Description

A rib support mechanism and a microenvironment adjustment mechanism with adjustable softness and hardness, and improved Relief bed for sleep microenvironment

technical field

The utility model relates to the field of furniture, in particular to a rib support mechanism with adjustable softness and hardness, and a pressure-releasing nursing bed capable of improving sleep microenvironment.

Background technique

Sleep is the guarantee of human energy and physical recovery, and the unreasonable pressure distribution of the human-bed interface will affect human sleep health. When the pressure distribution at the human-bed interface is uneven, the excessively concentrated pressure distribution will cause the local muscle and soft tissue to be overcompressed and cause ischemia. Human body posture adjustment and action behavior, thereby increasing physical energy consumption and affecting people's sleep continuity. In addition, the pressure of human venules is 4.00KPa (30mmHg), and the pressure of arterioles is 3.3-4.6KPa (25-35mmHg). And the duration of 1-2 hours can block the perfusion of capillaries to the tissue, causing tissue hypoxia. If it is compressed for more than 2 hours, it will cause irreversible tissue damage. -48h pressure ulcers will occur. For people who are bedridden for a long time or who cannot move due to injury, it is usually impractical to perform regular movements to turn over when the pressure is too high. Under the dual influence of the load action time and action intensity, it is more likely to lead to the formation of pressure ulcers. Therefore, pressure relief is the primary feature of nursing beds that such people need to use.

At present, most of the nursing beds on the market are air mattresses, which use the airbag to inflate and deflate alternately to change the pressure part of the person, so as to increase the air circulation of the diseased part, promote blood circulation, and reduce complications such as pressure ulcers. The air permeability of the bed is poor, which is not conducive to the air circulation inside the mattress, and the air bag has high hardness, which is easy to cause a large local pressure on the human body. In order to reduce the pressure time, it is necessary to frequently inflate and deflate, which will affect the Sleep continuity, reducing sleep comfort. Although the memory foam mattress on the market has a good pressure-relieving effect, the memory foam is a petrochemical product and is a non-renewable resource. Moreover, the memory foam has poor gas properties and poor permeability. It is easy to breed mites and bacteria over a long period of time, which is not conducive to the human body. Sleep healthy.

In addition, studies have shown that people are most likely to fall asleep when the temperature of the human-bed interface is 28°C to 32°C and the humidity is 50% to 65%, and the body temperature changes rhythmically every night when people sleep. Falling and then rising, the body temperature of the limbs will first rise and then return to normal, which means that the mattress needs good heat and moisture removal performance. If the moisture equivalent to 200-300mL of water is discharged by the human body every night and cannot be dissipated in time through the pillow and mattress, the bed surface and pillow surface are prone to wet and sticky feeling, which is not conducive to the comfort of the human body and the further discharge of the human body. Heat and moisture removal; at the same time, if the heat emitted by the person cannot be dissipated in time, and the temperature of the person-bed interface is too high, the skin moisture will be released faster, and the body will sweat too much, resulting in the loss of body water, and the bed surface will also When the temperature of the human-bed interface is further increased to the surface temperature of the human body, the temperature control mechanism of the human body is out of balance, and the human body will have a heat stress response, that is, fever. At the same time, studies have shown that moist skin is five times more likely to develop pressure ulcers than dry skin, and any increase in temperature when tissue ischemia is caused by continuous pressure will also increase the tissue's susceptibility to pressure ulcers. In order to obtain a good sleep microenvironment, temperature and humidity regulation is very important, and temperature and humidity regulation must involve temperature and humidity monitoring. The accuracy of traditional temperature and humidity sensors is ±0.3-0.5°C for temperature and ±3-5% for relative humidity. Low, it is impossible to monitor the subtle temperature and humidity changes inside the mattress due to changes in body temperature during sleep and human body dehumidification. sleep needs.
