BLOOD EXTRACTION DEVICE HAVING A HOLDER AND A SHARPENED-END CANNULA |
摘要 |
A blood extraction device has a holder with a hollow needle cannula anchored therein. A rear end portion of this cannula is surrounded by a closed-end elastic hose like valve rubber tube with an air gap between the tube and the cannula. With a minimum of effort and cost a reliable anchorage of the valve rubber tube in the holder is obtained by pressing a clamping member within the holder against the exterior of the valve rubber tube and thereby plastically deforming this clamping member. |
