Technical Field
[0001] The utility model relates to the technical field of arterial sheath tubes, in particular to a catheter connection auxiliary device for arterial sheath tubes. Background Art
[0002] With the change of the concept of interventional treatment for liver cancer, the clinical application of transcatheter hepatic arterial infusion chemotherapy is becoming more and more common. Hepatic arterial catheterization perfusion chemotherapy has two approaches: femoral artery access and radial artery access. In interventional treatment, the use of a sheath can often facilitate the treatment process. The front end of the sheath is inserted into the blood vessel and then placed therein, and the tail end of the sheath is an open end, through which a guide wire, catheter, etc. can be inserted.
[0003] Currently, when performing arterial infusion chemotherapy through the femoral artery, a transparent patch or a disposable patch is generally used for simple fixation. However, this type of fixation method has the risk of the sheath falling off. Once pulled out, it will cause heavy bleeding and endanger the patient's personal safety. For this reason, we propose a catheter connection auxiliary device for the arterial sheath. Utility Model Content
