Description
技术领域Technical Field
本实用新型涉及留置针装置领域，特别是涉及一种密闭式防针刺伤型静脉留置针的采血装置。The utility model relates to the field of indwelling needle devices, in particular to a closed needle-puncture-proof venous indwelling needle blood sampling device.
背景技术Background Art
使用静脉留置针是一项新的护理操作技术，它已逐步取代了传统的头皮钢针。较传统的头皮钢针其输液优点是：留置的套管在静脉内可留置时间长，且不易刺破血管壁。静脉留置针的套管是有穿刺针引导进入人体静脉血管的，因此在套管穿刺到位后，引导用的穿刺针需退出并丢弃，在这个过程中，护士操作一不小心就极易被退出的穿刺者刺伤，或因害怕刺伤而影响到对留置针的操作。目前，我国许多医院都将静脉留置针作为临床护理和治疗的主要工具，但基本上都是非防针刺伤型的留置针，每年国家需从国外进口大量的防针刺伤型留置针，主流的防针刺伤型静脉留置针在穿刺成功退针后，针尖会回收在保护装置中，避免了护士在操作过程中被刚丢弃的穿刺针刺伤造成血液感染。The use of intravenous indwelling needles is a new nursing operation technology, which has gradually replaced the traditional scalp steel needles. Compared with the traditional scalp steel needles, the advantages of infusion are: the indwelling cannula can be indwelled in the vein for a long time and it is not easy to puncture the blood vessel wall. The cannula of the intravenous indwelling needle is guided into the human vein by the puncture needle. Therefore, after the cannula is punctured in place, the guiding puncture needle needs to be withdrawn and discarded. In this process, the nurse is very likely to be stabbed by the withdrawn puncturer if he is not careful, or the operation of the indwelling needle is affected by the fear of puncture. At present, many hospitals in my country use intravenous indwelling needles as the main tool for clinical nursing and treatment, but they are basically non-anti-needlestick indwelling needles. Every year, the country needs to import a large number of anti-needlestick indwelling needles from abroad. After the mainstream anti-needlestick intravenous indwelling needle is successfully withdrawn, the needle tip will be recovered in the protective device, which avoids the nurse from being stabbed by the just-discarded puncture needle during the operation and causing blood infection.
在现有技术中，常用到的留置针结构，分为包含肝素帽、钢针的类型和不包含二者结构的，然而，带有肝素帽和钢针的留置针在生产和采购上成本均较高，影响大规模使用，而不带有二者结构的，容易从密封处脱落，进而血液会污染到手，增加直接暴露的机会。In the prior art, commonly used indwelling needle structures are divided into types including a heparin cap and a steel needle and a structure that does not include both. However, the indwelling needle with a heparin cap and a steel needle has high production and procurement costs, which affects large-scale use. The indwelling needle without the two structures is easy to fall off from the seal, and then blood will contaminate the hands, increasing the chance of direct exposure.

作为本实用新型的一种优选技术方案，所述软管为透明PVC软胶管结构。As a preferred technical solution of the utility model, the hose is a transparent PVC soft rubber hose structure.
作为本实用新型的一种优选技术方案，所述鲁尔接头、保护套和钢针均为空心结构。As a preferred technical solution of the utility model, the Luer connector, the protective sleeve and the steel needle are all hollow structures.
