技术领域technical field
本实用新型属于医疗器械技术领域，具体地说，特别是涉及一种多腔隔离式电极导管。The utility model belongs to the technical field of medical equipment, in particular to a multi-cavity isolated electrode catheter.
背景技术Background technique
食道阻抗PH导管是多腔隔离式电极导管的一种，用于对患者食道内的多种参数进行实时监测，极导管上包括参考电极，PH传感器、阻抗传感器等传感器，使用时传感器将监测数据传送到数据记录仪。现有的食道阻抗PH导管为单腔管，漆包线穿在单腔管内，导管、阻抗环、锑电极通过一段一段的串联，然后用胶水密封连接。现有技术存在的不足在于：The esophageal impedance PH catheter is a kind of multi-lumen isolated electrode catheter, which is used for real-time monitoring of various parameters in the patient's esophagus. The electrode catheter includes reference electrodes, pH sensors, impedance sensors and other sensors. When used, the sensors will monitor data sent to the data logger. The existing esophageal impedance PH catheter is a single-lumen tube, and the enameled wire is passed through the single-lumen tube. The catheter, the impedance ring, and the antimony electrode are connected in series section by section, and then sealed and connected with glue. The deficiency that existing technology exists is:
1)导管、阻抗环、锑电极固定环的连接处是串联连接，连接处当出现粘胶不良时容易出现开裂漏水的风险。1) The joints of the catheter, the impedance ring, and the antimony electrode fixing ring are connected in series, and there is a risk of cracking and leakage when the joint is poorly glued.
2)导管内腔有多根漆包线，由于导管、阻抗环、锑电极固定环的内径很小，使穿漆包线的工艺很困难，且容易将漆包线的绝缘层破坏，产生短路风险。2) There are many enameled wires in the inner cavity of the catheter. Due to the small inner diameters of the catheter, the impedance ring, and the antimony electrode fixing ring, the process of threading the enameled wires is very difficult, and the insulation layer of the enameled wires is easily damaged, resulting in a risk of short circuit.
3)导管、阻抗环、锑电极粘接时容易溢胶到管道内部，将漆包线一起粘连，被粘连的漆包线活动余量被限制，当导管弯折角度大时有被拉断的风险。3) When the catheter, impedance ring, and antimony electrode are bonded, it is easy to overflow the glue into the inside of the pipe. If the enameled wire is bonded together, the movement margin of the bonded enameled wire is limited. When the bending angle of the catheter is large, there is a risk of being broken.
4)生产工艺复杂，工序多，生产效率低，成本高，并且产品的良品率难以保障。4) The production process is complicated, there are many processes, the production efficiency is low, the cost is high, and the yield rate of the product is difficult to guarantee.
