Novel aging-suitable auxiliary toilet wheelchair

Technical Field

The utility model relates to a wheelchair technical field especially relates to a new-type suitable ageing supplementary wheelchair like lavatory.

Background

China enters the social stage of aging, and the aging rate of China reaches more than 20% in 2035 years, so that the super-aging society comes, the old is influenced by factors such as the decline of functions of limbs and organs, diseases and the like, the limitation of body movement is increased, the self-care ability is reduced and even lost, and the number of people gradually losing the self-care ability in the group is increased. Accordingly, the total amount and the special requirements of the elderly and the nursing staff for nursing resources are increasing. The demand of intelligent products for supporting the old to improve the convenience of the old in action is increasing day by day. However, at present, the number of domestic products for the elderly is small, the adaptability is poor, and the requirements of the existing elderly cannot be met. The auxiliary toilet is particularly remarkable in the aspect of assisting in toileting, and the old people have the problems of difficulty in squatting, inconvenience in walking, discomfort in toileting and the like in the toileting process, so that the further development of related auxiliary instruments and the improvement of the design of related products are urgently needed.

The wheelchair is an important tool for rehabilitation, is not only a walking aid for physically disabled persons and persons with mobility disabilities, but also is more important for the persons to do physical exercises and participate in social activities by means of the wheelchair. However, in public places except hospitals, people rarely see to use the wheelchair, which is mainly limited by the functions of the current wheelchair, and the traveling problem of the elderly is highlighted and continuously deepened. By analyzing the defects of the existing auxiliary tool products in the market and combining the traveling requirements of the users of the nursing wheelchair, the investigation finds that the number of the elderly semi-incapacitated old people, the incapacitated old people and the disabled people in the family-based elderly care group is large, the group uses the most auxiliary tools as wheelchairs, and even the only auxiliary tools of a plurality of families are wheelchairs. For the old and the disabled, daily activities such as going out, hospitalizing, shopping and the like are completed by the wheelchair.
