HANDHELD HIGH-FREQUENCY ULTRASONIC ATOMIZED WHOLE RESPIRATORY MEDICINE INTRODUCTION DEVICE

摘要

Disclosed is a handheld high-frequency ultrasonic atomized whole respiratory medicine introduction device, comprising a shell (1) with an air inlet (2) and a cover with a spray outlet (3). The shell (1) is provided with a medicine cup (4) having an atomizing sheet and an atomizing hood (9) located at the top part thereon and having a spray-discharging port (11), wherein a channel for fluid communication is formed among the air inlet (2), the spray outlet (3) and the spray-discharging port (11). A fan is also provided near the air inlet (2). The main body of a piezoelectric ceramic atomizing sheet (5) is made of a material with the following components (in weight percent): 63.3-68.3% of lead tetroxide; 14.2-15.3% of zirconium dioxide; 8.1-9.5% of titanium dioxide; 4.6-5.2% of strontium oxide; 1.5-1.8% of iron sesquioxide; 1.0-1.4% of stannic dioxide; 0.3-1.1% of manganese dioxide; 0.5-0.8% of cerium sesquioxide; 0.4-0.8% of niobium pentaoxide; and 0.3-0.7% of zinc oxide. The device has a small power consumption and volume, is easy to carry, has a relatively low cost and small atomized particles, and is suitable for whole respiratory medicine introduction and lower respiratory alveoli concentrated administration.
