Description

Physical therapy device for massaging and gravity traction of muscles beside vertebra

Technical Field

The invention relates to a medical appliance, in particular to a physical therapy device which can be used for traction of paraspinal muscles and joints of four limbs and vibration mechanical massage of the paraspinal muscles and ligaments.

Background

Types of therapeutic effects on paraspinal muscles and ligaments include: manual and mechanical (hardware) massage, traction (traction), vibration (vibramssage and vibratory traction), magneto-electric and electro-therapeutic, thermo-therapeutic radiation, etc. The most common of which are mechanical (vibrating machine) massage and traction.

Here, the main treatment and the type of therapeutic mechanical action on the paraspinal muscles and joints are briefly described.

Massage is a group of methods that produce therapeutic and mechanical dose effects on the paraspinal muscles and ligaments in the form of pressure, vibration, friction, stroking, etc. It may be used as a stand-alone therapeutic effect or in combination with other therapeutic methods (e.g., with vibration or traction). Often times, massage is used as a pre-traction effect.

Vibration is an impact aimed at increasing the therapeutic effect of mechanical massage or traction and is achieved using manually moved vibrators or by using special vibration sources built into the automated device of paraspinal muscle massage or traction.

Traction is a method of treating and preventing spinal disorders by creating traction along or at an angle to its axis. Treatment is usually based on taking measures to lengthen it to unload nerve endings, restore the intervertebral disc and correct the relative position of the vertebrae.

Mechanical therapy of the above type is preceded by thermal therapy. It is intended for the thermal relaxation of the paraspinal muscles and ligaments and can be performed by "internal" heat, for example, by performing gymnastic exercises, and due to external thermal radiation (heating with a hot air current, built-in thermal element devices in mechanical therapy, etc.). Due to the preliminary thermal effect on the patient's back, mechanical massage of his muscles and ligaments and stretching of the spine itself are promoted.

During mechanical therapy, the spinal column, its osteoarticular elements, and the paraspinal muscles and ligaments are treated and trained. This effect can be useful, for example, in preventing spinal curvature, improving the mobility of its links, preventing diseases such as lordosis, kyphosis, scoliosis and various types of postural disorders.

As shown in fig. 2, 3, the platform 2 is equipped with a horizontal shaft 3 and is rigidly connected thereto and can pivot relative to the frame 1 (see fig. 4 and 5). A cushion 4 is placed on the platform 2, the cushion is composed of cushion blocks 4-1, 4-2, …, 4-7, herein referred to as first cushion block 4-1, second cushion block 4-2, third cushion block 4-3, fourth cushion block 4-4, fifth cushion block 4-5, sixth cushion block 4-6 and seventh cushion block 4-7, when the head of the patient lies flat toward the first cushion block, the first to seventh cushion blocks correspond to the head, neck, back/chest (above lumbar), hip/thigh (below lumbar), calf, ankle and heel of the patient, respectively. That is, the third spacer 4-3 is where the patient's spine and paraspinal muscles are located. It can be seen from fig. 2 that the length of the third head block 4-3 in the longitudinal direction is the longest, the fourth head block 4-4 is slightly shorter than the third head block 4-3, the fifth head block 4-5 is slightly shorter than the fourth head block 4-4, and the first, second, sixth and seventh head blocks 4-1, 4-2, 4-6, 4-7 have the smallest length in the longitudinal direction. Each pallet is provided with rollers 38 so that it can be moved along rails 39 fixed to the upper surface of the platform 2 and held in place by locks 40.

In order to adapt to patients with different heights, particularly children or teenagers, cushion blocks or cushion block combinations with different lengths can be designed in advance, so that the height requirements can be adapted only by replacing the cushion blocks or the cushion block combinations when different patients are treated. Preferably, between adjacent (neighboring) head blocks of the mat 4 there are connecting elements 41, which connecting elements 41 are for example a fastening device to facilitate the removal and connection of different head blocks.

Fig. 6 is a schematic view of the construction of the pallet 4-3 of this embodiment, which shows the construction of only one roller of the pallet, but this embodiment of the invention has the same design for each roller of each pallet. Specifically, each pad has a front axle 38-1 and a rear axle 38-1, the four rollers 38 are disposed at two ends of the axles 38-1, the axles 38-1 and the pads are fixed to each other, and a pad pressure sensor 38-2 is disposed at a joint of the axles and the pads, each pad pressure sensor 38-2 is used for measuring a pressure carried by the pad, and the pressure is used for setting parameters of a treatment program in a subsequent treatment process.

