An insertion tool for inserting a catheter into a body of a patient is disclosed. The insertion tool unifies needle insertion, guidewire advancement, and catheter insertion in a single device. In one embodiment, the insertion tool comprises a housing in which at least a portion of the catheter is initially disposed, a hollow needle distally extending from the housing with at least a portion of the catheter pre-disposed over the needle, and a guidewire pre-disposed within the needle. A guidewire advancement assembly is also included for selectively advancing the guidewire distally past a distal end of the needle in preparation for distal advancement of the catheter. In one embodiment a catheter advancement assembly is also included for selectively advancing the catheter into the patient. Each advancement assembly can include a slide or other actuator that enables a user to selectively advance the desired component.

The present invention addresses the problem of simplifying the structure and reducing the number of parts by having wings also serve as a safety cover, and of eliminating the inconvenience of mutual interference between the wings and safety cover. The solution is a winged injection needle 1 comprising an injection needle main body 2, a base 3 that supports the base end of the injection needle main body 2 and wings 4 that protrude from the base 3 toward the left and right sides to function as handles, the wings 4 being constructed with plate members that are freely foldable through hinge sections 4a, 4b, 4c, so that in the folded state, they protrude from the base 3 toward the left and right sides to function as handles, while in the expanded state, they extend from the base 3 along the injection needle main body 2 toward the leading edge of the injection needle to function as a safety cover that covers the injection needle main body 2.

A needle-based medical device and method of manufacturing the same are disclosed. A needle device includes a hub having a longitudinal axis; a needle having a sharp distal tip; and a needle shield assembly associated with the needle and moveable from a non-shielding position to a shielding position. In the shielding position, the sharp distal tip is covered by at least part of the needle shield assembly. A latch is further provided for engaging with the hub when the needle shield assembly is in the non-shielding position; as well as a locking member operably connected to the needle shield assembly, and located at least partially within the hub when the needle shield assembly is in the non-shielding position. The latch and locking member lock the latch to the hub, such that when the needle shield assembly moves into the shielding position, the locking member moves generally proximally, unlocking the latch.

A needle shield (110) for an injection needle assembly (100) is provided. The needle shield (110) comprises a proximal base plate (111), said base plate (111) having an opening (113) for allowing a needle shaft (103) to run there through, and a distal cover plate (115), said cover plate (115) having an opening (116) for allowing the needle shaft (103) to run there through. A skin adhesive material is arranged on the distal side of the distal cover plate (115). An injection needle assembly (100) comprising such a needle shield is also provided.
