    • An apparatus (100) for collecting blood samples comprises a sleeve (1) having a substantially cylindrical body (10), hollow on the inside, defining an inner chamber (11) open at the front and rear, a needle assembly (5) comprising a needle-carrier (50) which carries at its opposite ends a first external needle (51) designed to be inserted into the patient's vein and a second internal needle (52) designed to engage in a vacutainer-type test tube, and a safety device (7) having a substantially cylindrical hollow body (70) defining an inner chamber (71) able to receive the vacutainer-type test tube. The safety device is able to support the needle assembly (5) so that the internal needle (52) is disposed axially inside the chamber (71) of the safety device and the safety device (7) is mounted movably inside the chamber (11) of the sleeve (1) to pass from a working position in which the external needle (51) protrudes axially outward from the sleeve (1) to a safe position in which the external needle (51) is protected inside the chamber (11) of the sleeve (1) and the internal needle (52) is protected inside the chamber (71) of the safety device (7).
    • 用于收集血液样本的装置(100)包括具有基本上圆柱形本体(10)的套筒(1),其在内部具有中空,限定在前部和后部开口的内部腔室(11),针组件(5)包括 针托架(50),其相对端承载设计成插入患者静脉的第一外针(51)和设计成接合在真空管型试管中的第二内针(52),以及安全 装置(7)具有基本上圆柱形的中空本体(70),其限定能够接收该真空管式试管的内室(71)。 安全装置能够支撑针组件(5),使得内针(52)轴向地布置在安全装置的腔室(71)内部,并且安全装置(7)可移动地安装在腔室(11)内, 所述套筒(1)从所述外针(51)从所述套筒(1)的轴向向外突出的工作位置通过到所述外部针(51)在所述腔室(11)内被保护的安全位置 套筒(1)和内针(52)被保护在安全装置(7)的腔室(71)内。
