The received information is displayed in numerical values on the screen, which allows you to assess the symmetry of the load distribution for the right and left parts of the user's body in order to make sure that the standing posture in the verticalizer is organized symmetrically, neutrally and gives an even load to both legs.

Description

The utility model relates to devices of the type of adjustable functional supports, intended to organize a safe and correct vertical position of a disabled person (child or adult), taking into account his physical condition and anthropometric data.

The proposed verticalizer allows smoothly giving the user a vertical position and giving an axial load to his body.

The verticalizer is suitable for use in most diagnoses that disrupt the functioning of the musculoskeletal system (for example, cerebral palsy, neuromuscular diseases, Spina Bifida, spinal and craniocerebral injuries, demyelinating diseases, genetic diseases, etc.).

The verticalizer allows both to maintain and develop existing skills and to improve the general condition of the body: to restore respiratory, digestive, excretory functions, blood circulation, to normalize muscle tone, to train physical endurance and the vestibular apparatus, it can also be used for the prevention or treatment of orthopedic complications. The presence in the verticalizer of a device for measuring the pressure of the user's feet on the supports allows to estimate the symmetry of the load distribution for the right and left parts of the body, since in many cases various orthopedic deformations do not allow to make sure with certainty that the user's standing posture in the verticalizer is organized symmetrically, neutrally and gives an even load to both legs. With regular use, this function of the device allows to dynamically monitor the user's condition and make timely changes to the verticalizer settings. Thus, thanks to the device for measuring the pressure of the user's feet in the verticalizer, the quality of the organized standing posture is improved, and the efficiency and safety of the verticalization process is increased.

The prior art discloses a standing support - a verticalizer with stepless adjustment of the angle of inclination (RU 201760 U1, class A61F 5/00, published on 11.01.2021), which comprises a metal frame with wheels, with a platform mounted on it, consisting of a stand made of a structural profile, on which are mounted: a footrest with foot holders, support modules for parts of the user's body: thigh and chest modules equipped with belts, an intermediate module, while it contains a stepless adjustment unit for the angle of inclination of the platform, represented by two lockable gas springs with a pedal.

The verticalizer in the front-back support configuration comprises a frame 1 on wheels 35, a gas shock absorber pedal 2, a guide arrow for adjusting the angle of inclination of the verticalizer 3, connected to the frame 1 by means of a corner 49, a gas shock absorber 4, a table height adjustment unit 5, a back and chest support height fastening and adjustment unit 6, a foot fastening unit 7, a knee joint support unit 8, a table frame 9, a table adjustment unit in longitudinal and angular positions 48, a back and chest support unit 10, a head support position adjustment unit 11, an anatomically adjustable head support unit 12, a handle 13, a pelvic support unit 14, a device for assessing the uniformity of foot pressure 29, a hip fastening unit 31, a table 34.

The verticalizer provides the ability to spread the user's legs. This is done by releasing screw 28 and deflecting pipe 15 to the desired angle from the vertical axis of the verticalizer. Also, pipe 15 provides additional (adjustable in the horizontal axis) lateral support for the pelvis 31.

The adjustment of the position of the foot fastening unit 7 is carried out by moving this unit along and around the pipe 15. The foot fastening unit 7 provides for precise adjustment of the position of the user's feet by adjusting the position of the boot 16 on plane A, for which purpose H-shaped grooves are provided in plane A. Fixation of the boot 16 in the desired position on plane A is ensured by tightening the screws 17.

The adjustment of the knee joint support unit 8 is also carried out by moving this unit along and around the pipe 15. The extension and displacement of the knee joint support cushions 30, as well as the setting of their angle, is carried out by fixing the clamps 18 and the screw 19.

The height of the back and chest support unit 10 is adjusted by fixing the pin-handle 20 at discrete points and an additional lock 21. The side support 22 is also adjusted in height using the lock 23 and in reach using screws 24.

The head support unit is adjusted in height using lock 25, in reach using lock 26 and in position in space using lock 27.

The device for assessing the uniformity of foot pressure 29 contains a left fixed base 40 and a right fixed base 41, rigidly connected, respectively, to two planes B of boots 16, which, in turn, are mounted on foot rests 39. The device for assessing the uniformity of foot pressure 29 is fastened to boots 16 by means of fastening elements. The left fixed base 40 and the right fixed base 41 are also connected, respectively, to the left movable platform 42 and the right movable platform 43 through fastening holes 44, located in several places and spaced along the edges of the movable platforms 42 and 43 and the fixed bases 40 and 41. The mobility of the platforms 42 and 43 is ensured by installing springs (not shown in the figure) between the left movable platform 42 and the left fixed base 40, as well as between the right movable platform 43 and the right fixed base 41. The travel of the springs is limited by the length of the fastening elements. Also, the device for assessing the uniformity of foot pressure 29 contains two force sensors (not shown in the figure), each of which is located between the left movable platform 42 and the left fixed base 40, as well as between the right movable platform 43 and the right fixed base 41. These sensors are metal frames that take on the force from the user's weight and limit the movement of platforms 42 and 43 in the direction of gravity when the user is on them. Another component of the device is the analyzing unit 47, which transmits information about the difference or equality of forces between the left movable platform 42 and the right movable platform 43 to the screen 46 via data transmission channels 45.

