RU2309715C1 - Apparatus for transfer of patients (wounded) from litter into medical modules of medical car - Google Patents

Abstract

FIELD: transport engineering, in particular, special medical cars.

SUBSTANCE: apparatus has stand for litter, guiding beams, hole in rear wall of medical module, and support which may be dropped from outside in zone adjoining hole. Stand may be of extension-type and comprises litter rest and carriage with wheels on end cross-piece. Litter rest and carriage are pivotally connected with one another. Hole and rear ends of guiding beams are equipped with roller supports positioned so as cooperate with litter rest upon rolling-out or rolling-in of stand which may be bent in extended position. Bending of stand is enabled by rotation of pivotal joint on roller supports positioned in hole and by lowering of litter rest onto support dropped from outside and rolling of carriage wheels over guiding beams up to stops provided at rear ends of guiding beams. Apparatus of such construction allows disadvantages of prior art equipment to be eliminated, in particular, complicated movement of litter over guiding beams and increased sizes.

EFFECT: simplified construction, easy rolling of litter over guiding beams, and minimized sizes of apparatus.

Description

The invention relates to transport engineering, in particular to specialized medical vehicles.

A device for loading patients (wounded) on a stretcher, containing a rack for a stretcher, guide beams, a hatch in the rear wall of the medical module, a swing-out support in the area of the hatch and a device for lifting a stretcher in the medical module of the vehicle [1].

A disadvantage of the known device for loading the wounded on a stretcher is the difficulty of moving the stretcher along the guide beams, especially when the legs of the stretcher overcome the joints and fractures of the beams, the complexity of the design, large dimensions and weight.

The technical result of the present invention is to remedy these disadvantages.

This result is achieved by the fact that the rack is retractable and includes a stretcher stand and a carriage with wheels on the end cross member, and the stretcher stand and the carriage are pivotally interconnected, and the hatchway and the rear ends of the guide beams are equipped with roller supports that are placed to interact with the stand the stretcher when rolling out or rolling up the rack, with the possibility of bending in the extended position due to rotation in the articulation on the roller bearings located in the opening of the hatch with simultaneous letting the stretcher stand onto the support that was thrown out from the outside and rolling the carriage wheels along the guide beams all the way to the rear ends of the guide beams. The rear ends of the guide beams, equipped with a swivel joint with the base of the module, and the module walls, supports and locks, provide the ability to install the guide beams in both horizontal and inclined positions and roll the stretcher not only in one, lower, but also in the upper position. The carriage, equipped with two wheels on the end cross member, allows the front end of the rack to interact with the two guide beams when rolling (rolling out or rolling) the rack. The reclining support located on the outside, made with the possibility of mounting on the rear wall of the module in a vertical position, ensures its fastening in a transport state when the vehicle is moving.

The claimed technical solution is illustrated by drawings, in which:

figure 1 - a device for loading patients (wounded) on a stretcher (general view);

figure 2 - a device for loading patients (wounded) on a stretcher (in the lower position - side view);

figure 3 - a device for loading patients (wounded) on a stretcher (with the rack retracted inside the module - top view);

figure 4 - a device for loading patients (wounded) on a stretcher (with the shelf extended from the module - top view);

5 is a device for loading patients (wounded) on a stretcher (in the upper position - side view).

The device comprises a retractable rack 1, consisting of a stretcher stand 2 and a carriage 3 with wheels 4, guide beams 5 with roller bearings 6, roller bearings 7 in the opening of the hatch 8 for loading the wounded, a tilt support 9 outside the medical module 10, a latch 11 reclining supports 9, support 12 for mounting the front handles of the stretcher in the upper position, support 13 for installing the guide beams 5 in an inclined position, locks 14 for fixing the rear handles of the stretcher in the upper position and hinge supports 15 for attaching the rear end to guide beams 5 to module 10.

The device operates as follows.

To load the wounded in a lower position, the support 9, mounted in a transport state with the latch 11 in an upright position on the rear wall of the module 10, is tilted to the lower position and the hatch is opened 8. The rack 1 is rolled out from the car, and the rear end of the stretcher stand 2 of the rack 1 is lowered on the support 9. The rear end of the stretcher stand, in this case, interacts with the roller supports 6 and 7, rolling first on the roller supports 6 of the guide beams 5, then on the roller supports 7 in the opening of the hatch 8, and the wheels 4 on the end The carriages 3 pass along the guide beams 5 on the bottom. The movement of the rack is limited by the wheels 4 resting on the rear end of the guide beams 5.

When the swivel of the support of the stretcher 2 with the carriage 3 of the rack 1 reaches the roller supports 7 in the opening of the hatch 8, the rack 1 is bent over them, which allows the support of the stretcher 2 to rotate in the swivel to lower to the support 9.

The wounded stretcher is mounted on the extended stretcher stand 2, the rear end of the stretcher stand is lifted by swiveling the stretcher stand 2 and the carriage 3, and the stretcher rack 1 is rolled inside the module 10 in the reverse order described above.

The support 9, turning, is raised to a vertical position and fixed on the rear wall of the module 10 with a latch 11, the hatch 8 is closed.

The unloading of the stretcher with the wounded is carried out similarly to the above operation of rolling out the rack.

To load the wounded in the upper position, the rack 1 is pulled out of the medical module to the outside in accordance with the procedure described above.

The guide beams 5 due to rotation relative to the hinge supports 15 are installed in an inclined position on the supports 13 for loading the stretcher in the upper position.

The wounded stretcher is mounted on the support of the stretcher 2, as in the first case, and the rack with the stretcher is rolled inside the module. In this case, the wheels 4 on the end cross member of the carriage 3 pass along the guide beams 5, and the support of the stretcher 2 is rolled sequentially along the roller supports 7 and 6. The front end of the stretcher passes slightly above the support 12 of the upper position of the stretcher.

The rear end of the stretcher is raised to the upper position until the stretcher handles are locked in the locks 14, the stretcher, in this case, rotates relative to the support 12.

Then the rack 1 freed from the stretcher is rolled out until it is mounted on the support 9.

The guide beams 5 are set to their initial, lower position and the stretcher with the second wounded is loaded into the lower position, as described above.

The support 9 is rotated in a vertical position and fixed on the rear wall of the module 10 with a latch 11, the hatch 8 is closed.

The stretcher with the wounded is unloaded in the reverse order.

The hinge supports 15 of the guide beams 5 to the module 10 can be removable, which makes it possible to lift the rack 1 together with the guide beams 5 and fix it in a vertical position on the wall of the module 10, and in the vacated space, lay out the seats for transporting the wounded in a sitting position.

Tests of prototypes confirmed the effectiveness of this technical solution.

The manufacture of medical vehicles is planned to be carried out at OAO AMZ.
