Description

The present invention relates to the field of sanitary equipment intended for the evacuation of victims from a disaster area on a stretcher and then using vehicles, mainly aircraft.

A known attachment system for a sanitary stretcher [1], containing two transverse tapes with locks covering the stretcher at the shoulders and at the patient’s waist, and two longitudinal tapes secured with front ends to the transverse tape at the patient’s shoulders and crossed at the patient’s waist. The transverse tape at the patient’s shoulders is drawn through the front legs of the stretcher, and one longitudinal tape is hooked on the rear legs of the stretcher, covering the patient’s legs from above, and is connected by a lock to the second longitudinal tape.

Such a tethered system, consisting of long tapes laid separately on a stretcher, is inconvenient to operate, complicates the process of fixing the patient on a stretcher in an environment where the evacuation of victims must be carried out without delay.

The absence of a safety belt for connecting the patient with the construction of the vehicle (aircraft) requires special rigid equipment, for example, a rigid section of two racks with a crossbeam and with diagonal braces, with side consoles fixed to the racks and equipped with locks for attaching the stretcher [2]. Only specialized hospital aircraft are equipped with such equipment.

Known attachment system, permanently fixed on a sanitary stretcher [3], containing cross belts and shoulder straps connected to the front cross belt attached to the patient’s shoulders to the crossbar of an inclined frame pivotally mounted on the stretcher frame.

Such patient fixation is provided for special stretchers, the design of which provides the ability to adjust the inclination of the patient's back.

Shoulder straps mounted on the crossbar of the swinging frame with the necessary distance between them do not jump off the patient’s shoulders, and the frame with the tarpaulin stretched on it together with the straps holds the patient in case of longitudinal overload during an emergency landing.

Also known is a manually movable medical cart equipped for medical operations [4], in which the harness is made with shoulder straps also attached to the inclined frame behind the patient’s shoulders, and their ends brought together over the patient’s torso are connected by a long belt to the rear edge carcass frame.

Thus, the convenience of fastening for patients in serious condition is increased. However, this design, as described above in [3], is unacceptable for conventional sanitary stretchers, mainly folding longitudinally, without transverse rigid belt fastening elements.

The closest technical solution (prototype) is a tie system for a stretcher company SCHROTH [5], containing a shoulder and waist belt connected by a common lock, and a separate leg belt. Shoulder straps are made with inertial retraction mechanisms. This tethered system provides increased comfort for the patient and is installed with permanent fastening on special medical stretchers or trolleys used on hospital aircraft.

The objective of the invention is the creation of an easily removable tethered system suitable for use on ordinary sanitary stretchers, while ensuring the safety of the transport of stretchers with injuries on an airplane.

The task is achieved due to the fact that the tie system for the stretcher, containing the shoulder, waist and leg belts, is equipped with a longitudinal jumper of tape connecting the shoulder, waist and leg belts, a transverse jumper of tape, with loops at the ends worn by these loops on the shoulder straps, while the shoulder straps are made with loops at the ends worn on the handles of the stretcher, and the foot strap is made with a lock connecting its ends to form a loop covering the legs of the stretcher.

The tie system is equipped with a safety belt fixed and laid on a longitudinal jumper connected by a free end to the vehicle structure.

The inventive attachment system for a stretcher has a combination of differences, ensuring its ease of removal.

The loops at the ends of the shoulder straps allow them to be worn on the handles of a conventional sanitary stretcher, while the transverse jumper worn by the loops on the shoulder straps does not allow them to slide off the patient’s shoulders, while providing the opportunity to adjust the most convenient position of the jumper over the patient’s shoulders.

The longitudinal jumper connecting the shoulder, waist and leg belts fixes a certain position of the belts relative to the patient’s body when putting on the harness, while holding the safety belt in the folded position along it. This ensures the convenience of using the tethered system outside the vehicle and during loading. The connection of the ends of the leg belt with each other with the formation of a loop covering the rear legs under the stretcher, allows you to fasten the belts without additional special mounting nodes on the stretcher. The easy removability of the harness allows it to be used on ordinary sanitary stretchers, both folding longitudinally (with transverse crossbars having hinges) and not folding.

