Description

Technical Field

[0001] The utility model relates to a mouthpiece for use with a gastroscope and an auxiliary ventilation structure thereof, belonging to the field of medical auxiliary equipment. Background Art

[0002] With the advancement of endoscopic diagnosis and treatment technology, gastroscopy has become the preferred method for examining and treating digestive system diseases, and is widely used by medical institutions and health management centers at all levels across the country. Gastroscopy is a medical examination method, and also refers to the instrument used for this examination. It uses a thin, soft tube to extend into the stomach, so that doctors can directly observe lesions in the esophagus, stomach and duodenum, especially tiny lesions. Gastroscopy can directly observe the true condition of the examined area, and can further clarify the diagnosis by performing pathological biopsy and cytological examination on suspected lesions. It is the preferred examination method for upper gastrointestinal tract lesions. The development of painless gastroscopy has brought convenience to patients and clinical medical staff, and has also improved the accuracy and detection rate of disease diagnosis.

[0003] During gastroscopy, the patient takes a side-lying position and is often used with short-term intravenous general anesthesia for painless gastroscopy. During gastroscopy, the patient needs to hold a mouthpiece in his mouth for assistance, so that the patient's mouth forms a stable channel, which is convenient for inserting the gastroscope tube for examination and can prevent the patient's teeth from biting the gastroscope tube. Because the oral ventilation channel needs to be occupied during gastroscopy, in order to maintain the patient's respiratory tract management during intravenous general anesthesia, the current examination process is mainly ventilated through the nasal cavity, but the upper respiratory tract obstruction caused by the tongue falling back of obese patients brings troubles to gastroenteroscopists and anesthesiologists, and also increases the risk to patients.

[0004] The Chinese utility model patent with application number CN201921152474.2 discloses a gastroscope mouthpiece with a device for fixing a tracheal tube, which has two half rings in the vent on one side of the mouthpiece. When not in use, the two half rings are separated. After the tracheal tube is inserted, the connecting ring is removed, and the two half rings can fix the tracheal tube to prevent it from shifting. The Chinese utility model patent with application number CN202022700372.9 discloses a gastroscope mouthpiece through which the trachea and gastroscope can pass, which solves the problem that the mouthpiece in the mouth of a patient under general anesthesia is easily displaced or even falls off during operation, and is suitable for patients under general anesthesia who need to undergo tracheal intubation and gastroscopy at the same time. The Chinese utility model patent with application number 2019223114611 discloses a disposable mouthpiece for gastroscopy in the Department of Gastroenterology, wherein an inner tube is provided inside the mouthpiece, and an oxygen tube jack and a gastroscope tube jack are provided on the inner tube, which can draw away saliva and also provide oxygen when the patient has difficulty breathing. However, the endotracheal intubation pathway structures of the three are relatively complex and inconvenient to use.

[0025] like Figure 1-Figure 4As shown: a mouthpiece for gastroscope, the mouthpiece for gastroscope is used to provide a passage for gastroscope insertion during gastroscopy, and is mainly used to fix the patient's oral cavity, ensure the accuracy of gastroscopy and prevent the patient from causing discomfort or accidental injury during the examination. The mouthpiece includes a mouthpiece body and a strap 1 connected to the mouthpiece body. The mouthpiece body is made of soft material, such as medical silicone, and has good elasticity and durability; the strap 1 is used to fix the mouthpiece body on the patient's head, and is made of an adjustable strap or tape, which can adapt to the head size of different patients.

[0026] The mouthpiece body includes a panel 2 and a bite tube 3 disposed on the panel 2. The bite tube 3 is used to provide a gastroscope passage for the insertion of a gastroscope during gastroscopy. The mouthpiece body also includes an oropharyngeal passage tube 4. The oropharyngeal passage tube 4 is fixed to the panel 2 and is located on one side of the bite tube 3. The oropharyngeal passage tube 4 is used to provide a passage for the insertion of an oral cigarette tube and has a certain fixing and guiding effect on the oral cigarette tube. The end of the oropharyngeal passage tube 4 located on the inner side of the panel 2 does not exceed the bite tube 3, thereby improving the comfort of the patient. The panel 2, the bite tube 3 and the oropharyngeal passage tube 4 can be an integrated structure. The bite tube 3 and the oropharyngeal passage tube 4 are adjacent. The size of the oropharyngeal passage tube 4 is suitable for passing through various oropharyngeal tubes, and can be various shapes such as round and prismatic.

