AUDIO INDICATOR FOR A DRUG DELIVERY DEVICE Russian patent published in 2020 - IPC A61M5/20 A61M5/24 A61M5/32 

FIELD: medicine.

SUBSTANCE: group of inventions relates to a drug delivery device and to a method of assembling such a device. Housing and resilient pressure element are provided. Bending pressure element relative to longitudinal bending and thus dividing pressing element into two padded sections located at an angle to each other, bringing pressure element into first configuration. Elastic deviating of pressure member relative to axis extending perpendicular to longitudinal bend, and thereby the pressure element is transferred from the non-stressed state into the deflected state, thereby driving the pressure member into the second configuration. Pressure element is inserted into the body. Device comprises a mechanical audio indicator for generating an audio signal with a loudness level of 100 dB.

EFFECT: reliable signaling and notification on completion of drug delivery for users with hearing impairment.
