Medical atomizer

Abstract

The invention discloses a medical atomizer. The medical atomizer includes a shell, a medicine cup, a water tank, an ultrasonic generator, a central control device, a corrugated pipe and a nasal mask;the nasal mask is connected with a mist discharge opening in the shell through the corrugated pipe; a drying device is arranged in the mist discharge opening; the medicine cup, the water tank, the ultrasonic generator and the central control device are all arranged in the shell; the medicine cup is arranged above the water tank, and the bottom of the medicine cup is provided with an acoustic transmission membrane; the ultrasonic generator is located below the water tank; the central control device is arranged below the ultrasonic generator and is electrically connected with the ultrasonic generator for driving and controlling the ultrasonic generator; a side door is arranged on one side of the shell; one side, located above the medicine cup and far away from the mist discharge opening is provided with a baffle; the part, located above the mist discharge opening, of the interior of the shell is provided with a flow guide plate at a certain angle; an air blowing device is arranged abovethe baffle, and the air blowing device is used to blow an atomized medicine liquid to the mist discharge opening. The medical atomizer provided by the invention has a good atomization effect and a lowcost.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a medical nebulizer. Background technique [0002] Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lung deposition through inhalation, so as to achieve painless , The purpose of rapid and effective treatment. Medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as colds, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli, and chest cavity. A good atomizer needs to have the characteristics of stable spray, small, uniform and high atomization efficiency. [0003] The ultrasonic nebulizer uses ultrasonic sound energy to turn the medicinal li...

Problems solved by technology

[0004] At the same time, although the mist particles produced by the ultrasonic nebulizer are large and the atomization is fast, it can quickly enter the treatment state; but at the same time, it will bring too much water vapor

If the patient inhales too much water vapor, the dry and thick secretions in the respiratory tract that partially blocked the bronchus will expand after absorbing water, increasing the resistance of the respiratory tract, which may cause hypoxia and lead to poor treatment experience; more seriously, If a large amount of water enters the patient's lungs, it may also cause fluid to accumulate in the patient's lungs

In addition, the ultrasonic nebulizer will cause the liquid medicine to form water droplets and hang on the wall of the inner cavity, resulting in waste of medicine and increasing the cost of medicine
