Description

Medical Auxiliary Bed

technical field

The invention relates to a medical auxiliary hospital bed, in particular to a foldable medical auxiliary hospital bed.

Background technique

Hospital beds can also be called medical beds, nursing beds, etc., which are used by patients when they are recuperating. They are mainly used in major hospitals, township health centers, community health service centers, and families. According to the material, it can be divided into ABS hospital bed, all stainless steel hospital bed, semi-stainless steel hospital bed, all steel spray plastic hospital bed, etc. According to the use, it can be divided into medical beds and household beds. According to the function, it can be divided into electric hospital beds and manual hospital beds. Among them, electric hospital beds can be divided into multi-functional electric hospital beds and three-function electric hospital beds. The hospital bed has a variety of functions, such as: back up function; the back of the care recipient will slowly lift up with the back of the bed, and adjust to the best posture between 0 and 72 degrees. Folding and anti-slip function; with the function of the back function, when the back bed board goes from 0° to 30°, the support board from the hip to the knee joint of the care recipient is raised upwards by about 12°, and the back bed board continues to lift It remains unchanged at all times to prevent the human body from sliding down the end of the bed.

Nowadays, in some large hospital wards, due to the large size of the beds and the inability to adjust them, when there are many patients, only extra beds can be added in the corridor, resulting in poor rest for the patients, and because the beds cannot be adjusted, staying in the same posture for a long time will cause local muscle discomfort. For some critically ill patients, their family members or nursing staff often massage their muscles to promote blood circulation, but manual massage is laborious.
