The present application discloses a needle tip shielding device for protection of a needle tip of a needle. The needle tip shielding device comprises a fixing arrangement having a proximal side and a distal side, which fixing arrangement is comprising at least one engaging element, which engaging element is resilient and resiliently striving from a compressed state towards an expanded state, in which expanded state the shortest distance between a point of said engaging element and the central axis of said needle tip shielding device is longer than the shortest distance between said central axis and any other point of said needle tip shielding device. A catheter instrument comprising the needle tip shielding device and a method for manufacturing is also disclosed.

Needle tip shielding device and fixing arrangement

The present invention discloses a catheter instrumentcomprising a needle tip shielding device, a catheter huband a needle unit, wherein the needle unitis provided with connecting meansfor connection to the catheter hub, and with connecting meansfor connection to an external device. The needle tip shielding deviceis comprising a body with a rear side, a front side, an outer surfaceconnecting the rear sideand the front side, a holeextending from the rear sideto the front side, and a resilient armextending at an attachment pointfrom the front sideof the body; wherein the resilient armhas a resting stale from which it may be forced to yield free passage through the holein an axial direction of the body, the resilient armbeing adapted for clamping a needle tipof a hollow needleextending through the holein a direction from the rear sideto the front side, when being in the resting state.

Catheter needle tip shielding device

The present invention discloses a catheter instrumentcomprising a needle tip shielding device. The needle tip shielding deviceis comprising a body with a rear side, a front side, an outer surfaceconnecting the rear sideand the front side, a holeextending from the rear sideto the front side, a resilient armextending at an attachment pointfrom the front sideof the body, and a longitudinal arm. The resilient armhas a resting state, from which it may be forced to yield free passage through the holein an axial direction of the body. The resilient armis adapted for protecting a needle tipof a hollow needleextending through the holein a direction from the rear sideto the front side, when the resilient armis in the resting state. The resilient armhas one external point of contact, the point of contact being a contact with the hollow needlewhen the hollow needleis in a forward position. The longitudinal armhas one external contact point, the contact point being a contact with the hollow needlewhen the hollow needleis in a forward position. Any straight imaginary line extending longitudinally through the holein the axial direction of the body coincides with the resilient arm, when the resilient armis in the resting state.
