Ultra-low bed

Abstract

The invention discloses an ultra-low bed, and belongs to the technical field of medical apparatus and instruments. According to the technical scheme, the ultra-low bed mainly comprises a bed and bedside frameworks positioned on the head and the tail of the bed, wherein the bed comprises a bed body and a bed frame for supporting the bed body; the bedside frameworks are connected with the bed frame; the bed body comprises a back frame, a waist frame, a seat frame, a thigh frame and a shank frame which are successively hinged to one another from front to back; the seat frame is fixed on the bed frame; the bed frame is provided with a first driver and a second driver which are provided with driving ends; the bed frame is hinged to a first connecting rod; a second connecting rod is arranged between the first connecting rod and the back frame; the driving end of the first driver carries out stretching motion to drive the first connecting rod to swing; one end of the second connecting rod is in linkage with the first connecting rod; the other end of the second connecting rod applies a force which enables the back frame to overturn vertically relative to the waist frame to the back frame; a hinge pin which is located in a swinging region of the first connecting rod is arranged on the waist frame; and the first connecting rod can applies a force which enables the waist frame to overturn vertically relative to the seat frame to the waist frame through the hinge pin. The ultra-low bed has the advantages of high stability and safety and long service life.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to an ultra-low bed. Background technique [0002] Calculated based on normal work and rest, people need about one-third of sleep time every day, and the comfort of the bed determines the quality of sleep to a large extent. Especially for bedridden old people, disabled people or patients, if they lie flat or on their sides for a long time, local pressure will be caused, resulting in many health problems. [0003] At present, in the field of medical equipment, many nursing beds or nursing beds have appeared. Considering the special needs of patients, the backboard, seat board, thigh board and calf board of the bed are sequentially hinged from front to back, and the back board, thigh board and The calf board can be turned over by the motor or the combination of the motor and the connecting rod, so as to adjust the sleeping position. In addition, in order to facilitate the user t...

[0003] At present, in the field of medical equipment, many nursing beds or nursing beds have appeared. Considering the special needs of patients, the backboard, seat board, thigh board and calf board of the bed are sequentially hinged from front to back, and the back board, thigh board and The calf board can be turned over by the motor or the combination of the motor and the connecting rod, so as to adjust the sleeping position. In addition, in order to facilitate the user to get on and off the bed, the head and tail of the bed are connected to the headboard, and the headboard is designed to be liftable However, the current nursing beds or nursing beds on the market have complex mechanisms for driving the backboard, waist board, thigh board and calf board to turn over, and the stability of the bedside frame is not good when it is lifted or lowered, especially when the turning and lifting actions are carried out at the same time. The whole bed is easy to shake, not safe enough, and the failure rate is relatively high
