Abstract

The purpose of the present invention is to provide a fluid discharge member capable of effectively discharging a fluid using a simple structure. The fluid discharge member (100) has a fluid discharge section (2), a holder section (3), a protection section (4), and a connecting section (5). The fluid discharge section (2) has an exposed section (21) exposed from a container body (1) containing a fluid. The holder section (3) holds the fluid discharge section (2) at the end section of the inside of the container body (1) so that the exposed section (21) of the fluid discharge section (2) is exposed from the container body (1). The protection section (4) has a groove section (41) corresponding to the exposed section (21) of the fluid discharge section (2). The connecting section (5) connects the protection section (4) and the holder section (3) so that the groove section (41) of the protection section (4) covers the exposed section (21) of the fluid discharge section (2). The width of the material at the connecting section (5) is thinner than the holder section (3) and the protection section (4). Furthermore, by applying pressure to the protection section (4), the connecting section (5) breaks and the exposed section (21) of the fluid discharge section (2) is exposed. Thus, the fluid contained in the container body (1) is discharged from the exposed section (21) of the fluid discharge section (2) exposed from the container body (1).

Description

容器内の流体を所望の状態で吐出する使い捨て可能な流体吐出部材Disposable fluid ejection member for ejecting fluid in a container in a desired state
　本発明は，容器本体から一部が露出するように容器本体内に設けられた流体吐出部材に関する。
　本発明は，例えば，無針注射や噴霧器に用いられるアンプル内に設けられる流体吐出部材に関する。 The present invention relates to a fluid discharge member provided in a container body such that a part of the container body is exposed.
The present invention relates to a fluid discharge member provided in an ampoule used for needleless injection or a sprayer, for example.
　近年，注射針を有する注射器に代わるものとして，無針注射器が知られている。従来の無針注射器は，バイヤルから注射筒内に薬液を所定量吸引した後に，この薬剤を吸い込んだ注射筒を注入器に取り付け直す。その後，所定箇所に注射器を当てて薬剤を発射することにより，薬剤を高速で押し出して投与する。このように，薬剤を吸引し薬剤を発射するまでの注射器の取り扱いは煩雑である。また，薬剤を適量吸引して投与することは，必ずしも容易ではない。さらに，開口面にはウィルスなどが付着し，繁殖する可能性があり衛生面上の問題がある。そこで，１回投与する分の薬剤ごとに密封された薬剤を用意し，投与ごとに開封して投与することが好ましい。 In recent years, a needleless syringe is known as an alternative to a syringe having a syringe needle. In a conventional needleless syringe, a predetermined amount of liquid medicine is sucked into the syringe barrel from the vial, and then the syringe barrel into which the medicine has been sucked is reattached to the injector. Thereafter, the drug is ejected at a high speed by applying a syringe at a predetermined location and firing the drug. Thus, handling of the syringe until the drug is sucked and the drug is fired is complicated. In addition, it is not always easy to administer an appropriate amount of drug. Furthermore, there is a problem in terms of hygiene because viruses and the like may adhere to the opening surface and propagate. Therefore, it is preferable to prepare a sealed medicine for each medicine to be administered once, and to open and administer each medicine.
　このような無針注射器に用いられる使い捨てアンプルは，WO２００８／０５６４４２号公報に開示されている。このアンプルは，密封容器端部と容器本体部が別素材で形成されている。そして，容器本体部内に薬液が充填された後に，密封容器端部が，容器本体部に取り付けられ，容器本体部を密封する。また，密封容器端部は，アンプルを用いて薬液を投与する際に取り外される先端部を有する。アンプルは，容器本体部から密封容器端部の先端部の途中まで延びる連続した空間部を有し，先端部が取り外されると連続した空間部が開放端となり，薬液を噴出することができる。また，密封容器端部の先端部は，劈開により取り外される。 A disposable ampoule for use in such a needleless syringe is disclosed in WO 2008/056442. In this ampoule, the sealed container end and the container body are formed of different materials. And after a chemical | medical solution is filled in the container main-body part, a sealed container edge part is attached to a container main-body part, and seals a container main-body part. The end of the sealed container has a tip that is removed when a drug solution is administered using an ampoule. The ampoule has a continuous space extending from the container main body part to the middle of the front end of the sealed container end, and when the front end is removed, the continuous space becomes an open end and can eject the drug solution. The tip of the end of the sealed container is removed by cleavage.
　しかしながら，このような無針注射器用のアンプルのように，構成物品が微少なものである場合，容器本体部に密封容器端部を外部から嵌合するためには，正確で細かい作業が必要となる。従って，このようなアンプルを歩留まり良く製造するためには精密さが要求され，その製造装置も高価なものとなり易くなる。 However, when the component is very small, such as an ampoule for a needleless syringe, accurate and fine work is required to fit the sealed container end from the outside into the container body. Become. Therefore, in order to manufacture such an ampoule with high yield, precision is required, and the manufacturing apparatus tends to be expensive.
　また，使用に際して密封容器端部の先端部を取り外すとき，先端部に対して横方向から力を加える必要がある。このように，容器本体部に密封容器端部を外部から嵌合することとすると，先端部に対して力を加えたときに，密封容器端部とアンプルの嵌合部との間にズレが生じ，密封が保たれなくなり，液漏れの原因となる。 Also, when removing the tip of the sealed container end in use, it is necessary to apply force from the side to the tip. As described above, when the end of the sealed container is fitted to the container body from the outside, there is a gap between the end of the sealed container and the fitting part of the ampoule when a force is applied to the tip. Occurs, sealing is not maintained, causing liquid leakage.
　また，無針注射用のアンプルは，容器本体部内の薬液を速いスピードで噴射するものであるため，噴射の際には薬液の噴射方向に高い圧力がかかることとなる。このため，容器本体部に密封容器端部を外部から嵌合する構造とすると，その製作精度が不満足な密封容器端部であった場合には，噴射の際の圧力によって容器本体部に取り付けられた密封容器端部が外れる可能性がある。 In addition, since the ampule for needleless injection is for injecting the chemical solution in the container body at a high speed, a high pressure is applied in the injection direction of the chemical solution. For this reason, if the structure is such that the end of the sealed container is fitted to the container body from the outside, if the end of the sealed container is unsatisfactory in its manufacturing accuracy, it is attached to the container body by the pressure during injection. The end of the sealed container may come off.
　また，このアンプルには，容器本体部から密封容器部の先端部の途中まで延びる連続した空間部を設けられ，劈開によって先端部を取り外すことで薬液の噴出口を形成することとしている。このような構成の場合，先端部を取り外すことで形成された噴出口周りの開口面を，患者の肌などに押し当てて，薬液を噴出することとなる。従って，密封容器部の先端部の劈開性が十分でなく，開口面にささくれ等が残るような場合，その開口面を押しつけた患者の肌を傷つけることとなっていた。 Also, this ampoule is provided with a continuous space extending from the container body part to the middle of the tip part of the sealed container part, and the tip part is removed by cleaving to form a jet of chemical liquid. In such a configuration, the medical solution is ejected by pressing the opening surface around the ejection port formed by removing the tip portion against the patient's skin or the like. Therefore, when the cleaving property of the front end of the sealed container portion is not sufficient and a prickling or the like remains on the opening surface, the patient's skin pressing the opening surface is damaged.
　また，このアンプルのように，先端部を取り外すことで生ずる断面を吐出口として利用すると、その吐出口の形状，すなわち凹凸や寸法（長さや口径）が変化して、流体の吐出が不安定になる可能性が考えられる。すなわち，無針注射器であれば、流体が表皮を貫通するためには，威力があり乱れのない極細い流体の流れが必要となる。また，噴霧器であれば、流体をきれいに霧状に広がるために，急激な絞り込みと開放を行う整った吐出口が必要となる。 In addition, if the cross section generated by removing the tip is used as a discharge port, such as this ampoule, the shape of the discharge port, that is, unevenness and dimensions (length and diameter) change, and fluid discharge becomes unstable. It is possible that That is, in the case of a needleless syringe, in order for the fluid to penetrate the epidermis, an extremely fine fluid flow that is powerful and free from turbulence is required. In addition, in the case of a nebulizer, in order to spread the fluid neatly, a neat discharge port that performs rapid constriction and opening is required.
　また，このようなアンプルは，密封容器段部の中に，例えば直径０．０１ｍｍ～０．５ｍｍの細孔を貫通させずに片持ちで開口することとしており，これは難易度の高い細工と言える。 In addition, such ampules are opened in a cantilevered manner without penetrating pores having a diameter of 0.01 mm to 0.5 mm, for example, in a sealed container step, which is difficult to work with. I can say that.

　本発明に係る流体吐出部材１００（２００）は，流体吐出部２と，保持部３と，保護部４と，連結部５とを含む。流体吐出部２は，流体が収容される容器本体１から露出する露出部２１を有する。保持部３は，流体吐出部２の露出部２１が容器本体１から露出するように，流体吐出部２を，容器本体１内の一端部に保持する。保護部４は，流体吐出部２の露出部２１に対応する大きさの溝部４１を有する。連結部５は，保護部４の溝部４１が，流体吐出部２の露出部２１を覆うように，保護部４と保持部３とを連結する。連結部５は，保持部３及び保護部４より，素材の厚みが薄くなっている。そして，保護部４に対して力を加えることで，連結部５が破損し，流体吐出部２の露出部２１が露出される。これにより，容器本体１から露出された流体吐出部２の露出部２１から，容器本体1内に収容される流体が，吐出する。[Correction 28.08.2012 under Rule 91]
A fluid ejection member 100 (200) according to the present invention includes a fluid ejection part 2, a holding part 3, a protection part 4, and a connecting part 5. The fluid discharge part 2 has an exposed part 21 exposed from the container body 1 in which the fluid is accommodated. The holding part 3 holds the fluid discharge part 2 at one end in the container main body 1 so that the exposed part 21 of the fluid discharge part 2 is exposed from the container main body 1. The protection part 4 has a groove part 41 having a size corresponding to the exposed part 21 of the fluid discharge part 2. The connection part 5 connects the protection part 4 and the holding part 3 so that the groove part 41 of the protection part 4 covers the exposed part 21 of the fluid discharge part 2. The connecting portion 5 is made of a material thinner than the holding portion 3 and the protecting portion 4. Then, by applying a force to the protection part 4, the connecting part 5 is broken and the exposed part 21 of the fluid discharge part 2 is exposed. Thereby, the fluid accommodated in the container main body 1 is discharged from the exposed portion 21 of the fluid discharge portion 2 exposed from the container main body 1.
　このような構成を有していることにより，本発明に係る流体吐出部材は，容器本体の一端から容器本体内に挿入し，容器本体の他端まで押し込むようにして，容器本体内に取り付けることができる。従って，容器密閉部を容器本体に対して外部から嵌合させるような精密な作業を省略することができる。これにより，流体吐出部材を容器本体に取り付けることが容易になる。 With such a configuration, the fluid discharge member according to the present invention is inserted into the container body from one end of the container body, and is attached to the container body so as to be pushed into the other end of the container body. Can do. Accordingly, it is possible to omit a precise operation for fitting the container sealing portion to the container main body from the outside. Thereby, it becomes easy to attach the fluid discharge member to the container body.
　また，本発明に係る流体吐出部材は，容器本体内に取り付けられている。これにより，流体吐出部材は安定する。従って，使用に際して，流体吐出部材に設けられた保護部を取り外すために，保護部に対し力を加えたとしても，流体吐出部材ごと外れてしまうことがない。 Further, the fluid discharge member according to the present invention is attached in the container body. Thereby, the fluid discharge member is stabilized. Therefore, in use, even if a force is applied to the protective part to remove the protective part provided on the fluid discharge member, the fluid discharge member does not come off.
　また，本発明に係る流体吐出部材は，容器本体内の端部に取り付けられているため，容器本体内に充填された流体を吐出する際に，流体吐出部材に対して高い圧力がかかる場合であっても，流体吐出部材が容器本体から外れることがない。 In addition, since the fluid discharge member according to the present invention is attached to the end portion in the container body, when the fluid filled in the container body is discharged, a high pressure is applied to the fluid discharge member.

