0B, 10B 'and the throttle passages 24, 24 can be separately flowed. At this time, due to the difference in hole diameter between the throttle passages 24 and the inner pin insertion holes 10B, 10B ', the inner pin insertion holes 10B, 10B' can be preferentially flowed to the inner pin insertion holes 10B, 10B '. In addition, the medicine in the capsule 16 can be reliably transported.

Furthermore, the inhalation-type medication device of this embodiment is the first
While the inhalation-type medication device according to the embodiment of the present invention is intended for patients with low vital capacity, it is intended for patients with high vital capacity, and effectively conveys the drug in the capsule 16 by the amount of air taken in at one time. However, the medicine can be taken efficiently.

In each of the above-mentioned embodiments, the outflow side tapered surface portion 8 is formed on the outer peripheral surface of the other side of the capsule holder 6, and each outflow side passage 13 is formed in the shape of a concave groove that opens to the outflow side tapered surface portion 8. However, the present invention is not limited to this.

That is, in the first modification example corresponding to the first embodiment shown in FIG. 15, the outflow side end surface of the capsule holder 6 is made flat and the outflow side tapered surface portion 8 is eliminated as in the first embodiment. In addition, the outflow side passages 13 ', 13' have a hole shape that extends in the axial direction and communicates with the inner pin insertion holes 11B, 11B '.

Also in the first modified example configured as described above, since the capsule 16 is punched from both the left and right sides, which is a feature of the present invention, a fragment of the capsule 16 generated during perforation is prevented. It can be contained in the capsule 16 and can be prevented from scattering outside.

As described above in detail, according to the present invention of claim 1, the capsule is accommodated in the capsule accommodating hole of the main body of the prescription device, and each pin of the two punching tools positioned on the left and right is capsuled. Insert through the pin insertion holes on the left and right of the accommodation hole, and make holes on both sides of the capsule in the radial direction. In this way, by making holes from both sides in the radial direction of the capsule, broken fragments of the capsule generated at the time of making holes are contained in the capsule and prevented from scattering to the outside. Then, it is possible to prevent the fragment from entering the body of the patient and clogging the inside of each pin insertion hole or the passage on the outflow side, thereby preventing the clogging of the medicine.

When the patient's air is sucked from the suction port in this state, the flow of the suctioned air is changed from the inflow side air passage to the pin insertion hole to the capsule inflow side hole to the inside of the capsule to the capsule outflow side hole. → Pin insertion hole → Vent on the outflow side → Flows to the lungs through the inlet, the patient's mouth, the trachea, etc. Thus, when air enters through the hole on the inflow side of the capsule and is discharged through the hole on the outflow side, it diffuses the drug filled in the capsule, and the drug is mixed in the air to be discharged. The air ejected from the inhalation-type medication device can reliably administer the drug into the lungs of the patient. Further, since all the air that flows in from the inflow side ventilation passage is made to pass through the inside of the capsule, it can be suitably used for patients with low vital capacity.

According to the second aspect of the present invention, by forming a throttle passage that axially connects the inflow side air passage and the outflow side air passage with each other, the flow of the intake air can be reduced. Vent path → Pin insertion hole → Capsule inflow side hole → Inside capsule → Capsule outflow side hole → Pin insertion hole → Outflow side ventilation path → Suction flow and inflow side passage → Throttling passage →
It can be divided into the flow path on the outflow side → the flow that becomes the intake port,
The amount of air introduced into the capsule can be adjusted with or without the throttle passage. That is, it can be preferably used for patients with large vital capacity.

According to a third aspect of the present invention, the drug dispenser main body is provided with a suction piece having one side serving as a holder accommodating portion and the other side serving as a suction port, and a capsule accommodating portion provided inside the holder accommodating portion of the suction piece. By configuring the capsule holder with the accommodation hole formed therein, the air passage can be provided in the capsule holder in the axial direction, and the pin insertion hole can be formed in the suction piece and the capsule holder, respectively. . Further, the suction piece and the capsule holder can be disassembled, and the attached chemicals can be easily cleaned.

According to a fourth aspect of the present invention, the two inflow-side air passages are provided so as to communicate with the pin insertion hole on one side in the axial direction on both sides in the radial direction with the capsule receiving hole interposed therebetween.
Further, since the two vent passages on the outflow side are provided so as to communicate with the pin insertion holes on the other side in the axial direction on both sides in the radial direction with the capsule accommodating hole sandwiched between them, When the inflowing air enters the capsule, it comes to flow through the pin insertion holes located on both sides in the radial direction, and the flow of the air collides in the capsule to generate a turbulent flow. The drug is diffused, and the drug in the capsule is efficiently mixed into the air. As a result, a large amount of a drug can be mixed in the air sucked toward the patient via the vent passage on the outflow side, and the drug can be taken efficiently.

Since the tapered surface portion is integrally formed on the outer peripheral surface on the other side of the capsule holder as in the fifth aspect of the invention, the vent passage on the outflow side is opened toward the tapered surface portion so that the outflow side is opened. The air passage of is formed in the main body of the drug dispenser, and can be gradually opened around the portion protruding from the capsule housing hole toward the inhalation port, and it is possible to prevent the sudden entrainment of the air flow generated near the radial end surface during inhalation, The air flowing from the outflow passage to the suction port can be rectified. And, it is possible to prevent the medicine from adhering to the main body of the medicine dispenser.

According to the sixth aspect of the present invention, the suction piece having one side serving as the holder accommodating portion and the other side serving as the suction port is provided in the holder accommodating portion of the suction piece, and the capsule accommodating hole is opened inside. And a pair of pin insertion holes which are located on both sides in the axial direction of the capsule housing hole of the capsule holder and are formed by penetrating the suction piece and the capsule holder in the radial direction. Of the pin insertion holes, in order to communicate with the pin insertion hole on the one side in the axial direction, the inflow side passage formed in the capsule holder radially outside the capsule accommodating hole and the pin insertion hole. In order to communicate with the pin insertion hole on the other side in the axial direction, the outflow side passage formed in the capsule holder radially outward of the capsule receiving hole and the capsule for medicine are stored in the capsule receiving hole. In order to make holes from both the left and right sides of the capsule in the radial direction in the above state, it is composed of two left and right hole punching tools having a pair of pins that are inserted from the pin insertion holes toward the capsule. Thus, the inflow side passage and the inside of the capsule and the inside of the capsule and the outflow side passage can be communicated with each other through the pin insertion hole.

When the patient inhales air from the inhalation port in this state, the flow of air is as follows: each inflow side passage → inlet side pin insertion hole → capsule inflow side hole → inside the capsule → capsule outflow side hole. → Outlet side pin insertion hole → Outflow side passage → Flows to the lungs through the inhalation port, patient's mouth, trachea, etc. At this time, when air enters through the hole on the inflow side of the capsule and discharges from the hole on the outflow side, the medicine filled in the capsule is diffused by the flow of the air, and the medicine is released from the suction port. Can be mixed in air and transported,
The drug in the capsule can be effectively administered into the lungs of the patient, and the drug can be taken efficiently.

Further, since the holes are made from the both sides of the capsule by the two hole punches, the broken fragments generated at this time can be accommodated in the capsule, and the broken fragments are inserted into the pin insertion holes on the outflow side. Further, it is possible to prevent clogging of the outflow passage or the like and reliably prevent clogging of the medicine, and to further improve the medicine taking efficiency.
