Description

TECHNICAL FIELD

[0001] The application relates to the technical field of catheter fixing, in particular to a catheter fixing device. BACKGROUND

[0002] Cardiovascular surgery mainly refers to congenital heart disease, acquired heart disease, thoracic aortic disease and other cardiovascular diseases. Patients can go to the cardiovascular surgery department for treatment when the diseases occur. The treatment is one of the treatment methods for cardiovascular diseases.

[0003] During treatment, the catheter needs to be retained in the treatment site of the patient for a long time, but the general catheter is only fixed by a medical adhesive tape, and the stability of the fixing method is poor. The patient needs to pay attention to the state of the catheter at all times, which leads to a decline in the patient's mood. At the same time, the blood catheter connected with the catheter is exposed and is easy to be accidentally bent or squeezed, thereby reducing the treatment effect. In addition, the catheter infusion tube is long and has no special fixing device. In particular, the catheter is placed in the lower limbs, neck or groin of the patient and is inevitably moved. At this time, the catheter is easy to be displaced or even dropped. Therefore, a catheter fixing device is needed. CONTENT OF THE UTILITY MODEL
