Description

A bed-chair integrated device for assisting the elderly with inconvenient legs and feet

technical field

The utility model relates to a nursing appliance, in particular to a bed-chair integrated device for assisting the elderly with inconvenient legs and feet.

Background technique

The World Health Organization stipulates that the elderly over 60 years old reach 10% of the total population or the elderly over 65 years old reach 7%, which is called population aging. According to the survey, the total number of people over the age of 60 in the world has reached 600 million, and the elderly population in more than 60 countries has reached or exceeded 10% of the total population, and has entered the ranks of an aging society. The rapid development of population aging has aroused the attention and concern of the United Nations and governments around the world. Since the reform and opening up, China has emerged as the world's second largest economy, and an important growth driver is the demographic dividend. However, since 1990, China's fertility rate has been lower than the level required for normal population replacement. In 2000, China entered an aging society and is rapidly moving towards a deeply aging society. Because my country has the largest elderly population in the world. In addition, due to the large population in our country, the number of disabled persons due to various diseases, work-related injuries, traffic accidents, etc. is increasing year by year. In order to better serve these vulnerable groups and to achieve the grand goal of "rehabilitation services for everyone", the central and local governments are also vigorously supporting the development of the rehabilitation equipment industry. The Ministry of Science and Technology has accumulatively invested nearly 500 million yuan in national "973", "863" and "Technology Support Plan" related to rehabilitation equipment.

The self-care bed is a practical new type of care product for the convenience of taking care of the disabled. At present, the research on the mechanical function of the self-care bed has been basically completed in the relevant domestic enterprises and research institutes, which is not weaker than that in Europe and the United States. What is lacking is intelligent control technology, human-computer interaction and sensor fusion technology. The lack of these key technologies leads to the fact that highly intelligent self-care bed technology is only in the hands of developed countries. However, the high-intelligence self-care bed on the domestic market is hard to find or the price is unbearable for most families who need it. For patients and families, self-care beds are very important to enhance nursing capabilities, reduce the burden on families and society, and help patients get better soon. return to society. The intelligent self-care bed can intelligently assist patients to turn over, lift their backs, flex their legs and extend their legs to prevent bedsores. It can intelligently assist patients to defecate, facilitate cleaning, and reduce the intensity of nursing care. Under normal circumstances, daily nursing tasks such as getting up, outdoor rehabilitation, bed conversion between departments, and cleaning and convenience are completed, which greatly reduces the labor intensity of nursing staff and improves work efficiency. At the same time, reduce the psychological burden of the caregivers and increase their comfort.

From a technical point of view, the current domestic research and development focus is more on the design based on Chinese ergonomics, while the development of self-care bed products by foreign companies includes technology and intelligence. In addition, high-end intelligent self-care beds are only developed and produced in large quantities by a few developed countries, such as Stryker Medical Company in the United States, ArjoHuntleigh Company under GetingeAB Group in Sweden, and Paramount Bed Company in Japan. Most of the high-intelligence self-care beds in China are still in the laboratory stage, such as the bed-chair integrated service robot of Beihang University, and the multi-functional rehabilitation self-care bed robot of Shanghai University of Technology. The following describes several representative intelligent self-care beds and technical parameters.

The self-care bed can also customize automatic cleaning and timed turning to change the patient's position. The built-in pressure ulcer assessment scale, Braden Scale, is convenient for doctors and nurses to understand the patient's condition and customize different rehabilitation plans. Music and beautiful sounds of nature can also be played to relieve the patient's stress. Data synchronization can be achieved by using the InTouch self-care bed in the ICU ward.

All components of this self-care bed are modularly designed and can be disassembled and replaced for easy maintenance. This body care bed can accurately measure the body weight of the recorder, the error is within 500g, and the maximum load is 250kg. It can electrically adjust the height, tilt, back up, knee bend, leg lift and other functions of the bed. And these changing angle values can be displayed on the control panel in digital form. In addition, considering the possibility of emergencies, this self-care bed supports automatic CPR and manual CPR on both sides. The self-care bed is equipped with an evaporative cleaning and sterilization system, which can keep the self-care bed clean and improve the comfort of patients Degree also reduces the nursing intensity of nursing staff.

(4) Qualitas Gamma self-care bed: Japanese company PARAMOOUNTBED has developed a Qualitas Gamma self-care bed. The design is based on the principles of safety, initiative, high efficiency and high quality. Trendebren's recumbent position change, there are two control modes: patient control and nursing staff control, which is convenient to operate. And according to the theory of ergonomics, all the buttons are designed to prevent accidental pressing to ensure the safety of users. Special materials are selected for production, which can be compatible with X-rays. The foot board of this self-care bed can be adjusted automatically by sensing the position of the patient's feet. In addition, this self-care bed has interfaces for oxygen inhalation machine, CPR, and infusion stand, and a frame for muscle traction is attached to ensure as much as possible. life safety of patients and improve the effect of rehabilitation treatment.

(5) Robotic bed self-care bed: Japan Panasonic company issued a Robotic bed, which is designed according to ergonomics, so that the bed body can drive the user to sit up like a wheelchair and open the bed frame, and the prevention of bedsores has also expanded At the same time, this self-care bed also contains an advanced home appliance controller and screen as well as third-party video monitoring equipment, which greatly reduces the work intensity of nursing staff.

(6) Multifunctional rehabilitation self-care bed robot: In 2013, the Institute of Rehabilitation Engineering and Technology of the University of Shanghai for Science and Technology cooperated with enterprises to design a multifunctional rehabilitation self-care bed robot. This self-care bed has a wheelchair-type automatic bed body separation. , Docking function, the main body of the wheelchair bed has nursing functions such as standing, turning over, and urination and defecation, and can control the barrier-free environment at home.

Therefore, there is a need for improvements to the prior art.
