Specifically, the use of words such as "in some embodiments," "exemplarily," and "for example" is intended to present the relevant concepts in a concrete manner, meaning that the specific features, structures, or characteristics described in conjunction with the embodiment may be included in at least one embodiment of this application.
[0027] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0028] Regarding the drawings of this application, it should be clearly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.
[0029] like Figures 1 to 5 As shown, the present application provides an adjustable mouthpiece, including a mouthpiece frame 1 and a tongue depressor 2, the mouthpiece frame 1 and the tongue depressor 2 are injection molded with medical plastic in one step, the mouthpiece frame 1 is provided with a through mounting channel 100 along the axial direction, the mounting channel 100 includes a first port 1001 and a second port 1002, both side walls in the mounting channel 100 are provided with continuous card grooves 101, the tongue depressor 2 includes a tongue depressing portion 200 and elastic card arms 201 arranged on both sides of the tongue depressing portion 200, and a card block 3 is provided on the elastic card arm 201, when the tongue depressor 2 is inserted into the mounting channel 100 from the second port 1002, the two elastic card arms 201 and the card groove 101 form a card connection, and by selecting the card groove 101 in different positions to form a card connection, the length of the tongue depressor 200 extending out of the second port 1002 of the mounting channel 100 can be adjusted.
[0030] With this setting, the tongue depressor length can be flexibly adjusted to suit different patients: the continuous card slot of the installation channel cooperates with the card block of the elastic card arm, and the card position can be selected according to the patient's oral depth and tongue size, and the protruding length of the tongue depressor can be adjusted to solve the problem of poor adaptability of the fixed structure.
[0031] In some embodiments, the card block 3 is adapted to the card slot 101, and the number of the card slots 101 is set according to the adjustment accuracy requirements. Preferably, the card slot 101 includes a first inclined surface 1010, an arcuate surface 1011 and a second inclined surface 1012 connected in sequence, and the slopes of the first inclined surface 1010 and the second inclined surface 1012 are opposite. The first inclined surface 1010 is close to the side of the first port 1001, and its slope is greater than the slope of the second inclined surface 1012. There is also a smooth transition between the second inclined surface 1012 and the first inclined surface 1010 of the two adjacent card slots 101. The card block includes a stop surface 300, an arcuate transition surface 301 and a guide surface 302 that are connected in sequence, and are arranged corresponding to each surface of the card slot. Such an arrangement makes it easier to adjust and remove the tongue depressor 2 toward the second port 1002, and at the same time prevents the adjusted tongue depressor 2 from easily moving toward the first port 1001 due to force.
[0032] It should be understood that the above-mentioned structure of the card block 3 and the card slot 101 is a preferred solution and can also be set to other shapes, and reference can be made to the conventional card connection structure in plastic parts.
[0033] In some embodiments, the two elastic clamping arms 201 are arranged to be spread outward in a direction away from the tongue depressor 200, so that the longer the tongue depressor 2 extends out of the second port 1002, the tighter the connection between the bite frame 1 and the tongue depressor 2 is, ensuring the stability of the tongue depressor 2. When the tongue depressor 2 is inserted from the second port 1002, the two elastic clamping arms 201 need to be squeezed toward the middle and then inserted from the second port 1002 for adjustment.
[0034] In some embodiments, an extension section 2010 is provided on the elastic clamping arm 201 at the rear side of the clamping block 3, that is, the clamping block 3 is not provided at the end of the elastic clamping arm 201, so that the extension section 2010 is convenient for medical staff to operate.
[0035] In some embodiments, a trapezoidal opening 16 is provided on the inner side of the two elastic clamping arms 201, which increases the deformation space, reduces the adjustment force, improves the adjustment convenience, prevents the clamping arms from breaking, and extends the service life.
[0036] In some embodiments, the tongue depressor 200 is bent downward at one end away from the elastic arm 201. The portion of the tongue depressor 200 used to press the tongue is configured in an arc shape, which conforms to the physiological state of the tongue and avoids irritation to the palate. This also increases the contact area and reduces the unit pressure, thereby preventing discomfort and injury to the patient. Furthermore, this prevents the tongue depressor 2 from detaching from the first port 1001.
[0037] In some embodiments, a first convex disc portion 11 is provided on one side of the first port 1001 of the bite frame 1 to enhance the wall thickness of the first port 1001 of the bite frame. The first convex disc portion 11 is used to abut against the outside of the oral cavity when the bite frame 1 is inserted into the oral cavity. The first convex disc portion 11 fits against the facial skin to limit the depth of the bite frame 1 inserted into the oral cavity, while preventing the bite frame 1 from falling completely into the oral cavity and causing harm to the patient.
[0038] The bite frame 1 is provided with a reinforcement ring portion 12 adjacent to the first flange portion 11 , which disperses the stress at the connection between the first flange portion and the bite frame body to prevent the bite frame from breaking due to the patient's biting action during long-term use.
[0039] A second convex disc portion 13 is provided on one side of the second port 1002 of the bite frame 1. The area of the second convex disc portion 13 is smaller than that of the first convex disc portion 11. An annular mounting groove 14 is formed between the first convex disc portion 11 and the second convex disc portion 13. A flexible bite sleeve is provided in the annular mounting groove 14, for example, a flexible bite sleeve made of medical silicone. The small area design of the second convex disc portion 13 reduces the space occupied inside the oral cavity and is suitable for patients with narrow oral cavity; the flexible bite sleeve directly contacts the teeth and gums, buffers the occupant pressure, and prevents the rigid material from wearing the oral tissue.
[0040] The first convex disc portion 11 and the second convex disc portion 13 are both rectangular, and are curved on all sides and corners. The rectangular structure fits the facial contour around the lips, preventing the bite frame from rotating in the mouth and improving positioning stability; the arc treatment eliminates sharp corners, preventing the first convex disc portion 11 from scratching the facial skin and the second convex disc portion 13 from scratching the inner oral mucosa, thereby significantly improving safety of use.
[0041] The two sides of the annular mounting groove 14 are formed into an arc-shaped portion 15 with protrusions at both ends and a depression in the middle. The protrusions at both ends form a clamping effect on the flexible bite sleeve, preventing the flexible bite sleeve from falling off from the two ends of the annular mounting groove 14; the depression in the middle makes the flexible bite sleeve form a slight arc-shaped fit after installation, thereby enhancing the fit between the flexible bite sleeve and the annular mounting groove 14 and avoiding wrinkles on the flexible bite sleeve during use; the smooth arc-shaped transition reduces the stress concentration at the edge of the annular mounting groove 14, further improving the structural strength of the bite frame 1.
[0042] Optionally, the inner protrusion of the flexible bite sleeve is interference-fitted with the arc-shaped portion 15 to prevent the flexible bite sleeve from being displaced significantly.
