Embodiment Construction

[0062] In this application, the distal end of a component or device is to be understood as the end furthest from the user's hand, and the proximal end must be understood as the end closest to the user's hand. Thus, the distal direction should be understood as the direction further away from the user's hand, while the proximal direction is the opposite direction, ie towards the user's hand. The proximal direction and the distal direction are parallel to the direction in which the needles of the medical container are to extend. A radial direction should be understood as a direction perpendicular to the proximal and distal directions.

[0063] figure 1 An exploded perspective view of a medical device 1 according to an example is shown. The medical device 1 generally has an elongated shape extending along an axis A, which may also be referred to as a "central axis" in this application.

[0064] The medical device 1 includes a medical container 100 and a needle 102 attached to a...

Abstract

The invention relates to a safety assembly for preventing needle stick injury for preventing needle stick injury with a needle (102), the needle having a proximal end (120) fixed to a tip (106) of a medical container(100)and a pointed distal end (118),the safety assembly comprising: - an attachment ring (20) configured to be attached to the tip (106) of the container (100); - a safety device (60,70) configured to cover at least the distal end (118) of the needle, the safety device being attached to the attachment ring (20). Said attachment ring (20) comprises: an inner ring (21) having an inner face provided with a snap feature, the snap feature being configured to engage a complementary snap feature on the tip of the container in order to prevent axial movement of the inner ring with respect to the container, the snap feature being configured to move radially to engage the complementary snap feature on the tip of the container; an outer ring (22) fixed on the inner ring (21), the outer ring (22) comprising a sleeve portion (24) configured to surround at least a portion of the inner ring in order to prevent radial movement of the snap feature (25a) once the snap feature has engaged the complementary snap feature on the tip of the container.

Description

technical field [0001] The present invention relates to a safety assembly for preventing needlestick injuries by needles of a medical device, and also to a medical device provided with such a safety assembly. Background technique [0002] Medical devices provided with sharp needles are a daily practice in medical institutions in order to inject or sample a patient's tissue, vein or artery. Medical devices having needles may include, but are not limited to, injection devices such as syringes, pen injection devices, catheters, or blood collection devices. The sharp points of these medical devices present an inherent risk of needlestick injury to medical personnel and / or patients and are therefore usually covered by protective caps prior to use. Such a cap not only protects the needle from contamination, but also avoids unwanted contact or puncture that may occur during transportation and delivery of the medical device. Clearly, such caps need to be removed immediately before...
