Description

Multifunctional endoscope mouth pad

technical field

The present invention relates to a mouth pad, in particular, to a multifunctional endoscope mouth pad.

Background technique

With the continuous development of endoscopic technology and the continuous improvement of its accessories, gastroscope and duodenoscopy have become important examination and treatment measures for upper gastrointestinal and hepatobiliary and pancreatic diseases, such as early esophageal cancer, gastric cancer, and common bile duct stones , acute obstructive suppurative cholangitis, bile duct injury, bile duct stricture, biliary complications after liver transplantation, etc. Compared with traditional laparotomy, this technique has the advantages of less trauma, higher safety factor, and faster recovery. Oropharyngeal mucosal anesthesia or intravenous anesthesia are often used in endoscopic techniques. In order to facilitate intubation and avoid dental damage to the endoscope, an oral pad should be placed in the oral cavity before surgery. In order to avoid the occurrence of hypoxemia, it is necessary to wear an oxygen inhalation tube for oxygen inhalation before surgery; under the stimulation of the endoscope, the oral mucosa and salivary glands will secrete a large amount of saliva, and the gag reflex will cause a large amount of gastric acid to flow back into the oral cavity, resulting in false Suction occurs.

At present, the mouth pad, oxygen inhalation tube and negative pressure suction tube are all used alone. The patient bites the mouth pad and fixes it behind the pillow with an elastic cord. The mouth pad is relatively fixed and rarely shifts. The head end of the oxygen inhalation tube needs to be inserted into the nostril, and the oxygen inhalation tube is fixed behind the pillow through the upper edge of the auricle. There are the following deficiencies in clinical operation: 1. The head and face are pressed on the oxygen inhalation tube, and the head end of the oxygen inhalation tube is easy to be inserted too deep or one side is displaced, which damages the nasal mucosa or causes a sneezing reaction, which affects the endoscopic operation; 2. Oxygen inhalation Under the action of gravity, the head end of the tube is easily prolapsed or displaced from the nostril, resulting in hypoxia of the patient, and the operation of adjusting or relocating the oxygen inhalation tube during the operation is cumbersome and affects the operation process; 3. The oxygen inhalation tube passes above the auricle. It is fixed on the occiput, which affects the fixation of the nasobiliary duct. It is necessary to remove the oxygen inhalation tube and then fix the nasobiliary duct, which will affect the patient's oxygen inhalation; 4. The oxygen inhalation tube can only be fed through the nasal cavity, and some patients are obstructed or used to pass through the mouth. Breathing, which leads to less nasal feeding and absorption, and currently lacks oral feeding; 5. The oral cavity secretes a lot of saliva, and a lot of gastric acid and bile will be vomited when vomiting. Suction occurs. At present, there are large saliva passage holes on the front guard plate of the mouth pad, but the saliva is viscous and difficult to flow out on its own. The clinical workload also delayed the progress of surgical operations.

SUMMARY OF THE INVENTION

According to the clinical operation proposed above, the head and face are pressed on the oxygen inhalation tube, and the head end of the oxygen inhalation tube is easy to be inserted too deep or one side is displaced, which may damage the nasal mucosa or cause a sneezing reaction, which affects the endoscopy operation; Under the action of gravity, it is easy to be prolapsed or displaced from the nostrils, resulting in hypoxia of the patient, and the operation of adjusting or relocating the oxygen inhalation tube during the operation is cumbersome and affects the operation process; the oxygen inhalation tube is fixed on the occiput above the auricle, Affecting the fixation of the nasobiliary duct, it is necessary to remove the oxygen inhalation tube and then fix the nasobiliary duct, thereby affecting the patient’s oxygen inhalation; the oxygen inhalation tube can only be fed through the nasal cavity, and some patients have occlusion or are used to breathing through the mouth, resulting in poor nasal feeding and absorption. At present, there is a lack of oral support; the oral cavity secretes a large amount of saliva, and a large amount of gastric acid and bile will be vomited when vomiting. There is a large saliva passage hole on the guard plate, but the saliva is viscous and difficult to flow out on its own. If the suction is not timely during the operation, it may lead to the occurrence of aspiration, which not only increases the clinical workload of the endoscopist, but also delays In order to solve the technical problem of the progress of the surgical operation, a multifunctional endoscope mouth pad is provided. The invention mainly adopts an integrated design of the oxygen inhalation tube, the negative pressure suction tube and the mouth pad, which makes wearing and oxygen inhalation more convenient, and can avoid the displacement of the oxygen inhalation tube; Realize the simultaneous supply of oxygen through the nasal cavity and the oral cavity; by setting the silicone ring, a closed space is formed between the guard plate on the front side of the bite part and the peripheral skin of the oral cavity, so that the oral saliva, vomited bile, gastric acid and other liquids can be sucked out in time to avoid mistakes. Suction occurs.
