Description

Technical Field

[0001] The utility model relates to the field of oxygen humidifying devices, in particular to an oxygen humidifying device which is convenient for preventing backflow. Background Art

[0002] Oxygen humidification is a rehabilitation device and ward nursing consumables, mainly used in the oxygen supply system of the medical center, which can supply oxygen to medical units for emergency treatment and oxygen inhalation for hypoxic patients. In the prior art, the Chinese utility model patent with the publication number of CN213911895U and the patent name of "A conveniently adjustable anti-backflow respiratory oxygen humidification device" discloses an oxygen humidification device. The patent records the setting of the first one-way valve and the second one-way valve on the oxygen pipe and the exhaust pipe, which can effectively prevent backflow and avoid oxygen contamination. The setting of the flow regulating mechanism composed of the fixed sleeve and the fixed bolts on the top of the humidification tank squeezes the exhaust pipe by tightening the fixed bolts. The flow rate can be adjusted more conveniently. Two sets of partitions are arranged inside the base. The partitions can separate the water inside the humidifier tank, so that in the process of water injection through the liquid inlet, the leakage of oxygen can be effectively avoided, and the use is more convenient. In this scheme, during the water injection process, the external gas is connected with the humidifier tank. Although the partition separates the water, the liquid water is connected with each other. Oxygen can still flow to the side position and flow out from the liquid inlet. External gas can also easily enter through the liquid inlet, mixing the gas. The humidity of the humidified gas is not easy to adjust. The excessive moisture of the oxygen also brings discomfort to the user who breathes. In order to solve this problem, an oxygen humidification device that is convenient for preventing backflow is proposed. Utility Model Content
