Guide wire connection device used for electrocardiographic positioning during PICC cathetering

Abstract

The invention discloses a guide wire connection device used for electrocardiographic positioning during PICC cathetering, and relates to the technical field of medical treatment. The guide wire connection device comprises a connection head, wherein the left side output end of the connection head is fixedly connected with a connecting pipe. The guide wire connection device used for the electrocardiographic positioning during the PICC cathetering can be suitable for any catheter through a Luer joint thread ring and comprises a front end three-way valve type or front-end opening type catheter; during the electrocardiographic positioning, the tail end of the guide wire is handed to an assistant, so that a button on a round seat is connected with an electrocardiographic monitoring lead wire; then, the connection head, an anti-blood-returning clip, a connection column and the connecting pipe are cooperated with a syringe to push and inject normal saline; therefore, the syringe is cooperatedto push and inject the normal saline to establish continuous and stable electric conduction current of guide wire-saline-blood so as to obtain stable and continuous endocardial electrocardiographic lead; and therefore, the problem that since the front end of the front-end three-way valve is sealed, an electrocardiosignal detected by an electrocardiogram monitor is very weak can be emphatically solved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a guide wire connection device used for electrocardiographic positioning during PICC tube placement. Background technique [0002] Peripherally Inserted Central Catheter (PICC) refers to a catheter inserted through a peripheral vein with the tip located in the superior vena cava or inferior vena cava. Studies have shown that the position of the tip of the PICC catheter is closely related to the complications of patients after catheterization. The American Society of Intravenous Nurses recommended in the 2016 version of the INS guidelines that the tip of the PICC catheter should be located in the lower segment of the superior vena cava or near the junction of the superior vena cava and the right atrium. place. At present, the X-ray positioning method is used as the "gold standard" for PICC tip positioning diagnosis in China, but the X-ray positioning method cannot be located in ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a guide wire connection device for ECG positioning when PICC catheterization is performed, which solves the problem that the ECG signal detected by the ECG monitor is very weak compared to external interference signals. Its amplitude is very small leading to the problem of being easily disturbed
