Description

本考案は、患者による自己注射を行うためのオートインジェクタやスタンプ型の注射器の使用を補助する注入補助具に関するものである。 The present invention relates to an infusion aid that assists the use of an auto-injector or stamp-type syringe for self-injection by a patient.

従来、オートインジェクタやスタンプ型の注射器に装着して、注射部位に押し当てることで注射器の内部の針先を突出させ、注射部位に穿刺することで薬剤の注入を確実に行うように補助する注入補助具が提案されている。 Conventionally, it is attached to an auto-injector or a stamp-type syringe, and by pressing it against the injection site, the needle tip inside the syringe is projected, and by puncturing the injection site, injection that assists in injecting the drug is performed. Auxiliary tools have been proposed.

例えば、特許文献１において、注入補助具を注射器本体の先端側に差し込むとともに、薬剤注入の確認窓に係合させて装着するものが開示されている。 For example, Patent Document 1 discloses an injection assisting tool that is inserted into the tip end side of a syringe body and engaged with a confirmation window for drug injection.

しかしながら、上述した注入補助具は、注射器の針側の先端に装着するために、注射器本体の薬剤注入の確認窓に突起を係合させて簡単に装着することができるが、注射部位に注入補助具を装着した状態で押圧させると注入補助具が安定しない欠点があった。 However, since the above-mentioned injection assisting tool is attached to the tip of the syringe on the needle side, it can be easily attached by engaging a protrusion with the confirmation window for drug injection of the syringe body, but the injection assisting tool is attached to the injection site. There was a drawback that the injection assisting tool was not stable when pressed with the tool attached.

そのため、注射器に容易に装着できるとともに、注射部位に注入補助具を押圧させた状態でも安定することが可能な注入補助具が望まれている。 Therefore, there is a demand for an injection assisting tool that can be easily attached to a syringe and can be stabilized even when the injection assisting tool is pressed against the injection site.

本考案は、上記課題に鑑み、注射器の先端に装着する装着部と、前記装着部の下端からフランジ状に形成された押圧部と、が一体成形されたものであり、
前記装着部は、略筒状形状であり、注射器の先端を差し込む差込口と、注射針を通過させる開孔部と、前記開孔部の内周面に注射器のニードルカバーの周縁部を挟持する挟持部と、を有することを特徴とするものである。 In view of the above problems, the present invention is an integral molding of a mounting portion to be mounted on the tip of a syringe and a pressing portion formed in a flange shape from the lower end of the mounting portion.
The mounting portion has a substantially cylindrical shape, and holds an insertion port into which the tip of the syringe is inserted, an opening portion through which the injection needle is passed, and a peripheral portion of the needle cover of the syringe on the inner peripheral surface of the opening portion. It is characterized by having a holding portion and a holding portion.

また、上述した構成に加え、挟持部は、開孔部の内周面から中心軸方向に突出して形成された第１の突片と、前記第１の突片とは異なる高さの位置に突出して形成された第２の突片と、を有することが好ましい。 Further, in addition to the above-described configuration, the sandwiching portion is positioned at a position different from that of the first projecting piece formed by projecting from the inner peripheral surface of the opening portion in the central axis direction and the first projecting piece. It is preferable to have a second protruding piece formed.

また、上述した構成に加え、第１の突片は、底面側が押圧部の平坦面と同一平面上に位置するように開孔部の内周面の下端側に配設されることが好ましい。 Further, in addition to the above-described configuration, it is preferable that the first projecting piece is arranged on the lower end side of the inner peripheral surface of the opening portion so that the bottom surface side is located on the same plane as the flat surface of the pressing portion.

また、上述した構成に加え、第２の突片は、中心軸方向に突出して形成されるとともに、平面方向から見て、第１突片の間に位置するように配設されることが好ましい。 Further, in addition to the above-described configuration, it is preferable that the second projecting piece is formed so as to project in the central axis direction and is arranged so as to be located between the first projecting pieces when viewed from the plane direction. ..

上述した本考案によれば、注射器に容易に装着することができるとともに、注入器のニードルカバーの周縁部を挟持部で挟持することで、患者による自己注射を行う際に注射部位に対して注入補助具を押圧させても安定して接触させることができ、薬剤の注入を確実に行うことを補助することが可能である。 According to the present invention described above, the syringe can be easily attached to the syringe, and the peripheral portion of the needle cover of the injector is sandwiched between the holding portions to inject into the injection site when the patient performs self-injection. Even if the assisting tool is pressed, it can be stably contacted, and it is possible to assist the injection of the drug reliably.
