Description

The utility model relates to medical equipment and is intended primarily for transporting people with reduced mobility inside the salons of aircraft and other vehicles and rooms with narrow, difficult to overcome walkways and stairways, as well as outside them in the conditions of airports, train stations, etc.

Technical solutions to this special problem are known, for example, the chair of the medical company Columbia medical (USA), model # 9000 SkyMaster (see the information on the website http://www.columbiamedical.com/special-needs-disabilities-products- details.asp? ProductID = 210), which has a frame with a back and seat (see Appendix 1), a footrest and a folding rear wheel support. A simple, lightweight and folding design is convenient for transporting regional routes on airplanes, but for the movement of passengers with limited mobility is not only an inconvenience, but also risks for them and operators.

Frame arc handles in the back and foot sections of the chair are inconvenient for carrying it along the ladder, since they do not meet the ergonomic requirements for their optimal width in order to combine the center of gravity of the load on the operator with the longitudinal axis of his spine, which is also traumatic for both with increased weight the passenger. Model # 9000 has a single “sitting” position, and therefore is not intended to evacuate people in a shock or coma in the “lying” position with the aim of resuscitation in emergency situations that occur in vehicles.

The closest technical solution, chosen as a prototype, is the model of the chair # 8000/8010 "AisleMaster" of the same company (see information on the website: http://www.columbiamedical.com/special-needs-disabilities-products-group. asp? ProductGroupID = 39), which has a rigid seat frame structure with six wheel supports (see Appendix 2), two pairs of folding upper rear handles and a pair of extendable lower front handles for carrying along the flight of stairs of the aircraft.

At the same time, the rear folding and extendable front handles during transportation in the working, close to vertical position of the back of the chair, when manually “carrying” it, expand along the width of the operator’s shoulders to ensure its stability while meeting ergonomic load standards. This is the first advantage of the prototype.

Of the three pairs of wheel supports of a chair with parallel axles, the middle one is located at the passenger’s center of gravity and serves to rotate the seat “in place” around the center of gravity in a limited vestibule space, and the longitudinal tilts of the entire chair around the middle wheel support allow you to overcome floor thresholds, for this the front pair wheel supports are located above two rear. This is the second advantage of the prototype.

However, the disadvantages of this chair are:

Firstly, the fact that its functionality is limited only by the movement of passengers with reduced mobility and does not allow it to provide emergency resuscitation to comatose passengers in the “lying” position when flying in an airplane or when moving outside of it. The need to provide emergency medical services to these passengers in flight is very likely, because these are mainly elderly people, sensitive to changes in pressure and humidity in the cabin.

Secondly, the lack of folding of the back section of the chair to the “lying” position of the patient complicates the movement of the passenger from the regular aviation seat to the transport chair (or vice versa), which is physically difficult for the operator and is dangerous for the passenger.

Thirdly, the rectilinear shape of the front and rear folding and extendable handles (the end part of the handle) is dangerous for them to slip out of the operator’s hands when overcoming the steep inclinations of airplane ladders and helicopter ladders, which is also associated with a decrease in the level of passenger transportation safety, especially for heavy ones.

The technical problem to which the utility model is directed is the disadvantages of the known devices, which are manifested when moving and placing a passenger.

This technical problem is solved by a transport chair containing a supporting frame with three pairs of wheel supports, a seat on the uprights, front, for example, telescopic handles, diverging in width when extended, pivotally swivel handles on the rear side of the back section of the supporting frame, in which, according to the proposal, the back section of the supporting frame is pivotally rotatable within 180 ° with the possibility of its fixation relative to the seat frame (for example, its three angular positions, of which two are plane-parallel to the seat), and pivotally Gate handle attached to the back section, are able to commit, so that they are a floor supports the back section in its horizontal position while it is advisable to handle length greater than or equal to the height of the seat to her, and their end of the handle performed annular shape.

The proposed solution allows the attendants (operator) to place the passenger (in a state of shock or coma) in the prone position for emergency medical services to the passenger in the vehicle (intubation, direct cardiac massage, injections, etc.), and at the same time reduce physical activity accompanying personnel (operators) when moving a sedentary passenger without risk of injury in the vehicle cabin from the standard seat to the transport chair (or vice versa).

