Abstract
The utility model discloses a laryngeal-mask tracheal duct, which relates to a tracheal duct. The laryngeal-mask tracheal duct comprises a main air duct (1), a laryngeal-mask sleeve bag (2), a bullet-shaped head (3), and a thin duct (4); and the location where the main air duct moves is provided with two larger side ports (5), and the laryngeal-mask sleeve bag (2) a V-shaped high-volume and low-pressure inflatable sleeve bag whose most part winds the front end of the main air duct, which plays a role in sealing the periphery of the laryngeal in a smaller range and pressing the esophagus inlet by the bottom; the bullet-shaped head (3) is arranged at the joint of the main air duct (1) and the small thin duct (4) at the most front end, and the bullet-shaped head (3) is provided with a plurality of small holes (6) for ventilating; the thin duct (4) is arranged at the front end of the bullet-shaped head (3), which facilitates inserting into the lower trachea of the glottis without damaging the mucous membrane and has small irritation for the trachea.
Description
Technical field:
This utility model relates to a kind of endotracheal tube, especially relates to a kind of laryngeal mask type endotracheal tube.
Background technology:
The anesthesia field mainly contains laryngeal mask and endotracheal tube two big classes at the product of keeping airway patency and control breathing at present, but the laryngeal mask volume is big and take position, whole oral cavity, and be a kind of unstable air flue, the foundation that when running into fortuitous event, can not utilize laryngo-pharyngoscopy fast and stablize air flue fast, mainly be to pull out laryngeal mask to carry out tracheal intubation by laryngopharyngeal mirror again, more time-consuming, when performing the operation, women's head-ornaments portion seems more time-consuming and passive, so in case of emergency directly threaten the safety of anesthesia, and bigger throat cover is also bigger to patient's mucous membrane of oropharynx damage; And endotracheal tube is a kind of stable air flue, but because its caliber is thicker, inserting and keeping in the venting process heavier the damage of larynx and tunica mucosa tracheae, especially long period operation postoperative larynx and tunica mucosa tracheae is correlated with and disease incidence rate height, and this conduit stimulates and often makes human body that stronger emergency reaction takes place, and speeds hypertension as heart rate, choking, it is unfavorable the patient that suits the medicine to the illness such as to cough, and need the anesthesia darker than laryngeal mask could allow the patient tolerate in the anesthesia maintenance stage.When the intubate of meeting difficulty can not be inserted often and effectively ventilates, it is passive to bring for Anesthetist's management.
The utility model content:
The purpose of this utility model provides a kind of laryngeal mask type endotracheal tube, it can be realized the function of laryngeal mask airway and keep the purpose of tolerance than light anaesthesia, can in case of emergency need can not import fast and accurately in the conduit again by any equipment, realize complete stability type air flue, can also avoid the conventional laryngeal mask volume bigger, to the compressing damage of mucous membrane of oropharynx.Can avoid conduit to the compressing of larynx and tunica mucosa tracheae damage for common endotracheal tube, and stimulate the stronger stress that is brought and need darker anesthesia and the shortcoming that when difficult intubation, can not set up effective ventilation kept.
In order to solve the existing problem of background technology, this utility model is by the following technical solutions: it is made up of main airway 1, laryngeal mask jacket capsule 2, bullet head 3, fine duct 4; It is provided with two bigger side mouths 5 the main endotracheal tube place of dividing a word with a hyphen at the end of a line, and laryngeal mask jacket capsule 2 is by the high main endotracheal tube front end that holds that holds the more than half portion of low inflation cover capsule of v-shaped structure, plays purpose and bottom compressing esophagus inlet around the sealing larynx more among a small circle; Bullet head 3 is arranged on the main endotracheal tube 1 and the junction of small fine duct 4 foremost, and bullet head 3 is provided with a plurality of apertures 6, is used for breather and inhales expectorant; Fine duct 4 is arranged on the front end of bullet head 3, is convenient to insert under the glottis in the trachea and does not damage mucosa and less to the zest of trachea, can ventilate, inhale expectorant and guide function.
Described fine duct 4 mainly plays a part guide wire, is convenient in case of emergency with in the quick blind slotting importing trachea of laryngeal mask type endotracheal tube.Also can do sputum aspirator tube and inhale expectorant, also can do ventilation and use by air inlet.Because this conduit is tiny also easily to import or easily import by retrograde puncture to the difficult airway intubate time.
The utlity model has following beneficial effect: can realize the function of laryngeal mask airway and keep the purpose of tolerance than light anaesthesia, can in case of emergency need can not import fast and accurately in the conduit again by any equipment, realize complete stability type air flue, can also avoid the conventional laryngeal mask volume bigger, to the compressing damage of mucous membrane of oropharynx.Can avoid conduit to the compressing of larynx and tunica mucosa tracheae damage for common endotracheal tube, and stimulate the stronger stress that is brought and need darker anesthesia and the shortcoming that when difficult intubation, can not set up effective ventilation kept.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Referring to Fig. 1, this specific embodiment by the following technical solutions: it is made up of main airway 1, laryngeal mask jacket capsule 2, bullet head 3, fine duct 4; It is provided with two bigger side mouths 5 the main endotracheal tube place of dividing a word with a hyphen at the end of a line, and laryngeal mask jacket capsule 2 is by the high main endotracheal tube front end that holds that holds the more than half portion of low inflation cover capsule of v-shaped structure, plays purpose and bottom compressing esophagus inlet around the sealing larynx more among a small circle; Bullet head 3 is arranged on the main endotracheal tube 1 and the junction of small fine duct 4 foremost, and bullet head 3 is provided with a plurality of apertures 6, is used for breather and inhales expectorant; Fine duct 4 is arranged on the front end of bullet head 3, is convenient to insert under the glottis in the trachea and does not damage mucosa and expectorant and guide function are ventilated, inhaled to the zest of trachea than I.
Described fine duct 4 mainly plays a part guide wire, is convenient in case of emergency with in the quick blind slotting importing trachea of laryngeal mask type endotracheal tube.Also can do sputum aspirator tube and inhale expectorant, also can do ventilation and use by air inlet.Because this conduit is tiny also easily to import or easily import by retrograde puncture to the difficult airway intubate time.
This specific embodiment can realize the function of laryngeal mask airway and keep the purpose of tolerance than light anaesthesia, can in case of emergency need can not import fast and accurately in the conduit again by any equipment, realize complete stability type air flue, can also avoid the conventional laryngeal mask volume bigger, to the compressing damage of mucous membrane of oropharynx.Can avoid conduit to the compressing of larynx and tunica mucosa tracheae damage for common endotracheal tube, and stimulate the stronger stress that is brought and need darker anesthesia and the shortcoming that when difficult intubation, can not set up effective ventilation kept.
