Problems solved by technology
[0003] After the filter material in the temperature-humidity exchanger has been used for a period of time, the air flow through the filter material will become smaller due to tracheal secretions blocking the filter material, which will lead to insufficient inspiratory volume of the patient. If the temperature-humidity exchange device cannot be replaced in time device, which may present a choking hazard to the patient
[0004] However, since medical staff are usually very busy, sometimes there is not enough time to replace the temperature and humidity exchanger, so how to provide a buffer time for replacing the temperature and humidity exchanger, so as to ensure the safety of patients and facilitate the medical staff to arrange the replacement time of the temperature and humidity exchanger , still a problem to be solved

A heat and moisture exchanger comprises a shell body and a filtering wet storage unit. The shell body is provided with an encircling wall, a respiratory air connector, an oxygen connector and an adjustable air hole unit. A containing space is defined in the encircling wall, the respiratory air connector is placed on the encircling wall, a first channel communicating with the containing space and the environment outside the shell body is defined in the respiratory air connector, the oxygen connector is arranged on the encircling wall, and a second channel communicating with the containing space and the environment outside the shell body is defined in the encircling wall. The adjustable air hole unit is placed in the encircling wall and comprises an air hole around the wall, and the air hole is used for communicating the containing space and the environment outside the shell body and can be controlled to open or close. The filtering wet storage unit is contained in the containing space and does not separate the air hole and the first channel. Insufficient air quantity can be supplied by opening of the air hole.
Description
technical field [0001] The invention relates to a medical product, in particular to a temperature-humidity exchanger connected with a tracheotomy tube. Background technique [0002] Generally, patients with a tracheostomy tube need to use a temperature and humidity exchanger to filter impurities in the gas and store moisture and heat through the exhaled gas of the patient itself, so as to humidify and warm the inhaled gas and avoid the inhaled gas from causing harm to the human body. discomfort. [0003] After the filter material in the temperature-humidity exchanger has been used for a period of time, the air flow through the filter material will become smaller due to tracheal secretions blocking the filter material, which will lead to insufficient inspiratory volume of the patient. If the temperature-humidity exchange device cannot be replaced in time device, which may present a suffocation hazard to the patient. [0004] However, since medical staff are usually very bus...
