Abstract

The utility model discloses a guidable throat ventilation conduit which comprises a hollow soft ventilation conduit (1). The utility model is characterized in that the front end of the ventilation conduit is sealed and a minor air sac (2) is arranged near the sealed end. The front wall of the conduit approaching to the air sac is provided with a vent hole (3) above which a large air sac (4) is arranged. An air sac charging port (5) is arranged on the wall of the ventilation conduit. In addition, the utility model is also provided with a guide iron core (6) and a soft guide tubule (7), wherein the guide iron core (6) can be inserted in the guide tubule (7), is arranged in the ventilation conduit (1) penetrates out from the vent hole of the front wall of the ventilation conduit (1), and is used when the conduit is difficult to insert. The utility model is convenient in use, and an unprofessional person can utilize the utility model to establish an air passage. The utility model can be used for keeping the air conduit for small operation without need of loosening muscles, and can also be used for firstly keeping ventilation and then guiding an intubation tube when the conduit is difficult to insert. The utility model can also be used for assisting a fiber support mirror and a light emitting air pipe to guide a core intubation tube.

Description

A kind of trachea pipe of guiding

Technical field

This utility model relates to a kind of trachea pipe of guiding, and especially relates to a kind of guided trachea pipe that two air bags can be set up throat oxygen supply passage fast that has.

Background technology

At present, the oxygen supply passage comprises common endotracheal tube and laryngeal mask, both oxygen supply of all can pressurizeing.Endotracheal tube needs to insert in the trachea by laryngoscope, and laryngeal mask then needs it is buckled on the position of larynx, and aforesaid operations all needs to be finished by the professional.When running into difficult intubation, even the professional also needs to take a long time and could set up airway.And in the first aid process, bad or when breathing no more, first thing that will do set up airway exactly when patient respiration, it is slow to can't permit a moment, otherwise might cause serious consequence.Therefore, existing oxygen supply passage usually brings inconvenience to rescue service.

The utility model content

The purpose of this utility model is to overcome the above-mentioned defective of existing oxygen supply passage, and a kind of simple and easy to do the guided trachea pipe that can set up throat oxygen supply passage fast is provided.

The purpose of this utility model is achieved through the following technical solutions: it comprises a soft airway of hollow, it is characterized in that, described airway front end sealing, be provided with the air bag that esophagus is sealed in less being used near the blind end place, the conduit antetheca that is right after this air bag is provided with a passage, the passage shape is preferably oblong, and this passage top also is provided with the air bag that pharyngeal cavity is sealed in bigger being used to, and also is provided with the airbag aeration mouth on the described airway wall.This utility model is provided with guiding iron core and soft guiding tubule in addition, described soft guiding tubule can be made of suitable flexible plastic control, the guiding iron core is made by a thin wire, the guiding iron core can insert in the guiding tubule, again its not blind end from airway is put into airway, and pass from the antetheca passage of airway, use when being used for difficult intubation.

Airway is inserted into 20-24cm the esophagus from the oral cavity,, listens the respiratory murmur of chest behind the manual ventilation two airbag aerations, if respiratory murmur is well then fixing, badly then advance again inward or pull out 1-2cm outward, determine whether to put in place according to respiratory murmur again, can connect breathing bag or breathing machine ventilation after putting in place.

This utility model inserts in the esophagus, fills up the ballonet of breather antetheca passage below, and with esophagus closed, the air vesicle with this passage top fills up simultaneously, and bottleneck throat promptly becomes a closed chamber, and the antetheca passage by pipeline gets final product oxygen supply.From medical science clinically, it is simple that tube is inserted esophagus, behind two airbag aerations up and down with airway antetheca passage is practicable manual control or mechanical ventilation, and guides tracheal intubation near can utilizing airway antetheca passage harmony door opening.

When difficult intubation, need the common endotracheal tube intubate of guiding, can be inserted into the guiding iron core in the guiding tubule this moment, put into airway again, pass from the antetheca passage of airway, airway is in place, trigger epiglottis with the front end of guiding tubule and maintain static, to guide the tubule propelling of taking advantage of a situation again forward, patient has to choke and coughs expression and enter trachea.

Airway is withdrawed from,, insert common endotracheal tube to be with the guiding tubule of guiding iron core as guiding.

This utility model is simple in structure, and is easy and simple to handle, when the professional who is familiar with intubation technique not when first aid is on-the-spot, can utilize it to set up airway by remaining medical worker; For not needing the loose one's grip short and small operation of art of flesh, can be in order to keep airway; When also can be used for difficult intubation, keep ventilation earlier, again row guiding intubate.

This utility model still can be used for assisting fibre bronchus mirror and luminous trachea guiding core intubate.

Description of drawings

Fig. 1 is the airway structural representation of this utility model one embodiment;

Fig. 2 is guiding iron core and a guiding tubule sketch map embodiment illustrated in fig. 1;

Fig. 3 puts into the guiding tubule for the iron core of will guiding embodiment illustrated in fig. 1, will guide after tubule passes from the antetheca passage of breather line again, and part advances the sketch map of guiding tubule.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to accompanying drawing: present embodiment comprises a hollow flexible plastic conduit 1, the front end sealing of described conduit 1, be provided with the air bag 2 that is used to seal esophagus of a girth 3cm at distance blind end 2cm place, conduit 1 antetheca that is right after air bag 2 is provided with the long oblong passage 3 of a 2.5cm, passage 3 tops also are provided with the air bag 4 that is used to seal pharyngeal cavity of a girth 5cm, also are provided with airbag aeration mouth 5 on described airway 1 wall.In addition, also be provided with guiding iron core 6 and soft guiding tubule 7, described soft guiding tubule 7 usefulness flexible plastic pipes are made, guiding iron core 6 is made by a thin wire, guiding iron core 6 can insert in the guiding tubule 7, put into airway 1 from the not blind end of airway 1 again, and pass, use when being used for difficult intubation from the antetheca passage 3 of airway 1.
