Description
本発明は、医療の分野において点滴などで、薬液などの輸液を患者等に供給する輸液ラインに介設され、注射器などの接続具の先端のルアーテーパ部を差し込んで、輸液を供給する注入ポート構造に関する。 The present invention is an injection port structure for supplying an infusion by inserting a luer taper portion at the tip of a connection tool such as a syringe, which is interposed in an infusion line for supplying an infusion such as a medicinal solution to a patient or the like by drip in the medical field. About.
従来、点滴などの輸液ラインに介設される三方活栓などに設けられ、注射器などの接続具の先端のルアーテーパ部を差し込んで、薬液などの輸液を輸液ラインに供給するための注入口としての注入ポート（三方活栓のように輸液を混合させる場合には混注ポートともいう）が知られている（例えば、特許文献１参照）。 Conventionally, it is provided on a three-way stopcock, etc., intervened in an infusion line such as an infusion, and an injection as an injection port for supplying an infusion such as a medicinal solution to the infusion line by inserting a luer taper at the tip of a connector such as a syringe. A port (also referred to as a mixed injection port when an infusion solution is mixed like a three-way cock) is known (for example, see Patent Document 1).
特許文献１の三方活栓は、円筒状の基部と、基部からＴ字状に三方へ延出する導入管と導出管と注入ポートとを備えている。基部内には、一端にレバーを備える円柱状体が回動自在に挿設されている。円柱状体には、円柱状体を回動させることにより、導入管と導出管と注入ポートとを選択的に連通させる切換路が設けられている。 The three-way cock of Patent Document 1 includes a cylindrical base, an introduction pipe, a lead-out pipe, and an injection port extending from the base in three directions in a T shape. A cylindrical body having a lever at one end is rotatably inserted in the base. The cylindrical body is provided with a switching path for selectively communicating the introduction pipe, the outlet pipe, and the injection port by rotating the cylindrical body.
注入ポートは、一方が開口し他方が基部に接続される外筒部を備える。外筒部内には、外筒部の開口を閉塞する弾性弁が設けられている。弾性弁は、外筒部の外交を閉塞する弁本体部と、弁本体部の基部側に連設され、弁本体部がルアーテーパ部で中に押し込まれた後、ルアーテーパ部が外筒部から引き抜かれたときに、弁本体部を元の位置に押し戻すように復元力を作用させる筒状部とで構成される。 The injection port includes an outer cylinder part that is open at one end and connected to the base at the other end. An elastic valve for closing the opening of the outer cylinder part is provided in the outer cylinder part. The elastic valve is connected to the valve body part that closes the diplomacy of the outer cylinder part and the base side of the valve body part. After the valve body part is pushed in by the luer taper part, the luer taper part is pulled from the outer cylinder part. It is comprised with the cylindrical part which applies a restoring force so that a valve main-body part may be pushed back to an original position when it is extracted.
従来の注入ポートでは、接続具のルアーテーパ部が挿入されて、ルアーテーパ部に押された可撓性を有する弾性弁が内側に撓むことにより、輸液が流れる流路を狭めてしまう場合がある。また逆に、弾性弁が外側に（流路を広げる方向に）撓む場合であっても、ルアーテーパ部と注入ポートの輸液ラインと連通する連通孔との間に、拡径する部分が介在することとなり、この拡径した部分で輸液の流れが一旦広がりその後に連通孔でまた狭まるため、輸液が渦を巻くように流れて滞留する場合があり、輸液の注入抵抗が強まる場合がある。 In the conventional injection port, the luer taper portion of the connector is inserted, and the flexible elastic valve pushed by the luer taper portion bends inward, which may narrow the flow path through which the infusion solution flows. On the other hand, even when the elastic valve is bent outward (in the direction of expanding the flow path), a diameter-expanding portion is interposed between the Luer taper portion and the communication hole communicating with the infusion line of the injection port. In other words, since the flow of the infusion once spreads in the expanded portion and then narrows again in the communication hole, the infusion may flow and stay in a vortex, which may increase the infusion resistance of the infusion.
