The invention is illustrated by drawings.

Figure 1 shows a consolidated structural diagram of the inventive device, showing the mechanical, electrical and thermal connections operating in it.

Figure 2 shows a structural diagram of the device.

Figure 3 explains the regulation of the direction of the traction forces of the cervical spine.

Description of the device in statics.

The device (figure 1, 2) contains a base 1, cervical 2 and thoracic 3 traction units, traction drive 4, traction drive control unit 5, a traction force sensor, made, for example, in the form of a strain gauge 6, a thermal impact unit 7, the first 8 , the second 9 and third 10 vertical racks, the movable carriage 11 and the first sleeve 12.

The cervical traction unit 2 consists of a sliding rod 13, a second sleeve 14, a distributor 15 of the traction forces of the cervical spine (Fig. 1), made, for example, in the form of a rocker 16, the first flexible connection 17 and straps 18 of the cervical spine.

The thoracic traction node 3 consists of a first horizontal arm 19, a second flexible connection 20, an adjuster 21 for the angle of extension of the thoracic spine, made, for example, in the form of a roller 22, a second horizontal arm 23 and a movable latch 24, and straps 25 for attaching the thoracic spine.

The traction drive 4 is made in the form of a screw-nut mechanism consisting of a "screw" 26 and a "nut" 27, and is equipped with a gear motor 28 consisting of an electric motor 29 and a worm pair based on the worm 30 and the worm wheel 31 mounted on "screw" 26. In this case, the input of the electric motor 29 is the input of the traction drive 4.

The traction drive control unit 5 consists of a data amplifier 32 connected in series, an analog-to-digital converter 33, a signal processing unit 34 and a power amplifier 35 and is equipped with a control panel 36.

The load cell 6 is placed on the base 1 and is designed to generate signals proportional to the forces of traction.

The heat exposure unit 7 consists, for example, of a heater (heater-blower) 37, a supply hose 38 (not shown in FIG. 2) and a guide nozzle 39.

The base 1 is made mobile, for which it is equipped with wheels 40 (figure 2) with locking elements (not shown). Base 1 also has docking elements 41, with which it can be connected to a medical bed (table, couch) 42. In the prototype device manufactured by the applicant, base 1 is docked to the massage table and manual therapy described in [19] .

In addition, the base 1 can be equipped with a counterweight 43 (figure 2) and / or a detachable platform 44 for accommodating the patient, which is connected to the base 1 with the help of the connecting elements 45. The counterweight 43 can be made of concrete or cast iron and is designed to compensate for the overturning moment (directed clockwise in figure 2), acting on the device when stretching the cervical spine.

In the cervical traction unit 2, a sliding rod 13 is placed inside the first sleeve 12. At the same time, its position is fixed with a locking screw 46. At the end of the sliding rod 13 is fixed perpendicular to the second sleeve 14 with a locking screw 47, inside of which a beam 16 is mounted (in FIG. 2 sleeve 47 and rocker 16 are conventionally inclined). Some ends of the first flexible connection 17 are connected to the shoulders of the rocker arm 16, and the other ends to the straps 18 of the cervical spine. The latter during traction are placed on the cervical spine 48 and the patient's head (figure 1).

In the chest traction unit 3, the first bracket 19 is mounted on the carriage 11, and the roller 22 of the regulator 21 is attached through the second bracket 23 to the movable latch 24 mounted on the rack 8. Moreover, the second flexible connection 20 is placed on the roller 22 and connected at one end to the first bracket 19, and the other end - with straps 25 fastening the thoracic spine. The latter during traction are placed on the thoracic region 49 of the spine of the patient (figure 1).

In the traction drive 4, the “screw” 26 of the screw-nut mechanism is mounted on the load cell 6, and the “nut” 27 is connected to one end of the strut 9, the other end of which is pivotally connected to the carriage 11.

In the prototype device manufactured by the applicant, the gear motor 28, together with the screw-nut mechanism, was implemented on the basis of the Megamat MBZ 45252 DEWERT product.

