Abstract

The invention discloses an artificial nose for solving the defect of complicated structure of a traditional artificial nose. The artificial nose comprises an upper shell, a middle shell and a lower shell which are sequentially communicated, wherein the outer end of the lower shell is provided and communicated with an air inlet, the outer end of the upper shell is provided and communicated with an air outlet which is communicated with the air inlet through a respiratory pathway, the air inlet and the air outlet are respectively communicated through a respiratory loop of a patient, the outer surface of the upper shell is also provided with a water inlet, the middle shell is also internally provided with a heating sheet and a water absorbing film which sequentially abut on the inner end of the water inlet from inside to outside, and filter films are respectively arrange at the inner end of the air inlet and the respiratory pathway of the lower shell. The artificial nose of the invention is internally provided with a heating and moistening device. When air enters the artificial nose through a respirator, the fed-in air is heated and moistened by the heating and moistening device of the artificial nose. During expiration, heat and water are brought in the respiratory pathway again.

Description

technical field [0001] The invention relates to a device, in particular to a medical breathing filter, namely an artificial nose, which can achieve a constant temperature and moisturizing effect. Background technique [0002] Artificial nose is also called biological filter, heat-moisture exchange filter, breathing filter, etc. It is a filter used by patients in the breathing circuit. It has different degrees of biological filtering function and heating and moisturizing effect, and is widely used in medicine. [0003] Existing artificial noses have the following deficiencies in design: (1) The most commonly used clinically is the passive heating and humidifying type, which is composed of a heater and a humidifier, which easily causes the patient to inhale cold and dry gas, making the mucus on the surface of the respiratory mucosa And the serous fluid thickens or dries up, the ciliary movement is hindered, and the secretion is difficult to discharge. In addition, if the threa...
