Embodiment Construction

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0030] Such as Figure 1-8 As shown, the present invention provides an oropharyngeal airway with airway surface anesthesia function. The oropharyngeal airway is an oval tubular structure, including a flange 1, a dental pad portion 2 and a pharyngeal bend 3 arranged in sequence, and the wing There is a dosing port on the edge 1, and a spraying port 31 is provided in the inner cavity at the end of the pharyngeal flexure 3. The internal dosing tubing connection. ...

Abstract

The invention provides an oropharynx breather pipe having an airway surface anesthesia function, relates to the technical field of medical anesthesia equipment, and solves the technical problems thatan oropharynx breather pipe in the prior art can only assist in ventilation and is single in functions. According to the oropharynx breather pipe having an airway surface anesthesia function, the oropharynx breather pipe is of an oval tubular structure and comprises a flange, a bite block part and a pharynx bending part which are sequentially arranged, a medicine adding opening is formed in the flange, and a medicine spraying opening is formed in an inner cavity in the tail end of the pharynx bending part; and the medicine adding opening and the medicine spraying opening are connected througha medicine feeding pipeline embedded in the flange, the bite block part and the pharyngeal bending part. The oropharynx breather pipe disclosed by the invention is used for improving the clinical useperformance of the oropharynx breather pipe.

Description

technical field [0001] The invention relates to the technical field of medical anesthesia equipment, in particular to an oropharyngeal ventilation tube with airway surface anesthesia function. Background technique [0002] Patients under general anesthesia generally need tracheal intubation. During tracheal intubation, laryngoscope is the first choice for tracheal intubation. Epiglottis, glottis and airway are stimulated during intubation, resulting in obvious blood flow Increased dynamics. [0003] At present, there are two ways to reduce the intubation reflex, one is to use propofol, opioids and muscle relaxants to increase the depth of anesthesia to suppress the intubation reflex; the second is to use anesthesia equipment to anesthetize the oropharynx and airway surface to reduce the intubation reflex. In the second method, items such as watering cans or laryngeal anesthesia tubes are generally used clinically for topical anesthesia, but there are some disadvantages in ...
