Mouthpiece for painless gastroscopy and colonoscopy

Abstract

This utility model discloses a mouthpiece for painless gastroscopy and colonoscopy, including a lip support structure, a mouthpiece, and an oxygen tube. The lip support structure includes an upper lip baffle and a lower lip baffle connected together, forming an open cavity between them. The mouthpiece is located on one side of the lip support structure and connects to the upper and lower lip baffles, forming an oxygenation chamber that connects to the open cavity. The surface of the mouthpiece has several protrusions. One end of the oxygen tube extends into the oxygenation chamber and connects to the mouthpiece, while the other end passes through the oxygenation chamber and the open cavity, extending to the side of the lower lip baffle opposite to the mouthpiece. The protrusions on the mouthpiece increase the friction between the mouthpiece and the teeth, preventing the mouthpiece from easily detaching from the teeth. The oxygen tube allows for pre-oxygenation and continuous oxygenation during and after the examination, eliminating the need for a nasopharyngeal airway followed by nasal cannula oxygenation, ensuring better blood oxygenation without harming the patient.

Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a mouthpiece for painless gastroscopy and colonoscopy. Background Technology

[0002] Gastroscopy and colonoscopy are endoscopic devices used to examine and treat diseases of the digestive tract (including the esophagus, stomach, and intestines). By inserting a thin, tubular instrument equipped with a camera and light source, it allows real-time observation of the internal condition of the digestive tract, helping doctors diagnose various diseases such as gastritis, gastric ulcers, and intestinal tumors. In addition, gastroscopy and colonoscopy can perform some therapeutic procedures, such as biopsies, hemostasis, and polyp removal. During painless gastroscopy and colonoscopy, a mouthpiece is usually used to keep the mouth open. After the patient falls asleep under painless anesthesia, transient respiratory depression, weak respiratory rate, or tongue retraction can often occur, leading to upper airway obstruction. In severe cases, hypoxemia, shock, and even cardiac arrest may occur. Clinically, nasal cannula oxygenation is commonly used, or a nasopharyngeal airway can be inserted before nasal cannula oxygenation. Nasal cannula oxygenation alone is ineffective for patients with upper airway obstruction. Inserting a nasopharyngeal airway before nasal cannula oxygenation can cause complications such as nasal bleeding and is cumbersome. If the oxygen supply mechanism could be integrated into the bite device, allowing it to both open the mouth and supply oxygen to the patient, the problems associated with nasal cannula oxygenation would be solved, and the bite device would also achieve versatility. Furthermore, current bite devices generally lack structures to enhance bite stability; after anesthesia, patients may not bite firmly, resulting in an unstable bite device that could slip out. Utility Model Content

[0003] This invention provides a mouthpiece for painless gastroscopy and colonoscopy. Its purpose is to solve the problems of existing mouthpieces used for painless gastroscopy, which have only one function: opening the patient's mouth and not being able to supply oxygen to the patient. During painless gastroscopy, nasal cannulas are generally used for nasal oxygen supply, which can easily lead to poor oxygen supply and nasal bleeding. In addition, existing mouthpieces used for painless gastroscopy do not have a structure to enhance the stability of the mouthpiece, so after anesthesia, the patient cannot bite down firmly, the mouthpiece is not stable, and there is a possibility of it slipping out.

[0004] To achieve the above objectives, this utility model provides a mouthpiece for painless gastroscopy and colonoscopy, characterized in that it includes a lip support structure, a mouthpiece, and an oxygen tube. The lip support structure includes an upper lip baffle and a lower lip baffle connected together, forming an opening between the upper lip baffle and the lower lip baffle. The mouthpiece is located on one side of the lip support structure and connects the upper lip baffle and the lower lip baffle. The mouthpiece is ring-shaped, and the ring-shaped mouthpiece surrounds an oxygen-permeable cavity communicating with the opening. The surface of the mouthpiece is provided with several protrusions for increasing the mouthpiece's size. One end of the oxygen tube extends into the oxygen-permeable cavity and connects to the mouthpiece, while the other end passes through the oxygen-permeable cavity and the opening and extends to the side of the lower lip baffle opposite to the mouthpiece.

[0005] In one embodiment, the biting body is elliptical.

