Description

Mouth suction nebulizer

technical field

The invention relates to the field of atomizing devices, in particular to a mouth-breathing atomizer.

Background technique

As the global environmental pollution continues to intensify, the number of patients with respiratory diseases continues to increase. The principle of this treatment method is to use a medical nebulizer to atomize the therapeutic liquid, enter the patient's lungs through the patient's spontaneous breathing or mechanical ventilation, and be absorbed by the patient's body , in order to achieve the purpose of treating respiratory diseases. Among them, the performance of the nebulizer is very important. The size of the mist particles determines the settlement position of the drug in the respiratory tract. The mist particles above 3.5 microns can only settle in the upper respiratory tract, and the mist particles below 3.5 microns can enter the lower respiratory tract. The smaller the amount that enters the lower respiratory tract, the more it is beneficial to achieve the therapeutic effect with the least amount of medicine. At present, there are two main types of medical nebulizers: ultrasonic nebulizers and compressed air nebulizers.

1. Ultrasonic nebulizer is to use ultrasonic principle to atomize liquid medicine, which mainly has the following disadvantages:

(1) The diameter of the mist particles is relatively large, generally 3.5-5 microns. Most of the generated drug particles can only be deposited in the upper respiratory tract such as the mouth and throat, and the deposition in the lungs is very small, which cannot effectively treat lower respiratory tract diseases. ;

(2) Due to the large mist particles and fast atomization, the patient inhales too much water vapor, which humidifies the respiratory tract, and the dry and thick substances in the respiratory tract that originally blocked the bronchi swell after absorbing water by mistake, increasing the resistance of the respiratory tract, which may cause insufficiency. Oxygen phenomenon, and the ultrasonic nebulizer will cause the liquid medicine to form water drops and hang on the wall of the inner cavity, which is not effective for the treatment of lower respiratory tract diseases;

(3) The amount of atomization is relatively small, and the demand for medicine is large, resulting in waste of medicine liquid.

2. The compressed air atomizer is based on the principle of Venturi injection, using compressed air to form a negative pressure generated by high-speed airflow through a small nozzle, driving the liquid to be sprayed onto the barrier together, and splashing around under the high-speed impact, making the droplet become It is sprayed out from the outlet pipe after being sprayed into mist particles, which mainly has the following disadvantages:

(1) Although the mist particles are smaller than ultrasonic atomization, they will not be smaller than 1 micron;

(2) The medicinal liquid that atomization needs is more, causes the waste of medicinal liquid;

(3) An air compressor is needed, and the equipment has a large volume and cannot be portable, and noise will be generated when the compressor works, which affects the normal rest of the patient.

3. When the nebulization resources in the hospital tend to be saturated, because of the bulky and expensive nebulization equipment, it will not be possible for each patient to use the nebulization equipment exclusively, and there is a high risk of cross-infection when going to the hospital for treatment. As a result, many early-onset mild or asymptomatic infections cannot be treated and diagnosed in time, so they can only be isolated at home, and eventually develop into severe pneumonia.

4. Whether it is an ultrasonic nebulizer or an air compressed nebulizer, most of them do not have a heating device, and the temperature of the mist particles produced is relatively low. It is inconvenient to use in the north or in cold weather. It will seriously affect the comfort of the patient during the inhalation process, and even cause certain damage to the patient's airway; there are also a small number of inventions involving heating atomization, but most of them do not have a temperature control method, usually by designing the heating element power, The magnitude of the current, the heating and constant temperature are designed through a fixed program, and the accuracy is generally above +/-10°, which leads to the failure of the drug to decompose. In addition, the temperature of the drug vapor generated by heating is high, and it is directly inhaled into the respiratory tract, which will cause damage to the epidermal cells.

5. There is liquid leakage between the control system and the liquid storage chamber of most products. Some products add a liquid blocking sheet made of nylon to prevent liquid from flowing into the control system, but harmful substances are easily produced at high temperatures.

6. Many products have accessories made of organic materials such as oil guide ropes and rubber parts. When heated, harmful substances may be produced, which is unhealthy and environmentally friendly.

In the structure of the present invention, the lower limit of the porous dispersion column 50 is performed by the position where the horizontal section meets the second vertical section, and the upper limit of the porous dispersion column 50 is performed by the one-way valve 60 arranged at the exhaust port of the air channel 104. position, thereby making the installation and disassembly of the porous dispersing column 50 easy, and after installation, the stability is good, and it is not easy to be displaced by the external airflow in the air flow channel 104, so the dispersion effect on the external airflow is good, and the external airflow can be formed uniformly and smoothly. Scattered micro air column.

Optionally, as shown in FIG. 1 , in the first specific embodiment of the present invention, when the volume of the atomizer of the present invention is small, the air intake port of the air passage 104 is provided with an induced draft fan 70, and the induced draft fan 70 Connected to the installation end 101 of the installation base 10 , the induced draft fan 70 is used to rotate under the action of the external airflow, so as to accelerate the external airflow to enter the atomization chamber 102 after passing through the air channel 104 .

When the person inhales, the air pressure detector will detect negative pressure. , the controller controls the heating member 30 so that it can be heated with high power to generate steam. At the same time, the external airflow passes through the porous ceramic column to form a micro-airflow into the atomizer, and the medicine vapor is taken away from the liquid surface in time to form an aerosol, that is When a little medicament vapor is generated, it will be taken away by the micro air flow in time to prevent the vapor from condensing inside the liquid or on the upper part of the liquid. In another embodiment, the heating member 30 is connected to the controller, and under the action of the controller, the heating member 30 continuously heats the medicine to generate medicine vapor during the whole medicine atomization process.

Preferably, the one-way valve 60 provided at the exhaust port of the air passage 104 is replaced with an electric control valve, and the electric control valve is connected to the controller, and the controller is used to control the opening of the electric control valve when the air pressure value is negative, so as to prevent When the volume of the atomizer is large, the amount of medicine in it is large, and the liquid column is relatively high, it is difficult to open the one-way valve 60 only by air flow. In a preferred solution of the present invention, the electric control valve is a solenoid valve.

Optionally, as shown in FIG. 1 , the number of air flow channels 104 is multiple, and the plurality of air flow channels 104 are sequentially arranged at intervals along the circumference of the atomization chamber 102 .