In node 5, the input of the information amplifier 32 is the input, and the output of the power amplifier 35 is the output of this node. Block 34 of node 5 can be made on the basis of a microcontroller that provides reception, storage and implementation of a spinal traction program. The control unit 5 is an “electronic” unit of the device and can be structurally located inside the base 1. In this case, the control panel 36 can be made remote, which is connected via cables to the device.

In the node 7 of the thermal effect, the air heater 37 can also be placed inside the base 1 (figure 2), the inlet hose 38 is inside the cover casing 50 of the device (casing 50 is shown conditionally in figure 2), and the guide nozzle 39 is placed on the casing 50 at a level neck of the patient.

The first rack 8 of rectangular cross section, mounted on the base 1, serves as a guide for the movable carriage 11, In addition, the rack 8 is used when fixing at the desired level of the regulator 21 of the angle of extension of the thoracic spine.

The second rack 9 provides the transfer of traction from the "nut" 27 to the carriage 11. In this case, the "articulation" of the joints between the latter eliminates inaccuracies in the manufacture of the rack 8 and the carriage 11.

The third post 10 is installed at one end on the carriage 11, and the first sleeve 12 is horizontally mounted on the other end and is designed to transmit traction from the carriage 11 to the sleeve 12 and further to the cervical traction unit 2. The stand 10 is removable from the carriage 11, which is convenient when transporting the device. In the prototype device manufactured by the applicant, the stand 10 is attached to the carriage 11 with two bolts (see figure 2).

The arms of the rocker arm 16 along the entire length have grooves 51 for moving and engaging the flexible connection 17 (Fig.3, a). The rocker 16 itself can also move along its axis inside the sleeve 14 and can be fixed using the locking screw 47 (Fig.3, b). In addition, loosening the locking screw 46 and turning the sliding rod 13 around its own axis, you can change the angle of inclination of the rocker arm 16 to the horizon (Fig.3, c).

The described device can be performed in two versions. In the first version, the patient, when stretching his cervical spine, is placed on a stool, and in the second case he occupies a standing position. Structurally, these device options are the same and differ only in height (rack length 10).

Description of the device in dynamics.

Before starting the operation of the device, depending on which part of the patient’s spine (cervical or thoracic) will be stretched, a nurse (operator) through the control panel 36 enters the traction program into the signal processing unit 34 through the control panel 36. Such a program may include, for example, the following operations:

1. A smooth increase in traction from zero to a predetermined maximum value.

2. Exposure for a predetermined time interval of the reached maximum value.

3. A smooth decrease in traction force from a maximum value to zero or a minimum value.

4. Periodic repetition of the above operations a specified number of times.

In accordance with this program, the maximum and minimum traction forces, the duration of the holding interval, the number of repetitions of the traction cycles and other data, for example, the rise time and the decrease in the traction force, are entered in block 34.

In the case of extension of the cervical spine, the operator connects to platform 1 using docking elements 45 platform 44 (if it is part of the device) and then places the patient on a chair or on this platform, or on the floor. Or the patient is standing on the floor or on site 44. In all cases, the patient is placed with his back to the rack 9.

The fixing of the base 1 on the floor is carried out using special stoppers placed on the wheels 40.

At the next moment, the operator turns on the air heater 37 and, with the help of the nozzle 39, directs the heated air to the desired section of the cervical spine, due to which heat massage is performed (if such massage is provided for by the treatment procedure).

It should be noted that preliminary thermal massage is an important procedure that reduces muscle spasm during traction (see, for example, [17, p.126]).

Upon completion of the thermal massage, the operator places fastening straps 18 on the cervical spine of the patient and on his head. At the same time, the patient’s torso and arms (for example, to the chair) are not fixed, since the lifting force of the traction (not more than 20 kg) is much less than the weight of a person’s body.

It should also be noted that in the treatment of diseases by stretching the cervical spine, it is advisable to exert traction efforts only on certain sections of it. The above can be achieved if it is possible to adjust the directions of the force vectors in the frontal and sagittal planes [17, p.128-132].

