Description
Technical field
The utility model is related to technical field of medical instruments, specifically, is a kind of novel ultrasonic atomization sputum aspirator.
Background technology
Suction sputum is a conventional technology that respiratory smooth is kept when giving emergency treatment to a patient, and respiratory secretions is suctioned out, with
Keep respiratory passage unblocked, prevention aspiration pneumonia, expiratory dyspnea, or even asphyxia.Suitable for being after critical, old, stupor, anesthesia
Clear-headed person, causing can not be by sputum expectoration.
Commonly used in the prior art is that sputum aspirator is a straight sputum aspirator tube, external connecting negative pressure device composition.Inhaled when using
At phlegm pipe insertion person's windpipe position, then suction sputum is carried out using negative pressure.However, having the following disadvantages and lacking in actual use
Fall into.
First, sputum aspirator tube of the prior art is straight sputum aspirator tube, does not meet human dissection physiological structure, person's windpipe exists
Distribution is reverse Y-shaped below throat, its straight sputum aspirator tube easily contradicts the meet in two tracheaes when inserting, and causes suction sputum to be lost
Lose.The diameter and shape of straight sputum aspirator tube are fixed, in order to fully suction out sputum, the chi of its straight sputum aspirator tube
Very little design is designed according to tracheae size, and inner surface of trachea mucous membrane is easily damaged when in use.
Secondly, the airflow direction of the vacuum suction of sputum aspirator of the prior art is unidirectional, its one-way gas flow suction sputum
Effect is insufficient, is mixed because sputum contains many kinds of substance, in tacky state, has adhesion strength to respiratory tract inwall, right
In the sputum that adhesion strength is larger, sputum can not then be suctioned out by unidirectional airstream suction.
In addition, sputum aspirator of the prior art is only that can attract the sputum in front of sputum aspirator tube, and for positioned at suction
Sputum on the wall of phlegm pipe side, then can not suction out, moreover, suction sputum is a dynamic process in itself, even the phlegm in front of sputum aspirator tube
Liquid, because under suction function, on the direction for being moved to sputum aspirator tube side wall so that sputum can not be suctioned out, adding the difficulty of suction sputum.
Furthermore, sputum aspirator, is not diluted the operation of atomization to sputum in the prior art, easily causes blocking, plus
There is temperature difference, cause the miopragia of " fibre swing " on inner surface of trachea, easily cause tracheospasm and atelectasis etc.
Complication.
In summary, there is adverse consequences, such as tunica mucosa tracheae damage, atelectasis, branch gas during suction sputum in existing equipment
Pipe spasm, hypoxemia, infection, artificial airway's blocking and suction sputum blockage etc..Need badly one kind can reduce damage tunica mucosa tracheae,
Can plastotype, can carry out different airflow direction suction sputums, can by ultrasound be atomized and humidifying handle novel ultrasonic atomization suction
Sputum device.And yet there are no report on this novel ultrasonic atomization sputum aspirator.
The content of the invention
The purpose of this utility model be for it is of the prior art it is not enough there is provided one kind reduce damage tunica mucosa tracheae, can
