Embodiment Construction

[0027] As detailed below, an anesthesia system according to an embodiment of the present invention is disclosed that includes a system that allows the user to mix oxygen and air in the anesthesia system to optionally adjust the concentration of oxygen delivered to the patient and reduce oxygen enrichment. The possibility of ignition of flammable materials in an environment attached to the gas control subsystem. Although the auxiliary gas control subsystem uses the same oxygen and gas sources used by the anesthesia machine and delivered to the patient through the main breathing circuit, the auxiliary gas control subsystem operates independently of the anesthesia machine so that Let either of them be in use while the other is not in use. Further, the auxiliary gas control subsystem can reduce or prevent the mutual contamination of the gas sources (such as oxygen and air) in the anesthesia machine when mixing the auxiliary gas, so that the entire system can continuously provide a...

Abstract

The invention provides an anaesthetizing system and a gas mixing method in the anaesthetizing system. The anaesthetizing system comprises a primary outlet and a secondary output, wherein the primary output and the secondary output work independent from each other; the primary output can be used for outputting first mixed gases and an anesthesia medium to a patient; and the secondary output can be used for outputting second mixed gases to the patient. A user can selectively mix oxygen and at least one other gas; thus, the second mixed gases provided to the secondary output have a desired flow rate and desired oxygen ratio. The second mixed gases passing through the secondary output are prevented from flowing into the anaesthetizing system again; thus, the possibility of polluting gases of the primary output can be reduced or eliminated.

Description

【Technical field】 [0001] The invention relates to the field of medical equipment, in particular to an anesthesia system and a gas mixing method in the anesthesia system. 【Background technique】 [0002] During surgery, the patient is anesthetized to reduce or eliminate pain during the procedure. A breathing system for administering an inhaled anesthetic medium may include, for example, an anesthesia machine for infusing a carrier gas with the anesthetic medium. The carrier gas is typically oxygen and nitrous oxide and / or air. Carrier and anesthetic medium gases from the anesthesia machine are fed into the main ventilator or anesthesia circuit for delivery to the patient during the patient's breathing. [0003] Oxygen sources can be used for anesthesia machines and auxiliary outputs directly to the patient. The auxiliary output may be provided to the patient via a nasal cannula for use in assisting in stabilizing the patient before and / or after surgery, or in other situatio...
