Abstract

The utility model discloses a novel two-way throat cover for respiratory tract and esophagus, which comprises an air-bag, an air-bag tergite, an endotracheal tube and an esophagus drainage duct and is characterized in that: the mechanical connecting end of the endotracheal tube is provided with three connection-pegs. When in use, the utility model can help user complete operations such as sputum suction while keeping respiratory tract of patient smooth; it simplifies operational procedure and lowers influence on patient, mould design difficulty and production cost; in addition, the utility model also reduces splice cost of tube cavity and the air-bag as well as air leakage risk by improving air-tightness of the air-bag.

Description

Novel air flue esophagus bilateral laryngeal mask
Technical field
This utility model relates to medical instruments field, and particularly a kind of patient who is used for surgery anesthesia, critical patient rescue or other assisted respiartions sets up the medical apparatus and instruments of artificial airway's ventilation.
Background technology
In order to keep unconscious patient respiration ventilation, must set up respiration channel to it.Traditional mode is to use tracheal intubation.But there is big defective in tracheal intubation: at first be to be difficult to fast and suitably pipeline to be inserted trachea, because this is a kind of processing procedure of high-tech very, will be toward contact by devices such as laryngoscopes, therefore must there be the operator of certain technology could implement, just makes this mode in the patient body, set up respiration channel as early as possible and bring a lot of inconvenience with the situation of striving for treatment time (for example critical patient rescue etc.) at some needs; Secondly, tracheal intubation in use easily causes patient's cardiopulmonary reaction, throat pain, cough or laryngospasm etc., and since need control when inserting patient and cervical region, make patient's neck also may come to harm; In addition, insert for convenience, the distal dimension of tracheal intubation must be enough little, and this just makes that the respiration channel that produces is less or narrower.
Laryngeal mask airway device is another new device of setting up respiration channel.Use laryngeal mask airway device more easily to insert and set up respiration channel in the patient body, general operation person just can use through short-term cultivation, and is therefore also very suitable in the occasion of first aid.Because laryngeal mask airway device does not just need to contact with the inner passage of trachea sensitivity can be to patient's lung inflation, so the degree of patient's irriate greatly alleviates, and the respiration channel size of being set up is significantly greater than the respiration channel of being set up by tracheal intubation.Simultaneously, less during owing to insertion, therefore also less to patient's potential injury to the control action at positions such as patient's head, neck.Because above-mentioned advantage, laryngeal mask airway device has become more and more popular since the nineteen eighty-three invention.
But existing laryngeal mask airway device also has its defective: have only one with the interface of breathing equipment, when needs are inhaled operation such as expectorant to patient, must pull up breathing equipment, influenced the smooth and easy of respiration channel; Air bag adopts silicone rubber mostly, the air bag tergite then is thin silicone rubber plate, communicate with air bag inside, insert throat's inflation back expansion and form elastomer, fit with cavum laryngis, play sealing function, prevent that gas leaks in respiratory from the slit of laryngeal mask and cavum laryngis, but because the air-tightness of silastic material is relatively poor, and the technique for sticking requirement is high, and bonding bad very easily gas leakage is after gas in the air bag is revealed from the tergite position, this sealing function will be had a greatly reduced quality, and causes respiration channel to set up failure.
Summary of the invention
The purpose of this utility model is the defective that will solve existing laryngeal mask airway device, and a kind of novel air flue esophagus bilateral laryngeal mask is provided, and makes the operator keeping the patient respiratory passage smoothly on the basis, can inhale operations such as expectorant simultaneously, and air-tightness is good.
The purpose of this utility model is achieved in that a kind of novel air flue esophagus bilateral laryngeal mask, includes air bag, air bag tergite, endotracheal tube and esophagus drainage catheter, and it is characterized in that: the machine link of described endotracheal tube is provided with one three connection-peg.
Described three connection-pegs comprise that one connects the interface of endotracheal tube, but one connects the standard interface and a folding interface of respirator.
Described standard interface laterally is located at three connection-peg sides.
But described folding interface is provided with check valve and stopper.
Described airway tube and esophagus drainage catheter are that straight line is set up in parallel.
Described air bag tergite is a foamed silastic piece.
This utility model in use, can make the operator keep the patient respiratory passage simultaneously smoothly, inhale operations such as expectorant, step simplifies the operation, reduction is to patient's influence, and can reduce the difficulty and the production cost of mould design, in addition, also reduce the bonding cost of tube chamber and air bag and the risk of gas leakage, improved the air-tightness of air bag.

Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model three connection-pegs;
Fig. 3 is the connection diagram of this utility model air bag and air bag tergite.
The specific embodiment
As shown in Figure 1, this utility model is a kind of novel air flue esophagus bilateral laryngeal mask, includes air bag 1, esophagus drainage catheter mouth, gas tube 3, indication bubble 4, airway tube 5, esophagus drainage catheter 6, bite-block, three connection-pegs 8, check valve 9 and air bag tergite 10 etc.
Air bag 1 inside is communicated with gas tube 3, and the port of gas tube 3 is provided with indication bubble 4 and check valve 9.
Air bag tergite 10 is connected with air bag 1.The other end of endotracheal tube 5, promptly the machine link is provided with one three connection-peg 8.Three connection-pegs 8 comprise an interface 81 that is used to connect endotracheal tube 5, but a standard interface 82 and a folding interface 83 that is used for interspersed other suction catheters that is used to connect respirator as gas inlet-outlet.But be provided with check valve in the folding interface 83, opening is provided with the stopper 84 of plug-in.But folding interface 83 is not in closure state when not using, and prevents gas leakage, when needs are inhaled the expectorant operation, can unstop 84, sputum aspirator tube is inserted endotracheal tube 5 and enters trachea by check valve, inhale the expectorant operation, it is smooth and easy that can not influence patient's respiration channel this moment.And owing to adopted three connection-pegs, greatly reduce the design and the production cost of double lumen tube, because the interface of prior art and breathing apparatus be with the airway tube of laryngeal mask in the same way, because the breathing apparatus interface has certain step, airway tube and esophagus drainage catheter must have certain clearance, could make things convenient for and being connected of breathing apparatus, make the design of airway tube must have certain curving degree just can realize like this, this has just increased the difficulty and the production cost of mould design.But adopt three connection-pegs, 8 backs just can address this problem, be located at three connection-pegs, 8 sides because the standard interface that is connected with breathing apparatus 82 is horizontal, airway tube 5 just can be set up in parallel by straight line with esophagus drainage catheter 6 like this, does not also influence the operation of connecting duct.
Air bag tergite 10 adopts foamed silastic piece in aggregates, and it expands flexible naturally, and need not inflate, and is bonding easy, so both can play the effect of sealing, can avoid the risk of air bag from tergite gas leakage again.
