FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A dose inhaler comprises a case body, an aerosol balloon comprising a balloon body, a valve rod and a syringe pressing the valve rod. The valve rod is held in the fixed position inside the case body. The balloon body is installed inside the case and movable if pressed against spring tension. A dose metre comprises at least one indicator element rotatable inside the case body. A control lever is rotatable inside the case body to rotate the indicator element. A control cap comprises at least one rotatable connective element coupled with the control lever. A cap section covers the balloon body from the bottom of the balloon case. The control cap vertically reciprocates by means of elastic spring tension which enables the control lever rotating from a first position into a second position and vice versa, and also enables the indicator element rotating. What is also disclosed is a version of a dosing cap differing by structural embodiment.

EFFECT: decreased pressure tension required for inhalation.
