具有注射及抽血功能的安全器械 Safe injection equipment and blood function

技术领城 Technical collar city

本发明属于将介质输入及抽出体内器械部件,特别是一种具有注射及抽血功能的安全器械. The present invention is in the extraction medium and the input device body member, particularly to a safety device having a function of injection and blood.

背景技术 Background technique

一般静脉注射时,主要系借由如困1所示的静脉注射器1作为输入药剂或抽血的器具。 When a general intravenous injection, mainly by means such as intravenous syringe trapped appliance 1 shown in the blood as an input or an agent.

静脉注射器l包括中空状针座ll、中空的针体12、中空的衔接件13及与衔接件13固接且为中空可挠弯的导管14. L intravenous syringe comprises a hollow hub ll, 12, 13, and a hollow adapter engagement member and the hollow needle 13 and is fixed to a hollow flexible conduit 14 bends.

针座11以一端111与针体12固接及与衔接件13套固,使针体12由导骨14穿出。 11 to the needle hub 111 and needle 12 fixed to one end of the adapter and the bushing securing member 13, the needle 12 piercing the bone 14 by the guide. 借此,医护人员以针体12穿刺入动物体的血管内,就可藉以导引导管14进入血管,且能在针体12抽出后,将导管14留置于血管内,凭借导管14可挠弯的特性,避免动物体有不舒适的感觉。 Thus, the health care workers to the blood vessel into the animal body within the needle bodies 12, 14 can thereby guiding catheter into the blood vessel, and can be withdrawn after the needle body 12, the catheter 14 is placed inside a blood vessel, a catheter with a flexible bend 14 features animals have to avoid discomfort.

此时,衔接件13可供点滴的输送管或填装有药剂的针筒连接,进行静脉注射;或以空的针筒进行抽血的动作. At this time, the engagement member 13 for the delivery tube or drip syringe filled with drug connection, intravenously; or empty syringe for blood operation.

惟,上述静脉注射器1虽然可作为输入药剂或抽血的器具,但在实际使用时,仍存有以下缺失而亟待解决: However, although the above-described intravenous syringe 1 can be used as an input appliance blood or an agent, but in actual use, there is still to be solved the following deletions:

1、医护人员抽出针体12后,通常必须立即进行抽血或输入药剂的动作, 因此,医护人员为了方便,常常会先将针体12连同针座11先摆置在施行注刮操作的作业范围内或操作盘内,或插置在作业范围内可固定针体12的物件上-如病床床沿,以避免针体12不慎伤及操作者或病人,待静脉注射或抽血作业完成后,再分别收集、处理'因此,针体12无法避免有棵露在外的情形,所以,只要稍有不慎,就会有刺伤医护人员的情形,造成伤痛甚或感染爱滋病、 II型肝炎、HI型肝炎……等致命传染疾病的危险。 1, after 12 out staff, must generally be blood or needle immediately medicament input operation, therefore, the medical staff for convenience, often along with the first needle 12 injection purposes job scraping operation hub body 11 to the arrangements and or the range of the operation panel, or the needle insertion may be fixed object 12 in the operating range on - the bed, such as bed, the needle body 12 to avoid inadvertent injury to the user or patient, to be injected intravenously or blood job is complete , and then were collected, processed 'Therefore, the needle 12 can not avoid trees exposed outside the case, so long as the slightest mistake, there will be situations stabbed medical staff, resulting in pain and even AIDS infection, hepatitis type II, HI ...... dangerous hepatitis and other deadly infectious diseases. 虽然,诸如美国专利第5989220、 6287278、 6117108号案,公开了可借由针座内的弹簧,将针体回拉在针座内,免除医护人员日常使用静脉注射器的伤害及恐惧。 Although US Patent No. 5,989,220, 6,287,278, No. 6,117,108, such as text, discloses a spring by means of the hub of the needle to pull back on the hub, eliminating the fear of injury and the medical staff daily use of intravenous syringes. 但管径极小且通常为塑胶射出成型制品的针座要另外安装金属制的弹簧及其他配合的组件,不但会增加组装上的困扰,且会增加材料、制造、检测成本,增加产品的不良率, 更会因为繁瑣的组装程序,使组件被污染的机会大幅提升。 However, a very small diameter and typically injection molding of plastic articles for a needle hub and spring to install other components of the metal complex, problems will not only increase the assembly, and increases the material, manufacturing, testing cost, increase product poor rate, but because of the cumbersome procedures of the assembly, the assembly is the chance of contamination increased dramatically.

2、 如图2所示,当针体12导引导管14进入血管后,虽然可借由透孔121, 使血液外渗至导管14与针体12的间隙,达到现血的功能,以示知医护人员已将针体12及导管14正确穿置在血管内,但是,在针体12周壁122上设置透孔121的技术手段,容易使尖细的针体12弯折;再者,如操作时,针体12与导管14整段隐没在皮下组织或血管内时,就会失去现血的功能,且由于针体12相当尖细,并与导管14贴合。 2, shown in Figure 2, when the catheter introducer needle 12 into the vessel 14, although the through hole 121 by means of the extravasation of blood into the gap of the catheter body 12 and the needle 14, the blood reaches the current function to show has been known to medical needle 12 and catheter 14 within the blood vessel penetration and correct, however, the technical means provided in the through hole 121 of the peripheral wall 12 of the needle body 122, easily bent tapered needle body 12; Furthermore, as when operating, the needle 12 and the catheter in the subcutaneous tissue or hidden the whole vessel 14, now will lose the function of blood, the needle body 12 and due to relatively tapered, with the conduit 14 and bonded. 当病人血压不足以使血液由透孔121渗出时, 就无法正确显示使用的状态。 When the patient's blood pressure is not sufficient to oozing from the through hole 121, the display state can not be used properly.

3、 另外,当针体12由导管14内抽出而导管14留置在血管内后,医护人员必须一手按压及固定衔接件13与导管14。 3. Further, when the indwelling catheter 14 in the blood vessel by the inner needle 12 is drawn out of the catheter 14, the medical staff must hand the pressing member and the fixing adapter 13 and the conduit 14. 因此,只能以另一手进行固接衔接件13与点滴或针筒的动作,从而存在操作不顺畅的缺失,尤其是以针筒采集血液做为检体时,更凸显出单手操作的不便。 Thus, only the operation of the syringe 13 and the intravenous or engagement member is fixedly connected to the other hand, so that there is a deletion operation is not smooth, particularly when a syringe is collected as a specimen of blood, but also highlights the inconvenience of the one-hand operation . 且衔接件13与针筒及点滴管线替换衔接时,容易因操作不慎导致衔接点的污染,从而造成血液遭感染的情形。 And the engaging member 13:00 Cohesion and replace syringes and drip line, easily lead to contamination due to careless handling point of convergence, resulting in the case of blood was infected. 再者,针筒取得血液后,必须再将血液转移入集血管内保存送检,使静脉注射及血液采集的过程相当繁复,且潜伏易受污染的危机。 Moreover, the syringes to obtain blood, the blood must then be transferred into submission intravascular save set, and the intravenous blood collection process is complex and susceptible to contamination and potential crisis.
