Abstract

The invention discloses a heat moisture exchanger which comprises a tubular shell, wherein two ends of the tubular shell are respectively provided with a filter element; the tubular shell is provided with an oxygen inlet, a general-purpose connector and a sputum suction connector; the tubular shell is also provided with a humidification connector and is internally provided with a first diversion component used for diverting a humidizer flowing in from the humidification connector to the filter element; the humidizer flows into a sputum suction pipe through the humidification connector, and then is mixed with oxygen so as to enter into the body of a patient. By virtue of implementing the heat moisture exchanger provided by the embodiment of the invention, the humidizer is fully mixed with the oxygen, so that a better humidification and warming effect is achieved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a heat and moisture exchanger. Background technique [0002] Heat and moisture exchanger (HME) is a commonly used clinical medical device, mainly used in the medical care process of anesthesia patients, ICU intensive care unit patients, etc. Although the ventilator and breathing circuit provide the possibility of artificial ventilation for patients with breathing difficulties, the gas output by the ventilator does not have the humidity or temperature suitable for the human lung environment during use. At present, patients who are intubated under artificial ventilation usually heat and humidify the gas in two ways. The first way: when the patient is expected to be intubated for less than 72 hours, a heat and moisture exchange device is added to the artificial ventilation device. The HME operates by retaining heat and humidity from the patient's exhaled air and giving most of t...