　本発明の好ましい態様においては，流体吐出部２の中心軸に沿って，容器本体１内の流体を容器本体２の外部へ吐出するための，流路２２が設けられる。そして，流路２２は，容器本体１の内側から外側にすすむにつれて，先細となっている。このような構成とすることにより，流路２２を流通して吐出される流体の吐出速度を上げることができる。[Correction 28.08.2012 under Rule 91]
In a preferred embodiment of the present invention, a flow path 22 for discharging the fluid in the container body 1 to the outside of the container body 2 is provided along the central axis of the fluid discharge portion 2. The flow path 22 tapers as it progresses from the inside to the outside of the container body 1. With such a configuration, it is possible to increase the discharge speed of the fluid discharged through the flow path 22.
　本発明の好ましい態様は，流体吐出部２の露出部２１を，円錐台形状に隆起させる。また，流体吐出部２の流路２２の先細となる部分を延長してできた円錐形の頂角を，鋭角とする。例えば，本発明を無針注射器用のアンプルに用いるような場合，流体吐出部２の露出部２１が円錐台形状に隆起しているため，露出部２１を投薬される患者の肌により密着させることができる。なお，露出部２１は，予め開口面を美麗に形成することができ，かつ，保護部によって保護されているため，投薬される患者の肌を傷つけることがない。また，流体吐出部２の流路２２の先細となる部分を延長してできた円錐形の頂角を，鋭角とすることにより，吐出される流体の進入速度を上げることができる。従って，本発明の好ましい態様に係る流体吐出部材は，例えば無針注射器のような，より高い流体吐出速度を要求するもののアンプル内に適用することができる。 In a preferred embodiment of the present invention, the exposed portion 21 of the fluid discharge portion 2 is raised in a truncated cone shape. In addition, the apex angle of the conical shape formed by extending the tapered portion of the flow path 22 of the fluid discharge unit 2 is defined as an acute angle. For example, when the present invention is used for an ampoule for a needleless syringe, the exposed portion 21 of the fluid discharge portion 2 is raised in a truncated cone shape, so that the exposed portion 21 is brought into close contact with the skin of the patient to be administered. Can do. In addition, since the exposed part 21 can form the opening surface beautifully beforehand and is protected by the protection part, the patient's skin to be administered is not damaged. Further, by setting the apex angle of the conical shape formed by extending the tapered portion of the flow path 22 of the fluid discharge unit 2 to an acute angle, the speed of entry of the discharged fluid can be increased. Therefore, the fluid ejection member according to a preferred embodiment of the present invention can be applied to an ampoule that requires a higher fluid ejection speed, such as a needleless syringe.
　本発明の好ましい態様は，流体吐出部２の露出部２１を，円錐台形状に窪ませる。また，流体吐出部２の流路２２の先細となる部分を延長してできた円錐形の頂角を，鈍角とする。例えば，本発明を流体噴霧用のアンプルに用いるような場合，流体吐出部２の露出部２１が円錐台形状に窪んでいるため，容器本体内の流体をより広範囲に噴霧することができる。また，流体吐出部２の流路２２の先細となる部分を延長してできた円錐形の頂角が，鈍角であるため，急激に絞り込まれた流体が連続して開放されることとなる。従って，容器本体内の流体をより広範囲に噴霧させることができる。 In a preferred embodiment of the present invention, the exposed portion 21 of the fluid discharge portion 2 is recessed in a truncated cone shape. Further, the apex angle of the conical shape formed by extending the tapered portion of the flow path 22 of the fluid discharge part 2 is defined as an obtuse angle. For example, when the present invention is used in an ampule for fluid spraying, the exposed portion 21 of the fluid discharge portion 2 is recessed in a truncated cone shape, so that the fluid in the container body can be sprayed in a wider range. Further, since the apex angle of the conical shape formed by extending the tapered portion of the flow path 22 of the fluid discharge unit 2 is an obtuse angle, the fluid that has been rapidly narrowed is continuously released. Therefore, the fluid in the container body can be sprayed in a wider range.
　本発明の好ましい態様は，流路２２を流通する流体の回転方向を制御する回転溝２２ａを，流路２２の内壁に設ける。図６（ａ）及び（ｂ）は，回転溝２２ａが３つ設けられた流路の例を示している。回転溝２２aは，例えば，３つ，４つ，５つ，又はそれ以上設けることとしてもよい。このような構成を有することにより，本発明は，流路２２を流通する流体を回転させることができる。従って，例えば，本発明を流体噴霧用のアンプルに用いる場合，流路２２を流通する流体が吐出口から回転方向に広がって噴霧されるため，より広範囲に流体を噴霧することができる。なお，回転溝２２ａは，流路２２の内壁の一部を窪ませることにより形成することとしてもよいし，流路の内壁一部を隆起させることにより形成することとしてもよい。また，回転溝２２ａは，流路２２（流体吐出部２）と同一の素材で一体形成することとしてもよいし，流路２２（流体吐出部２）とは別の素材で形成することとしてもよい。 In a preferred embodiment of the present invention, a rotation groove 22 a for controlling the rotation direction of the fluid flowing through the flow path 22 is provided on the inner wall of the flow path 22. 6A and 6B show an example of a flow path provided with three rotation grooves 22a. For example, three, four, five, or more rotation grooves 22a may be provided. By having such a configuration, the present invention can rotate the fluid flowing through the flow path 22. Therefore, for example, when the present invention is used in an ampule for fluid spraying, the fluid flowing through the flow path 22 spreads in the rotation direction from the discharge port and is sprayed, so that the fluid can be sprayed in a wider range. The rotating groove 22a may be formed by recessing a part of the inner wall of the flow path 22, or may be formed by raising a part of the inner wall of the flow path. Further, the rotating groove 22a may be integrally formed with the same material as the flow path 22 (fluid discharge part 2), or may be formed with a different material from the flow path 22 (fluid discharge part 2). Good.
　本発明の好ましい態様は，保持部３と保護部４を，連結部５を介して，一体成形する。このように一体成形することにより，容器本体内の気密性を高めることができるため，衛生面において好ましい。また，素材加工上の問題がなければ，容器本体１，保持部３，保護部４，及び連結部５を一体形成するアンプルとしてもよい。 In a preferred embodiment of the present invention, the holding portion 3 and the protection portion 4 are integrally formed through the connecting portion 5. By integrally molding in this way, the airtightness in the container body can be improved, which is preferable in terms of hygiene. Moreover, if there is no problem in material processing, it is good also as an ampoule which integrally forms the container main body 1, the holding part 3, the protection part 4, and the connection part 5.

The fluid discharge device according to another aspect of the present invention preferably further includes a deflector block 700 disposed in the ampoule 1 in proximity to the fluid discharge member. The deflector block 700 has an outer peripheral wall having substantially the same diameter as the inner wall in the ampoule 1, and a diversion groove 710 is formed on the outer peripheral wall. The deflector block 700 is a member for diverting the fluid in the container body to which the pressure is applied by the movable stopper 300. When the divided fluids are ejected from the fluid ejection port 23, they interfere with each other and become sprayed. The deflector block 700 is used by being loaded in an ampoule, and is formed with the same or substantially the same diameter as the inner wall of the ampoule so that the fluid in the ampoule does not flow from other than the diversion groove 710.

The embodiments of the present invention described below are examples, and the present invention is not limited to the following examples, and includes modifications made within the scope obvious to those skilled in the art from the present specification.
（１．第１の実施の形態）
　図１は，本発明の第１の実施の形態に係る流体吐出部材１００の基本構成を示す概略図である。本発明の第１の実施の形態は，例えば，無針注射器のような，容器本体内の流体を，勢いよく一点に集中させて吐出することを要する器具の容器本体内に取り付けられる流体吐出部材に関する。 (1. First embodiment)
FIG. 1 is a schematic diagram showing a basic configuration of a fluid ejection member 100 according to the first embodiment of the present invention. In the first embodiment of the present invention, for example, a fluid discharge member attached to a container body of a device such as a needleless syringe that requires the fluid in the container body to be concentrated and discharged at one point. About.
　図１に示されるように，流体吐出部材１００は，流体吐出部２と，保持部３と，保護部４と，連結部５とを有する。流体吐出部２は，流体が収容される容器本体１から露出する露出部２１を有する。保持部３は，流体吐出部２の露出部２１が容器本体１から露出するように，流体吐出部２を，容器本体１内の一端に保持する。保護部４は，流体吐出部２の露出部２に対応する大きさの溝部４１を有する。連結部５は，保護部４の溝部４１が，流体吐出部２の露出部２１を覆うように，保護部４と保持部３とを連結する。連結部５は，保持部３及び保護部４より，素材の厚みが薄くなっている。そして，保護部４に対して力を加えることで，連結部５が破損し，流体吐出部２の露出部２１が露出される。これにより，容器本体１から露出された流体吐出部２の露出部２１から，容器本体１内に収容される流体が，吐出するようになる。 As shown in FIG. 1, the fluid ejection member 100 includes a fluid ejection part 2, a holding part 3, a protection part 4, and a connection part 5.

