Abstract
A method of collecting a blood sample, such as from an artery, in a flexible tube collector while forcing at least a portion of the air in the collector through a 'nonwet' filter by means of blood pressure. This nonwet filter prevents escape of blood from the collector. The blood containing blood sampler can then be chilled in an ice bath if a test is not run immediately, and then the test sample dispensed to a machine for testing the partial pressure oxygen and carbon dioxide in the blood. If the machine does not have a vacuum extractor, blood can be stripped from the tube by a movable clamp structure.
