Benefits of technology

[0007] Accordingly, it is an object of the invention to provide an inhalant medicator, which avoids the aforementioned disadvantages.
[0009] It is a still further object of the invention to provide a blister pack suitable for an inhalant medicator, which enhances a medication efficiency, effectively diffusing medical powder stored in a medical powder storage chamber of the blister pack depending on characteristics or properties of the medical powder, such as a strong condensation property, and a particle size.

Problems solved by technology

Thus, some medical powder may be undesirably left in the medical powder storage chamber after prescribing the medical powder toward within lungs of a patient by breathing action.
As a result of this, the patient cannot inhale a specified amount of medical powder into the lungs, thus lowering medical benefits of powdered or granular medicines.

first embodiment

[0053] The inhalant medicator of the first embodiment is constructed as previously discussed. Hereinbelow described in detail in reference to FIGS. 9-11 are the preliminary operation of inhalant medication through which a patient inhales medical powder, and the flow of air and the flow of medical powder during inhalation.

[0054] First of all, blister pack holder 8 is removed from the holder mounting groove 6 of medicator body 2. During removal of the holder 8, the guide groove 8E, formed in the underside of the holder and radially outwardly extending from the center of the holder, must be axially aligned with respect to the axis of the medicator body 2 under a condition in which the outermost end of guide groove 8E faces the inhalant port 7. Then, the holder 8 can be removed from the medicator body 2 by pulling the holder 8 against the bias produced by the two spring-loaded balls 9B of the positioning mechanism 9. Then, blister pack 16 is fitted to and installed on the upside of hold...

second embodiment

[0060] As discussed above, according to the inhalant medicator of the second embodiment, the flow-constriction orifice passage 26 is defined within the medical powder storage chamber 25 of blister pack 21 by the flow-constriction portion 23C of blistered portion 23 so that the flow-constriction orifice passage 26 is located between the inflow holes (H1, H1) and the outflow holes (H2, H2). The flow-constriction orifice passage 26 acts to properly regulate or control the air flow passing through the medical powder storage chamber 25 depending on the properties or characteristics peculiar to medical powder stored in the storage chamber 25. Therefore, it is possible to produce turbulent air flow suitable for medical powder stored in the storage chamber 25 by properly determining or setting an orifice size of the flow-constriction orifice passage 26 in due consideration of characteristics or properties of the medical powder, such as a particle size (fine powder or granule), a condensatio...

Abstract

A blister pack for an 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 stored in the storage chamber.

Description

TECHNICAL FIELD [0001] The present invention relates to an inhalant medicator suitable to prescribe granular or powdered medicines toward within lungs of a patient by way of breathing action of the patient, and particularly to a blister pack suitable for the inhalant medicator. BACKGROUND ART [0002] Generally, there are two medications of prescribing medical powder toward within lungs of an asthmatic patient, that is, one being a medication that a medicine is inhaled by way of a liquid aerosol atomizer, and the other being an inhalation treatment by way of which granular or powdered medicines (which will be hereinafter referred to as “medical powder”) encapsulated in a capsule or stored in a medical powder storage chamber are inhaled. [0003] Of these medications for an asthmatic patient, an inhalant medicator used for an inhalation treatment where a dose of medical powder is inhaled, is generally constructed by a medicator body including a capsule housing chamber (or a medical powde...
