Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bite plate that can prevent airway obstruction. Background Technology

[0002] During gastroscopy, the bite block provides space for insertion of the endoscope and prevents the patient from biting and damaging the endoscope tube. After anesthesia for painless gastroscopy, the patient's muscles relax, making it easy for the tongue to fall back and obstruct the airway, especially in obese patients. Clinically, a tongue depressor is used to prevent this. Combining the bite block and tongue depressor into an integrated device facilitates clinical use.

[0003] Chinese patent application CN209203217U discloses a tongue depressor assembly for painless gastroscopy and painless bronchoscopy, offering various angle and depth adjustment functions. However, achieving these functions requires a highly complex design. It necessitates an adjustment section on the tongue depressor, equipped with depth adjustment holes and angle adjustment latches, and an adjustment component on the tongue depressor plate, featuring spring clips and locking hooks. The adjustment section is too close to the tongue depressor, requiring full adjustment before insertion into the patient's mouth during clinical use. Adjustment during gastroscopy may touch the patient's mouth, causing discomfort and affecting the examination. Furthermore, the shared internal channel of the tongue depressor and endoscope tube can interfere with each other and obstruct the doctor's view. Summary of the Invention

[0004] 1. The problem to be solved

[0005] To address the problems in existing technologies, such as complex design of the adjustment section, excessive proximity to the bite, and sharing of the internal channel of the bite with the endoscope tube, this application provides a bite that can prevent airway obstruction. Its adjustment section has a simple design, is far from the bite, and the support plate forms another channel outside the bite to accommodate the tongue depressor, thus avoiding interference with the endoscope tube.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0040] Example 1

[0041] According to the appendix Figure 1-4 As shown in the figure, this utility model embodiment discloses a mouthpiece that can prevent airway obstruction, including a mouthpiece body 1, a mouthpiece outer extension plate 2, a tongue depressor baffle 3, and a tongue depressor body 4.

[0042] The tongue depressor body 1 includes an intraoral tube 11, an inner tongue depressor baffle 12 and an outer tongue depressor baffle 13 respectively disposed on both sides of the intraoral tube 11, and a support plate 14 connecting the inner tongue depressor baffle 12 and the outer tongue depressor baffle 13. The thickness of the inner tongue depressor baffle 12 and the outer tongue depressor baffle 13 is 1 mm. An elongated hole 121 is opened on the inner tongue depressor baffle 12, and a hole 132 is opened on the outer tongue depressor baffle 13 for inserting the tongue depressor body 4. The connection between the support plate 14 and the outer tongue depressor baffle 13 is located below the hole 132, providing sufficient adjustment space for the tongue depressor body 4. In use, the patient bites the upper end of the intraoral tube 11 with their upper teeth and bites the support plate 14 with their lower teeth. The inner tongue depressor baffle 12 is fixed inside the teeth to prevent the tongue depressor body 1 from falling out, and the outer tongue depressor baffle 13 fits and limits its position against the outside of the patient's mouth.

[0043] The outer extension plate 2 of the bite is disposed on the outer baffle 13 of the bite and is used to support the tongue depressor baffle 3. The outer extension plate 2 of the bite is flush with the plane of the lower end of the inner end of the inner tube 11.

[0044] The tongue depressor baffle 3 is located at the outer end of the outer extension plate 2 of the bite, and is arranged perpendicularly to the outer extension plate 2 of the bite. The bite body 1, the outer extension plate 2 of the bite, and the tongue depressor baffle 3 are integrally formed. The tongue depressor baffle 3 has a total of 9 slots 31 on the side facing the bite body 1. The tongue depressor baffle 3 is used to engage and limit the tongue depressor body 4, and the slots 31 are used to adjust the angle of the tongue depressor body 4.

[0045] The tongue depressor body 4 is a plate-like structure with interconnected arc-shaped and straight plate sections. A first protrusion 41 is located on the back of the middle section of the tongue depressor body 4, abutting against the elongated hole 121 to limit the tongue depressor body 4 and prevent it from being inserted too deeply into the oral cavity. A second protrusion 42 is located on the front of the front end of the tongue depressor body 4, while the back is smooth and presses against the tongue. The design of the first protrusion 41 and the second protrusion 42 limits the adjustment range of the tongue depressor body 4, preventing it from detaching from the bite block body 1.

[0046] The back of the tongue depressor body 4 has an adjustment protrusion 43, which facilitates the adjustment of the position of the tongue depressor body 4. In use, the tongue depressor body 4 can be pushed into the oral cavity to a depth of 85mm. The rear end is movably engaged in one of the limiting slots 31 of the tongue depressor baffle 3. Engaging the rear end of the tongue depressor body 4 in different slots 31 allows for adjustment of the insertion angle and depth. The tongue depressor body 4 can be adjusted and fixed by the cooperation of the first protrusion 41 with the elongated hole 121 and the cooperation of the adjustment protrusion 43 and the limiting slot 31. A certain amount of space is left above the slot 31 to the outer extension plate 2 of the bite, allowing the tongue depressor body 4 to bend. The back of the arc-shaped section of the tongue depressor body 4 contacts the patient's tongue, thus enabling tongue depression and preventing the tongue from falling back. Therefore, the angle adjustment space of the tongue depressor body 4 is independent of the endoscope insertion space of the bite body 1, and the angle adjustment of the tongue depressor body 4 does not affect the entry and operation of the endoscope. Furthermore, the design of multiple slots 31 allows the tongue depressor body 4 to be adjusted at an angle according to the patient's condition. When not in use, the tongue depressor body 4 can be removed from the patient's mouth, at which point the second protrusion 42 abuts against the elongated hole 121.

[0047] Furthermore, the outer baffle 13 of the bite is also provided with two symmetrically arranged straps 131. Initially, the patient takes the intraoral tube 11 into their mouth and bites down, thus fixing the intraoral tube 11 inside the oral cavity, while the outer side is secured to the head by the two straps 131. Preferably, one strap 131 has a hook side for Velcro, and the other strap 131 has a fleece side for Velcro. The combination of the hook and fleece sides allows for the connection and fixation of the two straps 131, as well as adaptation to different head circumferences.

[0048] After anesthesia for gastroscopy, when using the device described in this application, the tongue depressor body 4 is pushed into the oral cavity, and the back of the arc-shaped section slides towards the esophagus to contact the patient's tongue and presses downward to open the patient's airway. The engagement angle between the rear end of the tongue depressor body 4 and the tongue depressor baffle 3 is then adjusted according to the patient's condition. After the patient's gastroscopy, the tongue depressor body 4 is removed by adjusting the protrusion 43 until the second protrusion 42 abuts against the elongated hole 121 to prevent discomfort after the patient awakens.

[0049] The tongue depressor body 1, the outer extension plate 2, and the tongue depressor baffle 3 are made of high-density polyethylene resin, molded as a single piece, and have a certain degree of elasticity. The tongue depressor body 4 is also made of high-density polyethylene resin. During assembly, press down parallel to both ends of the elongated hole 121 to enlarge its opening. Then, pass the front end of the tongue depressor body 4 through the hole 132 and the elongated hole 121 in sequence. Because the opening of the elongated hole 121 is enlarged, the second protrusion 42 can pass through. During use, the patient bites down and applies pressure in the vertical direction of the elongated hole 121, which only narrows the opening of the elongated hole 121. There is no need to worry about the tongue depressor body 4 falling out.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
