Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of for trachea cannula branchofiberoscope
Guide device.
Background technique
Currently, in clinical anesthesia, General anesthesia ratio is higher and higher, and most of general anesthesia will use trachea cannula
Art, with medical technological growth, mouth and bottleneck throat operation are followed by being gradually increased by the ratio that other positions are performed the operation, and these patients
Postoperative scar causes the risk of tracheal intubation difficulty to be consequently increased, and seriously jeopardizes patient vitals.In this case maximally efficient
Be exactly using being intubated under branchofiberoscope, but branchofiberoscope enters patient when being closed ccavum oropharygeum, by after administration
The tongue body of closure, the root of the tongue and the anatomical structures such as pharyngeal block and calmness after due to after the gravity root of the tongue pendant cause upper port
Channel block is swallowed, causes dysventilation and the visual field unclear, intubation time can be obviously increased.
Currently, clinically generally assist support lower jaw to solve using other people, but after performing the operation for fat and mouth and throat
Patient, such method are often difficult to maintain to ventilate, it is also difficult to provide branchofiberoscope the good visual field, bring very to intubation
Big difficulty wastes valuable intubation time.In the prior art, such as the patent of Publication No. " CN206566325U " is literary
It offers, discloses a kind of guide device of trachea cannula branchofiberoscope guidance, the guidance of trachea cannula branchofiberoscope is used
Guide device include seaming, air passage, dismountable guide plate and air bag, effective ventilation can be provided in the case where patient is calm
Road can be supported, so that branchofiberoscope rapidly enters sound since it has air bag by inflation/deflation counterpart bottom structure
Observation is carried out on door and into mirror, after camera lens enters tracheae, using the technical solution of the utility model, can remove lateral plate, with
Just guide device is taken out, the tracheal catheter on branchofiberoscope will be covered rapidly along camera lens and be inserted into tracheae；There is oxygen company simultaneously
Road is taken over, certain oxygen can be maintained to supply, reduce the risk of hypoxemia in intubation time.But the utility model is using
When, due to the case where effectively cannot controlling to patient's oxygen supply, patient is be easy to cause to be short of breath, in addition, sick
More germ is typically contained in the gas of people's exhalation, and patient's exhalation gas come and the oxygen of sucking are main intratracheal mixed
It closes, is easy the gas for being absorbed into patient with germ, influences the recovery from illness of patient, some even brings other state of an illness.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of guidance for trachea cannula branchofiberoscope
Device.
The utility model is achieved by the following technical programs.
The utility model provides a kind of guide device for trachea cannula branchofiberoscope, mainly includes seaming, master

The material of the ventilation tongue is medical PVC.
The thickness of the ventilation tongue is no more than 8mm.
The utility model has the beneficial effects that: using the technical solution of the utility model, in use, first will be at air bag
Under deflation status, guide device is placed in patient's bottleneck throat, source of oxygen is connected to air intake duct, oxygen passes through air intake duct, master
Tracheae to patient's bottleneck throat, is absorbed again by patient, then by guide plate and stings the branchofiberoscope equipped with tracheal catheter
Mouth enters patient's bottleneck throat, and glottis opening is found in observation, and in this process, patient can pass through air intake duct absorption oxygen, exhalation
When gas, since exhaled gas pressure is greater than oxygen pressure, then makes tongue lid conjunction air intake duct of taking a breath, exhaled gas is discharged, and inhales
When receiving oxygen, since oxygen pressure is greater than main endotracheal air pressure, make tongue expansion of taking a breath, to facilitate as patient's oxygen supply, doctor
It after shield personnel confirm that camera lens enters glottis, then extracts and deducts money after guide plate is deflated, remove dismountable guide plate, removal manually
Seaming exits fiber bronchus, facilitates the position that medical staff quickly finds bottleneck throat anatomical structure and glottis, mitigates
Labor intensity, shortens intubation time, and in operation, and patient can absorb oxygen by main tracheae, and breathe out
The gases such as carbon dioxide are then excreted by exhaust tube, and patient's deaeration time is reduced, and exhaled gas avoids mixed with oxygen
It closes, makes patient that can be absorbed into high-quality oxygen every time, other diseases of avoiding infection improve therapeutic effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- seaming, the main tracheae of 2-, 3- air intake duct, 4- exhaust tube, 5- guide plate, 6- air bag, 7- ventilation tongue, 8- are changed
Gas spring.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figure 1, the utility model provides a kind of guide device for trachea cannula branchofiberoscope, including sting
Mouthful 1, main tracheae 2, air intake duct 3 and exhaust tube 4, seaming 1 and one end of main tracheae 2 are removably joined together, air intake duct 3 and
Exhaust tube 4 is connect with the other end of main tracheae 2 in parallel, and main 2 outer wall of tracheae is coated with guide plate 5, and air intake duct 3 and source of oxygen connect
Logical, 3 outer wall of air intake duct is coated with C-shaped air bag 6.
Using the technical solution of the utility model, in use, first by air bag it is in a deflated state under, guide device is set
Enter patient's bottleneck throat, source of oxygen is connected to air intake duct, oxygen passes through air intake duct, main tracheae again to patient's bottleneck throat, by patient
It absorbs, the branchofiberoscope equipped with tracheal catheter is then entered into patient's bottleneck throat by guide plate and seaming, observation is found
Glottis opening, in this process, patient can absorb oxygen by air intake duct, when exhaled gas, since exhaled gas pressure is big
In oxygen pressure, then make tongue lid conjunction air intake duct of taking a breath, when exhaled gas being discharged, and absorbing oxygen, since oxygen pressure is greater than
Main endotracheal air pressure makes tongue expansion of taking a breath, supplies oxygen to facilitate for patient, after medical staff confirms that camera lens enters glottis,
It extracts and deducts money after guide plate is deflated again, remove dismountable guide plate manually, removal seaming exits fiber bronchus,
The position that medical staff quickly finds bottleneck throat anatomical structure and glottis is facilitated, labor intensity is alleviated, when shortening intubation
Between, and in operation, patient can absorb oxygen by main tracheae, and the gases such as carbon dioxide breathed out then pass through expiration
Pipe excretes, and reduces patient's deaeration time, and exhaled gas is avoided with oxygen and mixed, and makes patient every time and can be absorbed into and is excellent
Matter oxygen, other diseases of avoiding infection, improves therapeutic effect.
Further, the material of seaming 1, main tracheae 2, air intake duct 3, exhaust tube 4 and guide plate 5 is medical PVC.Using
The technical solution advantageously reduces environmental pollution and the invasion of other germs, improves Case treatment condition.
Further, air bag 6 is coated on away from air intake duct 3 and main 2 junction 40mm to 50mm of tracheae.
Further, the length of main tracheae 2 is 15cm to 22cm.
Further, main 2 wall thickness of tracheae is 3mm to 8mm.Using the technical solution, be conducive to keep main tracheae itself flexible
It is larger, it avoids damaging patient's throat.
Further, 3 diameter of air intake duct is greater than 4 diameter of exhaust tube.
Further, the guide device for trachea cannula branchofiberoscope further include ventilation tongue 7 and ventilation spring 8,
