Description
Technical Field
The utility model belongs to the technical field of trachea cannula, and particularly relates to a trachea cannula capable of sensing concentration of end-tidal carbon dioxide.
Background
The conventional intubation mainly adopts the oral or nasal cavity photopic intubation method, namely, a laryngoscope or a fiber bronchoscope is used for judging the position of the catheter, and the fact that the catheter enters the trachea through the glottis is confirmed, which is the clinical 'gold standard'. In most cases, the general trained anesthesiologist can successfully carry out and complete the tracheal intubation. However, in the practical clinical work, when the patient suffers from head, neck and trachea diseases or has high risk factors including neck radiotherapy history, snoring, mandible retraction and other difficult trachea intubation, the glottis exposure of the patient is poor, the trachea intubation is difficult or fails, and the life safety of the patient is seriously threatened. With the development of visualization technology, visual laryngoscopes and fiber bronchoscopes are commonly used for treating difficult airways. However, the visual intubation tool still has obvious application limitation due to the influence of various conditions such as tissue swelling, secretion, bleeding and the like on the visual field. In addition, when severe environments such as hospital outside and field operations occur, the accessibility of the medical visual tool cannot be ensured due to limited conditions, and the emergency rescue takes seconds, so that a trachea cannula device is urgently needed, the concentration of carbon dioxide at the end of expiration can be sensed, whether trachea cannula succeeds or not can be rapidly judged, time is won for rescuing patients, and the success rate of treatment is improved.
The prior trachea cannula has the following problems when in use:
1. the concentration of carbon dioxide is inconvenient to judge, and whether the tracheal intubation succeeds or not can not be judged quickly;
2. when the sputum of a patient is cleaned, the ventilation must be stopped, great inconvenience is brought to the operation requiring suction for many times, and the sputum suction pipe is blocked when in use.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a trachea cannula capable of sensing the concentration of end-tidal carbon dioxide, which can conveniently judge the concentration of the carbon dioxide and is convenient for cleaning sputum in the trachea cannula.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a trachea cannula that can respond to end-expiratory carbon dioxide concentration, includes the main trachea, and the front portion of main trachea is equipped with the gasbag, and the other gasbag that connects with the gasbag intercommunication in the rear portion of main trachea fills the gassing takeover, and the rear end of main trachea is equipped with carbon dioxide and detects the coating, still other connects one on the main trachea and inhales the phlegm pipe, inhales phlegm pipe and main trachea intercommunication, is located to set up on the main trachea at phlegm pipe rear portion and inhales the phlegm pipe and puts into the hole, sets up oblique opening on the main trachea at gasbag rear portion.
Further, the carbon dioxide detection coating is arranged inside the rear end of the main air pipe.
Furthermore, a one-way membrane is arranged on the inner wall of the main air pipe at the position where the sputum suction pipe insertion hole is formed in the main air pipe, and one side edge of the one-way membrane is connected with the inner wall of the main air pipe.
Compared with the prior art, the utility model has the beneficial effects that: the main trachea is inserted into the trachea of a patient, and the carbon dioxide concentration is detected by detecting the color change of the coating through the carbon dioxide, so that whether the trachea cannula is successful or not is quickly judged; the sputum suction catheter is externally connected with the sputum suction pipe through the sputum suction pipe insertion hole to suck sputum, the main trachea 1 is not required to be separated from the breathing machine, and the main trachea is prevented from being blocked.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. a main air pipe; 2. an air bag; 3. a carbon dioxide detection coating; 4. an air bag inflation and deflation connecting pipe; 5. a sputum suction tube; 6. an oblique opening; 7. the suction catheter is placed into the hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a technical solution: the utility model provides a trachea cannula that can respond to end-expiratory carbon dioxide concentration, includes main trachea 1, the front portion of main trachea 1 is equipped with gasbag 2, and the other gasbag that connects with gasbag 2 intercommunication of the side gasbag of main trachea 1 fills gassing takeover 4, fills gassing through the gasbag and takes over 4 and can realize the gassing of gasbag 2, and the inside of main trachea 1 rear end is equipped with carbon dioxide and detects coating 3.
Still connect one by side on the main trachea 1 and inhale phlegm pipe 5, inhale phlegm pipe 5 and main trachea 1 intercommunication, it puts into hole 7 to set up on the main trachea 1 at phlegm pipe 5 rear portion to be located to inhale to set up on the main trachea, main trachea 1 sets up and inhales and is equipped with one-way membrane on the pipe wall in the position of phlegm pipe and putting into hole 7, one-way membrane side and main trachea 1 inner wall connection, one-way membrane has elasticity, do not have under the effect of external force, one-way membrane is closely laminated with main trachea 1 inner wall, be located and set up oblique opening 6 on the main trachea 1 at 2 rear portion of gasbag, can be used to inhale phlegm and wash.
