Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable heat and moisture exchange filter. Background Art

[0002] The moisture exchange filter is a respiratory filter device that can be used in medical devices such as masks, endotracheal tubes, laryngeal masks, etc. connected to ventilators and anesthetics. Under normal circumstances, the moisture exchange filter can achieve a filtration effect of 99.999%. Since the moisture exchange filter has a very high filtration effect, its application can reduce the risk of cross-infection between the human body and the external environment during breathing. In addition, the moisture exchange filter is also used to filter viruses and bacteria in the breathing circuit and maintain the temperature and humidity in the breathing circuit.

[0003] The existing heat and moisture exchange filter has a medium inside. In order to prevent the medium from being damaged before use, a cover is usually set on the upper end of the filter and then sealed. In the prior art, the filter used by adults and children has different specifications because of the different air flow rates. If a heat and moisture exchange filter that can adjust and switch airflow can be designed, the use range of the filter can be expanded. Utility Model Content
