Abstract

The invention relates to an anaesthetic and oxygen respiration dual-purpose mask. The anaesthetic and oxygen respiration dual-purpose mask comprises an external mask body and an internal mask body, wherein the external mask body can be combined with the nasal part of a user in a sealed mode to form a first cavity, and corresponding to the nasal position, the external mask body is provided with an air inlet communicated with the first cavity for connecting an anaesthetic gas supply device or an oxygen supply device; the internal mask body is detachably connected to the inner side of the external mask body and can be combined with the mouth part of the user to form a second cavity, also, the internal mask body is provided with an air outlet, which is communicated with the second cavity and penetrates the external mask body for communicating with a gas recovery device generating negative pressure. According to the anaesthetic and oxygen respiration dual-purpose mask, the air inlet of the external mask body can provide anaesthetic gas or oxygen for the nasal part, and the air outlet of the internal mask body can effectively recover gas exhaled from the mouth part, and meanwhile, the external mask body can independently serve as a common mask for different applications.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dual-purpose mask for anesthesia and oxygen inhalation. Background technique [0002] At present, when the patient is anesthetized during the operation, a mask is usually used to cover the patient's nose and mouth, and the other end is connected to the threaded tube of the anesthesia machine, and the anesthetic gas is delivered to the patient through the mask with good airtightness. Oxygen can also be delivered to the patient through the same mask when needed during or after surgery. [0003] However, this general-purpose mask does not take into account the removal of the anesthetic gas in the patient's respiratory tract, nor does it effectively recycle the anesthetic gas. Therefore, it is urgent to provide an anesthesia and oxygen inhalation dual-purpose mask that can simultaneously realize intraoperative anesthesia and gas recovery. Contents of the invention [00...
