[0016] Principle and beneficial effects of this technical solution:

[0017] (1) The sealing assembly provided in the present invention can seal the gap between the patient's nasal cavity and the endoscope body and the oxygen tube during the patient's endoscopy. At the same time, the mask body is set to be open, directly avoiding the condensation of the water column that may be caused by the patient's exhaled gas. When using the mask body, first fix the mask body to the patient's face through elastic drawstrings or the like, and align the first connection port and the second connection port with the patient's two nostrils respectively. Then, the oxygen tube and the endoscope body can be inserted into the patient's nasal cavity through the first connection port and the second connection port opened at the top of the air guide cover respectively. While inserting, the control arm in the control assembly can be operated through the control button to rotate. The rotation of the control arm will drive the rotating plate to rotate between a set of fixed rings, compressing the torsion spring until the two elastic rings penetrated by the free end of the rotating plate respectively wrap around the outer sides of the oxygen tube and the endoscope body. At this time, the state of the sealing assembly is locked, and then the endoscope body can be controlled through the operation window opened on the outer side of the mask. When it is necessary to temporarily fix the endoscope body, the exposed part of the endoscope body can be snapped into the positioning groove opened at the top of the operation window for temporary positioning.

[0018] (2) The control assembly provided in the present invention can control the opening and closing of the sealing assembly. When it is necessary for the rotating plate in the sealing assembly to clamp the endoscope body and the oxygen tube respectively, pull the control button provided on the outer side of the control arm outwards. The first pull rope and the second pull rope connected to the inner side of the control arm will then pull the rotating plate connected to their free ends, causing the rotating plate to retract and clamp the endoscope body and the oxygen tube. During the process of pulling the first pull rope and the second pull rope, the limiting cover and the limiting plate will perform limiting control on the first pull rope and the second pull rope to prevent the oxygen tube and the endoscope body from touching and interfering with the movement of the first pull rope and the second pull rope.

[0019] (3) The air filter cylinder and the collection cylinder provided in the present invention can filter the gas exhaled by the patient respectively, and can also collect the foreign objects discharged from the patient's mouth due to irritation during the patient's examination. Connect a disposable mouthpiece to the connection mouth, and connect it to the patient's mouth through the mouthpiece. When the patient exhales, the gas exhaled by the patient will be discharged from the pipeline into the connecting pipe and finally discharged to the outside through the filter screen;

[0020] When foreign objects are discharged from the patient's mouth, since the connection part between the pipeline and the connecting pipe is higher than the connection part between the pipeline and the connection mouth, the foreign objects will flow along the inner wall of the connection mouth into the collection cylinder, and then the foreign objects are collected through the collection bag fixed at the bottom of the collection cylinder through the groove and the rubber gasket. At the same time, the valve prevents the foreign objects from being sucked back. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0027] The present invention will be further described in detail below with reference to the drawings and implementation manners:

[0028] Example:

[0029] As Figures 1 to 5 shown, the present invention provides a plastic auxiliary ventilation mask for endoscopic examination, including a mask body 3. A sealing component is arranged inside the mask body 3. The sealing component includes an air guide hood 10 arranged inside the mask body 3. The top of the air guide hood 10 is provided with a first connection port 15 and a second connection port 19. The first connection port 15 and the second connection port 19 are symmetric with respect to the central axis of the mask body 3. The inner diameters of the first connection port 15 and the second connection port 19 are equal and the heights are the same.

[0030] As Figure 4 shown, a plurality of groups of fixed rings 18 are evenly arranged at the tops of the first connection port 15 and the second connection port 19. A rotating plate 14 is rotatably connected between each group of fixed rings 18 through a torsion spring. Each rotating plate 14 is connected through a connecting film 13. The connecting film 13 is made of an elastic material.

[0031] As Figure 4 shown, two elastic rings 16 are respectively penetrated through the free ends of two groups of rotating plates 14 located at the first connection port 15 and the second connection port 19. When the rotating plate 14 is in the horizontal direction, the elastic ring 16 is in the initial state.

[0032] As Figures 3 to 5As shown, any two of the two groups of turning plates 14 are jointly connected with a control component. The control component includes a first pull rope 17 and a second pull rope 20 connected to the turning plate 14. The free ends of the first pull rope 17 and the second pull rope 20 are jointly connected with a turning arm 24. A control button 25 is arranged on the outer side of the turning arm 24. The turning arm 24 is rotationally clamped on a connecting block 23 arranged at the end of the air inlet pipe 12.

[0033] As Figures 3 to 5 shown, the bottom end of the second connection port 19 is connected with an air inlet pipe 12. The bottom end of the air inlet pipe 12 is clamped in an air inlet 26 opened on the outer side of the mask body 3. The first pull rope 17 is arranged inside the air inlet pipe 12. A limiting cover 22 is arranged inside the air inlet pipe 12. The limiting cover 22 covers the outer sides of the first pull rope 17 and the second pull rope 20. The top end of the limiting cover 22 is connected with a pair of limiting plates 21. The limiting plates 21 are respectively arranged on both sides of the first pull rope 17 and the second pull rope 20.

