[0002] Nursing beds are the most basic and common medical equipment in hospitals. Most patients' medical treatment and care time is spent on nursing beds. However, many patients are unable to move over a large range while in bed. During the follow-up period, they need to be transferred to wheelchairs. During the transfer process, the patients are caused great harm. During the movement, the patients may accidentally collide with the guardrails, which may also aggravate the patient's injuries. At the same time, patients are in bed for a long time, and their muscles do not get the opportunity to exercise, so their muscles will atrophy, which will have an adverse effect on the patient's recovery and treatment.

[0003] At present, the blood purification multi-angle adjustment nursing beds on the market have the following disadvantages:

[0004] (1) The guardrail structure of the multi-angle adjustable nursing bed for blood purification often adopts an integrated fixing method, which makes it difficult for the patient to avoid the guardrail structure when transferring, causing the patient to collide with the guardrail, which can easily aggravate the injury;

[0005] (2) Blood purification multi-angle adjustment nursing beds are generally structured to adjust the patient's head when lying down, making it difficult for the patient's lower body to be stretched and massaged, which can easily cause muscle atrophy in the patient's lower body. Therefore, a blood purification multi-angle adjustment nursing bed is proposed. Utility Model Content
