摘要:
A passive latch ring safety shield for use with medical injection devices is disclosed. The safety shield includes an inner sheath defining a channel which is dimensioned to receive an injection device and an outer sheath defining a channel which is dimensioned to slidably receive the inner sheath. A biasing member is provided between the inner and outer sheaths to urge the outer sheath in relation to the inner sheath from a retracted position to an advanced position. A resilient latch ring is supported on the safety shield in a position to prevent movement of the outer sheath in relation to the inner sheath from a retracted to and advanced position. The latch ring is deformable in response to actuation of the injection device to disengage the outer sheath from the inner sheath and allow the biasing member to move the outer sheath from the retracted position to the advanced position in relation to the inner sheath.