[0034] As Figure 1 and Figure 4 shown, a sealing film 1 is connected to the top end of the mask body 3. An operation window 4 is opened on the outer side of the mask body 3. A pair of positioning grooves 2 are opened on both sides of the top end of the operation window 4. The positioning grooves 2 and the operation window 4 are simultaneously communicated with the first connection port 15.

[0035] The control component can control the opening and closing of the sealing component. When it is necessary for the turning plates 14 in the sealing component to respectively clamp the lens body and the oxygen pipe, the control button 25 arranged on the outer side of the turning arm 24 is pulled outwards. The first pull rope 17 and the second pull rope 20 connected to the inner side of the turning arm 24 will then pull the turning plates 14 connected to their free ends, causing the turning plates 14 to retract and clamp the lens body and the oxygen pipe. During the process of pulling the first pull rope 17 and the second pull rope 20, the limiting cover 22 and the limiting plates 21 will perform limiting control on the first pull rope 17 and the second pull rope 20 to prevent the oxygen pipe and the endoscope lens body from touching and interfering with the movement of the first pull rope 17 and the second pull rope 20.

[0036] As Figure 1 and Figure 2 shown, a filter cartridge 5 is clamped on the outer side of the mask body 3. A filter screen is arranged at the bottom end of the filter cartridge 5. A connecting pipe 6 is arranged at the top end of the filter cartridge 5. The top end of the connecting pipe 6 is sealed.

[0037] As Figure 1 and Figure 2 shown, a collection cylinder 8 is clamped at the bottom end of the mask body 3. A connecting nozzle 7 is arranged at the top end of the collection cylinder 8. The connecting nozzle 7 is communicated with the connecting pipe 6 through a pipeline. The connection part of the pipeline and the connecting pipe 6 is higher than the connection part of the pipeline and the connecting nozzle 7.

[0038] As Figure 2 and Figure 3 shown, a valve 11 is arranged at the connection part of the collection cylinder 8 and the connecting nozzle 7. The conducting direction of the valve 11 is from the connecting nozzle 7 to the collection cylinder 8.

[0039] As shown Figure 2 in the figure, a groove 9 is formed on the outer side of the collection cylinder 8, and a rubber collar is clamped in the groove 9.

[0040] The air filter cylinder 5 and the collection cylinder 8 can respectively filter the gas exhaled by the patient, and at the same time can collect the foreign objects discharged from the patient's mouth due to stimulation during the examination. A disposable nozzle is connected to the connecting nozzle 7 and connected to the patient's mouth through the nozzle. When the patient exhales, the gas exhaled by the patient will be discharged from the pipeline into the connecting pipe 6 and finally discharged to the outside through the filter screen;

[0041] When foreign objects are discharged from the patient's mouth, since the connection between the pipeline and the connecting pipe 6 is higher than the connection between the pipeline and the connecting nozzle 7, the foreign objects will flow along the inner wall of the connecting nozzle 7 into the collection cylinder 8, and then the collection bag fixed by the groove 9 and the rubber collar at the bottom end of the collection cylinder 8 is used to collect the foreign objects. At the same time, the valve 11 prevents the foreign objects from being sucked back.

[0042] The specific usage method and function of this embodiment:

[0043] In the present invention, the provided sealing assembly can seal the gap between the patient's nasal cavity and the endoscope body and the oxygen tube during the endoscope examination of the patient. At the same time, the mask body 3 is set to be open, directly avoiding the water column condensation that may be caused by the exhaled gas of the patient. When using the mask body 3, first fix the mask body 3 to the patient's face through an elastic drawstring or the like, and align the first connection port 15 and the second connection port 19 with the patient's two nostrils respectively. Then, the oxygen tube and the endoscope body can be respectively inserted into the patient's nasal cavity through the first connection port 15 and the second connection port 19 opened at the top end of the air guide cover 10. While inserting, the rotating arm 24 in the control assembly can be operated through the control button 25. The rotation of the rotating arm 24 will drive the rotating plate 14 to rotate between a group of fixed rings 18, compressing the torsion spring until the two elastic rings 16 penetrated by the free end of the rotating plate 14 respectively cover the outer sides of the oxygen tube and the endoscope body. At this time, the state of the sealing assembly is locked, and then the endoscope body can be controlled through the operation window 4 opened on the outside of the mask. When it is necessary to temporarily fix the endoscope body, the exposed part of the endoscope body can be clamped into the positioning groove 2 opened at the top end of the operation window 4 for temporary positioning.
