Description
Technical field
The utility model relates to a kind of medical suction, dilution, flushing or device for drawing-in and pumping-out, in particular to a kind of two-chamber tracheaes to insert
Pipe.
Background technique
Lung Sequestration is common respiratory nursing technology in surgical operation anesthesia, specifically will using Dual-channel tracheal cannula
The bronchial airways of left and right side lung are isolated, and realize selective one-lung ventilation.Purpose is while providing effective ventilation, to strong
Side lung carries out implementing to implement related surgical to Ipsilateral lung while air flue protection, and can prevent the blood of Ipsilateral lung, secretion and
Cancerous issue etc. enters the generation that strong side causes the adverse events such as infection, diffusion and respiratory tract obst ruction.In addition, one-lung ventilation can
Make the art side collapse of lung, so that good visual area is created, conducive to searching extent of disease and mitigating the damage of non-ablated part lung.Mesh
Before, with the extensive development of thoracoscopic surgery techniques, bronchial alveolar lavage art and thoracic aortic surgery, the application of lung Sequestration is increasingly general
And.
But deep due to being inserted into after application dual-lumen cannula, can be generated by being responsible on cuff and bronchial cuff by many points
Secretion；If these secretion in time, cannot be cleared up effectively, pulmonary infection, cough of choking, tracheae or bronchial obstruction can be caused
Property accident；Traditional dual-lumen cannula can not solve the problems, such as above-mentioned clinical puzzlement.
Summary of the invention
The utility model provides a kind of suction type Dual-channel tracheal cannula, and purpose makes it be provided simultaneously with suction, dilution, rinse function
Can, more convenient in clinic, easy for operation, the Probability of reduction related infection and accident mitigates patient
Financial burden.
The technical scheme adopted by the utility model is that: including main body vented cannula, which is double lumen tube,
There is bronchial airways pipeline in inside, and supervisor's cuff, charge valve and the filling channel one being connected in main body vented cannula are connected to
Bronchial cuff, charge valve and venting channels two on the bronchus head end of bronchial airways pipeline；Above supervisor's cuff, master
There are the dedicated pump orifice one of sequential connection, suction, flushing and dilution tunnel one on the tube wall of body vented cannula, suction is rinsed
With dilution tube one, negative port one；There is the dedicated suction of sequential connection on the top of bronchial cuff, bronchus head end tube wall
Mouth two, suction, flushing and dilution tunnel two, suction, flushing and dilution tube two, negative port two.
There is ventilation side opening on the bronchus head end tube wall.
The ventilation side opening shape is round, oval, diamond shape or rectangle.
The ventilation side opening quantity is 1~3.
The negative port one side is connected to the suction mouth one with nut cap.
The negative port two side faces are connected to the rinse mouth two with nut cap.
The utility model has the advantages that: structure novel has suction, dilution, suction three zones, can in time, effectively
Removing sound is responsible for the secretion on cuff and bronchial cuff, can ensure being normally carried out, can avoid associated lung for surgical work
The generation of infection, the secondary injury that can avoid patient airway, the financial burden that also can reduce patient；The utility model is more convenient
Clinical use reduces the generation of clinical some potential complication, has ensured going on smoothly for ventilation means；Make to be intubated simultaneously
Adverse reaction reduction after extraction；It ensures that patient lungs effectively ventilate, avoids anoxic；Airway management can be safely and effectively carried out,
Ensure that patient is a kind of clinical prods widely used, easy to use in the safety for enclosing the respiratory nursing phase.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Specific embodiment
Including main body vented cannula 1, which is double lumen tube, inside have bronchial airways pipeline 18, even
Supervisor's cuff 3, charge valve and filling channel 1 in main body vented cannula 1 are connect, the branch of bronchial airways pipeline 18 is connected to
Bronchial cuff 11, charge valve and venting channels 29 on tracheae head end 10；Above supervisor's cuff 3, main body vented cannula 1
Tube wall on have a dedicated pump orifice 1 of being linked in sequence, suction is rinsed and dilution tunnel 1, and suction is rinsed and dilution tube one
6, negative port 1；There is the dedicated pump orifice two that is linked in sequence on the top of bronchial cuff 11,10 tube wall of bronchus head end
12, suction, flushing and dilution tunnel 2 13, suction, flushing and dilution tube 2 14, negative port 2 15；
There is ventilation side opening 17 on the bronchus head end tube wall；
The ventilation side opening shape is round, oval, diamond shape or rectangle；
The ventilation side opening quantity is 1~3；
One 7 side of negative port is connected to the suction mouth 1 with nut cap；
2 15 side of negative port is connected to the rinse mouth 2 16 with nut cap.
The rinse mouth one, two of the nut cap is standard interface, can be matched with apparatus such as syringes, and has nut cap,
Nut cap is kept to cover when not in use.
The bronchial lumen pipe end of the described ventilation side opening for having shape indefinite is micro-bend design, can make conduit be easy into
Enter lung's main bronchus；Two lumen head end openings are both designed as diagonal cut joint simultaneously, more conducively guarantee ventilatory capacity, evade anoxic thing
The generation of part；Furthermore in order to avoid implementing to cause to damage to airway mucus in catheterization procedure, head end can be subjected to sofening treatment, together
When head end opening be designed as smooth inclined-plane, edges and corners carry out smooth surface processing.
Working principle: in use, cuff 3, the inflation of bronchial cuff 11 are responsible for respectively, when supervisor's cuff and bronchial cuff
On secretion when needing to clear up, can be aspirated from dedicated pump orifice 1 and pump orifice 2 12, can if secretion is too viscous
Suction mouth 1 and rinse mouth 2 16 with nut cap are opened, then is connect respectively with apparatus such as syringes, is infused by syringe etc.
Enter water to be diluted, then aspirates.
