Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an oropharyngeal ventilation mouthpiece for gastroscopy and electroconvulsive therapy. Background Technology

[0002] During gastroscopy and electroconvulsive therapy (ECT), a mouthpiece is required to prevent biting injuries during endoscopic intubation and ECT. However, existing mouthpieces only have one opening. In practice, obese patients or those with other airway problems may experience difficulty breathing due to tongue retraction or other airway obstructions after anesthesia. In such cases, in addition to the pre-inserted mouthpiece, resuscitation measures such as oropharyngeal airways are necessary. Because existing mouthpieces only have one channel for gastroscopic intubation, when an oropharyngeal airway is needed simultaneously, the mouthpiece design limitation prevents the airway from entering the oropharyngeal airway once the endoscope is inside. The endoscope must be withdrawn from the mouthpiece to allow resuscitation, thus preventing the gastroscopy from being performed. This is not only inconvenient but also increases the difficulty of patient resuscitation, may damage the endoscope, and could cause oral injuries, posing operational risks. Therefore, an improved oropharyngeal ventilation mouthpiece is urgently needed to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a gastroscopy mouthpiece that can also allow ventilation, in order to solve the problem of inconvenient insertion of oropharyngeal ventilation tubes during gastroscopy in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is an oropharyngeal ventilation mouthpiece, including an oropharyngeal ventilation tube and a mouthpiece; the mouthpiece includes a mouth pad, a bite block, a breathing channel tube, and a gastroscopy channel tube. The bite block is directly formed on the inner surface of the mouth pad. The breathing channel tube passes directly through and is formed at a position slightly to the left or right of the center of the mouth pad and the bite block, extending beyond the inner surface of the bite block. The gastroscopy channel tube passes directly through and is formed at a position slightly to the right or left of the center of the mouth pad and the bite block, extending beyond the inner surface of the bite block. The breathing channel tube and the gastroscopy channel tube are closely attached and parallel; that is, the breathing channel tube and the gastroscopy channel tube are parallel and closely attached to each other, passing directly through and forming at the center of the mouth pad and the bite block. The mouth pad, the bite block, the breathing channel tube, and the gastroscopy channel tube are integrally formed. The oropharyngeal airway includes a directly connected rim, an oral cavity tube, and a pharyngeal tube. The outer diameter of the oral cavity tube is equal to or slightly smaller than the inner diameter of the airway tube, and the length of the oral cavity tube is equal to or greater than the length of the airway tube. When the airway tube is located to the left of the endoscope tube, the right side of the rim has no edge to avoid obstructing the closely attached endoscope tube. When the airway tube is located to the right of the endoscope tube, the left side of the rim has no edge. The oropharyngeal airway is detachably inserted into the airway tube. This close proximity of the endoscope tube and the airway tube on the mouthpiece greatly reduces the space required for insertion into the patient's mouth, significantly reducing patient discomfort. It also reduces the difficulty of operation for medical staff and speeds up the surgical process.

[0005] The mouthpiece, dental pad, breathing channel tube, and gastroscopy channel tube are all made of medical-grade silicone or polypropylene plastic and are designed for single-use applications.

[0006] The mouth rim, oral cavity tube, and pharyngeal tube are all integrally formed from medical-grade silicone or polypropylene plastic; they are for single use only in practical applications.

[0007] The dental pad is an oval cylinder, and its shape and size are suitable for the patient's oral cavity.

[0008] The dental pad is provided with a limiting groove, which is used by the patient to bite into the groove and prevent the patient's tongue from pushing the mouthpiece out.

[0009] The mouth pad is oval-shaped with an inward curvature that matches the curvature of the lips so as to fit snugly against the patient's lips.

[0010] The pharyngeal tube is a flat, curved tube that conforms to the structure of the pharynx and larynx.

[0011] Each side of the mouth pad has an ear hole, and an elastic band is installed in the ear hole to fix it to the back of the patient's head and neck.

[0012] The beneficial effects of this invention are: a single bite can simultaneously insert the gastroscopy tube and the oropharyngeal ventilation tube, which can greatly reduce patient discomfort and the possibility of damaging the patient's oral cavity, while also bringing great convenience to the surgeon; the use of an integrated bite structure can reduce the complexity of the operation, and single use can avoid cross-infection and reduce the labor intensity of medical staff.

[0016] The present invention will be further described below with reference to the embodiments.

