Description

A kind of volatility medical fluid nasal cavity inhalation instrument
Technical field
The utility model relates to a kind of vaporizer more particularly to a kind of volatility medical fluid nasal cavity inhalation instrument.
Background technique
Currently, well known vaporizer is mainly used for treating various respiratory diseases up and down, such as flu, fever, cough It coughs, the trachea-bronchial epithelial cells such as asthma, abscess of throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis, alveolar, the disease occurred in thoracic cavity Disease.Atomization inspiration treatment is a kind of important and effective treatment method in respiratory system treatment, will using atomizing cup Medical liquid atomizing is at molecule, and drug enters respiratory tract and pulmonary deposition by way of breathing sucking, to reach painless, fast The purpose that speed is effectively treated, there are three types of vaporizer types, ultrasonic ultrasonic delay line memory, compression atomizer and net formula atomizer.
The sprayer of ultrasonic atomizer is to droplet non-selectivity, so the drug granule generated is largely only capable of being deposited on mouth The upper respiratory tracts such as chamber, throat, and since the deposition of lung is seldom, it cannot effectively treat lower respiratory illness.Simultaneously as The droplet that ultrasonic ultrasonic delay line memory generates is big, and atomization is fast, causes patient to suck excessive vapor, makes respiratory tract humidifying, respiratory tract Bronchial do after thick secretion absorbs moisture of interior original Partial Blocking expands, and increases resistance of respiratory tract, may generate anoxic Phenomenon, and ultrasonic ultrasonic delay line memory can make medical fluid form droplet to hang on internal chamber wall, ultrasonic mist ineffective to lower respiratory illness The particle diameter for changing the aerosol that device generates is 3.7-10.5 μm.
Gas compression formula Compressed air nebulization device forms high-speed flow by tiny nozzle using compressed air, and generation is born Pressure zone moves medical fluid and is ejected into obstruction together, splashes under high-speed impact around, medical fluid is made to become misty particle from outlet Pipe sprays.But each Neulized inhalation time is not to be exceeded 20 minutes, if blindness dosage it is excessive have cause pulmonary edema or water intoxication Possibility.There are also the possibility for increasing resistance of respiratory tract, and after Neulized inhalation complete a few houres, expiratory dyspnea aggravates instead, except vigilant Outside pulmonary edema, it is also possible to expand the event of obstruction exacerbation since airway secretions liquefy.It should prevent respiratory tract simultaneously to infect again.Due to Droplet can enter alveolar with bacterium, therefore be possible to secondary gram-Negative bacillus infection.Bacterial origin: infant oral cavity, the upper respiratory tract, The infection of atomized liquid.So not only to reinforce mouth, nose, pharynx hygiene care, it is also noted that atomizer, room air and various doctors Treat the disinfection of instrument.
Net formula atomizer: net formula atomizer belongs to a kind of latest type of atomizer, has both compression atomizer and ultrasound The characteristics of formula atomizer, spray pattern are to be sprayed head structure using small ultrasonic activation and net formula to be sprayed, be towards Family's vaporizer that asthma in children patient uses uses convenient for carrying whenever and wherever possible, and in net formula atomizer, MDIs is mesh Preceding to apply aerosol generating device the most universal, aerosol particles diameter caused by MDIs is about 3-6 μm.
Above-mentioned vaporizer is atomized by atomizing cup, and the particle diameter range of the aerosol of generation is in 3- Between 10.5 μm, and the mist particle diameter into respiratory bronchiole, lung area is less than equal to 3 μm, the stablizing bar of nebulae inhalation Part is even more to require the particle diameter of aerosol between 0.3-0.7 μm, it is clear that the aerosol that existing vaporizer generates it is micro- Grain is hard to reach in respiratory bronchiole and lung area.
And there are also volumes for atomizing cup greatly, heavy, wears very uncomfortable problem for a long time.
Utility model content
In order to which the particle for the aerosol for overcoming existing vaporizer to generate is hard to reach respiratory bronchiole and lung area Interior deficiency, and atomization cup volumes are big, heavy, wear very uncomfortable problem for a long time.The utility model provides one kind Volatility medical fluid nasal cavity inhalation instrument has preferable volatile feature for some drugs, compressed air is injected and is volatilized Property medical fluid in, compressed air generate bubble during rising, make the volatile component in medical fluid as bubble escapes together Out, lung cavity is sucked through nasal oxygen tube, achievees the purpose that treatment.
