Description
Technical field
The present embodiments relate to air flue tube ejector technical fields, and in particular to a kind of visualization air flue tube ejector.
Background technique
It is routine clinical using the double pulmonary ventilation of trachea cannula when patient needs to carry out mechanical ventilation in clinical position.Or
Unilateral lung closure, one-lung ventilation two ways are carried out when row thoracic surgery.Tracheal catheter has been widely used in patient's assisted ventilation
Important air flue tool, can quickly, effectively establish artificial airway.However, due to human anatomic structure complexity and air flue
The difference of mucous membrane tolerance, frequently resulting in air flue mucosa injury, difficult intubation and the displacement of tracheae interior tracheae catheter tube causes to lead to
The appearance for the problems such as gas is bad or even conduit deviates from tracheae, eventually leads to ventilation failure, or even cause the Complicated with Severe such as asphyxia
Disease.In addition, traditional trachea cannula, double-cavity bronchial cannula and bronchial occlusive device in venting process cannot to patient into
Promoting the circulation of qi road visualized management such as needs to adjust the depth or orientation of tracheal catheter in clinical position, often due to naked eyes can not can
See, therefore tracheal catheter belongs to blind spy operation in endotracheal adjustment process, cause to air flue and its accessory structure such as glottis,
The damage of articulatio cricoary tenoidea etc. or even irreversible physiological structure destroy, and waste time, and patient's hypoxic exposure is caused to prolong
Length even delays patient's rescue time.Its main cause is as follows:
Firstly, endotracheal intubation is as general anesthesia operation or CPR and with the Severe acute disease of respiratory dysfunction
Important vent method used in patient's rescue process carries out in endotracheal intubation in routine clinical, how to improve oral straight
Depending on the success rate of lower trachea cannula and difficult airway intubation, and shortening intubation time, reducing is current clinic to the damage of air flue
The critical issue faced in work.In clinic, if the air flue patient that meets difficulty needs replacing tracheal catheter or division of chest disease suffers from
When person is changed to single-lumen bronchial tube by double-lumen catheter, through frequently with changing pipe device as guiding tool, i.e., first
Be inserted into the tracheal catheter of air flue be inserted into it is thinner change pipe device, then the tracheal catheter being inserted into is extracted to body along changing pipe device
Outside, after pipe device is changed in the external disengaging of extraction, new tracheal catheter is inserted in and changes pipe device, conduit is placed in by conduit along the path for changing pipe device
In air flue, it finally is placed in trachea cannula under the guidance for changing pipe device, achieve the purpose that guide Trachea cannula or changes pipe.Traditional
Changing pipe device, to be that a modeling system flexible, without scale is solid lead core, and main function is that guiding tracheal catheter merging is intratracheal,
But after tradition changes the merging of pipe device, operator changes the merging process of pipe device due to can not intuitively see, is unable to judge accurately
Whether the placed-depth for changing pipe device is located at intratracheally, punctures gas with the presence or absence of changing pipe device front end when can not judge to change the merging of pipe device
The case where tube wall, is unable to ensure during pipe device replacement tracheal catheter is changed in use and changes pipe device and do not deviate from air flue, causes to be placed in gas
The failure of pipe conduit.
Secondly, double-lumen catheter be widely used in as a kind of non-visualization airway pressure device it is auxiliary in division of chest disease's patient's art
The important tool of mechanical ventilation is helped, is placed in double-lumen catheter in art, the sick side Fei Hejian side lung of patient can be isolated and be separated,
To prevent disease side pulmonary secretions and pathogen from sending out to strong side lung, cause acute respiratory obstruction or the strong infected danger of side lung
Danger.Double-lumen catheter can realize the single lung independence or synchronized ventilation of pulmonary surgery or urgent patient in thoracic cavity, be good for side lung in art
One-lung ventilation, Ipsilateral lung pause ventilation, to meet needs of performing the operation in art.Art Bi Hangshuan pulmonary ventilation, not to avoid postoperative lung
It opens, lung collapses.Clinical double-lumen catheter implantation operation is more complex, needs a large amount of clinic, is currently to have in clinical position
Effect establishes lung's isolation ventilation, the standard vent method of one-lung ventilation.However, double-lumen catheter traditional in clinic
Main body tube sectional area is thicker, and without visual probe, traditional double-lumen catheter blind tracheal intubation process damage is larger, may cause sound
Door physiological anatomic architecture destroys, and tracheal wall scratches, or even tearing, causes bad clinical adverse events.In addition, two-chamber tracheae is led
Pipe exists in clinical position to the external force pressure of tracheae due to its thicker outer diameter, thus after merging maintenance process and
During tube drawing, it be easy to cause and patient airway's external force pressure is damaged.
Conventional tracheal intubation i.e. existing in the prior art, double-cavity bronchial cannula etc. in non-visualized operation,
Airway damage, and the problem of position inaccurate.
Summary of the invention
For this purpose, the embodiment of the present invention provides a kind of visualization air flue tube ejector, to solve biography existing in the prior art
System changes pipe conduit, double-lumen catheter etc. in non-visualized operation, Airway damage, and the problem of position inaccurate.
