DRUG HEAT CYCLE LIMITER FOR INJECTION DEVICE Russian patent published in 2012 - IPC A61F9/00 A61M31/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. An injection unit comprising a dosing cavity body, a temperature control unit, a thermal sensor, a key and a controller, the dosing cavity body has an internal cavity and an external cavity. The internal cavity partially limits a dosing cavity for receiving an amount of a substance; the temperature control unit at least partially encloses the dosing cavity body and adjusts substance temperature in the dosing cavity. The thermal sensor adjoins the temperature control unit and reads out the temperature of the area surrounding the temperature control unit. The key is coupled with the temperature control unit. The controller regulates the temperature control unit and the key so that first non-zero voltage is supplied to the temperature control unit while the temperature control unit before the preset temperature is developed, and thereafter second non-zero voltage is supplied to maintain the required temperature of the temperature control unit.

EFFECT: group of the inventions extends the range of equipment, namely the dosing and injection units allowing controlling rate and temperature of the injected volume.
