Description

Tracheal intubation device for difficult airways

Technical Field

The utility model relates to the field of trachea, in particular to a trachea cannula device for difficult airways.

Background

The incidence of difficult airways in the practice of endotracheal intubation is as high as 2% to 3%, whereas in these cases, patients who are fatal due to difficult airways are as high as 70%. The conventional method for clinically treating the difficult airways mainly comprises the modes of applying a fiberbronchoscope, an esophagus and trachea combined catheter, a laryngeal mask, cricothyroid membrane puncture, tracheotomy and the like.

In particular, when intubation is performed, the oral, pharyngeal and laryngeal axes of a patient are required to be kept at the same level so as to enable the glottis of the patient to be fully exposed, but the patient often shows larger stress response, so that hemodynamic fluctuation is caused, and adverse reactions are extremely easy to occur. When the view is limited or glottis is difficult to reveal, the tracheal intubation time is often long, and repeated forced exposure can also damage the throat mucosa of the patient.

In order to solve the problems, the laryngeal situation can be observed through the display screen, but the display of a patient with a thinner pharyngeal cavity is often unclear, the stimulation response is larger, and the injury is easy to cause, so that the tracheal intubation can be realized by guiding by adopting the guiding device, however, the adaptation of the bending shape of the trachea to the self-adaptive change and shaping is difficult to be carried out by adopting the simple guiding device, and the laryngeal intubation is particularly suitable for the situation with a thinner pharyngeal cavity.

1-4, in one embodiment of the present utility model, there is provided an endotracheal intubation device for a difficult airway, comprising:

the hollow pipeline 100 comprises a plastic shaping pipe section 110 and a hose section 120 which are sequentially arranged in sequence, wherein the front end of the inside of the plastic shaping pipe section 110 is provided with a light-emitting part 130; the hollow tube 100 is configured to move the plastic shaped tube segment 110 along the pharyngeal cavity and through the glottis to place the airway when a stent is placed and expands the pharyngeal cavity, and to move in reverse and exit the pharyngeal cavity with the stent after the endotracheal tube 300 is placed in the airway;

the tracheal tube 300 is pre-sleeved on the hose section 120 and can move along the length direction of the hollow pipeline 100, and the tracheal tube 300 is configured to move from the hose section 120 to the front end of the plastic shaping pipeline section 110 when the plastic shaping pipeline section 110 is placed in the air passage, so that the plastic shaping pipeline section 110 is placed in the air passage.

The tracheal catheter 300 used by a normal adult has a diameter of 6.5-7.5mm, and when the patient encounters a difficult airway, the airway is difficult to be placed, so that auxiliary guiding placement is required. Specifically, in the embodiment shown in fig. 1, when laryngoscope 210 is used as the expansion device, laryngoscope 210 is placed in position to expand the pharyngeal cavity by pressing the jaw against pressure plate 211, and plastic shaped tube segment 110 is manipulated to move along the pharyngeal cavity and through the glottis to be placed in the airway; the lens 212 at the front end of the laryngoscope 210 can be operated to shoot the image of the pharyngeal cavity and transmit to the display screen 213 outside the oral cavity, so that the insertion condition of the hollow tube 100 can be observed by using the laryngoscope 210, and when the luminescence of the luminescence part 130 can be seen at the neck, the guiding device is indicated to enter the complete airway; then, the tracheal tube 300 is moved from the hose section 120 to the front end of the plastic shaping tube section 110, so that the tracheal tube is placed in the airway; the hollow tube 100 moves in the opposite direction and exits the pharyngeal cavity with the laryngoscope 210, completing the procedure.

When the patient has been mechanically ventilated during surgery using laryngeal mask 220, i.e., in the embodiment shown in figure 2, placement of laryngeal mask 220 fully expands the pharyngeal cavity, while mask body 221 at the forward end of laryngeal mask 220 just covers the glottis. In this case, the endotracheal tube 300 is placed, the plastic shaped tube segment 110 is manipulated to penetrate the laryngeal mask 220, move along the pharyngeal cavity and through the glottis to be placed in the airway; when the plastic shaped tube section 110 is inserted to a preset position, the luminescence of the luminescence part 130 can be seen at the neck, indicating that the guiding device has completely entered the airway; laryngeal mask 220 is then removed and endotracheal tube 300 is moved from hose segment 120 to the forward end of plastic shaped tube segment 110 for placement in the airway; finally, the entire hollow tube 100 is moved in the reverse direction and exits the pharyngeal cavity, completing the procedure.

In addition, oropharyngeal airway 230 may be used to assist in intubation during patient wakefulness, as shown in the embodiment of FIG. 3. Specifically, the oropharynx airway 230 is placed in the mouth of the patient, the placement of the oropharynx airway 230 expands the pharyngeal cavity, and then the plastic shaped tube segment 110 is operated to pass through the oropharynx airway 230, move along the pharyngeal cavity and pass through the glottis to be placed in the airway; when the plastic shaped tube segment 110 is inserted to the preset position, the light emitting member 130 is visible in the neck, indicating that the guiding means has been completely entered into the airway; then the oropharyngeal airway 230 is removed and the endotracheal tube 300 is moved from the tube segment 120 to the front end of the plastic shaped tube segment 110, thereby being placed into the airway; finally, the entire hollow tube 100 is moved in the reverse direction and exits the pharyngeal cavity, completing the procedure.

