Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary medical instruments for digestive tract inspection, in particular to a mouthpiece for gastroscopy inspection. Background Art

[0002] Gastroscopy is a procedure in which a flexible tube with a camera at the front end is inserted from the mouth into the digestive tract to check whether there are any lesions in the upper digestive tract, such as the esophagus, stomach and duodenum. It is the main means of examining diseases in the upper digestive tract. During the gastroscopy, when the gastroscope passes through the throat into the esophagus, the patient will vomit due to nausea, and the biting action of the upper and lower teeth is very likely to damage the gastroscope. Therefore, a mouthpiece is currently used in medical gastroscopy to assist in the examination.

[0003] The mouthpiece mainly includes a baffle and a support tube. The baffle is fixedly connected to the end of the support tube. When in use, the patient opens his mouth to hold the support tube. The center of the support tube has a channel for the hose with a camera device to pass through. When the patient vomits, the upper and lower teeth will bite on the support tube to prevent the teeth from contacting the hose, thereby effectively preventing the support tube from being bitten. In the actual examination process, the diameter of the support tube of the mouthpiece used for different patients in the same examination room is basically the same, which means that patients with small mouths must also try to open their mouths to accommodate the insertion of the support tube. In particular, in order to prevent the support tube from slipping out of the mouth, a flange is often provided at the end of the support tube, which can prevent the teeth from detaching from the support tube. Since the outer diameter of the flange is larger than the outer diameter of the support tube, the patient needs to try to open his mouth to allow the flange to pass through when holding the support tube in his mouth, which undoubtedly increases the patient's pain and greatly reduces the patient's medical experience.

DETAILED DESCRIPTION

[0021] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a mouthpiece for gastroscopy, comprising an upper support plate 1 and a lower support plate 2 arranged opposite to each other, the upper support plate 1 and the lower support plate 2 are both arc-shaped plate structures and are combined to form a tube-through passage 10, an upper baffle plate 3 is fixedly connected to the upper support plate 1, a lower baffle plate 4 is fixedly connected to the lower support plate 2, an upper movable plate 5 is fixedly connected to the other side of the upper support plate 1 on the upper baffle plate 3, a lower movable plate 6 is fixedly connected to the other side of the lower baffle plate 2 on the lower baffle plate 4, a guide plate 61 is fixedly connected to the lower movable plate 6, the upper movable plate 5 is slidably connected to the guide plate 61 along the up-down direction, a stud 7 is rotatably installed on the lower movable plate 6, and the stud 7 is threadedly connected to the upper movable plate 5. In this embodiment, the upper support plate 1 and the lower support plate 2 are made of polyethylene resin.

[0023] When in use, the medical staff rotates the stud 7. Since the guide plate 6 limits the rotation of the upper movable plate 5, the upper movable plate 5 moves downward under the threaded connection relationship with the stud 7. At this time, the upper support plate 1 moves downward relative to the lower support plate 2 under the drive of the upper movable plate 5. After the upper support plate 1 and the lower support plate 2 are close to each other, the volume of the structure composed of the two is reduced, and the patient can easily put the upper support plate 1 and the lower support plate 2 into the mouth. Then, the medical staff rotates the stud 7 in the opposite direction, so that the upper movable plate 5 moves upward and drives the upper support plate 1 to move. The upper support plate 1 gradually moves away from the lower support plate 2. In this process, the patient's mouth is gradually opened to facilitate the gastroscope to pass through the tube passage 10. It can be seen that the size of the upper part of the bite device for gastroscopy of the utility model for patients can be adjusted according to different patients, ensuring that the patient can smoothly hold the bite device, reducing the patient's pain, and easy to operate.

[0024] As a preferred embodiment, the upper movable plate 5 and the lower movable plate 6 are both arched structures, the upper connecting plates 51 are formed on opposite sides of the upper movable plate 5, and the lower connecting plates 62 are formed on opposite sides of the lower movable plate 6, and the upper connecting plates 51 and the lower connecting plates 62 are parallel to each other. The upper movable plate 5 and the lower movable plate 6 are mutually embraced to form a cavity, which is communicated with the tube passage 10 for the gastroscope to pass through.

[0028] In addition, a screw rod 53 is threadedly connected to the upper connecting piece 51, and the screw rod 53 is located on the side of the upper movable plate 5 away from the stud 7. The lower end of the screw rod 53 passes through the upper connecting piece 51 and abuts against the lower connecting piece 62. When in use, after the patient has the mouthpiece in place, the medical staff rotates the screw rod 53 so that the lower end of the screw rod 53 abuts against the lower connecting piece 62. At this time, the screw rod 53 can lock the relative position between the upper movable plate 5 and the lower movable plate 6, effectively preventing the side of the bite device away from the stud 7 from moving easily. Furthermore, an auxiliary sleeve 54 is fixedly connected to the top of the upper connecting piece 51, and the screw rod 53 is threadedly connected to the auxiliary sleeve 54 and passes through the auxiliary sleeve. The auxiliary sleeve 54 can enhance the connection stability between the screw rod 53 and the upper connecting piece 51, and the use is more reliable.

[0029] In order to facilitate medical staff to rotate the stud 7 and the screw rod 53 , the upper ends of the stud 7 and the screw rod 53 are fixedly connected with a screw piece 71 .

[0030] As a preferred embodiment, flanges 11 are protruding outward at the ends of the upper support plate 1 and the lower support plate 2. The flanges 11 are used to block the upper and lower teeth when the patient bites the upper and lower support plates 1 and 2 to prevent the bite device from falling out of the mouth.
