Description

一种中心静脉穿刺针 One kind of central venous puncture needle

技术领域 FIELD

[0001] 本发明涉及一种中心静脉穿刺针,特别是一种只需穿刺一次成功后就能顺利置入中心静脉导管、穿刺并发症少成功率高的改进的中心静脉穿刺针,属于医用器械技术领域。 [0001] The present invention relates to a central venous catheter, in particular, the latter can only successful puncture smoothly inserted central catheters, puncture fewer complications success rate improved central venous catheter, a medical device belonging to technology.

背景技术 Background technique

[0002]目前临床上,常用的中心静脉穿刺器械行中心静脉穿刺的方法(以后路右侧颈内静脉穿刺为例):1)患者仰卧位,头偏向左侧,穿刺部位常规消毒,铺洞巾;2)选择胸锁乳突肌锁骨头后缘与锁骨上两横指处为穿刺点,局部麻醉;3)用5ml注射器接7号针向胸锁关节方向穿刺,针体保持水平位,注射器保持负压;4)注射器回抽到暗红色血液并通畅,确定穿刺针在颈内静脉,退出7号针或固定7号针同时卸下注射器,另用5ml蓝针管注射器接18G钢针沿着7号针的方向穿刺,回抽到暗红色血液并通畅,确定穿刺针在颈内静脉,经蓝色注射器尾部置入导丝250mm ;5)固定导丝,退出18G钢针,通过导丝置入扩张管扩张穿刺点皮肤至血管——穿刺径路;6)固定导丝,退出扩张管,通过导丝置入中心静脉导管120mm ;7)固定导管,医用敷料、贴膜覆盖穿刺部位,导管接输液皮条输 [0002] Current clinical common approach central venous puncture instrument central venous (right after the passage jugular vein as an example): 1) patient supine, head to the left, the puncture site routine disinfection, holes towels; 2) select the clavicular head after the upper edge of the clavicle at the two lateral finger puncture point, local anesthesia; 3) 5ml syringe with the puncture needle 7 connected to the sternoclavicular joint direction, the needle body holding horizontal position, syringe holding negative pressure; 4) Withdrawing the syringe to the dark red blood and smooth, it is determined in the jugular vein puncture needle, a needle or a fixed exit No. 7 No. 7 at the same time removing the syringe needle, the other connected with 18G needle along a 5ml syringe needle blue direction of the puncture needle 7, Withdrawing blood red to dark and smooth, it is determined in the jugular vein puncture needle via a syringe blue into the tail guidewire 250mm; 5) fixed to the guidewire exit 18G needle, through the guide wire expanded expandable tube inserted into a blood vessel puncture skin - puncture pathway; 6) fixed to the guidewire exit dilation tube, inserted central catheter guidewire 120mm; 7) secure the catheter, medical dressings, foil covering the puncture site, then the catheter infusion lose thong 液。 liquid.

[0003] 如上所述,使用目前临床常用的中心静脉穿刺器械行中心静脉穿刺,先用5ml注射器接7号针回抽到暗红色血液并通畅,确定穿刺针在颈内静脉(一次成功),退出7号针或固定7号针同时卸下注射器,只有当用5ml蓝针管注射器接18G钢针沿着7号针的方向穿刺,回抽到暗红色血液并通畅,确定穿刺针在颈内静脉时才标志穿刺成功(二次成功)。 [0003] As described above, commonly used in clinical use of central venous puncture instrument central venous line, the first pick 5ml syringe with needle 7 Withdrawing blood red to dark and smooth, determining venous needle (successful) in the neck, exit No. 7 needle or pin 7 is fixed at the same time removing the syringe, then only when the 18G needle of the syringe with the puncture needle tube 5ml blue No. 7 in the direction of the needle, Withdrawing blood red to dark and smooth, it is determined in the jugular vein puncture needle if successful puncture mark (secondary success). 由于:a) 7号针穿刺对血管造成的损伤刺激,会发生血管痉挛,b)如不退出7号针,虽然能起到固定血管的作用,但穿刺段血管会引起塌陷,c)反复穿刺造成穿刺部位血肿,导致血管移位、塌陷等原因,都给再次穿刺增加了困难。 Since: a) stimulation No. 7 needle injury caused by vascular, vasospasm occurs, b) does not exit as No. 7 needle, although fixed vessel can play a role, but will cause collapse of vascular puncture section, c) repeated puncture causing puncture site hematoma, a blood vessel leading to displacement, subsidence and other reasons, gave puncture again increased the difficulty. 因此再用5ml蓝色注射器接18G钢针穿刺时,常常不能一次就穿刺到目标静脉,反复穿刺势必增加损伤、增加并发症的发生率。 Thus then 5ml syringe connected to 18G needle piercing blue, are often unable to target vein puncture once, repeated puncture is bound to increase damage, increase the incidence of complications.