In the front-support configuration, the verticalizer comprises a frame 1 on wheels 35, a gas shock absorber pedal 2, a guide boom for adjusting the tilt angle of the verticalizer 3, connected to the frame 1 by means of a corner 49, a gas shock absorber 4, a unit for fastening and adjusting the height of the back and chest support 6, a unit for adjusting the table in longitudinal and angular positions 48, a unit for fastening the feet 7, a unit for supporting the knee joint 8, a unit for supporting the pelvis 14, a unit for supporting the back and chest 10, a handle 13, a device for assessing the uniformity of foot pressure 29.

The front-support configuration of the verticalizer is transformed from the front-back support configuration by removing the anatomically adjustable head support unit 12 from it, installing an additional pillow 32 and an inguinal crossbar 33 to the pelvic support unit 14 of the verticalizer in the front-back support configuration, rearranging the table 34 with the handle 13 and turning the boot 16 by 180° (for which an additional H-shaped groove is provided in plane A).

The rearrangement of table 34 is carried out using part 36, which is installed in the standard place of table 34 of the verticalizer in the front-rear support configuration while maintaining all adjustments.

All verticalizer adjustments in the front-rear support and front support configurations are identical.

The proposed verticalizer in the front-back support configuration operates as follows.

The initial position for the verticalizer is the position in which the angle between the horizontal axis 37, parallel to the surface on which the verticalizer is located, and the vertical axis of symmetry of the verticalizer 38 is 0°. In the initial position of the verticalizer, the user is placed in it with his back to the cushions (not shown in the figure) on the attachment and support units, and is fixed with belts (not shown in the figure): the feet are fixed in the foot attachment unit 7, the user's body is fixed in the hip attachment unit 31 and the back and chest support unit 10. The knees are fixed in the knee joint support unit 8. After fixing the entire body, the user is gradually verticalized by pressing the gas shock absorber pedal 2. Pressing unlocks the gas shock absorber 4, freeing the movement of the components of the guide boom for adjusting the tilt angle of the verticalizer 3. In this way, the angle between the horizontal axis 37 and the vertical axis of symmetry of the verticalizer 38 will increase from 0 to 90°, which will allow the user to take a completely vertical position. If necessary, the user can deviate 20° forward (in this case, the angle between the horizontal axis 37 and the vertical axis of symmetry of the verticalizer 38 will be 110°). During the verticalization process, the user's body is supported in the following places: feet, knees, pelvis, back and head. All supports, except for the pelvic support unit 14, have adjustments for more precise adjustment to the individual characteristics of the user. In the process of verticalization, a continuous process of assessing the uniformity of the user's foot pressure also occurs with the help of the device for assessing the uniformity of foot pressure 29. The user's feet are located in the center of the movable platforms 42 and 43 of the device for assessing the uniformity of foot pressure 29. The user presses with his weight on the movable platforms 42 and 43, which, in turn, press on the force sensors inside the device for assessing the uniformity of foot pressure 29, and through data transmission channels 45 transmit data to the analyzing unit 47, in which the process of comparing the received data from the left and right movable platforms 42 and 43 occurs and transmits to the screen 46 information about the difference or equality of forces between the left movable platform 42 and the right movable platform 43.

The proposed verticalizer in the front support configuration operates as follows.

The initial position for the verticalizer is the position in which the angle between the horizontal axis 37, parallel to the surface on which the verticalizer is located, and the vertical axis of symmetry of the verticalizer 38 is 0°, the anatomically adjustable head support unit 12 is removed and all necessary processes of transformation from the anterior-posterior support configuration to the anterior support, described earlier, have been preliminarily carried out. In the initial position of the verticalizer, the user is placed in it with his stomach to the pillows on the attachment and support units, and is fixed with belts: in the foot attachment unit 7, the feet are fixed, in the hip attachment unit 31 and the back and chest support unit 10 - the user's body. In the knee joint support unit 8, the knees are fixed. After fixing the entire body, the user is gradually verticalized by pressing the gas shock absorber pedal 2. Pressing unlocks the gas shock absorber 4, freeing the movement of the components of the guide boom for adjusting the tilt angle of the verticalizer 3. In this way, the angle between the horizontal axis 37 and the vertical axis of symmetry of the verticalizer 38 will increase from 0 to 90°, which will allow the user to take a completely vertical position. If necessary, the user can deviate back by 20° (in this case, the angle between the horizontal axis 37 and the vertical axis of symmetry of the verticalizer 38 will be 110°). During the verticalization process, the user's body is supported in the following places: feet, knees, hips and stomach. The pelvic area is fixed with the help of an additional pillow 32 and an inguinal crossbar 33 installed to the pelvic support unit 14. During the process of anterior verticalization, a continuous process of assessing the uniformity of the pressure of the user's feet also occurs with the help of a device for assessing the uniformity of the pressure of the feet 29. The user's feet are located in the center of the movable platforms 42 and 43 of the device for assessing the uniformity of the pressure of the feet 29. With his weight, the user presses on the movable platforms 42 and 43, which, in turn, press on the force sensors inside the device for assessing the uniformity of the pressure of the feet 29, and through data transmission channels 45 transmit data to the analyzing unit 47, in which the process of comparing the received data from the left and right movable platforms 42 and 43 takes place and transmits information to the screen 46 about the difference or equality of the forces between the left movable platform 42 and the right movable platform 43.
