Oxygen humidifying liquid bag and oxygen humidifying device

Abstract

Disclosed are an oxygen humidifying liquid bag and an oxygen humidifying device. The oxygen humidifying liquid bag comprises a bag body and a mouth tube component; the mouth tube component is connected to the bag body in a sealed mode; the mouth tube component is provided with an internal channel communicating with an inner cavity of the humidifying liquid bag; an inner cavity of the humidifying liquid bag is used for containing humidifying liquid; the internal channel of the mouth tube component is provided with a humidifying liquid outlet; the humidifying liquid bag further comprises a slender humidifying liquid conveying channel extending to the lower portion of the humidifying liquid bag body; the upper portion of the humidifying liquid conveying channel communicates with the internal channel of the mouth tube component; the humidifying liquid conveying channel is provided with at least one lower opening; the lower opening of the humidifying liquid conveying channel communicates with the inner cavity of the humidifying liquid bag; the oxygen humidifying device comprises a container with an oxygen inlet structure and an oxygen outlet structure; a part or all of an inner cavity of the container can be used for humidifying oxygen; the oxygen humidifying device further comprises a humidifying liquid pump and an oxygen humidifying liquid bag connecting structure; humidifying liquid is sucked into the humidifying liquid pump through the humidifying liquid outlet via the connecting structure; and the humidifying liquid enters the inner cavity of the container through a pump outlet structure of the humidifying liquid pump.

Description

technical field [0001] The invention relates to an oxygen humidification liquid bag and an oxygen humidification device, belonging to the technical field of medical instruments. Background technique [0002] Oxygen inhalation is the most common clinical treatment method, and effective humidification is required when dry medical oxygen is used. The existing oxygen humidification device is generally composed of a disposable bottle-shaped hard container pre-filled with humidification liquid, which is difficult to withstand traditional heat sterilization and has high cost; the humidification method is air bubble type water humidification or surface humidification , when there are pathogenic bacteria in the humidification liquid, there is a huge risk in the air-bubble humidification method, while the surface humidification method will not bring pathogenic bacteria into the oxygen flow; and regardless of the humidification method, the humidification liquid usually For indoor use,...

Problems solved by technology

The existing oxygen humidification device is generally composed of a disposable bottle-shaped hard container pre-filled with humidification liquid, which is difficult to withstand traditional heat sterilization and has high cost; the humidification method is air bubble type water humidification or surface humidification , when there are pathogenic bacteria in the humidification liquid, there is a huge risk in the air-bubble humidification method, while the surface humidification method will not bring pathogenic bacteria into the oxygen flow; and regardless of the humidification method, the humidification liquid usually For indoor use, oxygen humidification at room temperature, when the oxygen flow rate is higher than 5L / Min, the humidification effect will drop significantly, and it is difficult to reach above 60% RH, and the heating and humidifying ability of the respiratory tract itself of oxygen inhalers, especially critically ill patients Decreased due to disease, dry oxygen will not only damage the airway, but also make sputum dry and scab hard to cough up, and sputum scab blocking the airway will be life-threatening. Providing warm and moist oxygen flow according to individual needs is the development of clinical medicine. need