[0006] In one embodiment, the outer side of the lower lip baffle is covered with a lower elastic layer, and the outer side of the upper lip baffle is covered with an upper elastic layer.

[0007] In one embodiment, the outer layer of the occlusal body is covered with an occlusal elastic layer.

[0008] In one embodiment, the occlusive elastic layer is made of silicone material.

[0009] In one embodiment, the oxygen tube is detachably connected to the bite body.

[0010] In one embodiment, a retaining ring is provided on the inner wall of the bite body, and a hollow connecting section is provided at one end of the oxygen tube near the bite body, the connecting section being secured within the cavity formed by the retaining ring.

[0011] In one embodiment, an elastic band is provided on the inner wall of the bite body, and the two ends of the elastic band are connected to the bite body. The oxygen tube has a hollow connecting section at one end near the bite body. An annular groove coaxial with the connecting section is formed on the outer wall of the connecting section. The elastic band is sleeved on the outer wall of the connecting section and located in the annular groove.

[0012] In one embodiment, the oxygen tube is directly and fixedly connected to the bite body, and the end of the oxygen tube that is fixedly connected to the bite body is provided with an air hole.

[0013] In one embodiment, the protrusion structure is a protrusion point.

[0014] The above-mentioned solution of this utility model has the following beneficial effects:

[0015] This invention, by incorporating several protruding structures on the occlusal body, increases the friction between the occlusal body and the teeth, preventing the entire occlusal body from easily detaching from the teeth and ensuring its stability within the patient's oral cavity. An oxygen tube is incorporated, with one end connected to the inner wall of the occlusal body and linking to the oxygenation chamber, and the other end extending through the oxygenation chamber and the oral cavity to the outside. The lip support structure and the occlusal body protect the oxygen tube from being bitten by the examiner, ensuring oxygen supply. Once the teeth bite down on the occlusal body, the oxygen tube can provide pre-oxygenation, continuous oxygenation during the examination, and continuous oxygenation during the recovery period. This achieves the multi-functionality of the occlusal appliance, eliminating the need for a nasopharyngeal airway followed by nasal cannula oxygenation. This ensures optimal blood oxygen supply for the patient throughout the examination and recovery period, causing no harm and improving patient safety. Furthermore, the operation is extremely simple.

[0016] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0028] Please see Figures 1 to 6 This invention relates to a painless gastrointestinal endoscopy mouthpiece, comprising a lip support structure 10, a bite body 20, and an oxygen tube 30. The lip support structure 10 includes an upper lip baffle 11 and a lower lip baffle 12 connected to each other. The upper lip baffle 11 supports the upper lip, and the lower lip baffle supports the lower lip, forming an opening 13 between the upper lip baffle 11 and the lower lip baffle 12. The bite body 20 is located on one side of the lip support structure 10 and connects the upper lip baffle 11 and the lower lip baffle 12. The bite body 20 is ring-shaped, and the ring-shaped bite body 20 surrounds an oxygen-permeable cavity 21 that connects to the opening 13. The surface of the bite body 20 is provided with several protrusions 22 for increasing the bite body 20. One end of the oxygen tube 30 extends into the oxygen-permeable cavity 21 and connects to the bite body 20, and the other end passes through the oxygen-permeable cavity 21 and the opening 13 and extends to the side of the lower lip baffle 12 opposite to the bite body 20.

[0029] When placing the bite body 20 into the patient's mouth, first adjust the orientation of the entire bite body 20 so that it faces the mouth. Then, place the upper lip guard 11 and lower lip guard 12 into the mouth, respectively, to abut the upper and lower lips, opening the mouth. Next, have the teeth bite down on the bite body 20. Finally, connect the oxygen tube 30 to an external oxygen concentrator. Alternatively, the oxygen tube 30 can be connected to an external oxygen concentrator before placing the entire bite body into the patient's mouth. Because the bite body 20 has several protruding structures 22, these structures increase the friction between the bite body 20 and the teeth, preventing the bite body 20 from easily detaching from the teeth and ensuring its stability within the patient's mouth. In addition, since the annular occlusal body 20 surrounds an oxygenation cavity 21 that connects to the oral cavity 13, one end of the oxygen tube 30 is fixed to the inner wall of the occlusal body 20 to connect to the oxygenation cavity 21, and the other end passes through the oxygenation cavity 21 and the oral cavity 13 to extend to the outside of the oral cavity to connect to the external oxygen machine. The lip support structure 10 and the occlusal body 20 can protect the oxygen tube 30 from being bitten by the examiner, ensuring the oxygen supply of the oxygen tube 30. Moreover, after the teeth bite the occlusal body 20, the oxygen tube 30 can achieve pre-oxygenation and continuous oxygenation during the examination and the recovery period after the examination. There is no need to choose to implant a nasopharyngeal airway and then use a nasal cannula for oxygenation. This ensures a better blood oxygen supply for the patient throughout the examination and recovery period, without causing harm to the patient, improving the patient's life safety, and the operation is very simple.

