技术领域technical field
本发明属于医疗器械技术领域，涉及一种静脉穿刺采血装置。The invention belongs to the technical field of medical devices, and relates to a venipuncture blood collection device.
背景技术Background technique
医院进行静脉采血时，需要护士消毒处理患者皮肤后进行静脉穿刺。护士手动使用静脉穿刺针和真空采血管采血时，要注意力高度集中，劳动强度比较大。由于护士静脉穿刺水平的不同，存在一定的失误率，容易造成病人的二次疼痛等。此外，穿刺针较为锋利，护士误操作会扎伤自己，有感染传染性疾病的风险。When venous blood collection is performed in the hospital, nurses are required to disinfect the patient's skin and perform venipuncture.
