Device for taking blood from a patient and for transferring it to a test tube under vacuum. |
摘要 |
The hollow tubular device 1 has one extremity 2 open and communicating with the outside and one closed by a flat end wall 3 which is substantially perpendicular to the longitudinal axis of the device 1 and is traversed by a hole 4; from the external surface of said end wall 3 there extends, towards the outside and all round said hole 4, a conical coupling 5 for an injection needle of a standard type and, in the proximity of said end wall 3, the internal tubular wall of said device 1 has a circumferential relief 6 which defines a seat suitable for sealingly receiving the base 7 of a hollow needle 8, said base 7 having a surface substantially equal to that of said end wall 3 against which it goes to coincide. <IMAGE> |
