RU239414U1 - A verticalizer for a disabled person to adopt a safe and correct position, taking into account his physical condition and anthropometric data - Google Patents

Abstract

This utility model relates to adjustable functional supports designed to ensure a safe and correct vertical position for a disabled person (child or adult), taking into account their physical condition and anthropometric data. The proposed verticalizer has a rotary-retractable table on easily removable fasteners, allowing for its removal and installation without the use of tools, and also eliminating the need to remove it when placing the user in or removing the verticalizer. The technical result of this utility model is improved ergonomics. This technical result is achieved by the verticalizer having a front-back support, transforming into a front-support device, and comprising a rotary-retractable table on easily removable fasteners, allowing for the fastening elements to be disconnected with one hand, without the use of tools. The table is rotated and retracted by disengaging the first easily removable mount, for example, by disengaging the clamped portion of the table with internal cones from the support tube by loosening the threaded element with a handle, and rotating the table around the axis of the second easily removable mount. This eliminates the need to remove the table when placing the user in the verticalizer or when removing them from the verticalizer. Repositioning the table when transforming the verticalizer from a front-back configuration to a front-support configuration is accomplished without tools, as the easily removable mount is a unit, one part of which is mounted on the table frame and the other on the support tube. The unit on the support tube secures the counterpart located on the table frame, or vice versa: the counterpart located on the table frame secures the unit on the support tube.

Description

This utility model pertains to adjustable functional supports designed to ensure a safe and correct upright position for a disabled person (child or adult), taking into account their physical condition and anthropometric data. The proposed verticalizer allows for smooth vertical positioning of the user and the application of axial load to their body. The verticalizer is suitable for use in most conditions affecting the musculoskeletal system (e.g., cerebral palsy, neuromuscular disorders, spina bifida, spinal and traumatic brain injuries, demyelinating diseases, genetic disorders, etc.). The verticalizer allows for the maintenance and development of existing skills and the improvement of overall well-being: it restores respiratory, digestive, and excretory functions, as well as circulation, normalizes muscle tone, trains physical endurance and the vestibular system. It can also be used for the prevention or treatment of orthopedic complications. The versatility of the proposed verticalizer in terms of configuration options (anterior-posterior and anterior support) allows for changing the type of support depending on the user's physical condition (in some cases, anterior-posterior support configuration is required, in others, anterior support), which allows for its effective use both at home and in medical institutions.

A standing support is known - a verticalizer with a lateral support unit (RU 201725 U1, class A61F 5/37, published on December 29, 2020), which comprises a metal frame with wheels, on which a post made of a structural profile is mounted, on which are mounted: an electric actuator controlled by a wired remote control, a footrest with foot holders and sequentially connected support modules for parts of the user's body: a hip module, an intermediate module, a chest module. A lateral support unit is installed on the hip module and chest module in the form of adjustable lateral limiters with slots in which belts are installed, configured to be adjustable in length. The support includes a headrest. The support modules contain pillows that are made removable.

The disadvantages of this well-known utility model include limited user-specific adjustments and the inclusion of a footrest, which prevents leg abduction and knee pads. Furthermore, the straps are only secured at two levels, which does not ensure adequate safety. Furthermore, there is no anatomically shaped headrest or table, and the footrest cannot be adjusted separately for each leg.