The utility model is illustrated by the following graphic materials:

FIG. 1 - chair with the patient in the "sitting" position for transportation by rolling and manual carrying along the staircase;

FIG. 2 - side view of a chair with a swivel backrest in vertical and horizontal positions;

FIG. 3 is a top view of a chair with a "sitting" patient in the passage of the cabin;

FIG. 4 is a side view of a chair with a horizontal back in the patient's "lying" position to provide resuscitation;

The proposed device contains a supporting frame 1 (Fig. 1), based on three pairs of wheel supports 2-1, 2-2 and 2-3 with a seat 3 and a pair of horizontally telescopic arms 7-1 (in the retracted state - item 7- 2).

The swivel back section 5 is pivotally fixed on the frame 1: with two swivel armrests 6 with the possibility of their installation in horizontal and vertical positions, two pivotally swivel rear handles 7-3 with ring handles (when folded - pos. 7-4), fixed in perpendicular to the back section 5, the soft back 8 and the headrest 9 with fixed movements along the back 5. The hinge 10 of the swivel back section 5 ensures its rotation around the axis within 180 ° with the fixation of vertical, horizontal and middle position.

The proposed device operates in 3 positions of the rotary back section 5 as follows:

- in the vertical ("sitting") position of the back section (see Fig. 2), the chair is rolled with the patient through a narrow passage of the vehicle’s interior, mainly on a pair of rear wheel supports 2-1, 2-2 with rotations in place (in vestibules) only on the middle pair of wheel supports, as well as crossings on the thresholds on two front pairs of wheel supports 2-2 and 2-3. In the same position of the back section, the chair is manually carried over the front extended 7-1 and rear handles, in their horizontal rotated (7-3) working position, along the stairs.

In this case, in order to ensure the safety of transportation along the stairways, the handles of the rear rotary handles 7 on the back section 5 are made ring-shaped in order to prevent slipping on the steep slopes of the stairs, and safety belts are used of 3 types (Fig. 1):

- forehead 11 - to the headrest 9;

- two breastplates 12 - to the dorsal section 5 at 4 points with the simultaneous fixation of the trunk and arms;

- shin 13 - to the supporting frame 1 under the seat.

The rotation of the rotary back section 5 relative to the supporting frame 1 is made by a spring-loaded pin retainer with a drive 14 (14-1 and 14-2) in the hinge 10.

- with a vertical backrest 5, horizontal position of the front handles 7-1 and rear 7-3, the passenger is transported and carried;

- with the horizontal back position of the back section (Figs. 3 and 4), labor-intensive procedures are performed for transplanting a “sitting” patient from the standard seats (15-1 - 15-6) to the transport (or vice versa) two operators (face to face) between whom are passenger. At the same time, both operators — one with the popliteal and the other with axillary grips (shown by arrows in FIG. 3) move the passenger in the transverse direction relative to the longitudinal axis of the passenger compartment having stable leg supports in the inter-seat spaces. The necessary rigidity of the swivel backrest is provided by the emphasis of the rear handles on the floor of the cabin;

- also in the horizontal rear position of the dorsal section 5 (see Fig. 4), a shock patient lying on it may have emergency resuscitation (artificial respiration, intubation, cardiac massage, etc.) and even moving along and outside the salon when the patient is not able to sit. If necessary, in the vestibule transitions, the backrest 5 of the chair is translated into a vertical position.

- with the horizontal front position of the back section (not shown), the chair is stored and transported. Changing the position of the backrest 5 is provided by the handles of the lock 14 (14-1 and 14-2).

Thus, the introduction to the design of a transport swivel chair on a fixed hinge 10 of the back section 5 with support on the articulated swivel 7-3 - uprights of the back section in a horizontal or inclined “lying” position additionally provides the possibility in emergency situations to provide resuscitation to the patient, especially in shock condition, and transport manually on the steep slopes of the ramps, which is very important when the patient is overweight.
