Oropharyngeal airway

Abstract

The invention discloses an oropharyngeal airway. The oropharyngeal airway includes a flange, a connecting plate mechanism is embeddedly installed into the top of the flange, the bottom of the flange is connected with a connecting rope, a dental pad is installed on one side of the flange, an airway main body is installed on the other side of the dental pad, and one side, close to the airway main body, of the dental pad is provided with a positioning mechanism. After the airway main body is inserted into a patient, the connecting rope can be wound from the outside of a patient head, hooks are combined with positioning buckles to complete fixing of the device, so that the device is prevented from falling off from a patient mouth, at the same time a way of connecting a lanyard from ears is abandoned, and discomfort to the patient ears is avoided; and fixing of the outer side of the airway main body can be completed by using a way of clamping from the outer side, so that the problem that the other end damages a patient throat or the patient throat is stimulated and vomited due to change in angle is avoided, and the easy-to-use effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an oropharyngeal ventilation tube. Background technique [0002] The oropharyngeal airway is a non-tracheal catheter non-invasive ventilation tube, which can prevent the tongue from falling back, quickly open the airway, obtain effective ventilation, and maintain the upper airway. The floor of the mouth and the pharynx are relaxed, and the tongue and epiglottis can fall backward into the posterior pharyngeal wall, causing upper airway obstruction. When the oropharyngeal airway is inserted correctly, its front end can lift the tongue and epiglottis from the posterior pharyngeal wall, In order to achieve the purpose of preventing or treating upper airway obstruction, the existing oropharyngeal ventilation tube is easy to fall off after the patient is inserted into the oropharyngeal ventilation tube during use, while some oropharyngeal ventilation tubes adopt a s...
