DESCRIPTION:

BRIEF SUMMARY
FIELD OF THE INVENTION

This invention relates to an inhaling type medicine administering device, for example, suitable to be used for administering granular medicine into lungs under breathing-in action of a patient, and a using method thereof.


BACKGROUND OF THE INVENTION

Methods for administering medicine to the lungs of an asthma patient or the like, include injecting liquid medicine, causing the patient to inhale the medicine by using a liquid aerosol sprayer, allowing the patient to inhale fine granules (having a grain size of, for example, from 5 to 10 .mu.m) filled in a capsule by breaking the capsule, and the like.
Of these medicine administering methods for the asthma patient, the method where the patient inhales the granular medicine filled in the capsule is carried out as follows: The asthma patient holds in his hand an inhaler through which the granular medicine is inhaled; installs the capsule in the inhaler; breaks the capsule with a perforating needle; and inhales the granular medicine through an inhaling opening, or mouthpiece.
However, the inhaler employed in a capsule type device according to a conventional technique is arranged such that only one or two holes are formed in the capsule, and therefore the shape of the hole is not constant, so that there arise problems in which the medicine cannot be sufficiently inhaled.
Additionally, depending on the shape and the area of the hole formed in the capsule, there arise problems in which a large amount of the granular medicine is left in the capsule, thereby causing lack of uniformity in ejection amount (amount of the patient) the medicine.
Further, there are problems in which, for example, the capsule unavoidably drops if the capsule is installed upside down in the inhaler, and it is difficult to take the capsule out of the inhaler after the capsule has been used since the structure of the inhaler is insufficient.


DISCLOSURE OF THE INVENTION

The present invention has been made in view of the above-mentioned problems encountered in the conventional technique and is intended to provide an inhaling type medicine administering device by which the entire amount of granular medicine in a capsule can be effectively administered into the lungs of a patient, and a using method therefor.
An inhaling type medicine administering device of the present invention comprises a medicine administering device main body having an end serving as a capsule accommodating hole and another end serving as an inhaling mouth, an air flow passage formed axially in the medicine administering device main body, a pair of pin insertion holes located on opposite sides of the above-mentioned capsule accommodating hole and formed diametrically in the above-mentioned medicine administering device main body so as to be respectively in communication with an inflow-side and an outflow-side of the air flow passage, and a perforator having pins which are arranged to be inserted through the respective pin insertion holes toward the capsule in order to form holes in the capsule when the capsule is located in the above-mentioned capsule accommodating hole.
Accordingly, first the capsule is positioned within the capsule accommodating hole of the medicine administering device main body, and subsequently the pins of the perforator are inserted respectively into two pin insertion holes. The holes formed in the medicine-filled capsule by the pins of the perforator are arranged to allow the inflow-side of the air flow passage to be in communication with the inside of the capsule through the pin insertion hole, and to allow the inside of the capsule to be in communication with the outflow-side of the air flow passage. Under this condition, when the patient inhales air through the inhaling mouth, air flows from the inflow-side of the air flow passage.fwdarw.the pin insertion hole.fwdarw. the inflow-side hole in the capsule.fwdarw.the inside of the capsule.fwdarw.the outflow-side hole in the capsule.fwdarw.the pin insertion hole.fwdarw.the outflow-side of the air flow passage.fwdarw.the inh
