Abstract
The invention relates to a leading-in device for giving a tracheal cannula through a laryngeal mask. A problem that an artificial airway is established for patients with difficulty in tracheal intubation when the laryngeal mask cannot be kept in use for a long time can be effectively solved. First airbags are mounted at the left end of a guide wire; the first airbags are communicated with a second airbag at the right end of the guide wire through airways; the second airbag is communicated with a valve mouth at the right end part of the guide wire; at least three first airbags are arranged and uniformly distributed on the three side walls of the guide wire in the circumferential direction of the guide ire; and the first airbags are communicated with one another through connecting tubes. The leading-in device for giving the tracheal cannula through the laryngeal mask, provided by the invention, is simpler in operation, easier to learn and more time-saving than a fiber bronchoscope when used for transition between the laryngeal mask and the tracheal cannula and is particularly used for patients with difficulty in tracheal intubation; during the transition period, the airways are always kept in an open state through the adoption of the design of the airbags; and the external diameter of the guide wire allows the tracheal cannula with smaller type to be smoothly inserted.
Description
Technical field
The present invention relates to medical apparatus and instruments, particularly a kind of gatherer through tracheal cannula through laryngeal mask.
Background technology
At present, the mode setting up artificial airway that emergency treatment is commonly used clinically, routine has two kinds: laryngeal mask and tracheal intubation.General use tracheal intubation, but for the patient of difficult intubation, the chance of application laryngeal mask is more, but laryngeal mask is due to Problems existing in structure, long-time reservation use can cause serious laryngeal edema, and not easily fix, so when need set up the artificial airway of long period, still to endotracheal intubation be replaced by.When changing, carrying out endotracheal intubation again if first laryngeal mask is extracted, a lot of time can be wasted.And if endotracheal intubation is unsuccessful, still needs temporarily more to gain laryngeal mask again, operation repeatedly, not only add the misery of patient, also add the time of patient's anoxia
,and use also inconvenient.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, the object of the present invention is just to provide a kind of gatherer through tracheal cannula through laryngeal mask, effectively can solve the patient of tracheal intubation difficulty, when laryngeal mask cannot retain use for a long time, sets up the problem of artificial airway.
The technical scheme that the present invention solves is, the left end (also known as the inner) of seal wire is equipped with the first air bag, first air bag leads to through the second airbags of air flue and seal wire right-hand member (also known as outer end), second air bag is connected with the valve nozzle on seal wire right part, first air bag has 3 at least, be distributed on seal wire three sidewalls along seal wire circumference, each first air bag is interconnected through connection tube.
When the present invention is used in laryngeal mask and tracheal intubation transition, the comparatively branchofiberoscope that operates is simpler, easy to learn, save time, especially for the patient of tracheal intubation difficulty, transition period, the design of air bag makes air flue remain open, and the external diameter of seal wire allows to insert smoothly compared with the tracheal intubation of ting model.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention.
Fig. 2 is structure top view of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Provided by Fig. 1-Fig. 2, structure of the present invention is, the first air bag 1 left end of seal wire 2 is equipped with, first air bag is connected with the second air bag 5 of seal wire right-hand member through air flue 4, second air bag is connected with the valve nozzle 3 on seal wire right part, first air bag 1 has 3 at least, and be distributed on seal wire three sidewalls along seal wire circumference, each first air bag is interconnected through connection tube 6.
Described seal wire 2 is real core body, and left end is curved tilting upwards; Conically, conical cone point is circular arc to described seal wire 2 left end head; The second described air bag 5 is oval, be placed in seal wire, and the sidewall of seal wire is stretched out in one end; The cross section of the Breadth Maximum after the second described air bag 5 inflation is less than the cross section of seal wire; The cross section of described seal wire 2 is oval; Described valve nozzle 3 is and seal wire air inlet integrally, air inlet has sealing-plug or valve nozzle 3 are identical with the structure of bicycle valve core, have pointed article just can communicate with the external world as syringe withstands; Described seal wire 2 there is scale 7; The length of described gatherer is greater than 40 centimetres.
As can be seen from said structure, the present invention first air bag is connected with the inner of seal wire, and communicated by the valve nozzle of air flue with the second air bag, air flue is attached on seal wire, and the valve nozzle of the second air bag is attached to (valve nozzle of the second air bag can be used as the extension of seal wire outer end) on seal wire outer end.
When the present invention uses, first exhaust patient oral cavity endocrine, cruelly leaks the visual field, connect valve nozzle with syringe, take out the gas in most first air bag, by the present invention with after paraffin oil ball lubrication, hold seal wire to insert along laryngeal mask passage, the degree of depth is determined by the tracheal intubation length that will insert.After being inserted to (seal wire first air bag cross tracheal intubation the inner after), in the first air bag, fill appropriate gas.Gently outward tractive determine fixing after.Laryngeal mask is extracted.Tracheal intubation is enclosed within outside seal wire, takes advantage of a situation fixing after inserting air flue.Again take out gas in most first air bag, the present invention is extracted the foundation that can complete artificial airway.
The present invention's cost compared with branchofiberoscope is low, reduces the financial burden of patient, easy to use, easy to operate, as long as the doctor that can carry out tracheal intubation can both use, and save time, alleviate the misery of patient, be particularly applicable to the patient of tracheal intubation difficulty.
