Description
Technical field
The utility model relates to a kind of tracheal catheters for preventing one-lung ventilation, belong to the field of medical instrument technology.
Background technique
Tracheal catheter intubation technique is developed so far existing more than 100 year, is that anesthetic intubate and Cavity in Critical Patients rescue are common
A kind of clinical emergency treatment technical ability；With the progress of industrial development, the material and technology for making conduit increasingly meet clinical requirement, but
It is that tracheal catheter is used in clinical process that there are still deficiencies, for example is intubated too deep One-lung ventilation and tracheal catheter distal end phlegm
Scab problem etc., it is not only related to material, it is more designed with its structure closely related.
Currently, clinically most-often used tracheal catheter is monosaccate and right unilateral hole, since Cavity in Critical Patients needs
Artificial airway is established for a long time, and tracheal catheter distal end easily phlegm scab is formed after intubation ventilation for a long time, is influenced after luminal stenosis logical
Gas；Since right side bronchus is relatively steep, tracheal catheter was slided to intrapulmonary after clinical often appearance is intubated too deep or improper operation
It is deep, right side one-lung ventilation is caused after left principal bronchus blocking, eventually leads to hypoventilation, infection control is unsatisfied etc., seriously
Affect intubation prognosis.Therefore the using effect of existing tracheal catheter or not ideal enough, is not able to satisfy use
Needs.
Utility model content
The purpose of the utility model is to provide a kind of structures to be simple and convenient to operate, safe to use and can increase
Tracheae expectoration effect, the tracheal catheter for preventing one-lung ventilation for promoting expectoration and effectively reducing the incrustation of trachea cannula distal end sputum,
To overcome the deficiencies in the prior art.
A kind of tracheal catheter preventing one-lung ventilation of the utility model, including catheter body, the upper end of catheter body be equipped with
The interface that Anesthesia machine or ventilator are connected is equipped with blow vent in the lower end of catheter body, in catheter body at vent locations
Side pipe is equipped at least two side blow vent, is equipped with conduit insertion section air bag by the top of nearside vent locations on catheter body,
It is communicated after the inner tube that one end of conduit insertion section air bag inflating catheter passes through catheter body with the inner cavity of conduit insertion section air bag, conduit
The other end of insertion section air bag inflating catheter is located at the outside of catheter body and fills exhaust air-bag with conduit insertion section air bag and connect；?
It is equipped with the outer air bag of glottis close to the top of conduit insertion section air bag on catheter body, one end of the outer air bag inflation ductule of glottis passes through
It is communicated after the inner tube of catheter body with the inner cavity of air bag outside glottis, the other end of the outer air bag inflation ductule of glottis is located at catheter body
Outside is simultaneously filled exhaust air-bag with air bag outside glottis and is connect.
Air bag is all wrapped on catheter body above-mentioned conduit insertion section air bag harmony outdoors.
2~6 side blow vents are equipped on the side pipe at vent locations in above-mentioned catheter body.
The shape of above-mentioned side blow vent is circular through hole or long stripes through hole.
By adopting the above-described technical solution, traditional tracheal catheter is improved to single tube double bolloon tracheae by the utility model
Guide-tube structure, the tracheal catheter for preventing one-lung ventilation of the utility model include oral cavity exposed parts, buccal portion and intratracheal
Plug part；Interpolation portion distal end of catheter is successively arranged blow vent, multiple side blow vents, conduit insertion section air bag；Buccal portion packet
Include the outer air bag of glottis and oral cavity inner catheter position, exposed parts there are two fill exhaust air-bag by inflation small pipeline respectively with lead
It pipe insertion section air bag and is communicated with air bag outside glottis, the interface with silica gel sealing ring is equipped at the port of exposed parts.This
Utility model interpolating unit distal end in tracheal catheter sets multiple side blow vents, efficiently reduces conduit to the compressing area of tracheae, together
When increase tracheae expectoration effect, promote expectoration, and effectively reduce trachea cannula distal end sputum incrustation；The utility model it is interior
Multiple side blow vents of interpolating unit, can not only effectively increase ventilatory function, caused by can also effectivelying prevent tracheal tube insertion too deep
One-lung ventilation；It can reinforce prevention tracheal tube after the outer air bag inflation of the glottis in its oral cavity portion to slide into too deep and accident occurs.Institute
Compared with prior art with, the utility model, the utility model not only have it is safe to use, can increase tracheae expectoration effect
The advantages of with promoting expectoration and reducing the incrustation of trachea cannula distal end sputum, but also be simple in structure and convenient in use.
