Description
Technical field
Medical instrument field of the present invention more particularly to a kind of tracheal catheter with automatic eliminating the phlegm function and automatic eliminating the phlegm dress
It sets.
Background technique
Trachea cannula refers to the technology by a special endotracheal tube through glottis merging tracheae, this technology of trachea cannula
It can help to realize that airway patency, ventilation oxygen-supplying, respiratory tract attract and prevent from accidentally inhaling.
If merging generally cannot take off pipe in 3-7 days or so patients to tracheal catheter for a long time, it is necessary to tracheotomy is carried out,
Tracheotomy is not only costly, and risk is big, is also easy to cause infection of incisional wound after tracheotomy, or even cause the death of patient.I.e.
Make tracheotomy rehabilitation, be also frequently accompanied by the significant scar of patient's neck, not only influence appearance, it is narrow to also result in tracheae lacuna, band
Carry out other risks.Inhaling-conveying mode generallys use the 2-3 hours artificial suction sputums in interval during trachea cannula at present.Interim sputum exists
Intratracheally gather, in breathing, fluxion strap walks moisture to air-flow back and forth, causes sputum drying in part to form phlegm scab, it is difficult to which negative pressure is inhaled
Out or even phlegm scab blocks tracheal catheter inner cavity, and aeration resistance increases, and airway pressure increases.Meanwhile artificial suction sputum also increases medical care people
The burden of member, multiple suction sputum operation can cause to damage to tracheal mucosa, lead to tunica mucosa tracheae cilia damage, and expectoration ability declines,
Increase patient lungs and infects probability.
Therefore, it is urgent to provide a kind of low damage, high efficiency, can eliminating the phlegm automatically tracheal catheter and automatic eliminating the phlegm device,
It reduces patient lungs and infects probability, extend the duration of ventilation of tracheal catheter merging, reduce tracheotomy probability.
Summary of the invention
The embodiment of the invention discloses a kind of tracheal catheter with automatic eliminating the phlegm function and automatic eliminating the phlegm devices, using logical
Real-time suction sputum is crossed, so that tracheal catheter is overstock without sputum, to extend the wear time of tracheal catheter, gives patient's foot
Enough rehabilitation durations avoid carrying out bronchotomu.
To achieve the goals above, the embodiment of the invention provides a kind of tracheal catheter with automatic eliminating the phlegm function, packets
It is placed in endotracheal shared snorkel when including ventilation, is located at extratracheal air intake duct and exhaust tube, the shared snorkel difference
