特開2000-217919号公報
An aspirator that sucks a drug in a capsule through a mouthpiece after a capsule loaded with the drug is placed in a storage chamber and opens a hole in the capsule is often used in asthma patients and the like. In order to promote this, an inhalation-type dosing device in which a plurality of throttle passages and diffusion passages are alternately arranged in series is known (see, for example, Patent Document 1).
JP 2000-217919 A

ところで、上記のような従来の投薬器は、絞り通路の相互間に存在させている拡散通路内に薬剤が堆積して詰まり易く、それを取り除くには構成部材の分解が不可欠で手間がかかることに加え、絞り通路が複数存在するため比較的大きな吸引力を必要としており、この点に関して未だ改善の余地が残されていた。   By the way, in the above-mentioned conventional prescription device, the drug is likely to be deposited and clogged in the diffusion passage existing between the throttle passages, and disassembly of the constituent members is indispensable and troublesome to remove it. In addition, since a plurality of throttle passages exist, a relatively large suction force is required, and there is still room for improvement in this regard.

本発明の課題は、カプセルから取り出した薬剤を微細、分散化させて比較的小さな力で吸引することができる新規な吸引式投薬器を提案するところにある。   An object of the present invention is to propose a novel suction-type dispenser capable of finely dispersing a drug taken out from a capsule and sucking it with a relatively small force.

本発明は、薬剤を充填したカプセルを収納する収納室を備えたボディと、このボディの収納室に装填されたカプセルに孔を開けて薬剤を取り出す穿孔手段と、カプセルより取り出された薬剤を噴出経路を通して吸引するマウスピースとを備えた吸引式投薬器であって、
前記ボディとマウスピースとの相互間に、該ボディの出側経路及びマウスピースの噴出経路にそれぞれつながる出入り口を有しその内部空間にて薬剤を撹乱、破砕せしめて微細、分散化を図る分散室を設け、
前記分散室は、内部空間を区画形成する外周壁と、この外周壁によって区画形成された内部空間を複数領域に区分して迂回経路を形成する隔壁と、一端がマウスピースの噴出経路につながり他端を隔壁に連係させて迂回通路に接続する筒体からなり、
前記迂回通路は、前記出側経路に連通し前記分散室の噴出経路側で折り返して区画された経路を形成する入側域と、該入側域に連続し前記分散室の出側経路側で折り返すとともに前記筒体に接続して区画された経路を形成する出側域とからなる、ことを特徴とする吸引式投薬器である。
The present invention includes a body having a storage chamber for storing a capsule filled with a drug, a perforating means for opening a hole in the capsule loaded in the storage chamber of the body, and discharging the drug, and ejecting the drug extracted from the capsule A suction dispenser comprising a mouthpiece for suction through a path,
Dispersion chamber that has a doorway between the body and the mouthpiece, respectively connected to the exit path of the body and the ejection path of the mouthpiece, and that disrupts and crushes the drug in the internal space to achieve fine and dispersion Provided,
The dispersion chamber includes an outer peripheral wall that defines an internal space, a partition that divides the internal space defined by the outer peripheral wall into a plurality of regions and forms a detour path, and one end connected to the mouthpiece ejection path. Ri Do from the cylindrical body to be connected to the bypass passage is linked to an end to the partition wall,
The bypass passage communicates with the outlet side path to be folded back on the ejection path side of the dispersion chamber to form a partitioned path; and on the outlet side path side of the dispersion chamber continuous to the inlet side area. ing from the output side area and forming a path which is defined by connecting the cylinder with folding, it is suction type medicine administering apparatus according to claim.

分散室の内部空間を隔壁により複数領域に区分しマウスピースの噴出経路に至るまでの間の道のりを長くする迂回経路を設けるようにしたので、この経路を通る間に薬剤は十分に撹乱、破砕されることになる。   Since the internal space of the dispersion chamber is divided into multiple areas by partition walls and a detour path is provided to lengthen the path to the mouthpiece ejection path, the drug is sufficiently disturbed and crushed during this path Will be.

以下、図面を参照して本発明をより具体的に説明する。

図において1は投薬器の主要部を構成するボディである。このボディ1は軸心L(図2参照)に沿う対向位置の2箇所において両端が開放された筒体1′を例として示してあり、その内側には、図2に示すように仕切り壁1aによってカプセルを収納する収納室Mと、この収納室Mに開口hを通してつながる入側経路1b及び出側経路1cが形成されている。   In the figure, reference numeral 1 denotes a body that constitutes the main part of the dispenser. This body 1 is shown as an example of a cylindrical body 1 'having both ends opened at two opposing positions along the axis L (see FIG. 2), and inside the partition wall 1a as shown in FIG. Thus, a storage chamber M for storing the capsule, and an entrance side path 1b and an exit side path 1c connected to the storage chamber M through the opening h are formed.

2は筒体1′の開口部1dにつながるマウスピースである。このマウスピース2は外気と混合された薬剤を排出する末広がり形状になる噴出経路2aを有する。   Reference numeral 2 denotes a mouthpiece connected to the opening 1d of the cylinder 1 '. The mouthpiece 2 has an ejection path 2a having a divergent shape for discharging a medicine mixed with outside air.

