Embodiment
[0018] The mechanized needle loading technology for infusion needles described in this embodiment is to set up and control the orientation of the beveled surface of the needle head during the flow of the needle tube, so as to complete the oriented slope in which the beveled surface of the needle tip of the infusion needle is basically parallel to the wing surface of the needle seat. flat. The directional inclined plane contains continuous transitional inclined planes in the stepped parallel grooves, and the transitional inclined planes are made of materials containing metal or non-metal or a combination of metal and non-metal. After the needle tube slides down the groove, it rotates around its own axis due to vibration. When the inclined surface of the needle point and the oriented inclined plane meet, the needle tube no longer rotates, ensuring the orientation of the needle tube. The infusion needle is shown in Figure 1 and Figure 2.