　図１に示すように，流体吐出部材１００は，容器本体１の内部に取り付けられている。この，容器本体１は，例えば，無針注射器に用いられるアンプルであってもよい。また，容器本体１は，流体吐出部材１００が取り付けられた端部と反対側の端部が，流体を供給する供給源（例えば蛇口）と結合する筒状の部材であっても良い。 (1-1. Container body)
As shown in FIG. 1, the fluid ejection member 100 is attached inside the container body 1. The container body 1 may be an ampoule used for a needleless syringe, for example. Further, the container body 1 may be a cylindrical member whose end opposite to the end to which the fluid discharge member 100 is attached is coupled to a supply source (for example, a faucet) that supplies fluid.
　容器本体１には，その内部に流体を容れることが予定されている。容器本体１内に容れられる流体は，薬液であってもよい。なお，容器本体部には，比較的弾力性に富む樹脂を用いることで，クラックが生ずる事態を効果的に防止することができる。本発明の好ましい態様における容器本体１は，カートリッジ式のアンプルである。すなわち，このアンプルは，無針注射ユニットなどに挿入され，このアンプルを使用した後は別のアンプルと交換するものである。 The container body 1 is scheduled to contain fluid. The fluid contained in the container body 1 may be a chemical solution. In addition, the case where a crack arises can be prevented effectively by using resin with comparatively rich elasticity for the container body. The container body 1 in a preferred embodiment of the present invention is a cartridge type ampoule. That is, this ampoule is inserted into a needle-free injection unit or the like, and is exchanged for another ampoule after using this ampoule.

（１－２．流体吐出部）
　流体吐出部２は，容器本体１内に充填される流体を吐出するための部材である。流体吐出部２には，容器本体１内に充填される流体を吐出するための流路２２が設けられる。流路２２は，流体吐出部２に一つ設けられてもよいし，複数設けられることとしても良い。また，流体吐出部２を，スポンジのような吸水性のある部材で構成し，容器本体１内の流体が一端から吸収され，他端から染み出すように吐出されることとしても良い。[Correction 28.08.2012 under Rule 91]
(1-2. Fluid discharge part)
The fluid discharge unit 2 is a member for discharging the fluid filled in the container body 1. The fluid discharge unit 2 is provided with a flow path 22 for discharging the fluid filled in the container body 1. One flow path 22 may be provided in the fluid discharge section 2 or a plurality of flow paths 22 may be provided. Moreover, the fluid discharge part 2 is comprised with a member with water absorption like a sponge, and it is good also as the fluid in the container main body 1 being absorbed from one end, and discharging so that it may ooze out from the other end.
　図１は，流体吐出部材１００が，無針注射器のような容器本体内の流体を勢いよく一点に集中させて吐出することを要する器具に取り付けられた例を示す図である。流体吐出部２には，流体吐出部２の中心軸に沿って一の流路２２が貫通形成される。貫通形成された流路２２は，その両端が開放端とされ，容器本体外側が流体吐出口２３となる。流体吐出口２３の口径は，０．０１～０．１５ｍｍ，０．１ｍｍ～０．３ｍｍ，０．１５ｍｍ～０．２５ｍｍ又は０．２ｍｍであってもよい。流路２２は，流体吐出部２の容器本体内側から流体吐出口２３側に進むにつれて先細となっていることが好ましい。また，流路２２の先細となる部分を延ばしてできた円錐形の頂角は，鋭角となっていることが好ましい。換言すると，貫通形成された流路２２の空間を延ばしてできた円錐形の頂角が，鋭角となっていることが好ましい。 FIG. 1 is a view showing an example in which the fluid discharge member 100 is attached to a device such as a needleless syringe that requires the fluid in the container body to be concentrated and discharged at one point. A single flow path 22 is formed through the fluid discharge unit 2 along the central axis of the fluid discharge unit 2. The both ends of the channel 22 formed to be open are open ends, and the outer side of the container body is a fluid discharge port 23. The diameter of the fluid discharge port 23 may be 0.01 to 0.15 mm, 0.1 mm to 0.3 mm, 0.15 mm to 0.25 mm, or 0.2 mm. It is preferable that the flow path 22 is tapered as it proceeds from the inside of the container main body of the fluid discharge unit 2 toward the fluid discharge port 23. Moreover, it is preferable that the apex angle of the conical shape formed by extending the tapered portion of the flow path 22 is an acute angle. In other words, it is preferable that the apex angle of the conical shape formed by extending the space of the passage 22 formed to be an acute angle.
　流路を形成する円錐形の頂角は，例えば１度～４５度があげられ，好ましくは５度～３０度であり，より好ましくは１０度～２０度であるが，５度～１０度であってもよい。流体力学的な観点からは頂角（絞り）を１５度程度とすれば，損失を小さくすることができると考えられている。このような角度であれば，流体を調整し，流路２２を流通する流体の流通速度を上げることができる。また，円錐形の頂角の角度を調節することにより，流体の貫通力や進入速度を調整することができる。例えば，無針注射器の場合であれば，薬剤を皮膚のより深い部分へと注入することもできるし，皮膚の浅い部分へと注入することもできる。また，本発明の流体吐出部材１００が，無針注射器に用いられた場合，薬液が分布する範囲が広いと皮膚内の痛点を通過する可能性が高くなり，無痛ではなくなる可能性がある。そのような観点からは，円錐形の頂角を１度～１０度，又は５度～１０度としてもよい。 The apex angle of the conical shape forming the flow path is, for example, 1 to 45 degrees, preferably 5 to 30 degrees, more preferably 10 to 20 degrees, but 5 to 10 degrees. There may be. From the viewpoint of hydrodynamics, it is considered that the loss can be reduced by setting the apex angle (aperture) to about 15 degrees. With such an angle, the fluid can be adjusted and the flow rate of the fluid flowing through the flow path 22 can be increased. In addition, by adjusting the apex angle of the conical shape, the fluid penetration force and the approach speed can be adjusted. For example, in the case of a needleless syringe, the drug can be injected into a deeper part of the skin or can be injected into a shallow part of the skin. In addition, when the fluid ejection member 100 of the present invention is used in a needleless syringe, if the range in which the drug solution is distributed is wide, the possibility of passing through pain points in the skin increases, and there is a possibility that it is not painless. From such a viewpoint, the apex angle of the cone may be 1 to 10 degrees, or 5 to 10 degrees.
　また，図３は，流路２２を流通する流体の流れの様子を示している。例えば，図３（ａ）に示すように，流路２２を形成する円錐形の頂角を４５度程度とした場合，流路２２を流通する流体は，吐出口２３から吐出する際に，互いに干渉し合い，ある程度散散して吐出される。従って，流路２２を形成する円錐形の頂角を４０度～５０度としたものを，例えば無針注射器に用いる場合，皮膚の浅い箇所に薬剤を注入することができる。また，例えば，図３（ｂ）に示すように，流路を形成する円錐形の頂角を１５度程度とした場合，流路２２を流通する流体は，吐出口２３から吐出する際に，流れが収束されて集中して吐出される。また，図３（ｂ）に示す流体吐出部２の流路２２は，その全長が２．５ｍｍ～３ｍｍ程度とされており，例えば無針注射器に用いる場合，軟質な皮膚を貫通させる適切な圧力で流体を吐出することができる。一方，図３（ｃ）に示す流体吐出部２の流路２２は，その全長が３．５ｍｍ～４ｍｍ程度とされている。このような場合には，圧力損失が生じることとなるため流速を弱めることができる。このように，流路２２を形成する円錐形の頂角及び流路の全長を調整することにより，吐出される流体の性質及び圧力を制御することが可能である。なお，このように，流路２２の形状が微細に異なるだけでも，吐出口２３から吐出する流体の状態が大きく異なる。従来のアンプルは，先端部を取り外すことで生ずる断面を吐出口として利用していたが，これでは先端部を取り外す際に，吐出口の形状が破損等により変化してしまうため，アンプルの用途に応じた所望の状態で流体を吐出することが困難である。そこで，本発明に係る流体吐出部材１００のように，予め流路２２及び吐出口２３を精度よく形成しておき，それを保護部によって保護しておくことにより，常にアンプルの用途に応じた所望の状態で流体を吐出することができるように，流路２２及び吐出口２３の形状を維持しておくことができる。 FIG. 3 shows the flow of fluid flowing through the flow path 22. For example, as shown in FIG. 3A, when the apex angle of the conical shape forming the flow channel 22 is about 45 degrees, the fluid flowing through the flow channel 22 is mutually discharged when discharged from the discharge port 23. Interfering with each other and discharged to some extent. Accordingly, when the apex angle of the conical shape forming the flow path 22 is 40 degrees to 50 degrees, for example, in a needleless syringe, the drug can be injected into a shallow portion of the skin. For example, as shown in FIG. 3B, when the apex angle of the conical shape forming the flow path is about 15 degrees, the fluid flowing through the flow path 22 is discharged from the discharge port 23. The flow is converged and discharged in a concentrated manner. Further, the flow path 22 of the fluid discharge section 2 shown in FIG. 3B has a total length of about 2.5 mm to 3 mm. For example, when used in a needleless syringe, an appropriate pressure that penetrates soft skin is used. Can discharge fluid. On the other hand, the total length of the flow path 22 of the fluid discharge section 2 shown in FIG. 3C is about 3.5 mm to 4 mm. In such a case, pressure loss occurs, so the flow velocity can be reduced. In this way, by adjusting the apex angle of the conical shape forming the flow path 22 and the total length of the flow path, it is possible to control the properties and pressure of the discharged fluid. In this way, even if the shape of the flow path 22 is slightly different, the state of fluid discharged from the discharge port 23 is greatly different. Conventional ampules used the cross section produced by removing the tip as a discharge port. However, when the tip is removed, the shape of the discharge port changes due to breakage, etc. It is difficult to discharge the fluid in a desired state. Therefore, as in the fluid discharge member 100 according to the present invention, the flow path 22 and the discharge port 23 are accurately formed in advance and protected by the protection unit, so that it is always desired according to the application of the ampoule. The shape of the flow path 22 and the discharge port 23 can be maintained so that the fluid can be discharged in this state.
　また，流体吐出部２は，容器本体１及び保持部３とは別の素材で形成されることができる。また，流体吐出部２を形成する素材は，容器本体１及び保持部３を形成する素材と比較し，硬質なものを用いることができる。例えば，容器本体１及び保持部材３を比較的弾力性の富むシリコーン樹脂により形成した場合，流体吐出部２は，比較的強硬な樹脂やガラスを用いて形成することができる。従来の無針注射器ようのアンプルでは，これらの容器本体や流体吐出部は同じ素材で一体形成されていたが，本発明のように容器本体１及び保持部材３とは別に，流体吐出部を比較的強硬な素材で形成することにより，流路を流通する流体をより安定させることができる。すなわち，容器本体１内の流体を高圧で吐出させるためには，損失をなるべく小さくし，流路中の流れの剥離現象が生ずる事態をできる限り防止することが好ましいが，このように，流路を形成する素材が強硬なものであれば，流体が高圧で流路中を流通したとしても剥離現象を防止することができる。 Further, the fluid discharge part 2 can be formed of a material different from the container main body 1 and the holding part 3. Further, the material forming the fluid discharge unit 2 can be harder than the material forming the container body 1 and the holding unit 3. For example, when the container main body 1 and the holding member 3 are formed of a relatively elastic silicone resin, the fluid discharge portion 2 can be formed using a relatively hard resin or glass. In a conventional ampule such as a needleless syringe, these container body and fluid discharge part are integrally formed of the same material, but the fluid discharge part is compared with the container body 1 and the holding member 3 as in the present invention. By forming the material with a strong material, the fluid flowing through the flow path can be made more stable. That is, in order to discharge the fluid in the container body 1 at a high pressure, it is preferable to reduce the loss as much as possible and prevent the occurrence of the flow separation phenomenon in the flow path as much as possible. If the material forming the material is hard, the peeling phenomenon can be prevented even if the fluid circulates in the flow path at a high pressure.
　流体吐出部２は，容器本体１から露出する露出部２１を有する。図１において，露出部２１は，流体吐出口２３を中心に，円錐台形状に隆起している。円錐台形状の部分の高さは，例えば流体吐出部２全体の１０％～９０％があげられ，２０％～８０％，３０％～７０％でもよい。また台形の頂角の角度は，例えば１００度～１７０度があげられ，１２０度～１５０度，１３０度～１４０度でもよい。このように，露出部２１が，流体吐出口２３を中心に円錐台形状に隆起させることにより，例えば，本発明の流体吐出部材１００が無針注射器に用いられる場合に，露出部２１の中心に位置する流体吐出口２３を，より皮膚に密着させることができる。従って，流体吐出口２３から薬剤を漏らさずに，皮膚内に薬液を注入することができる。 The fluid discharge part 2 has an exposed part 21 exposed from the container body 1. In FIG. 1, the exposed portion 21 protrudes in a truncated cone shape around the fluid discharge port 23. The height of the frustoconical portion is, for example, 10% to 90% of the entire fluid discharge unit 2, and may be 20% to 80%, 30% to 70%. Further, the vertex angle of the trapezoid is, for example, 100 degrees to 170 degrees, and may be 120 degrees to 150 degrees, 130 degrees to 140 degrees. As described above, the exposed portion 21 is raised in the shape of a truncated cone with the fluid discharge port 23 as the center, so that, for example, when the fluid discharge member 100 of the present invention is used in a needleless syringe, It is possible to make the fluid discharge port 23 positioned closer to the skin. Therefore, the chemical solution can be injected into the skin without leaking the drug from the fluid discharge port 23.
　流体吐出部２の容器本体内側の端部には，フランジが形成されている。このフランジを保持部３に押しつけるようにして，流体吐出部２の胴体を，円筒状に形成された保持部３の中空空間に挿入する。このようにして，流体吐出部２と保持部３を結合させることとしてもよい。 A flange is formed at the inner end of the fluid discharge unit 2 inside the container body. The body of the fluid discharge unit 2 is inserted into the hollow space of the holding unit 3 formed in a cylindrical shape by pressing the flange against the holding unit 3. In this way, the fluid discharge unit 2 and the holding unit 3 may be combined.

