Description

Multifunctional combined wheelchair bed nursing system

Technical Field

The invention belongs to the technical field of medical instruments, and particularly relates to a multifunctional combined wheelchair bed nursing system.

Background

China has entered into an aging society in 1999, and the aging population is absolutely large and grows rapidly. Therefore, it is important to solve the problem of nursing the elderly and to make the elderly better enjoy life. The multifunctional intelligent nursing bed assists the bedridden old people to complete the adjustment of body postures such as back rising and falling, leg flexion and extension, left and right side turning over, reduces the incidence of common diseases such as bedsores and joint adhesion, and solves the nursing problem of the old people.

A few developed countries such as Europe, America and Japan have earlier research and development on the multifunctional nursing bed, longer research and development time, more reasonable mechanical structure design and more complete functional configuration. With the long development, the foreign branch enterprises have been able to mass-produce multifunctional nursing beds, such as panasonic corporation and octameng corporation in japan, StrykerMedical corporation and Hill-rom corporation in the united states. At present, high-end intelligent nursing beds are mainly developed abroad by using sensor technology, internet technology and advanced technology products.

A multifunctional nursing bed capable of being converted from a bed to a wheelchair is designed for common bedridden patients with dyskinesia of lower limbs and incapability of independently getting on and off the bed and walking indoors by various foreign scientific research institutions. Meanwhile, the nursing bed is also provided with other partial auxiliary functions, and the patient can correspondingly select according to the actual demand degree of the patient.

The nursing bed in China is still in an initial research stage, functions are not perfect enough, a large difference exists between the nursing bed and a foreign nursing bed, comfort level, safety degree, reliability and the like of users during use need to be improved, turning-over and defecation treatment are not intelligent enough, and a part of nursing beds only design simple turning-over actions and only rely on a whole bed board to turn over and cannot meet requirements of users with different body types.
