Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a fixer for central venous catheterization. Background Art
[0002] Central venous catheterization is an important measure for perioperative hemodynamic monitoring, infusion of various drugs and nutrition in critical and severe surgery. It is widely used in clinical practice, especially in patients undergoing extracorporeal circulation heart surgery. Central venous catheters are a practical and reliable monitoring and treatment method for rapid infusion, monitoring, nutritional support, etc. during emergency and critical care rescue due to their advantages such as long retention time, wide range of infusion types, and simple methods.
[0003] The existing central venous catheter is generally fixed by wrapping it with sterile gauze or a treatment towel. This fixation method has a poor stabilizing effect on the central venous catheter, and after being torn open for observation many times, the viscosity of the sterile gauze is easily reduced, and it is easy to fall off, which reduces the effect of use. Therefore, we propose a fixator for central venous catheter. Utility Model Content

The connection is fixed by a first fixing bolt 5, a limiting hole 13 is fixedly provided on the surface of the connecting disk 12, a limiting rod 14 is slidably connected inside the limiting hole 13, a pressure block 15 is fixedly connected to one end of the limiting rod 14, a slider 16 is slidably connected inside the limiting hole 13, one side of the slider 16 is fixedly connected to one side of the limiting rod 14, a spring 17 is fixedly connected to the bottom of the slider 16, the bottom end of the spring 17 is fixedly connected to the inner bottom of the limiting hole 13, and a through hole 6 is fixedly provided on the surfaces of the fixing plate 3, the connecting disk 12, and the fixing disk 4, and the pressure block 15 is arranged on the inner side of the through hole 6.
[0022] In this embodiment, when in use, one end of the central venous catheter is inserted from the inside of the perforation 6, so that one side of the central venous catheter is arranged in the middle of the plurality of pressing blocks 15. When the end of the central venous catheter is inserted into the patient's body, the release paper 2 at the bottom of the dressing 1 is torn off, so that the bottom of the dressing 1 and the patient's body surface are bonded and fixed, and then the turntable 7 is manually twisted.
