Description

The utility model relates to the field of medicine, in particular to the rescue service, and can be used in disaster medicine, military medicine, ambulance and emergency medical services for transferring and transporting sick or injured people on stretchers.

Known patent RU22874U, published: 05/10/2002, which describes a soft frameless stretcher, consisting of a bed in the form of a flexible panel, characterized in that they are equipped with handles for carrying the stretcher, located one in the center of the end parts of the panel and four - on the longitudinal its sides.

Known patent RU192697U, published on September 26, 2019, which describes a medical stretcher, consists of a supporting part and handles; handles are tapes passing under the supporting part through its narrow side and assembled into loops extending beyond the edges of the supporting part on both sides, characterized in that the supporting part is made of woven mesh; the handles have jumpers, consisting of a fabric tape sewn in the middle of the loop, the latter are parallel to the long side of the stretcher, in addition, the stretcher has zippers, hand straps and a bottle holder.

The technical problem of the known solutions is the limitation of carrying the stretcher either with the hands or with the elbows, which is not only inconvenient, but also occupies the hands of the rescuers. Emergency evacuations, such as from fires or war zones, place great demands on bedding design. Such a stretcher must not only be used efficiently and effectively to evacuate the casualty, but must also allow the rescuer or rescuers to protect themselves and others while doing so. For example, in fire situations, it is highly desirable that the firefighter's hands remain free to continue fighting the fire or perform other tasks such as opening doors, grasping handrails, or clearing obstacles. In combat situations, it is equally or even more important for the rescuer or rescuers to have free hands to be able to keep the weapon ready. Modern stretcher designs do not provide such advantages.

In addition, known designs require at least two rescuers. But sometimes situations limit the number of rescuers to only 1 person. In the described analogues, the possibility of evacuation by only 1 rescuer is not provided.

The described technical problems are fixed in the analogue described below - US2009038076 (published: 02/12/2009), which is taken as a prototype.

The prototype describes a stretcher, which is a rectangular main section with side, head and foot edges. The side parts are located at a distance from each other and extend along the longitudinal axis, with the head and foot edges extending across the longitudinal axis between the side parts. Loop-shaped handles are attached to the edge sections of the head and foot, and two sets of loop-shaped shoulder straps are attached to the sides of the main section. The loops of the shoulder straps extend from the main part of the bedding to a much greater distance than the loops of the handles.

Thus, the side loops of one set of shoulder straps can be passed through the handle at the end of the mat and draped over the carrier's shoulders like a backpack. The rescuer can then drag the loaded trash around, leaving their hands free for other tasks. In another configuration, the shoulder straps of another set may be passed through another handle and secured to the shoulders of a second carrier. The bedding can then be lifted between the two wearers while still leaving their hand free for other tasks. In an optional configuration, the bedding can be carried by four rescuers, putting a shoulder strap on each carrier, again leaving your hands free.

The technical problem of the prototype is that a looped belt is thrown over the shoulders of the rescuer, which is fixed at its ends to different parts of the stretcher.

At the moment of moving the victim, each rescuer, who put a belt on his shoulder, has a different height and moves with his own step. As a result, the ends of the shoulder straps, fixed in different places on the sides of the stretcher, will either tighten or loosen randomly.

Thus, the victim will experience constant rolling and vibration. If at the same time he has injuries or burns, then during such transportation the victim may experience severe pain and even die from it, even if nothing threatened his life.

The objective of the utility model is to eliminate these technical problems of the prototype while maintaining all the advantages inherent in it.

The technical result is the possibility of carrying the victim with shoulder straps and at least one rescuer, while reducing vibration and pitching during the carrying of the victim by several rescuers, which allows you to carry the victim over long distances with less pain shock for him.

