Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bronchoscope mouthpiece, and particularly relates to an adjustable bronchoscope mouthpiece. BACKGROUND

[0002] Bronchoscopy is one of the important means for diagnosis and treatment of respiratory diseases. During bronchoscopy, a mouthpiece is an essential auxiliary instrument, which can protect the bronchoscope and the patient's oral cavity and maintain a stable operating channel, prevent the patient from biting and damaging the bronchoscope or guide wire due to discomfort or unconsciousness, and avoid direct friction between the patient's teeth and the bronchoscope, reducing the risk of mirror body scratches. It can also fix the oral opening degree to ensure smooth entry of the bronchoscope into the airway and reduce the difficulty of intubation caused by the patient's oral closure or deviation.

[0003] However, the bronchoscope mouthpiece in the prior art still has some shortcomings in actual use. First, the existing mouthpiece is mostly a hard plastic structure formed in one piece, with a fixed opening size that cannot be adjusted according to the patient's opening degree. Even if some mouthpieces are equipped with an adjustment structure, they use rigid structures such as lead screws for adjustment, which is relatively cumbersome to operate, and the production cost is high. Moreover, such mouthpieces lack elastic buffer design, and long-term biting can cause toothache and mandibular joint fatigue, causing the patient to unconsciously bite tightly or twist his head due to discomfort, causing the bronchoscope to deviate and increasing the risk of operation. Second, some patients may have increased salivation during bronchoscopy due to fear or discomfort caused by wearing the mouthpiece, which can interfere with the stability of the mirror body and cause frequent swallowing of saliva. Therefore, the present application provides an adjustable bronchoscope mouthpiece to meet the needs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide an adjustable bronchoscope mouthpiece to solve the problem of existing mouthpieces that are cumbersome to adjust during bronchoscopy, have poor wearing comfort, and cause patients to frequently swallow saliva, which interferes with bronchoscopy.

[0005] To solve the above technical problems, the present application provides the following technical solutions: The adjustable bronchoscope mouthpiece comprises an upper plate body and a lower plate body, the upper plate body and the lower plate body are fixedly connected through a circular connecting frame, and the upper plate body and the lower plate body are symmetrically arranged on the outside of the connecting frame; the outside of the upper plate body and the lower plate body is fixedly connected with a tooth occlusion area, a recess for accommodating teeth is formed in the inner side of the tooth occlusion area, a weakening groove is formed in the inner side of one end of the upper plate body and the lower plate body close to the connecting frame, an adjusting assembly is arranged between the upper plate body and the lower plate body, and a suction assembly is arranged on the outer side of the lower plate body; the adjusting assembly is used for adjusting the opening degree between the upper plate body and the lower plate body, and the adjusting assembly is connected between the upper plate body and the lower plate body; the suction assembly is used for sucking saliva accumulated in the oral cavity of a patient, and the suction assembly is connected with the adjusting assembly.

[0007] Optionally, a lower air bag is sleeved in the lower fixed seat, and an upper air bag is sleeved in the upper fixed seat; the outside of the upper air bag and the lower air bag is provided with a corrugated deformation area; the end of the corrugated deformation area is fixedly connected with a positioning plate through a connecting end; and the corrugated deformation area has a bellows structure.

[0008] Optionally, the upper air bags are connected in communication through first communication pipes, the lower air bags are connected in communication through fourth communication pipes, the upper air bags and the lower air bags corresponding in position are connected in communication through second communication pipes, the outside of the fourth communication pipe is fixedly connected with a first connecting pipe, and the first connecting pipe is detachably connected with the inflation pump through a joint.

[0009] Optionally, the suction assembly comprises a through opening formed in the outer side of the lower fixed seat, the outside of the lower air bag is provided with a side edge expansion area matched with the shape of the through opening, and the side edge expansion area extends to the outer side of the lower fixed seat through the through opening and is fixedly connected with a suction seat.

[0010] Optionally, the outside of the suction seat is provided with a suction area located on the outer side of the lower plate body, the suction seat and the suction area are both hollow structures, and the two are in communication with each other.

[0011] Optionally, the outside of the suction area is provided with uniformly distributed gap grooves, the inner side of the gap grooves is provided with suction holes in communication with the inside of the suction area, the gap grooves have a hook shape matched with the shape of the outside of the suction area, and the suction holes are uniformly distributed in the gap grooves.

[0012] Optionally, the suction seats are connected in communication through third communication pipes, the outside of the third communication pipe is fixedly connected with a second connecting pipe, the end of the second connecting pipe is sleeved with a joint, and the second connecting pipe is detachably connected with the suction pump through the joint.

[0013] Compared with the prior art, the present application has at least the following advantages: In the above scheme, by setting the adjusting assembly, the lower fixing seat, the upper fixing seat, the positioning plate, the upper air bag and the lower air bag jointly expand the upper plate body and the lower plate body from the inner side of the upper plate body and the lower plate body, keep the mouth opening device in the expanded state in the patient's oral cavity, and can quickly and finely adjust the opening degree of the upper plate body and the lower plate body, which can effectively support the patient's oral cavity and ensure the normal performance of bronchoscopy, and will not excessively press the inner wall of the oral cavity, thereby reducing the discomfort of the patient.

[0016] By setting the suction assembly, a negative pressure can be generated in the suction area inside the channel formed by the second connecting pipe, the third communicating pipe and the suction seat during the bronchoscopy, so that the suction area can suck the saliva secreted and accumulated in the patient's oral cavity through the suction hole, thereby effectively avoiding the frequent swallowing of saliva by the patient to interfere with the stability of the bronchoscope.

[0017] By setting the side edge expansion area and the gap groove in the suction assembly, the side edge expansion area on the lower air bag also expands synchronously during the inflation adjustment process by the inflation pump, and the suction seat is displaced outside the lower fixing seat, so that the accuracy of the saliva suction position is ensured, and the gap groove is provided to retain the gap between the suction hole and the patient's oral cavity, thereby avoiding the suction hole being blocked and unable to suck the saliva secreted in the patient's oral cavity, and further improving the scheme of the mouth opening device.
