[0002] As an important medical emergency equipment, the stretcher is a medical device used to transfer and transport patients. It plays a key role in a variety of scenarios. There are many common types of stretchers, such as scoop stretchers, basket stretchers and negative pressure air cushion fixed stretchers.

[0003] However, existing stretchers have many drawbacks in actual use. On the one hand, stretchers are not portable. Most stretchers are large and have a fixed structure, making it difficult to quickly carry them to the scene and deploy them in some narrow spaces or scenarios that require rapid response. On the other hand, existing stretchers have a fixed length and cannot adapt to people of different heights. For taller injured persons, the stretcher may be too short, which may cause part of the body to be suspended in the air. This may not only make the injured person feel uncomfortable, but may also aggravate the injury because the body cannot be effectively supported.

[0004] To address these issues, we provide a portable stretcher. Utility Model Content