The physical therapy device of this embodiment further comprises a platform tilting device comprising a first motor 5 fixed to the frame 1, the first motor 5 being connected to the horizontal shaft 3 of the platform 2 through a gear box to be driven.

The physical therapy device of this embodiment also comprises a massage unit, here embodied as an H-shaped massage wagon 6, the massage wagon 6 comprising an H-shaped frame and a massage roller 7 at the end of the frame, the massage wagon 6 being equipped with an electric vibrator 8 (fig. 7).

The physical therapy device of this embodiment further comprises a drive unit having a horizontal frame 9 configured to move on rollers 10 along a guide rail 11. The driving unit is connected to the bottom surface of the platform 2 and has a C-shaped cross-section (see fig. 20). The drive unit also has an inclined frame 12, one side of which is pivoted to the horizontal frame 9 and the other side of which is hinged to the massage unit. The drive unit also has a toothed belt 13 which is mounted on two toothed belt rollers 14, one of the toothed belt rollers 14 being driven by a second motor 15, whereby the toothed belt 13 conducts the driving force of the second motor 15 to the horizontal frame 9 and the drive unit.

The physical therapy device of this embodiment further comprises a hand control unit having a tongue 16 and a nut 17 welded to the inclined frame 12 and the horizontal frame 9 of the driving unit, respectively. The threaded portion 19 of the fork 18 interacts with the threaded engagement nut 17 of the massage vehicle, while the pressure shaft 20 can engage with the fork 18 (if necessary) and be equipped with a return spring 21 and a handle 22.

The physical therapy device of this embodiment also comprises a movement limiter 23 and two signalling

devices

24 and 25, a first signalling device 24 and a second signalling device 25, located in extreme positions. The movement limiter 23 is rigidly connected to the horizontal frame 9 and two signalling

devices

24 and 25 are fixed to the platform and signal when the movement limiter 23 is touched. The signalling means 24, 25 can be adjusted in their position along the platform 2 to facilitate the determination of different extreme positions for patients of different heights or massage needs.

The physical therapy device of this embodiment further includes a table inclination angle sensor made of a hall element, a semiconductor converter 26 of which is fixed to the housing, and a permanent magnet 27 mounted on the shaft of the first motor 5 of the table inclination unit.

The physical therapy device of this embodiment also includes a traction sensor and a stop pressure sensor, the traction sensor 28 being embodied here as a tension sensor, which is placed on a vertical pad 29 attached to the top of the platform 2. The stop pressure sensor 30 is placed on a vertical pad 31 attached to the bottom of the platform 2.

As shown in fig. 1 to 7, the physical therapy device of this embodiment further includes an acoustic signal device 32, a heating element 33, a controller 34, a fixing element 35 having a flexible connection 36, and a remote controller 37.

The input terminals of the controller 34 are connected to the tilt angle sensors (26, 27), the traction force sensor 28, the stop pressure sensor 30, the plurality of pad pressure sensors 38-2 and the output terminals of the two

signal devices

24 and 25, and the output terminal of the controller 34 is connected to the first motor 5 of the platform tilting device, the second motor 15 of the driving unit, the electric vibrator 8, the heating element 33 and the sound signal device 32. The remote controller 37 is connected to the controller 34 through a cable.

In one of the spacer blocks 4-3 of the cushion 4, a longitudinal rectangular recess 42 is formed to correspond to the position of the patient's spine on the cushion 4 and is closed from above by spacers 43. The heating element 33 is made of flexible graphite tape sewn into the spacers 43 of the mat 4.

The cushion 4 of the device is equipped with a headrest 44 and knee rests 45 and the platform 2 has a safety harness 46. Below the frame 1 of the device there are wheels 47, which wheels 47 are equipped with brakes (not shown).

The articulation between the horizontal shaft 3 and the frame 1 is provided by bearings 48. The reducer of the platform tilting device is realized on the basis of a worm gear pair consisting of a worm 49 and a worm wheel 50, which are rigidly connected to the shaft of the first motor 5 and to the horizontal shaft 3 of the platform 2, respectively.

The stopper 51 fixes the lower position of the stage 2. Stop 52 limits the movement of pad 4, thereby preventing the patient's head from striking traction sensor 28.

