Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of selectivity light transmission tracheal catheter.
Background technique
General anesthesia needs tracheal catheter to protect air flue at present, by tracheal catheter by oral cavity or nasal cavity, is inserted into through glottis
Tracheae or bronchus, for respiratory passage unblocked, supply oxygen, secretion attraction the technology of condition is provided, after insertion also it needs to be determined that
Whether correct, most classic judgment method is to pass through auscultation with stethoscope in catheter end respiratory balloon or ventilator assisted ventilation
Double pulmonary respiration sounds judge, if tracheal catheter not inside tracheae, but is strayed into oesophagus, then breath sound cannot be heard.
But above-mentioned judgment method is judged after conduit insertion, if tracheal catheter is strayed into oesophagus and will lead to largely
Gas enters stomach, and when extraction tracheal catheter is intubated again, stomach tonic contraction is easy gastric content squeezing into oesophagus, oral cavity, and
Tracheae, lung etc. are flowed into, pneumonia, bronchial asthma, or even asphyxia are caused.
Utility model content
The purpose of this utility model is to provide a kind of selective light transmission tracheal catheters, to solve existing tracheal catheter not
The problem of being easy real-time judge catheter position.
To achieve the above object, the technical solution of the utility model is to provide a kind of selective light transmission tracheal catheter, described
Selective light transmission tracheal catheter includes opaque tube body, the connection tube for being mounted on opaque tube body upper port and is mounted on impermeable
The first air bag on bright bottom of the pipe tube wall is fixed with gas tube, the outlet of the gas tube in the middle part of the opaque tube body
End is connect with the first air bag, and is formed with one section for passing through for light on the tube wall that opaque tube body is located at gas tube side
Transparent surface.
Further, the width range of the transparent surface is 0.5mm-1.5mm.
Further, the transparent surface is located in the middle part of opaque tube body between the first air bag.
Further, the opaque tube body is equipped with close to the tube wall of connection tube and is located on same axis with transparent surface
Mark line.
Further, the second gas for detecting air pressure in the first air bag is installed on the tube wall of the gas tube inlet end
Capsule.
The utility model has the advantages that
Before the selective light transmission tracheal catheter conduit of the utility model is by only staying center on the lighttight tube body of whole body
There is a narrow slit light transmission in face, after intubation, enters conduit to emanating light source, and light is made to form one along conduit by conduit transparent surface
The light beam of trend, through organizing before person's windpipe, the trend and position convenient for clear view conduit avoid conduit insertion oesophagus from making
It is blindly detected when bulk gas enters stomach or tracheotomy and causes bleeding, damage, cause unnecessary risk.
In figure, 1, opaque tube body；2, connection tube；3, the first air bag；4, gas tube；5, transparent surface；6, mark line；7,
Two air bags.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the selective light transmission tracheal catheter of the utility model.
Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
As shown in Figure 1, the utility model provides a kind of selective light transmission tracheal catheter, including opaque tube body 1, installation
Connection tube 2 in opaque 1 upper port of tube body and the first air bag 3 for being mounted on opaque 1 lower end tube wall of tube body, wherein holding in the mouth
Adapter tube 2 is for connecting respiratory balloon or ventilator.At the middle part of opaque tube body 1 it is fixed with gas tube 4, wherein gas tube 4
Nozzle diameter is less than the nozzle diameter of opaque tube body 1, and the outlet side of gas tube 4 is connect with the first air bag 3, leans on gas tube 4
The tube body of nearly opaque tube body 1 is tightly attached on the tube wall of opaque tube body 1, the inlet end of gas tube 4 far from opaque tube body 1,
And the second air bag 7 for detecting air pressure in the first air bag 3 is installed on tube body of the gas tube 4 close to inlet end.When impermeable
When bright tube body 1 is inserted into person's windpipe, in order to make ventilator, loop circuit of respirator and the lung of patient form a closed circuit,
It is inflated by gas tube 4 into the first air bag 3, expand the first air bag 3 and closes the gap between conduit and inner surface of trachea, prevented
Only gas leakage when positive airway pressure, and avoid upper respiratory tract secretion or gastric content reflux to intratracheally causing accidentally to inhale, due to
Two air bags 7 are also connected to gas tube 4, and the expansion synchronous with the first air bag 3 of the second air bag 7, can pass through the second air bag 7 at this time when inflation
Degrees of expansion judge the air pressure in the first air bag 3, avoid the first air bag 3 from inflating and excessive destroy tracheal wall.
As noted previously, as tracheal catheter is likely to enter oesophagus in insertion process, therefore it is located in opaque tube body 1 and fills
One section of transparent surface 5 for passing through for light is also formed on the tube wall of 4 side of tracheae, specifically, transparent surface 5 is positioned at opaque
Between 1 middle part of tube body and the first air bag 3, and the width range of transparent surface 5 is 0.5mm-1.5mm.After being inserted into tracheal catheter not
With air-blowing, auscultation is not had to, after external light source irradiation makes light enter conduit, light will be by saturating on opaque tube body 1
Smooth surface 5 forms a light beam along conduit trend, if conduit organizes thickness before oesophagus, conduit, light can not be penetrated, be led
Pipe is then organized less and thin inside tracheae before conduit, light is easy to through tissue, by light through group before person's windpipe
It knits, trend and position convenient for clear view conduit, and then avoids tracheal catheter insertion oesophagus that bulk gas is caused to enter in time
Stomach causes unnecessary risk；Simultaneously when some patients need row tracheotomy, in order to protect air flue to need leading tracheae
Intubation, after intubation when light beam is pierced by from neck, just provides foundation for autogenous cutting operator, can arrive tracheae with clear view
Position avoids blindly detecting and causes the risks such as bleeding, damage.Due to opaque tube body 1 when being inserted into person's windpipe sometimes for
Rotation insertion can not observe directly the transparent surface 5 of opaque tube body 1 after being inserted into person's windpipe, it cannot be guaranteed that transparent surface 5 begins
All morning is additionally provided on the tube wall of connection tube 2 in opaque tube body 1 and is located at transparent surface 5 to organizing direction before human body
Mark line 6 on same axis judges the position at 5 place of transparent surface after the opaque insertion of tube body 1 person's windpipe by mark line 6
It sets, and is corrected, observed convenient for medical staff.
Before the selective light transmission tracheal catheter conduit of the utility model is by only staying center on the lighttight tube body of whole body
There is a narrow slit light transmission in face, after intubation, enters conduit to emanating light source, and light is made to form an edge by the transparent surface 5 of conduit
The light beam of conduit trend, through organizing before person's windpipe, the trend and position convenient for clear view conduit avoid conduit insertion food
Pipe makes bulk gas enter stomach, causes unnecessary risk.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
