Disposable aseptic oxygen humidifier

Abstract

Oxygen inhalation is the most common therapeutic method in clinic, but the disinfection and sterilization of the existing device of oxygen inhalation--oxygen inhalator and water used for the oxygen inhalator are still a hard problem; in addition the humidification effect is not good, the noise is high, and the daily disinfection of the humidification bottle and the addition and displacement works of the water are complicated. The device of the invention--disposable aseptic oxygen humidifier comprises a disposable humidification bottle (6) filled with water for cleaning, a bottle mouth inner cap (3) provided with an oxygen inlet and outlet (4, 5), an oxygen guide pipe (7), a specially designed bubble controller (9) capable of adjusting the size of oxygen bubbles and reducing the noise, a special and sealed rubber plug (2) used for sealing and connecting a flowmeter (1), a seal outer cap and the like. Before used, the product of the invention is sterilized and sealed to be clean and aseptic; when the humidifier is used, the bottle cap is opened, the humidifier is connected with the flowmeter to ensure that the humidifier can be conveniently used; during humidification process, small oxygen bubbles can be generated by adjusting the bubble controller, the total contact area of numerous small oxygen bubbles (8) and water is far larger than that of bigger bubbles with the same total volume and water, the humidification effect is increased, and the noise generated by bubbles is obviously reduced.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable aseptic oxygen humidifier for medical oxygen inhalation. Background technique [0002] Oxygen inhalation is the most commonly used clinical treatment method, and the oxygen inhalation device commonly used in clinical practice --- the oxygen inhaler consists of two parts: a flow meter and a humidification bottle. In order to prevent cross-infection caused by oxygen inhalation, the humidification bottle must be disinfected regularly, and the sterilized humidification water also needs to be added and replaced frequently. However, the disadvantages of the existing oxygen inhalation equipment are: it is difficult to ensure that the humidification bottles for batch disinfection are not recontaminated during storage in the ward due to the opening of the bottle mouth; the aseptic operation cannot be realized during the process of adding and replacing the sterile humidificati...