[0030] In one embodiment of this application, the occlusal body 20 is elliptical. Of course, the shape of the occlusal body 20 is not limited to this; other shapes suitable for the patient's teeth to bite onto the occlusal body 20 are also applicable to this invention, such as square.

[0031] In one embodiment of this application, the outer side of the lower lip baffle 12 is covered with a lower elastic layer, and the outer side of the upper lip baffle 11 is covered with an upper elastic layer. The provision of the upper and lower elastic layers can increase the comfort of using the upper lip baffle 11 and the lower lip baffle 12. Preferably, the upper and lower elastic layers are made of silicone material.

[0032] In one embodiment of this application, the bite body 20 is fixedly and non-detachably connected to the upper lip baffle 11 and the lower lip baffle 12. In other feasible embodiments, the bite body 20 can be detachably connected to the upper lip baffle 11 and the lower lip baffle 12 to facilitate the replacement of the bite body 20. For example, the bite body 20 can be detachably connected to the upper lip baffle 11 and the lower lip baffle 12 via a snap-fit ​​structure. Further, such as... Figure 2As shown, the snap-fit ​​structure includes a first snap-fit ​​hole 111 on the upper lip baffle 11, a second snap-fit ​​hole 121 on the lower lip baffle 12, a first snap-fit ​​protrusion 23 on the biting body 20 corresponding to the first snap-fit ​​hole 111, and a second snap-fit ​​protrusion 24 on the biting body 20 corresponding to the second snap-fit ​​hole 121. The first snap-fit ​​protrusion 23 and the second snap-fit ​​protrusion 24 are respectively snapped into the first snap-fit ​​hole 111 and the second snap-fit ​​hole 121.

[0033] Optionally, the outer layer of the bite body 20 is covered with an occlusal elastic layer to increase the comfort of using the bite body 20. Preferably, the occlusal elastic layer is made of silicone.

[0034] In one embodiment of this application, the oxygen tubing 30 is detachably connected to the bite body 20. This arrangement facilitates the removal and replacement of the oxygen tubing 30 on the bite body 20. For example, as... Figure 1 As shown, a retaining ring 40 is provided on the inner wall of the bite body 20, and a hollow connecting section 31 is provided at one end of the oxygen tube 30 near the bite body 20. The connecting section 31 is secured within the cavity formed by the retaining ring 40. For example, as... Figure 3 and Figure 4 As shown, an elastic band 50 is provided on the inner wall of the bite body 20. Both ends of the elastic band 50 are connected to the bite body 20. An annular groove 311, coaxial with the connecting section 31, is formed on the outer wall of the connecting section 31. The elastic band 50 is fitted onto the outer wall of the connecting section 31 and located within the annular groove 311. The annular groove 311 prevents the elastic band 50 from easily detaching from the connecting section 31, thus preventing the oxygen tube 30 from easily detaching from the bite body 20. When removing the oxygen tube 30 from the bite body 20, the shape formed by the elastic band 50 is expanded by force, and then the connecting section 31 is removed from the elastic band 50. In other optional embodiments, such as... Figure 5 and Figure 6 As shown, the oxygen tube 30 can also be connected to the bite body 20 in a non-detachable manner, that is, the oxygen tube 30 is directly and fixedly connected to the bite body 20. The end of the oxygen tube 30 that is fixedly connected to the bite body 20 is provided with an air hole 32 for the oxygen in the oxygen tube 30 to be input into the oxygenation chamber 21 to supply oxygen to the patient.

[0035] In one embodiment of this application, the raised structure 22 is a raised dot. In other feasible embodiments, the raised structure 22 may also be a raised strip.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