A multifunctional standing support (RU 207012 U1, class A61F 5/37, published 06.10.2021) is also known, which includes a metal base with wheels with brakes. On the base are a pedestal with a lifting mechanism and a rack with sequentially arranged support modules for parts of the user's body: a headrest, adjustable in height due to legs immersed in the chest module, a thigh module, rods with the ability to abduct up to 30 degrees to support the legs with knee pads and foot holders installed with the ability to move along the rods and adjust the position. A lateral support unit in the form of adjustable lateral stops is installed on the chest module and the thigh module, fixing the belt at the level of the thigh module. There is a table adjustable in depth, height, and angle of inclination. An electric actuator controlled by a wired remote control is installed as a lifting mechanism. A platform is attached to a support frame consisting of two parallel vertical elements. A lever extends downward from the center of the frame's underside, interacting with an actuator rod that extends between the vertical elements of the support frame. The hip module is attached to the rotating support frame. An intermediate module with an internal frame is also installed on it, followed by a chest module with an internal frame and a headrest. The modules and headrest have removable soft components. The headrest and chest modules have legs. The hip, intermediate, and chest modules consist of two walls, a front and a back, which are bolted to the frames. The headrest consists of a single wall, and the chest module is covered at the top by a bar with an opening for the headrest legs. Between the walls of the modules, the internal frames feature vertical channels for installing the legs, allowing for adjustable footrest depth. Horizontal tubes are also provided for installing adjustable side restraints, which are further equipped with adjustable straps on the chest and hip modules. An abductor is installed, adjustable in height and extendable in size. When positioning the user on their stomach or chest, the headrest is removed, a removable soft pad is attached to the bar covering the top of the chest module, the sandals are rotated 180 degrees on the footrest pad, and the tray is repositioned to the appropriate side of the support, according to the child's position.

A disadvantage of the well-known utility model is the lack of a sufficient number of modules for fixing the user, namely, that in the forward support position of the user (on the stomach and chest) there is no additional cushion and groin crossbar, as well as insufficient ergonomics, which consists in the fact that in order to remove the user from the standing support or to place him in the standing support, it is necessary to remove the table.

The RT RTX18 children's front-back support stander with leg abduction (https://med-ob.ru/detskie-vertikalizatory/c-razvedeniem-nog/vertikalizator-dvuhopornyi-s-razvedeniem-nog-rt-rtx18) is a well-known device. It features front and back support and is equipped with multiple auxiliary supports. Thanks to its multiple support points, the device provides reliable and stable support, allowing children to lean on the stander with their back, chest, or abdomen. One of the key features of the RTX-18 model is the ability to independently abduct each leg. This allows for a personalized approach to rehabilitation, which is especially useful when correction or development of specific motor skills is needed. The device effectively supports the feet, knees, and hips, which in turn promotes even load distribution and reduces stress on the joints. All supporting elements, such as knee and foot supports, are individually selected for each patient, thereby taking into account the child's unique anatomy and needs.

The disadvantages of the known technical solution include significant limitations in terms of the anthropological characteristics of the user (for example, the user height limit of 155 cm does not allow the verticalizer to be used by most adult users), as well as insufficient ergonomics, namely the impossibility of removing the table from the verticalizer when transferring the verticalizer from the rear-support position to the front-support position without the use of tools (Ax bolts are used to secure the table).

The ExoStand front-back support (verticalizer) is also known from the prior art (https://exo-technology.ru/product/ekzostend-main/). This front-back support (verticalizer) is designed for standing with isolated leg abduction for children who require static standing. The stander is supplied with an anterior-posterior support configuration, allowing for use with the desired support. The support allows for individual hip abduction angle adjustments from 0 to 30 degrees for each leg. The angle of verticalization is smoothly adjustable, from 90 to -15 degrees. The stander's size range is designed for users with a height of 70 to 180 cm.

The disadvantages of the well-known front-back stand (standing frame) include the small user height ranges within each size range: there are only four sizes, and within each size, the minimum to maximum user height range is 30 cm, which, given a child's growth, necessitates frequent replacement. Furthermore, the well-known stand is not ergonomically sound: the table must be removed to remove the user from the standing frame or to place them in the standing frame.

The LIW COCO anterior-posterior support verticalizer with leg abduction is also known from the prior art (https://supportshop.ru/vertikalizator-dlya-detey-dcp/vertikalizator-staticheskiy/vertikalizator-s-razvedeniem-nog-liw-coco?ysclid=mdn4c5uqwh316050956). The device allows for the hip abduction angle to be set independently for the left and right legs within a range of 0–30°. This feature allows for the legs to be adjusted in the frontal plane to correctly position the femoral head within the joint. It is recommended for patients at risk of hip displacement. The device can measure the verticalization angle from +90° to -15°. This hip abduction angle measurement function provides the therapist with a precise device for safe verticalization.

