Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a thrombolytic catheter fixing device. Background Art

[0002] Venous and arterial thrombosis caused by various reasons leads to lower limb swelling and ischemia, which usually causes obvious pain. At this time, catheter thrombolysis is chosen for treatment. This is a surgery that mainly places a catheter in the thrombus or near the thrombus site, and then injects a thrombolytic drug, such as urokinase, into the catheter, thereby ultimately dissolving the thrombus, allowing blood flow to resume normal operation, and can open the blood vessels. Since the thrombolytic catheter needs to be passed through the blood vessels to reach the designated thrombus site, the thrombolytic catheter is relatively long. Therefore, during the puncture thrombolysis process, a considerable length of the thrombolytic catheter usually falls outside, and since the thrombolysis lasts for a long time, the catheter that falls outside will cause inconvenience. Therefore, medical staff will wrap this section of the thrombolytic catheter outside into several circles, and then use a wire to bind the catheter circle to prevent the catheter circle from spreading. Therefore, there is currently a lack of a device that can store and fix the exposed thrombolytic catheter during catheter thrombolysis. Utility Model Content
