Bedside Guardrail with a Folding Table Board

TECHNICAL FIELD

The present invention relates to the technical field of bedside guardrails, in particular to a bedside guardrail with a folding table board.

BACKGROUND

In nursing scenes such as hospitals, guardrails are often set at the bedside to confine people who need nursing to the bed, so as to avoid secondary injuries caused by falling out of bed. However, most of the traditional bedside guardrails are integrated with the bed, and when guardrails are not needed, guardrails will become a great obstacle. For example, when changing sheets or mattresses, guardrails will increase the difficulty of replacement.

In the prior art, a reversible guardrail is also proposed, which can accommodate the guardrail without the block function provided by the guardrail, for example, U.S. Pat. Nos. 9,756,954, 8,104,118 and 7,784,125.

However, the guardrail disclosed above only has the function of protecting the block. In practical process, for example, when patients need to have meals in bed, they need to have meals with the help of the dining table. In order to further facilitate the nursing work, many solutions have been proposed in the prior art, such as U.S. Pat. Nos. 9,492,340 and 1,347,271A. However, the technical solutions disclosed above are cumbersome in practical use, complicated in structure and high in quality.

Although many bedside guardrails convenient for nursing work have been put forward in the prior art, users always hope to provide updated bedside guardrails, which can facilitate nursing work without affecting nursing work.

Based on the above problems, it is necessary to put forward a brand-new bedside guardrail, which has a good protection and blocking function, can confine patients to the bed, and can be conveniently and quickly accommodated by nursing workers when the blocking function of the guardrail is not needed. In addition, the guardrail also has a dining table function, which can quickly provide a support platform when patients need to have meals in bed. At the same time, the support platform has a simple structure and a low failure rate, which is further convenient for nursing work and patients to use.
