Abstract
The utility model relates to a three-channel laryngeal mask in the field of medical apparatus and instruments. The three-channel laryngeal mask comprises a mask body, an air guide tube, an inflation tube and a drainage tube, wherein an air sac is connected to the periphery of the mask body and one end of the inflation tube; the other end of the inflation tube is connected with an inflation valve; the air guide tube is communicated with the inner side of a space which is encircled by the air sac; and the drainage tube extends from the back end of the air sac to the front end of the air sac. When the three-channel laryngeal mask works, the mask body is inserted into the throat of a patient from the oral cavity of the patient, air is filled into the air sac by the inflation tube so as to swell the air sac to cover the throat of the patient, and simultaneously, air required for breathing of the patient can be introduced through the air guide tube; food can be drained by the drainage tube if the patient suffers from food backflow during anesthesia; and an inserting tube can be inserted into the stomach of the patient by the drainage tube to directly supply nutrient food to the patient when the patient is in need of the food. The three-channel laryngeal mask is convenient for the patient to take food and be subjected to drainage, and can be widely applied to emergency treatment, anesthesia, treatment of respiratory failure and the like.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of throat intubate utensil.
Background technology
Laryngeal mask (LMA) is a kind of breather of special type, and at prolate shape cover made from silicone rubber of front end linking of its breather, its size can cover larynx just, so claim again laryngeal mask snorkel.At present, in oneself the breathing management when being widely used in general anesthesia of laryngeal mask.
In the Chinese patent database, a kind of laryngeal mask is arranged, its application number: 201020561934.X, the applying date: 2010-10-05, open day: 2011-04-27, its structure comprises cuff, gas tube, be arranged at the indication sacculus on the gas tube and be arranged at charge valve in the gas tube free end port, and gas tube is communicated with cuff, and cuff is communicated with an oropharyngeal airway.Its weak point is: during this device work, oropharyngeal airway links to each other with oxygen supply equipment, to patient's oxygen supply.When patient is in narcotism, sometimes have food reflux, laryngeal mask for blocking, such as untimely cleaning, the food that backflows may enter trachea.
The utility model content
The purpose of this utility model provides a kind of three channel throat cover, can in time clear up the food that backflows, and in oxygen supply, can also feed food or medicine in Stomach in Patients.
The purpose of this utility model is achieved in that a kind of three channel throat cover, comprise cover body, airway and gas tube, the cover body periphery is connected with air bag, described air bag links to each other with gas tube one end, the gas tube other end links to each other with charge valve, airway communicates with the inboard, space that air bag is enclosed, and also includes drainage tube, and drainage tube extends to the air bag front end from the air bag rear end.
During this utility model work, cover body is inserted into throat from the oral cavity, is filled with air by gas tube again, and airbag inflation is heaved, cover larynx, at this moment, can import the human body respiration desired gas by airway, the patient if any food reflux, can draw by drainage tube in anaesthesia process; When needs supply food to the patient, also can intubate be inserted by drainage tube and directly supply with nutriment in the Stomach in Patients; The cover body of this device is made by medical grade silicon rubber.Compare with endotracheal intubation, the laryngeal mask zest is little, and respiratory tract mechanical obstruction is few, and patient is easy to accept.Cardiovascular system reacts less when inserting as and extracting, and postoperative is less has sore throat.Owing to adopted drainage tube, made things convenient for patient's feed and drain, can be widely used in the treatment of first aid, anesthesia, respiratory failure etc.
Degree of inflation for the energy pilot balloon is provided with pilot balloon between described gas tube and the charge valve.The fullness degree of pilot balloon can judge whether air bag is in full state for the doctor.
For ease of fixing, described gas tube, airway and drainage tube link together through backing plate.When backing plate can be avoided dental articulation gas tube, airway or drainage tube are stung badly, improved the dependability of device.
Description of drawings
Fig. 1 is this utility model structural representation.
Wherein, 1 air bag, the space that 2 air bags are enclosed, 3 charge valves, 4 pilot balloons, 5 gas tubes, 6 airways, 7 drainage tubes, 8 backing plates.
The specific embodiment
As shown in the figure, be a kind of three channel throat cover, comprise cover body, airway 6, drainage tube 7 and gas tube 5, the cover body periphery is connected with air bag 1, air bag 1 links to each other with gas tube 5 one ends, and gas tube 5 other ends link to each other with charge valve 3, also is provided with pilot balloon 4 between gas tube 5 and the charge valve 3, airway 6 communicates with the inboard in the space 2 that air bag is enclosed, and drainage tube 7 extends to air bag 1 front end from air bag 1 rear end.。Gas tube 5, airway 6 and drainage tube 7 link together through backing plate 8.
This utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of this utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
