INJECTION APPARATUS Russian patent published in 2017 - IPC A61M5/315 

FIELD: medicine.

SUBSTANCE: injection apparatus comprises a housing where a receptacle for a reservoir with injected liquid is provided. At that, the injection apparatus has a control for injection dose setting. The injection apparatus has a dosing mechanism that is rotatable relative to the body about the central longitudinal axis of the injection apparatus when the injection dose is set. The dosing mechanism has a zero position and at least one injection position. Moreover, no dose value is set in the zero position, and the prescribed dose of injected liquid is set in each injection position. Moreover, the injection apparatus has a fixing device that operates between the delivery part and the housing. The delivery part is rotatable about the central longitudinal axis of the injection device to set the injection dose, whereby during setting of the injection dose, the delivery part is connected without the possibility of relative rotation with the dosing mechanism. In this case, when the dose is squeezed out, it is possible to move the delivery part relative to the housing towards the central longitudinal axis and to direct it to at least one longitudinal edge of the housing. Moreover, at least one fixing element of the fixing device is formed on the longitudinal edge. In this case, each injection position of the dosing mechanism corresponds to the position of fixation of the fixing device. In this case, the metering mechanism is designed to be installed in at least one intermediate position in which no prescribed dose of the injected liquid is set, with a spring provided between the metering mechanism and the housing, which is arranged to return the dosing mechanism from the intermediate position to the injection position, or in the zero position in the absence of influence on the control.

EFFECT: improved application convenience.