[0027] In this embodiment, an elastic resistance layer 5 is provided in the oropharyngeal passage tube 4, and the elastic resistance layer 5 is provided around the inner wall of the oropharyngeal passage tube 4. The elastic resistance layer 5 is composed of a plurality of small elastic columns protruding from the inner wall of the oropharyngeal passage tube 4. When the oral cigarette tube is inserted into the oropharyngeal passage tube 4, the elastic resistance layer 5 contacts the oral cigarette tube and provides resistance to prevent the oral cigarette tube from shifting. The elastic resistance layer 5 can also be an elastic silicone (or rubber) sleeve, etc.

[0028] Example 2

[0029] like Figure 4 As shown: This embodiment provides an auxiliary ventilation structure for the mouthpiece used with the gastroscope described in Example 1, specifically including an oral cigarette tube, the oral cigarette tube is inserted into the oropharyngeal passage tube 4, and the elastic resistance layer 5 is coated on the outer wall of the oral cigarette tube to provide resistance to prevent the oral cigarette tube from shifting (because the oral cigarette tube and the gastroscope are both inserted through the oral cavity, when the gastroscope is advanced, retreated or rotated, if the oral cigarette tube is not firmly fixed, the catheter may shift, thereby causing the oral cigarette tube to enter too deeply or slip, and normal ventilation cannot be achieved, posing a safety hazard.).

[0030] The oral cigarette tube includes a pipeline 6 and an end 7 arranged on the pipeline 6 and connected to the pipeline 6. The pipeline 6 is a hollow pipe, which can be circular, prismatic, etc. A baffle 8 is provided on one opposite side of the end 7. The pipeline 6 is inserted into the oropharyngeal passage tube 4, and the end 7 is stuck outside the oropharyngeal passage tube 4 by the baffle 8 to prevent the oral cigarette tube from being excessively inserted. The end 7 includes an oxygen supply connector 9 and a ventilator connector 10, which are respectively used to connect the oxygen supply mechanism (such as an oxygen generator) and the ventilator. The end 7 forms a three-way structure, and the ventilator connector 10 is connected to the ventilator. For patients who need high-frequency air, it is connected to the main ventilator. For general patients, it is connected to the oxygen supply connector 9 for oxygen. Either one of them can be used, and they cannot be used at the same time.

[0031] The oral cigarette tube also includes a balloon 11 and an air-filling and air-discharging tube 12. The balloon 11 is arranged on the pipeline 6. The balloon 11 is used to adjust the position of one end of the oral cigarette tube in the patient. One end of the air-filling and air-discharging tube 12 extends out of the terminal 7, and the other end is connected to the balloon 11. The air-filling and air-discharging tube 12 is used to inflate and deflate the balloon 11. The balloon 11 is arranged on one side of the pipeline 6 to prevent the pipeline 6 from being close to the patient's inner cavity (because the oral cigarette tube is just a single tube extending into the patient's interior, the end of the tube will be on one side of the human body's inner cavity and cannot be centered, affecting the use. The balloon 11 is added to the end of the tube, and the balloon 11 is on one side of the end of the tube, which props up the end of the tube and places it in the middle of the human body's internal passage), while not affecting the gastroscopy operation; the balloon 11 and the oxygen supply connector 9 are located on the same side of the oral cigarette tube, and the side where the balloon 11 is located and the side where the oxygen supply connector 9 is located are on the same side, which is convenient for judging the position of the side where the balloon 11 is located after the oropharyngeal tube is extended into the human body.

[0032] When using the mouthpiece and auxiliary ventilation structure of the gastroscope provided in this application, first let the patient bite the mouthpiece body, and fix the mouthpiece body by the strap 1 (the strap 1 is fixed to the patient's head), then extend the gastroscope into the patient's body through the bite tube 3, and extend the oral cigarette tube (auxiliary ventilation structure) into the patient's body through the oropharyngeal passage tube 4, and judge the position of the balloon 11 by the position of the oxygen supply connector 9, so that the balloon 11 is attached to the human body cavity, and then inflate the balloon 11 through the inflation and deflation tube 12, and choose whether to connect the oral cigarette tube to the ventilator or oxygen concentrator according to the patient's condition. After the examination is completed, deflate the balloon 11 through the inflation and deflation tube 12, withdraw the oral cigarette tube, and then withdraw the gastroscope. In the above process, there is no restriction on the order of insertion or withdrawal of the gastroscope and the oral cigarette tube.

[0033] In addition, in the description of the present invention, unless otherwise specified, the terms "multiple", "multiple roots", "multiple groups" mean two or more than two, and "several", "several roots", "several groups" mean one or more than one. In the description of the present invention, it should be noted that the orientation or position relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
