摘要：
A filtered needle for use in administering a liquid payload, including a needle and connector portion and a filtering needle cap. The filtering needle cap including a distal open end in fluid communication via an internal channel with a proximal open end of the filtering needle cap. The filtering needle cap proximal end sized to receive the distal end of the hub within the proximal end of the filtering needle cap to reversibly engage the hub when needle distal end is inserted into the internal channel. The filtering needle cap including a filter element and a seal to seal around an outside diameter of the hollow needle so that liquid payload is drawn into the lumen in the hollow needle as liquid payload is filtered and drawn into the fluid fitting. The filtering needle cap is designed to limit a dead volume of liquid payload drawn into the filtering needle cap but not entering into the distal end of the hollow needle.