3はボディ1とマウスピース2の相互間に設けられた分散室である。この分散室3は一方を他方に嵌合させて内部空間を区画形成する二分割形式の例で示した外周壁3a、3b(位置決め用の凹凸3a、3bを有する。図4参照)と、内部空間を、出側経路1cに連通し分散室3の噴出経路2a側で折り返して区画された経路を形成する入側域M 、及び入側域M に連続し分散室3の出側経路1c側で折り返すとともに後述する筒体3dに接続して区画された経路を形成する出側域Mに区分して迂回経路rを形成する隔壁3c(外周壁3bと一体物として表示)と、一端がマウスピース2の噴出経路2aの後端につながり他端を隔壁3cの端部に連係させて出側域Mにて迂回経路rに接続する筒体3dからなっており、外周壁3bには、ボディ1の出側経路1cにつながり内部空間の入側域Mで壁面に沿って薬剤を導入する入口(先細り形状の絞り通路)3eが形成されている。外周壁3a、3bの分解状態を薬剤の流れとともに図4に示す。 3 is a dispersion chamber provided between the body 1 and the mouthpiece 2. This dispersion chamber 3 has outer peripheral walls 3a and 3b (positioning irregularities 3a 1 and 3b 1 shown in FIG. 4) shown in an example of a two-part dividing type in which one is fitted to the other to form an internal space. , an inner space, out of the ingress area M 1, and continuous with the entry side area M 1 dispersion chamber 3 forms a path which is defined by folding in ejection path 2a side of the dispersion chamber 3 communicates with the outlet side passage 1c partition wall 3c to form a bypass route r by dividing the exit side area M 2 forming a path which is defined by connecting the tubular member 3d which will be described later with folding the side path 1c side (shown as the outer peripheral wall 3b and one piece) If, it has become a cylindrical body 3d having one end connected to the bypass route r at the outlet side region M 2 by linking the connection and the other end to the end portion of the partition wall 3c to the rear end of the ejection path 2a of the mouthpiece 2, the outer periphery the wall 3b, an inlet for introducing the agent along the wall surface on the outlet side path 1c of the body 1 at the entry side area M 1 ties interior space (tapered shape of the throttle passage) 3e is formed. FIG. 4 shows the state of decomposition of the outer peripheral walls 3a and 3b together with the flow of the medicine.

また、4は筒体1′のもう一方の開口部1eに設けられた蓋体である。この蓋体4はマウスピース2による吸引時にボディ1内への外気の導通を許容する逆止弁4aが配置されていて、連結部としての枢軸Pを介して筒体1′に開閉可能につながっている。連結部は枢軸Pに代えてヒンジを適用することもできる。   Reference numeral 4 denotes a lid provided in the other opening 1e of the cylinder 1 '. The lid 4 is provided with a check valve 4a that allows the outside air to pass into the body 1 when sucked by the mouthpiece 2, and can be opened and closed to the cylinder 1 'via a pivot P as a connecting portion. ing. A hinge may be applied to the connecting portion instead of the pivot P.

5は蓋体4の両側に一体的に設けられた係止片である(図1参照)。この係止片5の先端には爪部5aが設けられており、この爪部5aを、筒体1′に設けた開口で係止することで蓋体4を閉じた状態に保持する。   Reference numeral 5 denotes a locking piece provided integrally on both sides of the lid 4 (see FIG. 1). A claw portion 5a is provided at the tip of the locking piece 5, and the claw portion 5a is locked by an opening provided in the cylindrical body 1 'to hold the lid 4 in a closed state.

6はボディ1の収納室Mに配置されたカプセルに孔を開ける穿孔手段である。この穿孔手段6はボディ1に一体的あるいは別体としてつながるとともに上端部に開口を有する筒体6aと、この筒体6aの内側にてスプリングSの如き弾性部材にてスライド可能に支持され、上端部の開口より抜け出し不能に露出する押しボタン6bと、この押しボタン6bの孔部6b′に嵌合保持され、該押しボタン6bの押圧にて隔壁1aに形成された貫通孔hを通して収納室Mに先端部分を導入してカプセルの穿孔を行なうピン6cからなる。さらに、7は筒体6aの上端部でねじあるいはアンダーカットにより係合され押しボタン6bの抜け出しを防止する抜け止めキャップである。   6 is a punching means for making a hole in the capsule disposed in the storage chamber M of the body 1. The perforating means 6 is connected to the body 1 integrally or as a separate body, and is supported by an elastic member such as a spring S on the inside of the cylindrical body 6a having an opening at the upper end portion and slidable. The push button 6b exposed so as not to come out from the opening of the portion and the holding chamber M through the through hole h formed in the partition wall 1a by being fitted and held in the hole 6b ′ of the push button 6b. It consists of a pin 6c that introduces the tip portion into the hole to perforate the capsule. Further, reference numeral 7 denotes a retaining cap which is engaged with a screw or undercut at the upper end portion of the cylindrical body 6a to prevent the push button 6b from coming out.

