目前,市售的担架展开后都比较长,在狭窄的地方如过道、楼梯、电梯等搬运伤病员时使用极为不便。为此,海军医学研究所设计研制了HY89-1型特种担架。它除具备普通担架功能外,还具备可坐、可卧、可推、可抬、可折叠的优点,是一种躺卧舒适使用方便的担架。 At present, the stretchers on the market are relatively long after they are deployed. It is very inconvenient to use the stretchers, stairs, elevators and other transport facilities in narrow places. To this end, the Navy Medical Institute designed and developed HY89-1 special stretcher. In addition to its ordinary stretcher function, it also has the advantages of being able to sit, lie, push, lift and fold, and it is a comfortable and easy to use stretcher.
