Device permitting arterial or venous blood sampling by vacutainer system into a syringe
Abstract
Abstract The invention relates to a device permitting the transfer of arterial or venous blood into a syringe without any risk of contamination by the blood or by prick injuries. This device consists of a cylindrical body 1 recessed in its centre on each side 2 and made of plastic or rubber material, serving as a piston for the vacutainer. One of the ends will be of the Luer-Lok cone type 3 having a female part 4 fitting perfectly on a syringe 9 with a male Luer-Lok end piece 11. The other end consists in the central part of a latex membrane 5 which must be centred relative to the Luer-Lok cone 11 of the body of the syringe. When the user drives the piston 1 towards the means protecting the needle 2 of the vacutainer 10 under pressure, the means protecting the needle 2 will be broken, thereby freeing the bevel of the needle 2, which will then be able to pass through the membrane 5 of the device and release the blood into the boy of the syringe 9 provided for this purpose. Once the syringe is filled, the user disconnects the syringe/device assembly 1, 2, 3, 4, 5, 6, 7 in a firm movement, ensuring the integrity and the leakproofness of the blood sample destined for the laboratory. <IMAGE>
