Anti-backflow oxygen humidifying device for pneumology departments

Abstract

The invention discloses an anti-backflow oxygen humidifying device for pneumology departments, and particularly relates to the field of oxygen humidification for pneumology departments. The device comprises a box body; a water treatment chamber and a gas treatment chamber are respectively and fixedly arranged on two sides of the inside of the box body; a mixing chamber, a storage chamber and an adjusting mechanism are arranged between the water treatment chamber and the gas treatment chamber; the storage chamber is positioned at the top of the mixing chamber; the adjusting mechanism is positioned between the mixing chamber and the storage chamber; a drainage mechanism and an exhaust mechanism are respectively and fixedly arranged on two sides of the inside of the mixing chamber, wherein the drainage mechanism and the exhaust mechanism are arranged correspondingly; a water storage box is fixedly arranged on the top of the inside of the water treatment chamber; and a first water storagemetering box, a second water storage metering box, a third water storage metering box and a first mounting box are fixedly arranged at the bottom end of the inside of the water treatment chamber. According to the invention, through arrangement of the water treatment chamber and the gas treatment chamber, new oxygen supply and water supply sources can be provided in each treatment stage, and oxygenand water are effectively prevented from being polluted due to backflow.

Description

technical field [0001] The invention relates to the field of oxygen humidification in respiratory department, more specifically, the invention relates to an oxygen humidifier for respiratory department with anti-backflow. Background technique [0002] Oxygen itself is a dry and pure gas without humidity. The human body will be very dry after inhalation, so the inhaled oxygen needs to be moistened with water. Oxygen is necessary for patients in clinical practice, but if the oxygen is not pre-wetted, it will cause the patient to inhale. It's uncomfortable. [0003] However, most of the existing anti-backflow oxygen humidification devices for respiratory department use a single water supply and oxygen supply source, which cannot provide new oxygen supply and water supply sources in multiple treatment stages, and are prone to contamination of oxygen and water sources due to backflow. Contents of the invention [0004] In order to overcome the above-mentioned defects of the pr...
