Description

Portable Multifunctional Ambulance Stretcher

technical field

The utility model relates to a medical stretcher, in particular to a portable multifunctional ambulance stretcher.

Background technique

In the medical rescue in the wild environment, stretchers, operating beds, hospital beds, etc. are necessary equipment. The commonly used transportation tools are mainly hand-carried stretchers, which are mainly composed of two stretcher poles and soft canvas. The advantages are: Small size, flexible and easy to transport. But this kind of stretcher needs more artificial strength when transferring patients, and the speed is slow. Generally, there is no infusion support, which is not conducive to the rescue of patients during long-distance transfer. In addition, there is a lack of auxiliary facilities such as placing first aid equipment and medicines, which is not convenient for on-site first aid. Because of its stable mechanism, medical carts can transport patients clinically, and can be used as infusion treatment beds and ordinary hospital beds. However, due to their bulky size and inconvenient portability, they can only be used in hospitals.

Contents of the invention

The utility model aims to solve the above-mentioned shortcomings of the prior art, and provides a multi-functional ambulance stretcher vehicle which is fast and convenient to operate, requires less ambulance personnel and is easy to carry, and can quickly and efficiently rescue and transfer the wounded and sick in the field.

The utility model adopts the technical scheme to solve the technical problem: this portable multifunctional ambulance stretcher vehicle includes two wheels, and a group of scissors are supported between the two wheels, the lower end of the scissors is fixed on the wheel frame, and the upper end is fixed on the pole Above, the front end of the strut is connected with the front body, which is a scissor mechanism that can be stretched horizontally and vertically. A stretcher surface is provided; the scissor mechanism of the front body is provided with a rigid fixing piece. This structure uses the compressibility of the fork-scissor compression mechanism to complete the overall horizontal and vertical expansion and contraction of the car body. It is easy to operate, simple in structure, small in space after contraction, and easy to transport and carry; the speed of transporting the wounded is fast, saving time and effort. And the transportation is stable, reducing the secondary injury to the wounded.

For further refinement:

The rigid fixing part is composed of two small steel bars respectively connected to two adjacent scissors. The two small steel bars are connected through a rotating shaft and are provided with locking parts. After the scissors are unfolded, the rigid fixing part is stretched out, and the scissors can be locked with the locking part. When shrinking, first pull out the locking part, put away the rigid fixing part, and the scissors can shrink, thereby shrinking the entire stretcher. Increased rigidity when the hull is unfolded.

The scissor mechanism of the front car body is composed of the longitudinal scissors on both sides and the transverse scissors in the middle. Horizontal scissors realize horizontal shrinkage, and vertical scissors realize vertical expansion and contraction, which are easy to use and simple in structure.

There is a loading tray between the two wheels. The two sides of the loading tray are hinged on the wheel frame, and the middle is connected by a hinge. It can be unfolded with the unfolding of the car body, and some necessary life-saving equipment and medicines can be placed for the use of patients. . In addition, when the vehicle body is unfolded laterally, the loading tray acts as a rigid fixture in the middle to support the entire vehicle body.

The universal wheel is longitudinally equipped with shock absorbing springs. Reduce the vibration during transportation and reduce the secondary injury to the wounded.

Both wheels are equipped with brakes, which are anti-braking mechanisms. According to the working principle of the circlip pliers, the original bicycle brake device is transformed and innovatively designed as an anti-brake mechanism. When the handle is held, the brake is released to transport the patient; when the handle is released, the brake pad is used to realize the brake, and the structure is simple, safe and reliable.

One side of the wheel frame is provided with a reversible workbench, one side of the workbench is hinged on the wheel frame, and a fixed block mechanism is supported under the workbench. Some medicines, bandages, disposable syringes and other medical items needed for first aid can be placed on the workbench. In an emergency, it can be used as a simple operating bed, and there is no need to move the wounded to the operating bed when performing debridement surgery, so that timely treatment and rescue can be performed.

The other side of the wheel frame is provided with a retractable infusion support. During infusion, by adjusting the elastic nut and raising the infusion stand, the operation is convenient, and the quality of transportation and rescue of the wounded and sick is effectively improved.

There are pillows on the front part of the stretcher. Make the patient lie more comfortably.

The beneficial effects of the utility model are: 1) the stretcher can be contracted, occupies a small space, and is convenient for transportation; 2) the speed of transporting the wounded is fast, saving time and labor; 3) the anti-braking device can realize braking safely and reliably; 4 ) Spring shock-absorbing universal wheels, suitable for field rescue and transport of the wounded; 5) Multiple supporting functions, including workbench, telescopic infusion stand and loading tray; 6) Solid and durable, safe and reliable.
