Description

Portable Multifunctional Disaster Relief Stretcher

technical field

The utility model relates to the field of disaster relief stretchers, in particular to a portable multifunctional stretcher for disaster relief.

Background technique

At present, there are many kinds of disaster relief stretchers for emergency rescue on the market. Although these stretchers are portable, their weight is generally still 5-10kg, and they need special rucksacks to carry them after folding, and the stretchers have a single structure. The degree of integration is not high, the scope of use is narrow, and there are no protective measures for the wounded, so it can only play the role of transporting the wounded.

For example, the patent No. 200720023352.4 invention: a detachable folding stretcher, its main feature is that the stretcher bar is composed of three sections, connected by hinge shafts, fixed holes are evenly distributed on the stretcher bar; the two long sides of the rectangular canvas body The fixed block is evenly distributed on the fixed block, and the hook is fixed on the fixed block. The hook is matched with the fixing hole on the stretcher pole. This stretcher is detachable, foldable, takes up less space, and is easy to carry. It is suitable for small places and field rescue. Wait for use. Although the canvas is used as the load-bearing part, the stretcher pole is still solid, so that the overall quality is still heavy; in addition, the canvas will make the patient feel uncomfortable, and the extrusion of the stretcher pole will cause secondary injury; Under the condition of the water surface, it cannot play a good role, and it is inconvenient to transport the wounded across the river.

Another example is the invention with the patent No. 201020219434.8: a foldable stretcher that can be folded and has the function of infusion. At the same time, the load-bearing part is a plate body, which may have hidden dangers to the safety of patients.

Therefore develop a kind of light weight, be convenient to carry, be suitable for multiple bad environments and can not cause secondary harm to the patient and have new material, new structure, the disaster relief stretcher that standard equipment technology degree is high has broad development prospect.

Contents of the invention

The purpose of the utility model is to improve the structure and materials of the disaster relief stretcher, and provide a multifunctional disaster relief stretcher which is light in weight, high in strength and easy to carry.

The technical solution to realize the purpose of this utility model is: a portable multifunctional disaster relief stretcher is composed of a stretcher frame and a stretcher bed, wherein the stretcher bed is composed of a double-layer nylon bed cover and a built-in inflatable air cushion, and the stretcher frame is composed of a movable The stretcher is composed of joint connections, and the stretcher bed is fixed on the stretcher frame by suture or consolidation. Each stretcher joint is similar to human elbow joints. It is a left-right symmetrical structure. It is composed of PVC pipes, bolts, nuts, aluminum blocks, and detachable aluminum baffles. There are threaded holes with the diameter of the bolts on the aluminum blocks. The PVC pipes are placed Between the aluminum blocks and use bolts to connect the PVC pipe with a round hole on the top to the aluminum block, adjust the bolts so that the distance between the aluminum blocks is equal to the outer diameter of the PVC pipe and fix the aluminum block with nuts, on the upper end of the inner side of the aluminum block and with the outer ring of the PVC pipe There is a groove at the position aligned with parallel equal heights, and a detachable aluminum baffle is set on the groove, and the width of the detachable aluminum baffle is the sum of the outer diameter of the PVC pipe and the depth of the groove.

There may be 2, 4 or 6 joints of the stretcher.

The built-in inflatable air cushion can be inflated manually or automatically.

The principle of the utility model is: use light weight, high strength PVC pipe instead of traditional aluminum material, greatly reduce the quality of the stretcher, reduce the burden of carrying; use the flexible and convenient three-section joint to make the stretcher fold and unfold It is more convenient, and at the same time reduces the folded volume of the stretcher, which is easy to carry; using an inflatable stretcher bed can not only reduce the chance of the wounded being injured again, but also adapt to the rescue work under special circumstances such as floods that require wading. Both the wounded and the rescuers are protected.

Compared with the prior art, the utility model has the remarkable advantages of:

1. In terms of materials, it gets rid of the traditional stretcher bracket’s demand for aluminum and other metal materials, and uses a new type of polymer material PVC. As a new type of polymer material, PVC has the characteristics of small weight, high strength, and low price. Use As the material for the stretcher support, this material can greatly reduce the weight of the stretcher support while ensuring its load-bearing strength, making the stretcher support lighter and more convenient to carry around.

2. The structure of the stretcher uses a conventional joint folding structure, which can make the structure of the stretcher smaller, and can be placed in an ordinary shoulder or backpack without taking up much volume and without special carrying equipment. This design not only The size of the stretcher is reduced, and the portable multi-functional disaster relief stretcher can be used not only in rescue and emergency rescue, but also in emergency supplies for family travel, which broadens the scope of use. At the same time, the portable multifunctional disaster relief stretcher uses simple joints to fold and is easy to disassemble. When the stretcher is damaged, it can be disassembled to replace and repair the damaged part. The simple design also greatly improves the service life of the stretcher. It serves multiple purposes.

3. The bed of the portable multifunctional stretcher is double-layered, with a layer of inflatable air cushion built in the middle. When the air cushion is opened, it can play a cushioning effect, increase the comfort of the stretcher, reduce the pain of the wounded, and at the same time prevent the wounded from secondary injury caused by excessive bumps, and protect the personal safety of the wounded. The introduction of the inflatable air cushion also realizes the multi-function of the stretcher. Conventional stretchers are useful in earthquakes, but not in floods. The portable multi-functional disaster relief stretcher can be used as a simple floating boat after opening the air cushion. It can be used to transport some special people, such as the elderly, in places that are difficult for assault boats to reach. Rescuers avoid the dangerous situation that occurs due to lack of physical strength when rescuers hold the elderly or the wounded and swim out of the trapped area.
