Description

The tracheal intubation Pharynx trachea

Technical field

This utility model relates to medical medical instruments field, is specifically related to the tracheal intubation Pharynx trachea that a kind of clinical ventilation is used.

Background technology

With regard to the tracheal intubation of branchofiberoscope guiding, the per nasal path is easier to, this is because narrow nasal cavity has certain support and guiding function to FOB, FOB also is easier to find epiglottis and glottis after going out choana, the per os path is difficulty, and is larger due to the pars oralis pharyngis space, is difficult for placed in the middle and amesiality when FOB inserts, need advance and retreat repeatedly, adjust the position of FOB front end and seek glottis.At present existing several special-purpose oropharyngeal airways can be used for assisting FOB to carry out the oral trachea cannula operation; when inserting these Special ventilatings road; can not only protect FOB to exempt from biting of patient, and can also keep respiratory passage unblocked and tongue is removed from pharyngeal, FOB is near glottis in guiding.Clinical experience shows, the safety of using these Special ventilatings roads can obviously shorten the operating time of FOB tracheal intubation and improve the patient; At present there are Berman tracheal intubation Pharynx trachea, Williams airway-trachea intubation device and Ovassapian tracheal intubation breather in commonly used tracheal intubation Special ventilating road.

Berman tracheal intubation Pharynx trachea also claims II type airway.Conventional oropharyngeal airway be can not only be used as, and auxiliary per os blind tracheal intubation or the operation of FOB oral trachea cannula can be used for.The total length of this passage is a cylinder structure, can insert through satisfied lubricated endotracheal tube.Present this kind airway is totally 3 available models.When this type of airway of correct insertion suitable types, correct before it and be positioned at epiglottic vallecula, and tongue can be lifted forward.The tube wall of one side of this airway is disconnected shape, and slit therebetween can be increased, thereby but moves lower this breather after tracheal intubation operation on endotracheal tube completing.

The main purpose of design Williams airway-trachea intubation device is for the operation of per os blind tracheal intubation, also can be used as conventional oropharyngeal airway or is used for the operation of FOB guidance tracheal intubation.This type of breather of at present clinical practice has two kinds of models: No. 9 and No. 10, can mate respectively the endotracheal tube of internal diameter≤8.0mm and≤8.5mm.Its pharynx curved proximal end 1/2 in a tubular form, be used for placing FOB and endotracheal tube; The lingual surface of far-end 1/2 is open shape.In the operation of tracheal intubation, answer the joint of removal endotracheal tube, because it can not pass the tube chamber of this breather, after completing, tracheal intubation can hinder this airway of removal from the endotracheal tube.

Ovassapian tracheal intubation breather is mainly used in the operation of FOB guidance tracheal intubation, and the lingual surface of its near-end is quite wide, is flat, is beneficial to control the position of tongue, and the two side is vertical configuration.The guiding wall that two pairs of bendings are arranged between the two side, its gap can be passed through the endotracheal tube of internal diameter≤9.0mm smoothly.The guiding wall of this airway belongs to flexibility, can be with airway removal from the endotracheal tube.1/2 of this kind airway near-end is tubular structure, and its function class is similar to bite-block, far-end 1/2 without rear wall, be beneficial to the FOB operation.When adopting this kind airway to advance the FOB guidance tracheal intubation, needn't remove the joint of endotracheal tube.

Yet, in the practice of clinical anesthesia, although some cases uses and changed this type of tracheal intubation breather of different models, the tracheal intubation failure of FOB guiding appears still.One of them reason is because epiglottis has hindered advancing of FOB, when epiglottis bigger than normal partially long or its on lift function when poor, because the epiglottis front end is sagging near the pharynx rear wall, FOB is advanced is obstructed; Another reason is when the pharyngeal textural anomaly of patient, and in a single day the tubular structure opening of Berman or Williams Pharynx trachea front end can not aim at glottis section, occurs departing from the time of may making FOB go out the breather front end, can't find glottis.

The basic configuration of this device is similar to Berman or Williams tracheal intubation Pharynx trachea, all in tubular construction, therefore it has kept the function of conventional oropharyngeal airway, also keep simultaneously support and guiding function to the operation of per os blind tracheal intubation and the operation of FOB guidance tracheal intubation, moreover, this installs slidably the first half has similar common laryngoscope and lifts the function of epiglottis to the front upper place, in addition, the dismountable structure of its up and down two parts helps it after the tracheal intubation success, promptly separates with endotracheal tube.

The utility model content

The purpose of this utility model is a kind of tracheal intubation Pharynx trachea that satisfies clinical various situations that designs in order to address the above problem.

This utility model solves the technical measures that its technical problem takes:

The tracheal intubation Pharynx trachea, mainly formed by upper tube half, lower tube half two parts, it is characterized in that upper tube half grows 1cm than lower tube half far-end, upper tube half is provided with chute and the projection corresponding with chute with lower tube half near-end inboard, upper tube half is provided with the gap, separates up and down with lower tube half far-end end, upper tube half, lower tube half head end are provided with " T " type joint, and " T " type joint is provided with elastic bandage.

The beneficial effects of the utility model are: when 1, grasping (FOB) operation by branchofiberoscope, hereinafter to be referred as FOB, minute Pharynx trachea is to front slide, move above can making tip forward, help to raise sagging epiglottis, appear glottis, and increase the FOB working place; 2, the latter half Pharynx trachea is motionless simultaneously to front slide for the first half Pharynx trachea, the open-ended shape of breather and size are changed, make FOB in the activity space increase in Pharynx trachea exit, near glottis section the time, the increase of this working place is conducive to FOB and finds and insert glottis; 3, the dismountable sliding groove structure of Pharynx trachea up and down two parts helps it after the tracheal intubation success, separates with endotracheal tube rapidly; 4, T-shaped projection, be used for fixing after neck the elastic bandage in a week, be conducive to Pharynx trachea position fixing in the oral cavity.
