The incorrect statement about the use of vascular catheter add-on devices is C. The heparin cap or needleless connector attached to the PICC, CVC, and PORT should be replaced at least once every 3 days E.
A vascular catheter add-on device is a common medical device that is widely used in clinical medical and surgical treatments. It is an adjunctive device designed to ameliorate the difficulty and discomfort of vascular catheter insertion and to minimize operative risks and complications. A vascular catheter add-on device generally consists of a guiding needle, a catheter and a dilator.
Before use, the catheter is first entered into the body through a hypodermic needle, and punctured into the blood vessel sequentially, and then the catheter is entered through the needle after determining the exact position, and then dilated with the dilator after the catheter reaches the predetermined site. In this way, the catheter in the blood vessel can be inserted smoothly and accurate data and information can be obtained during treatment and examination.
The vascular catheter add-on device has the following advantages over conventional vascular catheter insertion methods. First, the vascular catheter add-on device can improve the problem of difficult intubation. In many cases, traditional intubation methods require a great deal of skill and experience to accurately insert the catheter into place.
The vascular catheter add-on device, however, can insert the catheter more consistently and accurately through the action of the guide pin and dilator, reducing the risk of inaccurate positioning.
Second, vascular catheter add-on devices have a lower complication rate. Traditional intubation methods have the potential for over-penetration, infection, and bleeding, which can easily lead to complications. The use of vascular catheterization add-on devices can avoid these problems, thus effectively improving the safety and success rate of surgical treatment.
In addition, the vascular catheter add-on device is characterized by its rapid, reusable and high catheter flow rate, which provides convenience and support for clinical medical and surgical treatment.
In conclusion, the vascular catheter add-on device is an advanced medical device that has a significant role in improving the accuracy and safety of vascular catheter insertion. In the future development, it will continue to play an active role in clinical medical and surgical treatment, bringing more benefits to patients' treatment and recovery.
