ABSTRACT:
An arterial blood gas syringe is disclosed for obtaining an arterial blood sample. The syringe is characterized by a sealing plug having channels formed in an upper surface thereof for use in removing air as arterial blood is received into the syringe. Each of the channels extends in a generally radial direction and the channels converge near the center of the sealing plug. A filter element is contained in the center of the sealing plug for permitting the passage of air directed thereto using the channels. The filter element permits the passage of the air but prevents passage of the blood.