（１－３．保持部）
　図１に示すように，保持部３は，流体吐出部２の露出部２１が容器本体１から露出するよう，流体吐出部２を容器本体１内に保持する。保持部３は，円筒状に形成され，胴体部３１，胴体部上部３２，窪み部３３からなる。胴体部上部３２の直径は，胴体部３１の直径より小さくなっている。容器本体１の開放端側の開放部は，保持部３の胴体部上部３２の直径と略同径の開放部とされており，この容器本体１の開放部に，保持部３の胴体上部３２が押し込まれるようにして嵌着される。このような構成であれば，容器本体１に保持部３（流体吐出部材１００）を取り付けることが容易である。また，保持部３の窪み部３３は，胴体部３１の外周壁が一部欠けるように形成されている。この保持部３の窪み部３３に対応して，容器本体１の内壁は，一部突起するように形成されている。従って，保持部３の胴体上部３２が，容器本体１の開放部に押し込まれるようにして嵌着された際，保持部３の窪み部３３に，容器本体の突起部が嵌り込むようになっている。このようにして，保持部３を，容器本体１内に取り付けることとしてもよい。なお，素材の加工上や使用上の問題がなければ，容器本体１と保持部３を一体成型することとしても良い。[Correction 28.08.2012 under Rule 91]
(1-3. Holding part)
As shown in FIG. 1, the holding unit 3 holds the fluid discharge unit 2 in the container body 1 so that the exposed portion 21 of the fluid discharge unit 2 is exposed from the container body 1. The holding part 3 is formed in a cylindrical shape and includes a body part 31, a body part upper part 32, and a hollow part 33. The diameter of the body part upper part 32 is smaller than the diameter of the body part 31. The open part on the open end side of the container body 1 is an open part having a diameter substantially the same as the diameter of the upper part 32 of the body part of the holding part 3, and the upper part 32 of the body part of the holding part 3 is connected to the open part of the container body 1. Is inserted and pushed. If it is such a structure, it will be easy to attach the holding | maintenance part 3 (fluid ejection member 100) to the container main body 1. FIG. Further, the recessed portion 33 of the holding portion 3 is formed such that a part of the outer peripheral wall of the body portion 31 is missing. Corresponding to the recess 33 of the holding part 3, the inner wall of the container body 1 is formed so as to partially protrude. Therefore, when the body upper part 32 of the holding part 3 is fitted so as to be pushed into the open part of the container main body 1, the protrusion of the container main body is fitted into the recess 33 of the holding part 3. Yes. In this way, the holding unit 3 may be attached in the container body 1. If there is no problem in processing or using the material, the container body 1 and the holding part 3 may be integrally formed.

　保持部３の容器本体内側の端部は，保持している流体吐出部２の流路２２を中心として，円弧状に窪むように形成されていても良い。また。保持部３の一端部が円弧状に窪んでいることに対応して，これに保持される流体吐出部２の一端部を円弧状に窪ませることとしてもよい。また，保持部３の容器本体内側の端部は，保持している流体吐出部２の流路２２を中心として，多角形状に窪むように形成されていても良い。このように，円弧状又は多角形状に窪むように形成されていることにより，保持部３により保持される流体吐出部２の流路２２に，容器本体１内の流体が流れ込み易くなる。また，容器本体１内の流体を押し出す部材の形状（例えば，図９に示す可動栓３００の端部の形状）に，対応させた形状とすることにより，容器本体１内の流体を完全に吐出させることができる。[Correction 28.08.2012 under Rule 91]
The inner end of the container main body of the holding unit 3 may be formed so as to be recessed in an arc shape around the flow path 22 of the fluid discharge unit 2 being held. Also. Corresponding to the fact that one end portion of the holding portion 3 is recessed in an arc shape, one end portion of the fluid discharge portion 2 held by the holding portion 3 may be recessed in an arc shape. Further, the end of the holding unit 3 inside the container main body may be formed to be recessed in a polygonal shape with the flow path 22 of the holding fluid discharge unit 2 as the center. As described above, by being formed so as to be recessed in an arc shape or a polygonal shape, the fluid in the container body 1 can easily flow into the flow path 22 of the fluid discharge portion 2 held by the holding portion 3. Further, by making the shape corresponding to the shape of the member for extruding the fluid in the container body 1 (for example, the shape of the end of the movable stopper 300 shown in FIG. 9), the fluid in the container body 1 is completely discharged. Can be made.
　保持部３の胴体部上部３２の上面は，接続部５を介して，保護部４と連結されている。保持部３と保護部４は，接続部を介して，一体的に形成されていることが好ましい。 The upper surface of the body part upper part 32 of the holding part 3 is connected to the protection part 4 through the connection part 5. It is preferable that the holding part 3 and the protection part 4 are integrally formed via the connection part.
（１－４．保護部）
　図１に示すように，保護部４は，流体吐出部２の露出部２１を保護するために設けられ，使用に際して取り外される。図４は，保護部４が，流体吐出部材から取り外された様子を示す図である。流体吐出部２の露出部２１からは流体が吐出し，しかも，露出部２１は直接患者の肌に触れる可能性があるため，菌や汚れが付着しないように，密閉状態で保護することが好ましい。保護部４は，流体吐出部２の露出部２１に対応した大きさの溝部４１を有する。「露出部２１に対応した大きさ」とは，溝の深さ及び溝の直径が，露出部２１が隆起する高さ及び露出部２１の直径に対応しているという意味である。溝部４１の溝の深さは，露出部が隆起するものである場合に，その隆起した高さと略同一又はそれ以上であればよい。溝部４１の深さは、露出部２１の装填の際に不都合が生じず、保護部４を取り外す際に露出部２１に損傷を生じたりしないような十分な深さであることが好ましい。例えば、溝部４１の深さは、露出部の隆起した高さの2倍程度であることが好ましい。また、溝部４１の溝の直径は、同様の不都合や損傷が生じないように、露出部の直径と略同一又はそれ以上であればよい。例えば，溝部４１の溝の直径は，流体吐出部２の胴体の直径と等しいものであることが好ましい。また，溝部４１の形状の例は，円弧状又は多角形状に窪んだものである。流体吐出部２３が，円錐台形状に隆起したものである場合，これに対応して，溝部４１の形状は，円錐台形上に窪むように形成することとしてもよい。 (1-4. Protection part)
As shown in FIG. 1, the protection part 4 is provided to protect the exposed part 21 of the fluid discharge part 2 and is removed in use. FIG. 4 is a diagram illustrating a state where the protection unit 4 is detached from the fluid ejection member. Since the fluid is discharged from the exposed portion 21 of the fluid discharge portion 2 and the exposed portion 21 may directly touch the patient's skin, it is preferably protected in a sealed state so that bacteria and dirt are not attached. . The protection part 4 has a groove part 41 having a size corresponding to the exposed part 21 of the fluid discharge part 2. The “size corresponding to the exposed portion 21” means that the depth of the groove and the diameter of the groove correspond to the height at which the exposed portion 21 rises and the diameter of the exposed portion 21. When the exposed portion is raised, the depth of the groove of the groove portion 41 may be substantially the same as or higher than the raised height. The depth of the groove portion 41 is preferably a sufficient depth so that no inconvenience occurs when the exposed portion 21 is loaded and the exposed portion 21 is not damaged when the protective portion 4 is removed. For example, the depth of the groove portion 41 is preferably about twice the height of the exposed portion raised. Further, the groove diameter of the groove portion 41 may be substantially the same as or larger than the diameter of the exposed portion so that similar inconvenience and damage do not occur. For example, the diameter of the groove of the groove part 41 is preferably equal to the diameter of the body of the fluid discharge part 2. Moreover, the example of the shape of the groove part 41 is hollow in circular arc shape or polygonal shape. When the fluid discharge portion 23 is raised in a truncated cone shape, the groove portion 41 may be formed so as to be recessed on the truncated cone shape.
　図１に示すように，保護部４は，溝部４１を除き，その胴体を中実構造の円柱形状で形成することとしても良い。また，保持部３と連結された端部と逆側の端部を半球形状に形成することとしてもよい。保護部４は，図４に示すように，使用に際して取り外される。保護部４は，摘まんでねじ切るようにして取り外すことができることとしてもよい。また，保護部４は，保護部４の中心軸に対して，横方向から力を加えることで取り外すことができることとしてもよい。また，保護部４は，壁かい性により保持部３から取り外すことができることとしてもよい。保護部４は，このようにして流体吐出部材１００から取り外されるため，使用に際して取り外しを行い易いように，その胴体部を形成することが好ましい。例えば，溝部４１を除き，保護部４を中実構造とすることにより，取り外す際に胴体部が摘まれたとしても，保護部４の形状が変化することがなくなるため，摘む力を加え易くなる。また，保護部４の外壁表面に公知の滑り止め加工を施すこととしてもよい。また，保護部４の胴体の直径の例としては，１ｍｍ～５ｍｍ，２ｍｍ～４ｍｍ，又は３ｍｍ～３．５ｍｍがあげられる。 As shown in FIG. 1, the protection part 4 is good also as forming the cylinder body of the solid structure except the groove part 41. As shown in FIG. Moreover, it is good also as forming the edge part on the opposite side to the edge part connected with the holding | maintenance part 3 in hemispherical shape. As shown in FIG. 4, the protection unit 4 is removed during use. The protection part 4 is good also as being able to remove by screwing and screwing. Moreover, the protection part 4 is good also as being able to be removed by applying a force from the side with respect to the central axis of the protection part 4. Moreover, the protection part 4 is good also as being able to remove from the holding | maintenance part 3 by wall covering property. Since the protection part 4 is removed from the fluid ejection member 100 in this way, it is preferable to form the body part so that the protection part 4 can be easily removed in use. For example, by forming the protective part 4 in a solid structure except for the groove part 41, even if the body part is picked when removing, the shape of the protective part 4 will not change, so that it is easy to apply a picking force. . Moreover, it is good also as giving a well-known anti-slip process to the outer wall surface of the protection part 4. FIG. Examples of the diameter of the body of the protection unit 4 include 1 mm to 5 mm, 2 mm to 4 mm, or 3 mm to 3.5 mm.