This embodiment may also be provided with a patient emergency button 53 connected to the controller 34 by a cable.

The frame 1 is the main load-bearing and structural component of the device of the invention, on which all other elements and components thereof are placed. The main purpose of the frame 1 is to ensure structural stability during medical treatment.

The electric vibrator 8 is designed to create vibrations of the massage roller 7 during the mechanical massage. It consists of a dc motor and an eccentric (not shown) attached to its shaft.

The cross section of the guide rail 11 is C-shaped, so that the horizontal frame 9 is prevented from falling out of the guide rail under the action of its own weight, and the movement of the guide rail 11 is realized strictly according to a predetermined track. The design of the guide rail is shown in fig. 20.

The second electric machine 15 is a direct current motor. Meanwhile, in the mounting process, the rotational motion of the rotor thereof is converted into the horizontal reciprocating motion of the massage roller 7.

The force with which the massage roller 7 is pressed against the back of the patient is determined by the level (height) at which the massage carriage 6 is lifted.

The limit

position signalling devices

24 and 25 are designed to generate a signal as to the arrival of the frame 9 at a given end position, so as to change its direction of movement.

The controller 34 provides for the storage and execution of the mechanical massage program and the traction program recorded therein. At the same time, the treatment program can be programmed (automated). In addition, it also stores thresholds for traction in the cervical, thoracic and lumbar vertebrae, too much traction possibly causing injury to the patient's spine. In a specific embodiment, these thresholds can be set to 20, 55 and 60kg, respectively, for example, but this can also be adjusted to the actual situation. The remote control 37 is designed to input program parameters and to display information received from the controller 34. Structurally, it is a combination of buttons and indicator lights.

And, the controller 34 selects the pressure value of the different pad pressure sensors 38-2 and the inclination angle obtained by the platform inclination angle sensor according to the position of the patient fixed by the fixing element 35 to calculate the actual traction force applied to the patient during the treatment process, and controls the traction treatment to the patient. In particular, the traction forces to which different parts of the patient are subjected vary due to the different positions of the patient to which the fixation element 35 is fixed. In order to monitor the actual traction force during traction, the present invention converts the pressure value measured by the pad under the fixing element 35 into an actual traction force, and the gravity applied to the human body part can be decomposed into a traction force part in the horizontal direction and a pressure part in the normal direction, and the pressure and the traction force are in tangent function, namely F _{Traction device} ＝F _{Press and press} *tg(α)。F _{Traction device} For tractive effort, F _{Press and press} For the pressure to which the pad is subjected, provided that F is measured _{Press and press} And the angle of inclination alpha, the actual traction can be calculated.

The

sensors

28, 30, 38-2 convert the tension and compression forces into appropriate electrical signals. The sound signal device 32 is used to inform medical personnel and the patient of the sound of the operation of the unit. The fixation element (strap) 35 with the flexible connection 36 is designed to apply a force to the corresponding part of the patient's body. The spacer 43 is intended to prevent the back of the patient from directly contacting the massage roller 7.

The headrest 44 and knee rests 45 are designed to facilitate placement of a patient on the cushion 4. In practice, the diameter of knee brace 45 may vary up to 250 mm. Generally, the knee rests 45 are used to increase the therapeutic effect of the mechanical massage procedure, since when the legs bend the knees, the longitudinal muscles of the back relax and the lumbar spine straightens slightly. This ensures a closer contact between them and the massage roller 7, thus ensuring a more effective impact thereof. Some designs of headrests 44 and knee rests 45 are shown in figures 18 and 19.

The harness 46 provides insurance against falling off during treatment for the patient's body. The gearbox implemented on the basis of the worm 49 and the worm wheel 50 is a "reduction" gearbox.

Next, the specific operation of the apparatus of this embodiment is described according to the following different procedures.

Prior to starting the treatment program:

the equipment must be firmly placed on a flat horizontal surface (floor);

its wheels 47 must be blocked by suitable brakes;

the position of all movable pads of the mat 4 must be fixed with the aid of the lock 40.

It is also desirable for the patient to wear a lightweight athletic garment prior to performing the procedure.

