Description

Atomizing cup

Technical Field

The utility model relates to an atomizing cup.

Background

A nebulizer is a medical device that atomizes a liquid such as a medicine to form an aerosol. The atomized medicine aerosol is inhaled from mouth and nose to enter trachea, bronchus and lung of patient, and directly applied to the treatment part to achieve good treatment effect, and is commonly used for treating respiratory diseases.

The air compression type atomizer generally comprises an atomization generator, a mist suction mask, an atomizing cup and a connecting pipeline, wherein the atomizing cup is an important part of the air compression type atomizer and is connected with an atomizer host, and the medicine liquid in the cup is atomized into aerosol particles with micron-sized diameters under the combined action of the structure of the atomizing cup and the atomizer host, so that a patient can inhale the aerosol particles.

The effective atomized particle diameter is the diameter of atomized particles which can be deposited in the air passage and lung and have therapeutic value, and should be 0.5-10.0 μm, preferably 3.0-5.0 μm. The particles with different diameters are deposited on various parts of the respiratory tract, the atomized particles with the diameter larger than 10 mu m usually only stay in the oral cavity, the nasal cavity and the pharyngeal portion, 5-10 mu m can reach the first 6 grades of bronchus, and 1-5 mu m can reach the tail end of the lung.

The problems generally existing in the prior art are as follows: the diameter of the aerosol particles atomized by the atomizing cup can not be ensured to be stable. The atomizing part structure of the atomizing cup is generally composed of a liquid medicine groove, a nozzle, a water suction pipe and a stop block, compressed air is discharged through the nozzle, negative pressure is formed between the nozzle and the water suction pipe in the sealed cup body, liquid medicine in the liquid medicine groove is sucked to a nozzle opening and is contacted with the compressed air to be sprayed to the stop block and the wall surface of the cup to form mist, and the size of aerosol particles after atomization cannot be accurately controlled by the arrangement mode. Therefore, aerosol particles inhaled by patients are inconsistent in size and cannot be accurately applied to the treatment part, and the treatment effect is reduced.