The thickness of the connecting portion 5 is preferably thinner than the thickness of the holding portion 3 and the protective portion 4. Moreover, as shown in FIG. 1, the connection part 5 is formed by making a cut | interruption from the upper diagonal direction with respect to the outer peripheral wall of the protection part 4 in the location connected with the holding | maintenance part 3 among the protection parts 4. FIG. It is good as well. As described above, the thickness of the material forming the connecting portion 5 is smaller than the thickness of the material forming the holding portion 3 and the thickness of the material forming the protective portion 4. It becomes easy to remove from the part 3. Moreover, the connection part 5 may be formed by making a cut | interruption with respect to the inner peripheral wall of the protection part 4 which forms the groove part 41 of the protection part 4.

The angle of the connecting portion 5, that is, the angle between the upper surface of the holding portion 3 and the protective portion 4, and the angle between the cuts made from the upper oblique direction, is, for example, 10 degrees to 60 degrees, 20 degrees to 50 degrees, or 30 degrees. It may be up to 40 degrees. Moreover, when the force from a horizontal direction is applied with respect to the center axis | shaft of the protection part 4, the connection part 5 may be damaged by brittleness.
　保持部３と保護部４は，連結部５を介して，一体的に形成されていることが好ましい。保持部３と保護部４は，予め一体的に形成されているものであってもよい。また，保持部３と保護部４を別々に形成した後，例えば，溶接のような手段を用いて一体的に形成することとしてもよい。
（２．第２の実施の形態） It is preferable that the holding part 3 and the protection part 4 are integrally formed via the connecting part 5.

(2. Second Embodiment)
　図５は，本発明の第２の実施の形態に係る流体吐出部材２００の基本構成を示す概略図である。図５は，例えば経鼻投与装置（噴霧器）のような，容器本体内の流体を，広範囲に噴霧することを要する器具の容器本体内に取り付けられる流体吐出部材である。なお，本発明の第２の実施の形態についての説明において，前述の本発明の第１の実施の形態に関する説明と重複する箇所については，これを引用して，説明を省略する。 FIG. 5 is a schematic diagram showing a basic configuration of a fluid ejection member 200 according to the second embodiment of the present invention. FIG. 5 shows a fluid discharge member attached to a container body of an instrument that needs to spray a wide range of fluid in the container body, such as a nasal administration device (a sprayer). Note that in the description of the second embodiment of the present invention, portions overlapping with the description of the first embodiment of the present invention described above are cited and the description thereof is omitted.
　図５に示されるように，流体吐出部材２００は，流体吐出部２と，保持部３と，保護部４と，連結部５とを有する。流体吐出部２は，流体が収容される容器本体１から露出する露出部２１を有する。保持部３は，流体吐出部２の露出部２１が容器本体１から露出するように，流体吐出部２を，容器本体１内の一端部に保持する。保護部４は，流体吐出部２の露出部２に対応する大きさの溝部４１を有する。連結部５は，保護部４の溝部４１が，流体吐出部２の露出部２１を覆うように，保護部４と保持部３とを連結する。連結部５は，保持部３及び保護部４より，素材の厚みが薄くなっている。そして，保護部５に対して力を加えることで，連結部５が破損し，流体吐出部２の露出部２１が露出される。これにより，容器本体１から露出された流体吐出部２の露出部２１から，容器本体1内に収容される流体が，吐出するようになる。 As shown in FIG. 5, the fluid ejection member 200 includes a fluid ejection part 2, a holding part 3, a protection part 4, and a connection part 5. The fluid discharge part 2 has an exposed part 21 exposed from the container body 1 in which the fluid is accommodated. The holding part 3 holds the fluid discharge part 2 at one end in the container main body 1 so that the exposed part 21 of the fluid discharge part 2 is exposed from the container main body 1. The protection part 4 has a groove part 41 having a size corresponding to the exposed part 2 of the fluid discharge part 2. The connection part 5 connects the protection part 4 and the holding part 3 so that the groove part 41 of the protection part 4 covers the exposed part 21 of the fluid discharge part 2. The connecting portion 5 is made of a material thinner than the holding portion 3 and the protecting portion 4. Then, by applying a force to the protection part 5, the connection part 5 is broken and the exposed part 21 of the fluid discharge part 2 is exposed. Thereby, the fluid accommodated in the container main body 1 is discharged from the exposed portion 21 of the fluid discharge portion 2 exposed from the container main body 1.

