Description

Multifunctional wheelchair

DESCRIPTION

The invention relates to individual vehicles specifically designed for disabled or people with disabilities in movement, mainly to wheelchairs with devices to facilitate rising, sitting, lifting, and also to move a disabled person from a wheelchair and back to a chair - a wheelchair, using various suspensions and accessories, both independently and with the help of an assistant [A61G 5/00, A61G 5/14].

There is a wide variety of wheelchairs with manual, electric and mixed drive:

DR-

However, the presented wheelchairs do not have devices ensuring the movement of disabled people into a wheelchair.

Known functional stroller for patients, containing a base mounted on wheels, mounted on the base of a vertical strut with a drive carriage, a bracket on one end of which a seat is fixed, a pivoting mechanism in the form of a shaft with a handle, two wheels mounted on one shaft and equipped with a chain drive and a handle. The stroller is designed for self-care of patients and can be used by patients with one arm (SU AS N21316673 A1 class A 61 G 7/10, 5/4 1987).

This device expands the possibilities for self-service, however, it is cumbersome, has limited maneuverability, especially in small-sized apartments, and does not provide the movement of greatly weakened people using suspensions.

Known elevator for moving patients, containing a base mounted on wheels, mounted on the base and having a rectangular cross-section, a vertical strut with a drive carriage, bearing bracket, on one the end of which the seat is fixed, and the handle for controlling movement, is additionally equipped with a screw jack connecting the other end of the bracket to the rack, and the carriage with the drive is located in the cavity of the rack and is pivotally connected to the bracket, while the carriage is mounted on the wheel system, including the upper and a lower pair of wheels mounted on opposite sides of the rack axis and in contact with its two opposite supporting walls, and an additional wheel mounted between the upper and lower pair of wheels and in contact with with other opposing support walls, and the handle is fixed to the stand. In this case, the carriage drive is a hydraulic jack. (RU 33500 U1 A61G3 / 06 10.27.2003).

This device does not have the functions of a wheelchair and allows you to lift and move the disabled and people with disabilities in motion only with the help of an assistant. The device is accepted as the closest analogue.

The task to which the claimed invention is directed is to improve the consumer properties of a wheelchair by expanding its functionality.

The technical result is the provision of opportunities for:

- facilitating getting up or sitting in a wheelchair and moving in it both indoors and outside;

- moving from a wheelchair to a chair, to a bathtub, to a toilet bowl or back to a wheelchair;

- lifting a physically weakened person from a lying position to a sitting or vertical position or lowering him to his original position;

- lifting a bed patient over the bed to change bedding, examining the patient’s body from the back, as well as for conducting sanitary-hygienic procedures

DUR

At the same time, getting up, sitting down, moving from a wheelchair and back, raising, lowering over a bed or moving indoors and outdoors using a wheelchair with a lift can be carried out independently. so with the help of an assistant.

The implementation of the invention

The multifunctional wheelchair contains a base 3 mounted on wheels 1 and 2, mounted on the base and having a rectangular cross-section, a vertical strut 4 with a handle 5 for moving the wheelchair and with a vertical carriage 6 in the cavity of the strut 4 with a drive 7 carrying 7 - a single boom 8 and mounted on a wheel system, including upper and lower groups of support wheels 9, located on opposite sides of the axis of the rack, while at least one of the wheels 1 and 2 mounted on the base is - duschim, also designated based on the frame 10 with seat 11 and on the boom on ustanovle- longitudinal carriage 12, connected by a hinge 13 with a hanger 14.

The base is made collapsible and consisting of a transverse beam 15 and two longitudinal cantilever supports 16.

The upright is made with a square cross section.

The pusher 17 and part of the drive 7 of the vertical carriage are placed in its cavity, and the pusher is pivotally connected with the upper end to the carriage.

The drive of the vertical carriage is made electric.

The boom is pivotally connected to the upper end of the vertical carriage to ensure that the boom rotates around the horizontal axis back to a vertical position.

The support wheels 9 are mounted on a vertical strut and in contact with two opposite walls of the vertical carriage.

Quality bearings were used as supporting wheels of the vertical carriage.

The support wheels of the vertical carriage in each group of wheels are self-mounted to equalize the loads on them.

The drive wheels are made with a manual drive. For convenience, when the person is turned around on a suspension, the frame 10 with the seat 11 is made folding.

To raise and move a disabled person, the seat 11 is quick-detachable and connected by slings 18 through a suspension 14 and a hinge 13 with a carriage 12.

The seat can be made with a removable segment for the toilet.

The longitudinal carriage 12 is made with an electric drive 19 and a helical gear 20.

The longitudinal carriage 12 is made with self-aligning wheels 21 for balancing the loads on them.

As the wheels 21 in the longitudinal carriage 12, rolling bearings are used.

To raise a disabled person, depending on his particular physical condition, a seat 11 with slings 18, or a belt 22 with slings of a belt 23 or a frame 24 with straps 25 attached to the slings 18 is attached to the suspension 14.

The swivel connection between the longitudinal carriage 12 and the suspension provides the suspension 14 to rotate relative to the vertical axis by a full revolution in each of two directions.

The footboard 26 is made movable under the seat.

The back 27 is mounted on a rack with adjustable height.

The armrests 28 are mounted on a rack with adjustable height.

Use a multi-functional wheelchair as follows.

The removable seat 11 is used to move from a wheelchair to a chair, to a bathtub, to a toilet bowl or back to a wheelchair. When using a removable seat

11, the wheelchair is mounted so that the carriage 12 with the suspension 14, located at the end of the boom 8, is located above the head of the disabled person. The removed seat 11, free of slings 18, is placed under a disabled person sitting on a chair or bed, or he, if this is possible, moves to the seat. Then slings 18 are attached to the seat, for example by means of carabiners or similar devices. In this case, the slings are connected to the suspension 14. Then, using the drive 7, the vertical carriage b together with the boom 8, the suspension 14 and the seat 11 with the disabled person is raised to the required height. After that, using the drive 19, the longitudinal carriage

12 together with the suspension and the seat are moved in the direction of the vertical strut 4 a distance sufficient to turn the seat with the disabled person half a turn. After the turn, the horizontal carriage 12 is continued to be moved in the direction of the vertical strut 4 to the corresponding position above the frame 10. Next, the vertical carriage 6 with the boom seat and the disabled person is lowered to align the seat 11 with the seats on the frame 10.

Belt 22 is preferably used to facilitate getting up or sitting in a wheelchair, to facilitate moving from a wheelchair to a chair, to a bathtub, toilets or back to a wheelchair and to lift a physically weakened person from a lying position to a sitting or vertical or lowering him to the starting position. The belt is fixed at the level of the waist or chest, the slings of the belt 23 are attached to the suspension. Lifting and moving a disabled person is carried out using vertical and horizontal carriages, driven by appropriate drives. Half a turn is carried out as when using the removable seat 11.

Moving in a multifunctional wheelchair with a lift is essentially the same as moving in a conventional wheelchair without a lift.

A frame 24 with straps 25, mounted on slings 18, is used to lift a patient lying on top of the bed with the aim of changing bedding, examining the patient's body from the back, and also for carrying out sanitary and hygienic procedures. The frame is placed on the bed with the patient and the belts 25 are subsequently pulled under it. With the help of slings 18 and carabiners, the frame is connected to the suspension 14. The frame is raised and lowered with the patient by the corresponding movement of the vertical carriage.
