DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] Embodiment 1: refer to Figures 1-3The utility model provides a digestive tract intubation protection device, including the mounting plate 1, the middle position of mounting plate 1 is equipped with the through hole 2, the through hole 2 is connected with the catheter 3, both sides of mounting plate 1 are rotatably connected with the toothed plate 4, and one end of every toothed plate 4 is sleeved with rubber sleeve 5, and every rubber sleeve 5 is connected with the thickened pad 6, and rubber sleeve 5 and thickened pad 6 are integral structure, and the opposite side of two toothed plates 4 is fixedly connected with the limiting frame 7, and every limiting frame 7 is fixedly connected with the first spring 8, and one end of every first spring 8 is fixedly connected to mounting plate 1.

[0022] Working process:

[0023] Firstly, the patient's mouth is opened, and the two toothed plates 4 are oppositely rotated, so that the distance between the two toothed plates 4 is reduced. Then, the two toothed plates 4 are inserted into the patient's mouth. The two toothed plates 4 are in contact with the upper and lower jaws of the patient through the rubber sleeves 5. The thickened pads 6 are located between the teeth and the rubber sleeves 5 to prevent the teeth from biting through the rubber sleeves 5. When the upper and lower jaws squeeze the two toothed plates 4, the toothed plates 4 squeeze the first springs 8. After the first springs 8 are compressed, they generate a restoring force. At the same time, after the toothed plates 4 are rotated, the limiting frames 7 are also rotated. After the two limiting frames 7 are in contact, they limit the rotation angle of the toothed plates 4. The intubation tube passes through the catheter 3 and the through hole 2 in sequence. The intubation tube passes through the gap between the two limiting frames 7. After the toothed plates 4 are rotated, they will not come into contact with the intubation tube under the rotation of the limiting frames 7, so as not to squeeze the intubation tube, thereby not affecting the examination of the digestive tract.

[0024] In example 1, after the intubation tube passes through the through hole 2, the intubation tube is prone to sliding on the catheter 3 due to the lack of fixation. Referring to Figure 4 As another preferred embodiment of the utility model, the difference from example 1 is that the mounting plate 1 is connected with an anti-skid mechanism 9. The anti-skid mechanism 9 includes a fixed plate 91 rotatably connected to the mounting plate 1. The fixed plate 91 is fixedly connected with a second spring 92. One end of the second spring 92 is fixedly connected to the upper end of the catheter 3. The fixed plate 91 is fixedly connected with a connecting rod 93. One end of the connecting rod 93 is fixedly connected with a squeezing ball 94. The bottom end of the squeezing ball 94 is provided with an arc-shaped slot. The upper end of the catheter 3 is provided with a slot hole 95. The squeezing ball 94 can pass through the slot hole 95. When the intubation tube passes through the catheter 3, the squeezing ball 94 is moved upward. The squeezing ball 94 drives the connecting rod 93 to rotate. The connecting rod 93 drives the fixed plate 91 to rotate. After the fixed plate 91 is rotated, the second spring 92 is pulled. After the second spring 92 is pulled, it generates a restoring force. After the movement of the intubation tube is completed, the squeezing ball 94 is released. Under the action of the restoring force of the second spring 92, the fixed plate 91 is driven to rotate downward. The fixed plate 91 drives the squeezing ball 94 to rotate through the connecting rod 93. The squeezing ball 94 passes through the slot hole 95. The bottom end of the squeezing ball 94 is in contact with the intubation tube through the arc-shaped slot, so as to squeeze and fix the intubation tube, thereby preventing the intubation tube from sliding.

[0025] In the embodiment 1, when the cannula is protected, saliva in the mouth is easy to flow out from one end of the catheter 3 through the through hole 2, and the saliva will drop to the ground, refer to Figure 4 As another preferred embodiment of the utility model, the difference from the embodiment 1 is that the one end of the catheter 3 is sleeved with the anti-dripping mechanism 10, the anti-dripping mechanism 10 includes the fixed ring 101, the fixed ring 101 is sleeved to the one end of the catheter 3, the inner ring wall of the fixed ring 101 is provided with the clamping groove, the adsorption ring 102 is clamped on the clamping groove, the adsorption ring 102 is the sponge ring, the fixed ring 101 fixes the adsorption ring 102, the adsorption ring 102 contacts the cannula, and the adsorption ring 102 seals the gap between the cannula and the catheter 3, so that saliva is prevented from flowing out from the one end of the catheter 3.

[0026] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art in the technical range disclosed by the utility model, according to the technical scheme and the utility model concept of the utility model, equivalent replacement or change are covered in the protection scope of the utility model.
