The conventional tracheal cannula and the like are often used for establishing an artificial airway to help a patient to assist in breathing, are often connected with medical equipment such as an oxygen supply device and the like, and establish a breathing management system to keep the patient breathing smoothly. However, in clinical work, there are also many cases where non-tracheal intubation general anesthesia, such as painless gastroenteroscopy, Endoscopic Retrograde Cholangiopancreatography (ERCP), painless abortion, painless ovariectomy, etc., is almost used. At this point, the anesthetic drug may cause a degree of respiratory depression in the patient; or to relaxation of the muscles of the laryngeal portion of the pharynx, causing obstruction of the upper respiratory tract, resulting in an increased incidence of hypoxic events in the patient. And the nasopharyngeal airway can be utilized to greatly solve the obstruction of the upper respiratory tract and keep the smooth of the expiratory tract.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, a particular embodiment of the present invention discloses a nasopharyngeal airway device 100 for assisting a patient in establishing assisted breathing, comprising a main conduit 10 and an oxygen donor conduit 20 and a monitoring subduct 30. The main conduit 10 comprises a proximal port 11 and a distal port 12; by proximal port is meant the port in the main conduit 10 that is proximal to the nasopharynx 40 of the patient; by distal port is meant another port in the main conduit 10 distal to the patient's nasopharynx 40. The proximal port 11 of the main conduit 10 may be extended into the patient's nasopharynx 40; the distal port 12 of the main conduit 10 is directly communicated with the atmosphere, so that the patient can freely breathe oxygen in the atmosphere through the main conduit 10, and free breathing is realized. The main conduit 10 is provided with a plurality of air outlet holes 13 at the end portion near the proximal port 11. Thus, oxygen can enter the nasopharynx part 40 of the patient through the plurality of air outlet holes 13, and the oxygen supply efficiency is further improved, so as to meet the requirements of the patient; and simultaneously, the patient can breathe the external air more smoothly through the main pipeline 10.

The oxygen supply and

monitoring subducts

20, 30 respectively enter the main duct 10 through the distal port 12 and extend towards the proximal port 11. The oxygen supply sub-line 20 is connected to an external oxygen supply device 50, and the monitor sub-line 30 is connected to an external monitor device 60. The oxygen supply device 50 supplies oxygen to the patient through the oxygen supply sub-conduit 20, and the monitoring device 60 monitors the amount of carbon dioxide exhaled by the patient by collecting the carbon dioxide through the monitoring sub-conduit 30, thereby achieving the purpose of monitoring the breathing condition of the patient in real time. Meanwhile, the patient can breathe the oxygen of the external atmosphere through the main pipeline 10, and free breathing is achieved.

As shown in fig. 2, the oxygen supply sub-pipe 20 and the monitoring sub-pipe 30 extend along the inner wall surface of the main pipe 10, and the first groove 14 and the second groove 15 are provided on the inner wall surface of the main pipe 10. The oxygen supply pipe 20 is embedded in and extends to the first groove 14; the monitor subduct 30 is embedded in and extends into the second recess 15. In particular, the outer wall surface of the oxygen supply pipe 20 is flush with the inner wall surface of the main pipe 10; the outer wall surface of the monitoring sub-pipe 30 is also flush with the inner wall surface of the main pipe 10. So on oxygen supply daughter pipe 20 and monitoring daughter pipe 30 are fixed in the internal face of trunk line 10 through embedding first recess 14 and second recess 15 respectively, avoid oxygen supply daughter pipe 20 and monitoring daughter pipe 30 crisscross in trunk line 10 together and hinder the circulation of air in trunk line 10 to oxygen supply daughter pipe 20 and monitoring daughter pipe 30 also can not occupy the inside circulation space of trunk line 10.

The oxygen supply pipe 20 extends to the near end port 11 of the main pipe 10; the monitoring subduct 30 extends to a predetermined length from said proximal port 11, in particular the monitoring subduct 30 may extend to a predetermined length from said proximal port 11 which may be one fifth of the total length of the main duct 10 or approximately one fifth of the total length of said main duct 10. Thus, the oxygen supply pipe 20 can supply oxygen to the deep part of the patient; the suction inlet of the monitoring sub-pipeline 30 is not too close to the discharge outlet of the oxygen supply sub-pipeline 20, so that the phenomenon that oxygen is insufficiently supplied due to the fact that oxygen discharged from the oxygen supply sub-pipeline 20 is sucked away by the monitoring sub-pipeline 30 can be avoided; meanwhile, the accuracy of monitoring the concentration of the carbon dioxide through the monitoring sub-pipeline is improved.

The above list of details is only a concrete description of possible embodiments of the invention, and they are not intended to limit the scope of the invention. Therefore, the equivalent embodiments or modifications without departing from the spirit of the present invention should be included in the protection scope of the present invention.
