摘要：
Disclosed is a safety needle assembly comprising a needle head (10) which comprises a needle seat (12) and a needle (11) installed on the needle seat (12), and a needle head protective device (1) comprising a protection arm (6) and an installation part (2) on one side of the protection arm (6) there is an opening (60) integrally connected with the installation part (2) in a rotatable manner through a hinge member (4) the protection arm (6), relative to the installation part (2), is centred on the hinge member (4) and rotates to the protective position in which the needle (11) enters the interior of the protective arm (6) through the opening (60). When the protection arm (6), relative to the installation part (2), is rotated to the protective position, a pair of first engagement members (7) located on both sides of the installation part (2) are engaged with a pair of second engagement members (8) located on both sides of the protection arm (6) respectively. Between the needle seat (12) and the needle seat hole (21) of the installation part (2) is formed a convex-concave structure capable of preventing the needle seat (12) and the needle seat hole (21) from axial and circumferential relative movement. The safety needle assembly can not only prevent accidental punctures after using medical instruments such as an injection syringe with a needle head and hemostix etc., but also has a simple structure and low cost.La présente invention concerne un dispositif daiguille de sécurité comprenant une tête daiguille (10) qui comprend un siège daiguille (12) et une aiguille (11) installée sur le siège daiguille (12), et un dispositif protecteur de la tête daiguille (1) comprenant un bras de protection (6) et une partie dinstallation (2) de lautre côté du bras de protection (6) se trouve une ouverture (60) solidairement connectée à la partie dinstallation (2) de façon rotative par lintermédiaire dun élément charnière (4) le bras de protection (6), par rapport à la partie dinstal