In the described device, coarse adjustment of the direction of the vector (angle β) of the traction force in the frontal plane (in the plane perpendicular to the plane of the drawing of FIG. 2) is carried out by throwing the flexible connection 17 from one groove 51 of the rocker to another (FIG. 3, a). Smooth adjustment of the angle β is provided by moving the rocker 16 along its own axis inside the sleeve 14 by a certain distance Δ (Fig.3, b).

With differential traction in the frontal plane, the magnitude of the traction force is adjusted by setting the rocker arm at an angle γ to the horizontal (Fig. 3, c). To do this, just turn the rod 13 [17, p. 131] at the desired angle around its own axis.

Adjusting the direction of the vector of the traction force in the sagittal plane (in the plane of the drawing of figure 2) is carried out by moving the sliding rod 13 along its own axis.

Next, the operator from the remote control 36 starts the traction program. As a result, the signals from block 34 are fed to a power amplifier 35 and then to an electric motor 29. The rotation of the rotor of the latter is transmitted to the worm 30, which rotates the worm wheel 31, and with it the screw 26 of the screw-nut mechanism. The rotation of the "screw" 26 is converted in this mechanism into the translational movement of the "nut" 27, pushing the rack 9 up. The latter moves along the rack 8 the carriage 11, and with it the rack 10, the sleeve 12 and the cervical traction node 2. As a result, the traction force is applied to the cervical 48 of the patient's spine.

The traction force is measured by a strain gauge 6 located under the "screw" 26 of the screw-nut mechanism. Information signals from the strain gauge 6 are amplified by the amplifier 32 and through an analog-to-digital Converter 33 in digital form enter block 34, where they are compared with the values of the traction force specified by the program. The results of this comparison are worked out by the nodes 4 and 5 of the device.

The current values of the traction force are displayed on the remote control 36 control.

Upon completion of the traction program according to signals from block 34, the traction drive returns the device to its original state. The end of the program is accompanied by a sound signal (the sound source is not shown in the drawing).

In the case of extension of the thoracic spine, the operator places the patient on the bed, table, couch 42 and moves the base 1 on wheels 40 to the end of the bed. In this case, the docking of the base 1 to the bed 42 is provided by the docking elements 41. Additional fixation of the base 1 on the floor is carried out using stoppers placed on the wheels 40.

Next, the operator places fastening straps 25 on the thoracic spine of the patient. Adjusting the angle α traction of the thoracic spine (figure 2) is provided by moving the roller 22 along the rack 8 (figure 2).

Further operation of the device is similar to that described above. The operator enters and starts the traction program. The bracket 19, moving up, pulls a flexible connection 20, through which the traction force is transmitted to the straps 25 and the thoracic section 49 of the patient's spine.

The end of the traction program is also accompanied by a sound signal.

Thus, the described device is characterized by the following features:

1. It has a wider functionality than that of the prototype, as it allows traction of both the cervical and thoracic spine. Moreover, almost the same elements are used for this: base, traction drive, traction drive control unit, traction force sensor, movable carriage, first and second racks.

2. There is the possibility of a smooth dosed extension of both the cervical and thoracic spine at different angles, which is important in the treatment of many diseases of the spine [17].

3. Has the ability to stretch the cervical spine of the patient, located in both sitting and standing positions.

4. It allows for thermal massage of the cervical spine, which relieves spasms of its muscles.

5. Minimizes the physical labor of the operator, since traction operations are performed almost automatically.

6. The device is adapted for indoor movement.

7. It occupies a small area, the design is relatively simple and safe to use.

8. Does not require highly trained specialists. The traction is carried out by the methodologist or instructed nurse. In the case of remote control, the patient can control the device independently.

Verification of patentability conditions "industrial applicability".

The proposed device for traction of the spine does not cause difficulties in the manufacture and can be industrially mastered. A prototype table was tested by the applicant for a month in operation.

The above information indicates for the claimed device, as it is described in the claims, about the possibility of implementing it using known and proposed methods and means. Therefore, the claimed invention meets the condition of patentability "industrial applicability" under applicable law.