FIG. 6 is a schematic diagram showing an assembly structure of the fluid ejection member 200 according to the second embodiment of the present invention. FIG. 6A shows a diagram in which the fluid discharge part 2 is fitted into a member (socket member) in which the holding part 3 and the protection part 4 are integrated by the connecting part 5. In other words, the fluid discharge member 200 shown in FIG. 6A is formed by fitting the fluid discharge member 2 shown in FIG. 6C from the bottom of the socket member shown in FIG. 6B. FIGS. 6 (a ′), (b ′), and (c ′) are bottom views of FIGS. 6 (a), (b), and (c), respectively.
（２－１．容器本体）
　流体吐出部材２００は，容器本体１の内部に取り付けられている。この，容器本体１は，例えば，経鼻投与装置に用いられるアンプルであってもよい。また，流体吐出部材２００が取り付けられた端部と反対側の端部が，流体を供給する供給源（例えば蛇口）と結合する筒状の部材であっても良い。 (2-1. Container body)
The fluid discharge member 200 is attached inside the container body 1. The container body 1 may be an ampoule used for a nasal administration device, for example. Moreover, the cylindrical member couple | bonded with the supply source (for example, faucet) which supplies the fluid may be sufficient as the edge part on the opposite side to the edge part to which the fluid discharge member 200 was attached.
（２－２．流体吐出部）
　流体吐出部２は，容器本体１内に充填される流体を吐出するための部材である。図５に示すように，流体吐出部２には，流体吐出部の中心軸に沿って，流路２２が貫通形成されている。図１に示す，第１の実施の形態と比較し，流路２２は，幅広に形成されている。貫通形成された流路２２は，その両端が開放端とされ，容器本体外側が流体吐出口２３となる。流体吐出口２３の直径は，０．０１ｍｍ～０．１５ｍｍ，０．１ｍｍ～０．３ｍｍ，０．１５ｍｍ～０．２５ｍｍ又は０．２ｍｍであってもよい。流路２２は，流体吐出部２の容器本体内側から流体吐出口２３側に進むにつれて先細となっている。また，流路２２の先細となる部分を延ばしてできた円錐形の頂角は，鈍角となっている。換言すると，貫通形成された流路２２の空間を延ばしてできた円錐形の頂角が，鈍角となっている。この円錐形の頂角は，例えば９０度～１７０度があげられ，好ましくは１００度～１６０あり，より好ましくは１１０度～１５０度である。このような角度であれば，流体を調整し，流路２２における流体の流通速度を遅くすることができ，流体をより広範囲に噴霧することができる。すなわち，薬剤を噴霧する噴霧器の場合であれば，より広範囲の患部に薬剤を塗布することができる。 (2-2. Fluid discharge part)
The fluid discharge unit 2 is a member for discharging the fluid filled in the container body 1. As shown in FIG. 5, a flow path 22 is formed through the fluid ejection unit 2 along the central axis of the fluid ejection unit. Compared to the first embodiment shown in FIG. 1, the flow path 22 is formed wider. The both ends of the channel 22 formed to be open are open ends, and the outer side of the container body is a fluid discharge port 23. The diameter of the fluid discharge port 23 may be 0.01 mm to 0.15 mm, 0.1 mm to 0.3 mm, 0.15 mm to 0.25 mm, or 0.2 mm. The flow path 22 tapers as it advances from the inside of the container main body of the fluid discharge part 2 to the fluid discharge port 23 side. The conical apex angle formed by extending the tapered portion of the flow path 22 is an obtuse angle. In other words, the conical apex angle formed by extending the space of the passage 22 formed so as to penetrate is an obtuse angle. The apex angle of this conical shape is, for example, 90 ° to 170 °, preferably 100 ° to 160 °, and more preferably 110 ° to 150 °. With such an angle, the fluid can be adjusted, the flow rate of the fluid in the flow path 22 can be reduced, and the fluid can be sprayed in a wider range. That is, in the case of a sprayer that sprays a medicine, the medicine can be applied to a wider range of affected areas.
　流体吐出部２は，容器本体１及び保持部３とは別の素材で形成される。流体吐出部２を形成する素材は，容器本体１及び保持部３を形成する素材と比較し，硬質な樹脂やガラスを用いて形成することが好ましい。 The fluid discharge part 2 is formed of a material different from that of the container body 1 and the holding part 3. The material forming the fluid discharge part 2 is preferably formed using a hard resin or glass as compared with the material forming the container body 1 and the holding part 3.
　また，図６（ａ'）及び図６（ｃ'）に示すように，流体吐出部２の流路２２には，その内壁に流体の流れの回転方向を制御するための回転溝２２ａを形成することとしてもよい。すなわち，流路２２に溝を設けることにより，流体はその溝に沿って流通することとなる。従って，流体を溝に沿って流通させることで，流路２２に侵入してきた流体を回転させるように流体の流れを変化させることができる。流路２２には，その内壁に，流体の進行方向に対して所定の角度傾斜した回転溝２２ａを複数形成することにより，流体の回転方向を制御してもよい。回転溝２２ａの傾斜の角度としては，例えば，５度～４５度，１０～４０度，１５度～３５度があげられる。また，流路２２は，その内壁に，螺旋状に旋回した回転溝を形成することにより，流体の回転方向を制御することとしてもよい。このような回転溝を設けることにより，流路を流通する流体を渦状に回転させることができる。渦状に回転した流体は，流体吐出口２３から吐出する際に，回転方向に広がるように，吐出されることとなるため，より広範囲に容器本体１内の流体を噴霧することができる。 Further, as shown in FIGS. 6 (a ′) and 6 (c ′), the flow path 22 of the fluid discharge section 2 is formed with a rotation groove 22a for controlling the rotation direction of the fluid flow on the inner wall thereof. It is good to do. That is, by providing a groove in the flow path 22, the fluid flows along the groove. Therefore, by flowing the fluid along the groove, the flow of the fluid can be changed so as to rotate the fluid that has entered the flow path 22. In the flow path 22, the rotation direction of the fluid may be controlled by forming a plurality of rotation grooves 22 a inclined on the inner wall at a predetermined angle with respect to the fluid traveling direction. Examples of the inclination angle of the rotating groove 22a include 5 to 45 degrees, 10 to 40 degrees, and 15 to 35 degrees. Moreover, the flow path 22 is good also as controlling the rotation direction of the fluid by forming in the inner wall the rotating groove swirled spirally. By providing such a rotating groove, the fluid flowing through the flow path can be rotated in a vortex. When the fluid rotated in a vortex is discharged from the fluid discharge port 23 so as to spread in the rotation direction, the fluid in the container body 1 can be sprayed in a wider range.

　図５に示すように，流体吐出部２は，容器本体１から露出する露出部２１を有する。本発明の第２の実施の形態においては，露出部２１は，流体吐出口２３を中心に，円錐台形状に窪んでいる。すなわち，流体吐出口２３から，流体が吐出される方向に向かうに連れて，幅広となっている。この円錐台形に窪む部分を延ばしてできた円錐形の頂角は，例えば９０度～１７０度があげられ，好ましくは１００度～１６０あり，より好ましくは１１０度～１５０度である。また，この円錐形の頂角は，流路２２の先細となる部分を延ばしてできた円錐形の頂角と等しいことが好ましい。露出部２１が，流体吐出口２３を中心に円錐台形状に窪んでいることにより，露出部２１の中心に位置する流体吐出口２３から，吐出される流体を，より広範囲に噴霧することができる。従って，流体吐出口２３から噴霧された薬剤を患部の広範囲に塗布することができる。[Correction 28.08.2012 under Rule 91]
As shown in FIG. 5, the fluid ejection part 2 has an exposed part 21 exposed from the container body 1. In the second embodiment of the present invention, the exposed portion 21 is recessed in a truncated cone shape around the fluid discharge port 23. That is, the width becomes wider from the fluid discharge port 23 in the direction in which the fluid is discharged. The apex angle of the conical shape formed by extending the recessed portion in the truncated cone shape is, for example, 90 ° to 170 °, preferably 100 ° to 160 °, more preferably 110 ° to 150 °. Further, it is preferable that the apex angle of the conical shape is equal to the apex angle of the conical shape formed by extending the tapered portion of the flow path 22. Since the exposed portion 21 is recessed in a truncated cone shape with the fluid discharge port 23 as the center, the fluid discharged from the fluid discharge port 23 located at the center of the exposed portion 21 can be sprayed in a wider range. . Therefore, the medicine sprayed from the fluid discharge port 23 can be applied over a wide range of the affected area.
　図７においては，本発明の第２の実施の形態に係る流体吐出部２から，容器本体内の流体が吐出する様子を示している。まず，図７（ａ）においては，流体の流通する流路２２が，流体吐出部２を形成する素材の厚みの分だけ，一部直線的となっている。従って，流路２２の内側壁に沿う形で流体吐出口２３に収束された流体が，最終的に一部直線的となった流路を流通することとなるため，流体は，流体吐出口２３から程度集中的に吐出される。また，図７（ｂ）においては，流体吐出口２３の形状が円錐台形状に窪むように形成されている。換言すると，流体吐出口２３の形状が，流体の進行方向に対して幅広となっている。このように，流体吐出口２３を形成する流体吐出部２２の素材に下斜め方向の切れ込みを入れることによって，流体吐出口２３から吐出された流体が散散して吐出（噴霧）しやすいようになっている。従って，流体吐出口２３から吐出する流体は，ある程度の広がりをもって吐出される。また，図７（ｃ）においては，流体吐出口２３を形成する流体吐出部２の素材に水平方向に切り込みが入れられ，流体吐出口２３が１８０度開かれたものとなっている。このように，流体吐出口２３は，流体吐出口２３から吐出される流体の広がりを遮るものがなくなるように形成されており，ここから吐出する流体を，より広く散散させることができる。このように，流体吐出口２３の形状を調整することにより，吐出する流体の状態を，流体吐出部材２００の用途に応じた所望の状態とすることができる。なお，このように，吐出口２３の形状が微細に異なるだけでも，吐出される流体の状態が大きく異なることとなる。従来のアンプルは，先端部を取り外すことで生ずる断面を吐出口として利用していたが，これでは先端部を取り外す際に，吐出口の形状が破損等により変化してしまうため，アンプルの用途に応じた所望の状態で流体を吐出することが困難であった。そこで，本発明に係る流体吐出部材２００のように，予め流路２２及び吐出口２３を精度よく形成しておき，それを保護部によって保護しておくことにより，常にアンプルの用途に応じた所望の状態で流体を吐出することができるように，流路２２及び吐出口２３の形状を維持しておくことができる。 FIG. 7 shows a state in which the fluid in the container body is discharged from the fluid discharge unit 2 according to the second embodiment of the present invention. First, in FIG. 7A, the flow path 22 through which the fluid flows is partially straight for the thickness of the material forming the fluid discharge portion 2. Accordingly, since the fluid converged on the fluid discharge port 23 along the inner wall of the flow channel 22 finally flows through the partially straight flow channel, the fluid flows into the fluid discharge port 23. It is discharged intensively from around. In FIG. 7B, the fluid discharge port 23 is formed in a truncated cone shape. In other words, the shape of the fluid discharge port 23 is wider with respect to the fluid traveling direction. In this way, by making a diagonal cut in the material of the fluid discharge portion 22 forming the fluid discharge port 23, the fluid discharged from the fluid discharge port 23 is scattered and easily discharged (sprayed). It has become. Therefore, the fluid discharged from the fluid discharge port 23 is discharged with a certain extent. Further, in FIG. 7C, the material of the fluid discharge part 2 forming the fluid discharge port 23 is cut in the horizontal direction, and the fluid discharge port 23 is opened 180 degrees. As described above, the fluid discharge port 23 is formed so as not to obstruct the spread of the fluid discharged from the fluid discharge port 23, and the fluid discharged therefrom can be more widely dispersed. Thus, by adjusting the shape of the fluid discharge port 23, the state of the fluid to be discharged can be set to a desired state according to the application of the fluid discharge member 200. As described above, even if the shape of the discharge port 23 is slightly different, the state of the fluid to be discharged is greatly different. Conventional ampules used the cross section produced by removing the tip as a discharge port. However, when the tip is removed, the shape of the discharge port changes due to breakage, etc. It was difficult to discharge the fluid in a desired state. Therefore, like the fluid discharge member 200 according to the present invention, the flow path 22 and the discharge port 23 are formed in advance with high accuracy, and are protected by the protection unit, so that a desired response according to the application of the ampoule can be obtained. The shape of the flow path 22 and the discharge port 23 can be maintained so that the fluid can be discharged in this state.
　図５において，流体吐出部２は，テーパー形状となっている。流体吐出部２は，テーパーとなっている斜辺部分を保持部３に押し付けるようにして，保持部３と結合している。また，流体吐出部２の容器本体内側の端部にフランジを設け，フランジを保持部３に押しつけるようにして，流体吐出部２と保持部３を結合させることとしてもよい。 In FIG. 5, the fluid ejection part 2 has a tapered shape. The fluid discharge unit 2 is coupled to the holding unit 3 such that a tapered oblique side portion is pressed against the holding unit 3. Alternatively, a flange may be provided at the inner end of the container body of the fluid discharge unit 2, and the fluid discharge unit 2 and the holding unit 3 may be coupled by pressing the flange against the holding unit 3.
（２－３．保持部）
　図５に示すように，保持部３は，流体吐出部２の露出部２１が，容器本体１から露出するように容器本体１内に保持する。容器本体１の開放端側の開放部は，保持部３の胴体部上部３２の直径と略同径の開放部とされており，この容器本体１の開放部に，保持部３の胴体上部３２が押し込まれるようにして嵌着される。また，保持部３の胴体上部３２が，容器本体２の開放部に押し込まれるようにして嵌着された際，保持部３の窪み部３３に，容器本体の突起部が嵌り込むようになっている。これにより，保持部３は，容器本体１内に取り付けられる。 (2-3. Holding part)
As shown in FIG. 5, the holding part 3 holds the exposed part 21 of the fluid discharge part 2 in the container body 1 so that the exposed part 21 is exposed from the container body 1. The open part on the open end side of the container body 1 is an open part having a diameter substantially the same as the diameter of the upper part 32 of the body part of the holding part 3, and the upper part 32 of the body part of the holding part 3 is connected to the open part of the container body 1. Is inserted and pushed. Further, when the body upper part 32 of the holding part 3 is fitted and pushed into the open part of the container main body 2, the protrusion of the container main body is fitted into the recess 33 of the holding part 3. Yes. Thereby, the holding | maintenance part 3 is attached in the container main body 1. FIG.
　保持部３の胴体部上部３２の上面は，接続部５を介して，保護部４と連結されている。保持部３と保護部４は，接続部を介して，一体的に形成されていることが好ましい。 The upper surface of the body part upper part 32 of the holding part 3 is connected to the protection part 4 through the connection part 5. It is preferable that the holding part 3 and the protection part 4 are integrally formed via the connection part.
（２－４．保護部）
　図５に示すように，保護部４は，流体吐出部２の露出部２１を保護するために設けられ，使用に際して取り外される。図８は，保護部４が流体吐出部材２００から取り外された様子を示している。流体吐出部２の露出部２１からは流体が吐出するため，露出部２２に菌や汚れが付着しないように，露出部２１を密閉状態で保護することが好ましい。保護部４は，流体吐出部２の露出部２１に対応した大きさの溝部４１を有する。本発明の第２の実施の形態において，露出部２１は突出するものではないため，溝部４１の溝の深さは，露出部２１に対応させる必要はない。例えば，溝部４１の深さは，０．５ｍｍ～２ｍｍ，０．５ｍｍ～１ｍｍであってもよい。また，溝部４１の溝の直径は，露出部２１の窪み部の直径と略同一又はそれ以上であればよい。溝部４１の形状の例は，円弧状又は多角形状に窪んだものである。 (2-4. Protection part)
As shown in FIG. 5, the protection part 4 is provided to protect the exposed part 21 of the fluid discharge part 2 and is removed during use. FIG. 8 shows a state where the protection unit 4 is detached from the fluid ejection member 200. Since fluid is discharged from the exposed portion 21 of the fluid discharge portion 2, it is preferable to protect the exposed portion 21 in a sealed state so that bacteria and dirt are not attached to the exposed portion 22. The protection part 4 has a groove part 41 having a size corresponding to the exposed part 21 of the fluid discharge part 2. In the second embodiment of the present invention, since the exposed portion 21 does not protrude, the groove depth of the groove portion 41 does not need to correspond to the exposed portion 21. For example, the depth of the groove 41 may be 0.5 mm to 2 mm, 0.5 mm to 1 mm. Further, the diameter of the groove of the groove portion 41 may be substantially the same as or larger than the diameter of the recessed portion of the exposed portion 21. The example of the shape of the groove part 41 is a thing dented in circular arc shape or polygonal shape.
　図５に示すように，保護部４は，溝部４１を除き，胴体を中実構造の円柱形状で形成しすることとしてもよい。また，保護部４は，保持部３と連結された端部と逆側の端部を半球形状に形成することとしてもよい。 As shown in FIG. 5, the protection part 4 may be formed of a solid cylindrical body except for the groove part 41. Moreover, the protection part 4 is good also as forming the edge part on the opposite side to the edge part connected with the holding | maintenance part 3 in a hemispherical shape.
（２－５．連結部）
　保持部３と保護部４は，保護部４の溝部４１が，流体吐出部２の露出部２１を覆うように，連結部５によって連結される。連結部５の厚みは，保持部３及び保護部４の厚みより，薄くなっている。 (2-5. Connection part)
The holding part 3 and the protection part 4 are connected by the connection part 5 so that the groove part 41 of the protection part 4 covers the exposed part 21 of the fluid discharge part 2. The thickness of the connecting portion 5 is thinner than the thickness of the holding portion 3 and the protective portion 4.
　保持部３と保護部４は，連結部５を介して，一体的に形成されていることが好ましい。保持部３と保護部４は，予め一体的に形成されているものであってもよい。また，保持部３と保護部４を別々に形成した後，例えば，溶接のような手段を用いて一体的に形成することとしても良い。 It is preferable that the holding part 3 and the protection part 4 are integrally formed via the connecting part 5. The holding part 3 and the protection part 4 may be integrally formed in advance. Moreover, after forming the holding | maintenance part 3 and the protection part 4 separately, it is good also as forming integrally using means, such as welding, for example.

