Abstract

The utility model provides a deep vein puncture catheterization auxiliary device and a deep vein puncture catheterization system. The clamping device is rotationally connected with the base and used for clamping or releasing the ultrasonic probe. The locking mechanism is arranged between the base and the clamping device and is used for limiting relative rotation between the clamping device and the base when locked. When deep vein puncture is performed, medical staff find a puncture point by using an ultrasonic probe. Then, after the ultrasonic probe is fixed on the clamping device, the base is supported on the human body, and the ultrasonic probe is aligned with the puncture point. At this time, medical staff can hold the base on the human body or fix the base on the human body by using a sterile medical film and the like, and the other hand or the two hands perform the puncturing operation. The base increases the contact area with the human body, so that the ultrasonic probe is more stable and displacement is effectively prevented. When the sterile medical film fixing base is used, two hands can be liberated, and the puncture effect is further improved.
