Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a mouthpiece for a medicinal liquid sprayer.

BACKGROUND TECHNOLOGY AND THEIR PROBLEMS Conventionally, various pocket-sized and conveniently portable medicated liquid spray devices have been proposed for the purpose of treating unexpected attacks of asthma patients. When treating an asthma attack, it is extremely difficult for patients who are having difficulty breathing to directly inhale the medicinal solution sprayed from a nebulizer. This problem can be solved to some extent by using a wrap-shaped mouthpiece, such as those used during treatment at hospitals, but the wrap-shaped mouthpiece is bulky and inconvenient to carry. This would make it more convenient to carry, but it would be time-consuming to assemble, making it less urgent for seizure treatment, so each has its pros and cons.

The present invention was made with the aim of eliminating such conventional problems.

Means for Solving the Problems The present invention is capable of being assembled and folded, and has a rectangular cylindrical shape when assembled and a flat shape when folded. A mouthpiece is formed with a curved mouth edge that can be tightly attached, and the other mouth is provided with a lid that can follow the assembly and folding operations of the main body and has an insertion opening for a medicinal liquid injection nozzle in the center. A medicinal liquid sprayer comprising: an inlet port formed in the main body; and a valve leaf that closes when the main body is pressurized and opens when the main body pressure is reduced. Pertains to utility bills.

Embodiment An embodiment of the present invention will be described below based on the accompanying drawings.

The mouthpiece main body 1 has a diamond-shaped cylindrical shape and is composed of a pair of left and right upper face plates 1a, 1a and lower face plates 1b, 1b, and is normally folded flat as shown in FIG. In this folded state, the upper and lower folds 3, 3 are closed, and the middle folds 2, 2 are closed.
is open.

In the state shown in Fig. 3, when the upper and lower folds 3, 3 in the closed state are pressed in the direction toward each other, the upper and lower folds 3, 3 open from 0° to approximately 90°. At the same time, the intermediate fold parts 2, 2 are 180°
The tube is closed at an angle of about 90 degrees from the center, resulting in a diamond-shaped cylindrical assembled state as shown in FIGS. 1 and 2.

A mouthpiece portion 4 having a curved, for example, arc-shaped mouth edge is formed at one side of the mouth portion of the mouthpiece main body 1 . The mouthpiece 4 only needs to have a structure that allows it to fit well against the patient's mouth.

At the other end of the mouthpiece body 1, there is a lid body 5 which is automatically folded and assembled in accordance with the folding and assembly operations of the mouthpiece body 1, and which has an insertion opening 6 for a drug liquid injection nozzle in its center. Be prepared.

For example, as is clear from the developed view in FIG. 4 and the diagram showing the state in the middle of assembly in FIG. flaps 51, 52 and 53, 5
4, and the adhesive portion 5 of the pair of flaps 51 and 52.
By pasting together the adhesive portions 53a, 54a of the flaps 1a, 52a and the flaps 53, 54, such an automatically assembled lid 5 can be constructed. Lid body 5
Arc-shaped cuts 61 to 64 are formed in each flap 51 to 54 so that when the flap is assembled, an insertion opening 6 is formed in the center thereof.

The mouthpiece of the present invention usually maintains a flat folded state as shown in FIG. 3, and can be carried in a small bulky state. In this case, when the main body 1 has an equilateral quadrilateral shape as shown in the figure, two more folds can be folded according to the intermediate folds 2, 2 compared to the state shown in FIG. 3, making it more convenient to carry in a smaller volume.

On the other hand, when in use, as shown in FIG.
3 are pressed in the direction toward each other, the main body 1 is assembled into a diamond-shaped cylinder shape by one-touch operation by this pressing, and the lid body 5 is also automatically assembled following the assembly operation of the main body 1. In this assembled state, as shown in FIG.
By pressing the mouthpiece against the mouthpiece C, inserting the spray nozzle _A1 of the sprayer A through the insertion opening 6 in the center of the lid body 5, and performing a spraying operation, the sprayed medicinal solution can be sucked through the mouthpiece.

After the suction operation, the injection nozzle _A1 of the sprayer A is removed from the insertion port 6 and then folded back into the state shown in FIG. 3 to prepare for the next operation.

At the time of suctioning the sprayed medical solution, the pressure inside the mouthpiece main body 1 is temporarily reduced. The occurrence of such a reduced pressure state is undesirable for smooth suction. In the present invention, for the purpose of preventing the occurrence of a reduced pressure state during suction, an intake port 7 is provided at an appropriate location of the main body 1, for example, on the top plate 1a. A valve leaflet 8 with, for example, a cross cut 8a is provided, which automatically opens due to the pressure difference between the inside and outside when the pressure is reduced. According to this configuration, when the pressure inside the main body 1 is reduced due to suction of the sprayed chemical liquid, the valve membrane 8 opens at the cut 8a and outside air is sucked in through the intake port 7, so that the sprayed chemical liquid can be easily sucked. When the chemical solution is injected from the injection nozzle, the inside of the main body 1 is temporarily pressurized, but since the valve membrane 8 is closed during pressurization, the sprayed chemical solution flows out of the main body 1 from the intake port 7. There is no danger of that.

9 and 10 show still another embodiment of the present invention, in which each face plate 1a, 1a, 1
An auxiliary fold part 9 is formed at a position between the intermediate fold part 2 and the upper and lower fold parts 3 in parallel to the fold parts 2 and 3 at b and 1b.
Although the auxiliary fold portion 9 is shown in the figure as ending halfway in the length direction, it may be formed over the entire length in the length direction.

If such an auxiliary fold 9 is formed, each face plate 1a, 1a, 1b, 1b will be slightly bent at the auxiliary fold 9 to form an arc shape when assembled and used, and the whole will become circular. As it approaches, mouthpiece part 4
The contact with the mouth C (see Figure 6) becomes softer.

Furthermore, in this embodiment, the upper end portion of the mouthpiece portion 4 is indented around the upper fold portion 2 . The formation of such an indented part 10 makes the contact of the mouthpiece part 4 against the lower part of the nose C ₁ (see FIG. 6) softer.

Therefore, by forming the auxiliary fold portions 9 and the indented portions 10, the usability during assembly and use can be improved.

Effects As described above, the mouthpiece of the present invention usually has a flat folded state, making it convenient to carry, and can be assembled with one hand and a single touch when in use. This can be done easily and smoothly while inhaling outside air through the mouth.
It is fully capable of responding to emergencies during seizure treatment, and is extremely useful as a mouthpiece for a pocket-type oral drug sprayer.
