Description
Technical field
The utility model relates to a kind of intratracheal operation high-frequency ventilation gas operated devices.
Background technique
A variety of diseases and iatrogenic factors can cause air flue benign stricture, and the country is mostly with trachea and bronchus tuberculosis, gas
Pipe is cut oppresses based on caused tracheostenosis for a long time with cuff for endotracheal catheter after tracheae branch pipe.It is guided in branchofiberoscope
Under, high pressure balloon expandable air flue plasty is carried out to narrow air flue, it has also become the effective ways for the treatment of air flue benign stricture it
One.Using laryngeal mask airway under general anesthesia, both mitigate patient suffering；Relatively stable circulation is maintained again, while can maintain higher suction
Enter oxygen concentration, and can be operated for branchofiberoscope and a preferable visual field and surgical procedure region are provided.However, for
The patient of airway constriction, since secretion and bleeding block air flue, while the operation of branchofiberoscope, GENERAL ANESTHETICS is to independently exhaling
The inhibiting effect of suction, patient are easy to happen the danger of asphyxia, and the positive airway pressure above narrow tracheae is usually ineffective.Pass through
High-frequency ventilation gas operated device protrudes into the lower section of narrow tracheae, connects high frequency jet ventilator and carries out high-frequency jet ventilation, it may be possible to this
More satisfactory ventilating mode in the case of kind.In addition, in the course of surgery high pressure balloon expandable air flue when, it is sometimes necessary to repeatedly
Of short duration pause Anesthesia machine ventilation, but at this moment this high-frequency ventilation gas operated device can continue to keep ventilation, therefore extend ball
The time of capsule expansion.
Severe pneumonia is the common critical illness of paediatrics, is children's especially infant period major causes of death.Bronchofiberscope
Because it has unique advantage in terms of diagnosing and assessing pulmonary lesion, and can flexibly be handled for situation in art,
Alleviate the critical situation such as infant airway obstruction in time by measures such as bronchoalveolar lavages (BAL), improves infant work of breathing
Can, strive for the time for the rescue of critical diseased children.However, infant is in laryngeal mask airway anesthesia downlink bronchoalveolar lavage, it can also
The complication such as pulmonary edema and anoxic can occur.When bronchoalveolar lavage, it is fast that the positive airway pressure of ventilator may cause irrigating solution
Speed enters the bronchiole in deep and alveolar leads to not be attracted, to induce pulmonary edema；If the breathing of ventilator pause at this time,
Since infant oxygen reserve is poor, it is easy to appear anoxic.At this point, being filled in non-lavation side lung (i.e. strong side lung) row by high-frequency ventilation air guide
It sets progress high-frequency jet ventilation and is undoubtedly comparatively ideal ventilating mode.But clinically have no that this suitable high frequency jet is logical at present
The gas operated device of gas.
Foreign body in airpassage is one of most common ear-nose-throat department acute disease, can there is expiratory dyspnea, asphyxia, pulmonary emphysema, atelectasis etc.
Complication is mainly in infant, and the life security of infant is threatened when serious, is especially fallen off in the foreign matter in bronchus deep, branch gas
It manages hard mirror to be not easily taken out, can only be taken out using branchofiberoscope, laryngeal mask airway anesthesia can both be operated for branchofiberoscope and be provided
One preferable visual field and surgical procedure region, and respiratory tract can be preferably controlled, become current children's branchofiberoscope
The preferred anesthesia method of lower tracheae or foreign body in bronchus removal surgery.However, either retaining autonomous respiration still under laryngeal mask airway anesthesia
Positive airway pressure, the flowing of gas may all influence the taking-up of foreign matter, at this point, can both protect in strong side lung row high-frequency jet ventilation
Certain gas exchanges are held, and do not influence branchofiberoscope in the operation of foreign matter laterobronchus, undoubtedly comparatively ideal ventilation
Mode.But there is not the gas operated device of this suitable high-frequency jet ventilation clinically at present.
