The choice of material for emergency stretcher involves many aspects, including weight, strength, corrosion resistance, pressure resistance, ease of cleaning, etc. According to these characteristics, there are mainly the following types of common emergency stretcher in the market. According to these characteristics, the following are the common emergency stretcher materials in the market:
Aluminum alloy is one of the common emergency stretcher materials. Aluminum alloy has the advantages of light weight, durability, corrosion resistance, etc., which can meet the double requirements of strength and convenience of the stretcher in the process of first aid. Aluminum alloy stretcher is usually made of high-strength aluminum alloy material, which can provide enough support force in the process of carrying, but at the same time will not be too heavy, so that it is convenient for rescuers to carry quickly. Its corrosion resistance allows the stretcher to be used in a wide range of environments, including wet or seawater environments, and ensures that the stretcher will remain in good working order under adverse conditions.
Steel stretchers are generally stronger and are suitable for carrying heavier patients or for use in extreme environments. Although steel stretchers are generally heavier than aluminum stretchers, their strength and durability make them suitable for use in harsh outdoor environments. Especially in field rescue and disaster relief situations, steel stretchers can withstand greater pressure and ensure safety during the rescue process.
Polymer plastics, such as polypropylene (PP) and polyvinyl chloride (PVC), have also become one of the common materials for emergency stretcher due to their light weight, corrosion resistance and good flexibility. Plastic stretchers are usually used for short distance transportation or transfer of light casualties. Although they may not be as strong as metal stretchers, the low cost and ease of cleaning of plastic stretchers make them widely used in some settings (e.g. hospitals, clinics).
Composite stretchers have grown in popularity in EMS equipment in recent years, especially carbon fiber and fiberglass stretchers. Composite materials have high strength and low weight, as well as strong compression resistance, tensile strength and good corrosion resistance. These features make the composite material stretcher excel in high-intensity, long-time use occasions, suitable for disaster relief, outdoor emergency rescue and other complex scenes.
Stainless steel stretchers have important applications in some extreme environments due to their good corrosion resistance and high durability. Especially in the humid, salty environment, stainless steel stretcher can maintain stable performance for a long time, not easy to rust or corrosion.
emergency stretcher needs to have a certain strength and load-bearing capacity to ensure that it can safely carry patients of different sizes and weights. Aluminum and stainless steel stretchers are generally stronger, able to withstand greater pressure and less prone to deformation during handling. In contrast, polymer plastic stretchers are less strong and are suitable for light casualties or short distance transfers.
The corrosion resistance of a stretcher is critical in different environments. For example, in seaside areas or humid environments, stretchers are often exposed to moisture and salt and are prone to rust and corrosion. Aluminum, stainless steel and composite materials offer significant advantages in this regard. They effectively prevent rust and corrosion, ensuring that they retain their good appearance and functionality after prolonged use.
The weight of a stretcher has a direct impact on the portability of the stretcher when used by rescuers. Aluminum and composite (e.g., carbon fiber) stretchers have a weight advantage that enables rescuers to respond quickly in emergencies, especially in urban environments, hospitals, and other settings where frequent lifting is required. In contrast, steel and stainless steel stretchers are heavier but provide greater load carrying capacity for more demanding environments.
In complex rescue environments, stretchers may be exposed to high impact or compression forces, such as at accident scenes or disaster relief, where they may be subjected to severe vibration or compression. Composite, steel and stainless steel stretchers perform well in terms of impact and compression resistance, maintaining structural integrity under extreme conditions and protecting patients from secondary injuries.
As medical equipment, emergency stretchers need to meet high hygiene standards, and materials that can be easily cleaned and sterilized are essential. Plastic and aluminum stretchers are generally easier to clean and maintain, while stainless steel and steel stretchers may require extra attention to prevent moisture buildup and corrosion problems during cleaning.
