Vorrichtung zum einmaligen Gebrauch zur Entnahme und Aufbewahrung von Blutproben.

摘要

In a single-use device for collecting and holding blood samples, provision is made for an evacuated tube (10) with a closure (stopper) (11) that can be pierced by the tip of a needle (13), the other tip (14) of which is intended to be inserted into a vein of a patient. Disposed below the said pierceable stopper (11), and in the tube (10), is a diaphragm (16) intended to be passed through by the needle-tip (13) that pierces the stopper (11), so as to form a supplementar barrier between the interior of the tube (10) and the environment when the pierceable stopper (11) is removed.
