本实用新型涉及医疗器械技术领域，尤其涉及中心静脉改良穿刺针。The utility model relates to the technical field of medical instruments, in particular to an improved central vein puncture needle.
背景技术Background technique
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，导管接输液皮条输液。At present, the commonly used methods of central venous puncture with central venous puncture equipment (example for puncture of the right internal jugular vein from the posterior approach): 1) The patient is placed in a supine position with the head tilted to the left, the puncture site is routinely disinfected, and a drape is laid; 2) ) Select the posterior edge of the clavicular head of the sternocleidomastoid muscle and the two transverse fingers above the clavicle as the puncture point, and perform local anesthesia; 3) Use a 5ml syringe to connect a No. 4) The syringe draws back dark red blood and is unobstructed. Make sure that the puncture needle is in the internal jugular vein, withdraw or fix the No. 7 needle and remove the syringe at the same time, and connect the 18G steel needle with a 5ml blue needle syringe along the No. 7 needle. Puncture in the direction of the needle, draw dark red blood back and unobstructed, confirm that the puncture needle is in the internal jugular vein, insert a guide wire 250 mm through the tail of the blue syringe; 5) fix the guide wire, withdraw the 18G steel needle, and insert the dilation Tube dilation of the puncture point from the skin to the blood vessel—the puncture route; 6) Fix the guide wire, exit the dilation tube, and insert a 120mm central venous catheter through the guide wire; 7) Fix the catheter, cover the puncture site with medical dressings and films, and connect the catheter to the infusion thong for infusion .
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，必须先用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)。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。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。鉴于以上缺陷，实有必要设计中心静脉改良穿刺针。As mentioned above, when using the central venous puncture instrument commonly used in clinical practice for central venous puncture, you must first use a 5ml syringe connected to a No. No. 7 needle or fixed No. 7 needle and unload the syringe at the same time, only when the 5ml blue needle syringe is connected to the 18G steel needle to puncture along the direction of No. Mark puncture success (secondary success). Due to: a) Vasospasm will occur due to the damage and stimulation of blood vessels caused by puncture with the No. Hematoma at the puncture site, blood vessel displacement, collapse and other reasons all increase the difficulty of re-puncture. Therefore, when punctured with a 5ml blue syringe connected to an 18G steel needle, it is often impossible to puncture the target vein at one time, and repeated punctures will inevitably increase damage and increase the incidence of complications. In view of the above defects, it is necessary to design an improved central venous puncture needle.
