Description
Technical Field
The invention relates to the field of waste gas treatment, in particular to an anesthetic waste gas pumping device for an anesthetic department.
Background
The inhalation anesthetic is a volatile liquid or gas, enters a human body through a respiratory tract to play a role of anaesthesia from shallow to deep, has the characteristics of strong anaesthesia function, high controllability and the like, and has a leading position in general anaesthesia and the maintenance process of anaesthesia. The first general anesthetics (1842) used in surgery were diethyl ether, nitrous oxide and chloroform. The anesthesia period of the ether is clear, the control is easy, and the ether has good analgesic and muscle relaxation effects. But the traditional Chinese medicine composition is rarely used due to the defects of flammability, explosiveness, bad smell, stimulation to respiratory tract, increase of gland secretion, easy occurrence of accidents and the like. Nitrous oxide has the advantages of good analgesic effect, low toxicity and the like, but has weak anesthetic effect and is often used together with other general anesthetics. Chloroform is rejected due to its high toxicity. In order to overcome the defects of flammability, explosiveness, high toxicity of chloroform and the like of the narcotic ether, other better inhalation narcotics are searched. Introduction of halogen atoms into hydrocarbon and ether molecules reduces flammability and increases anesthetic action, but increases toxicity. Later, the introduction of fluorine atoms was found to be less toxic than the introduction of other halogen atoms, and consequently halothane, enflurane, isoflurane, sevoflurane, desflurane, etc., which are of value in applications were discovered in succession.
The inhaled anesthetic gas is not completely absorbed by the human body, part of the inhaled anesthetic gas is discharged along with the breathing of the patient, and the discharged gas is anesthetic waste gas; halide narcotics can cause ozone layer depletion, accelerate global warming, and are potentially harmful to the global environment. Less than 5% of the inhalation anesthetic drugs are metabolized by the patient, and most are exhaled by the patient in the prototype form with little degradation. In addition, abortion, infertility, etc. may occur to the exposed population in the anesthetic exhaust gas. Thus, concerns about the potential hazards of anesthetic waste gases are increasing. Volatile anesthetics are halides that are closely associated with ozone-depleting chlorofluorocarbons, which are the major ozone-depleting component, and also cause ozone-depleting operating room personnel to be harmed by prolonged exposure to anesthetic gases, especially in the absence of gas scavenging systems where exhaust gas exposure has a greater impact on occupational health. Health effects that occupational exposure may cause are: fatigue, irritability, headache, abnormal liver function, kidney function, hematopoietic system, and behavioral changes. Exposed to anesthetic waste gas, particularly nitric oxide, spontaneous abortion, infertility, birth defects and the like are easy to occur.
The discharge of anesthetic waste gases in the operating room seriously endangers the health of medical staff; the extraction and purification mode that current anesthesia waste gas extraction device adopted purifies and discharges in will anesthesia waste gas suction device through the negative pressure, and its mode that produces the negative pressure is negative pressure pump or fan, and these two kinds of equipment all can produce great noise when using, have solved the problem of anesthesia waste gas but have brought the problem of noise pollution yet, and noise pollution can influence medical staff's operation in this type of environment especially in the operating room, also probably reduces the anesthesia effect.
