Description

The utility model relates to individual vehicles specifically designed for disabled or sick people with limited mobility, mainly to lifts with devices for moving bedridden patients using an assistant [A61G 5/00, A61G 5/14].

Depending on the suspensions and fixtures used, it can be used to raise, lower and move to a certain distance both bedridden patients, the overturning of which is contraindicated for medical reasons, as well as disabled people with impaired musculoskeletal system functions.

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, a support bracket, a seat is fixed at one end of it, and a handle for controlling movement, additionally equipped with a screw jack connecting the other end bracket with a rack, and the carriage with the drive is placed in the cavity of the rack and pivotally connected to the bracket, while the carriage is mounted on a system of wheels, including rhnyuyu and lower pair of wheels mounted on opposite sides of the axis of the strut and in contact with its two opposite support walls and the additional wheel is mounted between the upper and lower pair of wheels and contacting with the other two opposed support walls, and the handle is fixed to the rack. In this case, the carriage drive is a hydraulic jack. (RU 33500 U1, A61G 3/06, publ.: 10.27.2003). This device is cumbersome and structurally complex, has a lot of weight.

The device is oversized, weakly stable, may not pass through narrow doorways. A disadvantage of the solution is also that the lift cannot be used for bedridden patients, whose overturning is contraindicated for medical reasons.

The closest analogue is the GOLVO type hoist [http://biomir21.ru/?id=143&cat=16; http://biomir21.ru/img_cat/img_422.tif], publ.: November 2014. The solution describes a lift for moving bedridden patients, made on a movable support, containing a base mounted on wheels, mounted on a base and having a rectangular cross section of a vertical strut , suspension for a bed patient, contains an arrow; to the rack are attached two supports wide apart by width, at the ends of which wheels are mounted, a frame for the bed patient is fixed to the end of the boom, made of a rectangular shape with straps fixed on opposite sides of the frame. The disadvantage of this solution is that the lift cannot be used for bedridden patients, whose overturning is contraindicated for medical reasons. The lift is bulky and heavy.

The problem to which the claimed solution is directed is to eliminate the disadvantages of the prototype.

The technical result is the provision of the possibility of using a lift for raising and lowering bedridden patients, whose turning over is contraindicated for medical reasons.

The specified technical result is achieved due to the fact that the claimed lift for moving bedridden patients, performed on a movable support, containing a base mounted on wheels, mounted on a base and having a rectangular cross-section, a vertical rack, a suspension for a bed patient, contains an arrow; two supports are spread out across the width of the support, the wheels are mounted at the ends of the wheels, a frame for the bed patient is fixed to the end of the boom, made of a rectangular shape with straps fixed on opposite sides of the frame, characterized in that it contains a hydraulic cylinder that is pivotally connected to the rack and boom ; an arm is movably connected to the boom, into which a beam is inserted, made with the possibility of changing the position and subsequent fastening with locking screws; using carabiners, eye nuts and a sling, the frame is connected to the beam; laces are attached to the end of belts that have special holes for this, the function of which is to pull the belts under the patient.

The laces are made of material that does not irritate or damage the human skin when they are in direct contact with it for a long time or pull the laces under the human body, preferably from thin soft cotton threads. The two rear wheels preferably have brakes.

Two eye-nuts are fixed to the beam, which are a ring with a cylindrical thickening in one part of the ring, in the center of which passes a threaded hole, and four of the same eye-nuts are mounted on the frame.

The utility model is illustrated by drawings: FIG. 1 - FIG. 6.

Utility Model Implementation

The hoist frame is made of steel profile, equipped with a hydraulic cylinder with a built-in pump and self-orientating wheel bearings. Two rear wheel bearings can be equipped with a brake.

The distance between the front wheels along the axles can vary due to the possibility of sliding the supports with wheelsets. This extension allows you to increase the stability of the elevator in the position of the extended supports, and on the other hand allows you to import the elevator through a narrow doorway, when the supports with the wheelsets are as close as possible.

Due to the implementation of the lift only from frame elements, the lift as a whole has a lower weight in comparison with the known analogues.

The suspension of the lift and devices for caring for the sick or disabled person are selected according to their condition (severity and type of disease, weight, height, gender, etc.) or can be made to order according to individual requirements.

