Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an inflatable mouthpiece. Background Technology

[0002] Radiotherapy is currently one of the main treatment methods for head and neck tumors. However, during radiotherapy, while killing tumor cells, it inevitably damages the normal tissues surrounding the tumor cells. Oral mucositis caused by radiotherapy is one of the common toxic side effects during radiotherapy for head and neck tumors. According to relevant data, the incidence of oral mucositis in patients undergoing radiotherapy for head and neck tumors is 80%–100%, with a grade III-IV incidence of 74.6%. The mechanism of radiotherapy-induced oral mucositis is still unclear, and no intervention measures have been proven to be consistently effective in preventing and treating oral mucositis. Studies have indicated that the aggravation of oral mucosal damage is closely related to oral microbiota dysbiosis. After radiotherapy, salivary glands are damaged, saliva secretion decreases, the mucosal barrier weakens, and the number of microorganisms related to oral cavity health decreases. Pathogens take advantage of this, regulating the immune evasion and gene expression of microorganisms, thereby enhancing the virulence of the entire microbiota, further reducing the host's immunity, promoting oral ulceration, and leading to the deterioration or aggravation of oral mucositis.

[0003] When conducting randomized, double-blind, controlled studies, the main research contents include the correlation between oral microbiota and radiotherapy dose, the correlation between oral microbiota and radiation-induced oral mucositis, and the prevention and treatment of radiation-induced oral mucositis. It is necessary to administer compound probiotic preparations or perform oral care to the patient's oral cavity. The traditional method of patient self-spraying may lead to incorrect application site and incomplete oral care, which may result in errors in the research results. Summary of the Invention

[0004] In view of the problems that the above-mentioned or existing methods of patient self-spraying medication may lead to incorrect application sites and incomplete oral care, resulting in errors in research results, the present invention is proposed.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1, referring to Figures 1 to 4This is the first embodiment of the present invention, which provides an inflatable mouthpiece device, including a filling component 100, a mouthpiece support plate 101, a base 102 disposed on the mouthpiece support plate 101, wherein the corners of the base 102 can be chamfered to avoid sharp edges of the base 102 from causing damage to the patient's oral cavity, an inflation component 103 disposed on the base 102, and a partition 104 disposed between the mouthpiece support plate 101 and the base 102, the partition 104 being disposed to separate the internal spaces between the mouthpiece support plate 101 and the base 102 and to maintain their respective airtightness; and a shaping component 200, including a suspension shaft 201 disposed on the mouthpiece support plate 101 and a suspension shaft 202 disposed on the suspension shaft 201. The traction component 202 on 01 includes an adjusting component 200 that not only allows for symmetrical adjustment of the mouth support 101, but also allows for individual adjustment on both sides when the user's oral cavity is asymmetrical, making it more suitable for different patients, facilitating clinical use, and improving its applicability; the sealing component 300 includes a modified component 301 disposed within the base 102 and an opening and closing component 302 disposed on the partition 104; and the medication delivery component 400 includes a pressure-sensitive sliding block 401 disposed within the base 102 and multiple spray nozzles 402 disposed on the base 102, wherein probiotic preparations or nursing reagents can be pre-injected into the sealed space formed by the pressure-sensitive sliding block 401 and the base 102 through the spray nozzles 402;

[0029] The suspension shaft 201 is also provided with an external thread, which has a self-locking function and a certain limiting effect, so that the shape of the mouth support plate 101 will not change on its own. The modified component 301 can drive the opening and closing component 302. A thin film is installed on the spray nozzle 402. In addition, the pressure-sensitive sliding block 401 in the base 102 should inject drugs or care agents in advance through the spray nozzle 402 according to the usage needs. At the same time, when the mouth support plate 101 is removed after being used by the patient, it can also be fully coated with saliva in different positions in the patient's cavity. Comprehensive sampling can be carried out by sampling swabs to avoid errors in the test results caused by sampling from a single location.

