Abstract
The utility model relates to the field of medical instruments, and mainly aims to provide an endoscopic oropharyngeal airway in order to solve the clinical problems of airway obstruction and the like in peroral digestive endoscopy or operation. The endoscopic oropharyngeal airway comprises an anti-bite oral ring (1), an oropharyngeal airway body and a ventilation sputum suction channel (4), wherein the oropharyngeal airway body comprises an air duct oral ring portion (2), an air duct body (3) and an air duct outer opening (5). By the aid of the endoscopic oropharyngeal airway, safety of the digestive endoscopy or operation in intravenous general anesthesia is guaranteed.
Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of scope type oropharyngeal airway.
Background technology
The patient accepts per os digestive endoscopy inspections such as gastroscope under non-intubation and general anaesthesia and there is certain risk in treatment.This is because short time digestive endoscopy needed depth of anesthesia of when operation is not dark, only with intravenous anesthesia but not tracheal intubation can finish.But do not having under the intravenous anesthesia state of tracheal intubation, the patient causes airway obstruction most probably because of glossoptosis, thereby mortality thunder boltes such as respiratory failure, cardiopulmonary arrest take place.
The control glossoptosis mainly relies on oropharyngeal airway or nasopharynx airway at present.But existing oropharyngeal airway when carrying out endoscopic technic can't pass through digestive endoscopy because bore is meticulous.
Still there is not at present the oropharyngeal airway that is applicable to endoscopic technic.
The utility model content
Main purpose of the present utility model is to provide a kind of scope type oropharyngeal airway, and clinical problems such as airway obstruction can take place during with solution per os digestive endoscopy inspection or operation.
This utility model for achieving the above object, the main technical schemes that provides is:
A kind of scope type oropharyngeal airway comprises anti-type mouth circle, oropharyngeal airway and the ventilation suction expectorant passage stung; Oropharyngeal airway is made up of ventilation road junction circle portion, airway main body and airway collar extension; The airway main body is arcuate structure, and an end is connected with the ventilation road junction circle portion of vertical centering control hollow structure, penetrates the anti-type mouth circle of stinging in the circle portion of ventilation road junction, and the airway collar extension is positioned in the circle portion of ventilation road junction; The side that the expectorant passage is positioned at the airway main body is inhaled in ventilation, is opened on the airway collar extension.
Oropharyngeal airway is semi-open type structure, and the anti-type mouth circle of stinging places in the circle portion of ventilation road junction, through preventing that stinging type mouth circle inserts the oral cavity, digestive endoscopy passes through from anti-stinging in the type mouth circle, the airway main body is arcuate structure, tongue body can be fixed in the below of arc, thereby avoid glossoptosis.
The expectorant passage is inhaled in ventilation, can insert for Oxygen uptaking catheter or sputum aspirator tube, for oxygen uptake or suction expectorant.
The tip of airway main body is positioned at patient epiglottis the place ahead or epiglottic vallecula, is conducive to the location of scope and directly supports or inhale expectorant to glottis portion.
Described airway collar extension is the outer extended structure of ventilation road junction circle, thereby can avoids the complete inlet port circle of oropharyngeal airway to slide in the oral cavity.
This utility model can be different with the different making of stature according to scope specification and patient age specifications and models, to cater to clinical demand.
Advantage of the present utility model is: under implementing general intravenous anesthesia when digestive endoscopy inspection or operation, tongue body is fixed in the airway below, simultaneously can inhale the expectorant passage through ventilation and carry out oxygen uptake or inhale expectorant, ensure the safety of digestive endoscopy inspection under the general intravenous anesthesia or operation.
Description of drawings
Fig. 1 is this utility model structural representation;
Wherein: the 1 anti-type mouth circle of stinging; 2 ventilation road junction circle portions; 3 airway main bodys; The expectorant passage is inhaled in 4 ventilations; 5 airway collar extensions; 6 scopes.
The specific embodiment
Now in conjunction with the embodiments and accompanying drawing, this utility model is further described, but enforcement of the present utility model is not limited in this.
Embodiment 1:
As shown in Figure 1, a kind of scope type oropharyngeal airway comprises anti-type mouth circle 1, oropharyngeal airway and the ventilation suction expectorant passage 4 stung; Oropharyngeal airway is made up of ventilation road junction circle portion 2, airway main body 3 and airway collar extension 5; Airway main body 3 is arcuate structure, and an end is connected with the ventilation road junction circle portion 2 of vertical centering control hollow structure, penetrates the anti-type mouth circle 1 of stinging in the ventilation road junction circle portion 2, and airway collar extension 5 is positioned in the ventilation road junction circle portion 2; The side that expectorant passage 4 is positioned at airway main body 3 is inhaled in ventilation, is opened on airway collar extension 5.
Embodiment 2:
During use, the patient bites the anti-type mouth circle 1 of stinging before accepting general anesthesia, and airway main body 3 is inserted from anti-stinging in the type mouth circle 1, slips into retropharynx along the tongue body top, props up a mouthful circle 1 until ventilation road junction circle portion 2 inlet port circles 1 and airway collar extension 5.Anestheticing period is inserted ventilation with Oxygen uptaking catheter and is inhaled expectorant passage 4, if secretions can be inserted sputum aspirator tube passage 4 for a long time, thereby oxygen uptake is provided and inhales expectorant.During endoscopic technic, scope 6 can pass from ventilation road junction circle portion 2, slips into pharyngeal cavity and enters esophagus along airway main body 3.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; that describes in above-described embodiment and the description just illustrates principle of the present utility model; this utility model also has various changes and modifications under the prerequisite that does not break away from this utility model spirit and scope, and these changes and improvements all fall in claimed this utility model scope.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
