Anti-needlestick device

Abstract

A needlestick prevention device (100) for an injection needle carried by a needle support member (101) of a syringe (102), said device being formed as a one-piece moulding, and comprising a first part ( 103) and a second part (104), the first part (103) is adapted to be attached to the needle support member (101), the second part (104) provides a shield for the needle and can be Pivotally moved to expose the needle for use. The device is adapted to adopt a first position, in the first position, the needle is protected for transporting the device before use, a second position, a third position, and a fourth position, in the second position, the needle Exposed for filling the syringe and making an injection, in a third position the needle is protected after filling of the syringe but before injection, in a fourth position the needle is locked in the device after injection. In one embodiment, said shield (104) has a transport recess (124) connected by a door arrangement (126) and a locking recess (125) arranged such that in the third position the needle (130) is in In said transport groove (124) and movable to a second position, and in a fourth position, the needle moves through a gate (126) into a locking groove (125), wherein the gate (126) prevents leaving the first Four position movement. The device also includes an energy dissipating tab (155) that acts to reduce the energy of the shroud (104) when the shroud (104) returns to the third position and before the gate device contacts the needle (130), so that Any liquid on the needle (130) is prevented from splashing out of the device.

Description

technical field [0001] The present invention relates to a needlestick prevention device for use with an injection device such as a syringe. Background technique [0002] In medical settings, particularly during use of a syringe or other injection device, needlestick injuries commonly occur when a user accidentally sticks the needle into himself or herself or into another person. Such needlestick injuries are a major cause of spreading infection and disease, and are painful and can lead to loss of mobility, so it is important to prevent them. [0003] There are various known methods of attempting to prevent needlestick injuries. Injection needles are typically provided with protective caps that are removed for use and then discarded since repositioning the protective cap on the needle is not recommended. In fact, resetting the protective cap is believed to be responsible for a large number of needlestick injuries. [0004] The needle itself may be mounted on a cylindrical ...

Problems solved by technology

If there is any blood on the tip of the needle, the vibration can dislodge the blood causing the blood to splatter and possibly be ejected from the device, creating a hazard for the user
