Description

An easily adjustable hospital bed

technical field

The utility model relates to the technical field of medical equipment, in particular to a sick bed which is easy to adjust.

Background technique

Traditional hospital beds are divided into non-adjustable and elevation-adjustable types. Most of the medical staff are women. When assisting in nursing patients, due to physical reasons, they cannot smoothly adjust the patient's posture more effectively. The adjustment of traditional hospital beds has relatively large limitations. Reasonable adjustments for the waist and legs are not taken into account. Because most of the medical staff are women, when they are pregnant, it is not convenient to bend over and squat down to adjust the sick bed. And the handle that is used to adjust the sickbed needs to stretch out from the sickbed in order to facilitate adjustment, which will hinder the work of the medical staff, and when passing the sickbed, it is easy to trip pedestrians and cause accidents. Although the hospital bed of electric adjustment mode is needed at present, because the price is expensive, it is difficult to popularize.

Utility model content

In order to solve the above problems, the utility model provides an easy-to-adjust sick bed, which can facilitate the adjustment of the inclination of the sick bed by the medical staff and prevent the adjustment handle from affecting the work of the medical staff.
