Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of trachea cannula that can monitor gasbag pressure automatically.
Background technology
Trachea cannula establishes the artificial airway of patient suitable for clinic, implements mechanical ventilation, surgery anesthesia or the heart to it
The use such as lung recovery.Airbag aeration size on trachea cannula and aeration quantity stability determine respiratory function support technology whether at
Work(.The leakproofness of trachea cannula and patient airway is the key that mechanical ventilation and prevents oropharynx secretions from accidentally inhaling institute
.Airbag aeration crosses conference tracheas suppressed tissue and causes ulcer or balloon rupture, under-inflation can the work of gas leakage effect lung ventilator
Or it accidentally inhales.Current most of medical staff are to touch the instruction sacculus that is connected with air bag with hand by experience when using trachea cannula
Aeration quantity it is whether damaged come the size or air bag for judging the tracheal intubation airbag aeration quantity for being orally inserted in patient's trachea position.It is complete
It is difficult entirely to avoid error in judgement by experience and feel, medical staff's feel and criterion are also different, and especially airbag aeration is not
Foot or gas leakage can not be found in time, result in Breathing Suppotion to fail in this way, cause the respiratory failure of serious patient even dead.Cause
For airbag aeration deficiency, oropharynx secretions leak into the major reason that lower respiratory tract is Ventilator-associated pneumonia, are
Global problem, clinical lethality are high.
Patient once implements trachea cannula simultaneously, and tracheal catheter indwelling time is generally：Oral trachea cannula is usually no more than
72 hours；It is no more than 1 week through nasal intubation.And some patients, cardio-pulmonary function are poor, respiratory secretions is more, when can extend indwelling
Between.Pars cervicalis tracheae incision cannula may also be taken, can be longer so as to the time of indwelling, but this operation wound is big, nurses difficulty
Greatly.Although trachea cannula solves dysventilation, facilitates the foreign matters such as the sputum blood being sucked out in air flue at the beginning, due to
The trachea cannula conduit of Clinical practice is mainly made of medical polyethylene plastics at present, and conduit has adhesiveness to airway secretions,
Compressing, friction, stimulation etc. occur for airway mucus after intubation, are very easy to cause to be intubated complication, lead to catheter retaining failure and
Have to tube drawing, terminates treatment.
