Abstract

The invention provides a foot pump type injection pump special for nerve block under ultrasonic guidance, which comprises foot pumps and an injection structure, the injection structure drives a needle cylinder to push or withdraw through the cooperation of a sealing cavity and hydraulic pressure, the number of the foot pumps is two, the two foot pumps respectively pressurize and depressurize the injection structure, and the two foot pumps correspond to the push and withdraw actions of an injector; according to the device, an assistant is not needed, operation is completed by one person independently, ultrasonic nerve positioning and puncture operation are carried out through the two hands respectively, meanwhile, liquid medicine injection and withdrawing are carried out through the action that the foot treads or lifts the pedal, and the work content of a second person is omitted; the size is small, the cost is low, and electronic equipment is not needed.

Description

technical field [0001] The invention mainly relates to the field of medical equipment, in particular to a special foot-pump injection pump for nerve block under the guidance of ultrasound. Background technique [0002] With the development of visualization technology, it has become a new requirement and a new trend for anesthesiologists in the new era to be able to skillfully use ultrasound and apply it to various blood vessel punctures, nerve blocks, or bedside rapid diagnosis. In recent years, under the influence of precision medicine and personalized treatment plans, various nerve blocks under the guidance of ultrasound have become a common technique in anesthesiology departments of major hospitals. [0003] However, the operation of this technology generally requires two people. The main operator operates the ultrasonic probe with one hand to explore the nerve to be blocked, and the other hand performs the puncture operation. Once the needle tip reaches the target drug i...