This technical result is achieved due to the fact that a rescue soft stretcher is claimed, which is a rectangular canvas, transportation hand loops are sewn on the long sides of the canvas, three on both sides, shoulder straps are attached to the canvas, characterized in that the rectangular canvas is stitched along the edges with a sling of nylon, loops are sewn at the edges and in the center, also in these places smaller loops are additionally sewn in which carabiners are fixed, moreover, additional smaller loops are sewn at the corners of the narrow sides of the canvas, and the shoulder straps are length-adjustable straps made of nylon slings with loops on both sides, and the straps are attached to the canvas through carabiners.

To fix the victim, fixing straps made of slings with fasteners and a length adjustment function are sewn into the canvas.

It is possible that the stretcher on the short sides of the web contains additional webs.

It is permissible that from one point near the smaller loops, indented from the edges of the web, two parallel slings 30 mm wide are sewn transversely, which have segments extending beyond the web, and fixing fasteners are fixed at the ends of the segments.

Also, starting from the edge of the canvas, the same lines can be stitched across every 7 cm, but not to the end, but end 70 cm from the edge.

Preferably, the straps are adjustable in length from 90-220 cm.

Hand loops are formed by ribbons passed through the bottom of the fabric at an angle of 45 degrees.

Implementation of the utility model

Rescue soft stretcher (see Figure 1) is a rectangular canvas 1, on the long sides of the canvas sewn in the transport manual loops 2 three on both sides, shoulder straps are attached to the canvas.

What is new is that the rectangular canvas 1 is sewn along the edges with a nylon sling 12, loops 2 are sewn along the edges and in the center, also in these places smaller loops 5 are additionally sewn in, in which carabiners 4 are fixed.

Additional smaller loops 5 are sewn into the corners of the short sides of the canvas 1, and the shoulder straps are straps 3, adjustable in length, for example, from 90-220 cm, made of nylon slings with loops on both sides. The straps 3 themselves are attached to the web 1 through carabiners 4 and can be, for example, 50 mm wide.

For better fixation of the victim, fixing belts from a sling 6 can be sewn into the canvas 1, which protrudes beyond the edges of the canvas 1 with its segments 7, at the ends of which fasteners 9 and 10 are fixed, and which have the function of length adjustment. As fixing belts 6 from a sling, for example, 35 mm wide belts with Fastex fasteners and a length adjustment function can be used.

The rectangular sheet 1 can be, for example, 170 x 70 cm or 180 x 80 cm in Oxford material D400, preferably orange. The stitching along the edges with a 12 nylon sling can be done with a tape 30 mm wide, preferably black. This stitching with 12 nylon sling provides effective retention of both hand loops 2 and additional smaller loops 5 in which carabiners 4 are inserted.

Unlike the prototype, where there is no such stitching along the edges of the nylon sling, the need to make the sling 12 is due to the fact that additional smaller loops 5 carry the full load of holding the straps 3, while in the prototype the looped belts are fixed at two ends in different places of the fabric, which reduces load on the canvas by 2 times. Therefore, without stitching along the edges with a nylon sling 12, the fabric 1 may not hold additional smaller loops 5 and they will come off.

It is also important that additional small loops 5 are sewn at the corners of the short sides of the web 1, since transport manual loops 2 are sewn along the long sides of the web - three each on both sides, along the edges and in the center. If in the center the presence of additional loops of a smaller size 5 for carabiners 4 can be implemented in the middle between the edges of the manual loops 2, then at the corners themselves additional loops of a smaller size 5 can only be located on the side of the short sides of the fabric 1, since one of the ends of the manual loop 2 fixed to the edge of the long side. And when holding the web from the side of the edge, an important circumstance for the effect of uniform tension of the short and long sides of the web is the grip of the web just by the edge, and not by the places near the edge.

In addition, additional loops of a smaller size 5 can only be located on the side of the short sides of the web, also for the reason that this is how the rescuer can transport the victim by dragging 1.

In this utility model, the technical problem of the prototype associated with fastening the loop belt to different parts of the stretcher has been eliminated. Its elimination is due to the fact that the fastening of the strap 3 is used in one place of the web. Stable retention of the loop with a carabiner is achieved by stitching with a 12 nylon sling.

