Abstract

FIELD: medicine.

SUBSTANCE: invention relates to devices for displacement of gravely sick patients and can be used in hospitals, retirement homes and apartments. Lift comprises grips, stands, sliding crosspiece, hydraulic jack, rotary-support stand, carriage, limiters of carriage turn beyond stability limits and two travel rollers, which are arranged in front part of lift and are equipped with brake. Grips are arranged as automatic. All hingedly joined elements are closed with elastic jacket. Sliding crosspiece is arranged with the possibility of changeover into transport or stationary position with the help of fixed handles and has limiters of stand rotation. All operations of displacement may be carried out by a disabled person without assistance, provided he or she may move one hand or leg, by means of hand or leg control.

Description

The invention relates to devices for the independent movement of a disabled person and can be used both in hospitals and at home.

Known devices for facilitating the care of persons with disabilities, which can be used in hospitals, homes for the disabled or at home. Closest to the proposed invention are the M-900000 and M-9000010 elevators, the mobile PDTB lift with the Megamat electric drive, the IPP-2E lift (manufacturer LLC INVA Firm www.invaprom.ru - heading: medical equipment). All of these lifts have a chair-bag, which is placed on the bed under the patient, after which the belts with carabiners are fastened to the mounting rings directly of the lift itself. The disadvantage of this device is the difficulty of self-laying on a bed and moving a disabled person to a chair-bag without assistance, as well as self-moving from a bed to a dry closet, since the device does not have a swivel mechanism. In addition, the lift is rigidly fixed to the base, so the disabled person can only independently lift his own body.

The aim of the invention is to simplify the operation of the lift and the ability to independently move along the radius when using the dry closet or when moving to a wheelchair.

This goal is achieved by the fact that this device is equipped with automatic grips, a support-rotary stand (for moving along the radius), and a sliding cross, which can be brought into a transport or stationary position with the help of lockable handles. All articulated elements of the lifting and moving mechanism are closed by an elastic casing, it is not shown conditionally in the drawing. To fix the elevator in a stationary position, two running rollers in the front of the elevator are equipped with a brake. In the transport position, there are also stops that prevent the carriage with grips from turning beyond stability to prevent the device from tipping over.

Figure 1 shows a lift for gripping, lifting and moving a disabled person. The design of this device consists of a carriage pos. 1, a force cone pos. 2, a stand pos. 3, a gripper pos. 5, a crosspiece pos. 6. The operation of the device is as follows. The lift is deployed to the stationary position of FIGS. 3, 9, 11 and is installed near the bed (sofa), being fixed in this position with rollers with a brake, see FIG. 9, pos. 4. As necessary, moving the disabled person sets the grips in the initial position of FIGS. 1, 3, after which, acting on the lever of the hydraulic jack of FIG. 1, position 7, captures and lifts the body. Then, relying on the handrail, figure 1, pos. 10, moves itself along the radius to the location of the dry closet or wheelchair. Returning to the starting position is performed in the reverse order. Thus for lowering the body to the bed (bed) to rotate counterclockwise the lock screw jack quick fit _^1/4 turn to smoothly lowering and opening of the grippers.

In the case of vertical release (landing in a wheelchair), it is necessary to lower to the seat level of the stroller of Fig. 2 and, lifting the lock, Fig. 8 pos. 4, disengage the rod from the ratchet pos. 5 of the suspension pos. 6. Then lift and release the grip of the lift.

The automatic mode of capture and rise, as well as release, occurs as follows. In Fig. 4, with a vertical action of the hydraulic jack rod, the force cone pos.2 starts to move upward, turning relative to the axis of pos.3, while the carriage does not move upward, since the hook of the cone pos.5 rolls over the bearing pos.4 of the rack and does not allow moving the carriage until the grippers completely close. After disengaging the hook of the force cone and the rack bearing, the cone head abuts against the support grips of pos.6, and all vertical forces are transmitted to the gripper, which moves upward in the horizontal position under the influence of the carriage pantograph. Closing and opening of the grip occurs from the action of the force cone on the grip bearings pos. 7 located on the extension consoles of Fig. 8 pos. 3 along the inner and outer parts (made separately for technological reasons) of the cone. That is, due to the cone, the vertical force from the hydraulic cylinder is decomposed into a horizontal one, which acts on the grips, and the gripping bearings pos. 7 are necessary to reduce friction losses and smoothness of travel.

The carriage of figure 5 of the welded structure is made in the form of a pantograph from pipes of rectangular cross-section, item 1. When viewed from above, it has the appearance of a trapezoid to impart rigidity from lateral loads.

The force cone of FIG. 6 of the welded structure is made of individual elements for technological reasons for ease of manufacture. The upper part is made in the form of a cut bell pos. 1, and the bottom in the form of a cone pos. 2.

The slewing support (for moving along the radius) of Fig. 7 consists of the axis of pos. 2, two angular contact bearings pos. 1, the housing of pos. 5, where the attachments are mounted, as well as a mechanism for adjusting the specified height of the grippers relative to sofa of the disabled person. The adjustment occurs by unscrewing or tightening the nut pos.3, while the rotation of the housing blocks the lock pos.4. In addition, the height of the patient can be adjusted with a jack screw. In the lower part of the axis, a plate of the limiter of rotation of the rack pos. 6 is welded.

The grippers of Fig. 8 are of a welded construction, made of pipes of circular cross-section, pos. 1, have support arms pos. 2 for vertical loads and sliding arms for opening and closing the grippers. In the lower part, a suspension pos.6 is installed with pickup elements from rectangular pipes. The suspension is fixed in horizontal position by a retainer pos.4, which is welded to the armrest post pos.1 and engages with ratchet pos.5.

The sliding crosspiece of Fig. 9 consists of a housing pos. 1, one fixed beam pos. 6 and four sliding beams pos. 2, 3. On the fixed beam at the ends there are two rollers with brake pos. 4, and on sliding beams are rollers without brake pos. .5. The inner and outer sliding beams are pivotally interconnected using the rods of FIG. 10, pos. 1, 2, levers of pos. 3 and the bar of pos. 4, which provide simultaneous sliding and fixing of the beams when installing the lift in the transport of FIG. 10 or stationary FIG. 11 position. The stops of Fig.11 pos.6 provide a strict position of the internal sliding beams. On the external sliding beams, pivot limiters pos.5 for the support-rotary rack are installed, which provide a reliable stop for the rotation of the rack within the stability of the lift in both transport and stationary position. When designing a mobile lift, the technical requirements and test methods according to GOST R ISO 10535-99 “Household rehabilitation lifts” were taken into account.
