Description

Auxiliary bed for old people

Technical Field

The utility model relates to the field of machinary, belong to the medical instrument field, especially an old person assists bed.

Background

The aging of the population is a common development trend faced by human beings. The coming of aging brings great pressure for the general families to care for the old. Some old people have inconvenience in mobility and poor self-care ability, but many children work outside nowadays and cannot accompany the old at all times, which means that community endowment and family endowment become the key points in endowment work except hospitals. With the development of science and technology, the old can be helped in daily life by means of the science and technology. Among them, the old people have difficulty in getting on and off the bed every day due to inconvenience of legs and feet, severe hunchback, perennial fatigue, lumbar muscle strain, and the winding of joint diseases and the like.

Foreign research shows that the body functions of the middle-aged and the elderly are obviously degraded along with continuous progress of time, and specifically, the situations of reduced flexibility, poor basic self-care capability and the like of hand-foot joints and the like are presented. Old person is because the old year tired before, the condition such as accumulated strain, because shank strength is not enough and joint strain etc. when going to bed, is difficult to lift the leg to the bed, and waist strength is not enough, back stiff scheduling problem has played negative effect on old person is by sitting and standing the state to the state of lying down, at the in-process of taking care of this kind of crowd, the transform of the bed body is for the difficult problem of first priority. On the basis of not using any auxiliary machinery, the probability of causing injury to the old by the independent getting-off and getting-on errors of the old is 50%.

The aging of the population is not only a problem in China but also a problem in the world, and in the aspect of scientific research for assisting the elderly to get on and off the bed, a highly intelligent nursing bed is only developed and produced in a few enterprises and factories, such as the Stryker Medical company in the United states, the Panasonic company in Japan, and the like.

The In Touch multifunctional nursing bed is developed by Streker Medical company In America, a nursing bed is capable of helping to collect and display state information of old people and a monitoring bed by a multifunctional foot end Touch screen, and meanwhile, a plurality of voice translation systems, USB interfaces, nurse calling, four-wheel braking/driving control, oxygen bottle shelves, infusion supports and other multifunctional configurations are configured. However, due to the high price, the functions are not applicable to home use and can be basically seen only in high-grade hospitals.

The Robotibed care bed is a care bed developed by Panasonic, Japan. According to human engineering, design out the nursing bed that can interconversion between the bed body and the wheelchair, when letting the old person use, can be to the wheelchair the same to make the old person sit up and move operations such as, carried on the device simultaneously multi-functional household electrical appliances controller, make things convenient for the old person to the management of household electrical appliances, can pass through multiple control mode simultaneously, carry out the timing of the bed body and stand up, self-cleaning, discernment pronunciation etc.. The device that this design was mainly can't walk to the disabled old person, makes things convenient for the disabled old person to move at home and design is not suitable for masses old person to use. However, the intelligent nursing bed is not available in the market, and due to the high price and the requirement of accurate control and package culture of professionals, accurate judgment and operation can be carried out, so that the intelligent nursing bed is mainly suitable for patients with serious symptoms and is not suitable for furniture, and a high-intelligence hospital bed can be matched only in an ICU (intensive care unit) and the like.

The research and development design direction of the nursing bed in China focuses on the design of human engineering. The degree of research and development in China is slightly less than that in foreign countries. Along with the increase of the auxiliary functions of the nursing bed, the improvement of the intelligent degree meets the factors of convenience and safety of the old people, and the like, and becomes more and more important. With the support of the national 863 plan, there has been some achievement in the research and development design of the old mechanical direction, such as the integrated bed and chair service robot of the university of aerospace in Beijing. Nursing beds in the market can be classified into basic function nursing beds, auxiliary shift nursing beds, high-intelligence nursing beds and the like according to the division of functions. Generally, the more the number of divisions of the bed board is, the more complicated the mechanical function design is, and the more the functions are realized. However, the basic nursing bed needs nursing staff, the requirement of the old people for independent operation cannot be met, and meanwhile, due to the fact that the module is assembled, the problem of warm keeping of the old people in autumn and winter is a great test. Due to the fact that the price is too high, the common families cannot accept the nursing bed, and the high-intelligent nursing bed is difficult to find the track in the domestic purchasing channel.

At present, the common nursing beds in China are basically assembled by modules, the accompanying requirements and the working strength of accompanying personnel are reduced, the transportation, the assembly and the part replacement of the nursing beds are facilitated, and the maintenance cost caused by damage is reduced. But basically needs the accompany of nursing staff and cannot form independent operation for the old.
