[0002] Stretchers are important equipment for medical emergency rescue. Currently, there are lifting stretchers, wheeled stretchers, shovel stretchers, negative pressure inflatable cushion fixed stretchers, basket stretchers, and roll stretchers. Orthopedic patients often have leg, hip, and spinal injuries, which need to be properly placed and strictly fixed to prevent secondary injuries. Therefore, a portable stretcher is needed. Among them, the "composite constant temperature portable stretcher" disclosed in the application number "CN202120982818.3" is also an increasingly mature technology. It "provides a composite constant temperature portable stretcher to solve the problem of complicated injuries and long transfer time under the automatic chest compression device and Heimlich compression device. With the assistance of first aid equipment and constant temperature heating pads, the wounded can be given corresponding treatment measures in the first time, reducing the occurrence of late complications and improving the survival rate of the wounded. "However, the stretcher still has the following defects during use: the stretcher can indeed facilitate the transfer of patients through the support plate and drawer structures, but the above structure is large in size and heavy in weight, which affects the convenience of carrying. Based on this, it is necessary to provide a stretcher that is light in weight and easy to fold. In addition, the stretcher structure is inconvenient to disassemble and replace parts. Based on this, it is necessary to provide a stretcher that is easy to disassemble. Utility Model Content
