Anesthesia waste gas extraction and purification equipment for anesthesia room

Abstract

The invention discloses anesthesia waste gas extraction and purification equipment for an anesthesia room, which comprises a casing, a control panel, a timer, a protective cover, an ultraviolet germicidal lamp, a card frame, a placement slot, an I filter element, an air suction pump, a branch pipe, a telescopic Bellows, oxygen generator, exhaust pipe, shroud, pull-out box, and II filter element, first of all, through the design of the suction mechanism, it can realize the continuous negative pressure suction of the suspended anesthesia exhaust gas in the anesthesia room, and cooperate with the built-in double set The filter layer can then achieve effective purification of anesthesia waste gas. Secondly, because of the two extraction methods of range type and partial pipeline type, it can be used in a large area indoors or around the patient's respiratory tract according to needs. Finally, it can also be used Oxygen supply is performed synchronously during the suction of anesthesia waste gas. In summary, it is convenient for application in an anesthesia room or an aerosol anesthesia environment.

Description

technical field [0001] The invention relates to the technical field of medical air purification equipment, in particular to an anesthesia waste gas extraction and purification equipment for an anesthesia room. Background technique [0002] Volatile anesthetics are a kind of halogenated compounds, which are closely related to chlorofluorocarbons that destroy the ozone layer. They are the main components that destroy the ozone layer and also cause ozone depletion. Metabolized by the patient, most of them are exhaled by the patient in the form of the prototype without any degradation, and the exhaled anesthetic gas gathers in the room. It is directly discharged into the anesthesia operating room, so it is not only easy to cause secondary inhalation by the patient, affecting the inhalation dose of anesthetic, but also easy to be inhaled by the medical staff in the anesthesia room, affecting the normal work of the medical staff, and easily causing dizziness, fatigue, and lack of ...

Problems solved by technology

[0002] Volatile anesthetics are a kind of halogenated compounds, which are closely related to chlorofluorocarbons that destroy the ozone layer. They are the main components that destroy the ozone layer and also cause ozone depletion. Metabolized by the patient, most of them are exhaled by the patient in the form of the prototype without any degradation, and the exhaled anesthetic gas gathers in the room. It is directly discharged into the anesthesia operating room, so it is not only easy to cause secondary inhalation by the patient, affecting the inhalation dose of anesthetic, but also easy to be inhaled by the medical staff in the anesthesia room, affecting the normal work of the medical staff, and easily causing dizziness, fatigue, and lack of energy in a short time However, due to occupational reasons, when medical staff are exposed to anesthesia exhaust gas for a long time, they are more prone to spontaneous abortion, infertility, birth defects, etc., which pose a threat to the health of medical staff.

[0003] According to the above, for the discharge of anesthesia waste gas, the central waste gas pumping method is often used clinically, and a simple discharge device is designed by using the Venturi principle, which sucks the air in the operating room and the waste gas discharged from the anesthesia machine into the central waste gas pipe. In the discharge, the cost of discharge is high, and the operating room must be equipped with a central air supply system, so it is difficult to popularize it.

In addition, China published a patent for anesthesia waste gas extraction device for anesthesia department, application number (201821215315.8), although it can achieve effective suction and purification of indoor anesthesia waste gas, it also has the following problems; Purification, it is impossible to strengthen the purification of the surrounding area of ​​​​the patient's respiratory tract. When the distance between the device and the patient is far away, it cannot achieve a good effect, and it is easy to cause the problem of secondary inhalation of the patient. 2. The built-in filter layer cannot be easily disassembled and replaced. When the equipment is used for a long time, because the filter layer cannot be replaced and cleaned, it not only leads to the breeding of germs, but also loses its purification effect because of the large amount of anesthetic halide inside. In view of this, it is necessary to design an anesthesia filter for anesthesia room. Exhaust gas extraction and purification equipment to solve the above problems
