Description

Technical Field

[0001] The utility model relates to the technical field of emergency stretchers, in particular to a medical anti-falling stretcher. Background Art

[0002] A stretcher is a device used to carry patients or injured persons. It is usually made of wooden sticks or bamboo poles, with canvas or ropes stretched in the middle. It is a rescue device currently equipped in ambulances. It is convenient for patients and injured persons to lie down. The purpose is to facilitate the transportation of patients and injured persons and reduce the pain caused to the injured and sick during transportation. People are usually transported in supine, lateral, semi-recumbent, prone, or sitting positions using a stretcher. Different transport positions are used according to the different injuries of the patients or injured persons, thereby reducing secondary injuries.

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN218979501U discloses a portable stretcher for dropping, which belongs to the field of medical device technology. The portable stretcher includes a supporting mechanism, a fixing mechanism, a lifting mechanism, universal wheels, and an electric inflator, wherein the fixing mechanism can support and fix the wounded placed on the stretcher from the side to prevent the wounded from sliding from the side and causing secondary injuries due to the complex and narrow rescue environment and uneven road conditions during the movement, thereby increasing the difficulty of rescue and prolonging the rescue time; the buffer device on the inner side of the railing can prevent the wounded from being directly contacted with the railing during the movement and being damaged, thereby improving comfort and playing a role in buffering and shock absorption; the first support rod and the second support rod are connected by a sliding mechanism, which can fix the lifting mechanism at a suitable height, so that the wounded can remain lying flat during the movement of the stretcher, reducing the pressure on the rescue personnel and facilitating the rapid movement of the stretcher. At the same time, the lifting mechanism can be retracted after use to save space and make storage more convenient;

[0004] Although some existing stretchers are equipped with guardrails, the height of the guardrails cannot be adjusted, which makes it difficult to meet the needs of different injured persons. In addition, the existing stretchers have a simple structure and no protective function. If they are hit during the lifting process, they will also cause secondary injuries to the patients, affecting the safety of the patients. Therefore, we propose a medical anti-fall stretcher to solve the above problems. Utility Model Content
