Disclosure of utility model.

While sitting a patient with spinal injuries, it is necessary to provide the patient with additional support to reduce body weight on the spine.

Adjustable unloading and correction of the spine in the sitting position is performed using a structure of two spring-loaded supports (Fig. 2) installed in the axillary part of the patient (Fig. 1).

The force effect of each support on the axillary part is regulated separately, which allows for correction, including for curvature of the spine in a certain direction. The degree of unloading of the spine when sitting is based on the recommendations of a medical specialist.

The proposed model "Device for correction and adjustable unloading of the spine when sitting" is based on the task of developing a design that will provide the following technical result: - providing the possibility of regulating the unloading of the spine when sitting based on human physiological data.

To solve this problem, adjustable unloading of the spine in the sitting position is performed by two symmetrical devices consisting of axillary pads (Fig. 2, item 10) mounted on movable axillary supports (Fig. 2, item 11). The movable movable support (Fig. 2, item 11) is installed inside the main rack (Fig. 2, item 12) and is spring-loaded to dampen the user's movement with a shock-absorbing spring (Fig. 3, item 15).

The damping spring rests on a support washer (Fig. 3, item 16) installed inside the main rack (Fig. 2, item 12).

The support washer of the shock-absorbing spring moves in the groove (Fig. 2, pos. 8) of the main rack (Fig. 2, pos. 12) and is fixed with a screw lamb (Fig. 3, pos. 8) to set the adjustable height of the movable axillary support (Fig. 3, item 11) according to the height of the user and the creation of an adjustable unloading of the spine.

Between the movable axillary support (Fig. 3, pos. 11) and the support washer of the damping spring (Fig. 3, pos. 16) there is a certain distance, which is intended for cushioning and subsequent hard stop of the movable axillary support (Fig. 3, pos. 11 ) when the pressure of the user's weight on the device is exceeded. The main stand (Fig. 3, pos. 12) is rigidly mounted on the support ball (Fig. 3, pos. 7) to give the main stand some movement of the support ball when the user moves forward, backward, right, left while sitting. At this time, the force of the adjustable unloading of the spine remains approximately constant, as previously established by the specialist.

The support ball (Fig. 3, item 7) is installed in the socket of the base for the support ball (Fig. 3, item 3) of the main rack (Fig. 3, item 12) and has the possibility of a slight deviation along the circular horizontal plane. The base for the support ball (Fig. 3, pos. 3) moves in the grooves of the profile guide to move the axillary supports (Fig. 3, pos. 2) and is fixed after convenient installation after moving with a screw lamb to secure the axillary structure (Fig. 2, pos. 13).

The support ball (Fig. 3, pos. 7) is fixed with a certain force in the socket of the base for the support ball of the main rack (Fig. 3, pos. 3) by the pressure plate of the support ball (Fig. 3, pos. 4).

The degree of clamping of the support ball (Fig. 3, pos. 7) by the pressure plate of the support ball (Fig. 3, pos. 4) is set by the screw lamb for adjusting the clamp of the support ball (Fig. 2, pos. 6) and the spring that creates the necessary force for rotation support ball (Fig. 2, pos. 5) with some movement of the user.

Two profile guides for moving the axillary supports (Fig. 2, item 2) are installed on the platform on which the device is assembled (Fig. 2, item 1).
