Accordingly, unlike a general one-time invasive scanning method, a resin needle is inserted into a blood vessel in a state in which a metal needle is advanced, a metal needle is taken out, and a flexible resin tube is connected to a ringer. That is, the metal needle is invaded in the blood vessel and then removed to guide the resin tube. As a result, only the flexible resin tube of the flexible material is inserted into the blood vessel to supply the ringer, thereby allowing the patient to be somewhat moved in the injected region.

Abstract

La présente invention porte sur un ensemble d'aiguilles apte à injecter un médicament liquide dans un vaisseau sanguin, par une aiguille externe, avec une seule injection, et en une seule fois sans avoir à remplacer l'aiguille interne introduite dans l'aiguille externe. L'aiguille externe est faite de matériaux souples comprenant un tube creux reliée à un récipient contenant le médicament. L'extrémité avant du tube insérée dans le vaisseau sanguin et le trou d'invasion sur le côté permet d'injecter le médicament. L'aiguille interne est inséré dans le trou d'invasion, guide l'extrémité avant du tube dans le vaisseau sanguin, puis est retirée.
