Description

Filtering device for oral cavity temperature and humidity

Technical Field

The utility model relates to the technical field of medical supplies, especially, relate to a filter equipment for oral cavity is warm and humid.

Background

During normal breathing, the air flow channels are nasal cavity, nasopharyngeal cavity and pharyngeal cavity, and the air exchange is carried out through the normal breathing channel, and the air can be filtered, heated and humidified. Some patients clinically have respiratory function inhibition, cough and swallowing reflex disorder due to the reasons of old age, obesity, tongue tenesmus, consciousness loss, critical illness and the like, and have tachypnea and mouth-opening respiration.

The open-mouth breathing refers to a breathing mode that the upper airway is completely or partially blocked, so that airflow completely or partially passes through the nasal cavity and directly enters the lower airway through the oral cavity. The nasal cavity loses normal ventilation function by mouth-opening respiration, and air and oxygen are mainly inhaled into the lungs of a patient through the oral cavity.

Mouth-opening breathing makes patient's oral mucosa expose and leads to in the air cold, dry even unclean air directly gets into the oral cavity and gets into the respiratory track, the air current takes away moisture when passing through, make the patient produce the xerostomia symptom easily, make oral mucosa lose normal humidifying, lubrication and cleaning action, cause the antibiotic substance in the oral cavity to generate and reduce, in addition coma, high fever, the use of dehydration medicine, fast for a long time, drink forbidding, make patient's oral mucosa saliva secretion volume reduce, organism resistance greatly reduced, oral cavity self-cleaning function weakens, it splits to cause oral cavity lips, mucosa damage is bled and makes oral mucosa shielding function weaken.

In addition, when the mouth is opened for breathing, gas directly enters the lower respiratory tract through the mouth without humidification and filtration, so that the oral cavity, the throat and the lower respiratory tract are dried, the epithelial cells of the trachea are damaged, respiratory mucosa erosion, bacterial infection, airway secretion increase, airway obstruction and even asphyxia are caused. Further exacerbation will lead to the establishment of artificial airways that threaten the patient's life safety, leading to prolonged hospital stays and increased hospital costs.

In the prior art, the mouth of a patient is covered with oily gauze or wet gauze aiming at a mouth-opening breathing patient clinically, but the gauze is not fixed by a corresponding object, so that hands cannot be liberated, and the gauze is easy to fall off along with involuntary movement of the head and the face of the patient. Meanwhile, at present, a humidifying device is also arranged for the oral gas, but the device is heavy, and the problem of carbon dioxide re-absorption and the like are easily caused in a closed environment.
