発明が解決しょうとする課題 Problems to be solved by the invention
[0003] しかしながら、 シリンジに充填された薬液の注入後は、 シリンジ内部のピ ストンを押す薬液注入装置のプレッサーの一部がシリンジの内部に残存する こととなり、 シリンジをプレッサーに対して垂直に取り外そうとすると、 こ
のプレッサーがシリンジに引っ掛かってしまう。 このため、 従来は、 薬液の 注入を終えてシリンジをシリンジホルダーから取り外す場合、 シリンジのシ リンジホルダーからの取り外しに先立って、 シリンジの内部に存する薬液注 入装置のプレッサーをシリンジの外部に引き出していた。 [0003] However, after the injection of the chemical solution filled in the syringe, a part of the presser of the chemical injection device that pushes the piston inside the syringe remains inside the syringe, and the syringe is taken perpendicular to the presser. If you try to remove it, The presser gets caught in the syringe. For this reason, conventionally, when the injection of the chemical solution is completed and the syringe is removed from the syringe holder, the presser of the chemical injection device existing inside the syringe is pulled out of the syringe prior to the removal of the syringe from the syringe holder. It was.
そこで、 本発明は、 シリンジの内部に存する薬液注入装置のプレッサーを シリンジの外部に引き出さずとも、 シリンジをシリンジホルダーからの取り 外すことが可能なシリンジホルダー、 薬液注入装置、 及び薬液注入装置の制 御方法を提供することを目的とする。 Accordingly, the present invention provides a syringe holder, a chemical solution injection device, and a chemical solution injection device capable of removing the syringe from the syringe holder without pulling out the presser of the chemical solution injection device existing inside the syringe to the outside of the syringe. The purpose is to provide a method.
課題を解決するための手段 Means for solving the problem
[0004] 本発明によれば、 上記課題は、 次の手段により解決される。 [0004] According to the present invention, the above problem is solved by the following means.
[0005] 第 1の発明は、 広がることによりシリンジの保持を解除可能なシリンジ保 持部を備えたことを特徴とするシリンジホルダーである。 [0005] A first invention is a syringe holder including a syringe holding portion that can release the holding of the syringe by spreading.
従来は、 シリンジ保持部の形状が変化することがなく、 シリンジを薬液注 入装置のプレッサーに対して垂直に持ち上げていたが、 第 1の発明によれば 、 シリンジを保持しているシリンジ保持部が広がるため、 シリンジ保持部に よるシリンジの保持力を緩めたり、 あるいは、 シリンジの平行移動を妨げて いた部材をシリンジの外縁に向けて移動させてシリンジの平行移動の邪魔に ならない配置としたりできるため、 シリンジを薬液注入装置のプレッサーに 対して平行に移動させることが可能となる。 Conventionally, the shape of the syringe holding part does not change, and the syringe is lifted vertically with respect to the presser of the chemical injection device, but according to the first invention, the syringe holding part holding the syringe Therefore, it is possible to loosen the holding force of the syringe by the syringe holding part, or move the member that hindered the parallel movement of the syringe toward the outer edge of the syringe so that it does not interfere with the parallel movement of the syringe. Therefore, the syringe can be moved in parallel with the presser of the chemical liquid injector.
なお、 シリンジ保持部が 「広がる」 とは、 シリンジ保持部の一部分又は全 部が、 シリンジからシリンジホルダーの外縁の方向に移動することをいうが 、 その移動の方向成分に、 シリンジからシリンジホルダーの外縁に向けた成 分が含まれていれば足りる。 シリンジ保持部が広がれば、 シリンジ保持部の 一部分又は全部がシリンジからシリンジホルダーの外縁の方向に移動するた め、 シリンジ保持部によるシリンジの保持力が緩まったり、 あるいは、 シリ ンジの平行移動を妨げていた部材がシリンジの外縁に向けて移動しシリンジ の平行移動の邪魔にならない配置になつたリなどする。 “Syringe holding part spreads” means that part or all of the syringe holding part moves from the syringe toward the outer edge of the syringe holder. It only needs to have a component towards the outer edge. If the syringe holding part expands, part or all of the syringe holding part moves from the syringe toward the outer edge of the syringe holder, so that the holding power of the syringe by the syringe holding part is relaxed or the parallel movement of the syringe is hindered. The previously moved member moves toward the outer edge of the syringe and is placed so that it does not interfere with the parallel movement of the syringe.
[0006] 第 2の発明は、 前記シリンジ保持部は、 シリンジの保持を可能とする複数
のシリンジ保持手段を具備し、 前記複数のシリンジ保持手段のうちの少なく とも 1つが外側に移動することによりシリンジの保持が解除可能である、 こ とを特徴とする第 1の発明に係るシリンジホルダーである。 [0006] In a second aspect of the invention, the syringe holding unit includes a plurality of syringes that can hold the syringe. The syringe holder according to the first invention, characterized in that the syringe holding means can be released when at least one of the plurality of syringe holding means moves outward. It is.