[0017] The existing endoscope mouthpiece includes a mouthplate 3, a bite block 4, and an endoscope channel tube 6. The bite block 4 is directly formed at the center of the inner surface of the mouthplate 3, and the endoscope channel tube 6 passes directly through it, forming at the center of the mouthplate 3 and the bite block 4 and extending beyond the inner surface of the bite block 3. This mouthpiece does not consider the installation position of the oropharyngeal airway, making surgical procedures very inconvenient. This embodiment improves upon this design.

[0018] As shown in the figure, an oropharyngeal ventilation mouthpiece is fabricated, including a mouthpiece 1 and an oropharyngeal ventilation tube 2. The mouthpiece 1 includes a mouth pad 3, a bite block 4, a breathing channel tube 5, and a gastroscopy channel tube 6. The mouth pad 3 is elliptical and has an inward curvature that matches the curvature of the lips to ensure a close fit to the patient's lips. The bite block 4 is an elliptical cylinder whose shape and size are suitable for the patient's oral cavity. The bite block 4 is directly formed on the inner surface of the mouth pad 3. The breathing channel tube 5 passes directly through the mouth pad 3 and is formed slightly to the left of the center of the mouth pad 3 and the bite block 4. The endoscope tube 6 extends beyond the inner side of the mouthpiece 4 and passes directly through it, forming a position slightly to the right of the center of the mouthpiece 3 and the mouthpiece 4, extending beyond the inner side of the mouthpiece 4. The breathing tube 5 and the endoscope tube 6 are closely attached and parallel; that is, the breathing tube 5 and the endoscope tube 6 are parallel and closely attached to each other, passing directly through and forming a position at the center of the mouthpiece 3 and the mouthpiece 4. The mouthpiece 3, the mouthpiece 4, the breathing tube 5, and the endoscope tube 6 are all integrally formed into the mouthpiece 1 using medical-grade silicone material or polypropylene plastic; the oropharyngeal airway 2 It includes a directly connected oral rim 7, oral tube 8, and pharyngeal tube 9. The outer diameter of the oral tube 8 is 90%-100% of the inner diameter of the respiratory channel tube 5, and the length of the oral tube 8 is 100%-200% of the length of the respiratory channel tube 5. When the respiratory channel tube 5 is located to the left of the gastroscopy channel tube 6, the right side of the oral rim 7 has no edge to avoid obstructing the closely attached gastroscopy channel tube 6. When the respiratory channel tube 5 is located to the right of the gastroscopy channel tube 6, the left side of the oral rim has no edge. The pharyngeal tube 9 is a flat curved tube conforming to the structure of the pharynx and larynx. The mouth rim 7, oral cavity tube 8, and pharyngeal tube 9 are all integrally formed from medical-grade silicone or polypropylene plastic to create the oropharyngeal airway 2. The oropharyngeal airway 2 is detachably inserted into the breathing channel tube 5, with the pharyngeal tube extending beyond the breathing channel tube 5. This close-fitting arrangement of the endoscope tube 6 and the breathing channel tube 5 onto the mouthpiece 1 greatly reduces the space required for the endoscope tube and oropharyngeal airway 2 to be inserted into the patient's mouth during surgery, significantly reducing patient discomfort. It also reduces the operational difficulty for medical staff and speeds up the surgical process.

[0019] As described above, the dental pad 4 is provided with a limiting dental groove 10, which is used for the patient to bite into the limiting dental groove to prevent the patient's tongue from pushing the mouthpiece out; each side of the mouth pad 3 is provided with an ear hole 11, and an elastic band 12 is installed in the ear hole 11 to fix it to the back of the patient's head and neck.

[0020] During use, the doctor puts an oropharyngeal ventilation mouthpiece on the patient, places the breathing tube 5 and the gastroscopy tube 6 in the patient's mouth, places the bite block 4 between the upper and lower teeth, and embeds the patient's teeth into the limiting alveolar 10, so that the mouth pad 3 is attached to the patient's lips, and then the elastic band 12 is used to stabilize the patient's head; then the oropharyngeal ventilation tube 2 is passed through the breathing tube 5 and placed in the patient's mouth and throat, and then the gastroscopy is passed through the gastroscopy tube 6 to perform a gastroscopy. This not only improves the convenience of the operation, but also reduces the patient's discomfort and potential operational risks.
