RU60861U1 - MEDICAL STRETCHERS - Google Patents

Abstract

Medical stretchers are medical equipment and can be used to transport victims in the field during natural disasters, in mine workings, and in medical work. Medical stretchers represent a rigid base, which is made in the form of an octagon elongated along the axis of symmetry, with head and foot parts tapering to the edges, with fixed handrails fixed around the perimeter on one side of the stretcher, and the presence of removable handrails on the opposite side that connect to each other using locks. The stretchers are also equipped with means for fixing the victim and a roller for placing him under the knee joints of the victim. The proposed design of medical stretchers helps prevent additional injuries to injured and seriously ill people when placed on a stretcher, significantly reduces the size of the stretcher to 160 cm in length and up to 50 cm in width, while reducing their weight. As a result, it makes it possible to transfer the victims in small-sized residential and industrial premises and in other hard-to-reach places, to lift a person from mines, wells, gorges, etc., and also convenient for lifting, carrying and evacuating corpses, for use in morgues.

Description

The device relates to medical equipment and can be used to transport victims in the field during natural disasters, in mine workings, in the work of medical institutions, including ambulances.

Known devices designed for use in emergency medical care to transfer a seriously ill patient from the place of its discovery.

For example, stretchers are known according to RF patent No. 2058765 dated 04/27/1996, which consist of two longitudinal telescopic beams, transverse and panels, and are equipped with a device for their deployment, made in the form of couplings with central holes for longitudinal beams, and also mounted on longitudinal beams clamps and limiters of movement of couplings, fixing belts for fastening the victim. The disadvantage of this device is the design complexity and the need to prepare them for use.

The stretcher according to the patent of the Russian Federation No. 2182477 dated 05/20/2002, which is a rigid base of a flat hydrophobic material in the form of a cone, tapering to the legs, and with a head part, the length and width of which is greater than the length and width of the victim, was selected as a prototype means fixed on the basis for fixing the victim in the form of straps from tapes fixed with locks.

However, these stretchers, like the previous ones, are intended only for the transfer of a seriously ill person. But before you transfer, you need to put it on a stretcher. Usually this is done like this: more often two, at least three or four people, first somehow raise the victim, and then lay on a stretcher. During the rise, due to the displacement of body parts, the load on the activity of the nervous, cardiovascular, respiratory and other systems increases, often additional damage to the internal organs, nerve trunks and

blood vessels from bone fragments, which can entail a sharp deterioration in the condition or some other complications of the underlying disease and lead to death.

The objective of the proposed technical solution was the development of such a design of the stretcher, which would, firstly, eliminate the possibility of additional injuries during manipulation of the body and limbs of a person when placing it on a stretcher and, secondly, allow them to be used in narrow and small-sized rooms, and also in other hard-to-reach places.

The problem is solved as follows.

The claimed stretchers are a rigid base in the form of an octagon with tapering to the edges of the head and foot parts, made of thin but durable material, with the presence of fixed handrails fixed around them on the perimeter and on the opposite side of the stretcher - removable handrails that connect between each other using locks. In addition, a roller is proposed for stretchers to place it under the knee joints of the transported.

Signs that suggest that such a technical solution is unknown from the prior art, i.e. meets the criterion of "novelty" are the following:

- the implementation of the base of the stretcher in the form of an octagon with tapering to the edges of the head and foot parts, which increases the convenience of carrying, especially in narrow and small-sized rooms, as well as in other hard-to-reach places;

- the presence of a roller for placement under the knee joints allows you to give the patient the most physiological position, and at the same time reduces the dimensions of the stretcher to 160 cm in length and up to 50 cm in width, which further increases the convenience of carrying, especially in narrow and small-sized rooms, as well as in other

inaccessible places and at the same time reduces the weight of the stretcher itself, i.e. facilitates patient transfer;

- the presence of handrails around the perimeter of the stretcher, with fixing straps fixed on the handrails, allows the patient to be fixed to prevent possible changes in the position of his body on the stretcher when carrying in narrow and inaccessible places;

- the execution of handrails on one side of the handrail with removable ones allows you to place the person on the stretcher after lifting them, without lifting it, but gradually moving it while maintaining its position unchanged, which prevents the appearance of additional damage to internal organs, nerve trunks and blood vessels from bone fragments.

The proposed stretchers characterize the images:

figure 1 - removable handrail (top view);

figure 2 - stretcher (top view with removed removable handrail);

figure 3 - stretcher side view.

The stretchers contain a rigid base 1 in the form of an octagon with tapering to the edges of the head 2 and foot 3 parts. On one side of the base 1, fixed handrails 4 are fixed around the perimeter, and on the opposite side of the base 1 there are removable handrails 5. Moreover, the handrails 4 and 5 are interconnected by two clamps 6, while the edge of the base 1 is included in the groove of the removable handrail 5 (in the diagram shown). Handrails are equipped with fixing belts (not shown in the figure).

Usage example

A removable handrail 5 is separated from the stretcher and the base 1 of the stretcher with the open edge to the maximum possible depth is placed under the patient (under a sheet or blanket, if any, or under clothes), after which the patient is moved by a draft for a sheet, blanket or clothes to a stretcher. A removable roller 7 is placed under the patient’s knees, which gives the lower limbs an average physiological position and reduces body length for ease of placement on a stretcher. Then

install a removable handrail 5, connecting it to a non-removable handrail 4 using the clips 6. And fix the patient on a stretcher with fixing straps.

The stretcher can take:

- 4 people, located in the places of narrowing in the head and foot parts, which facilitates the carrying of the stretcher in narrow and uncomfortable places for passage;

- 3 people, two of whom are in front, in places of narrowing, and the third is behind;

- 2 people.

The proposed design of the stretcher helps to prevent additional damage to injured and seriously ill people when placed on a stretcher, and due to the reduction in size and weight, it facilitates the ability to carry or evacuate transported through narrow and small-sized rooms, allows them to be lifted from the mines using ropes, and, in addition, convenient for use in morgues when lifting and carrying corpses.
