Description
Technical Field
The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to a reverse hooking skin expansion internal jugular vein auxiliary puncture device.
Background
Puncture under the real-time guidance of ultrasound can effectively ensure the success rate of internal jugular vein puncture, in particular to internal jugular vein with smaller internal diameter. However, the puncture under the real-time guidance of the ultrasound still has some problems, namely, the ultrasound probe can press the intravenous lumen, and the puncture needle tip can press the lumen, so that the vascular lumen is poor in filling and even the lumen collapses, especially under the condition of insufficient capacity of a patient, and the internal jugular vein puncture of the patient with insufficient capacity becomes a great clinical difficulty. In recent years, japanese scholars have proposed skin stretching methods (STM), which can achieve the purpose of stretching the skin above the internal jugular vein puncture point by stretching the skin around the puncture point towards the head side and the tail side, so as to increase the anterior-posterior diameter of the internal jugular vein lumen, thereby effectively avoiding collapse of the internal jugular vein lumen caused by compression of an ultrasonic probe or compression of a puncture needle, and even improving collapse of the internal jugular vein lumen of a patient with insufficient capacity. However, in the previous research, the skin stretching method is to stretch the skin through the medical adhesive tape, the adhesive tape fixing site and angle are not unified, the medical adhesive tape is fixed in advance before operation, once the puncture site or puncture angle is changed, the adhesive tape fixing position and angle are required to be adjusted again, and the skin stretching method is very inconvenient, so that a novel auxiliary puncture tool is required to be designed to solve the problems.
