ABSTRACT:
A syringe device for obtaining an arterial blood sample is provided. The syringe device includes a syringe barrel, a plunger assembly having a sealing plug and a filter member. The syringe device preferably includes a carrying device including an anticoagulant and a carrying device body. The carrying device body is made of a hard, non-porous material. The filter member permits the passage of air while preventing the passage of blood. The filter member has a periphery that is in contact with the inner wall of the syringe barrel so that the air does not pass along the inner wall past the filter member. Preferably, the filter member is detached from the sealing plug. During operation, a blood sample from a patient is received in a blood receiving area defined in the syringe barrel, while displaced air passes through the filter member and is substantially contained between the filter member and the sealing plug.