（３．使用例）
　次に，本発明に係る流体吐出部材１００（又は２００，以下同じ）の使用例について説明する。
　図９は，本発明に係る流体吐出部材１００が容器本体（アンプル）１内に設けられた流体放出装置１０００を示す概略図である。図９（a）は，使用前の状態の流体放出装置を示し，図９（ｂ）は，使用の際の流体放出装置を示す。使用後の流体放出装置１０００の例は，無針注射器や噴霧器である。図９に示されるように，流体放出装置１０００は，アンプル１と，アンプル１内の端部に設置された流体吐出部材１００と，アンプル１内に設置された可動栓３００と，アンプル１内の可動栓３００がアンプル１内を進退するように可動させるピストン４００と，ピストン４００をアンプル１に保持するホルダー５００と，ホルダー５００によって固定されピストン４００を押下するに際して握られるグリップ６００を有する。[Correction 28.08.2012 under Rule 91]
(3. Usage example)
Next, a usage example of the fluid discharge member 100 (or 200, the same applies hereinafter) according to the present invention will be described.
FIG. 9 is a schematic view showing a fluid discharge device 1000 in which a fluid discharge member 100 according to the present invention is provided in a container body (ampoule) 1. FIG. 9 (a) shows the fluid discharge device in a state before use, and FIG. 9 (b) shows the fluid discharge device in use. Examples of the fluid discharge device 1000 after use are a needleless syringe and a sprayer. As shown in FIG. 9, the fluid discharge device 1000 includes an ampoule 1, a fluid discharge member 100 installed at an end of the ampoule 1, a movable plug 300 installed in the ampoule 1, and an ampoule 1. The movable stopper 300 has a piston 400 that moves so as to advance and retreat in the ampule 1, a holder 500 that holds the piston 400 in the ampule 1, and a grip 600 that is fixed by the holder 500 and is gripped when the piston 400 is pressed.
　アンプル１内に薬剤が収容された際，アンプル１，流体吐出部材１００及び可動栓３００は密閉系を構成する。このため，アンプル１，流体吐出部材１００及び可動栓３００は，薬剤を収容したアンプル容器として機能する。 When the drug is stored in the ampoule 1, the ampoule 1, the fluid discharge member 100 and the movable stopper 300 constitute a closed system. For this reason, the ampoule 1, the fluid discharge member 100, and the movable stopper 300 function as an ampoule container containing a medicine.
　図９に示されるように，ピストン４００は，支柱４０１と，支柱４０１と接続されたピストン台４０２とを有する。ピストン台４０２には，ばね部４０３が固定されている。支柱４０１の先端は，可動栓３００と接触する。そして，支柱４０１が移動すると，可動栓３００も連動して移動する。 As shown in FIG. 9, the piston 400 includes a support column 401 and a piston base 402 connected to the support column 401. A spring portion 403 is fixed to the piston base 402. The tip of the column 401 is in contact with the movable plug 300. And if the support | pillar 401 moves, the movable stopper 300 will also move interlockingly.
　図１０は，本発明に係る流体放出装置１０００に備えられたデフレクターブロック７００を示す図である。デフレクターブロック７００は，流体放出装置１０００の容器本体１内に，流体吐出部材２に近接又は密着して配置される。デフレクターブロック７００は，可動栓３００により圧力が負荷された容器本体内の流体を分流するための部材である。可動栓３００により押し出される流体は，デフレクターブロック７００の外周部に設けられた分流溝７１０に沿う形で分流され，分流溝７１０と容器本体の側壁に沿う形で流通し，流路２２に設けられた回転溝２３に沿って流体吐出口２３へと収束される。従って，分流された流体は，流体吐出部２の流路２２の急激な絞り込み（オリフィス）によって流体自体が互いに干渉し合うこととなり，流体吐出口２３から吐出する際に，噴霧状態となって外部へ吐出される。 FIG. 10 is a view showing a deflector block 700 provided in the fluid discharge device 1000 according to the present invention. The deflector block 700 is disposed in the container main body 1 of the fluid discharge device 1000 close to or in close contact with the fluid discharge member 2. The deflector block 700 is a member for diverting the fluid in the container body to which pressure is applied by the movable stopper 300. The fluid pushed out by the movable stopper 300 is diverted along a diverting groove 710 provided on the outer peripheral portion of the deflector block 700, circulates along the diverting groove 710 and the side wall of the container body, and is provided in the flow path 22. It converges to the fluid discharge port 23 along the rotating groove 23. Accordingly, the fluids separated from each other interfere with each other due to the rapid narrowing (orifice) of the flow path 22 of the fluid discharge unit 2, and when discharged from the fluid discharge port 23, the fluid becomes sprayed and externally Is discharged.

