Background technique
Blocking bronchial cannula is a kind of by the atrophy of side lung, to provide a good visual field to surgical operation.
The basic principle is that will live to block outside lung's side tracheae using the enclosure is blocked, then using will across the snorkel for blocking the enclosure
Pulmonary gases are sucked out, and are blocking snorkel with plug, so that lung side be kept to enter without gas, keep atrophy shape body.But
The existing plug for blocking bronchial cannula is single plug, to be easy to appear gas leak phenomenon, causes lung's atrophing state difficult
To keep.In addition, not supporting after existing closure bronchial cannula insertion throat, it is easy to appear shaking, so as to cause closure
Gas hood shakes, and causes to block failure.
Utility model content
To solve the above problems, the utility model discloses a kind of novel closure bronchial cannulas.The utility model structure
Simply, easy to use, it ensure that the leakproofness and stability of trachea cannula.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of novel closure bronchial cannula is intubated ontology, and the intubation body bottom portion end periphery has wrapped master
The enclosure is blocked, primary seal blocks up the enclosure and is communicated with air delivery device by gas-guide tube；Intubation bodies top is covered with sealing cover, blocks seal wire
Plug is connected with across sealing cover；Intubation body upper part side is communicated with breath return circuit joint；The intubation ontology middle inside
Convex is formed with first annular closure protrusion, and first annular closure convex top is formed with the first plugging surface；First annular closure
Raised lower part convex is formed with the second annular and blocks protrusion, and the second annular blocks convex top and is formed with the second plugging surface；It is described
Plug includes the first plug, and the first plug bottom has the first capping with the cooperation of the first plugging surface；First plug bottom connects
It is connected to vertical bar, cavity is formed with inside vertical bar, adjusting rod is placed in cavity, adjusting rod top bump forms bulge loop, cavity bottom
Portion's convex is formed with the shoulder block with bulge loop cooperation；Adjusting rod bottom is connected with the second plug, and the second plug bottom has and the
Second capping of two plugging surfaces cooperation.
Further to improve, the air delivery device is gas cell.
Further to improve, first plugging surface and the second plugging surface are arc.
Further to improve, the gas-guide tube is communicated with barometer.
Further to improve, described this body side surface of intubation is equipped with side plugging hood.
Further to improve, the plug is made of rubber.
Further to improve, the intubation body bottom portion is communicated with tracheal catheter.
Further to improve, the tracheal catheter is taper.
Further to improve, the intubation body peripheral is fixed with baffle ring, and baffle ring is set with the elastic mouth support of U-shaped.
Further to improve, the elasticity mouth support side is formed with inclination breach.
The advantages of the utility model are as follows:
1. be provided with double stopper structures, the sealing performance after ensure that intubation ontology sealing, greatly reduce gas leakage can
Energy.
2. being provided with elastic mouth support, it is therefore prevented that be intubated the shaking of ontology, ensure that the leakproofness of the stifled enclosure, and air pressure is arranged
Meter ensure that the air pressure and blow-up of the stifled enclosure, guarantee the reliability blocked.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of plug；
Fig. 3 is the side structure schematic diagram of elastic mouth support.
Specific embodiment
The utility model is described further with reference to the accompanying drawings and embodiments.
Embodiment
A kind of novel closure bronchial cannula as shown in Figs. 1-3 is intubated ontology 1, outside 1 bottom end of intubation ontology
It has wrapped primary seal week and has blocked up the enclosure 2, primary seal blocks up the enclosure 2 and is communicated with air delivery device 4 by gas-guide tube 3；It is intubated 1 main header casing of ontology
Equipped with sealing cover 5, seal wire 6 is blocked across sealing cover 5 and is connected with plug 7；Intubation 1 upper side of ontology is communicated with breathing circuit
Connector 8；The 1 middle inside convex of intubation ontology is formed with first annular closure protrusion 9, first annular 9 top of closure protrusion
It is formed with the first plugging surface 10；The raised 9 lower part convexes of first annular closure are formed with the second annular and block protrusion 11, the second annular
Closure protrusion 11 is top formed the second plugging surface 20；The plug 7 includes the first plug 12,12 bottom of the first plug
There is the first capping 13 with the cooperation of the first plugging surface 10；First plug, 12 bottom is connected with vertical bar 14, is formed with inside vertical bar 14
Cavity 15 is placed with adjusting rod 16 in cavity 15, and 16 top bump of adjusting rod forms bulge loop 17, and 15 bottom convex of cavity is formed with
The shoulder block 18 cooperated with bulge loop 17；16 bottom of adjusting rod is connected with the second plug 19, and 19 bottom of the second plug has and second
The second capping 21 that plugging surface 20 cooperates.
Air delivery device 4 is gas cell.First plugging surface 10 and the second plugging surface 20 are arc.Gas-guide tube 3 is communicated with gas
Pressure meter 22.Intubation 1 side of ontology is equipped with side plugging hood 23.Plug 7 is made of rubber.Intubation 1 bottom of ontology is communicated with gas
Pipe conduit 24.Tracheal catheter 24 is taper.Intubation 1 periphery of ontology is fixed with baffle ring 25, and baffle ring 25 is set with the elastic mouth support of U-shaped
26.Elastic 26 side of mouth support is formed with inclination breach 27.
When the utility model is used, intubation ontology 1 is inserted into lung, then primary seal is blocked up 2 He of the enclosure by the inflation of air delivery device 4
Side plugging hood 23 is inflated, and the main tracheae in lower part and side bronchus are blocked, and then breath return circuit joint 8 is connected to ventilator and inhales
Gas washes out lung's side gas, is then blocked by blocking the decentralization plug 7 of seal wire 6 by ontology 1 is intubated, has prevented extraneous gas
Body enters the lung side blocked.Since plug is double stopper structures, and it is provided with the adjustment structure that cavity 15 is formed, so that two
A plug will not interfere, so that the intubation ontology 1 for being greatly reduces gas leakage appearance by two sealing structure sealings
It may.By being arranged elastic mouth support 26 outside intubation ontology 1, so that after patient contains elastic mouth support 26, oral cavity and intubation ontology 1
Between have support, thus prevent intubation ontology 1 shaking.
