そして、注射部位に対して注入補助具１の押圧部１３を押し当てるとともに、手の平側で注射部位の周辺を安定して押圧することで、注射部位及びその周辺の皮膚を撓ませることなく固く張らせる。 Then, by pressing the pressing portion 13 of the injection assisting tool 1 against the injection site and stably pressing the periphery of the injection site with the palm side, the injection site and the skin around the injection site are firmly stretched without bending. Let me.

次に、注射器２の先端を案内部１０の差込口１２ａから開孔部１１ａまで案内させ、開孔部１１ａの周囲の当接部１１ｂに注射器２のニードルカバー２０を当接させた後、さらに注射器２を押し込むことで注射針２１を確実に突出させるとともに、注射部位に対して垂直方向から穿刺させ、薬剤を注入する。その後、薬剤を注入したことを切欠部１２ｃに位置する確認窓２２で確認する。 Next, the tip of the syringe 2 is guided from the insertion port 12a of the guide portion 10 to the opening portion 11a, and the needle cover 20 of the syringe 2 is brought into contact with the abutting portion 11b around the opening portion 11a. Further, by pushing the syringe 2, the injection needle 21 is surely projected, and the injection needle 21 is punctured from the direction perpendicular to the injection site to inject the drug. After that, it is confirmed by the confirmation window 22 located in the notch 12c that the drug has been injected.

したがって、上述した注入補助具１は、患者による自己注射を行う際に、注射器２に装着せずに、注射部位に対して垂直方向から注射器２を案内することができ、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。 Therefore, the above-mentioned injection assisting tool 1 can guide the syringe 2 from the direction perpendicular to the injection site without being attached to the syringe 2 when the patient performs self-injection, and the injection of the drug is surely performed. It is possible to assist in doing.

また、人差し指及び中指で案内部１０の外側面を挟み込んで保持した状態で注射部位を押圧するとともに、注射部位の周囲を手の平側でも押圧することで、注射部位の皮膚を撓ませることなく固く張るようにすることで、注射針２１の穿刺による痛みを軽減することが可能である。 In addition, the injection site is pressed while the outer surface of the guide portion 10 is sandwiched and held by the index finger and the middle finger, and the circumference of the injection site is also pressed on the palm side to firmly stretch the skin of the injection site without bending. By doing so, it is possible to reduce the pain caused by the puncture of the injection needle 21.

上記の実施形態では本考案の好ましい実施形態を例示したが、本考案は上記の実施形態に限定されるものではなく、実用新案登録請求の範囲に記載した範囲内で改善や変更が可能である。例えば、押圧部１３は、脚部や腕部などの注射部位に対して適するように形状を変更してもよく、例えば、円板形状を多角形状にしてもよい。 Although the above-described embodiment exemplifies the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment and can be improved or changed within the scope of the utility model registration claims. .. For example, the pressing portion 13 may be changed in shape so as to be suitable for an injection site such as a leg or an arm, and for example, the disk shape may be a polygonal shape.
