Description

Fixing device for ultrasonic-assisted midline catheter placement Technical Field The utility model relates to the technical field of medical appliances, in particular to a fixing device for ultrasonic-assisted midline catheter catheterization. Background Midline catheter placement is a medical procedure in which a midline catheter is placed through a peripheral vein, such as a vein at the fossa of the elbow. The main purpose is to provide a stable and safe venous access for the patient, and when the central line catheter puncture technology is used in clinic, the ultrasonic probe is fixed above the blood vessel of the patient for guiding, and the other hand is used for performing puncture operation through the central line catheter. At present, when medical staff carries out central line catheter placement, a hand-held ultrasonic probe is required to be fixed above a blood vessel of a patient for guiding, and the other hand is required to carry out puncture operation, so that the medical staff cannot fix a skin blood vessel by a third hand, the central line catheter placement cannot be independently completed, meanwhile, the central line catheter placement is a strict aseptic operation technology, certain aseptic requirements are met for used articles, the fixing device of the ultrasonic probe is mainly a fixing frame, and the ultrasonic probe has a large volume and a complex structure, and even if the ultrasonic probe is used for wiping and sterilizing by using sterilizing liquid, a region with the sterilization not up to standard also exists. Disclosure of utility model The utility model aims to solve the technical problems that medical staff cannot independently complete the central line catheter puncture operation, the fixing device is large in size and complex in structure, and the situation that disinfection does not reach standards easily occurs.
