Method for manufacturing temporary heart pacing electrode catheter

Abstract

The invention relates to a method for manufacturing a temporary heart pacing electrode catheter. The method comprises the following steps: firstly, closely winding multiple steel wires in parallel into a spring-like shape; coating the center electrode of the spring-like shape with a paste resin insulation layer to be subject to the thermoplasticizing treatment; winding three soft electrodes at the outside of the treated center electrode; coating with polyurethane catheters, respectively leading out each soft electrode from the wall side holes of the polyurethane catheters; wrapping the end parts of the soft electrodes with metal rings to respectively form a cathode and an anode, and fixing with fixing wings in the groove which is adjacent to the head of the styloid metal electrode; and finally, respectively connecting the cathode and the cathode of each electrode with wires of different colors by a tail connection block. The invention has the advantages of simple manufacture and low cost, and completely adoption of domestic materials for the production of the electrode, the reduction of medical treatment burden for patients, t the wide application range and easy popularization.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a method for making a temporary cardiac pacing electrode catheter. Background technique [0002] Temporary cardiac pacing is widely used, such as severe bradycardia caused by acute myocardial infarction, severe myocarditis, electrolyte imbalance, drug poisoning, anesthesia, surgery, electric shock, renal failure, rapid rescue of patients during cardiac arrest, and cardiac rhythm and areas of life support. At present, there are many forms of electrodes for temporary cardiac pacemakers, such as unipolar implantable cardiac pacemaker electrodes, ordinary bipolar endocardial electrodes and floating electrode catheters. Although cardiac pacing electrodes save the lives of many heart disease patients and improve their It is the most direct and effective way for its work, living ability and quality, but due to the limitations or deficiencies in some aspects of the various manufacturing m...

At present, there are many forms of electrodes for temporary cardiac pacemakers, such as unipolar implantable cardiac pacemaker electrodes, ordinary bipolar endocardial electrodes and floating electrode catheters. Although cardiac pacing electrodes save the lives of many heart disease patients and improve their It is the most direct and effective way for its work, living ability and quality, but due to the limitations or deficiencies in some aspects of the various manufacturing methods of cardiac pacing electrodes currently used, the manufacturing cost is relatively high and the price is expensive; The catheter is too hard, which can easily lead to myocardial perforation; the operation in clinical application is complicated and time-consuming, which increases the workload of medical staff; patient discomfort
