Description

Gravity self-driven toilet sitting/rising assisting and defecation assisting device and using method

Technical Field

The invention belongs to the technical field of toilet auxiliary tools, and particularly relates to a gravity self-driven toilet sitting/rising assisting and defecation assisting device and a using method thereof.

Background

With the increasing number of the elderly population, aging is becoming a global concern. China has a large population base, and the elderly have huge population, but the behavior research and the product design aiming at the elderly are relatively deficient in total amount and special items. Among them, the problem that the old people go to the toilet is more prominent. The old people have more obstacles and certain dangers in the toilet using process, so the design requirements of auxiliary appliances and products corresponding to the old people are urgent. The toilet bowl on the current market is rarely designed according to characteristics of audiences, has less optimization design and research on appliances used by old people in toilet, and comprises aspects of self behavior disorder and demand of the old people in the toilet process, safety consideration and comfort consideration on the toilet appliances different from healthy young people in the toilet, special psychological demand caused by physiological decline and behavior disorder and the like.

The main defects of the prior toilet bowl are as follows:

1. the height of the toilet seat is fixed, the toilet seat cushion is fixed on the toilet seat and cannot be adjusted up and down, and the old can not sit in the toilet seat flexibly due to the leg and foot, and is difficult to sit and collide easily; when rising, the user can stand up and feel labored due to lack of leg strength;

2. the toilet bowl has no leg-bending defecation assisting device (a device which is converted into a squatting posture and is easy to defecate), and the old people are often suffered from constipation, so that the defecate is easy to be unsmooth;

the accessible toilet bowl not only can bring the comfort for the old man, can also effectively avoid the old man because of the safety problem that restriction such as inconvenient activity brought, increases the security that the old man like the lavatory alone. The toilet bowl parts can be smoothly and easily operated in the toilet process of the old people to realize operations such as sitting, rising, uncovering, covering and flushing. However, the existing barrier-free toilet bowl has a simple structure, cannot realize real barrier-free or is operated and maintained unchanged by an electric control system, is high in cost and has no defecation assisting function. Although the outdoor reports that the foot stool is designed to help the old people to defecate, the problem of assisting the old people to sit/go up in a toilet cannot be solved. Therefore, a gravity self-driven toilet sitting/rising assisting and defecation assisting device and a using method are provided.
