Description

Technical Field

[0001] This utility model relates to medical supplies, and more particularly to a drool pad for gastroscopy. Background Technology

[0002] With the continuous advancement of medical science and technology, gastroscopy, as the most direct technique for diagnosing and treating upper gastrointestinal diseases, is increasingly widely used in clinical practice. Gastroscopy is, after all, an invasive procedure. To ensure the endoscope passes smoothly through the pharynx and prevent nausea and vomiting caused by throat irritation during insertion, a topical anesthetic—lidocaine gel—is routinely used for pre-operative gargling. The use of anesthetics leads to decreased sensation in the throat, causing temporary pharyngeal dysfunction in patients. Simultaneously, the stimulation of the endoscope tube increases oral secretions; if these secretions accidentally enter the trachea, it can lead to serious adverse reactions such as suffocation. Currently, during gastroscopy, a kidney dish or a surgical drape is placed on the patient's side of the mouth to catch secretions, which often soils the patient's clothing. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the purpose of this utility model is to provide a saliva pad for gastroscopy that is waterproof and stain-resistant, does not soil clothes, bedding, or pillowcases, and keeps them clean at all times.

[0005] To achieve the above objectives, the present invention provides a saliva pad for gastroscopy, comprising a occlusal body and a water-absorbing structure conforming to the curve of the jaw. The edge of the water-absorbing structure is formed with a guide fluid for guiding saliva into the water-absorbing structure. The guide fluid is a flange that protrudes from the curve of the jaw and folds into the oral cavity.

[0006] In the above technical solution, preferably, the water-absorbing structure includes a jaw cover adapted to the jaw curve and a drool sheet mounted on the jaw cover, the drool sheet at least partially covering the jaw cover.

[0007] In the above technical solution, preferably, the jaw shield and the bite body are integrally formed.

[0008] In the above technical solution, preferably, a slot is formed on the occlusal body, and an insert is formed on the mandibular cover. The mandibular cover is inserted into the slot through the insert and fixedly connected to the occlusal body.

[0009] In the above technical solution, preferably, the insert block is interference-fitted with the slot or fixed by screws.

[0010] In the above technical solution, preferably, a buckle is formed on one component of the insert block and the slot, and a slot is formed on the other component. When the insert block is inserted into the slot, the buckle engages with the slot.

[0011] In any of the above technical solutions, preferably, the saliva sheet includes a skin-friendly layer located on the surface of the jaw curve, a diversion layer located in the middle layer, and a waterproof layer located at the bottom layer. The skin-friendly layer is a medical gauze layer interwoven with a surface layer and a base layer.

[0014] In the above technical solution, preferably, three-dimensional protective enclosures are provided on both sides of the effective working area.

[0015] Compared with the prior art, the advantages of the saliva pad for gastroscopy provided by this utility model are:

[0016] The chin guard and absorbent structure conform to the facial contours. The upper skin-friendly layer uses a rolled, absorbent, skin-friendly mesh embossed non-woven fabric that can directly contact the skin, offering excellent permeability and effectively locking in moisture to prevent saliva from flowing behind the ears, seeping into the neck, and onto the shoulder near the examination bed. The upper and surrounding areas use a thickened, skin-friendly non-woven cotton absorbent layer for even better absorption. A flanged edge near the chin guides saliva into the absorbent structure, preventing it from spreading and seeping out. The bottom waterproof layer provides highly effective waterproofing, preventing saliva backflow. Waterproof and stain-resistant, it won't stain clothes, bedding, or pillowcases, keeping them clean at all times. Excess saliva collects within the bib, preventing contamination and cross-infection. It is disposable and can be used immediately after use. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1 to 8 As shown, a saliva pad for gastroscopy according to an embodiment of the present invention includes a biting body 1 and a water-absorbing structure that conforms to the curve of the mandible. The edge of the water-absorbing structure is formed with a guide fluid for guiding saliva into the water-absorbing structure. The guide fluid is a flange 2 that protrudes from the curve of the mandible and folds into the oral cavity.

[0031] In this embodiment, a fluid guide formed by a flange 2 near the jaw guides saliva into the absorbent structure and prevents saliva from spreading and seeping out. The absorbent structure can collect the saliva in the saliva pad, preventing saliva from flowing behind the ear and seeping into the neck and shoulder near the examination bed, avoiding contamination of the sheets. It is also disposable and can be easily discarded to prevent cross-infection.

