One end of the two suction tubes is connected to a suction device, and the other end of the two suction tubes is fixedly connected to a suction pad for suctioning saliva from the patient's mouth.

[0010] Preferably, both the protective plate and the fixator have circular grooves on both sides that match the two suction pads, so that the suction pads can move around in the patient's mouth.

[0011] Preferably, the occlusal mechanism is detachably connected to the inside of the insertion hole via a slot and a buckle, and the retainer is made of soft plastic or other materials to adapt to the tooth shape of different patients.

[0012] Preferably, the absorbent pad has multiple round holes for absorbing saliva.

[0013] This invention provides an endoscope for detecting gastrointestinal bleeding. Compared with the prior art, it has the following advantages:

[0014] (1) The endoscope used for detecting gastrointestinal bleeding inserts a flexible tube into the through hole of the biting mechanism and installs it in the insertion hole of the fixing mechanism. At the same time, the endoscope is secured by wrapping the patient's head with a strap and fixing strap and fastening with Velcro. This achieves the effect of stabilizing and fixing the endoscope tube, preventing the tube from shifting due to the patient's head movement during the examination, and ensuring the smooth progress of the examination.

[0015] (2) The endoscope used for detecting gastrointestinal bleeding has a suction mechanism that is connected to the occlusal mechanism. One end of the suction tube is connected to the suction device, and the other end of the suction tube is used to suction the saliva in the patient's mouth. The suction tube has multiple round holes, which effectively absorbs the saliva, avoids the patient's swallowing reflex, reduces the effect of saliva on oral moisture, prevents the endoscope lens from becoming blurry, and improves the accuracy of doctors' observation of the inside of the digestive tract.

[0022] Embodiment one:

[0023] Please refer to Figures 1 to 4 , a kind of endoscope for detecting digestive tract hemorrhage, including equipment main body 1, equipment main body 1 is respectively fixedly connected with the connector 3 for connecting display screen and the controller 4 for controlling equipment main body 1, and the front end of equipment main body 1 is detachably connected with the hose 2 for inserting into patient digestive tract, hose 2 is sleeved with fixed mechanism 5;

[0024] Fixed mechanism 5 includes guard plate 51 and jack 56 opened in the inside of guard plate 51, the both sides of guard plate 51 are movably connected with bandage 52 and fixed band 54 by fixed shaft 55, to make when pulling bandage 52 drive fixed band 54 to contract, and bandage 52 and fixed band 54 contact surface are fixedly connected with magic tape, to make fixed mechanism 5 be fixed in patient mouth, the inside of jack 56 is detachably connected with occlusion mechanism 6,

[0025] First, occlusion mechanism 6 is inserted into hose 2 by through hole 61, and occlusion mechanism 6 is installed in the jack 56 of fixed mechanism 5, at this time, it is ensured that occlusion mechanism 6 is connected firmly with jack 56, to avoid the situation of loosening or falling off in the process of examination,

[0026] The bandages 52 and the fixing belts 54 of the fixing mechanism 5 are wrapped around the patient's head and fixed by Velcro. During the fixing process, the tightness of the bandages 52 and the fixing belts 54 should be adjusted to ensure that the fixing mechanism 5 can be stably fixed on the patient's mouth and to avoid discomfort caused by over-tightness. At the same time, the air bags 53 on the two bandages 52 can support the patient's head to reduce the discomfort caused by the patient's long-time maintaining the same posture.

[0027] Embodiment Two:

[0028] Please refer to Figures 1 to 4 , the embodiment provides a technical scheme on the basis of the embodiment one: the occlusion mechanism 6 comprises a through hole 61 for inserting the hose 2, the through hole 61 is fixedly connected with a fixer 62, the upper and lower sides of the fixer 62 are provided with occlusion grooves 63 for the patient's teeth to occlude, the bandages 52 on the two sides of the guard plate 51 are fixedly connected with air bags 53 for supporting the patient, the inside of the occlusion mechanism 6 is movably connected with an attraction mechanism 7, the attraction mechanism 7 comprises two attraction pipes 71, one end of the two attraction pipes 71 is connected with an attractor, and the other end of the two attraction pipes 71 is fixedly connected with suction pieces 72 for sucking saliva in the patient's mouth, the two sides of the guard plate 51 and the fixer 62 are provided with circular grooves matched with the two suction pieces 72, so that the suction pieces 72 can move in the patient's mouth, the occlusion mechanism 6 is detachably connected in the inside of the jack 56 through the clamping groove and the buckle for replacement, and the fixer 62 is made of soft plastic or the like to adapt to different tooth shapes of patients, a plurality of circular holes for adsorbing saliva are formed in the suction piece 72. After the fixing mechanism 5 is installed, the patient can occlude the occlusion grooves 63 on the fixer 62 with the teeth, so that the position of the hose 2 is stable and will not be displaced due to the movement of the patient's head or other reasons. During the examination, if saliva is produced in the patient's mouth, the attraction pipes 71 of the attraction mechanism 7 will adsorb the saliva through the circular holes in the suction pieces 72. The design of the suction pieces 72 can move flexibly in the patient's mouth to ensure effective adsorption of the saliva, avoid the patient's swallowing reflex, and avoid too much saliva that may cause the patient's mouth to be wet, so that the lens of the endoscope becomes blurred, affecting the doctor's observation of the inside of the digestive tract, thereby reducing the accuracy of the examination. At the same time, the circular grooves on the two sides of the guard plate 51 and the fixer 62 provide sufficient movement space for the suction pieces 72, so that they can better adapt to the patient's oral movements. The fixer 62 is made of soft plastic or the like and has certain elasticity and adaptability, which can better fit the tooth shapes of different patients and improve the comfort of the patient. The occlusion mechanism 6 is detachably connected in the jack 56 through the clamping groove and the buckle, which facilitates the replacement and cleaning of the occlusion mechanism 6 and ensures that it can be kept clean every time it is used.

[0029] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