1. Mechanical (vibrating mechanical) massage of paraspinal muscles and ligaments

The operator helps the patient to sit correctly on the cushion 4 (fig. 9). The patient is supine such that:

his spinal axis coincides with the longitudinal axis of the pad 4,

the massage area of his back is located above the recess 42 of the 4 th-3 head block,

the head is located in the 4 th-1 or 4 th-2 th pad of the cushion (determined by anthropometric parameters of the patient).

On request of the patient, the operator places the headrest 44 and the knee rests under his head and knees. Knee brace 45 may be particularly useful as a folding towel.

After completing the instructions of the attending investigator, the operator records the treatment program in the controller via remote control 37. The set information may include, inter alia:

-date of treatment and full patient name;

-a level of heating;

the vibration level of the massage roller 7;

-the duration of the program;

-other options.

The next step is:

by pressing the handle 22 to engage the shaft 20 with the fork 18 and by rotating the handle 22 clockwise or anticlockwise, the inclination angle of the inclined frame 12 is changed, so as to set the desired level (height) of the massage roller 7, and therefore the degree of final pressing of the patient's back;

the border of the movement of the massage roller 7 along the patient's back is set by the signal means 24 and 25 along the table top 2;

-giving the patient a patient emergency button 53;

by pressing a "start" button (not shown) on the remote control 37, it starts the medical procedure in the device.

In the "start" signal, the controller 34 turns on the heating element 33, and starts the electric vibrator 8 and the second motor 15, accompanied by the double beep of the acoustic signaling device 32. The second motor 15 drives the horizontal frame 9, which in turn moves the inclined frame 12 with the massage roller 7. The latter rolls on the patient's back, giving a mechanical (vibromechanical) massage to the paraspinal muscles and ligaments.

At the moment when the movement limiter 23 appears above, for example, the first signaling device 24 generates a signal to the controller 34, which the controller 34 perceives as a signal switching the polarity of the supply voltage of the second motor 15. As a result, the second motor 15 starts to rotate in the opposite direction, thereby changing the moving direction of the massage roller 7.

The above-described change of the direction of movement of the massage roller 7 takes place in a similar manner when the movement limiter 23 is present above the second signalling means 25.

Thereby, the massage roller 7 performs a longitudinal mechanical vibration massage on the back of the patient by reciprocating. During such a massage, a partial portion of the spine undergoes micro-traction due to the change in the distance between the vertebrae. Under the influence of the massage effect, the spine is drawn to a certain extent, it is aligned and straightened, the invasion (squeezing) of nerve endings located near the vertebrae disappears, muscle spasms are relieved, the vertebrae resume normal activity, and the conductance of nerve impulses to internal organs and tissues is improved.

Furthermore, during the massage process, each vertebra of the spine performs a local movement in the sagittal plane. If vibration is enabled, additional vibration is superimposed on this movement of the vertebrae. As a result, the vertebrae undergo more complex periodic "massage" oscillations.

If an emergency stop of the installation is required during the treatment, the patient simply pushes the button 53. This will automatically stop the movement of the massage vehicle 6 and switch off the heating element 33 and the sound signal device 32 generates a multiple beep sound signal.

It is noted that vibration is used during mechanical massage if there is no contraindication to the patient. The adjustment of the elevation level of the massage roller 7 is performed only by the fixing frame 9, and the fixing frame 9 is located at the extreme position of the head of the cushion 4. It is recommended to perform the mechanical vibration massage starting from the lowest level of lifting the massage roller 7, gradually increasing their degree of pressing against the patient's back.

If the time limit for the massage program has expired, the controller 34 also stops the second motor 15, the vibrator 8, switches off the heating element 33 and switches on the sound signaller 32, the sound signaller 32 generating a single beep sound signal.

2. Head up traction cervical Spine (SHOP) procedure.

All therapeutic traction procedures can be performed by two methods. According to a first method, the load on the spine during a course of treatment increases during the course of treatment and decreases at the end of it. According to a second method, the load is periodically increased and decreased during an ongoing session. The particular distraction method is selected by the attending physician.

The patient is placed on the cushion 4. Next, a fixing element 35 is placed on his head, which fixing element 35 is connected to the traction force sensor 28 by means of a flexible connection 36.

Thereafter, the connecting elements 41 between the 4-2 and 4-3 head blocks (fig. 1 and 2) of the mattress 4 are disconnected, releasing the locks 40 of the head blocks 4-3, 4-4, 4-5, 4-6, 4-7, i.e. only the interconnected head blocks 4-1 and 4-2 remain in a fixed position.

