Abstract
Description
Technical Field
[0001] The utility model relates to the medical field, in particular to a fixing device for a thrombolytic catheter. Background Art
[0002] A thrombolytic catheter is a medical device used to treat vascular thrombosis. There are two main types: catheter-directed thrombolysis (CDT) and systemic thrombolysis. Catheter-directed thrombolysis (CDT) involves inserting a thrombolytic catheter directly into a venous thrombus, allowing the thrombolytic drug to act directly on the thrombus. The advantage is that the drug can act quickly and directly on the embolic site, reducing the time it takes for the drug to reach the lesion site, increasing the local concentration of the drug, and achieving the best thrombolytic effect in the shortest time. It also has a short treatment time and few complications, making it the preferred thrombolytic method in clinical practice.
[0003] Thrombolytic catheters play an important role in the treatment of thrombotic diseases. Thrombolytic catheters need to be fixed in a suitable position during use. However, for patients with lower limb venous thrombosis, catheterization and thrombolytic therapy are mostly fixed with dressings or 3M directly. The movement of patients in bed may cause the catheter to shift, resulting in problems such as inconvenient operation and poor stability of the thrombolytic catheter fixing device, which affects the efficiency and effectiveness of the treatment. Therefore, we propose a thrombolytic catheter fixing device to solve the above problems. Utility Model Content
