Problems solved by technology
[0003] In the patent document "CN210277898U A Self-Controlled Drug Administration Syringe for Nerve Blocking Under the Guidance of Ultrasound", the hydraulic piston rod moves downward to squeeze the briquetting block. When the seal moves to the bottom of the cavity, the liquid medicine passes through the cavity The liquid outlet channel opened on the inner wall of the chamber uses the pressure difference to deliver the drug to the infusion needle, and at the same time, the block set on the piston rod bounces to the side hole and enters the notch, so that the liquid inlet channel stops entering the liquid, and the piston rod is pressed by pressing the button. Reset, so that a single doctor can complete the quantitative anesthesia injection, thereby improving the work efficiency of the medical staff, simple and practical, but it is difficult to ensure the quantitative delivery of the drug solution, and it is easy to cause deviations in the amount of drug delivery during nerve block anesthesia injection. The effect of anesthesia will not only easily lead to nerve damage, but also lead to incomplete anesthesia. Although accurate puncture can be achieved under the guidance of ultrasound, medical staff may have vibration problems that may cause nerve damage and increase safety hazards. For patients under anesthesia, it is not only inconvenient to operate but also brings pain to the patient
There is still no ultrasound-guided nerve block anesthesia drug injection device with reasonable and reliable structure, stable drug injection function and quantitative injection function.

Description
technical field [0001] The invention relates to an ultrasonic-guided nerve block anesthesia drug injection device, in particular to an ultrasonic-guided nerve block anesthesia drug injection device, which belongs to the technical field of nerve block anesthesia drug injection application. Background technique [0002] Nerve block refers to the injection of local anesthetic around the nerve trunk, plexus, and ganglion to block its impulse conduction, so that the innervated area produces anesthesia. The nerve block only needs to be injected in one place to obtain a larger area of anesthesia. However, it may cause serious complications. Therefore, during the operation, you must be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, as well as the nearby blood vessels, organs and body cavities. Digital (toe) nerve trunk block, cervical plexus, brachial plexus block, and stellate ganglion and lumbar sympathetic ganglion block for d...
