Each medicine accommodating section accommodates therein medicine in powder form. A section defining an inflow hole is formed at the inner peripheral side of the medicine accommodating body to supply air into the medicine accommodating section. A section defining an outflow hole is formed at the outer peripheral side of the medicine accommodating body to flow out the medicine introduced by air.

Inhaling type medicine administering apparatus and medicine cartridge used therein

A blister pack for a inhalant medicator has a plurality of medical powder storage chambers spaced apart from each other in a circumferential direction. The inhalant medicator includes a pricking tool with a pair of parallel pins that prick inflow and outflow holes in one of the medical powder storage chambers during a preliminary operation of inhalant medication. The inflow and outflow holes are spaced apart from each other by a predetermined distance in a direction parallel to a lid panel of the blister pack to produce turbulent airflow within the medical powder storage chamber during inhalation during which the medical powder is inhaled by a patient's breathing. The medical powder storage chambers are dimensioned and designed to properly regulate or control properties of the airflow passing through the medical storage chamber, to ensure the airflow is suitable for the medical powder storage chamber.

Inhalant medicator

An inhalator including an inhalator body including a powder receiving chamber for receiving a powder, an air-powder mixture reservoir for temporarily storing an air-powder mixture flowing from the powder receiving chamber, and a diluent air passage for introducing a diluent air into the air-powder mixture reservoir. The air-powder mixture is formed within the powder receiving chamber when an air is introduced into the powder receiving chamber. The air-powder mixture within the air-powder mixture reservoir is admixed with a diluent air introduced thereinto through the diluent air passage. The diluted air-powder mixture is discharged from an air-powder mixture outlet into a user's oral or nasal cavity. A powder composition for inhalators includes at least two kinds of fine particles different in particle diameter.

Inhalator for administering powder composition

A diffusion chamber block is provided in a block mounting hole A of an inhalant port , and a granular medicine diffusion chamber is formed in the diffusion chamber block . The granular medicine diffusion chamber is formed at a side of the inhalant port with a granular medicine inflow opening A and at a side of a capsule housing hole with a granular medicine outflow opening B. A diffusion chamber in flow passage is provided to communicate an outflow air passageway with the granular medicine inflow opening A, whereas a diffusion chamber outflow passage is provided to communicate the granular medicine outflow opening B with the inhalant port . When inhaling granular medicines in the capsule housing hole via the inhalant port by way of breathing action, there results in counter-flow vortex within the granular medicine diffusion chamber . The counter-flow cortex acts to finely break and atomize massive granular medicines, thus promoting atomization of the granular medicines.

Inhalation type drug dispenser

An inhalant medicator includes a medicator body which is formed therein with a cylindrical fit hole , an inhalant port , an inflow air passageway , and an outflow air passageway , and a medical powder storage cylindrical member which is installed or fitted into the cylindrical fit hole in a manner so as to open or close the air passageways and with respect to a medical powder storage chamber . The inhalant medicator is constructed by two component parts, namely the medicator body and the medical powder storage cylindrical member , thus ensuring simplified structure and reduced production costs. Additionally, powder-and-granular medicine or medical powder is tightly encapsulated within the medical powder storage chamber by means of the medical powder storage cylindrical member , thus preventing loss of flow of the medical powder

An inhalant medicator comprises a medicator body formed at one axial end with a capsule housing hole and at another axial end with an inhalant port, an inflow air passageway having an axial inflow passage extending in an axial direction of the medicator body and a first pin insertion hole extending in a radial direction of the medicator body for communicating the capsule housing hole with the atmosphere, an outflow air passageway having an outflow passage extending in the axial direction of the medicator body and a second pin insertion hole extending in the radial direction of the medicator body for communicating the capsule housing hole with the inhalant port, and a boring tool having pins insertable toward a capsule through the first and second insertion holes for pricking holes in the capsule accommodated in the capsule housing hole with the pins.

A medicine administering apparatus, suitable for administering granular medicine to a patient, comprises a main body which has a medicine passage and a medicine accommodating chamber. The apparatus further includes a location changing member formed with a medicine loading chamber. The location of the medicine loading chamber is changed between a first position, where the medicine loading chamber is separate from the medicine passage, and a second position, where the medicine loading chamber is in the medicine passage. Movement of the location changing member changes the position of the medicine loading chamber. A medicine loading member compresses a predetermined amount of the medicine into the medicine loading chamber at the first position, the predetermined amount corresponding to one dose. Medicine within the medicine loading chamber may be inhaled through the medicine passage by a patient when the patient breathes in.
