Abstract
Stabbing accidents are prone to occur to people handling needles, for example when recapping a needle or when trying to remove a needle from a syringe. A device is provided for safe and automatic removal of a needle from a syringe aimed to prevent stabbing accidents. The device is arranged to grab hold of and rotate the needle of a syringe. The needle, after being rotate off the syringe is discarded into the device by releasing the grip on the needle. The device rotates two rotating gears relative to each other to move grippers towards the needle, and rotates the two gears together to rotate the needle relative to the syringe which may be held by the user.
Claims12
A device for rotating a needle off of a syringe, the device comprising a rotation mechanism comprising:
- a first rotatable gripper hub arranged to be driven by a first driving unit comprised by the device, the first gripper hub having a first central opening and the first gripper hub being arranged to be rotated around an axis of rotation;
- a second rotatable gripper hub arranged to be driven by a second driving unit comprised by the device, the second gripper hub having a second central opening aligned with the first central opening and the second gripper hub being arranged to be rotated around the axis of rotation;
- a first gripper unit having a first gripping section for engaging with the needle and a second gripper unit having a second gripping section for engaging with the needle,
- wherein the first gripper unit and the second gripper unit are mounted to the first gripper hub and the second gripper hub such that if the first gripper hub is rotated relative to the second gripper hub, the first and second gripping sections move towards the axis of rotation, and
- wherein the first gripper unit and the second gripper unit are rotatably connected to a first of the first gripper hub and the second gripper hub and slidably connected to a second of the first gripper hub and the second gripper hub;
- and
- a controller arranged to:
- operate one of the first driving unit and the second driving unit such that the first gripper hub is rotated relative to the second gripper hub in a first direction for moving the first gripping section and the second gripping section towards the axis of rotation;
- and
- operate the first driving unit and the second driving unit such that the first gripper hub and the second gripper hub rotate at substantially the same annular speed around the axis of rotation.