The elevator consists of the following main parts (see Fig. 1 - Fig. 5): a hydraulic cylinder 1, which is pivotally connected to the rack 2, and the boom 3. To the rack 2 are attached two legs expandable in width 4, at the ends of which four wheels are installed ( pos. 5 and 6), the two rear ones have brakes. The bracket 10 is movably connected to the boom 3. A beam 7 is inserted into the bracket 10, the position of which can be changed as necessary by moving it in the direction of the arrows and then fastening it with the wing screws 11 (screws with rounded tabs).

Two eyebolts 13, which are a ring with a cylindrical thickening in one part of the ring, in the center of which a hole with a thread passes, are bolted to the beam 7. Four of the same eye-nuts are mounted on the frame 8. Using carabiners 12, eye-nuts 13 and slings 14, the frame 8 is connected to the beam 7. Hooks 21 are mounted on the frame 8 for engaging the belts 20 (see Fig. 2 and Fig. 6 ) The extension and rapprochement of the supports 4 is carried out by moving the lever 9 in the direction from the hydraulic cylinder (to itself) or, respectively, to the hydraulic cylinder (from itself). To fix the selected position of the supports 4, it is necessary to tighten the wing nut 17, while the swinging stop 18 is firmly pulled to the lever 9 and prevents its movement (see Fig. 1, Fig. 3, Fig. 4). For transportation of the lift, a handle 17 with rubberized ends is provided in the room. Prior to lifting, close the exhaust valve by turning the screw 22 clockwise (see Fig. 4 and Fig. 5). When swinging the handle of the pump 16 up and down (see Fig. 3), oil is pumped into the hydraulic cylinder and the necessary pressure is created, as a result of which the piston, moving out of the hydraulic cylinder, raises the boom 3 of the elevator. To lower the patient, it is necessary to remove the handle 16 from the pump socket and, using it (or manually), open the exhaust valve by turning the screw 22 counterclockwise (see Fig. 4 and Fig. 5). The patient's lowering speed depends on the angle of rotation of the screw 22. To limit the lowering speed of the boom of the elevator, a stop 19 is fixed on the screw 22, which limits the angle of rotation of the screw.

The elevator can be transported both assembled and for ease of transportation in a partially disassembled form.

For transportation in a partially disassembled form, the hydraulic cylinder 1, the supports 4, the beam 7, as well as the protective gasket (not shown in the drawings) installed between the beam 7 and the wing screws 11 inside the bracket 10 are separated from the lift 10. The protective gasket is inserted into the gap between the beam 7 and bracket 10 bent ends towards the wing screws 11.

The principle of operation of the lift is as follows.

To care for bed patients, a suspension made in the form of a rectangular frame with straps is offered. The design of the frame provides for fastening up to 15 belts to it, the number of which is selected according to the situation, avoiding pain-sensitive parts of the body and wounds. Usually used from 8 to 12 belts. Bed care (bed linen, hygiene, etc.) can be carried out by one person without much effort. Raising the bed patient, covering the bed with a waterproof film (for example, polyethylene) and substituting small bathtubs (trays) of the right size under it, you can easily wash it directly above the bed.

In a raised state, you can examine and treat the patient’s body from the back, change bedding or move the patient, for example, to a gurney. Initially, the patient should be laid on the bed, where there should already be a frame with fastened straps. Next, laces are attached to the end of belts having special holes for this, with the help of which belts are subsequently stretched under the patient. When pulling the straps from under the patient, the laces tied to the straps are pulled under it. Shoelaces should be constantly under the patient and, if necessary, replaced with clean or sterile ones.

In order for the patient in a raised state to be in a horizontal position, and not tilted in one direction or another, it is necessary to lift the lift (namely the lift, and not just beam 7) together with beam 7 in the direction of the arrows so that the end of the boom 3 (see Fig. 1) was located above the center of gravity of the patient. The center of gravity of a bedridden person is approximately slightly below the solar plexus. When moving the lift, the patient should lie on the bed, and not be in limbo. After installing the elevator in the correct position, the beam 7, moved together with the elevator, loosening the screws 11, move to its original position and again tighten the screws 11.