After completing the instructions of the attending investigator, the operator writes the treatment program of the SHOP into the controller 34 via the remote controller 37. Such plans may include, among others:

-date of treatment and full patient name;

-a level of heating;

-a SHOP tractive effort (procedure) comprising maximum FBmax and minimum FBmin values of tractive effort;

a threshold value Fpor of the SHOP traction (generally not more than 20 kg), beyond which it is possible to cause a spinal injury to the patient;

-the duration of the program;

-other options.

The preparation of the procedure is completed by giving the patient the button 53.

Furthermore, by pressing the "start" button on the remote control 37, the operator starts the treatment process of "pulling the top" head "up" in the device, accompanied by the double beep sound signal of the sound signal device 32.

On the "start" signal, the controller 34 turns on the heating element 33 and starts the first motor 5 (fig. 8). The rotation of its rotor is transmitted to the horizontal shaft 3 through the worm 49 and the worm wheel 50 of the reduction gear, and the horizontal shaft 3 in turn starts to tilt (rotate clockwise) the platform 2. In this case, the total weight of the patient's body part, ru.t. shop (excluding head weight), will affect the 4-3, 4-4, 4-5, 4-6 and 4-7 pads of the mattress, which start to move along the guide 39 on the rollers 38. As a result, the weight of ru.t.shop is decomposed into two components: the normal force Fd pressure on the surface of the cushion 4 pad and the force fv. SHOP acting along this surface, i.e. SHOP traction (fig. 10 b). In this case, if we do not consider the coefficient of friction between the pads of the movable cushion 4 and the surface of the platform 2 in this case, the magnitude of the SHOP traction will be proportional to the angle of inclination α.

This force acts on the measuring element traction sensor 28 through the fixed element 35 and the flexible connection 36, which converts it into a corresponding electrical signal received for processing in the controller 34. The latter compares them with the given (programmed) traction value. The result of the comparison is sent to the first motor 5 in the form of a control signal. The controller 34 automatically stops the operation of the apparatus if the force fv. shop exceeds the traction force threshold Fthr during the procedure.

However, the actual value of the effective traction force fv. SHOP actually applied to the spine does not match the value of the sensor 28 due to the different body parts to which the fixation element 35 is fixed and the presence of frictional forces between the pad and the body. To this end, embodiments of the present invention more preferably calculate the actual fv. SHOP based on the pressure value measured by the pad sensor 38-2. As mentioned above, four pad sensors 38-2 are provided under each pad, and in the head-up cervical traction (SHOP) procedure, we select the total pressure Fs obtained by each pad sensor of the third, fourth, fifth, sixth and seventh pads _(3-7) The controller 34 may calculate the traction force fv, shift (α) Fs by the tilt angle _(3-7) . Where tg () is a tangent function, Fs _(3-7) Representing the sum of the pressure readings of the 3 rd to 7 th pads. Therefore, the controller calculates the actual traction force fv.SHOP in real time according to the actually obtained pressure value and angle of the cushion plate, and controls the inclination angle by controlling the action of the first motor, so that the traction force is maintained at a specific value or is changed within a range.

In addition, if an emergency stop of the installation is required during the treatment, the patient simply pushes the button 53. This will automatically stop the operation of the first motor 5 and switch off the heating element 33 and cause the acoustic signaling device 32 to generate multiple acoustic signals.

If the time limit of the SHOP pull sequence has expired, the controller 34 also stops the first motor 5 (returning it to its original position), turns off the heating element 33 and turns on the sound signal device 32, which generates a single beep sound signal.

3. Thoracic vertebra (GOP) procedure with head up distraction (fig. 11).

This process is implemented virtually the same as the process of pulling the SHOP.

As shown in fig. 11, the fixing elements 35 (chest straps) are placed at the level of the armpits. It is connected to the traction force sensor 28 with the aid of a flexible connection 36. Furthermore, the connecting elements between the head blocks 4-3 and 4-4 of the mattress 4 are disconnected and the locks of the head blocks 4-4, 4-5, 4-6 and 4-7 are closed, i.e. only the interconnected head blocks 4-1, 4-2 and 4-3 remain in a fixed position.

