Description
Technical field
The utility model is related to medical field more particularly to a kind of branchofiberoscope guidance tracheal intubation auxiliary devices.
Background technology
The incidence that difficult airway is intubated in anesthesia is about 2%, and this phenomenon can neither be solved by the means of operation,
Also it is easy to cause more serious respiratory system accident.When encountering difficulties air flue, the past can all use laryngeal mask
Method come substitute special laryngoscope, thyrocricocentesis is driven in the wrong direction guide cannula, light guide blind tracheal intubation etc..But these methods all exist
Certain deficiency.If having to use trachea cannula, can trachea cannula be carried out by using branchofiberoscope
It is a kind of safe and reliable method.Branchofiberoscope guiding row endotracheal intubation is the preferable side for handling known difficulty air flue
Method, damage is light and time-consuming few, oral or nasal can be inserted into, and the stimulation to patient is also small far beyond direct laryngoscope, is particularly suitable for
Bottleneck throat relatively dry is without blood, the patient of non-emergent state, fibrescope handle difficult tracheal intubation success rate about 92% ~
Between 98.5%.But in practical operation, due to the features such as camera lens visual field is small, telescope soft pliable is bent, finds glottis and generally require
For a long time.
Invention content
The purpose of this utility model is that solve the above problem, to achieve the goals above, the technical side of the utility model
Case is：Branchofiberoscope guidance tracheal intubation auxiliary device, including oropharyngeal airway, it is characterized in that：Oropharyngeal airway is curved
Curved, oropharyngeal airway outer ring is C-shaped, and mediastinum is carried in oropharyngeal airway, air injection pipe, gas injection are provided in oropharyngeal airway wall
Pipe side is connect with inflatable cuff, and the air injection pipe other side is provided with gas injection port in one end of oropharyngeal airway.
Described oropharyngeal airway one end is provided with the C-shaped edge of a wing, and the edge of a wing is provided with fixed band.
The injection anaesthetic pipe of perforation oropharyngeal airway is provided in the oropharyngeal airway wall, injection anaesthetic pipe is in oropharynx
The both ends of gas-guide tube are respectively arranged with anaesthetic entrance and anaesthetic nozzle.
The spout of the anaesthetic nozzle is arranged for border.The mediastinum carries venthole.The oropharyngeal airway
It is respectively arranged with anaesthetic entrance in the wall of upper and lower both sides, anaesthetic nozzle is corresponding with respectively in the other end.
The advantages of the utility model, is as follows：The correct allocation method of branchofiberoscope guidance tracheal intubation auxiliary device can
So that the root of the tongue is left pharynx rear wall, release airway obstruction, can feel that patient respiration air-flow is unobstructed, and solves difficult airway in anesthesia
The difficulty of intubation, anaesthetic nozzle can make anaesthetic distribution evenly in this way using border whole distribution outlets, medicament effect
Fruit is more preferable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural scheme of mechanism of the utility model.
In attached drawing：1, air injection pipe；2, the edge of a wing；3, oropharyngeal airway；4, inflatable cuff；5, anaesthetic nozzle；6, side port；7, numb
Medicine entrance；8, fixed band.
Specific implementation mode
This reality of Fig. 1~3 pair oropharyngeal airway is further detailed with novel with reference to the accompanying drawings of the specification：Fiber branch
The correct allocation method of airway wall guidance tracheal intubation auxiliary device can make the root of the tongue leave pharynx rear wall, release airway obstruction, at this time
It can feel that patient respiration air-flow is unobstructed.Oral cavity endocrine, vomitus should be first cleaned when insertion, lifts angle of mandible, and patient keeps
Horizontal position.Method of intubation is divided into two kinds, and one kind is directly placement：The pharynx of oropharyngeal airway with bending part is bent along tongue
Face, which is taken advantage of a situation, to be sent supreme pharyngeal, and the root of the tongue and posterior wall of oropharynx are separated；Another kind is reversed insertion：Oropharynx with bending part is led
Gas-pipe bend is put into oral cavity to palatine upwards（Can first tongue be pushed down with spatula to assist）, when its internal orifice is close to posterior wall of oropharynx（
Pass through uvula）, that is, 180 ° are rotated, the root of the tongue is pushed down in downward push of taking advantage of a situation when by means of patient breaths below bending part, bending
Part resists posterior wall of oropharynx above, is positioned over oral cavity middle position.
Branchofiberoscope guidance tracheal intubation auxiliary device prevents glossoptosis by pushing tongue body, supports arcus glossopalatinus and hangs
Harmony is hung down, to open airway.Inflatable cuff is set to expand by air injection pipe gas injection, and it is dead to reduce the dissection from mouth to bottleneck throat
Chamber.First the tracheal catheter of suitable patient is inserted in branchofiberoscope and is fixed on branchofiberoscope upper end.It is led by tracheae
Pipe guiding channel is placed in branchofiberoscope and tracheal catheter, when being deep into patient oral cavity at about 18 cm, changes fiber branch
The direction of airway wall, finds epiglottis, so that the camera lens front of branchofiberoscope is passed through from the lower section of epiglottis, is found after slightly tilting
Then glottis adjusts branchofiberoscope again, make it into tracheae, reaches in knuckle at about 5 cm, then along fiber
Tracheal catheter is sent in tracheae by bronchoscope, and fixes tracheal catheter, and fiber bronchus is taken out, and gas tube conduit
Air bag.Such as there is apparent cough reflection of choking in the process into mirror or inlet pipe, can be injected by local anaesthetics injection-tube with local anaesthetics, in local anaesthesia
Medicine spout sprays, surface anesthesia, to mitigate bottleneck throat reflection.Tracheae can be guided to insert from branchofiberoscope after being intubated successfully
The side port that pipe auxiliary device side opens exits tracheal catheter, takes out branchofiberoscope guidance tracheal intubation auxiliary device,
It can place in mouth.
After setting pipe success, is intersected around to patient's nape by four fixed bands that the edge of a wing is drawn and fixed.It can also be by fiber branch
The tracheal catheter that airway wall guidance tracheal intubation auxiliary device is closed and planted in oral cavity to prevent patient to sting as bite-block.Fiber branch
The ventilation of airway wall guidance tracheal intubation auxiliary device, attraction channel can assist to carry out pars oralis pharyngis attraction and ventilation.
