SYSTEMS AND METHODS FOR BREACHING A STERILE FIELD FOR INTRAVASCULAR PLACEMENT OF A CATHETER |
摘要 |
An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. Various means for establishing a conductive pathway between a sterile field of the patient and a non-sterile field to enable passage of ECG signals from the catheter to the tip location sensor are also disclosed. |
