Multifunctional electrocardio lead special wire and manufacturing method thereof

Abstract

The invention discloses a multifunctional electrocardio lead special wire and a manufacturing method thereof. The multifunctional electrocardio lead special wire comprises an electrocardio conductor formed by twisting a tin-copper foil wire conductor and a silver-plated copper foil wire conductor, and an FEP insulating layer is arranged on the outer surface of the electrocardio conductor to form an electrocardio inductor. The outer surface of the electrocardio inductor is sequentially coated with a conductive layer of an ethylene carbon resin component, a braided shielding layer of a tinned copper component and an outer sheath of an FEP component. One end of the five-core shielding lead wire is crimped with a human body connecting terminal, the other end of the five-core shielding lead wire is connected with the tail end of one core wire of the five-core shielding lead wire through the chip circuit board, and a series circuit of a gas discharger and a chip resistor in the chip circuitboard is insulated and shielded. The other end of the five-core shielding lead wire is connected with a plug used for electrocardiogram equipment, and magnetic ring anti-interference processing is adopted. The special wire has the advantages of bending resistance, tension resistance, high temperature resistance, good defibrillation effect, strong electrostatic protection, good shielding effect andthe like, is not interfered by the outside when transmitting physiological signals of a patient, and is accurate in signal transmission.

Description

technical field [0001] The invention relates to medical electronic device accessories, consumables and processes, in particular to a multi-functional dedicated line for electrocardiographic leads and a manufacturing method thereof. Background technique [0002] A multi-functional ECG lead wire is a special wire for ECG monitoring equipment, used to connect monitoring probes and various ECG monitoring equipment (ECG, monitors, etc.), after the probe collects the patient's physiological signals, it passes through multiple Function The special line for ECG leads transmits bioelectrical signals such as ECG signals, EMG signals, brain waves and nervous system signals to ECG monitoring equipment for real-time monitoring of seriously ill patients. Existing ECG lead lines usually contain human body connection terminals , Several ECG lead wires, relay boxes, circular multi-core lead wires and plugs connected to ECG equipment. There are usually certain shielding measures in the lead w...

AI Technical Summary

Problems solved by technology

However, the existing ECG lead wires have poor shielding effect, weak tensile and bending resistance; conductors are usually made of bare copper components, which are easy to cause oxidation, and the terminals connected to the human body are usually made by welding, which is very easy to cause solder joints in frequent use Falling off and breaking of the connection will cause the internal core wire of the lead wire to lose its signal conduction function, which cannot meet the frequent clinical use in medicine

Multiple ECG lead wires can be used at the same time to measure human body signals from multiple parts of the human body. The relay box of multiple ECG lead wires acts as a splitter, and sometimes accommodates components such as resistors and magnetic rings, but the process requirements High, small capacity makes the relay box have few functions, the quality cannot be guaranteed, and it does not have a good effect on defibrillation, anti-static, high temperature resistance, etc. At the same time, the relay box is ignored as a part of the lead wire and the additional shielding layer , so that the lead wire cannot completely shield the interference of external signals, so that the accuracy of measuring human body signals is poor

Existing ECG lead wires lack overcurrent protection and static electricity treatment, which can easily cause damage to the core wire and generate an electrostatic magnetic field, affecting its function
