Title:
抗凝固剤で内側を被覆した針
Document Type and Number:
Japanese Patent JP4439114
Kind Code:
B2
Abstract:
To prevent blood from clotting or being diluted (which causes inaccuracy in the measurement of the characteristics of blood drawn from a patient), a needle assembly has the interior portion of its cannula and at least one portion of its hub covered by a dry coat of anticoagulant. To provide the dry coat of anticoagulant onto the interior surfaces of the cannula and the hub, a liquid anticoagulant is atomized thereto so that an even coat of the anticoagulant is provided to the interior surfaces of the cannula and hub. The volume and concentration of the anticoagulant atomized to the inside of the needle assembly are controlled as the liquid anticoagulant is ultra-sonically atomized to the interior portion of the needle assembly.
