Description

Uplifting throat organizer and device for difficult airways

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to lift throat organizer and be used for device of difficult air flue.

Background

A difficult airway is a clinical situation where an anesthesiologist with more than five years of anesthesia experiences difficulty in mask ventilation or tracheal intubation.

"the patient will die only from the failure of ventilation and will not die from the failure of intubation", in clinic, once the ventilation is difficult, the patient is easy to enter the anoxic state to cause the death by asphyxia. The prior art solutions for difficult ventilation and the existing drawbacks are mainly as follows:

(1) placing into a nasopharyngeal airway for pressurization and ventilation: but some patients still cannot improve ventilation due to obesity, pachynsis of soft palate or tongue body, overlong nasal passage, obstruction of posterior nasal orifice and poor position of nasopharyngeal airway;

(2) placing the artificial trachea cannula into supraglottic ventilation tools such as an oropharynx air passage, a laryngeal mask, an esophagus-trachea combined catheter, a laryngeal tube and the like for pressurizing and supplying oxygen: however, the device needs to be placed in an opening degree of about 2-3 cm, and cannot be placed in patients with openings smaller than 2cm, 1cm and 0.1 cm; even if the tool is placed into a patient with partial unrestricted mouth opening, the clinical situation that the ventilation cannot be improved due to obesity, the fat soft palate or tongue body, the overlong or overlong neck length, the poor placement position and the like can also occur;

(3) another tracheal intubation: although the method has a little success rate, the defect that the laryngoscope cannot be placed still exists in the patient with limited opening, and the patient who does not meet the intubation condition is forcibly intubated, so that the clinical situations which are also dangerous to life, such as larynx spasm, bronchospasm and the like are easily induced.

(4) Emergency cricothyroid membrane puncture catheterization or tracheotomy: the method is an invasive method, is easy to damage the air passage, causes serious sequelae, and still has the defects of puncture or incision failure and long time consumption.

(5) The visual ventilation laryngoscope (patent number: 201220117131.4) granted by the national intellectual property office of the people's republic of China and the visual ventilation intubation laryngoscope (patent number: 201210417431.9) granted by the invention patent have the following defects: firstly, the ventilation of the two is realized through a ventilation handle, the ventilation handle comprises a ventilation tube cavity and a visual structure, the handle is required to have a certain thickness which is about 2.5-3 cm, the difficult ventilation condition of a part of patients with normal or slightly limited opening degree is only solved, and the ventilation handle cannot play a role because the ventilation handle cannot be placed in the patients with difficult ventilation with limited opening degree (such as the opening degree is less than 2cm, 1cm and 0.1cm) and tumor or foreign body occupation in the mouth; and both can only ventilate through the oral cavity, can not ventilate through the nasal cavity. Secondly, the former (patent No. 201220117131.4) still has the problem that the connection between the mask and the handle is relatively stiff and the mobility is small, the change of the handle position can be adjusted according to the pharyngeal exposure condition in clinical application, the change of the handle position can lead the mask to generate close following linkage such as upwarp and offset, and the like, thereby further causing the defects that the mask can not be tightly attached to the face of a patient and serious air leakage and even failure of ventilation, and the former has the problem that the mask can not be subjected to oral or transnasal tracheal intubation during ventilation. Thirdly, in the latter (patent No. 201210417431.9), because the ventilation is carried out by closing the oropharyngeal cavity with the air bag, when the closed air bag is positioned in the pharynx, the ventilation and the tracheal intubation can not be carried out simultaneously by the air bag which plays a role of closing the oral cavity or the nasal trachea intubation; if the closed air bag is not positioned in the pharynx and is only positioned in the mouth, the defect that the air pressurized into the oropharyngeal cavity overflows out of the nose through the retronasal hole exists.

In addition, in the existing difficult airway treatment scheme, for a patient with severely limited opening, a technical scheme of guiding the lower trachea cannula by a conscious fiberoptic bronchoscope is selected. The trachea cannula in the waking state is a very feared physical and psychological experience for patients, can cause huge fluctuation of hemodynamics, and even can endanger life due to cardiovascular and cerebrovascular accidents. Currently, for patients with restricted ostia and no predicted ventilation, a few physicians attempt to induce bronchofiberscope-guided transnasal intubation of patients with diminished respiration and with rapid sequential general anesthesia. The intubation scheme can increase pharyngeal cavity space within a certain range by means of the lower jaw support to improve glottic exposure, but has limited help for patients with small lower jaw, serious tongue body falling back and thick, loose and collapsed pharyngeal soft tissues, and the implementation of the operation scheme is carried out in a patient deoxygenation state, and if the glottic exposure time is too long or the exposure fails, suffocation and death of the patients can occur. Therefore, difficult fiberoptic bronchoscopic endotracheal tubes lack a means to increase the exposure of the pharyngeal cavity to a patient with restricted stoma.
