Emergency stretcher

摘要

A stretcher includes a patient support, a base, a plurality of support members supporting the patient support relative to the base, which are adapted and arranged to raise or lower the base relative to the patient support, and a locking mechanism. The locking mechanism is actuatable between a locked position wherein the locking mechanism locks the support members at a fixed height and an unlocked position wherein the support members are released from being locked at the fixed height so that the base or the patient support may be moved relative to the other. Further, the locking mechanism is configured to provide a stop for the support members and absorb energy from the support members are release and the support members engage the stop.
