A hand-held micro-net atomizer and its application method

Abstract

The present invention provides a hand-held micro-net atomizer and its application method. The atomizer includes an atomization unit, a main control unit, and an anhydrous detection unit. The nozzle, the micro-mesh atomizing sheet is axially installed on the nozzle, so as to atomize the medicine liquid in the medicine storage part, the main control unit includes a connecting seat, a main body and a control module, and the connecting seat is arranged on the upper part of the main body , the atomization unit is detachably electrically connected to the connection seat, the anhydrous detection unit includes an anhydrous detection pole and an anhydrous detection contact, the anhydrous detection pole is installed between the medicine storage part and the connection seat, and the anhydrous detection contact is set On the connection seat, it can be electrically connected to the anhydrous detection electrode, the anhydrous detection electrode, the positive electrode of the micro-mesh atomizer, and the liquid in the drug storage part form a capacitor, and the control module can detect the capacitance of the capacitor through the anhydrous detection contact. It is used for judging whether the drug storage part is in a water-containing state or an anhydrous state.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a portable and usable hand-held micro-mesh atomizer and an application method thereof. Background technique [0002] With the continuous development of science and technology, medical devices in many fields are developing towards miniaturization and portability. Medical nebulizer is 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 . Aerosol inhalation therapy is an important and effective method in the treatment of respiratory diseases. The drug or water is dispersed into mist or particles suspended in the gas by the inhaler, and the drug enters the respiratory tract and lungs through inhalation. Partial deposition, so as to achieve the purpose of painless, rapid and effective tre...

AI Technical Summary

Problems solved by technology

[0003] At present, conventional medical nebulizers are compression nebulizers or ordinary ultrasonic nebulizers, which are basically relatively large in size and need to be placed on a desktop or a relatively stable work surface to work. At the same time, the network power is generally used as a power supply. It is inconvenient to move, due to the limitation of size and power supply, the atomizer cannot be used portablely

However, the relative noise of the compression nebulizer is relatively large when it is working, and the atomization particle size of the ordinary ultrasonic nebulizer is not small enough, which is not conducive to absorption treatment.

[0004] Due to the limitation of volume, the existing hand-held medical nebulizers often lack the early warning function of the water level. When the water is short of water, they will not stop working automatically. If the atomizer continues to vibrate without enough liquid, it will The loss of the atomizer reduces the service life of the atomizer, and it is easy to burn the circuit board, so the atomizer cannot be used for a long time

Moreover, the existing power supply mode of the atomizer is also relatively single, lacking a power indicator, and unable to inform the use of the atomizer in advance

[0005] On the other hand, the nozzle of the atomizer is in direct contact with the outside world. Whether it is before or after use, in order to avoid contamination, it is necessary to clean the nozzle of the atomizer. Cause cross-contamination, and the disease enters through the mouth, which is not conducive to treatment
