Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an oral cavity support device for digestive endoscopy. Background Technology
[0002] Digestive endoscopy is the most direct and effective examination method for diseases of the digestive system, including the esophagus and stomach. It allows direct observation of changes in the structure of the digestive tract wall and pathological changes in the mucosa, playing a crucial role in the diagnosis and treatment of digestive system diseases. During digestive endoscopy, the endoscope and its connecting tube are inserted into the esophagus or stomach through the mouth. To facilitate the examination and prevent the patient from unconsciously biting down on the endoscope tube, an oral support device is required.
[0003] During a digestive endoscopy, the patient's mouth needs to remain open for a long time, which leads to an increase in saliva secretion. Because the patient is in a special position during the examination, they cannot swallow saliva normally. A large amount of saliva accumulates in the mouth, which not only makes the patient feel uncomfortable, but may also cause choking and coughing, interfering with the normal progress of the examination. There is even a risk of saliva being aspirated into the trachea, which can endanger the patient's life in severe cases.
[0004] Currently, there are many shortcomings in the handling of patients' saliva during digestive endoscopy in clinical practice. Some medical staff use manual suction, that is, continuously aspirating saliva with a suction tip in the patient's mouth. However, this method requires continuous operation by medical staff, which consumes a lot of energy. In addition, during the operation, the suction tip is easy to touch the patient's oral mucosa, causing unnecessary damage. In some cases, a kidney dish is placed under the patient's mouth to collect saliva. However, this method can only collect saliva passively and cannot effectively prevent saliva from accumulating in the mouth. It still causes great discomfort to the patient and cannot meet the strict requirements of oral cleanliness for digestive endoscopy, affecting the accuracy and efficiency of the examination. Therefore, a digestive endoscopy oral support device is proposed. Utility Model Content
[0005] In view of this, the present invention provides an oral cavity support device for digestive endoscopy to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.
[0006] The technical solution of this utility model is implemented as follows: a digestive endoscopy oral cavity auxiliary support device includes a silicone sleeve. The outer side wall of the silicone sleeve has a groove. Two absorbent strips are symmetrically fixedly connected to the inner side wall of the groove. There is a gap between the two absorbent strips. Multiple drainage ports are evenly provided on the inner side wall of the groove. A liquid guiding groove is provided inside the silicone sleeve. The drainage ports are connected to the liquid guiding groove. A liquid guiding tube is connected to one side of the silicone sleeve.
[0007] More preferably, the outer wall of the silicone sleeve is provided with a tongue groove.
[0008] More preferably, a support cylinder is fixedly connected to the inner wall of the silicone sleeve.
[0009] More preferably, a baffle is fixedly connected to the outer wall of the silicone sleeve.
[0010] More preferably, two connecting grooves are symmetrically formed on one side of the baffle.
[0011] The present invention has the following advantages due to the adoption of the above technical solution:
[0012] This invention allows the patient's saliva to be absorbed by an absorbent strip, then dispersed into the gap between the two strips. The saliva is then collected in a drainage channel through a drain port and discharged through a drainage tube. This drainage tube can be connected to a liquid delivery pipe to drain the saliva, preventing it from accumulating in the mouth, effectively reducing patient discomfort, minimizing the risk of choking, and making the examination process more comfortable and safe. This significantly improves the patient's examination experience and cooperation.
[0013] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] like Figure 1-3 As shown, this utility model embodiment provides a digestive endoscopy oral cavity support device, including a silicone sleeve 1. The outer side wall of the silicone sleeve 1 has a groove 2. The inner side wall of the groove 2 is symmetrically fixedly connected to two absorbent strips 4. There is a gap between the two absorbent strips 4. The inner side wall of the groove 2 is evenly provided with multiple drainage ports 3. The inside of the silicone sleeve 1 is provided with a liquid guiding groove 5. The drainage ports 3 are connected to the liquid guiding groove 5. One side of the silicone sleeve 1 is connected to a liquid guiding tube 6.
[0022] In one embodiment, a tongue groove 7 is provided on the outer wall of the silicone sleeve 1; the tongue groove 7 restricts the position of the tongue and holds the patient's tongue in place.
[0023] In one embodiment, a support cylinder 8 is fixedly connected to the inner wall of the silicone sleeve 1; the strength of the silicone sleeve 1 is improved by the provision of the support cylinder 8.
[0024] In one embodiment, a baffle 9 is fixedly connected to the outer wall of the silicone sleeve 1; the baffle 9 limits the position of the silicone sleeve 1.
[0025] In one embodiment, two connecting slots 10 are symmetrically provided on one side of the baffle 9; by setting the connecting slots 10, the fixing rope is passed through the connecting slots 10, and the rope fixes the baffle 9 to the patient's head, fixing the position of the silicone sleeve 1 and relieving the pressure of the patient biting and holding the fixed silicone sleeve 1.
[0026] When this invention is in operation: First, the patient bites down on the silicone sleeve 1, which supports the patient's mouth. The fixing rope passes through the connecting groove 10, and the rope fixes the baffle 9 to the patient's head, fixing the position of the silicone sleeve 1 and relieving the pressure of the patient biting down on the silicone sleeve 1. Then, the inside of the patient's mouth is examined through the silicone sleeve 1. The saliva secreted by the patient is absorbed by the absorbent strip 4, and then the saliva in the absorbent strip 4 is dispersed into the gap between the two absorbent strips 4. It is discharged into the liquid guide tank 5 through the drain port 3 for collection, and then discharged through the liquid guide tube 6. The liquid guide tube 6 can be connected to a liquid delivery pipe to discharge the saliva.
[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
