Embodiment Construction

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0063] A catheter tip positioning method for positioning a catheter in a catheterization procedure at the heart based on an electrocardiogram signal.

[0064] It should be noted that the systole and diastole constitute a cardiac cycle, and the electrocardiographic signals of a cardiac cycle generally include P wave, PR segment, QRS wave group, ST segment, T wave and so on. Among them, the P wave, the electrical excitation of the normal heart starts from the sinoatrial node. Since the sinoatrial node is located at the junction of the right atrium and the superior vena cava, the excitation of the sino...

Abstract

The invention relates to a method and a system for positioning the tail end of a catheter, and the catheter in the puncture catheterization is positioned in the heart position on the basis of the ECG(electrocardiograph) signals. The method for positioning the tail end of the catheter comprises the steps that body surface ECG signals and in vivo ECG signals are collected simultaneously; in the preset time interval, position information of a body surface QRS wave group is obtained according to the body surface ECG signals; the current P wave amplitude value of a complete in vivo P-QRS wave in the vivo ECG signals is positioned and obtained according to the position information of the body surface QRS wave group; the position information of the catheter tail end is obtained according to themapping relation of the ratio of the current P wave amplitude value and a preset P wave amplitude value and the preset position information; the complete in vivo P-QRS wave and the position information of the catheter tail end are displayed. According to the method, the operation is convenient, the display is visual, the practicability and the success rate of the puncture operation are improved greatly, in the use process, other auxiliary personnel is not required, and no harm is caused to the human body.

Description

technical field [0001] The invention relates to the technical field of intravascular device positioning, in particular to a catheter end positioning method and system. Background technique [0002] Peripherally Inserted Central Venous Catheters (PICC) is a treatment technique that inserts a catheter into a vessel and leaves an opening outside the body. The superior vena cava is close to the junction of the right atrium, so that it can quickly enter the blood circulation system and the location information close to the heart. The key to puncture catheterization is to enable medical staff to find the position information of the catheter end in a timely and accurate manner. If the catheter puncture position information is too shallow or too deep, it will cause thrombosis, phlebitis, vein wall corrosion, venous perforation, myocardial perforation and other complications. disease. [0003] In order to achieve accurate positioning of the catheter during puncture in the body, aux...