As a result, at the moment of moving the victim, each rescuer who put strap 3 on his shoulder, despite the fact that he has a different height and moves with his own step, the ends of the shoulder straps, fixed in one place near the loop through which the carabiner 4 is passed, will not neither tighten nor loosen chaotically. All movement of the strap 3 will go by sliding it over the rescuer's shoulder.

Thus, the victim will not experience constant rocking and vibration, which allows him to be transported over long distances without any significant discomfort for the victim and with less pain for him.

The use of shoulder straps significantly distributes the load for the rescuer, which reduces fatigue and fatigue during long-term transportation of the victim, especially on rough terrain.

In addition, the rescuer's hands are essentially free in this state, which allows him to be able to keep the firefighter's means of fighting fire, and in combat conditions, the orderly or soldier's weapons at the ready.

The utility model is used as follows.

The web unfolds (see the example of Fig. 2). The victim is placed on it, fixed with seat belts using segments of slings 7 and fasteners 9 and 10. Transportation is carried out either by one rescuer (see the example in Fig. 4), or by a group of persons from two to six.

First, the rescuers grab the canvas by the hand-carry loops (see examples in Figs. 9-11).

If six people are transporting the victim, then they take the loops with their hands, three on one side and three on the other (see the example in Fig. 11). Each rescuer adjusts the length of the straps on his shoulder, puts it on his shoulder and then can release the hand loop (see example in Fig.8).

If four people are transporting the victim, then they take the extreme loops in the corners with one hand, and hold the central one with the other (see the example in Fig. 10). Each rescuer adjusts the length of the straps on his shoulder, puts it on his shoulder and then can release the hand loop (see example in Fig.7).

If two people are transporting the victim, then they take the extreme hand loops with their hands, or use the extreme pairs of straps, or drag the extreme straps and hand loops (see examples in Fig.5-6).

If one person transports the victim (see the example in Fig.4), then he pulls the stretcher by dragging the extreme straps. Since only one rescuer works, if necessary, he can unfasten the remaining straps with carabiners from other loops and use them to increase the length of his pulling straps, which facilitates transportation.

Straps are used to reduce hand fatigue and transport stretchers over long distances. In the case of a change of shoulder, the carabiner snaps off, the person stands in the opposite place, outweighs the strap on the other shoulder and snaps the carabiner into a special loop. Loose straps can be hooked together for lengthening, in case it is necessary to drag along any surface.

The stretcher on the short sides of the canvas may contain additional canvases 11, for example, 90 cm deep, which can be used to shelter the victim from snow or rain, or for long-term transportation of the victim, whose height exceeds 180 cm.

For a victim less than 180 cm tall, additional sheets 11 may or may not be used as part of a leg cover. For quick and short transfer of the victim, additional canvases can not be used, just put under the victim.

For a victim with a height of more than 180 cm, these additional sheets from the side of the head are simply placed under it, and from the side of the legs, they are covered from above in such a way that parallel lines are located on top. To prevent the victim from slipping during movement, he is fixed with segments of slings 7 and fastened with fasteners 9 and 10. From the side of the head, additional slings, straps, fixing devices for fixing the head and / or neck brace (not shown in the drawing) can be passed through the segments of slings 7 .

Slings 6, which fix the victim, also serve to reinforce the web 1 and redistribute the load from one point near the smaller loops. To do this, the slings 6, preferably 30 mm wide, are placed indented from the edges of the canvas 1 in parallel.

Starting from the edge of the canvas, the same lines can be stitched across every 7 cm, but not to the end, but end 70 cm from the edge.

Also, to strengthen the fastening of hand loops 2 to the web 1 and to strengthen the strength of the web 1 itself, hand loops 2 can be formed by tapes 8, passed and stitched through the bottom of the web at an angle of 45 degrees.

According to the utility model, a prototype was made, which was successfully tested for carrying victims over long distances (see examples of using the prototype in Figs. 4-11).
