[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0026] In this application, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] Existing devices usually use a hose that is inserted into the patient's mouth, a tooth pad is set on the hose for the patient to bite, and a negative pressure device is set at the other end of the hose to guide the patient's oral secretions. At the same time, the setting of the tooth pad prevents the hose from easily falling off from the patient's mouth.

[0028] In the related art, different patients' mouths can open and close to different degrees, and the size of the tooth pads in existing devices is fixed. The opening and closing angles of some patients' teeth do not match the tooth pads, which causes the patients' oral mucosa to be scraped, causing discomfort or even damage, and has certain limitations.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an oral secretion guide tube. When the medical staff performs bronchoscopy on the patient, they first hold the hose 14 with one hand and control the sliding sleeve 21 with the other hand to drive the plate 22 to slide on the hose 14 toward the protective head 26. After sliding to a certain position, the patient opens his mouth. The medical staff turns the screw disk 241 on the original fixed position counterclockwise according to the degree of opening and closing of the patient's mouth to loosen the bolt 24 and remove it. The user then manually controls the rod body 23 Lift and lower on the preset empty slot on the plate body 22, and make the top of the tooth pad 25 close to the top position of the patient's mouth opening and closing range, and then look at the position of the second fixing hole 231 on the rod body 23. If the second fixing hole 231 coincides with the first fixing hole 221, directly use the screw plate 241 and the bolt 24 to pass through the fixing holes to fix the rod body 23 on the plate body 22. If the two fixing holes do not coincide, select the second fixing hole 231 closest to the first fixing hole 221 and use the screw plate 241 and the bolt 24 to pass through the two fixing holes to fix the two.

[0030] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0031] Combine Figure 1-Figure 2 , the embodiment of the present application provides an oral secretion guide tube, including a guide device 1; the guide device 1 includes: a connecting pipe 12 is provided on the top of the tee head 11; a connecting pipe 2 13 is provided at the bottom of the tee head 11; a hose 14 is provided on the tee head 11; an adjusting device 2 is provided on the guide device 1, and the adjusting device 2 includes: a sliding sleeve 21 is slidably provided on the hose 14; a plate body 22 is sleeved on the sliding sleeve 21, and a fixing hole 1 221 is provided on the plate body 22; a rod body 23 is symmetrically provided on the plate body 22, and the rod body 23 and the plate body 22 are plugged into each other, a fixing hole 231 is provided on the rod body 23, and a tooth pad 25 is provided on the top of the rod body 23; a bolt 24 is provided through the fixing hole 1 221 and the fixing hole 2 231, and the other end of the bolt 24 is threaded with a screw disk 241.

[0032] When performing bronchoscopy on a patient, the medical staff first holds the hose 14 with one hand and controls the sliding sleeve 21 with the other hand to drive the plate 22 to slide on the hose 14 toward the protective head 26. After sliding to a certain position, the patient opens his mouth. The medical staff turns the screw disk 241 on the original fixed position counterclockwise according to the degree of opening and closing of the patient's mouth to loosen and remove the bolt 24. The user then manually controls the rod 23 to rise and fall on the preset slot on the plate 22, and brings the top of the bite pad 25 close to the top position of the patient's mouth opening and closing range. Then, the position of the second fixing hole 231 on the rod 23 is checked. If the second fixing hole 231 coincides with the first fixing hole 221, the patient can use the plate 22 directly. The screw disc 241 and the bolt 24 pass through the fixing hole to fix the rod body 23 on the plate body 22. If the two fixing holes do not overlap, select the fixing hole 231 closest to the fixing hole 1 221 and use the screw disc 241 and the bolt 24 to pass through the two fixing holes to fix the two. After the adjustment is completed, the patient holds the protective head 26 in his mouth and bites the bite pad 25 with his teeth. The medical staff then connects the suction tube to the connecting pipe 12 to connect the bronchoscope (to provide negative pressure), and connects the outlet of the suction device liner to the connecting pipe 2 13. After turning on the switch, the patient's oral secretions are guided through the hose 14 and flow out from the connecting pipe 2 13. The medical staff controls the bronchoscope to enter the patient's nasal cavity for examination.

[0033] In some embodiments, the hose 14 is provided with a valve 28. The valve 28 is a medical valve consisting of a rotating rod, a connecting port, and a plug. After oral secretions flow through the hose 14, the user turns the rotating rod on the valve 28 counterclockwise to rotate the plug thread upward, exposing the internal slot of the valve 28, thereby unblocking the hose 14 and allowing secretions to pass through. Conversely, turning the rotating rod clockwise moves the plug thread downward to block the internal slot of the valve 28.

[0034] In some embodiments, the head of the hose 14 is provided with a protective head 26. The protective head 26 encloses the hose 14. When diverting oral secretions, the hose 14 enters the patient's oral cavity, and the patient holds the protective head 26 in his mouth to prevent the patient's oral mucosa from being scratched.

[0035] In some embodiments, the protective head 26 is provided with a drainage groove 27 that is connected to the hose 14. The protective head 26 is provided with four drainage grooves 27 around it, and multiple drainage holes are provided inside the drainage grooves 27. The provision of the drainage grooves 27 can prevent the drainage holes from directly contacting the patient's oral mucosa under negative pressure, which may cause bleeding in the patient's mouth due to the negative pressure. The front end of the protective head 26 is also provided with drainage holes. The patient's oral secretions pass through the drainage holes, pass through the protective head 26, and then enter the hose 14 for collection, thereby improving the collection efficiency of the entire device.

[0036] In some embodiments, the bolt 24 and the screw disk 241 are made of medical silicone material, which meets the hygiene requirements of bronchoscopy and has good deformation resistance and is not easily damaged.

[0037] In some embodiments, three second fixing holes 231 are provided, and the three second fixing holes 231 are spaced 5 mm apart. Based on the fact that the normal mouth opening range for a person is between 25 mm, 30 mm, and 35 mm, setting the three second fixing holes 231 5 mm apart can best match the mouth opening range of different patients and reduce discomfort for patients during bronchoscopy.

[0038] In some embodiments, auxiliary rods 29 are symmetrically provided at the bottom of the tooth pad 25, and the auxiliary rods 29 are slidably connected to the plate body 22. The provision of the auxiliary rods 29 improves the stability of the rod body 23 when it moves, thereby enhancing the structural integrity of the entire device and strengthening the stability of the entire device.

[0039] In some embodiments, the top of the bite pad 25 is provided with a plurality of grooves 251. The top of the bite pad 25 is a soft silicone layer. The silicone layer prevents the patient's teeth from being hurt when biting the bite pad 25. The plurality of grooves 251 provided on the top of the bite pad 25 can accommodate the patient's teeth, preventing the bite pad 25 from slipping due to oral secretions when the patient bites the bite pad 25, thereby improving the patient's user experience.
