Background Art

With the rapid growth of my country's economy and the rapid development of social modernization, people pay more and more attention to the health of the body, especially the digestive tract. Upper gastrointestinal endoscopy and treatment play a major role in the diagnosis and treatment of upper gastrointestinal diseases. Among them, upper gastrointestinal endoscopic submucosal dissection is widely used in the treatment of various benign gastrointestinal tumors and early gastric cancer. However, upper gastrointestinal endoscopy is extremely irritating to the throat, and patients often cannot tolerate it and choose painless endoscopy or treatment under anesthesia. However, ordinary masks or nasal cannula oxygen inhalation may cause ventilation difficulties for patients with obesity, edentulism, cervical spondylosis, etc., and endoscopic treatment is often difficult to operate, the operation time is relatively long, the incidence of perforation and bleeding is high, and there is a risk of reflux aspiration. Before 2016, endotracheal intubation was routinely performed under general anesthesia, and endotracheal intubation has a strong harmful stimulation to the airway, requires a deeper level of anesthesia, and has a high incidence of postoperative airway injury. Therefore, a laryngeal mask that can improve patient comfort and satisfaction and reduce discomfort during medical treatment has high practicality.

When the mask is placed in the throat of the patient, the endoscope is introduced through the through hole provided at one end of the connecting handle, and the endoscope passes through the through hole into the through groove, and goes deep into the throat of the patient from the edge of the mask along the through groove, so that the endoscope can smoothly pass through the mask when the mask is used. At the same time, the mask is connected to the ventilator through the air inlet pipe to provide breathing for the patient, ensuring normal ventilation, thereby reducing irritation to the throat;

(2) A suction lumen is also provided at one end of the connecting handle, and a drainage groove is provided on the inner side of the mask bag. The drainage groove and the suction lumen form a sealed cavity, and the negative pressure suction device is connected to the suction lumen. When the patient has reflux, foreign matter is sucked into the suction lumen through the drainage groove on the inner side of the mask bag, and then sucked out through the suction lumen, thereby avoiding the risk of aspiration caused by foreign matter.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: an improved laryngeal mask, including a mask bag 1 and a connecting handle 2, the connecting handle 2 is fixedly connected to the top of the mask bag 1, the connecting handle 2 and the back of the mask bag 1 are provided with a groove 3, one end of the groove 3 extends to the edge of the mask bag 1, one end of the connecting handle 2 is provided with a hole 4, the hole 4 is connected to the groove 3, one side of the connecting handle 2 is connected to an air inlet pipe 5, the air inlet pipe 5 is connected to the mask bag 1, and the surface of the mask bag 1 is connected to an inflation joint 6.

During specific use: a groove 3 is opened on the back of the mask bag 1 and the connecting handle 2, and one end of the groove 3 extends all the way to the edge of the mask bag 1. When the mask bag 1 is placed in the patient's throat, the endoscope is introduced from the perforation 4 opened at one end of the connecting handle 2. The endoscope passes through the perforation 4 and enters the groove 3, and goes deep into the patient's throat from the edge of the mask bag 1 along the groove 3, so that when the mask bag 1 is used, the endoscope can also be ensured to pass through the mask bag 1 smoothly. At the same time, the mask bag 1 is connected to the ventilator through the air inlet pipe 5 to provide breathing for the patient, ensuring normal ventilation, thereby reducing irritation to the throat.

In this embodiment: one end of the inflation joint 6 is connected to an inflation tube 7 , and a manual valve 8 is installed on the surface of the inflation tube 7 .

During specific use: one end of the inflation connector 6 is connected to the inflation tube 7, and the inflation tube 7 is connected to the inflation device to inflate the mask bag 1, so that the mask bag 1 forms a seal in the patient's throat, and the mask bag 1 provides breathing for the patient. A manual valve 8 is installed on the surface of the inflation tube 7. By adjusting the manual valve 8, the mask bag 1 can maintain the inflated state after being inflated. When use is over, the manual valve 8 is adjusted to release the gas inside the mask bag 1, so that the mask bag 1 is completely deflated, which is convenient for taking it out from the throat.

In this embodiment: one end of the connecting handle 2 is located on one side of the perforation 4 and is provided with a suction lumen 9, and the inner side of the mask bag 1 is provided with a drainage groove 10, which corresponds to the suction lumen 9 and is connected to form a sealed cavity.

During specific use: a suction lumen 9 is also opened at one end of the connecting handle 2, and a drainage groove 10 is opened on the inner side of the mask bag 1. The drainage groove 10 and the suction lumen 9 form a sealed cavity, and the negative pressure suction device is connected to the suction lumen 9. When the patient has reflux, foreign matter is sucked into the suction lumen 9 through the drainage groove 10 on the inner side of the mask bag 1, and then extracted through the suction lumen 9, avoiding the risk of accidental aspiration caused by foreign matter.

In this embodiment, the cuff 1, the connecting handle 2 and the inflation tube 7 are all made of silicone material.

During specific use: the mask bag 1, the connecting handle 2 and the inflation tube 7 are made of silicone material. Silicone has good softness and can avoid damage to the laryngeal airway and reduce the pain of the patient.

Working principle: When the mask bag 1 is placed at the patient's throat, the endoscope is introduced from the perforation 4 opened at one end of the connecting handle 2, and the endoscope passes through the perforation 4 into the groove 3, and goes deep into the patient's throat from the edge of the mask bag 1 along the groove 3, so that when the mask bag 1 is used, the endoscope can also be ensured to pass through the mask bag 1 smoothly. At the same time, the mask bag 1 is connected to the ventilator through the air inlet pipe 5 to provide breathing for the patient and ensure normal ventilation, thereby reducing stimulation to the throat area, and connecting the negative pressure suction device to the suction lumen 9. When the patient has reflux, foreign matter is sucked into the suction lumen 9 through the drainage groove 10 on the inner side of the mask bag 1, and is sucked out through the suction lumen 9 to avoid the risk of aspiration caused by foreign matter.