[0032] In this embodiment, the occlusal body 1 is a hollow structure. Before the gastroscopy, after the occlusal body 1 enters the oral cavity, the patient's teeth bite onto the occlusal body 1, thus keeping the patient's mouth open throughout the examination. The gastroscope enters the oral cavity through the central opening of the occlusal body 1, then passes through the esophagus to reach the stomach tract, thereby performing the gastroscopy. With this embodiment, the patient's oral cavity maintains a safe passage for the gastroscope and catheter during the gastroscopy, ensuring a smooth examination and preventing the patient from closing their mouth due to discomfort, which could affect the gastroscopy or cause injury.

[0033] like Figures 1 to 8 As shown, in the above embodiment, preferably, the absorbent structure includes a jaw shield 31 adapted to the jaw curve and a drool sheet mounted on the jaw shield 31, the drool sheet at least partially covering the jaw shield 31.

[0034] In this embodiment, the flange 2 is formed by folding the edge of the chin guard 31 towards the oral cavity. That is, during the gastroscopy, the flange 2 is folded upward to completely guide the patient's saliva into the saliva sheet for absorption, preventing saliva from flowing down the chin behind the ear or seeping into the neck and shoulder near the examination bed, thus avoiding soiling the sheet.

[0035] In this embodiment, the jaw cover 31 is made of polyolefin resin, which has the property of bending and deforming under external force and can maintain its original shape after the external force is removed. It can also be similarly fused with non-woven fabric materials, thereby ensuring that the jaw cover 31 fits the jaw curve tightly.

[0036] like Figure 2 As shown, in the above embodiment, preferably, the jaw cover 31 and the bite body 1 are integrally formed.

[0037] In this embodiment, the bite body 1 and the mandibular cover 31 are integrally formed, which reduces processing costs and processing difficulty.

[0038] like Figures 3 to 5 As shown, in the above embodiment, preferably, a slot 11 is formed on the bite body 1, and an insert 12 is formed on the mandibular shield 31. The mandibular shield 31 is inserted into the slot 11 through the insert 12 and fixedly connected to the bite body 1.

[0039] In this embodiment, the jaw shield 31 and the bite body 1 are separate structures, both before and after use, and are reassembled during use. This reduces the size of the parts during transportation before and after use.

[0040] like Figures 3 to 5 As shown, in the above embodiment, preferably, the insert 12 is interference-fitted with the slot 11 or fixed by screws.

[0041] In the above embodiment, preferably, a buckle 13 is formed on one component of the insert block 12 and the slot 11, and a slot 14 is formed on the other component. When the insert block 12 is inserted into the slot 11, the buckle 13 engages with the slot 14.

[0042] like Figure 6 As shown, in any of the above embodiments, preferably, the saliva sheet 32 ​​includes a skin-friendly layer 321 located on the curved surface of the jaw, a flow-guiding layer 322 located in the middle layer, and a waterproof layer 323 located at the bottom layer. The skin-friendly layer 321 is a medical gauze layer woven from a surface layer 3211 and a base layer 3212. The surface layer 3211 is chitin fiber, wood pulp fiber, or seaweed fiber, and the base layer 3212 is cotton fiber, polypropylene fiber, or polyester fiber.

[0043] like Figure 8 As shown, in the above embodiment, preferably, the skin-friendly layer 321 includes an effective working area and an edge area; the edge area is connected to the edge of the underlying waterproof layer 323 by adhesive.

[0044] like Figure 8 As shown, in the above embodiment, preferably, an elliptical embossed flow guiding structure 324 is provided in the effective working area of ​​the skin-friendly layer.

[0045] In this embodiment, the elliptical embossed flow-guiding structure has a massaging effect and can also accelerate the flow of liquid to the surrounding area and the flow-guiding layer 322, improving the dryness of the skin-friendly layer.

[0046] The saliva sheet also features a visual usage indicator layer, using color changes or marker lines to indicate when the sheet needs to be replaced.

[0047] like Figure 8 As shown, in the above embodiment, preferably, a three-dimensional protective enclosure 325 is provided on both sides of the effective working area, which can effectively prevent side leakage.
