Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to an oxygen humidification bottle. Background Technology

[0002] Oxygen therapy is a commonly used nursing technique and emergency treatment in clinical practice. Currently used medical oxygen has a relative humidity of only about 3% when connected to the patient's oxygen delivery tube. Therefore, it must be humidified before entering the body to avoid irritating the patient's respiratory mucosa with dry oxygen. Conventional humidification bottles use a bubble-type structure. The principle of a bubble-type humidification bottle is as follows: high-speed airflow impacts water to create bubbles. These bubbles burst under gas pressure within the bottle, producing water vapor, which mixes with oxygen to form a humidified gas mixture that is then delivered to the patient.

The bottle body 1 contains water, and a bottle cap 3 is provided at the bottle opening to prevent the water inside the bottle body 1 from spilling out. The filter element 2 includes a first air inlet pipe 21 and a second air inlet pipe 22. The first air inlet pipe 21 is connected to the second air inlet pipe 22. A splash guard 23 is provided at the upper end of the first air inlet pipe 21 to prevent excessive water from splashing out of the bottle body 1. The splash guard 23 is snapped into the inside of the bottle opening of the bottle body 1. The lower end of the second air inlet pipe 22 extends to the bottom of the bottle body 1, and a filter cotton 4 is provided at the bottom end of the second air inlet pipe 22. Oxygen is humidified when it passes through the filter cotton 4. The bottle cap 3 is threadedly connected to the bottle body 1. The bottle body 1 is designed to be transparent, allowing easy observation of the working status of the filter element 2 through the bottle body 1. When in use, remove the bottle cap 3, insert the filter element 2 bottle knob into the flow meter 5 and connect it to the flow meter 5. Oxygen enters the first air inlet pipe 21 and the second air inlet pipe 22 of the filter element 2. The oxygen is humidified when it passes through the filter cotton 4 from the bottom end of the second air inlet pipe 22.

[0017] like Figure 3-4 As shown, the first intake pipe 21 and the second intake pipe 22 are configured as pipes with openings at both the top and bottom, and are integrally formed, communicating with each other.
