Title:
PORTABLE PRECISE VISUAL ATOMIZATION DELIVERY DEVICE BASED ON SURFACE ACOUSTIC WAVE TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2023/108316
Kind Code:
A1
Abstract:
A portable precise visual atomization delivery device based on surface acoustic wave technology, comprising a housing (1), an atomization chip (2), and a drug delivery apparatus. An atomization cavity (3) is provided in the housing (1), and the atomization cavity (3) has the upper portion connected to a breathing mask (4), and the lower portion connected to an air inlet pipe (5); the drug delivery apparatus comprises a drug storage portion, the drug storage portion comprising a storage bottle (6), a drug delivery valve (7), and a drug outlet pipe (8); the atomization chip (2) is used for atomizing a liquid medicine released by the drug delivery apparatus, and comprises a piezoelectric single crystal substrate (9), an interdigital transducer (10) provided on the piezoelectric single crystal substrate (9), a PCB (11) and a signal interface (12). A drug can generate quantitative, uniform and stable atomization by means of surface acoustic wave technology, a user can autonomously control an atomization amount and an atomization particle size by means of an external display and a control panel, thereby facilitating the visual observation of dosage and adjusting the dosage to control the apparatus.
