Description

Technical Field

[0001] The invention relates to the technical field of transfer devices, in particular to a sedation transfer cart. Background Art

[0002] The sedation center is a specific department in a medical institution that mainly provides sedation-related medical services. Its main purpose is to allow patients to enter a relaxed and quiet state through the use of drugs or other technologies. This state helps to reduce the anxiety, discomfort and pain that patients experience during certain medical examinations or treatments. For example, when conducting some endoscopic examinations such as gastroscopy and colonoscopy, the examination process may cause physical discomfort and psychological tension to the patient. The sedation center can use appropriate sedation methods to enable the patient to better tolerate the examination. After the patient is calmed down, the family members or medical staff will transfer the patient to the corresponding department.

[0003] In the sedation center of a pediatric hospital, children are usually transported using a medical trolley or by having their parents hold them in their arms. However, medical trolleys cannot be folded for storage, and they take up a large space when in use. In addition, the trolleys are relatively long, and there are people coming and going during the transportation process. In addition, the children are usually accompanied by a family member, which makes it inconvenient to transport them between multiple departments. As for ordinary wheelchairs, although they can be folded, the backrest angle is upright and cannot be adjusted. After the child is sedated, his consciousness reaches a medium to deep sedation state, and his head cannot be fixed autonomously, and his airway cannot be opened, which may affect his breathing and is not easy to observe his complexion. Therefore, most of the older children are still carried to the examination room by their families after sedation, which not only increases the risk to the children's safety, but also brings a burden to the family members, making it difficult to meet the transportation needs.
