Gas suction device

Abstract

The invention provides a gas suction device, which comprises a cover body and a drainage assembly, the cover body is bent to form a containing cavity, the drainage assembly is contained in the containing cavity, the drainage assembly comprises a main body, a mouth inhalation part and a snuffing part, the mouth inhalation part and the snuffing part are communicated with the main body, the mouth inhalation part can stretch out and draw back and / or bend relative to the main body, the snuffing part can stretch out and draw back and / or bend relative to the main body, and two air outlet parts communicated with the snuffing part are arranged on the snuffing part; when a user wears and uses the gas suction device, the position of the mouth inhalation part is adjusted to enable the mouth inhalation part to be located near the mouth or in the mouth, the position of the snuffing part is adjusted to enable the two gas outlet parts to be located below the two nares or in the two nares respectively, gas provided by an external machine is directly inhaled by the user through the mouth inhalation part and the gas outlet parts, and the concentration of the gas cannot be reduced.

Description

technical field [0001] The invention relates to the field of medical accessories, in particular to a gas inhalation device. Background technique [0002] At present, the treatment method of gas inhalation (assisted breathing) is widely used in hospitals and families. The treatment process is: connect the machine (such as: ventilator) with the medical mask, the user wears the medical mask, and the medical mask is closely attached to the user's face. To cover the mouth and nose of the user, the machine first passes the A gas into the medical mask, the user inhales the A gas by inhaling, and exhales the B gas into the medical mask; the following problems exist in the use of the medical mask: the A gas provided by the machine (such as : Oxygen), mixed with the B gas exhaled by the user {B gas includes nitrogen, oxygen, carbon dioxide and a small amount of inert gas (argon, krypton, xenon, neon, helium, etc.)} mixed in the medical mask, the mixture will cause A gas Concentration...

[0002] At present, the treatment method of gas inhalation (assisted breathing) is widely used in hospitals and families. The treatment process is: connect the machine (such as: ventilator) with the medical mask, the user wears the medical mask, and the medical mask is closely attached to the user's face. To cover the mouth and nose of the user, the machine first passes the A gas into the medical mask, the user inhales the A gas by inhaling, and exhales the B gas into the medical mask; the following problems exist in the use of the medical mask: the A gas provided by the machine (such as : Oxygen), mixed with the B gas exhaled by the user {B gas includes nitrogen, oxygen, carbon dioxide and a small amount of inert gas (argon, krypton, xenon, neon, helium, etc.)} mixed in the medical mask, the mixture will cause A gas Concentration decreases, resulting in decreased therapeutic effect

[0004] 1. If the small holes are made too large or too many, the A gas provided by the machine will escape more and fail to reach the preset concentration;

[0005] 2. If the small hole is made too small, the gas B exhaled by the user will not be discharged smoothly, and it will accumulate in the medical mask and mix with gas A, resulting in a decrease in the concentration of gas A. At the same time, if the small hole is made too small, Also increases the air pressure inside the medical mask, making the user uncomfortable
