Description

High-precision anesthetic gas flow regulation and control system Technical Field The utility model relates to the technical field of medical instruments, in particular to a high-precision anesthetic gas flow regulating and controlling system. Background Medical gas anesthesia refers to that a patient enters an unconscious state by inhaling a gas mixture containing an anesthetic so as to perform surgery or other medical procedures, and the anesthesia method is one of the common anesthesia technologies in modern medicine and has the advantages of quick effect, good controllability and the like; when anesthesia is carried out, various gases are required to be transported and mixed and then can be used as anesthetic gases, and common anesthetic gases comprise oxygen, air and one or more inhalation anesthetics (such as isoflurane, sevoflurane and the like), laughing gas (nitrous oxide) is sometimes used as an aid, and the gases need to be precisely controlled in the transportation process; the conveying of the gas is shown as the application number CN201820397597.1 and a concentration-adjusting type anesthesia device in anesthesia department, the proportion of oxygen and anesthetic gas is controlled by a controller, so that the concentration adjustment of anesthesia is conveniently realized, the heating plate and the spherical volume device accelerate the movement of gas molecules, the uniform mixing of oxygen and anesthetic gas is conveniently realized (uniform precision is improved, anesthesia effect can be improved, side effect is reduced), and the anesthesia effect is facilitated: However, this way of improving the uniformity of the gas mixture requires heating, which is less safe and also has the disadvantage of energy consumption. Disclosure of utility model The utility model aims to solve the technical problems and provides a high-precision anesthetic gas flow regulating and controlling system. The utility model adopts the following technical scheme for realizing the purposes: The utility model provides a high-precision anesthetic gas flow regulation and control system, which comprises; A plurality of sets of gas supply mechanisms each of which separately supplies a gas for generating anesthetic gas; The air supply mechanism comprises a first through pipe, and a flowmeter and a proportional valve which are communicated and fixed between the first through pipes in sequence; The gas delivery mechanisms of the multiple groups are different from each other, and the gas delivery mechanisms of the multiple groups are correspondingly provided with multiple groups of first through pipes; The coarse mixing assembly is connected with the discharge ends of the plurality of groups of first through pipes and is used for primarily mixing a plurality of gases to form anesthetic gases; the gas distribution assembly is connected with the discharge end of the coarse mixing assembly and is used for uniformly distributing the primarily mixed anesthetic gas; and the fine mixing assembly is connected with the discharge end of the gas distribution assembly and is used for discharging the uniformly-distributed mixed anesthetic gas after being mixed again. As a preferable technical scheme of the utility model, the coarse mixing assembly comprises a first column shell, a first collecting hopper and a first discharge pipe which are communicated and fixed in sequence, wherein the discharge ends of a plurality of groups of first through pipes are uniformly distributed at the periphery of the first column shell and communicated and fixed.
