[0002] ECMO refers to extracorporeal membrane oxygenation, which is mainly used to provide continuous extracorporeal respiration and circulation to patients with cardiopulmonary failure in order to maintain their lives. ECMO mainly includes intravascular cannula, connecting tubes, power pumps (artificial hearts), oxygenators (artificial lungs), oxygen supply tubes, detection systems and other parts. When in use, the ECMO catheter is often established with adhesive tape to establish common catheterization sites, such as the internal jugular vein, femoral vein and other deep veins. When the ECMO catheter is actually used, the adhesive tape that fixes the ECMO catheter is easily contaminated by water or external impurities and debonded after long-term use. As a result, the ECMO catheter is prone to falling off or loosening when the human body is moving, which reduces the stability of the ECMO catheter and is very unfavorable for the treatment of patients.

[0003] In summary, the utility model provides a fixing device for an ECMO catheter to solve the above problems. Utility Model Content

[0030] Specific working principle:

[0031] First, place the connecting belt 1 at the position on the human body where the catheter needs to be fixed, then pull the right end of the connecting belt 1, the connecting belt 1 drives the second Velcro 3 to move to one side, so that the bottom of the second Velcro 3 contacts the top of the first Velcro 2, and then the second Velcro 3 and the first Velcro 2 are bonded to complete the fixation with the human body, then pull the movable rod 7, the movable rod 7 drives the positioning frame 5 to move upward, the positioning frame 5 drives the spring 8 to move upward, so that the spring 8 is compressed and deformed, and at the same time the catheter is placed in the inner cavity of the plastic seat 4, and then the catheter is limited, and then released. The movable rod 7 drives the positioning frame 5 to move downward through the reset elastic force of the spring 8, so that the positioning frame 5 contacts the catheter. At the same time, the positioning frame 5 can press the catheter together with the reset elastic force of the spring 8 to complete the positioning of the catheter, effectively ensuring the stability of the catheter. Then, by pushing the sliding rod 10, the sliding rod 10 is forced to move to one side, and the sliding rod 10 is limited by the limiting seat 9, so that the sliding rod 10 can drive the first magnet 12 to stably slide to the inner cavity of the positioning hole 11 and contact the second magnet 13 to complete the connection, thereby positioning the movable rod 7, effectively alleviating the movable rod 7 is susceptible to the elastic force of the spring 8 and moves, which further improves the stability of the catheter positioning. When the catheter needs to be disassembled, the slide bar 10 is first pulled, and the slide bar 10 drives the first magnet 12 to move to one side, so that the first magnet 12 and the second magnet 13 are separated from the magnetic connection. At the same time, the slide bar 10 is separated from the inner cavity of the positioning hole 11, and the positioning of the movable rod 7 is released. Then, the movable rod 7 is pulled, and the movable rod 7 drives the positioning frame 5 to move upward, so that the positioning frame 5 is separated from the contact with the catheter, and then the catheter can be pulled to remove the catheter from the inner cavity of the plastic seat 4, completing the catheter positioning. When the connecting belt 1 needs to be removed from the human body, the right end connecting belt 1 is pulled, and the connecting belt 1 is forced to move upward to make the second Velcro 3 and the first Velcro 2 disengage, thereby releasing the connection between the connecting belt 1 and the human body, and completing the disassembly. This solves the problem in the prior art that the adhesive tape for fixing the ECMO catheter is easily contaminated by water or external impurities and debonded after long-term use, and the ECMO catheter is prone to falling off or loosening when the human body is moving, thereby reducing the stability of the ECMO catheter, which is very unfavorable for the treatment of patients.
