However, this drug dispenser only involves pre-filling the nasal drops in a metered dose syringe in a dissolved state, and by pressing the plunger, the nasal drops can be subdivided and sprayed.
Therefore, Patent Document 1 does not disclose a system for dissolving medicines in a solid state stored in capsules.

Embodiment Construction

[0033] (dissolve system when used)

[0034] Hereinafter, an in-use dissolving system according to an embodiment of the present invention will be described with reference to the drawings.

[0035] exist figure 1 The dissolving system 1 at the time of use that can dissolve a predetermined substance stored in a capsule in a dissolving liquid according to one embodiment of the present invention is shown in . The in-use dissolving system 1 is combined with the ejector 2 for ejecting the solution produced by the in-use dissolving system 1, thereby constituting the in-use dissolving system 5 (ie, in-use dissolving ejection system).

[0036] In use, the dissolving system 1 includes: a capsule holder 3 having a hollow inner space formed in a cylindrical shape; and a solution holder 4 having a hollow inner space formed in a cylindrical shape. The capsule holder 3 accommodates a capsule 6 in which a predetermined substance such as drug powder is wrapped with PTP or the like, and the di...

Abstract

Provided is a time-of-use dissolving system for dissolving a predetermined substance in a capsule using a dissolving liquid at the time of use. The time-of-use dissolving system 1 is provided with a capsule holder 3 and a dissolving liquid holder 4. The capsule holder 3 is provided with a first opening portion and a first needle portion, and forms a capsule storage compartment in which a capsule 6can be stored. The dissolving liquid holder 4 is provided with a closed end portion, a second opening portion, and a second needle portion which is slidable in an internal space and includes a dissolving liquid passageway, the dissolving liquid holder 4 forming a dissolving liquid compartment. The capsule holder 3 and the dissolving liquid holder 4 are slidably mated with each other in a state inwhich needle tips of the first and the second needle portions are opposed to each other, with the capsule 6 disposed between the needle tips. A sprayer 2 provided with a twice-extrusion mechanism ismated with the capsule holder 3. The mechanism is provided with a lever parallel with a piston rod, a spring between a lower-end plate and the piston rod, and a boss, wherein the lever is provided with a stopper that is locked on a spout by the first extrusion, a lever lower portion engageable with the boss, a lever return, and a recess portion.

Description

technical field [0001] The present invention relates to a dissolving system for dissolving a prescribed substance in a dissolving liquid at the time of use. Background technique [0002] It is known that pharmaceuticals often become unstable due to hydrolysis in a solution state. Therefore, in areas where the storage conditions of the medicines are not perfect and the temperature is high, it is preferable to store the medicines in a solid state in terms of the stability of the medicines. In addition, it is considered that the stability can be further improved by enclosing the medicine in a solid state (or in a fluid state without moisture) in a capsule packaged with PTP or the like. Therefore, it is desired to develop a system for dissolving a drug in a solid state stored in a capsule. [0003] As a system for ejecting medicines, a quantitative syringe type ejector described in Patent Document 1 is known. However, this drug dispenser only relates to a technique in which n...
