Portable atomizer capable of automatically adjusting atomization rate according to lung flux

Abstract

The invention discloses a portable atomizer capable of automatically adjusting the atomization rate according to the lung flux. The atomizer comprises a casing, a liquor tank, a nozzle, a battery arranged in the casing, a circuit board arranged in the casing, an atomizing piece disposed between the liquor tank and the nozzle and an atomizing driving circuit arranged between the liquor tank and thecasing and respectively connected with the atomizing piece and the circuit board. The circuit board includes a main control module connected to the atomizing driving circuit, a lung flux detection module connected to the main control module and a digital display module and a power supply module which are connected to the main control module. The lung flux detection module includes a signal amplifying circuit connected to the main control module and an internal resistance strain sensor connected to the signal amplifying circuit. The nozzle is provided with a blowing channel spaced apart from the nozzle and extending from the outside to the inside. The blowing channel is communicated with the inside of the casing, and air in the blowing channel enters the inside of the casing to be in contact with the internal resistance strain sensor. The portable atomizer has the advantage of being convenient to use and environmentally friendly.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a portable atomizer that can automatically adjust the atomization rate according to the lung flux. Background technique [0002] Nebulized inhalation therapy is an important and effective treatment method in the treatment of respiratory system diseases. The nebulizer is used to atomize the liquid medicine into tiny particles, and the patient breathes the aerosolized medicine into the respiratory tract and lungs, and deposits them. Absorbed through the mucosa, so as to achieve the purpose of painless, rapid and effective treatment. However, pulmonary ventilation refers to the amount of gas entering and exiting the lungs per unit time, which reflects the ventilation function of the lungs. The size of the pulmonary ventilation is also an important factor affecting the effect of aerosol therapy. For example, when the user suffers from asthma or other conditions such as cough, the ...

Problems solved by technology

Therefore, when the amount of mist is too large, the patient cannot fully absorb it, resulting in a waste of liquid medicine

Moreover, the liquid medicine flowing out from the nozzle will also irritate the patient's eyes and other sensitive organs of the human body, and even cause certain pollution to the surrounding environment; when the user's lung ventilation volume is large and the amount of mist produced is too small, the therapeutic effect cannot be achieved.

Therefore, there are defects that the amount of atomization cannot be automatically adjusted according to specific usage conditions, causing inconvenience and affecting the surrounding environment.
