Description

Domestic nursing bed of old person

Technical Field

The utility model relates to a special nursing bed field of old person specifically is a domestic nursing bed of old person.

Background

The "Gift & Qu Gift Shang": "Bainian Jieji Yi". "Zhengxuan Zhu: "date, you want also; nourishing Yin and nourishing Yang. The mourning of the taste of the clothes is required to be done well. "means: until one hundred years old, the filial branches of children are required to be supported in diet, daily life, activities and the like. Along with the change of social environment and the aggravation of aging tendency, the disease spectrum of the old also changes, and the disability and disability probability of the old are increased due to aging, chronic diseases, accidental injuries and the like. The disabled elderly need to compensate for the lost physiological functions of the elderly through external care.

With the perfection of the medical environment and the soundness of the medical system, people enjoy more and more comfortable medical environment and medical mode, and have higher and higher requirements on medical conditions. The aging population brings high incidence of chronic diseases, the chronic diseases become a huge medical problem, and at the moment, home care is carried forward, and another possibility is added for the nursing place and environment of the chronic diseases to meet the requirements of patients and families at different levels. Therefore, how to improve the current state of care in a home unit, guide user behavior, reduce the difficulty of care, and the like through the protector is a social problem to be solved urgently. Typical physiological, psychological and behavioral characteristics of the disabled old people when using the household nursing bed are analyzed, and the dominant and recessive demands of the disabled old people on the nursing bed are grabbed. Finally, the design of the household nursing bed suitable for disabled old people is carried out according to the user requirements, the ergonomic principle, the emotional design principle and the method.

The psychological characteristics of the elderly also change due to the changing effects of physical health, social status, economic conditions and environment, and the study of such changes is known academically as "senile psychology". Sun Simiao written in Qianjin wing prescription: the aging process of the human body is described in detail, wherein the human body is more than fifty years old, the yang qi is old, the human body is damaged and aged, the heart is gradually relieved, the human body is forgotten and is lazy, the mind and the teaching are not good at mind, the audio-visual sense is unstable, the human body is mostly retreated and advanced, the days and months are unequal, the human body is scattered, the human body is bored, the human body is forgetful and angry, the emotional variation is caused, the human body is not wonderful to eat or drink, and the human body is uneasy in sleeping … ….

Due to the gradual decline of the physiological functions of the old, the self-care ability of life is reduced, particularly the disabled old loses the life ability, the corresponding health condition is gradually reduced, the illness probability is gradually increased, and the requirement on the nursing bed of the disabled old is more urgent. Relevant survey data show that the prevalence rate of disabled old people is as high as 96.3%, which is far higher than the prevalence rate of old people in China. Meanwhile, the disabled old people may have disabilities due to the decline of various body functions, the disability probability of the disabled old people is higher than that of the old people of the same age, and the disability proportion of the disabled old people in China also tends to increase. So the disabled elderly are more urgent to the need of medical care and nursing. In life, the disabled old people need to be cared by nursing staff, and the severely disabled people also need to have the nursing staff to help to maintain normal life. The above data show that the risk of nursing problems in the life of disabled elderly people is urgently to be solved. Especially for the elderly with severe disability, the elderly are bedridden for a long time, and exercise of various functions of the body is often in a passive state or the elderly refuse to move due to pain caused by passive movement, which easily causes joint stiffness, muscular atrophy, foot drop and the like. And the reduction of the regulating function of the cerebral cortex of the disabled old patients can cause the generation of various negative emotions, so that the phenomena of insomnia, dreaminess and the like are more likely to occur, and the physical and mental health of the old patients is seriously affected.
