Medical vaporizer

Abstract

The invention discloses a medical vaporizer comprising 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 exhaust port in the shell through the corrugated pipe; and a drying device is arranged in the mist exhaust port. The medicine cup, the water tank, the ultrasonic generator and thecentral control device are all arranged in the shell. The medicine cup is arranged above the water tank, and a sound transmission film is arranged at the bottom of the medicine cup; the ultrasonic generator is arranged below the water tank; the central control device that is arranged below the ultrasonic generator and is electrically connected with the ultrasonic generator is used for driving andcontrolling the ultrasonic generator. A side door is arranged on one side of the shell, and the size of the side door matches that of the medicine cup. A baffle plate is arranged on one side, far away from the mist exhaust port, above the medicine cup; and a flow guide plate is arranged in the shell and above the mist exhaust port at a certain angle. The medical vaporizer provided by the invention is good in atomization effect and low in cost.

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
