Inhaler aid with reed for minute powdery curative medicine

摘要

The present invention provides an inhaler aid which maximizes utility of an inhaler for the minute powdery curative medicine, and which is used by being attached to the inhaler so that people including a user can objectively ascertain in each case whether an inhalation operation has been correctly performed. In the present invention, the inhaler aid with the reed for the minute powdery curative medicine has a configuration characterized in that the reed is fitted into a right side of a main unit made of silicon rubber, and the inhaler aid is attached to a mouthpiece portion of a conventionally used inhaler for the minute powdery curative medicine such that the aid equipped with the reed is placed between the inhaler for the minute powdery curative medicine and a mouth of a patient, and when an intake operation has been correctly performed, a sound is produced.

主权项

1. An inhaler aid to be fitted to a mouthpiece of an inhaler for inhaling minute powdery curative medicine, said inhaler aid, comprising:
a main unit having a silicon rubber tube used to aid the inhaler for minute powdery curative medicine, and a horn-shaped junction at a lower portion of the main unit, an engagement portion which is provided at an upper portion of the main unit, the engagement portion including left and right projections, each having a holding member at an end thereof; and a reed fitted into a side of the main unit; wherein when the inhaler aid is joined to a mouthpiece of the inhaler for the minute powdery curative medicine, a sound is produced from the reed only when an inhalation has been correctly performed, wherein the horn-shaped junction includes a front joint piece and a rear joint piece, the front joint piece and the rear joint piece projecting further away from the engagement portion than left and right lateral ends of the horn-shaped junction, wherein, when viewed from a direction where the left and right projections of the engagement portion overlap, the horn-shaped junction has an arched shape such that the front joint piece and the rear joint piece of the horn-shaped junction correspond to bases of the arched shape and the left and right lateral ends of the horn-shaped junction correspond to a top of the arched shape, wherein an inhalation flow path in said main unit is defined by a junction inner peripheral portion and an inner peripheral surface, the junction inner peripheral portion corresponding to inner surfaces of said front joint piece, said rear joint piece, said left lateral end and said right lateral end, wherein said junction inner peripheral portion tapers in a left-right direction and in a front-rear direction towards said inner peripheral surface, wherein said inhaler is selected from the group consisting of:
(a) a disk-shaped inhaler having a mouthpiece shaped to fit the curved shape of the junction inner peripheral portion,(b) an inhaler having longitudinally elongated air grooves and a mouthpiece with a cylindrical tapered portion, a lower portion of said inner peripheral surface being fittable with a lower portion of said mouthpiece, and(c) an inhaler having a mouthpiece with holes formed on the left and right sides thereof, a diameter of said inner peripheral surface corresponding to a diameter of upper ends of said holes formed of the left and right sides of the mouthpiece, wherein said inhaler aid is fittable to any one of inhalers (a), (b) or (c) while permitting inhalation of said minute powdery curative medicine and producing sound from said reed only when an inhalation has been correctly performed, and wherein said inhaler aid is fittable to inhaler (a) such that an entirety of a surface of said junction inner peripheral portion contacts an entirety of a surface of said mouthpiece of said disk-shaped inhaler.
