Abstract

The embodiment of the invention discloses a nasopharynx ventilating pipeline. The nasopharynx ventilating pipeline comprises an inflating bag, a dosing bag and a main pipe. The main pipe is formed according to the natural radian of a nasopharynx air way and is in an arc shape, and is provided with a near end for penetrating into the pharynx oralis and a far end located outside the nasal vestibule.A ventilating cavity stretching from the far end to the near end is formed in the main pipe, and thus a near end ventilating opening and a far end ventilating opening are formed respectively. The inflating bag is arranged at the near end and provided with a columnar space, an inner cavity of the inflating bag is communicated with a far end inflating valve of an inflating pipe cavity, the near endventilating opening tilts up towards the abdomen side of a pipe body by being opposite to the axis of the near end of the ventilating cavity, and therefore a near end ventilating opening guide end tilting-up part is formed. The nasopharynx ventilating pipeline has the advantages of being simple in structure, convenient to manufacture and low in cost, and is easy to use and popularize.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of medical devices, in particular to a nasopharyngeal airway. Background technique [0002] In clinical medicine, the nasopharyngeal airway is an important tool widely used in assisted ventilation for patients during general anesthesia and first aid for critical cases. The success of establishing an artificial airway quickly and effectively directly affects General anesthesia and rescue success rate. The current traditional operation method is to place the nasopharyngeal airway along the patient's proper oral cavity at the confluence of the oropharynx and hypopharynx, and the patient's end of the airway directly reaches the glottis. However, due to the complexity of human anatomy and individual differences in tolerance, there are still reasons for nasal mucosal damage or ventilation failure. Moreover, the traditional nasopharyngeal airway cannot perform surface anesthesia on the n...
