Description
Technical Field
The invention relates to the field of atomization devices, in particular to a mouth suction type atomizer.
Background
With the increasing global environmental pollution, the number of respiratory tract disease patients is increasing, especially the outbreak of infectious diseases such as SARS, new coronavirus and the like, which seriously affect the life safety and normal life of people, and the atomization mode for treating respiratory tract diseases represented by new coronary pneumonia is a very effective treatment method. The principle of the treatment mode is that a medical atomizer is used for atomizing treatment liquid medicine, the liquid medicine enters the lung of a patient through autonomous respiration or mechanical ventilation assistance of the patient and is absorbed by the body of the patient, and the purpose of treating respiratory diseases is achieved. The performance of the atomizer is of great importance, the size of the fog particles determines the sedimentation position of the medicine in the respiratory tract, the fog particles above 3.5 microns can only sediment in the upper respiratory tract, the fog particles below 3.5 microns can only enter the lower respiratory tract, and the smaller the fog particles, the more the quantity of the fog particles entering the lower respiratory tract, the more beneficial the treatment effect can be achieved by using the least amount of the medicine. Currently, there are two main types of medical nebulizers: ultrasonic atomizers and air compression atomizers.
1. The ultrasonic atomizer atomizes liquid medicine by utilizing an ultrasonic principle, and mainly has the following defects:
(1) the diameter of the atomized particles is larger, generally 3.5-5 microns, most of the generated medicine particles can only be deposited on upper respiratory tract parts such as oral cavity, throat and the like, the deposition amount in the lung is very small, and the lower respiratory tract diseases cannot be effectively treated;
(2) the large fog particles and the fast atomization result in excessive water vapor inhaled by a patient to humidify a respiratory tract, the thick and dry substances originally blocking the bronchus in the respiratory tract expand after absorbing water by mistake to increase the resistance of the respiratory tract, and the oxygen deficiency phenomenon is possibly generated;
(3) the atomization amount is small, the medicine demand is large, and the waste of the liquid medicine is caused.
2. The air compression atomizer is according to the venturi injection principle, utilizes compressed air to form the negative pressure that high-speed air current produced through tiny mouth of pipe, drives liquid and sprays to the obstacle together, splashes to around under the high-speed striking, makes the liquid drop become behind the vaporific particle from the outlet duct blowout, and it mainly has following shortcoming:
(1) the mist particles, although smaller than that of ultrasonic atomization, are not smaller than 1 micron;
(2) more liquid medicine is needed for atomization, so that waste of the liquid medicine is caused;
(3) the air compressor is needed, the equipment is large in size and cannot be portable, and the compressor can generate noise during working, so that the normal rest of a patient is influenced.
3. When atomization resources in hospitals tend to be saturated, due to the fact that atomization equipment is heavy and expensive, the fact that each patient is dedicated to a person special for the atomization equipment cannot be achieved, and in addition, cross infection is high in risk when the patient goes to a hospital for treatment, a plurality of early slight or asymptomatic infected persons cannot be treated and diagnosed in time, and only can be isolated at home, and finally severe pneumonia is delayed to develop.
4. Whether the ultrasonic atomizer or the air compression atomizer is adopted, most of the ultrasonic atomizer or the air compression atomizer is not provided with a heating device, the temperature of generated fog particles is low, the ultrasonic atomizer or the air compression atomizer is inconvenient to use in north or cold weather, and the cold liquid medicine not only reduces the atomization amount of atomization, but also seriously influences the comfort of a patient in the inhalation process, and even can cause certain damage to the airway of the patient; a small amount of inventions relate to heating atomization, but most of the inventions do not set a temperature control mode, heating temperature and constant temperature are designed through a fixed program generally by designing heating element power and current, the precision is generally more than +/-10 degrees, so that the decomposition and the failure of the medicine are caused, and in addition, the temperature of the medicine steam generated by heating is higher, and the medicine steam is directly inhaled into a respiratory tract and can damage epidermal cells.
5. The control system and the liquid storage cavity of most products have liquid leakage, some products are added with liquid blocking sheets made of nylon and the like, so that liquid is prevented from flowing into the control system, and harmful substances are easily generated at high temperature.
6. Many products have organic material accessories such as oil guide ropes, rubber parts and the like, and harmful substances are possibly generated under the heating condition, so that the product is not healthy and environment-friendly.
