pneumatic drive (19) according to the patient’s sensations;

It is possible to control the impact on the patient both by the operator manually or according to a given program, and by the patient independently, which allows him, according to individual sensations, to increase and decrease the degree of impact on the drive, monitoring this using a pressure gauge and other control devices. In this case, the operator helps the patient in all manipulations;

the patient can independently, according to his own feelings, regulate the degree of extension and rotation of the backrest (5) and traction of the spine;

the impact on the spinal column is carried out from the middle thoracic region to the lower lumbosacral region. The reduction of pain, up to its complete disappearance, occurs due to the release of pinched nerve endings. This is achieved by increasing the interdiscal space, decompressing the intervertebral discs and reducing herniation;

even with an accidental, uncontrolled press on the air supply handle, spontaneous expansion of the backrest (5) and damage to the spine are excluded, since the compressor is equipped with a limiter for the injection of pressure into the pneumatic drive (19). There is also a restrictive steel chain between the backrest (5) and the seat (3).

TCRP can be used both in emergency cases - to relieve pain in the spine, and for prevention, as well as rapid relaxation of a “tired back”.

TCRP can be used in cases of scoliosis and other similar spinal defects.

The design of the TCRP is such that it can be used without additional changes for patients with a height of 140 to 190 cm, and a fullness of up to size 46 to 58-60.

The main difference from similar devices is the possibility of influencing the sore spot not only in the horizontal plane, using traction along the spinal column (along the X axis), but also additionally influencing it by turning the backrest (5) at an angle from 0 to 45- 55 degrees in the horizontal plane (horizontal axis) relative to the seat (3). This possibility is achieved by a design feature of the simulator, which allows the back (5) of the TCRP to be tilted at an angle from the horizon to the left and right, both by the patient himself and with the help of forced influence. At the same time, in manual mode, it was revealed that the patient subtly feels at what angle and at what speed he needs to turn his body. These movements are performed almost effortlessly due to the rotating mechanism at the bottom of the TCRP.

The TCRP has the ability to limit the maximum extension of the backrest relative to the seat.

For this purpose, the device provides a three-stage limiter for increasing the gap between the seat and the backrest:

1 - maximum pressure limiter in the compressor;

2 - limiter of the maximum output of the rod in the pneumatic drive;

3 - a steel chain, loosely attached between the back and the seat, limits the stroke of the pneumatic drive.

To raise/lower the backrest (5) relative to the seat (3), various means, devices, mechanisms can be used, for example, a hydraulic, pneumatic or electric drive (16).

To expand the backrest (5) relative to the seat (3), various means, devices, mechanisms can be used, for example, a hydraulic, pneumatic or electric drive (19).

To rotate the backrest (5) at a certain angle in the horizontal plane, left-right, relative to the seat (3), various well-known rotary mechanisms and means can be used.

For convenience, the patient himself or the doctor-operator can raise the backrest (5) and/or the seat (3) to a certain vertical angle when the backrest is in a horizontal position. For this purpose, the simulator may have various rotating mechanisms and means, as well as position locks.

For the patient’s convenience when performing procedures, the back (5) has protrusions - supports for the forearms and hands.

With the help of the declared TCRP, it is possible to both relieve the spine, reducing the time for rest, and when used for a year, 2-3 times a week, increase height by 2-3 cm.

Thanks to the use of TCRP, the rate of development of scoliosis in adolescents is reduced and, with regular use over a long period of time, it practically disappears.

The result of TCRP is a significant reduction in pain and elimination of problems in the spine caused by herniated intervertebral discs, their degenerative disease, sciatica - irritation of nerve endings that occurs when it is compressed, as well as articular surface syndrome. The effect is achieved by stretching the muscles and vertebrae and increasing the distance between them and between the intervertebral discs, which leads to the reduction of intervertebral hernias, the release of pinched nerve endings and, ultimately, the relief of pain.

The claimed simulator can be used to relieve tension, restore performance and relieve pain in the back, sections from the lower lumbosacral to the middle thoracic regions and can be used in sports, during rehabilitation, including in field and camping conditions, on ships, underwater boats and other similar conditions, for prevention, aesthetics, in sports medicine.

Although the claimed simulator is shown and described with reference to certain preferred embodiments and implementations, those skilled in the art will appreciate that various changes in form and content may be made therein without departing from the spirit and scope of the utility model, which determined by the attached formula taking into account the description and drawings.