本発明は、注射器などの接続具の先端のルアーテーパ部を差し込んで、輸液を輸液ラインに供給するときの注入抵抗を従来よりも低く抑えることができる注入ポート構造を提供することを目的とする。 An object of the present invention is to provide an injection port structure in which a luer taper portion at the tip of a connection tool such as a syringe can be inserted to suppress injection resistance when supplying an infusion solution to an infusion line.
上記目的を達成するため、本発明は、医療用の輸液ラインに設けられ、接続具の先端のルアーテーパ部が差し込まれることにより開口される可撓性を有する弾性弁を備える注入ポートであって、一方が開口し他方が輸液ラインに接続される外筒部を備え、前記弾性弁は、前記外筒部の開口を閉塞するように前記外筒部内に配置され、該弾性弁には、前記注入ポートに接続される接続具のルアーテーパ部が前記外筒部の開口から挿入されたときに、前記弾性弁による前記外筒部の閉塞が解除して開口されるように切り込まれた切込部が設けられ、前記外筒部内には、内筒部が設けられ、前記内筒部の先端は、前記弾性弁を押し退けて挿入された前記ルアーテーパ部の先端と直接接触して、輸液が前記ルアーテーパ部内から直接流れ込むことを特徴とする。 In order to achieve the above object, the present invention is an injection port provided with a flexible elastic valve provided in a medical infusion line and opened by inserting a luer taper portion at the tip of a connector, An outer cylinder part having one opening and the other connected to an infusion line is provided, and the elastic valve is disposed in the outer cylinder part so as to close the opening of the outer cylinder part. When the luer taper part of the connection tool connected to the port is inserted from the opening of the outer cylinder part, the notch part cut so as to be opened by releasing the blockage of the outer cylinder part by the elastic valve An inner tube portion is provided in the outer tube portion, and a tip of the inner tube portion is in direct contact with a tip of the luer taper portion inserted by pushing away the elastic valve, so that the infusion is transferred to the luer taper. Features and son-in-law directly flow into the portion To.
従来の注入ポートでは、接続具のルアーテーパ部が挿入されて、ルアーテーパ部に押された可撓性を有する弾性弁が内側に撓むことにより、輸液が流れる流路を狭めてしまう場合がある。また逆に、弾性弁が外側に（流路を広げる方向に）撓む場合であっても、ルアーテーパ部と注入ポートの輸液ラインと連通する連通孔との間に、拡径する部分が介在することとなり、この拡径した部分で輸液の流れが一旦広がりその後に連通孔でまた狭まるため、輸液が渦を巻くように流れて滞留する場合があり、輸液の注入抵抗が強まる場合がある。 In the conventional injection port, the luer taper portion of the connector is inserted, and the flexible elastic valve pushed by the luer taper portion bends inward, which may narrow the flow path through which the infusion solution flows. On the other hand, even when the elastic valve is bent outward (in the direction of expanding the flow path), a diameter-expanding portion is interposed between the Luer taper portion and the communication hole communicating with the infusion line of the injection port. In other words, since the flow of the infusion once spreads in the expanded portion and then narrows again in the communication hole, the infusion may flow and stay in a vortex, which may increase the infusion resistance of the infusion.
本発明によれば、注入ポートに挿入された接続具のルアーテーパ部の先端は、内筒部の先端と接触し、ルアーテーパ部から注入される輸液は、直接内筒部内に供給されて輸液ラインへと流れる。従って、本発明の注入ポート構造によれば、従来の注入ポートのように、輸液の注入抵抗が高まる虞がなく、輸液の注入抵抗を抑えることができる。 According to the present invention, the tip of the luer taper portion of the connector inserted into the injection port is in contact with the tip of the inner cylinder portion, and the infusion fluid injected from the luer taper portion is directly supplied into the inner cylinder portion to the infusion line. And flow. Therefore, according to the injection port structure of the present invention, unlike the conventional injection port, there is no possibility that the injection resistance of the infusion solution is increased, and the injection resistance of the infusion solution can be suppressed.
また、本発明の注入ポートは、輸液ラインに介設される三方活栓に混注ポートとして設けてもよい。 Moreover, you may provide the injection | pouring port of this invention as a mixed injection port in the three-way cock inserted in the infusion line.
