Description

RELATED APPLICATIONS

This application claims the benefit of priority to Chinese Patent Application Number 202322556766.5 filed on Sep. 19, 2023, in the China National Intellectual Property Administration. The entire contents of the above-identified application are hereby incorporated by reference.

TECHNICAL FIELD

The disclosure relates generally to devices for assisting and supporting persons, and particularly to an adjustable support apparatus.

BACKGROUND

To assist weak patients to stand up, a handrail attachment is usually installed on at least one side of the bed to provide support for the patients. Existing handrail attachments often only consider the difficulty of weak patients getting up, but do not take into account the difficulty of weak patients getting in and out of bed, as well as the difficulty of getting in and out of bed when the mattress or the bed itself is high. Therefore, there is a need for handrail attachments that can not only assisting patients to stand up, but also assisting the patient to get in and out of bed.
