  By the way, the nasal spray ejector mentioned above and the medicines administered to the nasal cavity by the patient's own operation are generally liquids. It was difficult to keep, and sometimes the medicine flowed out of the nose before it was fully effective. On the other hand, it was also studied to keep the powder on the inner surface of the nasal cavity for a long time by attaching the powder to the inner surface of the nasal cavity using a powdery substance as a drug. There is a possibility that this mass may directly enter the nasal cavity by suction, and there is still room for improvement.

  The problem of the present invention is that it is possible to reliably exert the expected effect by sucking the powder, and even if the powder becomes a lump, the possibility of sucking this lump reliably is eliminated. A new suction-type dispenser that can be applied and does not burden the patient is proposed.

The present invention includes a base having a storage chamber for storing an inner container body filled with medicinal powder, a lid having a perforated portion for opening a hole in the inner container body arranged in the storage chamber, and covering the base; A suction-type prescription device comprising a cylindrical nozzle that is integrally connected to the lid and capable of sucking the powder of the inner container body through a tip opening provided at the tip,
The lid body has an air introduction hole that guides outside air into the lid body with suction,
The perforated part is provided at the tip of a cylindrical body that is integrally connected to the lid and is coaxial with the nozzle and extends toward the storage chamber,
Forming a straight outlet passage connected to the tip opening inside the cylinder and the nozzle,
While providing a mesh member having a plurality of fine holes in the outlet passage ,
The suction type dispenser is characterized in that the storage chamber is open at the bottom, and the inner container body is pushed up from below to be removable from the storage chamber .

  A plurality of ribs extending along the axis of the cylinder are provided on the outer surface of the cylinder, and the rib has an outer passage for introducing air in the lid into the inner container body therebetween. It is desirable.

  It is desirable to provide a spiral member in the outlet passage that swirls the air in the outlet passage with suction.

  The inner container body is preferably a blister pack.

  A base for storing the inner container body filled with the medicinal powder and a lid body having a perforated portion for opening a hole in the inner container body and covering the base, and sucking the medicinal powder from the tip opening of the nozzle connected to the lid body Regarding the suction-type prescription device, the lid body is formed with an air introduction hole that guides outside air into the lid body as a result of suction, and a perforated portion is provided at the tip of the cylinder body that is integrally connected to the lid body. Since an exit passage connected to the tip opening through the inside of the nozzle is formed, and a mesh member having a plurality of fine holes is provided in the exit passage, the powdery powder is sucked through the mesh member, The lump powder is effectively blocked by the mesh member and effectively prevented from entering the nasal cavity. In addition, though a hole in the inner container body may cause the broken portion of the inner container body to separate and become broken fragments, like the bulky drug powder, the broken fragments can surely enter the nasal cavity. Can be prevented.

  When providing a plurality of ribs extending along the axis on the outer surface of the cylinder and providing an outer passage between these ribs for introducing the air in the lid into the inner container body, the inner container body Even when the rupture part of the tube is in close contact with the rib on the outer surface of the cylindrical body, air can be sent into the inner container body through the outer passage, so that the inner container body does not become negative pressure during suction and places a burden on the patient. It can be sucked without.

  When a spiral member that swirls the air in the outlet passage as it is sucked is provided in the outlet passage, the medicine powder sucked into the nasal cavity can be uniformly diffused, and the expected effect of the medicine powder is ensured. Can be demonstrated.

  When a blister pack is used as the inner container body, the inner container body is kept airtight until just before use, so that the possibility of the powder becoming agglomerated can be reduced as much as possible.
