Description

This invention relates to medical equipment for underwater spinal stretching.

Installations for underwater horizontal stretching of the spine are known, comprising a bath, pelvic and chest sleeves, a cable and blocks. However, these units do not provide automatic dosing of the stretching force, and they do not allow visual control over the course of the stretching process.

The proposed installation differs from the known ones in that it is equipped with a time relay, a pointer device with a scale graduated in units of force, and an electric actuator connected to the pelvic sleeve by means of a cable. The latter is equipped with a spring and a dynamometer interacting with a time relay.

FIG. 1 shows a diagram of the proposed installation; in fig. 2 - installation control panel.

The apparatus comprises a bath 1, in which the patient is placed after filling it with water. The chest sleeve 2 is attached to the head of the bath on the throat. The pelvic sleeve 3 is connected to the electric drive 5 through the hummocks and blocks 4. The cables are equipped with a spring 6 and a dynamometer 7 that interacts with the time relay 8. Power Stretch

controlled by a switch instrument 9 calibrated in units of force (e.g., kg). The installation works as follows.

After the pelvic and thoracic liners (bodices) are laid on the patient and placed on a traction table or a special shield and bath, the metal cables from the installation for stretching through the block system are attached to the rings (lids) of the pelvic shells. The installation for automatic stretching is set by the stretching program in accordance with the doctor's prescription, namely the toggle switches 10 set the required

the magnitude of the stretching force (the scale of loads can be graduated, for example, from 0 to 50 kg).

In order to ensure that any given value of the stretching force is reached, a certain amount of electric current, measured by a voltmeter 12, is applied to the installation motor 11 for 5 minutes.

For the convenience of the physician, table 13 can be applied to the installation console according to the stretching force and the applied voltage.

motor drive //. The voltage is set by the handle 14.

By pressing the 15 ”button, the electric motor // is started, which, through the gearbox 16, transmits rotational movement to the worm shaft 17. A worm nut 18 moves through the worm shaft, to which an exhaust mechanism cable is attached via amortization spring 6 and through dynamometer 7. Upon reaching a predetermined exhaust force, the dynamometer 7 and the time relay 8 automatically stop the operation of the electric motor 11 and switch on the time relay for the required time interval of the specified maximum load. After the time interval has elapsed, the time switch automatically switches the motor back, and the load or the pull force is smoothly removed to zero within 5 minutes.

 - If for any reason it is necessary to reduce the stretching force, the operator pressing the button 19 on the control panel turns on the electric motor and reduces the stretching force to the desired value or within a few minutes (if desired and necessary) removes the stretch to zero.

The stretching force can be reduced or completely removed by the patient himself by pressing the lever 20 located at his hand.

Subject invention

An installation for underwater horizontal stretching of the spine, comprising a bath, pelvic and chest sleeves, a cable and blocks, characterized in that, in order to automatically dispense the stretching force over time and provide visual control of the process, a time relay, a dial gauge and the electric drive connected by means of a cable with a pelvic sleeve, the cable is equipped with a spring and a dynamometer that interacts with a time relay, and the scale of the dial instrument, for example a voltmeter, is calibrated in units of force. ; 3 20. /