The disadvantages of the known technical solution include significant limitations in terms of the anthropological characteristics of the user (for example, the user height limit of 150 cm does not allow the verticalizer to be used by most adult users), as well as insufficient ergonomics, which consists in the fact that in order to remove the user from the verticalizer or to place him in the verticalizer, the table must be removed.

The technical result that this utility model is aimed at is improving ergonomics.

The technical result is achieved by a verticalizer designed for a disabled person to adopt a safe and correct position, taking into account their physical condition and anthropometric data. It features an anterior-posterior support system, convertible to an anterior support system, and a rotating-retractable table on easily removable fasteners that allow for one-handed, tool-free disengagement. The table rotates and retracts by disengaging the first easily removable fastener, for example, by disengaging the clamped portion of the table with internal cones from the supporting tube by loosening a threaded element with a handle, and by rotating the table around the axis of the second easily removable fastener. This eliminates the need to remove the table when placing the user in or removing them from the verticalizer. Repositioning the table during the verticalizer's transformation from an anterior-posterior support configuration to an anterior support configuration is accomplished without tools, as the easily removable fastener is a unit, one part of which is mounted on the table frame and the other on the supporting tube. A unit on the support tube secures a counter-piece located on the table frame, or vice versa: a counter-piece located on the table frame secures the unit to the support tube. Securement can be accomplished by tightening or crimping using the following elements: a threaded element with a handle, an eccentric element, or a quick-release coupling.

According to a non-limiting embodiment of the utility model, the verticalizer in the front-rear support configuration comprises a frame 1 on wheels 15, a gas shock absorber pedal 2, a support boom 3 connected to the frame 1 by means of a corner 16, a gas shock absorber 4, a table height adjustment unit 5, a back and chest attachment height adjustment unit 6, a foot attachment unit 7, a knee joint support unit 8, a table frame 9, a table angular position adjustment unit 17, a table longitudinal position adjustment unit 45, a back and chest attachment unit 10, a back and chest lateral support unit 20, a head support position adjustment unit 11, an anatomically adjustable head support unit 12, a handle 13, a pelvic attachment unit 14, a hip lateral support unit 18, and a table 19.

The verticalizer allows the user's legs to be adjusted 30 ^° apart, independently for the left and right legs. This is accomplished by loosening the screw with handle 47 and tilting the tube 21 to the desired angle from the verticalizer's vertical axis, according to the angle scale 24. Tube 21 also features an additional (adjustable horizontal axis) lateral thigh support unit 18.

The position of the foot fastening unit 7 is adjusted by moving this unit along and around the pipe 21 in height and angle, which is accomplished by loosening the screw with handle 44. The foot fastening unit 7 also provides for precise adjustment of the user's foot position by adjusting the position of the boot 25 on plane A , for which purpose H-shaped grooves are provided in plane A. Fixation of the boot 25 in the desired position on plane A is ensured by tightening the locking screw 46.

The adjustment of the knee joint support unit 8 is also carried out by moving this unit along and around the pipe 21. The extension and displacement of the knee joint support cushions 26, as well as the setting of their angle, is carried out by fixing the locking screw 27 and screw 28.

The height of the back and chest support unit 10 is adjusted by fixing the pin-handle 29 at discrete points and an additional lock 30. The side support 20 is also adjusted in height using a lock 31 and in reach using screws 32.

The head support unit is adjusted in height using lock 33, in reach using lock 34 and in position in space using lock 35.

Table 19 is a retractable table with easily removable fasteners 36 and 37, allowing the fastener elements to be disconnected with one hand and without the use of tools. The rotation and retraction of table 19 are accomplished by disconnecting the clamping cone 41 of the supporting tube 39 of the first easily removable fastener 36 from the clamped portion of the table with the internal cones 38 by loosening the threaded element with handle 40, and rotating table 19 around the axis of the second easily removable fastener 37.

In the front-support configuration, the verticalizer comprises a frame 1 on wheels 15, 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 16, a gas shock absorber 4, a unit for adjusting the height of the back and chest fastening unit 6, a unit for adjusting the table in an angular position 17, a unit for adjusting the table in a longitudinal position 45, a foot fastening unit 7, a knee joint support unit 8, a pelvic fastening unit 14, a back and chest fastening unit 10, a handle 13, a hip lateral support unit 18, a table 19, a table frame 9, a back and chest lateral support unit 20.