上記の構成になる投薬器において、収納室M内に配置したカプセル内の薬剤を吸引するには、まず、押しボタン6bを押し込む。そうすると押しボタン6bにつながるピン6cがスプリングSの反発力に抗して収納室Mへと導入されその先端部分でカプセルに孔を開けることになる。   In the prescription device configured as described above, in order to suck the medicine in the capsule arranged in the storage chamber M, first, the push button 6b is pushed. Then, the pin 6c connected to the push button 6b is introduced into the storage chamber M against the repulsive force of the spring S, and a hole is opened in the capsule at the tip portion.

カプセルに孔を開けたのち、マウスピース2を口で咥え込んで吸気すると、図2中の矢印の如く逆止弁4aを通って外気が収納室M内へと流入し、カプセル内の薬剤と混合され、開口hを経て出側経路1cから入口3eを通って分散室3へと導入される。   After making a hole in the capsule, when mouthpiece 2 is swallowed by mouth, outside air flows into check chamber 4a through check valve 4a as shown by an arrow in FIG. 2, and medicine in the capsule And is introduced from the outlet side path 1c through the inlet 3e to the dispersion chamber 3 through the opening h.

分散室3では迂回経路rにより内部空間の道のりが十分に長くなっており、図2中の矢印の如き流れにより薬剤はそこを通る間に撹乱、破砕され、マウスピース2の噴出経路2aからは微細、分散化された薬剤として噴出することになる。   In the dispersion chamber 3, the path of the internal space is sufficiently long due to the detour path r, and the drug is disturbed and crushed by the flow shown by the arrow in FIG. 2, and from the ejection path 2a of the mouthpiece 2 It will be ejected as a fine, dispersed drug.

カプセルを収納室Mに配置するには、蓋体4の係止片5を両側から内側に向けて押し込みその爪部5aによるボディ1との連係を解除して図5に示すように、蓋体4を枢軸Pを基点にして回動させればよく、これにより収納室Mの入口Mが開となりカプセルを簡単に装填することができる。 In order to place the capsule in the storage chamber M, the locking piece 5 of the lid 4 is pushed inward from both sides to release the linkage with the body 1 by the claw portion 5a, as shown in FIG. 4 may be caused to rotate in the base point pivot P, thereby entrance M 1 of the storage room M is easily loaded capsules in an open.

本発明では、穿孔手段6をボディ1の軸心Lに対して直交する向きに設けたものを例として示したが、該穿孔手段6は、ボディ1の軸心に沿う向きに設けてもよく、この場合、筒体1′の開口部1d、1eの設置位置は該筒体1′の軸心Lに直交する向きに設ける等、適宜変更される。   In the present invention, the example in which the punching means 6 is provided in a direction orthogonal to the axis L of the body 1 is shown as an example, but the punching means 6 may be provided in a direction along the axis of the body 1. In this case, the installation positions of the openings 1d and 1e of the cylinder 1 'are appropriately changed, such as being provided in a direction orthogonal to the axis L of the cylinder 1'.

分散室3の隔壁3cについては、図4に示したように、円筒状のものの他にプレートを1枚若しくは複数枚組み合わせて構成してもよい。   As shown in FIG. 4, the partition wall 3c of the dispersion chamber 3 may be configured by combining one plate or a plurality of plates in addition to the cylindrical one.

また、迂回経路rは吸引力に影響しない範囲で3以上の領域に区分して形成することもできる。   Further, the detour route r can be formed by dividing it into three or more regions within a range not affecting the suction force.

薬剤のスムーズな流れを誘導するため、外周壁3a、3bの内壁は湾曲面を設けるのが好ましい。   In order to induce a smooth flow of the medicine, the inner walls of the outer peripheral walls 3a and 3b are preferably provided with curved surfaces.

図6はカプセルを縦置きにして収納するタイプの投薬器の例を示したものである。この場合には、穿孔手段6とボディ1とを枢軸Pを介して連結し枢軸Pを起点にして穿孔手段6を回動させて収納室Mを開放する。   FIG. 6 shows an example of a prescription device in which capsules are stored vertically. In this case, the perforating means 6 and the body 1 are connected via the pivot P, and the perforating means 6 is rotated around the pivot P to open the storage chamber M.

図7は収納室Mの出側経路1cの側壁及び底壁を含む末端壁に湾曲面8を形成した構造になる投薬器を示した図である。出側経路1cの末端壁に湾曲面8を形成することにより薬剤の流れがスムーズになり出側経路1c内において薬剤が堆積、固着するのを回避することができる。   FIG. 7 is a view showing a prescription device having a structure in which a curved surface 8 is formed on the end wall including the side wall and the bottom wall of the outlet side path 1c of the storage chamber M. FIG. By forming the curved surface 8 on the end wall of the outlet side path 1c, the flow of the drug becomes smooth, and it is possible to avoid the drug from being deposited and fixed in the outlet side path 1c.

カプセル内の薬剤を微細、分散化するとともに比較的小さな吸気力でもって薬剤の投与を行い得る吸引式投薬器が提供できる。   It is possible to provide an aspirating dispenser capable of finely dispersing the drug in the capsule and administering the drug with a relatively small inspiratory force.
