Abstract

The present utility model discloses a throat cover with single cavity which includes an air chamber, an air chamber cover and a trachea guide tube that connected together in sequence. It is characterized in that: a triple-connector is disposed at the machine connection end of the trachea guide tube. The present utility model is simple in structure, and can execute the operation such as sputum suction and etc. based on need and not need to pull out the breathing device when keeps the patient's respiration channel smooth by adding a triple-connector, thereby simplifies the operation and lightens the bad influence to the patient.

Description

Novel single chamber 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 laryngeal mask 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.In addition, as shown in Figure 3, the air bag cover body 8 of prior art laryngeal mask combines with the middle part of air bag 1, form bowl type structure, and the place, aperture of airway patient end is designed to fence structure, the purpose of this structure is to reduce the obstruction of epiglottis to passage, can not injure epiglottis again, but this structure has increased the difficulty of mould and processing, and can increase the resistance of ventilation air-flow, reduces the ventilation quality.

Summary of the invention

The purpose of this utility model will solve the defective of existing laryngeal mask airway device, and a kind of novel single chamber laryngeal mask is provided, and makes the operator keeping the patient respiratory passage smoothly on the basis, can inhale operations such as expectorant simultaneously, cuts down finished cost simultaneously, improves the ventilation quality.

The purpose of this utility model is achieved in that a kind of novel single chamber laryngeal mask, includes the air bag, air bag cover body and the endotracheal tube that are linked in sequence, 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.

But described folding interface is provided with check valve and stopper.

The above position of described air bag cover body and air bag neutrality line is connected.

This utility model is simple in structure, by setting up one or three connection-pegs, keeping the patient respiratory passage simultaneously smoothly, just can inhale other operations such as expectorant as required, and need not pull up breathing equipment, has simplified to operate and alleviate harmful effect to the patient.

The specific embodiment

As shown in Figure 1, this utility model comprises air bag 1, passage 2, inflating catheter 3, indication bubble 4, airway tube 5, three connection-pegs 6, check valve 7 and air bag cover body 8.

Air bag 1 inside is communicated with inflating catheter 3, and the port of inflating catheter 3 is provided with indication bubble 4 and check valve 7.

Air bag 1 is connected with the air bag cover body 8 of bowl type, and 2 of the passages of air bag cover body 8 are connected with airway tube 5, the other end of endotracheal tube 5, and promptly the machine link is provided with one three connection-peg 6.As shown in Figure 2, this three connection-peg 6 comprises an interface 61 that is used to connect endotracheal tube 5, but a standard interface 62 and a folding interface 63 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 63, opening part is provided with the stopper 64 of plug-in.But folding interface 63 is in closure state when not using, and prevents gas leakage, when needs are inhaled the expectorant operation, can corkage 64, 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't influence patient's respiration channel this moment.

As shown in Figure 4, best, the above position of air bag cover body 8 and air bag 1 neutrality line is connected, to move on the air bag cover body 8, add the space and the degree of depth of jorum type structure, enough degree of depth make epiglottis can not hinder passage, so just can cancel fence structure, both reduce processing cost, and can increase the area of passage, improved the ventilation quality.