図１から図４を参照して、本発明の注入ポート構造を適用した三方活栓の実施形態を説明する。図１及び図３に示すように、本実施形態の三方活栓１は、注射器等の接続具２の先端に設けられた雄型のルアーテーパ部３が挿入される注入ポート４を備える。 An embodiment of a three-way stopcock to which the injection port structure of the present invention is applied will be described with reference to FIGS. As shown in FIG.1 and FIG.3, the three-way cock 1 of this embodiment is equipped with the injection | pouring port 4 in which the male type luer taper part 3 provided in the front-end | tip of the connection tools 2, such as a syringe, is inserted.
図１を参照して、三方活栓１は、点滴などで薬液などの輸液を患者等に供給する医療用の輸液ラインに介設されるものである。三方活栓１は、円筒状の基部５と、基部５からＴ字状に三方へ延出する導入管６と導出管７と注入ポート４（混注ポート）とを備えている。導入管６と導出管７とは、基部５を介して互いに同軸線上に延設され、注入ポート４は、基部５を介して導入管６及び導出管７の軸線に対して直交する軸線上に延設されている。 Referring to FIG. 1, a three-way stopcock 1 is interposed in a medical infusion line that supplies an infusion such as a medicinal solution to a patient or the like by drip or the like. The three-way cock 1 includes a cylindrical base 5, an introduction pipe 6, a lead-out pipe 7, and an injection port 4 (mixed injection port) extending from the base 5 in a T shape in three directions. The introduction pipe 6 and the outlet pipe 7 are extended on the same axis via the base 5, and the injection port 4 is on an axis orthogonal to the axis of the inlet pipe 6 and the outlet pipe 7 via the base 5. It is extended.
基部５内には、上部にＴ字状のレバー（図示省略）を備える円柱状体８が液密かつ回動自在に挿設されている。円柱状体８には、Ｔ字状の切換路８ａが形成されている。 A cylindrical body 8 having a T-shaped lever (not shown) at the top is inserted in the base 5 in a liquid-tight and rotatable manner. The cylindrical body 8 is formed with a T-shaped switching path 8a.
切換路８ａは、レバー操作に伴う円柱状体８の回動によって、導入管６と注入ポート４と導出管７との何れかを選択的に連通させることができる。また、切換路８ａは、レバー操作に伴う円柱状体８の回動によって、導入管６と注入ポート４と導出管７との全てを連通させることもできる。 The switching path 8a can selectively communicate any one of the introduction pipe 6, the injection port 4, and the outlet pipe 7 by the rotation of the cylindrical body 8 accompanying the lever operation. The switching path 8a can also connect all of the introduction pipe 6, the injection port 4, and the outlet pipe 7 by the rotation of the cylindrical body 8 accompanying the lever operation.
注入ポート４は、外筒部９を備える。外筒部９は、基部５と一体に設けられた外筒基部９ａと、外筒基部９ａの先端部に設けられるキャップ部９ｂとで構成される。キャップ部９ｂの先端には、ルアーテーパ部３を受け入れ可能な開口が形成されている。 The injection port 4 includes an outer cylinder portion 9. The outer cylinder part 9 is comprised by the outer cylinder base part 9a provided integrally with the base 5, and the cap part 9b provided in the front-end | tip part of the outer cylinder base part 9a. An opening capable of receiving the luer taper portion 3 is formed at the tip of the cap portion 9b.
