A simple central venous puncture detector.
During central venous cannulation, percutaneous venous puncture is performed blindly using a variety of surface landmarks on the body for different puncture sites. To avoid vessel transfixion and injury to adjacent structures, the earliest detection of venous puncture is essential. A simple central venous puncture detector is described, which not only efficiently detects entry of the needle into the vein but also prevents air embolism and blood spillage.
