Description
Technical Field
The invention relates to a medical atomizer, in particular to a nasal inhalation administration instrument for volatile liquid medicine.
Background
At present, the known medical atomizer is mainly used for treating various upper and lower respiratory diseases, such as common cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases occurring in the trachea, bronchi, alveoli and chest. The aerosol inhalation treatment is an important and effective treatment method in the treatment method of respiratory diseases, the liquid medicine is atomized into tiny particles by adopting an aerosol cup, and the medicine enters the respiratory tract and lung to be deposited in a respiratory inhalation mode, so that the purposes of painless, rapid and effective treatment are achieved, and three types of medical atomizers are available, namely an ultrasonic atomizer, a compression atomizer and a net type atomizer.
The sprayer of the ultrasonic atomizer has no selectivity to fog particles, so most of the generated medicine particles can only be deposited on the upper respiratory tract of the oral cavity, the throat and the like, and the lower respiratory tract diseases can not be effectively treated due to the small deposition amount of the lung. Meanwhile, as the fog particles generated by the ultrasonic atomizer are large, the atomization is quick, so that a patient inhales excessive steam to moisten the respiratory tract, the dry and thick secretion which is originally partially blocked in the respiratory tract absorbs water and expands, the respiratory tract resistance is increased, the hypoxia phenomenon can possibly occur, the ultrasonic atomizer can enable the liquid medicine to be formed into water drops and hung on the inner cavity wall, the effect on the lower respiratory tract diseases is poor, and the particle diameter of aerosol generated by the ultrasonic atomizer is 3.7-10.5 mu m.
The air compression atomizer utilizes compressed air to form high-speed air flow through a fine pipe orifice, and the generated negative pressure drives the liquid medicine to be sprayed onto the obstruction together, so that the liquid medicine is splashed to the periphery under high-speed impact, and the liquid medicine is changed into mist particles to be sprayed out from an air outlet pipe. However, the time of inhalation should not exceed 20 minutes per inhalation, and if the blindness is too high, pulmonary edema or water poisoning may be caused. There is also the possibility of increasing respiratory resistance, and dyspnea is aggravated when inhalation of nebulization is completed for several hours, and besides vigilance to pulmonary edema, respiratory tract secretions may be aggravated by liquefaction, expansion and blockage. At the same time, respiratory tract reinfection should be prevented. Since the droplets can carry bacteria into the alveoli, there is a possibility of secondary gram-negative bacterial infection. Bacterial origin: infection of the oral cavity, upper respiratory tract and atomized liquid of the infant. Not only is the hygienic care of the mouth, nose and throat enhanced, but care is taken to sterilize the atomizer, the room air and various medical instruments.
Net type atomizer: the net type atomizer belongs to a latest type of atomizer, has the characteristics of both a compression type atomizer and an ultrasonic type atomizer, is a household medical atomizer for pediatric asthma patients, and is convenient to carry and use at any time and any place by utilizing micro ultrasonic vibration and a net type spray head structure, and in the net type atomizer, MDIs are the most common aerosol generating device applied at present, and the diameter of aerosol particles generated by the MDIs is about 3-6 mu m.
The medical atomizer is atomized by an atomizing cup, the diameter of particles of generated aerosol is in the range of 3-10.5 mu m, the diameter of the particles of the aerosol entering into respiratory bronchioles and lung areas is less than or equal to 3 mu m, the stable condition of atomization treatment is more required that the diameter of the particles of the aerosol is in the range of 0.3-0.7 mu m, and obviously, the particles of the aerosol generated by the existing medical atomizer are difficult to reach into the respiratory bronchioles and lung areas.
The atomizing cup has the problems of large volume, heavy weight and uncomfortable wearing for a long time.

2. The nasal inhalation administration device for volatile liquid medicine according to claim 1, wherein the bottom cover is connected with the bottle body through threads, and an O-ring is arranged between the bottom cover and the bottle body; the top cover is connected with the bottle body through threads, and an O-shaped sealing ring is arranged between the top cover and the bottle body.
3. The nasal inhalation administration device for volatile liquid medicine according to claim 1, further comprising a case, wherein the bottle, the air pump and the alarm control circuit are installed in the case.
4. A method of using a nasal inhalation delivery device for a volatile liquid drug according to any one of claims 1 to 3, comprising the steps of:
1) Injecting volatile liquid medicine into the bottle body through a medicine adding pipe until the volatile liquid medicine is not higher than the fence;
2) Opening the air pump, introducing compressed air from an air outlet of the air pump to the bottom cover through the air pipe to the air collection chamber of the bubble tray, dispersing the compressed air to the surface of the bubble tray through the fine holes to form a plurality of bubbles and entering the volatile liquid medicine until the bubbles rise to the liquid level of the liquid medicine, enabling volatile components in the liquid medicine to escape, passing through the fence, the microporous filter membrane and the filter membrane guard board together with the compressed air, and finally sucking the volatile components into the lung through the nasal cavity through the nasal oxygen pipe to finish the drug administration work;
3) When the microporous filter membrane is invalid or damaged, the liquid medicine has a chance to enter the air outlet channel, and the liquid medicine has conductivity to conduct the electrode I and the electrode II, so that the coil of the relay KA is electrified and acts, the normally closed contact A, B of the relay KA is cut off, the normally open contact A, C of the relay KA is communicated, the power supply of the direct current motor speed regulator is cut off, the air pump motor and the air pump stop working, and after the normally open contact A, C of the relay KA is communicated, the buzzer II works to remind people to process faults and avoid the liquid medicine from being connected into the nasal cavity;
4) When the microporous filter membrane is blocked, the pressure in the bottle body is increased to be dangerous, when the pressure is increased to a set value, the pressure switch is triggered, the movable contact X of the pressure switch is disconnected with the fixed contact Y of the pressure switch, the power supply of the direct current motor speed regulator is cut off, the air pump motor stops working, meanwhile, the movable contact X of the pressure switch is communicated with the fixed contact Z of the pressure switch, the buzzer I works, and people are reminded of processing faults.
