Description

Technical Field

[0001] The invention relates to a stretcher bed, in particular to a medical stretcher bed which is convenient for lifting and placing patients. Background Art

[0002] When hospitals send ambulances to the scene to rescue people, in order to move faster and gain more time, they usually use emergency stretchers to carry patients. Emergency stretchers are easy to carry, but can only be carried by medical staff. If the rescue site is far away from the ambulance, the speed will be reduced. After arriving at the hospital, medical staff have to transfer the patient from the emergency stretcher to the rescue stretcher or medical bed. This process delays time and affects the patient's stability. At present, most hospital beds are fixed. If seriously ill patients need to change beds, medical staff need to lift the patient onto a cart for transfer, and then lift him down to another ward. Therefore, multiple conversions are likely to cause secondary injuries to the patient. There are often problems such as insufficient stretchers and inconvenient bed movement.
