DEVICE FOR DRUG INJECTION WITH ROTARY ENCODER Russian patent published in 2022 - IPC A61M5/24 

FIELD: medical equipment.

SUBSTANCE: present invention relates to medical equipment, namely to devices for drug injection. According to the first aspect, in the present invention, an injection device is described, containing: a movable dosage programming component containing a rotary encoder system with a set angular periodicity; a sensor node containing the first optical node made with the possibility of detection of movement of the movable dosage programming component relatively to the sensor node during drug dosing, wherein the first optical sensor is made with the possibility of operation in a strobe sampling mode at the first frequency; the second optical sensor made with the possibility of detection of movement of the rotary encoder system relatively to the second optical sensor, wherein the second optical sensor is made with the possibility of operation in a strobe sampling mode at the second frequency less than the first frequency; and a processor device made with the possibility of determination of a drug dosage injected by the injection device, based on the specified detected movement.

EFFECT: obtaining a device for drug injection with a rotary encoder.
