[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nasal drug dispenser suitable for use in the nasal administration of powdered medicines filled in capsules.

[0002]

2. Description of the Related Art Generally, a method for treating a patient with nasal allergy, asthma or the like by administering a powdered drug through the nasal cavity is adopted. Further, in this treatment method, a powdery medicine filled in a capsule is administered into the nasal cavity by using a dedicated sprayer.

[0003] Further, as a nebulizer used for this treatment, there is known a nebulizer disclosed in JP-A-59-34267 (hereinafter referred to as "prior art").

In the atomizer according to this prior art, a pump portion is provided on the air inflow side of the cylindrical member, a concave portion into which a capsule is inserted is formed on the air outflow side of the cylindrical member, and the tip end side of the cylindrical member is formed. A detachable tip end portion having an opening serving as a chemical spray port is detachably provided, and a capsule accommodating portion is formed inside by fitting the tip end portion to the cylindrical member. Furthermore, a cap is provided which is detachably fitted to the cylindrical member over the distal end portion, a needle extending in the axial direction is provided in the cap, and the cap is mounted with the distal end portion fitted to the cylindrical member. Thus, the capsule contained in the capsule containing portion is pierced by the needle in the cap.

According to the prior art thus constructed, when the capsule is to be pierced in preparation for drug administration, the capsule filled with the drug in powder form is first inserted into the concave portion of the cylindrical member and then the distal end portion of the cylindrical member is inserted. By accommodating the capsule into the capsule accommodating portion, and attaching the cap from the distal end so that the needle is inserted into the opening of the distal end.
A needle is provided in the cap to make holes on both axial sides of the capsule.

Next, at the time of administering a drug, the cap is removed from the cylindrical member, the tip is inserted into one of the nostrils of the patient, and the pump is pressed to allow air from the pump to pass through the air introduction passage. The drug in the capsule is circulated in the capsule, and the air causes the drug in the capsule to be sprayed into the nasal cavity of the patient from the opening, and the insertion into the nasal cavity is exchanged alternately and the pressing operation of the pump section is repeated, thereby giving the drug to the patient. Is to be administered.

Further, since the nasal cavity is alternately dosed to the left and right nasal cavities, the medicine in the capsule is not completely administered by one pressing operation of the pump section, so that the medicine is not injected between the capsule accommodation section and the capsule. A space is provided in the pump, and the prescribed amount of the drug is administered by performing the pressing operation of the pump part about four times in one nasal cavity.

Next, the medication operation for spraying the drug in the perforated capsule K into the nasal cavity of the patient will be described.

First, each spray nozzle 16 is inserted into both nasal cavities of the patient, and as shown in FIG.
By crushing C, an air flow is generated from the pump unit 13, this air is made to act on the air supply passage 5, and the supply valve 12 is pressed against the chemical substance capturing unit 3D of the inner cylinder unit 3B to open the valve, and the air inflow is performed. It is made to flow into the capsule K through the chamber 4, each communication hole 6, the pin insertion hole 9 and the air inflow hole H1. As a result, the air that has flowed into the capsule K becomes the air in which the chemical is mixed by stirring the chemical. Therefore, the air in which the chemical is mixed passes through the air outflow hole H2, the left and right chemical passages 19 and 19 to the left, By spraying from the right spray port 20, 20,
Drugs can be given to the patient's left and right nasal cavities simultaneously.

Further, since the air supplied from the pump portion 13 is accelerated in the pin insertion hole 9 by the first drilling pin 21, the chemical in the capsule K is effectively stirred by this accelerated air. can do. Further, the chemicals that fall from the inside of the capsule K are reduced by the first piercing pin 21, and the chemicals that have fallen are captured by the chemical capturing means 3D.

Thus, according to this embodiment, the capsule K
Attaching the movable member 8 to the movable member 8 and the second drilling pin 24
The air inflow hole H1 and the air outflow hole H2 can be easily formed in the axial direction of the capsule K by the operation of reciprocating once in the axial direction, and the preparatory operation up to the dispensing operation can be greatly simplified. On the top, the medicine in the capsule K is passed through the left and right medicine passages 19 and 19 to the left and right spray nozzles 1.

It is possible to surely perform the work of piercing the inflow hole H1 and prevent the poor injection of the air inflow hole H1 and the poor spraying of the chemical due to the unincorporated hole, and improve the reliability of the nasal drug dispenser 1. You can

When the capsule K is pushed into the capsule accommodating hole 11, when the air inlet H1 is opened in the capsule K, the fingertips 22A of the capsule guides 22 are used.
Since it is possible to prevent the capsule K from being pushed in more than a prescribed amount by being brought into contact with, it is possible to prevent damage to the capsule K due to forced pushing.

Further, by providing each capsule guide 22 on the opening side of the capsule accommodating hole 11, the capsule K can be guided to the capsule accommodating hole 11 by each of the capsule guides 22, so that the capsule K is accommodated in the capsule accommodating hole 11. It can be easily inserted into the inside, and the workability when inserting the capsule K can be improved.

Further, since each holding space portion 23 is formed between each capsule guide 22, by holding the capsule K through each holding space portion 23 after the administration is completed,
The capsule K can be easily taken out.

On the other hand, in the present embodiment, since the air inflow hole H1 and the air outflow hole H2 formed in the axial direction of the capsule K are drilled by the different drilling pins 21 and 24, respectively. The length dimension of the pins 21 and 24 can be shortened, and the length dimension of the whole nasal medication device 1 can be shortened.

Further, since all the tools for making holes in the capsule K are built in the medication device 1 itself, the medication operation can be performed without removing them at all. Not only can the operation be omitted, there is no risk of the punch being lost, and the handling is safer.

Further, even a small amount of the drug dropped from the capsule K can be captured by the drug capturing unit 3D of the fixing member 3, and the drug captured by the drug capturing unit 3D is supplied by the air from the pump unit 13 during the dispensing operation. However, since the drug can be supplied to the left and right nasal cavities of the patient together with the drug in the capsule K, the amount of the drug remaining in the nasal drug dispenser 1 can be reduced and the prescribed amount of the drug filled in the capsule K can be reduced. The drug can be reliably administered to the patient, and the frequency of cleaning the nasal medication device 1 can be reduced.

In the above embodiment, the case where the movable member 8 is provided with the pair of capsule guides 22, 22 has been exemplified. However, for example, as in the modification shown in FIG. You may make it provide the capsule guide 31 of a place.

Further, although the capsule guides 22 and 31 are formed as tubular bodies having substantially the same diameter as the tubular portion 8A of the movable member 8, the capsule guides may be formed into other tubular shapes such as a flat plate shape and a Gotoku shape. Good.

Further, in the above-mentioned embodiment, two chemical passages 19 and 19 are formed in the passage member 15 by branching left and right.
Although it has been described that the left and right spray ports 20 and 20 are simultaneously administered to both the left and right nasal cavity of the patient, the drug passage is
