  • Patent number: 12042145
    Abstract: An insertion device includes an insertion component that inserts a medical device into body tissue of a user. The insertion device also includes an insertion component retractor, a cap, a guide sleeve having a ramp, an insertion sleeve and an elastic member. For inserting the medical device, the cap, the insertion component retractor and the insertion sleeve are movable relative to the guide sleeve from a distal position to a proximal position. The ramp twists the insertion component retractor relative to the guide sleeve and the insertion sleeve when the cap is moved from its distal position to its proximal position. The cap is movable from its proximal position to its distal position and the insertion component retractor is thereby moved from its proximal position to its distal position. An associated method of using the insertion device is also disclosed.

  • Patent number: 9302077
    Abstract: The present invention discloses a catheter instrument 1000 comprising a needle tip shielding device 100. The needle tip shielding device 100 is comprising a body with a rear side 106, a front side 107, an outer surface 108 connecting the rear side 106 and the front side 107, a hole 102 extending from the rear side 106 to the front side 107, a resilient arm 103 extending at an attachment point 105 from the front side 107 of the body, and a longitudinal arm 112. The resilient arm 103 has a resting state, from which it may be forced to yield free passage through the hole 102 in an axial direction of the body. The resilient arm 103 is adapted for protecting a needle tip 304 of a hollow needle 303 extending through the hole 102 in a direction from the rear side 106 to the front side 07, when the resilient arm 103 is in the resting state. The resilient arm 103 has one external point of contact, the point of contact being a contact with the hollow needle 303 when the hollow needle 303 is in a forward position.

  • Publication number: 20150141776
    Abstract: A subcutaneous access device has a skin attachment plate coated with an adhesive layer. The skin attachment plate is moveably linked by a retraction mechanism to a needle support with fixedly positioned needles. In the ready-to-use position the skin attachment plate is spaced away from the needle support and covers the fixedly positioned needles. Subcutaneous insertion of the needles is effected by attachment of the skin attachment plate with the adhesive layer to the skin and releasing the retraction mechanism, thus triggering the pulling of the attached skin with high velocity against the tip of the needles.
