Description
Technical field
The utility model relates to medical instruments fields, and in particular to a kind of novel gas passage interventional therapy single-chamber band sacculus gas
Cannula.
Background technique
The common trachea cannula of bronchus intervention operation has double lumen endobronchial tube inner catheter (DLTs) and single lumen endobronchial tube,
Dual cavity bronchus vessel is two cavity configuration of a pipe, two sections of two openings, tracheae section of the opening positioned at conduit, another opening position
In distal end main bronchus section, although such structure meets the function of leaving Ipsilateral septum bronchiale, double lumen endobronchial tube is led
The outer diameter of pipe is thicker, and row easily damages respiratory tract when being intubated, while catheter diameter is meticulous, and bronchoscope cannot pass through two-chamber branch gas
Pipe is operated, and especially right upper lung main bronchus opening is easily by balloon occlusion.Compared to relatively descending single lumen endobronchial tube
Diameter can be made smaller, prevent intubation when lose respiratory tract.
Occurring bleeding in bronchus intervention operation causes air flue asphyxia to be the severe complication that surgical doctor is most worried, is
Preventing Ipsilateral bronchrohagia from flowing into causes the ventilation of strong laterobronchus to cause the respiratory failure that suffocates in tracheae, while needing in art
Vacuum suction is carried out to Ipsilateral bronchus, prevent that operation view is resulted in blockage or influenced in the bronchus of blood accumulation and Ipsilateral
Open country, however existing single lumen endobronchial tube needs to separate conduit with ventilator when to patients bronchial's negative pressure drainage, so
Drainage tube is inserted into from Ipsilateral bronchus from tracheal respiration interface using negative-pressure ward afterwards, this mode of operation has high
Risk, and need in this case operator complete in a very short period of time negative pressure suction sputum operation, misoperation or
It is unskilled to have serious consequences to patient；The diameter of negative-pressure suction pipe is reduced and from single-chamber branch by improved single-chamber bronchus
It is inserted into the respiration channel of tracheae and is reserved in the side of conduit and attract interface tube, although this mode, which can exempt, pulls up ventilator
Bring risk, however the suction tube in conduit cavity will cause the breathing that air exchange pipe sectional area reduces and influences patient, and
Caliber is too small will to be difficult to carry out Ipsilateral bronchus hydrops drainage operation, and drainage tube is difficult to replace, and the mucus pasted in tube body will
It will lead to the obstacle of repetition attraction and Ipsilateral ventilation.
