Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a large venous catheter fixing and adjusting component. Background Art

[0002] A large venous catheter is a medical device used to establish a pathway in a large vein. Unlike conventional peripheral venous catheters, the blood vessels into which large venous catheters are inserted are closer to the heart, which can provide greater flow and more stable blood flow. In clinical practice, catheters are mostly fixed by directly sticking them with medical tape. This fixing method can easily cause the catheter to slip when the patient moves. Therefore, the medical tape needs to be trimmed during sticking to ensure that the catheter does not slide relative to the patient during fixation. Traditional fixing methods cannot pad the interface of the venous catheter, which can easily injure the patient's skin. The venous catheter needs to be closed during clinical use. Traditional closing methods mostly use a stop clamp to clamp and close the catheter. During use, the stop clamp needs to be adjusted, so the stop clamp cannot be fixed on the outside of the patient's skin. During use, the stop clamp is prone to shaking, causing the venous catheter to move. Therefore, a large venous catheter fixing and adjustment component that can solve the above problems is needed.