第 2の発明によれば、 一体となったシリンジ保持部を広げなくとも、 複数 のシリンジ保持手段のそれぞれを外側に向けて移動させれば、 シリンジの保 持が解除されるため、 シリンジホルダーの構成を簡素化することができる。 なお、 シリンジ保持手段が 「外側に移動する」 とは、 シリンジ保持手段が、 シリンジからシリンジホルダーの外縁の方向に向けて移動することをいうが 、 その移動の方向成分に、 シリンジからシリンジホルダーの外縁に向けた成 分が含まれていれば足りる。 According to the second invention, since the holding of the syringe is released by moving each of the plurality of syringe holding means toward the outside without expanding the integrated syringe holding portion, the syringe holder The configuration can be simplified. The syringe holding means “moves outward” means that the syringe holding means moves from the syringe toward the outer edge of the syringe holder, and the direction component of the movement includes the syringe to the syringe holder. It only needs to have a component towards the outer edge.

To do. When the first gear 1 1 0 rotates, the fourth opening 1 7 1, the fifth opening 1 7 2, and the sixth opening 1 7 3 provided in the first gear 1 1 0 The first shuff rod 1 4 2, the third shuff rod 1 5 2, the fifth shuff rod 1 6 2, which penetrates, are connected to the fourth opening 1 7 1 in the first gear 1 70, respectively. The fifth opening 1 7 2 and the sixth opening 1 7 3 move from one end to the other end. However, the first shuffle シ ャ 1 4 2, the third shuff 5 1 5 2, and the fifth shuff 卜 1 6 2 are respectively the first opening 1 1 1 of the play 卜 1 1 0, The second opening 1 1 2, and the third opening 1 1 3, and in the plate 1 1 0, the first opening 1 1 1, the second opening 1 1 2, And it can only move within the third opening 1 1 3. Therefore, the areas where the first shaft 1 4 2, the third shaft 1 5 2, and the fifth shaft 1 6 2 can move are respectively the first opening 1 1 1 of the plate 1 1 0, 2nd opening 1 1 2, 3rd opening 1 1 3, 4th opening 1 7 1 of 1st gear 1 70, 5th opening 1 7 2, 6th opening Part 1 7 3 is the overlapping area. Thus, in the syringe holder 100 according to the embodiment of the present invention, the movement of the first shuffle rod 1 4 2, the third shuffle rod 1 5 2, and the fifth shuff rod 1 6 2 is performed. A fourth opening 1 71, a fifth opening 1 7 2, and a sixth opening 1 7 3 provided in the first gear 1 70, The first opening 1 1 1, the second opening 1 1 2, and the third opening 1 1 3 of the glance 1 1 10 are constrained. Thus, in the syringe holder 100 according to the present embodiment, the first shuffle rod 14 2, the third shuffle rod 15 2, and the fifth shaft 16 2 are connected to the outside of the syringe holder 100. The first syringe holding means 14 0, the second syringe holding means 15 0, and the third syringe holding means 16 0, to which these shuffle rods are respectively attached, are also provided. Further, it can be easily moved outside the syringe holder 100. Therefore, according to the syringe holder 100 according to the embodiment of the present invention, the holding of the flange portion 301 of the syringe 300 can be easily opened by a simple mechanism, and the syringe 300 is connected to the syringe holder 1. A mechanism for detaching toward the front of 0 0 (direction perpendicular to the plate 1 1 0) can be simply realized. As with the syringe holder 100 according to the present embodiment, the second shaft 14 3, the fourth shaft 15 3, and the sixth shaft 1 63 are connected to the first syringe. When the first gear 1 70 is rotated by being attached to the holding means 1 4 0, the second syringe holding means 1 5 0, and the third syringe holding means 1 60, the plate 1 1 If the first opening 1 1 1, the second opening 1 1 2, and the third opening 1 1 3 at 0 are movable in the first syringe holding means 1 4 0, 2nd The movement of the syringe holding means 150 and the third syringe holding means 160 can be stabilized.
また、 第 2のギア 1 9 0に凹凸を設けて、 これをセンサー 2 0 0で検出す ることとすれば、 第 2のギア 1 9 0の回転数を取得することができ、 レバー 1 8 0が引かれてシリンジ 3 0 0がシリンジホルダー 1 0 0から取り外し可 能であるか、 レバー 1 8 0が元の位置に戻ってシリンジ 3 0 0がシリンジホ ルダー 1 0 0に保持される状態である否かを判断可能となる。 このセンサー 2 0 0により、 第 2のギア 1 9 0の回転数が一定数に達した場合に、 薬液注 入装置 4 0 0のプレッサー 4 0 1を駆動させることとすれば、 シリンジホル ダー 1 0 0へのシリンジの取り付けの有無に応じて、 シリンジのピストン （ 図示せず） などを制御可能となり、 薬液注入における安全性などを向上させ
