AI Technical Summary
The existing stretcher bed can only simply bind the patient's upper and lower body. The binding effect is poor. When the body shakes, the patient's arms will collide with the guardrails on both sides of the stretcher bed. The higher-height patients will extend their feet out of the stretcher bed and are in a suspended state, which is uncomfortable to use.
A stretcher bed for emergency treatment was designed, using a second binding belt, movable block and strap to bind the patient's arms, and providing foot support for tall patients through structures such as extension plates and screws, and adjusting the length and height of the bed body is achieved by using an adjustment mechanism and a limiting mechanism.
It effectively avoids the patient's arms swing when the vehicle body vibrates, ensuring the patient's comfort, especially the comfort of patients with higher heights, and can adapt to different body shapes and heights without moving the patient.