The operator writes the treatment program of the GOP into the controller 34 through the remote controller 37. Such settings may include, inter alia:

-date of treatment and full patient name;

-a level of heating;

-GOP traction forces (program) including maximum FBmax and minimum FBmin values of traction forces;

a threshold Fpor value for GOP traction (typically 55kg), beyond which it is possible to cause spinal injuries to the patient;

-the duration of the program;

-other options.

Further, by pressing the "start" button on the remote controller 37, the operator starts the medical procedure of "pulling the HOP" head "up" in the apparatus, accompanied by the double beep sound signal of the sound signal device 32.

The value of the GOP traction will also be proportional to the angle of inclination a:

where ru.t.gop is the weight of the patient's body part on the part of the movable pillow.

Further operation of the device is similar to its operation during SHOP traction. In the head-up traction thoracic vertebrae (GOP) program, one half of the total pressure value of the third pad 4-3, namely Fs is selected ₍₃₎ 2, and the pressure sum Fs obtained by the pad sensors of the fourth, fifth, sixth and seventh pads _(4-7) And calculate their sum as the total pressure, i.e. Fs ₍₃₎ /2+Fs _(4-7) The controller 34 may calculate the traction force fv, gop, (α) or (Fs) by the tilt angle ₍₃₎ /2+Fs _(4-7) ). Where tg () is the tangent function. Therefore, the controller calculates the actual traction force fv.GOP in real time according to the actually obtained pressure value and angle of the cushion plate, and controls the inclination angle by controlling the action of the first motor, so that the traction force is maintained at a specific value or is changed within a range.

4. Head up traction lumbar spine (POP) procedure (fig. 12).

The implementation of this procedure is virtually indistinguishable from the implementation of the GOP pulling procedure.

As shown in fig. 12, the fixation element 35 (pelvic girdle) is placed on the patient's belt, just above the pelvic bones. It is connected to the traction force sensor 28 with the aid of a flexible link 36.

Subsequently, the coupling elements 41 between the head blocks 4-3 and 4-4 of the mattress 4 are disconnected, and the locks 40 of the head blocks 4-4, 4-5, 4-6 and 4-7 are released, i.e. only the interconnected head blocks 4-1, 4-2 and 4-3 remain in a fixed position.

The operator writes in the controller 34 for treatment POP through the remote controller 37. Such plans may include, among others:

-date of treatment and full patient name;

-a level of heating;

-POP tractive effort (program) including maximum FBmax and minimum FBmin values of tractive effort;

a threshold value Fthor of POP traction (typically 60kg), beyond which it is possible to cause spinal injuries to the patient;

-the duration of the program;

-other options.

Further, by pressing the "start" button on the remote controller 37, the operator starts the "POP pull" and "head up" treatment program, and the pull value of POP is also proportional to the tilt angle α in accordance with the double beep signal of the audio signal device 32.

Further operation of the device is similar to that of a GOP, except for fv _(4-7) I.e., the pressure sum Fs obtained from the pad sensors of the fourth, fifth, sixth and seventh pads only _(4-7) To calculate traction and fv.

5. Head-down traction Lumbar Spine (LSP) procedure.

Fig. 13 shows another variation of POP traction, i.e., when the patient's head is facing downward during traction.

Initial position of the patient-on the "horizontal" platform 2, with his head facing downwards.

The fixation element 35 (pelvic girdle) is placed on the patient's belt, just above the pelvic bones. It is connected to the traction force sensor 28 with the aid of a flexible connection 36.

The connecting elements 41 between the 4-4 and 4-5 head blocks (fig. 1 and 2) of the mattress 4 are disconnected and the locks 40 for the 4-5, 4-6 and 4-7 head block positions are disconnected, i.e. only the interconnected head blocks 4-1, 4-2, 4-3 and 4-4 remain in a fixed position.

The further operation of the device is similar to that described above except that fv _(5-7) I.e., the pressure sum Fs obtained from the pad sensors of the fifth, sixth and seventh pads only _(5-7) To calculate traction and fv.

Note that the selection of the POP traction method (fig. 12 or fig. 13) is made by the attending physician based on the results of the patient's preliminary examination.

All of the above described traction procedures may be preceded by a "mechanical (vibromechanical) massage of the paraspinal muscles and ligaments" procedure.

6. Knee joint distraction (KS) procedure.

Initial position of the patient-on the "horizontal" platform 2, with his head facing downwards. Figure 14 shows the position of the joint tape 35 with the flexible connector 36 thereon when the knee joint is distracted.

