Abstract

PROBLEM TO BE SOLVED: To enable most of a medicinal liquid to be ejected from a drug inhaler to reach a diseased part to be medically treated in accordance with the natural respiration of a user. SOLUTION: The injection nozzle B of a drug inhaler A is attached to one of the tapered end parts of a contained main body 10 consisting of a first part 12 and a second part 14, each of which has a conical bellows with a tapered end part, structured in monolithic form. In addition, a mouthpiece is attached, in freely detachable manner, to the other tapered end part 24 of the container main body 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable adapter for a pharmaceutical inhaler, and more particularly to a portable adapter for attaching a medical liquid in the form of a spray to a pharmaceutical inhaler for oral administration.

[0002]

2. Description of the Related Art Conventionally, a liquid therapeutic drug for asthma, for example, a liquid drug such as a bronchodilator is provided by atomizing with an aerosol, and a simple nozzle device is used as a pharmaceutical inhaler.

[0003]

It is preferable that this type of liquid medicine mix well with the air sucked by the patient's breath and reach the affected area with the patient's natural breathing in order to improve the therapeutic effect. However, when the drug solution is sprayed directly into the mouth by the drug inhaler, most of the drug solution is applied to the inner wall of the oral cavity and pharynx before the atomized drug solution reaches the affected area such as the bronchus to be applied. In addition, since it is administered without relying on the patient's natural breathing, it is inconvenient for the effect of the drug.

In view of the above-mentioned problems, the main object of the present invention is to deliver most of the medicinal solution ejected from the medicinal inhaler to the affected area to be treated according to the natural respiration of the user. (EN) Provided is a portable adapter for a medical inhaler.

A further object of the present invention is to provide a portable adapter for a medical inhaler which has a reduced size when not in use and is convenient to carry.

[0006]

In order to achieve this object, the portable adapter of the pharmaceutical inhaler of the present invention comprises a first part formed into a conical bellows having two tapered ends. A structure in which the injection port of the pharmaceutical inhaler is attached to one tapered end of the container body formed integrally with the second part, and the mouthpiece can be attached to and detached from the other end of the body I am doing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a portable adapter for a medical inhaler of the present invention is a device to be used by being attached to a medical inhaler A, which is a cone having a tapered end so that it can be folded with a soft synthetic resin. It is composed of a container body 10 in which a first portion 12 and a second portion 14 formed in a bellows shape are integrally formed by a central cylindrical portion 16 having the largest diameter, and the first portion 12 has the smallest diameter. An opening 2 into which the chemical solution ejection portion B of the inhaler A can be inserted into the end portion 18
A first disc 22 having a zero is attached.

At the smallest diameter end 24 of the second portion 14, there is a second disc 28 to which a mouthpiece 26 for inhalation can be removably attached, for example by screwing or other suitable means. It is attached.

As shown in FIG. 2, the mouthpiece 26 for inhalation is a hollow cylindrical body composed of an inhaling portion 30 and an end portion 32 attached to the second disc 28, and a valve is provided inside the end portion 32. A device is provided.

The valve device has a valve plate 34 capable of almost closing the opening of the end 32, and the valve plate 34 is a mouthpiece 2.
6, a valve seat ring 36 fitted and fixed in the opening of the end 32 for holding the container body 10 so as not to escape from the container body 10, and a valve plate 34 inside the mouthpiece 26.
And a stopper 38 provided on the inner wall of the mouthpiece 26 in order to restrict the movement of the mouse.

[0011]

The portable adapter of the pharmaceutical inhaler of the present invention is constructed as described above in detail, and therefore, when the pharmaceutical solution of the pharmaceutical inhaler A in which the medicine is enclosed is sucked using this adapter. In FIG. 1, the conical first portion 12 and the second portion 14, which are formed into a bellows, are pulled in the longitudinal direction from the folded state as shown in FIG. 3 and expanded as shown in FIG. , The drug solution ejecting portion B of the medicine inhaler A enclosing the medicine is fitted into the opening 20 of the disc 22 fixed to the end opening 18 of the first portion 12, and the end portion 3 of the mouthpiece 26.
0 is attached to the end opening 24 of the second portion 14.

Therefore, the liquid medicine of the medicine inhaler A is supplied to the container body 1.
When jetted into 0, the rapidly sprayed fine particles of the drug solution are diffused in the central portion of the container body 10, lose their speed, and are completely dispersed and mixed in the air in the container body 10.

When the user sucks from the mouthpiece 26, the drug solution which is completely dispersed and mixed in the air in the container body 10 is sent to the trachea from the oral cavity together with the air as the user sucks, so that The amount attached to the inner wall such as the pharynx is extremely reduced, and most of it reaches the required affected part, so that the drug effect can be sufficiently achieved.

Further, even when the suction is temporarily stopped during use, the valve plate 34 in the mouthpiece 26 closes the opening, so that the chemical liquid mixed with the air in the container body 10 is discharged to the outside. There is no risk of leakage.

When the portable adapter of the pharmaceutical inhaler of the present invention is not used, the mouthpiece 26 is removed and the first portion 12 and the second portion 14 which are formed into a conical bellows are folded. As shown in FIG. 3, the bellows-shaped first and second portions 12 and 14 are housed in the cylindrical portion 16 having the largest central diameter. Therefore, it is extremely compact and convenient to carry at all times.
