Description

Oropharynx breather pipe convenient to monitor end-expiratory carbon dioxide concentration

Technical Field

The utility model relates to the technical field of oropharyngeal ventilation tubes, in particular to an oropharyngeal ventilation tube convenient for monitoring the concentration of end-expiratory carbon dioxide.

Background

The oropharynx air duct is also called as an oropharynx air duct, is a non-tracheal catheter non-invasive air duct, can prevent tongue from falling backward, quickly opens the air duct and establishes a temporary artificial air duct. The oropharyngeal airway is usually made of rubber or plastic, can also be made of metal or other elastic materials, is an elliptic hollow plastic tube which is commonly used in clinic, has an S-shaped appearance and comprises a flange, a bite block part and a pharyngeal bend part.

Wherein, the flange: the outer end of the mouth has a ring of protruding edges (i.e., flanges) to prevent swallowing and insertion too deeply. A bite block portion: the width of the occlusal portion of the pad portion contacting the teeth is sufficient to contact two or three teeth so that the occlusal pressure is evenly distributed to the contacting teeth. Pharyngeal bend: the curvature of the inner end of the pharynx bending part is suitable for the anatomy of the mouth, tongue and pharynx back.

Oropharyngeal airway is mainly used to maintain the patency of the upper respiratory tract: for anesthetized or comatose patients, the tongue and epiglottis may fall back into the posterior pharyngeal wall, causing obstruction of the upper airway, due to the relaxation of the muscles of the floor of the mouth and pharynx that support the tongue to maintain the patency of the upper airway. When correctly inserted into the oropharyngeal airway, the front end of the device can lift the tongue and the epiglottis from the posterior pharyngeal wall, thereby achieving the purpose of preventing or treating the upper respiratory obstruction. Compared to other methods of maintaining patency of the upper airway (e.g., chin lifting, chin support, and tracheal intubation), insertion into the oropharyngeal airway does not affect the stability of the patient's cervical spine.

The oropharyngeal airway tube used in the medical science at present has a simple structure, basically has no gas sampling monitoring component, cannot easily monitor whether a patient breathes spontaneously or not, and cannot clearly determine the end-expiratory partial pressure of carbon dioxide so as to analyze the respiratory gas components.
