Injection needle head for insulin injection pen, needle head picking device and needle head set

Abstract

The invention provides an injection needle head for an insulin injection pen, a needle head picking device and a needle head set. The injection needle head comprises a connecting base and a puncture needle fixed to the connecting base, and a limiting ring and a limiting head are arranged on the outer circumference of the base. The needle head picking device is used in cooperation with injection needle heads and comprises a fixed shell, a movable shell and a reset spring. The injection needle head set comprises a plurality of injection needle heads and one needle head picking device. The injection needle head for the insulin injection pen is matched with the picking device for use, so that on the one hand, the needle head and the injection pen can be assembled and disassembled under the condition that the needle head is not exposed; and on the other hand, after injection is finished, under the condition that the needle head is not in contact, separation between the needle head and the head can be achieved, and the used needle head is placed in a corresponding collecting box. In the whole injection process, the hand of a medical worker does not make contact with the needle head, and the situation that the medical worker is accidentally injured by the needle head is reduced to the maximum extent.
