Description

bronchoscopic laryngeal mask endotracheal tube

technical field

The utility model relates to a medical device for establishing an artificial airway channel for a patient, in particular to a laryngeal mask trachea catheter which can be inserted with a fiber bronchoscope and used for surgical anesthesia, assisted breathing or rescue of critically ill patients.

Background technique

A laryngeal mask endotracheal tube is an airway that uses extraglottic ventilation.

In the anesthesia operation using a laryngeal mask, some patients need to insert an endoscope into the patient's body for observation or auxiliary surgery. For example, sometimes it is necessary to insert a fiberoptic bronchoscope into the patient's airway and lungs for observation or auxiliary surgery. There needs to be a dedicated channel to insert the bronchoscope.

Ordinary laryngeal masks are mainly used for airway ventilation without a dedicated channel, so some patients who need endoscopic surgery cannot choose to use a laryngeal mask for surgery. In the prior art, tracheal intubation is usually used for ventilation or an incision is made to insert an endoscope to solve the above problems. The above two methods increase the pain of the patient and cause greater damage to the patient; sometimes on the basis of an ordinary laryngeal mask Add a three-way joint on the top, and intubate the endoscope while ventilating. This method also has problems. Because the endoscope and ventilation share a lumen, it will affect the continuous ventilation of the operation, and it is inconvenient to use.

Utility model content

The technical problem to be solved by the utility model is to provide a fibrobronchoscopic laryngeal mask tracheal catheter with simple structure, easy operation and no influence on continuous ventilation during operation.

The utility model bronchoscopic laryngeal mask endotracheal catheter comprises a main pipe with openings at both ends, a throat sealing bag, and an esophagus sealing bag. The main pipe is provided with an inflatable cavity, and the inflatable cavity is respectively connected with the throat sealing bag and the esophagus sealing bag. A fiberoptic bronchoscope cavity and a ventilating cavity are also arranged in the main pipe, and a cover is connected to the fiberoptic bronchoscope cavity.

The endotracheal catheter of the fiberoptic bronchoscope laryngeal mask of the utility model is provided with a blind hole at one end of the main pipe.

In the utility model, the bronchoscopic laryngeal mask endotracheal catheter, wherein the side wall of the inflatable cavity is provided with two ventilation holes, and the gas-inflating cavity communicates with the throat sealing bag and the esophagus sealing bag respectively through the two ventilation holes.

The utility model relates to a bronchoscopic laryngeal mask endotracheal catheter, wherein one end of the inflatable cavity is connected with an inflatable tube.

The difference between the bronchoscopic laryngeal mask endotracheal catheter of the utility model and the prior art lies in that the endotracheal tube of the bronchoscopic laryngeal mask of the utility model comprises a main pipe, a throat sealing bag, and an esophagus sealing bag, and the two sealing bags are used for sealing the esophagus and the throat respectively. It is sealed to establish an airway for ventilation, and the structure is simple; at the same time, there are two independent channels in the main tube, the fiberoptic bronchoscope cavity and the ventilation cavity. When the cover is closed, when it is necessary to insert a bronchoscope and other endoscopes, you only need to open the cover and insert the bronchoscope into the airway for inspection or surgery. It will affect the continuous ventilation of the operation.

One end of the main tube of the utility model fiberoptic bronchoscope laryngeal mask endotracheal tube is provided with a blind hole. The design of the blind hole can reduce the wall thickness and make the end soft, so as to reduce the stimulation of tube placement and minimize the damage to the mucous membrane.

The fiberoptic bronchoscope laryngeal mask endotracheal tube of the present utility model will be further described below in conjunction with the accompanying drawings.

detailed description

As shown in Figure 1, the bronchoscope laryngeal mask endotracheal catheter of the present invention comprises a main pipe 8 with openings at the front end and rear end, a throat sealing bag 4 for sealing, and an esophagus sealing bag 5, and an inflatable chamber 1 is arranged in the main pipe 8, The side wall of the inflatable chamber 1 is provided with two ventilation holes, and the inflatable chamber 1 communicates with the throat sealing bag 4 and the esophagus sealing bag 5 respectively through the two ventilation holes, and the main tube 8 is also provided with a fiberoptic bronchoscope cavity 2 and a ventilation chamber Road 3, the fiberoptic bronchoscope cavity 2 is connected with a cover 6, the rear ends of the inflatable cavity 1, the fiberoptic bronchoscope cavity 2, and the ventilation cavity 3 are all located at the rear end of the main pipe 8, and the rear end of the gas-filled cavity 1 is connected with Inflatable tube 9 is used to inflate throat sealing bag 4 and esophagus sealing bag 5. During use, the air in throat sealing bag and esophagus sealing bag is drained earlier by the inflation tube. Throat seal bag and esophagus seal bag are filled with a specified amount of air to bulge the throat seal bag and esophagus seal bag. It can fit well with the esophagus to form a seal, and then establish airway ventilation.

In the utility model, the front end of the main pipe 8 is provided with a blind hole 7, and the setting of the front blind hole 7 reduces the wall thickness to make the front end soft, and reduces the stimulation of tube placement and the damage to the mucous membrane.

The bronchoscope laryngeal mask tracheal catheter of the utility model includes a double-cavity structure of a ventilating cavity 3 and a bronchofiber-inserting cavity 2, and the two cavities are set independently. The utility model also has a throat sealing bag 4 and an esophagus sealing bag 5 The dual-sac sealing structure can respectively seal the esophagus and throat to establish an airway for ventilation. The design of the independent ventilation channel 3 and the fiberoptic bronchoscope cavity 2 avoids the need to share one cavity. The influence of the channel on continuous ventilation and on the demand for ventilation.

When ventilation is required, it is only necessary to cover the cavity 2 of the bronchoscope with the cover 6; when it is necessary to insert a bronchoscope or other endoscope, it is only necessary to open the cover 6 and insert the bronchoscope into the airway for inspection or surgery , Easy to operate.

The above-mentioned embodiments are only described to the preferred implementation of the utility model, and are not limited to the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the utility model.
