RU139294U1 - Stretcher for rescue work of the Ministry of Emergencies - Google Patents

Abstract

Sanitary stretchers are characterized in that they consist of pivotally connected parts forming load-bearing rails with the possibility of giving the stretcher different configurations, while the middle part of the stretcher is adapted as a seat with containers mounted under it, in addition, piano wheels are installed at the ends of both load-bearing bars the structures and on the rungs are mounted eyebrows (rings), and in the middle of the stretcher there is a device for attaching the stretcher with straps to the transporting stretcher manually.

Description

The proposed utility model relates to the field of medical equipment, namely to sanitary stretchers and can find application in medical institutions, in the field, during natural disasters for transporting patients and the wounded with various types of injuries. Known stretchers that contain a rigid base in the form of an octagon. With tapering edges around the head and legs and a footrest with removable and non-removable handrails, clips and seat. The seat is pivotally mounted on the base and provided with a fixing plate (patent No. 2400201 2009, IPC A61G 1/0013).

Stretchers are also known, which consist of two load-bearing bars in the form of telescopically connected handrails of a pipe profile. The pipes are connected by transverse locks detachable relative to the axis of the stretcher. On some pipes clamps are installed, and on others - conical branch pipes. RF patent №2013086 1991, IPC A61G 1/003, F61G 1/07. The disadvantage of the above stretchers is that they are dimensional, difficult to use in hard to reach places, especially in the absence of a transportation partner. When transporting these stretchers, at least two people are needed, and in extreme conditions a shortage of people is not excluded, which complicates the rescue operations. In addition, during rescue operations, medicines and auxiliary materials are needed in separate containers, the absence of which further complicates the implementation of rescue operations, especially in the field.

The objective of the proposed utility model is the ability to conduct rescue operations with the least number of personnel. The essence of the utility model of sanitary stretchers is characterized by the fact that it consists of articulated parts that form crossbars with the possibility of giving the stretchers different configurations, while the middle part of the stretcher is adapted as a seat with containers mounted under it. In addition, in the lower part at the ends of both load-bearing crossbars pianoforte wheels are installed and rods (rings) are mounted on the load-bearing crossbars, and in the middle part of the stretcher there is a device for fastening the stretcher with belts to the lifeguard transporting the stretcher manually.

Sanitary stretchers can be used in medical institutions and in rescue operations of the Ministry of Emergencies in the field, during natural disasters for the transportation of patients and wounded with various types of damage. The design of sanitary stretchers uses rectangular hollow profiles of light and sufficiently strong aluminum alloys (babbit) with a selection of profile section parameters of approximately - 20-70 mm with the ability to fold the stretcher in the form of a small space.

The design of sanitary stretchers uses rectangular hollow profiles of light and sufficiently strong aluminum alloys (babbit) with a selection of profile section parameters of approximately - 20 × 70 mm with the ability to fold the stretcher into a small place, change the way the victim is transported - lying and in a sitting position (even in a state of imperceptibility), the ability to raise the victim from any hard-to-reach place. At the same time, sanitary stretchers should be light (weighing no more than 3 kg), rationally compact, able to guarantee the transportation of victims weighing more than 150 kg.

Description of the design of sanitary stretchers.

In the design of the stretcher, you can use babbitt profiles: a hollow rectangular section with shelf sizes of 20 × 70 mm and a wall thickness of 3-5 mm, as well as babbitt pipes with a diameter of 30-40 mm with wall thickness according to the established standard. Both materials should provide design strength, design strength for all design parameters, taking into account the drilling of holes for fastening elements of structural parts. Stretcher width no more than 500 mm, length 1800 mm. Weight is approximately 30-35 kg.

Stretcher Design

The design of the stretcher is collapsible. folding in three parts (see figures No. 1-2). In the seat area (the middle part of the stretcher is approximately 350 mm long) there are 4 rotary axes with 2 axles on each rail (see figure No. 3). The upper part of the stretcher (back) is 900 mm long. The lower part of the stretcher (the supporting part of the stretcher for the wheels and legs of the victim) is approximately 550 mm long (see figure No. 3). In the carrier rails for fixing the width of the stretcher, 4 transverse bars are mounted (see Fig. No. 1). At the ends of the supporting slats, handles are screwed into wooden bosses 200 mm long, inserted into the hollow part of the rail profile for screwing handles into wooden bosses and carrying the stretcher. On the lower (supporting) ends of the stretcher, one wheel with an axial support of the piano system is attached to the lower shelf of the load-bearing rails, making it possible to roll the stretcher with one rescuer injured on the ground (see Fig. No. 3). The stretcher can be deployed in a horizontal position and fixed with retaining strips located on the rails (see Fig. No. 1-2) and assemble in the form of a chair and also secured with retaining strips (see Fig. No. 3). The stretchers are equipped with eyebells (rings) welded to the upper shelf of the load-bearing rails for fastening the victim's stretchers and lifting the stretchers with the injured by mechanical lifting means. In the area of the seat (the middle part of the stretcher), 2 containers are arranged under the seat - for emergency medical supplies and for fasteners - fabric and leather straps, ropes, harnesses, tires, etc.

Use of a stretcher.

The stretcher can be delivered to the victim’s place in a prefabricated or collapsible form by one rescuer manually. Next, the stretcher is laid out in a horizontal position or in the “stool” position (see Fig. No. 3), having made the appropriate fastening (fixing parts of the stretcher). In any case, the injured person is tilting to the stretcher with appropriate fastening materials. The stretcher can be carried by two lifeguards, rolled on the ground with one lifeguard in an inclined position or in the “stool” position, lifted by mechanical lifting means. Stretchers can be delivered to any inaccessible place and even by helicopter.
