POWDER INHALER ASSEMBLY Russian patent published in 2024 - IPC A61M15/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely to a powder inhaler assembly, an electronic module for a powder inhaler and a powder inhaler. Assembly comprises powder inhaler (2) containing container (8) for storing the powdered medicament, mouthpiece (6), inhalation channel (9) connected to mouthpiece (6) and measuring device (10) having dosing recess (11). Measuring device (10) is configured to move relative to container (8) and inhalation channel (9), between an inoperative state, in which dosing recess (11) is in communication with opening (12) of container (8) so as to be filled with a dose of the powdered medicament, and an initiated state in which dosing recess (11) is in communication with inhalation channel (9) to enable inhalation of a dose of the powdered medicament contained in dosing recess (11) through mouthpiece (6). Assembly has electronic module (3), for connection to powder inhaler (2), containing contactless sensor (29), located and configured, to detect the position or positions of measuring device (10), to detect when measuring device (10) is in an initiated state. Electronic module, container (8) for storing powdered medicament, mouthpiece (6), inhalation channel (9) connected to mouthpiece (6) and measuring device (10) having dosing recess (11). Powder inhaler comprises container (8) for storing powdered medicament, mouthpiece (6), inhalation channel (9) connected to mouthpiece (6), and metering device (10) having dosing recess (11), as well as housing (4) having window (23). Container (8), inhalation channel (9) and measuring device (10) are arranged in housing (4). Measuring device (10) is visible through window (23) of housing (4). Powder inhaler (2) is made with possibility of connection to electronic module (3) containing optical proximity sensor (29).

EFFECT: providing a powder inhaler assembly equipped with an electronic module, which is adapted to detect movement of mechanical parts of the powder inhaler in order to assume dosage of a drug in a safe and reliable manner.
