Description

System for adjusting breathing microenvironment

Technical Field

The utility model relates to a system for adjust and breathe microenvironment belongs to human microenvironment technical field.

Background

During the rest period, especially the sleep period, of the human body, the vegetative nerves usually mainly excite parasympathetic nerves; the heart rate and the respiration become slow, skeletal muscle is relaxed, the metabolic rate is reduced, the body temperature is reduced, the diameter of a bronchoconstrictor tube is reduced, the blood supply of heart coronary arteries is reduced, the blood volume of skin microcirculation is reduced, the secretion of respiratory mucus is reduced, the cilia swing of trachea and bronchial epithelium is weakened, and the immunity and the comprehensive resistance are reduced.

The breathing microenvironment of a human body in a bedridden state is generally only the transition of indoor and outdoor environments in a region close to the mouth and nose of the human body, and the influence of the gas quality of the external environment on the breathing microenvironment of the human body is great in an open state.

When the user sleeps, the head and the face of the human body are usually exposed and sensitive to various influence factors of ambient air, and the skin heat balance is interfered to influence the cell metabolism when the air flow temperature is too high or too low; excessive air moisture can affect the onset of non-perspiration, while too little moisture can cause dehydration of the respiratory tract and facial skin to varying degrees.

The respiratory system of the human body is a system which is completely open to the ambient air, and pathogenic factors in the ambient air such as pollen, dust mites, mould fungi, various particles in the air, formaldehyde and other harmful gases can cause more serious injury to the human body than when the human body is awake during the sleep period when the respiratory system defends the most vulnerable sleep; asthma, COPD, apnea, myocardial ischemia, and other disorders are more prone to attack during sleep.

The door and window are usually closed in the indoor sleeping process, the carbon dioxide generated by human metabolism is continuously exhaled to ensure that the indoor concentration is gradually increased to more than 1000PPM from 350PPM close to the atmosphere, and the indoor concentration is harmful to patients with weak functions of various systems of the human body to a certain extent, especially more harmful to patients with asthma and cardiac insufficiency.

Even in the environment that the whole house purifies, individualized sleep still needs the gaseous condition of breathing microenvironment constantly to adjust in the sleep process, and corresponding adjustment should be made along with the time phase difference of sleep to wind speed, temperature, humidity, and the air parameter control of whole house is difficult to in time satisfy sleeper's demand.

In addition, the shape and hardness of the pillow body for bearing the head and neck can obviously influence the sleep; stronger light, less negative air ions and bad smell can obviously reduce the sleep quality.

Waking from sleep also requires the environment to change synchronously, like dawn light waking in a human historical long-term or sound waking accompanied by a similar rooming sound.

In addition, the body position of the human body can be changed unconsciously during sleeping, so that the individualized optimal sleeping posture is difficult to maintain, for example, a patient with a thoracic cavity disease should lie on the affected side as little as possible.

Physical recovery, growth and development, mental rest, immunity regulation and disease rehabilitation of human depend on sleep quality seriously, and an individualized sleep breathing microenvironment is a key for ensuring good sleep.

CN102859288B discloses a concept of preventing the external ambient air from being mixed by providing a clean flow of breathing air with a temperature slightly lower than the external ambient temperature to the breathing microenvironment, so as to ensure the breathing microenvironment is stable, but the person may turn over unconsciously during sleep, for example, the breathing microenvironment is easily polluted by the external air flow without systematic constraint.

CN105617564A proposes to release clean respiratory airflow from two opposite directions of human respiratory tract opening to ensure stability of microenvironment, but these two airflows have multiple escape directions after colliding with each other, and easily mix exhaled carbon dioxide and the like into turbulent flow after colliding with human exhaled airflow, and the upward open space is far away from claustrophobia but also makes external air easily mix in.

CN101033882A emphasizes that the target temperature of the air conditioner affecting the human body temperature during sleeping should be individually set to meet the environmental temperature requirements of the human body in different sleep stages, and the air conditioner temperature is directly connected with the human body temperature without any buffer, which is difficult to meet the requirements on the human body microenvironment during sleeping.

It is well known to those skilled in the art that the above embodiments do not use the rolling bearing B but the two are directly connected in rotation.

Example 3:

as shown in fig. 3A and 3B, the difference from embodiment 2 is that the air conditioning module 2 and the system control module 21 are located in the connected housing 4, the guide module 3 is composed of a guide module horizontal part 31 and a guide module vertical part 32, the periphery of the guide module 3 is integrated with the housing 4, and the guide module may be integrally formed or may be formed by connecting independent modules; the connection region 41 of the guide module 3 to the housing 4 can be a flexible transition, optionally made of a flexible material such as silicone rubber, polyurethane, etc.

The guide groove 33c is positioned on the guide module horizontal portion 31, and the guide module vertical portion 32 is provided with a guide hole 320; the guide gear 14d of the helmet body 11 is engaged with a guide rack 33d (not shown) of the horizontal portion 31 of the guide module, so that the helmet body 11 does not slide or move up in the left and right directions during rolling.

The system control module 21, the carbon dioxide processing unit 23, the harmful gas processing unit 24, the primary and intermediate efficiency particulate matter filtering component 251, the fan 30, the high efficiency particulate matter filtering component 252, and the temperature and humidity control unit 26 are all located in the shell, the power button 20 and the display 22 are exposed from the shell 4, and air in the external environment sequentially passes through the air conditioning units, enters the connecting passage 15, and then flows into the inner cavity 110 of the helmet body through the air conveying unit 16 in the helmet body 11.

Due to the integrated design, the whole system can be completely arranged on a bed, the difficulty that the air conditioning module 2 is independently arranged on the ground and the left and right direction matching needs to be considered is reduced, and the difficulty of system assembly and carrying is greatly reduced; the length of the connecting passage 15 is also greatly shortened, reducing the resistance of the entire airway. Meanwhile, the air conditioning module 2 in the shell 4 is higher than the helmet body 11, so that the space in the vertical direction is utilized to the maximum extent, the thickness and the length of the whole system are reduced, and the occupied area of the bed surface of the product is reduced to the minimum.
