摘要：
A shielded indwelling needle, particularly a shielded indwelling needle with external application wings (5). The shielded indwelling needle comprises a puncture component (1), an indwelling cannula component (2) comprising a cannula holder (2.1), a shield (3), and the application wings (5), and is characterized by the application wings (5) being a separate structure relative to the indwelling cannula component (2) or being movably connected to the cannula holder (2.1) as movable application wings. When preparing for puncture, a front section of the cannula holder (2.1) exposed from the shield (3) is pushed forward to enter an application wings sleeve cavity (5.3) to achieve engagement of the cannula holder (2.1), or the application wings are connected to an attachment component exposed from the shield (3) to form attached application wings, the bottom of the attachment component passing through a slot (3.1) of the shield (3) to connect to the cannula holder (2.1). Compared to the prior art, the application wings (5) are provided outside the shield (3) and do not occupy an inner cavity of the shield (3), allowing a thinner main body of the shield (3), resulting in ease of use. Wings (5.2) can also be turned and folded, allowing the entire indwelling needle to occupy less space, achieving convenient storage.L'invention concerne une aiguille à demeure blindée, en particulier une aiguille à demeure blindée à ailes d'application externes (5).
