DRUG DELIVERY CONTROL Russian patent published in 2024 - IPC A61M5/50 A61M5/20 

FIELD: medicine.

SUBSTANCE: invention relates to the field of medical equipment, namely to a device for administering and/or delivering a drug, to a system in which the device can be used, and to a method of administering, and to an additional method associated with the system. Drug delivery device comprises a drug holder, a first sensor, a second sensor, a memory device and a processor. Drug holder is configured to hold a drug therein. First sensor is configured to collect data on a first characteristic associated with a patient. Second sensor is configured to collect data on a second characteristic associated with the patient. Memory device is configured to store an algorithm in it, which includes at least one variable parameter. Processor is configured to control the delivery of the first dose of the drug from the drug holder to the patient by executing an algorithm, changing at least one variable parameter of the algorithm stored in the memory based on data collected by the first sensor, and data collected by a second sensor in a hierarchy prioritizing data from one of said first and second sensors over the other, and controlling the delivery of the second drug dose from the drug holder to the patient by executing an algorithm after changing at least one variable parameter. Method of administering a drug involves collecting data using a first sensor with respect to a first characteristic associated with a patient; collecting data using a second sensor with respect to a second characteristic associated with a patient; using a processor for: controlling the delivery of a first dose of a drug from a device for administering a drug to a patient by executing an algorithm stored in the memory, changing at least one variable parameter of the algorithm stored in the memory based on data collected by the first sensor, and data collected by a second sensor in a hierarchy prioritizing data from one of said first and second sensors over the other, and controlling delivery of a second dose from the drug delivery device to a patient by executing an algorithm after changing at least one variable parameter. According to the second embodiment, the drug delivery device comprises an auto-injector, and the first sensor and the second sensor are configured to collect data on the angular position of the auto-injector relative to the patient's skin. According to a third embodiment of the drug delivery device, the first sensor is configured to collect data on the patient’s physiological characteristic, and the second sensor is configured to collect data on the physical characteristic of the patient. According to a second embodiment, a method of administering a drug comprises collecting data using a first sensor with respect to a physiological characteristic associated with a patient; collecting data using a second sensor with respect to a physical characteristic associated with a patient. Drug delivery system comprises a drug delivery device and an auxiliary device including a processor. Drug delivery device is configured to retain the drug for delivery to the patient and includes sensors configured to collect data on the physiological characteristics of the patient. Processor is configured to receive data from sensors reflecting the collected data and control drug delivery to a patient based on the obtained data in a hierarchy which prioritises data from one of the sensors over the other. According to a third embodiment, a method of administering a drug comprises collecting data using sensors of a drug administration device with respect to a physiological characteristic of a patient; and use of auxiliary device processor, which is a separate device from the drug delivery device for: obtaining data from sensors reflecting the collected data and controlling drug delivery from the device for administering the drug to a patient based on the obtained data, in a hierarchy which prioritises data from one of said sensors over the other.

EFFECT: devices, methods and systems allow adjusting the dosage of a drug based on one or more surrounding circumstances of the patient during drug administration.
