DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a medicine administering device suitable for administering powder-state medicine filled in a medicine accommodating chamber, to nasal cavities, and a method of using the same.
BACKGROUND TECHNIQUE
In general, a method of curing by administering powder-state medicine through nasal cavities has been employed for a patient of nasal allergy, asthma and the like. In this curing method, the powder-state medicine filled in a medicine accommodating chamber, such as a capsule or the like, is administered into nasal cavities by using an exclusive medicine administering device for nasal cavities.
One sprayer to be used for this curing method is shown in Japanese Patent Provisional Publication No. 59-34267.
In the sprayer according to this conventional technique, a cylindrical member is provided at its air inflow-side with a pump section and is formed at its air outflow-side with a concave-shaped section into which a capsule is to be inserted. The cylindrical member is detachably provided at its tip end side with a tip end section, which is formed with an opening section which serves as a medicine spray hole. The tip end section is fitted to the cylindrical member to form a capsule accommodating section. Further, a cap is provided to be detachably fitted to the above-mentioned cylindrical member and the tip end section, and the cap is provided thereinside with an axially extending needle. The cap is fitted to the above-mentioned cylindrical member, thereby forming a hole in the capsule accommodated in the capsule accommodating section with the needle inside the cap.
In this conventional technique, first, the capsule filled with powder-like medicine is inserted in the concave-shaped section of the cylindrical member. Thereafter, the tip end section is fitted to the cylindrical member, thereby accommodating the capsule in the capsule accommodating section. Then, the cap is installed through the tip end section in such a manner that the needle disposed inside the cap pierces the opening section of the tip end section, thereby forming holes at the axially opposite sides of the capsule.
Next, when the medicine is administered, the tip end section is inserted into one of the nasal cavities of the patient, after detaching the cap from the cylindrical member. Then, the pump section is pressed so that air from the pump section streams through an air introduction passage into the capsule. Accordingly, the medicine in the capsule is sprayed through the opening section into the nasal cavities of the patient under the action of this air. Insertion of the tip end section into the nasal cavity is made alternately to both nasal cavities and the pressing action of the pump section is repeated, thereby accomplishing medicine administration to the patient.
Additionally, a clearance is formed between the capsule accommodating section and the capsule so that the medicine administration to nasal cavities is made alternately to the left and right nasal cavities so as to prevent all the medicine in the capsule from being administered after only one pressing action of the pump section. A predetermined amount of the medicine is administered after about four pressing actions of the pump section for each nasal cavity.
Now, in the sprayer according to the above-discussed conventional technique, medicine administration alternates between the left and right nasal cavities, and therefore pressing the pump section and inserting the cylindrical member into each nasal cavity must be repeated many times in order to supply the left and right nasal cavities with an equal amount of the medicine. Accordingly, there is a problem in that treatment during medicine administration becomes cumbersome.
Furthermore, when the hole is formed in the capsule in order to make preparation of the medicine administration, the tip end section is detached from the cylindrical member, and then the capsule is accommodated. Next, the cap is fitted around the above-mentioned cylindrical member and the tip end section, t
