Description

A bionic body position adjustment bed based on multi-point molding principle

Technical field

The invention relates to the field of bionics, and in particular to a bionic body position adjustment bed based on the multi-point molding principle.

Background technique

At present, in the social group structure, groups with difficulty or inability to move independently account for a considerable proportion. The following takes the ultrasound examination scenario and the daily care of the elderly as examples:

Ultrasound examination is a modern conventional medical method. During the examination, the patient cooperates with the doctor to stand up, roll over, lean to the side, bend the legs and other operations. Usually, in order to facilitate the doctor's better examination, the patient is required to check the direction and amplitude of the position change. For minor adjustments, for groups who rarely undergo ultrasound examinations, the elderly, or some disabled groups, it often takes longer to make position changes that meet the requirements of the examining physician. The existing ultrasonic examination bed board is only a narrow bed board. Patients cannot clearly understand the direction and amplitude of activities such as turning over and sideways on it. Communication barriers with doctors and self-movement barriers will affect the examination efficiency.

According to statistics at the end of 2016, China's elderly population over 60 years old accounted for 16.7%; in 2040, the population of this group may exceed 397 million. According to expert estimates, the aging problem will affect China's future family structure in many ways. With the transformation of the country, the issue of care for the elderly is very prominent. Patients lying on the hospital bed usually need to regularly complete body posture requirements such as turning sideways, turning over completely, and tilting forward and backward to prevent bedsores. The existing air mattress hospital beds have a single function and only have the function of simulating bedsores. Currently, other hospital beds with body position changing devices on the market mostly use a rotating composite bed board to change body positions. Although this method is simple to implement, its comfort and coordination with the human body are poor.

In response to the above situation, body position changing beds have been produced. According to the driving mode, the current body position changing bed devices are mainly divided into two categories on the market:

One type is a manual, single-function, mobile-turning hospital bed. This type of hospital bed is mainly used in ICU wards of ordinary hospitals. This type of hospital bed can be driven by human power and use traditional mechanical transmission mechanisms to control the backboard and legboards to complete simple operations. The dorsi-flexed leg state has no lateral tilt or roll function;

The other type is electric hospital beds. This type of hospital bed can use electricity to drive each actuator based on a simple control system, replacing human power with electricity. The original design of this type of hospital bed is to reduce the labor intensity of the operator.

Both of the above-mentioned hospital beds adopt a folding bed board position-changing solution. This solution has advantages and disadvantages. It is worthy of recognition for its simple structure to achieve functional requirements. However, the above-mentioned products ignore the comfort of human-machine equipment on the human body and the bionics of the equipment itself. As a device that is in direct contact with the human body, the way the device achieves its expected functions should try to imitate the behavioral characteristics of the normal human body. For example, when assisting a patient to turn over, the actuator is not a bed board but a device that imitates a human hand. The device can bend while turning over. Legs, use proper force on the hips when sitting up, etc.
