Description

A flexible turning nursing wheelchair bed

technical field

The invention relates to the technical field of medical equipment, in particular to a flexible turning nursing wheelchair bed.

Background technique

According to statistics from the National Health Commission, my country currently has a population of nearly 250 million people aged 60 and over, and more than 40 million disabled elderly people. The aging situation is grim. The elderly will suffer from different senile diseases such as high blood pressure, cerebral thrombosis, and Parkinson's syndrome due to the decline of body immunity in old age. Most diseases require long-term bed rest. The care of the elderly during bed rest becomes the responsibility of their children. big problem. Long-term bed rest will put pressure on the back, buttocks and back of the legs of the patient, resulting in blood clogging in a certain part, resulting in insufficient blood supply. In mild cases, the skin will be blue and purple, and in severe cases, it will lead to malnutrition and skin necrosis in this part, resulting in Bed sores, the occurrence of bedsores can aggravate the patient's pain and lead to wound infection. The traditional nursing method is to accompany the patient's family members to turn over regularly, but the nursing is unprofessional, time-consuming and labor-intensive, which is not suitable for most ordinary families. Therefore, the multifunctional turning nursing bed can be developed. The multifunctional turning nursing bed is a medical bed that can assist patients to turn over, bend their legs, support their back, etc. In order to solve the aging problem that our country is about to face, the state strongly supports the research of medical care equipment by various enterprises and relevant scholars, increases the research on medical equipment, improves the scientific and technological innovation ability of medical equipment, and focuses on the development of high-performance medical equipment such as medical robots became the top priority.

Medical beds on the existing market are mainly divided into three categories. The first category is the most traditional medical bed, which can only be used for rest without any other functions. The second category is a manual nursing bed, which supports the back and bends the legs manually. The third category is the multi-functional turning nursing medical bed developed based on sensor technology, ergonomics, microelectronics technology, new material technology and intelligent network. This kind of bed has relatively high technological content, complete functions, and basically realizes electrification. .

However, the multifunctional nursing wheelchair beds currently on the market have complex structures, and many wheelchair beds are inconvenient to move, or have average stability when standing upright, resulting in poor user experience. Based on this, we propose a flexible turning nursing wheelchair bed.