The connecting elements 41 are disconnected between the head blocks 4-3 and 4-4 of the mattress 4 (fig. 1 and 2) and the locks 40 of the positions of the head blocks 4-4, 4-5, 4-6 and 4-7 are released, i.e. only the interconnected head blocks 4-1, 4-2 and 4-3 remain in a fixed position.

Further operation of the device is similar to that described above, fv.ks ═ tg (α) × Fs _(4-7) 。

7. Traction ankle joint (GS) procedure.

Figure 15 shows the patient's placement on the pad 4 and the position of the joint strap 35 with flexible connectors 36 during ankle traction (unloading).

The connecting elements 41 between the head blocks 4-3 and 4-4 of the mat 4 are disconnected (fig. 1 and 2) and the locks 40 of the positions of the head blocks 4-4, 4-5, 4-6 and 4-7 are released. I.e. only the interconnected head blocks 4-1, 4-2 and 4-3 remain in a fixed position.

The further operation of the device is similar to that described above except that fv _(3-7) I.e., the pressure sum Fs obtained from the respective pad sensors of the third, fourth, fifth, sixth and seventh pads _(3-7) To calculate traction and fv.gs.

8. Verticalization mode procedure (fig. 16).

The "verticalization mode" procedure is intended to restore the function of the vestibular apparatus of a patient-training his vertical standing function (e.g., after prolonged bed rest or weight loss).

The initial position of the patient is horizontal on the platform 2. At the same time, his head is facing upwards and both feet are placed on the gravity sensor 30. All locks 40 for the mat 4 cushion positions are locked and a safety strap 46 is used to prevent the patient's body from falling.

The procedure of the treatment procedure may for example be as follows:

in the first phase, the platform 2 rotates with the patient through a relatively small angle β and stops. The stop pressure is measured using sensor 30, the value of which is fixed in controller 34. After a predetermined period of time, return to its original horizontal position.

This process is repeated a predetermined number of times.

In the second phase, the platform 2 is rotated with the patient by a slightly larger angle and stopped again. Using the gravity sensor 30, the stop pressure is again measured, the value of which is again fixed in the controller 34. After a predetermined period of time, the platform 2 returns to its original horizontal position.

The process is also repeated a predetermined number of times.

At each new stage, the value of each of the angles is increased. As a result, in the controller 34, a table of values for the angle β and corresponding pressure values of the patient's foot on the load cell 30 is formed (stored). The resulting table can be used as the basis for analysis to "verticalize" the program and subsequently correct the parameters of the program.

"Manual massage" or "Manual treatment" mode procedures.

This procedure is suitable for performing manual massage or manual treatment.

The initial position of the platform 2 is horizontal. Typically, the patient lies face down on the mattress 4. Next, the operator rotates the platform 2 to a convenient angle (fig. 17). Previously, the patient was secured with a harness 46. Next, a process of directly performing manual massage or manual treatment is started.

During the execution of this procedure, the operator can quickly change the angle of the platform 2, if necessary.

8. And performing activities after treatment.

The post-treatment activities begin with the examination of the patient by the attending physician. After examination, the patient is sent to a rest room for 10-15 minutes of treatment and then rests, thereby fixing the achieved effects of massaging and traction of the intervertebral disc and releasing the neurite. In some cases, additional relaxation massages, including passive gymnastics, pharmacotherapy, physiotherapy, etc., are suggested as determined by the attending physician.

The present invention thus solves the problem of the functioning of the traction device, providing the ability to perform all-round manual and mechanical massage thereon, as well as oblique gravity traction of the paraspinal muscles and joint parts.

Creating more comfortable conditions for the patient (headrests, knee rests, etc.) when performing the medical procedure. The risk of injury is reduced when performing a traction procedure, since the emergency stop device can be emergency stopped using the patient's emergency button 53. Furthermore, the spacers 43 reduce the risk of injury to the back of the patient during mechanical massage using the massage rollers 7.

The present invention enables adjustment (change) of the mechanical massage area by changing the position of the first signaling device 24 and the second signaling device 25.

The invention greatly facilitates the work of doctors and operators (nurses). The presence of the remote control 37 facilitates the entry of program parameters. Due to the presence of the wheels 47, its mobility is ensured and it can be quickly reinstalled in the room.

The invention can be used for various types of medical, spa-matical massage and for permanent or periodic traction of the spinal column (traction therapy).

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
