Description

The invention relates to the technical means used in the conservative treatment of certain diseases of the spine: discogenic radiculitis, spondylosis, osteochondrosis. BACKGROUND OF THE INVENTION BACKGROUND OF THE INVENTION BACKGROUND OF THE INVENTION BACKGROUND OF THE INVENTION BACKGROUND OF THE INVENTION Devices for underwater spinal stretching are known, including a bath, a cable, a cable, a loading unit, and a control unit. However, such devices are distinguished by the relative complexity of the kinematic scheme, the narrow range, the loading limits and the lack of automatic maintenance of a given stretching mode. The purpose of the invention is to simplify the design, expand the range, increase the intensity of stretching. For this purpose, the loading unit is made in the form of a water supply tank with a level regulator suspended from the reservoir cable and two flexible pipelines with adjusting edges and on / off valves connecting the tank with a water capacity and canalization, and two time relays are located in the control unit: filling reservoir and water level stabilization in it. FIG. Figure 1 shows a schematic diagram of a device for under spinal stretching; in fig. 2 is a schematic diagram of the control unit; in fig. 3 is a graph of load changes during the procedure. The device comprises a bath 1 with a non-movable inclined shield 2. And a movable platform 3 to which the patient is fixed, respectively, along the 4 and 5 themselves. The platform 3 is connected by a cable 6, slung over blocks 7 and. 8, with a reservoir 9, which is filled with water from a water supply tank 10, connected to a water supply system and equipped with a level float regulator 11. Overflow pipe 12 connects tank 10 with sewage. The metering pipe 13 is provided with an adjusting valve 14, a normally closed solenoid valve 15 and a rubber tip 16 that do not impede the movement of the reservoir 9. The drain pipe 17 is equipped with a rubber hose 18, a valve 19 and a valve 20. The solenoid valves 15 and 20 are the actuators of unit 21 -managing

The control unit contains a relay 22 for filling the tank with contacts 23, a relay for stabilizing the water level in the tank with contacts 25-27, intermediate relay 28 in the tank filling circuit with contacts 29.30, intermediate relay 31 in the tank emptying circuit 9 with contacts 32- 34, a button 35 for activating the tank filling circuit (i.e., turning on the increase in exhaust force), a button 36 for prematurely reducing the load, lamps 37-39, respectively signaling that the tank is full, that the water level in it is stabilized and that it is empty.

The device works as follows. The reservoir 9 is a variable-weight water weight capable of acting through the cable 6, blocks 7, 8, and c from 5 on the patient in both horizontal and vertical stretches. With horizontal stretching, the use of the underwater platform 3 makes it possible to most intensively affect the equal level calls if; place them between the fixed shield 2 and the platform 3. Thus, the frictional forces between the patient's body and both parts of the shield play a positive role, reducing the tensile force on the healthy part of the spine.

Assign the following procedure parameters:

Maximum force F, kg. Rise time tj, min Stabilization time t., Min. Time to reduce the load ty, mi Before starting the device, set the time t and t. using the set points of the relay 22 and 24 and the position of the adjusting valves 14 and 19 depending on the values of t (t and F. Then they press the button 35, the relay 28 is activated by opening the valve 15. This switches on the relay 22 and the lamp 37. After a time interval t KOHTact 23 closes by turning on relay 24

stabilization and the lamp 38, and contact 25 will immediately open, valve 15 will close, lamp 37 will go out, pej: e 22 will be de-energized. During the specified interval tg, load F ,, will be pulled out, after which contact 27 is closed and relay 31 .. with contact 34 opens valve 20 and lights the lamp 39. Water will begin to drain into the sewer during interval t, Contact 32 prepares the relay 24 circuit to a new cycle.

During the procedure, one or several cycles can be performed. At the moment of the start of a new cycle after pressing the button 35, the relay circuit 31 will be disconnected and the valve 20 will close simultaneously with the opening of the valve 15.

To abort the extrusion at any moment of the procedure, it is necessary to open the valve 19 as much as possible and press the button 36 to reduce the load prematurely.

Solenoid valves 15 and 20 can be placed in a dry room adjacent to the bathroom, as the only circuit elements that draw current.

The proposed device, simply and reliably, in terms of the likelihood of a jerk, makes it possible to increase the efficiency of stretching.
