Here are some key points about stretchers:

1. Design and Structure: They typically consist of a lightweight and durable frame with a platform on which the patient lies. The platform is typically adjustable in height, and some models can adjust the incline of the head or leg sections.
2. Wheels: Stretchers have sturdy wheels, which allow for easy transportation. The wheels often come with locking mechanisms to keep the stretcher stationary when needed.
3. Rails: They often come with rails on the side to prevent patients from falling off and to give them something to hold onto. These rails are typically collapsible for easy patient transfer.
4. Accessories: Many stretchers come with hooks or spaces for attaching medical equipment, such as IV poles or oxygen tanks. There may also be storage areas underneath the stretcher platform.
5. Types: There are different types of stretchers tailored for specific uses. For instance, ambulance stretchers are designed to be easily loaded and unloaded from ambulances. Some stretchers are also designed for specific medical scenarios, like those for radiological procedures.
6. Material and Cleanliness: They are made of materials that are easy to clean and disinfect, as maintaining hygiene is crucial in a hospital setting.
7. Adjustable Features: Some advanced models can be adjusted electronically using remote controls. This is especially useful in critical care settings where the patient’s position might need frequent adjustments.
8. Load Capacity: Stretchers are designed to carry varying weights, but most standard models can carry adult patients of varying sizes. However, there are also bariatric stretchers designed specifically for larger patients.
9. Uses: Apart from transportation, stretchers are also used for temporary holding of patients in busy settings, like emergency rooms, until a bed becomes available.
10. Safety: Safety is a critical concern with stretchers. They must be used appropriately, with care taken to lock wheels, adjust safety rails, and ensure the patient is secure.

Stretchers play an essential role in patient care and logistics within medical facilities. Whether it’s quickly moving a trauma patient to an operating room or transporting a patient for a diagnostic test, the stretcher is a vital piece of equipment.
