Description

A wake-up aid for the elderly

technical field

The invention relates to the field of health care aids, in particular to an aid for getting up for the elderly.

Background technique

The physical functions of the elderly continue to deteriorate with age, lack of exercise ability, and it becomes difficult to get out of bed. Elderly people with severe physical deterioration have difficulty getting up independently without help from others. The existing apparatus for assisting getting up is mainly the power-assisted handrails installed on both sides of the bed, and the old man supports the power-assisted handrails with his hands, and realizes the function of getting up under the support of the handrails. This way of getting up still requires a lot of active power, and this way of getting up will have certain difficulties for the elderly with serious upper limb function degradation or upper limb defects, so it is no longer suitable.

A device for assisting getting up has already appeared in China (Patent Application No.: 201721355708.4), which is composed of a fixed frame, a turning frame mounted on the fixed frame, and a turning mechanism for controlling the turning of the turning frame. The wake-up device occupies a large space and needs to be laid on the bed as a whole, and has certain limitations in width.

A device for helping patients get up (patent application number: 201610191247.5), which consists of a vertical frame, a rotating device on the vertical frame, a rocker connected to the rotating device, a bed sheet on one side of the vertical frame, and a hook on the top of the rocker The hook is hooked on the four sides of the bed sheet, and the rocker is rotated by the rotating device to control the movement of the bed sheet. The present invention is mainly used for nursing care of the elderly and patients and needs human assistance, occupies a large space and is inconvenient to use.

As my country's aging continues to intensify, there will be a major gap in products for the elderly. Among the existing aids for the elderly, most of them are assisted walking, toilets and other appliances. There are very few products for helping the elderly to get up, and the existing getting up aids have the disadvantages of taking up a lot of space and being inconvenient to use. There has not been a relatively simple wake-up assistant in China. Therefore, a more convenient and space-saving wake-up aid has been developed. It is mainly used for installation in elderly families, pension institutions, and medical institutions. Assist the elderly to get up.
