Nasal aspirator is a tool for cleaning nasal cavity. It usually uses a certain pressure (or air bag nasal aspirator, or gravity, such as simple bottle and can type, or mechanical pressure, such as electric type) to send normal saline into the nostrils, flow through the nasal vestibule (the part exposed outside the head), paranasal sinuses and nasal passages around the nasopharynx, or discharge from one nostril or from the mouth. Through the above path, with the help of the bactericidal effect of normal saline and the impact of water flow, the accumulated pathogenic and pollutants in the nasal cavity are discharged, so as to restore the normal physiological environment of the nasal cavity, restore the self detoxification function of the nasal cavity, and achieve the purpose of protecting the nasal cavity.
In the eyes of many people, nasal irrigation may be terrible, but in fact nasal irrigation has a long history. It is one of the long-standing health care methods of Indian yoga and Taoism. The method is to scoop clean water with both hands, bend your head, inhale the water into your nostrils, and then spit out the water from your mouth, so as to remove the snot and dirt in your nose. This method sounds simple. In fact, it is extremely difficult to operate. If you are not careful, you will be choked. I believe many people have the experience of choking by water when swim. In China, nasal washing is rarely used, but Westerners have inherited the methods of yoga and Taoism and invented nasal washing device. In the past hundred years, the use of nasal aspirator in the West has never stopped. The history of nasal aspirator has also experienced a process from simple to complex. The nose washers that used to appear are: hand pressure rubber tube type, plastic bottle type, spray type, steam type and so on.
Through the anti-inflammatory and bactericidal effect of saline, saline nasal washing can remove a large number of allergens, bacteria, viruses and purulent mucus gathered in the nasal cavity, even in the nasal sinuses, give the nasal cavity a clean and refreshing environment, restore the function of nasal cilia and accelerate the recovery of health.
Nasal cavity is another important channel for human body to communicate with the outside world except oral cavity. In fact, it is used much more frequently than the mouth, because people need to breathe all the time. Because the environment around us is not pure. These impurities and harmful substances are blocked in the nasal cavity by the filtering function of the nasal cavity when inhaled into the human body, so that they can not enter the lungs. However, if these impurities and harmful substances are not cleaned in time and entrenched in the nasal cavity for a long time, they may produce more bacteria and cause nasal lesions. This is like a piece of clean land, If garbage is stacked there for a very long time, flies, insects and mice will be everywhere. Moreover, too much harmful substances in the nasal cavity will inevitably increase the load of nasal filtration function. Therefore, we should often remove the harmful substances in the nasal cavity, so that the nasal cavity will always have a clean environment, so that the nasal cavity can always operate normally, and other organs in the body can operate better.