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 22 and an inguinal crossbar 23 to the pelvic attachment unit 14 of the verticalizer in the front-back support configuration, rearranging the table 19 with the handle 13 and turning the boot 25 by 180° (for which an additional H-shaped groove is provided in plane A ).

The rearrangement of table 19 during the transformation of the verticalizer from the front-rear support configuration to the front support configuration is carried out without the use of a tool, since each easily removable fastening 36 and 37 is a unit, one part of which is located on the frame of table 9, and the second part is on the supporting pipe 39. The clamping cone 41 of the supporting pipe 39 is disconnected from the clamped part of the table with internal cones 38, located on the frame of table 9, and the disconnection is carried out by loosening the threaded element with handle 40.

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 of the verticalizer is the position in which the angle between the horizontal axis 42, parallel to the surface on which the verticalizer is located, and the vertical axis of symmetry of the verticalizer 43 is 0°. In the initial position of the verticalizer, the table 19 is moved away in such a way that it does not interfere with the placement of the user in the verticalizer, this occurs as follows: the threaded element with the handle 40 is loosened until the clamping cone 41 of the supporting pipe 39 stops fixing the clamped part of the table with the internal cones 38, located on the frame of the table 9. In this way, one of the easily removable fasteners 36 or 37 is disconnected, which allows the table 19 to be completely moved aside. In the initial position of the verticalizer, the user is placed in it with his back to the back and chest attachment unit 10 and the pelvic attachment unit 14 and secured with belts (not shown in the figure): the feet are secured in the foot attachment unit 7, and the user's body is secured in the pelvic attachment unit 14 and in the back and chest attachment unit 10. The knee joint is secured on both sides in the knee joint support unit 8. After the entire body is secured, 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 component parts of the support boom 3. This will increase the angle between the horizontal axis 42 and the vertical axis of symmetry of the verticalizer 43 from 0° to 90°, which will allow the user to assume a completely vertical position. If necessary, the user can be tilted forward by 20° (in which case the angle between the horizontal axis 42 and the vertical axis of symmetry of the verticalizer 43 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 attachment unit 14, are adjustable for more precise adjustment to the individual characteristics of the user. After placing the user in a horizontal position in the verticalizer and fixing it, the previously moved table 19 is returned to the position in front of the user and fixed by connecting the previously disconnected elements of one of the easily removable fasteners 36 or 37 with one hand without the use of a tool, namely, by the fact that the clamped part of the table with internal cones 38 is fixed by clamping cones 41 of the supporting pipe 39 by tightening the threaded element with the handle 40.

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

The verticalizer's initial position is one in which the angle between horizontal axis 42, parallel to the surface on which the verticalizer is positioned, and vertical axis 43 of symmetry of the verticalizer is 0°. The anatomically adjustable head support unit 12 has been removed, and all necessary transformation processes from the anterior-posterior support configuration to the anterior support configuration, as described previously, have been completed. In the initial position of the verticalizer, the user is placed with their stomach against the pads on the attachment and support units and secured with straps: the feet are secured in the foot attachment unit 7, the pelvic attachment unit 14, and the back and chest attachment unit 10 are used for the user's body. The knees are secured in the knee joint support unit 8. After the entire body is stabilized, the user is gradually verticalized by pressing gas shock absorber pedal 2. Pressing this pedal unlocks gas shock absorber 4, freeing the movement of the component parts of support boom 3. This increases the angle between horizontal axis 42 and vertical axis of symmetry of the verticalizer 43 from 0° to 90°, allowing the user to assume a fully vertical position. If necessary, the user can lean back 20° (in this case, the angle between horizontal axis 42 and vertical axis of symmetry of the verticalizer 43 will be 110°). During verticalization, with the verticalizer in the front-support configuration, the user's body is supported by the feet, knees, hips, and abdomen. The pelvic region is stabilized using an additional cushion 22 and a groin crossbar 23, mounted to the pelvic attachment unit 14.