In addition, the claimed tethered system, which transfers the longitudinal load from the patient directly to the design of the stretcher in the aircraft through the safety belt, simplifies the fastening of the stretcher in the aircraft, using vertical struts and stretch marks.

Thus, the use of the specified combination of distinguishing features in the claimed device allows expanding the possibilities of using conventional sanitary stretchers (and not just special ones) during mass operations to transport victims from disaster areas using airplanes.

The essence of the invention is illustrated by drawings, in which:

The attached system for sanitary stretchers (Fig. 1) contains shoulder 1, waist 2 and foot 3 belts connected by a longitudinal bridge 4, which is a belt with metal links 5 and 6 at the ends, which are made with eyes, and link 5 and c transverse element 7, with a lining 8 of the belt, fixed by the ends on the jumper 4, spanning across the waist belt 2. The shoulder belts 1 are connected by converging ends on the longitudinal jumper 4 through the eyes of the link 5 (figure 2) and have loops 9 at opposite ends, which they are put on kark as 10 sanitary stretchers through the handles 11. The shoulder belts 1 are connected to each other by a transverse jumper 12 made of a belt, with loops 13 at the ends by which the jumper 12 is worn on the shoulder belts 1. A waist belt 2, passed between the belt of the longitudinal jumper 4 and overlay 8, covers the stretcher from the bottom, and its ends are interconnected by a lock 14. An ankle strap 3 connected to the longitudinal jumper 4 through the eyes of the link 6, a loop formed by the opposite ends, by means of the lock 15 covers the legs 16 of the stretcher (Fig.3). The safety belt 17, covering the transverse element 7 of the link 5, is mounted on the longitudinal jumper 4 (figure 4). At the opposite end, it is made with branches 18 and 19, the ends of which are connected by a lock 20, forming a loop covering the rack 21 for attaching the stretcher on the plane during transportation of the stretcher with the patient. In the idle position, the safety belt 17 (Fig.6) is laid on the longitudinal jumper 4 and fixed on it with two tapes 22 with textile fasteners 23 (Fig.7).

The operation of the tethered system for sanitary stretchers is as follows.

The harness is put on the stretcher before loading the stretcher with the patient on the plane.

The shoulder straps 1 are put on the frame 10 of the stretcher with loops 9 through the handles 11 on the side of the patient’s head, a transverse jumper 12, the loops 13 at the ends of which allow it to be moved along the shoulder straps 1, move under his neck and, putting the shoulder straps 1 over the shoulders, put the longitudinal the jumper 4 with the folded safety belt 17 on the body, after which the leg belt 3 is held under the stretcher, covering the legs 16 of the stretcher, connect its ends to each other with the lock 15 and pull the leg belt 3 for a snug fit of the harness belts to the patient’s body NTA.

The waist belt 2, the position of which is fixed by the lining 8, is carried out under the stretcher, connect its ends to each other with a lock 14 and tighten for a snug fit to the body.

After loading and securing the stretcher with the patient in an airplane, the textile fasteners 23 of the belts 22 on the longitudinal bridge 4 are disconnected, a safety belt 17 is deployed, fixed to the transverse element 7 of the link 5, and attached to the rack 21 of the stretcher, for which it is covered with branches 18 and 19 and connect their ends with a lock 20, pulling the branch 18 for tight gripping of the rack 21.

In the case of an emergency landing by the aircraft, when inertial forces act, the patient is held on a stretcher from longitudinal movement by shoulder straps 1 connected by a transverse jumper 12, while the load from them is transmitted through the safety belt 17 to the stretcher mounting rack 21.

The inventive safety system, installed on ordinary, the most common sanitary stretchers, is a single, integral device that can improve the efficiency of rescue operations with the evacuation of victims from the disaster area using aircraft.
