Needle protector assembly

摘要

The invention relates to a needle protector assembly (10) comprising a needle defining an axial direction and a protective cover for the needle. The needle is attached to a needle hub which is provided with wings on opposite sides thereof and which can be moved relative to the protective cover between a distal position in which at least a tip of the needle protrudes from the protective cover, and a proximal position in which the needle is fully received in the protective cover. The protective cover comprises first (26) and second parts (28) which together form an elongate housing along which the needle hub can move between the distal and proximal positions, wherein the first and second parts define elongate slots on opposite sides of the housing through which the wings (16) protrude.

1. A needle protector assembly comprising a needle defining an axial direction and a protective cover for the needle,
wherein the needle is attached to a needle hub which is provided with wings on opposite sides thereof and which can be moved relative to the protective cover between a distal position in which at least a tip of the needle protrudes from the protective cover, and a proximal position in which the needle is fully received in the protective cover, wherein the protective cover comprises first and second parts which together form an elongate housing along which the needle hub can move between the distal and proximal positions, wherein the first and second parts define elongate slots on opposite sides of the housing through which the wings protrude, and wherein the first and second parts are connected to one another by a film hinge in the region of a first axial end of the housing and by a latching mechanism in the region of a second axial end of the housing; wherein a locking mechanism is provided which is adapted to secure the needle hub in the proximal position, wherein the locking mechanism comprises a pair of first and second locking means engaging with each other when the needle hub is in the proximal position, wherein the first locking means is provided on the needle hub and the second locking means is provided on the protective cover, and wherein the first locking means is formed such that a radial dimension of the first locking means is reduceable against a restoring force; wherein the first locking means has a ramp-like shape with the radial dimension increasing towards the tip of the needle; wherein the second locking means comprises an opening in the protective cover which is adapted to receive the first locking means when the needle hub is in the proximal position.
