Natural heating artificial air flue humidification machine

Abstract

The invention provides a natural heating artificial airway humidifier, which can solve the problems of atelectasis, decrease of blood oxygen partial pressure and etc. due to the complicated operation and the long-term atomization in the prior art. The technical proposal of the invention is that, the natural heating artificial airway humidifier comprises a liquid storage bag, an artificial nose and a gas returning tube, the liquid storage bag and the artificial nose therein are connected by a liquid transport tube therebetween, which is characterized in that the artificial nose is provided with an outer shell, the inner cavity of the outer shell is an artificial nasal cavity, an artificial nasal concha is arranged in the artificial nasal cavity, the upper end of the artificial nasal concha is connected on the inner wall of the upper end of the artificial nasal cavity, the artificial nasal concha is shaped like a bag which is formed by a plurality of folds, the inner layer of the wall surface of the artificial nasal concha is a net membrane, the outside of the net membrane is provided with moisture absorption materials, while the liquid transport tube and the gas returning tube are communicated with the artificial nasal concha. As the humidifying liquid is immersed in the moisture absorption materials in the artificial nasal concha, the artificial nasal cavity is filled with warm and humid gas; the humidified exchange gas can protect the trachea and alveolar mucosa and avoid the dryness, scar and ulcer and lung infection.

Description

technical field [0001] The invention relates to a medical device, in particular to a humidifier for heating, humidifying and cleaning the inhaled gas of an artificial airway. Background technique [0002] For patients with laryngeal cancer and other patients who need to be inserted with an artificial airway, the establishment of an artificial airway through tracheal intubation and tracheotomy is an important measure to treat such critically ill patients. Under normal circumstances, the human nasal cavity, pharyngeal cavity, and mucous membrane of the respiratory tract have physiological functions of warming, humidifying, and cleaning the inhaled gas. However, after the artificial airway is established, the inhaled gas avoids the physiological function of natural warmth and moisture The nasal cavity and the upper respiratory tract must all have the trachea and the respiratory tract below to heat and humidify, resulting in an increase in the loss of water in the respiratory se...
