| 摘要 |
A method and apparatus for arterial and venous blood sampling is described. The apparatus includes efficient structure for purging the fluid line and a fluid sampling device chamber of residue heparinized IV solution to obtain a sufficiently undiluted blood sample without excessive blood waste and risk of entry of air, line contamination/nosocomial infection or misdiagnosis. The apparatus is also specially designed to protect the clinician from either self-contamination from patient fluids or accidental injury from needle puncture. |
