Background technique

As the aging society continues to intensify, the hospital medical population is growing rapidly, and the number of critically ill patients, elderly patients, and patients with mobility impairments in the lumbar and cervical spine in hospital emergency rooms is also increasing. Patients admitted to the emergency room in the emergency department generally have an acute onset and are in critical condition. After preliminary judgment and stabilization of vital signs, if the bedside examination cannot satisfy the diagnosis, in-hospital transfer is required for DR, MR, CT, DSA, PATCT, etc. Medical diagnostic tests. Although the in-hospital transfer time is short, the condition of critically ill patients changes rapidly, and most emergency patients have limited accompanying personnel. Especially for patients with suspected fractures, the top priority is to prevent secondary injuries caused during transfer and moving. To ensure the safety of transfer, it is necessary to solve the problem of how to safely and smoothly move these emergency patients from the emergency trolley to the diagnostic bed of the imaging center. This has always been a difficult problem to solve.
