Description

Technical Field

[0001] The utility model belongs to the field of medical technology, in particular to an oral endoscopic mouthpiece capable of monitoring end-tidal carbon dioxide and administering oxygen. Background Art

[0002] During digestive endoscopy and bronchoscopy under deep sedation or anesthesia, one of the main monitoring indicators is pulse oximetry. Pulse oximetry mainly reflects the body's lung ventilation function. Deep sedation or anesthesia can often cause respiratory depression in patients, manifested as insufficient ventilation such as a significant decrease in respiratory rate and amplitude, or even respiratory arrest. End-tidal carbon dioxide monitoring of respiratory depression under deep sedation or anesthesia is more sensitive than pulse oximetry, and can detect and promptly treat this type of respiratory depression earlier, and significantly reduce the incidence and severity of hypoxemia. Currently, there is no clinical device that can monitor end-tidal carbon dioxide when patients exhale through both the nose and mouth, and can also provide oxygen.

[0003] According to a publicly disclosed oral endoscopic mouthpiece for monitoring end-tidal carbon dioxide and providing oxygen (publication number: CN208973797U), it includes a sampling catheter and an oxygen supply catheter, as well as a nasal suction tip that can be connected to the patient's nose and a mouthpiece that can be connected to the patient's mouth. The nasal suction tip is connected to the sampling catheter and the oxygen supply catheter, respectively, and the mouthpiece is connected to the sampling catheter. This oral endoscopic mouthpiece has a compact structure and is easy to use. It can be used to monitor end-tidal carbon dioxide in patients during digestive endoscopy and (bronchial) bronchoscopy procedures under deep sedation or anesthesia. Whether the patient exhales through the nose or mouth, end-tidal carbon dioxide can be collected and oxygen can be provided to the patient at the same time. It is suitable for different patients and has the characteristics of low cost, high safety, and easy production.

[0004] However, the above application cannot adjust the distance of the mouthpiece through the mutual cooperation between the mouthpiece and the sampling tube. The application is limited to a limited number of people when used for a long time, and the effect is not ideal. Utility Model Content

[0036] A specific application of this embodiment is: when it is necessary to examine the patient's cavity, first put the mouthpiece 46 into the patient's mouth, and then start the motor 41. When the motor 41 is started, the threaded rod 43 on the output shaft of the motor 41 rotates clockwise. When the threaded rod 43 rotates clockwise, the threaded sleeve 44 on the threaded rod 43 moves outward. When the threaded sleeve 44 moves outward, the mouthpiece 46 connected to the threaded sleeve 44 through the connecting frame 45 moves outward. When debugging is completed, turn off the motor 41. At this time, the debugging effect is achieved. When the inspection is completed, the threaded rod 43 rotates counterclockwise. When the threaded rod 43 rotates counterclockwise, the threaded sleeve 44 on the threaded rod 43 moves inward. When the threaded sleeve 44 moves inward, the mouthpiece 46 connected to the threaded sleeve 44 through the connecting frame 45 moves inward. When the mouthpiece 46 moves inward, the doctor can remove the mouthpiece 46, and the cavity cannot be inspected at this time.

When an object is placed inside the disinfection box 51, the disinfection box 51 moves downward due to gravity. When the disinfection box 51 moves downward, it collides with the force rod 57 of the hydraulic cylinder 56. When the force rod 57 is collided, the hydraulic rod 58 moves upward horizontally. When the hydraulic rod 58 moves upward horizontally, the push plate 59 on the hydraulic rod 58 moves upward horizontally. When the push plate 59 moves upward horizontally, the disinfectant inside the storage box 53 is pushed into the disinfection box 51. At this time, the disinfection effect is achieved. When disinfection is completed, the mouthpiece 46 is taken out. When the mouthpiece 46 is taken out from the disinfection box 51, the disinfection box 51 moves upward due to gravity. When the disinfection box 51 moves upward, it will not collide with the force rod 57 of the hydraulic cylinder 56. When the force rod 57 is not collided, the hydraulic rod 58 will not move upward horizontally, and disinfection cannot be performed at this time.