外筒部９内には、外筒基部９ａとキャップ部９ｂとに挟まれるようにして、ゴム等の可撓性を有する弾性体で略筒状に形成され先端に閉塞部を備える弾性弁１０が設けられている。弾性弁１０は、注入ポート４の先端（一方）で開口する部分を閉塞する弁本体部１１と、弁本体部１１の基部５側に連設し、弁本体部１１がルアーテーパ部３で中に押し込まれた後、ルアーテーパ部３が外筒部９から引き抜かれたときに、弁本体部１１を元の位置に押し戻すように復元力を作用させる筒状部１２とで構成される。弁本体部１１内には、基部５に接続される内筒部１４が設けられている。内筒部１４と基部５とは連通孔１５を介して輸液が流れるように連通している。 An elastic valve 10 is formed in a substantially cylindrical shape with a flexible elastic body such as rubber so as to be sandwiched between the outer cylinder base portion 9a and the cap portion 9b. Is provided. The elastic valve 10 is connected to the valve body portion 11 that closes the opening portion at the tip (one) of the injection port 4 and the base portion 5 side of the valve body portion 11, and the valve body portion 11 is located inside the luer taper portion 3. After being pushed in, when the luer taper part 3 is pulled out from the outer cylinder part 9, it is composed of a cylindrical part 12 that applies a restoring force so as to push the valve body part 11 back to its original position. Inside the valve main body 11, an inner cylinder portion 14 connected to the base portion 5 is provided. The inner cylinder portion 14 and the base portion 5 communicate with each other through the communication hole 15 so that the infusion solution flows.
弁本体部１１の中央には、切込部１３が設けられ、通常時は閉塞している。注入ポート４に注射器等の接続具２の先端のルアーテーパ部３が挿入されると、ルアーテーパ部３の先端で弁本体部１１が注入ポート４の内側に押し込まれて切込部１３が開口する。そして、ルアーテーパ部３の先端が弁本体部１１内を通過して内筒部１４の先端に直接当接する。これにより、注射器等の薬液（輸液）が注入ポート４から輸液ラインに介設される三方活栓１に供給される。 A notch 13 is provided in the center of the valve body 11 and is normally closed. When the luer taper part 3 at the tip of the connector 2 such as a syringe is inserted into the injection port 4, the valve body 11 is pushed into the injection port 4 at the tip of the luer taper part 3 and the notch part 13 is opened. Then, the tip of the luer taper portion 3 passes through the valve body portion 11 and directly contacts the tip of the inner cylinder portion 14. Thereby, a chemical solution (infusion solution) such as a syringe is supplied from the injection port 4 to the three-way cock 1 interposed in the infusion line.
次に、第１実施形態の三方活栓１の作動について説明する。まず、円柱状体８の切換路８ａが導入管６と注入ポート４と導出管７とに連通した全通状態のとき、例えば、導入管６から点滴等の薬液が導入され、注入ポート４には注射器等が接続されて他の薬液が注入され、それらの混合薬液が導出管７から送り出される。 Next, the operation of the three-way cock 1 of the first embodiment will be described. First, when the switching path 8a of the cylindrical body 8 is in a full communication state with the introduction pipe 6, the injection port 4 and the outlet pipe 7, for example, a chemical solution such as an infusion is introduced from the introduction pipe 6 into the injection port 4. Is connected to a syringe or the like to inject other chemicals, and the mixed chemicals are sent out from the outlet tube 7.
この全通状態から、レバー操作によって、円柱状体８を１８０°回転させると、円柱状体８の外周面により注入ポート４が閉鎖され、導入管６及び導出管７は切換路８ａにより連通した直線状連通状態となる。これにより、導入管６から導入された点滴等の薬液が、切換路８ａを通過して導出管７から導出される。 When the columnar body 8 is rotated by 180 ° from this full state by lever operation, the injection port 4 is closed by the outer peripheral surface of the columnar body 8, and the introduction pipe 6 and the outlet pipe 7 are communicated by the switching path 8a. A linear communication state is established. Thereby, the chemical solution such as the drip introduced from the introduction pipe 6 passes through the switching path 8a and is led out from the lead-out pipe 7.
また、図１に示す状態から、レバー操作によって、円柱状体８を反時計回りに９０°回転させると、円柱状体８の外周面により導入管６が閉鎖され、注入ポート４及び導出管７は切換路８ａにより連通したＬ字状連通状態となる。 In addition, when the cylindrical body 8 is rotated 90 ° counterclockwise by lever operation from the state shown in FIG. 1, the inlet pipe 6 is closed by the outer peripheral surface of the cylindrical body 8, and the injection port 4 and the outlet pipe 7. Is in an L-shaped communication state communicated by the switching path 8a.
