Description
Technical field
The utility model is related to medical instruments field, more precisely a kind of to be inserted with the tracheae that fiber guides are intubated
Pipe.
Background technology
The trachea cannula that traditional optical wand or light index are led causes its brightness, song often due to the defect on structure and material
Degree is dissatisfied or not accurate enough and may have situations such as fire damage, bulb come off, for neck it is excessively fat, have scar or upper breathing
If the road lesion such as patients such as tumour, wound should not apply, it is necessary to dark environment then effect is preferable.More importantly traditional gas
Cannula, after insertion tracheae, guiding article such as optical wand etc. is exited, and tends not to be accurately positioned catheter position again from body surface, such as
Due to swallowing, the reason such as restless causes catheter position movement or even de- pipe to patient, then is probably the adverse events of threat to life.Mesh
Before have no simple, convenient and rapid inspection catheter position method, generally take：Intubation scale and the method compared at 1 observation front tooth, but
The method is often inaccurate, may be bent due to pipeline etc. and to cause scale to be moved without significant change but catheter position, thereby increases and it is possible to
By influence observations such as the fixed adhesive plasters of intubation.2 row X-ray inspections are positioned, but the method (1) needs the time to wait, and may indulge in
Disease development is missed, the X-ray opaque position line of (2) trachea cannula is one, longitudinal lines along tube wall, often with cardiothoracic surgery art
Needing longitudinal X-ray above the mediastinum drainage tube placed to position caused by conventional or other situations afterwards, lines are overlapping to be obscured, two kinds of pipelines
Be all that longitudinal position line is difficult to differentiate sometimes on x-ray chest radiograph, cause that two kinds of conduit positions deviate and medical personnel are more difficult
Identification identification, in some instances it may even be possible to trigger the de- pipe of trachea cannula or drainage tube, serious not into too deep one-lung ventilation side atelectasis etc.

Brief description of the drawings
The utility model is described in detail with reference to embodiment and accompanying drawing, wherein：
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is expanded on further below in conjunction with the accompanying drawings：
As shown in figure 1, trachea cannula is inserted and can positioned to a kind of fiber guides, including fiber guides part and tracheae are inserted
Pipe, and the fiber guides part includes optical fiber 21, plastic cap 22, the dop 23 of band fixing screw, the and of LED light source generator 24
Low-voltage adapter 25, the optical fiber 21 connects a LED light source generator 24, and the LED light source generator 24 connection one is low
Voltage adapter 25.The LED light source generator 24 is provided with the dop 23 of a band fixing screw, and the optical fiber 21 is not required to when flat
When lighting, top puts plastic cap 22 and protected, it is necessary to remove plastic cap when luminous and be inserted in the card of the band fixing screw
In first 23, be tightened screw, fixed optical fiber, switches on power and light source generator can light on demand.
Trachea cannula includes intubation pipeline 11, cuff 12, X-ray opaque tag line 13, airway tube 14, instruction sacculus 15 and list
To valve 16, the tapered low pressure cuff 12 of large volume is located at the pipeline lower end of intubation pipeline 11, and wrapping 11 is peripheral one week, with 11 not
Connect, and the airway tube 14 is connected with the cuff 12, the airway tube 14 is connected with the instruction sacculus 15, and the finger
Show that the other end of sacculus 15 is provided with the check valve 16.The cuff 12 is provided with horizontal X-ray opaque tag line 13.Optical fiber 21 1
Midline on the inside of the wall of cuff 12 is fixed at end, then goes out cuff to external direction along intubation pipeline 11, there is modeling the periphery of optical fiber 21
Material membrane material parcel is combined with the pipeline of airway tube 14 before outlet plenum, and also there is plastic foil material parcel the two periphery, and attached
Outer wall traveling is responsible in intubation 11, different pipelines are divided into after outlet plenum.
Trachea cannula of the present utility model is made up of medical macromolecular materials, including intubation pipeline, cuff, airway tube, refers to
Show sacculus and check valve, joint, multifunctional rotary adapter.Cuff is the tapered low pressure cuff of high power capacity large volume.On trachea cannula
Scale is identified with cm, is represented from a distance from patient end.Mark and extremely may be used more than throat always in the incremental forms of 2-4cm after air bag
Depending on.Trachea cannula closure cuff is designed as thickening type, to avoid in catheterization procedure being scratched by tooth etc.；It is vertical with tube wall in cuff
Cross on centre of sphere greatest circle contour, X-ray opaque mark line is suppressed in cuff, cuff vertical with the longitudinal mark line of tube wall
After inflation on X rabats visible cuff centre of sphere plane largest circumference traversal marker line, can accurately show positioned at endotracheal position
Put, and will not mutually obscure with longitudinal X-ray opaque mark line of other pipelines.A superbright entire body optical fiber is inserted, is a kind of transparent
Polyacetylene compound and fluoroplastics composition software optical material, pliability well easily it is moulding, itself it is transparent light do not generate heat it is waterproof,
Just leaded light is shinny after external photophore and does not generate heat still, and brightness is higher and more increases as photophore power increases, and does not have
Fire damage, and non-laser electric wave.Fibre diameter is designed with trachea cannula model, can 1.5-5.0mm, one is inserted set
Capsule madial wall is crossed in the largest circumference of the centre of sphere a bit, and this point is located at the tube wall front institute of trachea cannula lesser curvature side to position, and solid
Due on cyst wall, then to above going out capsule and being gone with companion on the outside of airway tube, cannula body tube wall, there is one layer to add outside optical fiber and airway tube