The embodiment is particularly suitable for intubation operation under the condition of narrow throat space, and the embodiment is combined with the pharyngeal cavity expanding device, so that the success rate of intubation can be improved, and damage can be reduced. On the one hand, the hollow pipeline 100 is utilized, the plastic shaping pipe section 110 at the front part has good plasticity, can adapt to the bending shape of the air passage to carry out self-adaptive shape change and shaping after stretching into the air passage along the pharyngeal cavity, is easier to put into a thinner air passage, can reduce the throat mucosa of a damaged patient, and combines the laryngeal mask 220 or the laryngoscope 210 to synchronously expand the air passage, thereby providing convenience for the smooth putting in of the plastic shaping pipe section 110 and further reducing the damage to the air passage; the front end of the plastic shaping pipe section 110 is provided with the light-emitting component 130, the degree of the plastic shaping pipe section 110 entering the trachea is observed by utilizing the principle of light transmission of neck soft tissues, so that the progress of blind probe intubation can be monitored, damage caused by position deviation of intubation can be avoided, and doctors can know the progress and condition of the plastic shaping pipe section 110; the hose section 120 of the hollow pipe 100 is used for presetting the tracheal catheter 300, and is convenient for hand-held driving;

on the other hand, the laryngeal mask, the oropharynx airway or the laryngoscope can expand the airway, so that the probability of injury of the cannula to the throat mucosa of a patient after the airway is expanded is reduced, and the probability of stimulation and stress reaction is also reduced.

The designed hollow pipeline 100 is convenient for forming a larger pipe diameter, ensures that the plastic shaping pipe section 110 has stronger supporting force in the process of extending into the air passage, and avoids the insertion failure caused by large-angle bending due to unexpected collision with the air passage;

referring to FIG. 4, in some embodiments, the plastic shaped pipe segment 110 has a length L1 of 38-42cm and the hose segment 120 has a length L2 of 28-32cm. Specifically, the plastic shaping pipe section 110 is longer, the length L1 is about 40cm, and the plastic shaping pipe section can adapt to the length of the pharyngeal cavity and the airway of a human body; the length L2 of the tube section 120 is about 30cm, which is basically consistent with the length (30 cm) of the pre-sleeved tracheal catheter 300, and is convenient for hand-held driving.

Referring to fig. 4, in some embodiments, the hollow conduit 100 has a diameter of 4.5-5.5mm. Specifically, the hollow pipe 100 has a larger pipe diameter, but cannot be too large, the probability of touching the sound track can be increased by exceeding 5.5mm, meanwhile, the pipe diameter of the hollow pipe 100 cannot be too small, the plastic shaping pipe section 110 is guaranteed to have stronger supporting force in the process of extending into the air track, the pipe insertion failure caused by large-angle bending due to smaller diameter after the plastic shaping pipe section 110 accidentally touching the air track is avoided, and therefore the diameter of 4.5-5.5mm is a more proper size.

Referring to fig. 4, in some embodiments, a plastic metal strip 140 is disposed in the plastic shaped pipe section 110 along the length direction, the plastic metal strip 140 is an aluminum strip or a copper strip, and the diameter of the aluminum strip or the copper strip is 1.5-2.5mm. The aluminum strips or copper strips with the diameters of 1.5-2.5mm have strong plasticity, can adapt to the bending shape of the air passage to carry out self-adaptive shape change and shaping after extending into the air passage along the pharyngeal cavity, are easier to be placed into a thinner air passage and can reduce the throat mucous membrane of a damaged patient; meanwhile, the aluminum strip or the copper strip made of metal has a certain supporting degree, so that the plastic shaping pipe section 110 is guaranteed to have a strong supporting force in the process of extending into the air passage, and the problem that the intubation fails due to large-angle bending caused by too soft air passage is avoided. It should be noted that if the diameter is less than 1.5mm, the supporting force of the plastic shaped pipe section 110 is difficult to ensure, and if the diameter is more than 2.5mm, the plasticity of the plastic shaped pipe section 110 is lowered, and the effect is not as expected.

Referring to fig. 4, in some embodiments, the light emitting component 130 includes a red light diode 131 and is connected to an external power source 133 by an electrical connection 132, and the electrical connection 132 is disposed through the plastic shaped pipe section 110 and the hose section 120. Specifically, the red light emitted by the red light diode 131 has good light transmittance, and more obvious outward light emission through the soft tissue of the neck, so that a doctor can observe the degree of the plastic shaping pipe section 110 entering the trachea from the outside conveniently, the process of blind probing the cannula is controllable, the damage caused by the position deviation of the cannula is avoided, and convenience is brought to the doctor in knowing the progress and the condition of the placement of the plastic shaping pipe section 110.

Of course, besides the red diode 131, other light emitting components 130 may be adopted, the external power source 133 may be plugged into or magnetically attached to the electrical connection wire 132 to realize docking and rapid disassembly, and even the light emitting components 130 may not need the external power source 133 to generate power, which is not limited herein.
