Compared with the above embodiments, the endoscopic-dedicated oropharyngeal channel disclosed in the present embodiment is different in that: the endoscope-specific oropharyngeal passage includes a mouthpiece 10, and an air intake chamber 4 for supplying oxygen to the patient's mouth and an oxygen port 6 communicating with the air intake chamber 4 are provided on the mouthpiece 10.
In fact, the complete sequence of operation of a clinical painless endoscope is typically: the patient lies on the side, wears a mouthpiece well, inhales oxygen at a large flow rate, injects anesthetic into veins, inserts a tongue pressing bending plate into an oropharynx channel after the patient loses consciousness, and starts endoscope operation;
if the air inlet cavity 4 and the air exhaust cavity 5 are both arranged on the tongue depressing bending plate 1, the following problems can occur: before anesthesia, a patient needs to firstly carry out large-flow oxygen inhalation, and the tongue-spatula 1 is not inserted into the oropharyngeal passage of the patient at the moment, so that the patient can only carry out various operations through an additionally arranged oxygen supply device (such as an oxygen tube or an oxygen supply mask), and after the anesthesia is finished and the tongue-spatula 1 is inserted into the oropharyngeal passage of the patient, an oxygen source needs to be switched to an oxygen interface of the tongue-spatula 1, so that the operation is relatively complicated on one hand, and is not scientific and reasonable on the other hand;
in the special oropharyngeal passage for the endoscope disclosed in the embodiment, the air inlet cavity for supplying oxygen to the patient is arranged on the mouthpiece 10, the mouthpiece 10 is worn before the patient is anesthetized, and the mouthpiece 10 is not removed after the patient is anesthetized, so that the oxygen source does not need to be transferred in the whole endoscope operation process.
Furthermore, an oxygen supply nasal catheter for supplying oxygen to the nasal cavity of a patient is further arranged on the mouthpiece, in the special oropharyngeal channel for the endoscope, the tongue pressing bending plate 1 is provided with the exhaust cavity 5, in the painless endoscopy process, the tongue pressing bending plate 1 can be embedded into the oral cavity and the throat of the patient, so that the end inlet 51 of the exhaust cavity 5 can collect gas exhaled by the patient and convey the gas to the carbon dioxide monitoring interface 7, the end-expiratory carbon dioxide index of the patient can be monitored, and the oxygen outlet of the air inlet cavity arranged on the mouthpiece 10 can supply oxygen to the near end in the oral cavity of the patient, so that the special oropharyngeal channel for the endoscope also has the advantage of improving the accuracy of exhaled gas collection; meanwhile, the panel 2 is provided with an opening 3 for the endoscope to pass through, so that the operating space of the endoscope is reserved after the tongue depressing bending plate 1 is embedded in the oral cavity of a patient.
Therefore, the oropharyngeal passage special for the endoscope disclosed by the embodiment of the invention can supply oxygen at a large flow rate in the painless endoscopy process and simultaneously monitor the end-tidal carbon dioxide index of a patient, so that the incidence rate of hypoxemia of the patient in the painless endoscopy process is effectively reduced.
Similarly, a carbon dioxide parameter sensor is integrated at the end inlet 51 of the oropharyngeal passage special for the endoscope, and the carbon dioxide parameter sensor can be in communication connection with the end-tidal carbon dioxide monitor in a wired or wireless mode, so that the accuracy of collection of expired gas of a patient is further improved.