　図１１は，デフレクターブロック７００の構成の例を示す概略図である。図１１（ａ）は，デフレクターブロック７００の正面図を示し，図１１（ｂ）はデフレクターブロック７００の平面図を示している。また，図１１（ｃ）はデフレクターブロック７００の変形例を示している。デフレクターブロック７００は，ブロック本体の外周部に設けられた分流溝７１０と，一端に設けられた分流面７２０と，分流面７１０とは他端に設けられた緩衝部７３０を備える。デフレクターブロック７００は，分流面７２０を可動栓３００に対向させるように容器本体内に配置される。デフレクターブロック７００は，アンプル本体内に装填されて使用されるものであり，アンプル内の流体が分流溝７１０以外を流通することがないように，デフレクターブロック７００の外壁は，アンプルの内壁と同径若しくは略同径で形成される。アンプル内を満たす流体は，可動栓３００により押し出され，分流面７２０に沿って，ブロック本体の外壁に形成された分流溝７１０に流れ込む。分流溝７１０は，直線的に形成されており，分流溝７１０とアンプルの内側壁の間に流体の流路が形成される。デフレクターブロック７００は，可動栓３００と接触した場合であっても破損することのないように，比較的弾力性の富むシリコーン樹脂により形成することとしてもよい。また，図１１（ｃ）に示すように，デフレクターブロック７００は，分流溝７１０が，比較的幅広となっているものであってもよい。すなわち，デフレクターブロック７００のブロック本体の外周面の表面積において，分流溝７１０の面積が，分流溝７１００以外の面積よりも広く取られた形状であってもよい。このように，分流溝７１０を比較的幅広とすることによって，分流溝７１０とアンプルの内壁の間を流通する壁流の流れを良くすることができ，アンプル内を満たす流体を勢い良く噴霧させることができる。[Correction 28.08.2012 under Rule 91]
FIG. 11 is a schematic diagram illustrating an example of the configuration of the deflector block 700. FIG. 11A shows a front view of the deflector block 700, and FIG. 11B shows a plan view of the deflector block 700. FIG. 11C shows a modification of the deflector block 700. The deflector block 700 includes a diversion groove 710 provided on the outer periphery of the block main body, a diversion surface 720 provided at one end, and a buffer portion 730 provided at the other end of the diversion surface 710. The deflector block 700 is disposed in the container body so that the flow dividing surface 720 faces the movable stopper 300. The deflector block 700 is used by being loaded in the ampoule body, and the outer wall of the deflector block 700 has the same diameter as the inner wall of the ampoule so that the fluid in the ampoule does not flow through other than the diversion groove 710. Alternatively, they are formed with substantially the same diameter. The fluid filling the ampoule is pushed out by the movable plug 300 and flows along the flow dividing surface 720 into the flow dividing groove 710 formed on the outer wall of the block body. The diversion groove 710 is formed linearly, and a fluid flow path is formed between the diversion groove 710 and the inner wall of the ampoule. The deflector block 700 may be formed of a relatively elastic silicone resin so that the deflector block 700 is not damaged even when it comes into contact with the movable stopper 300. Moreover, as shown in FIG.11 (c), the deflector block 700 may have the diversion groove 710 comparatively wide. That is, in the surface area of the outer peripheral surface of the block main body of the deflector block 700, the shape of the diversion groove 710 may be larger than the area other than the diversion groove 7100. Thus, by making the diversion groove 710 relatively wide, the flow of the wall flow flowing between the diversion groove 710 and the inner wall of the ampoule can be improved, and the fluid filling the ampoule can be sprayed vigorously. Can do.
　また，デフレクターブロック７００は，分流面７２０とは逆側の端部に，緩衝部３２０を有する。ピストン４００の移動に連動して可動栓３００が移動した場合，可動栓３００は，デフレクターブロック７００の分流面７２０と接触する。このとき，ピストン４００の移動の勢いが速いと，可動栓３００がデフレクターブロック７００と接触した際に，デフレクターブロック７００を押し込み，デフレクターブロック７００の先にある，流体吐出部２を破損させてしまう可能性がある。そこで，流体吐出部２の破損を防止するために，デフレクターブロック７００の先端に緩衝部７２０を設け，デフレクターブロック７００が流体吐出部２と接触したときの衝撃を緩和させることが好ましい。緩衝部３２０は，例えば，比較的弾力性の富むシリコーン樹脂により形成することとしてもよい。また，緩衝部３２０は，他の可塑性を有する素材で形成することとしてもよい。また，緩衝部３２０は，可動栓本体３１０から一段のみ突起する形状であってもよいし，図１０において示すような２段突起する形状，又は３段以上突起する形状としてもよい。また，緩衝部３２０は，ブロック本体と一体形成され，可動栓本体３１０を延伸することにより形成することとしてもよい。可動栓３００によりデフレクターブロック７００が押し込まれ，緩衝部３２０が流体吐出部材２００の流体吐出部２と接触すると，緩衝部３２０は，形成された素材の弾力性又は可塑性により撓むこととなる。これにより，デフレクターブロック７００が強く押し込まれた場合であっても衝撃を緩和させることができる。 Further, the deflector block 700 has a buffer portion 320 at the end opposite to the flow dividing surface 720. When the movable stopper 300 moves in conjunction with the movement of the piston 400, the movable stopper 300 contacts the flow dividing surface 720 of the deflector block 700. At this time, if the momentum of the movement of the piston 400 is fast, the deflector block 700 is pushed in when the movable plug 300 comes into contact with the deflector block 700, and the fluid discharge unit 2 at the tip of the deflector block 700 may be damaged. There is sex. Therefore, in order to prevent the fluid discharge unit 2 from being damaged, it is preferable to provide a buffer unit 720 at the tip of the deflector block 700 so as to reduce the impact when the deflector block 700 contacts the fluid discharge unit 2. The buffer portion 320 may be formed of, for example, a silicone resin that is relatively elastic. Moreover, the buffer part 320 is good also as forming with the raw material which has another plasticity. Further, the buffer portion 320 may have a shape protruding from the movable stopper main body 310 only by one step, a shape protruding two steps as shown in FIG. 10, or a shape protruding three or more steps. In addition, the buffer 320 may be formed integrally with the block main body and formed by extending the movable plug main body 310. When the deflector block 700 is pushed in by the movable plug 300 and the buffer portion 320 comes into contact with the fluid discharge portion 2 of the fluid discharge member 200, the buffer portion 320 is bent due to the elasticity or plasticity of the formed material. Thereby, even if it is a case where the deflector block 700 is pushed in strongly, an impact can be relieved.

（３－１．使用方法）
　次に，本発明の流体放出装置の使用方法を説明する。すなわち，本発明は，上記した流体放出装置を用いた流体放出方法や，流体投与方法をも含む。[Correction 28.08.2012 under Rule 91]
(3-1. How to use)
Next, a method for using the fluid discharge device of the present invention will be described. That is, the present invention includes a fluid discharge method using the above-described fluid discharge device and a fluid administration method.
　先に説明したとおり，アンプル１，流体吐出部材２００及び可動栓３００は，流体を収容したアンプル容器として機能する。流体吐出部材２００が，アンプル１側に押し込まれないように，流体吐出部材２００の先端には保護部４が取り付けられているため，アンプル１内の流体は，アンプル外部に吐出することはない。 As described above, the ampoule 1, the fluid discharge member 200 and the movable stopper 300 function as an ampoule container containing a fluid. Since the protective portion 4 is attached to the tip of the fluid discharge member 200 so that the fluid discharge member 200 is not pushed into the ampoule 1 side, the fluid in the ampoule 1 is not discharged outside the ampoule.
　本発明の流体放出装置１０００は，例えば，樹脂又はガラスを用いて製造できる。また，例えば，アンプル１をガラスで製造し，それ以外の部分を樹脂で製造しても良い。また，バネを金属やセラミックスにより製造しても良い。形状の設計が終わった後は，各種金型や鋳型を用いて各要素を製造することにより，流体放出装置１０００を得ることができる。すなわち，公知の注射器やアンプルの製造方法を適宜修正することで，流体放出装置を製造できる。 The fluid discharge device 1000 of the present invention can be manufactured using, for example, resin or glass. Further, for example, the ampoule 1 may be made of glass and the other parts may be made of resin. Further, the spring may be made of metal or ceramics. After the design of the shape is completed, the fluid discharge device 1000 can be obtained by manufacturing each element using various molds and molds. That is, the fluid discharge device can be manufactured by appropriately modifying a known method for manufacturing a syringe or ampoule.
　流体放出装置１０００を使用する際には，流体吐出部材１００の保護部４を取り外される。すなわち，保護部４は，胴体部がねじ切るようにして取り外されることとしてもよいし，保護部４の中心軸に対し横方向からの力が加えられた際に壁かい性により取り外されることとしてもよい。本発明の流体吐出部材１００の場合，保護部４が取り外された面，すなわち連結部５が破損させられることによって生じた面が直接患者の皮膚に触れることはないため，取り外された面が完全に美麗なものである必要はない。保護部４が取り外されることにより，流体吐出部材１００の露出部２１が露出され，流路２２が開放される。 When using the fluid discharge device 1000, the protection part 4 of the fluid discharge member 100 is removed. In other words, the protection part 4 may be removed by screwing the body part, or when the force from the lateral direction is applied to the central axis of the protection part 4 due to wall covering. Also good. In the case of the fluid ejection member 100 of the present invention, the surface from which the protective portion 4 is removed, that is, the surface caused by damaging the connecting portion 5 does not directly touch the patient's skin. It doesn't have to be beautiful. By removing the protection part 4, the exposed part 21 of the fluid ejection member 100 is exposed and the flow path 22 is opened.

　そして，たとえば，中指と人差し指とをウイングに置き，親指をピストン台４０２に置き，ピストン台４０２を押すように親指に力を与えることで，可動栓３００に勢いが与えられる。すると，可動栓３００が移動する。可動栓３００が移動すると，アンプル１内に収容された流体が，流体吐出部材１００の流体吐出口２３から放出される。このようにして，流体が流体放出装置１０００から放出される。流体が流体放出装置１０００から放出される際に，一点に集中して放出されるか，又は比較的広範囲に噴霧されるかは，概ね，流体吐出部材１００の構造によって決まる。[Correction 28.08.2012 under Rule 91]
Then, for example, by placing the middle finger and the index finger on the wing, placing the thumb on the piston base 402, and applying force to the thumb so as to push the piston base 402, the movable plug 300 is given momentum. Then, the movable stopper 300 moves. When the movable stopper 300 moves, the fluid stored in the ampoule 1 is discharged from the fluid discharge port 23 of the fluid discharge member 100. In this way, the fluid is discharged from the fluid discharge device 1000. When the fluid is discharged from the fluid discharge device 1000, whether it is discharged in a concentrated manner or sprayed over a relatively wide range is largely determined by the structure of the fluid discharge member 100.