また、切換路８ａは、その３つの開口が、レバーを導入管６と注入ポート４と導出管７とに対して斜めとなる位置に回転させたときに、導入管６と注入ポート４と導出管７との何れにも連通せずに基部５の内周面で閉塞されるように形成されている。これにより、レバーを斜めにするだけで導出管７からの薬液の供給を阻止することができ、利便性を維持させることができる。 Further, the switching path 8a has its three openings led out from the introduction pipe 6 and the injection port 4 when the lever is rotated to a position inclined with respect to the introduction pipe 6, the injection port 4 and the outlet pipe 7. It is formed so as to be blocked by the inner peripheral surface of the base portion 5 without communicating with any of the pipes 7. Thereby, supply of the chemical | medical solution from the derivation | leading-out pipe | tube 7 can be prevented only by making a lever diagonal, and the convenience can be maintained.
本実施形態の三方活栓１によれば、注入ポート４に差し込まれた接続具２の先端のルアーテーパ部３は、弾性弁１０の弁本体部１１を押し退けるようにして筒状部１２内を通過し、内筒部１４の先端と直接接触する。そして、ルアーテーパ部３から注入される輸液は、内筒部１４内に直接供給されて基部５と導出管７とを介して、三方活栓１が介設される輸液ライン（図示省略）へと流れる。従って、従来の注入ポートのように、輸液の注入抵抗が高まる虞がなく、輸液の注入抵抗を抑えることができる。 According to the three-way cock 1 of the present embodiment, the luer taper portion 3 at the tip of the connector 2 inserted into the injection port 4 passes through the cylindrical portion 12 so as to push away the valve main body portion 11 of the elastic valve 10. In direct contact with the tip of the inner cylinder portion 14. Then, the infusion injected from the luer taper part 3 is directly supplied into the inner cylinder part 14 and flows through the base part 5 and the outlet pipe 7 to an infusion line (not shown) in which the three-way cock 1 is interposed. . Therefore, unlike the conventional injection port, there is no possibility that the injection resistance of the infusion solution will increase, and the injection resistance of the infusion solution can be suppressed.
図５及び図６は従来の注入ポート４’を備える三方活栓１’を示したものである。 5 and 6 show a three-way cock 1 'having a conventional injection port 4'.
従来の三方活栓１’では、接続具２のルアーテーパ部３が挿入されて、ルアーテーパ部３に押された可撓性を有する弾性弁１０が内側に撓むことにより、輸液が流れる流路を狭めてしまう場合がある。また逆に、弾性弁１０が外側に（流路を広げる方向に）撓む場合であっても、ルアーテーパ部３と三方活栓１’の輸液ラインと連通する連通孔１５との間に、拡径する部分が介在することとなり、この拡径した部分で輸液の流れが一旦広がりその後に連通孔１５でまた狭まるため、輸液が渦を巻くように流れて滞留する場合があり、輸液の注入抵抗が強まる虞がある。 In the conventional three-way stopcock 1 ', the luer taper portion 3 of the connector 2 is inserted, and the flexible elastic valve 10 pushed by the luer taper portion 3 bends inward, thereby narrowing the flow path through which the infusion solution flows. May end up. Conversely, even when the elastic valve 10 is bent outward (in the direction of expanding the flow path), the diameter of the elastic valve 10 is increased between the Luer taper portion 3 and the communication hole 15 communicating with the infusion line of the three-way cock 1 ′. The flow of the infusion once spreads in the enlarged diameter portion and then narrows again in the communication hole 15, so that the infusion may flow and stay like a vortex, and the infusion resistance of the infusion is reduced. There is a risk of strengthening.
なお、本実施形態においては、本発明の注入ポート構造を三方活栓１に適用したものを用いて説明したが、本発明の注入ポート構造は、これに限らず、例えば、輸液ラインの端部に本発明の注入ポートを設けてもよい。これによっても、本発明の注入抵抗の低減という作用効果を奏することができる。 In addition, in this embodiment, although demonstrated using what applied the injection | pouring port structure of this invention to the three-way cock 1, the injection | pouring port structure of this invention is not restricted to this, For example, in the edge part of an infusion line The injection port of the present invention may be provided. This also has the effect of reducing the injection resistance of the present invention.
