Disposable multi-cavity laryngoscopic lens

Abstract

The invention relates to a disposable multi-cavity laryngoscopic lens which comprises a lens main body, wherein the lens main body is of an arc shape, and a tongue depressor is arranged at the front end of the inner arc surface; a laryngoscope mounting cavity opening at the back end and a ventilation pipeline and a secretion discharge pipeline connecting the front and back ends are arranged in the lens main body; the ventilation pipeline and the secretion discharge pipeline are arranged in parallel below the laryngoscope mounting cavity and laid out in a shape of Chinese character 'Pin' and are parallel to each other; and an oxygen supply joint and a liquid suction joint are arranged at the back ends of the ventilation pipeline and the secretion discharge pipeline respectively. So, after the laryngeal is forced open and the disposable multi-cavity laryngoscopic lens is inserted, oxygen can be input into the airway of the patient through the ventilation pipeline while liquid in the mouth cavity is removed by suction through the secretion discharge pipeline. With powerful functions, the disposable multi-cavity laryngoscopic lens avoids repeated pulling / inserting of an oxygen pipe and a liquid suction pipe in a traditional structure and has the advantages of convenience, flexibility and quickness in operation, high rescue efficiency, good effect, simple structure, easiness in production and processing, low processing cost and remarkably strong market competitiveness and facilitates market promotion, popularization and application.

Description

technical field [0001] The invention belongs to the technical field of laryngoscope equipment, in particular to a disposable multi-cavity laryngoscope blade. Background technique [0002] At present, (electronic) laryngoscopes on the market will be equipped with a disposable laryngoscope lens when used. These existing laryngoscope lenses all include a lens body, the front end of the inner arc surface of the lens body is provided with a tongue depressor, and the tongue depressor and the lens body are integrally formed by transparent materials. When in use, it is inserted into the patient's throat, the throat is pried open, and then the oxygen supply tube is inserted into the airway of the throat and the suction tube is inserted into the throat; however, the throat is closed when the patient is in a coma, and the The opening space of the laryngoscope is extremely limited, and it is necessary to repeatedly insert and pull out the oxygen supply tube and suction tube, and it is ...

Problems solved by technology

When in use, it is inserted into the patient's throat, the throat is pried open, and then the oxygen supply tube is inserted into the airway of the throat and the suction tube is inserted into the throat; however, the throat is closed when the patient is in a coma, and the The opening space of the laryngoscope is extremely limited, and it is necessary to repeatedly insert and pull out the oxygen supply tube and suction tube, and it is difficult to quickly and accurately find the airway in the larynx and insert the oxygen supply tube, which seriously affects the insertion efficiency and the insertion operation is also difficult. Extremely inconvenient, it is prone to cerebral hypoxia, which may cause sequelae such as brain injury and liquid into the airway, delaying rescue time, reducing the success rate of rescue, and it is easy to injure the throat