[0030] Specifically, the mouth support 101 includes a deformable surface 101a and a traction surface 101b. The deformable surface 101a is made of a harmless soft membrane, and the traction surface 101b and the base 102 are both made of harmless rubber. Although most rubber materials will not have a significant impact on patients if a small amount is accidentally ingested, it is still preferable to use harmless rubber materials from a safety perspective.

[0031] The inflation assembly 103 includes an air supply pipe 103a disposed on the base 102 and an inflation ball 103b connected to the air supply pipe 103a; wherein, when the inflation ball 103b is inflated, it can cause the deformable surface 101a to expand, preferably when it fits exactly with the patient's oral cavity, and the traction assembly 202 can deform the traction surface 101b.

[0032] Furthermore, the adjusting component 200 also includes a limiting component 203 disposed on the suspension shaft 201. The limiting component 203 includes an external thread disposed on the suspension shaft 201 and a limiting plate 203a disposed on the suspension shaft 201. The limiting plate 203a can also play a limiting role to prevent the rotating ring 202a from rotating too much and causing it to disengage from the suspension shaft 201. The external thread also has a certain self-locking limiting function, so that when it works with the limiting plate 203a, it can ensure the stable use of the adjusting component 200 and prevent the device parts from disengaging.

[0033] The traction assembly 202 includes a rotating ring 202a threadedly connected to the suspension shaft 201, an anti-locking component 202b on the rotating ring 202a, and a plurality of traction rubber rods 202c fixedly disposed between the anti-locking component 202b and the traction surface 101b.

[0034] Usage: First, depending on the user's needs, probiotic preparations or care reagents should be injected into the sealed space formed by the pressure-sensitive sliding block 401 within the base 102 and the base 102 through the spray nozzle 402. Then, the spray nozzle 402 should be sealed with a film that can rupture under increased air pressure but is not easily damaged under normal conditions. After installation, adjustments are made according to the patient's oral cavity using the adjusting component 200. Rotating the rotating ring 202a on the suspension shaft 201 causes the ring 202a to shift on the suspension shaft. If the patient's oral cavity is standardly symmetrical, both rotating rings 202a should rotate synchronously and to the same degree. If the patient's oral cavity is asymmetrical... Only individual adjustments on both sides are required. During this rotation, the external thread on the suspension shaft 201 acts as a self-locking limiter, and the limiting plate 203a on the suspension shaft 201 also acts as a limiter, preventing the rotating ring 202a from rotating too much and disengaging from the suspension shaft 201. When the rotating ring 202a is rotated, the traction component 202 will cause the traction surface 101b to deform. After adjustment according to the shape of the user's oral cavity, the device needs to be disinfected to minimize the entry of external bacteria into the patient's oral cavity, which could lead to inaccurate bacterial sampling. This avoids possible experimental errors during the sampling process, effectively improves the accuracy of experimental data, and thus improves the precision of research results.

[0035] Subsequently, the patient inserts the device into their mouth and inflates it by squeezing the inflation ball 103b in the inflation component 103. At this time, the other components of the device are in their initial state, i.e., the modified component 301 is in a compressed state, that is, the opening and closing component 302 in the sealing component 300 is in an open state, while the medication application component 400 is in a closed state and is not affected by the inflation process. At this time, only air can be inflated into the mouth support plate 101. When the patient feels that the deformable surface 101a of the mouth support plate 101 is just in contact with their own mouth, the inflation stops. Then, the components in the modified component 301 are removed, so that the mouth support plate 101 is in a closed state and is no longer affected by the inflation operation. The originally sealed space formed by the pressure-sensitive sliding block 401 and the base 102 can now be affected by air pressure. At this time, the inflation operation continues, i.e., the second inflation process begins. Initially, the pressure-sensitive sliding block 401 inside the medication application component 400 moves under air pressure. As air is pumped in, the pressure inside the sealed space formed by the pressure-sensitive sliding block 401 and the base 102 gradually increases until the membrane at the spray nozzle 402 ruptures. At this point, the probiotic preparation or nursing agent inside is sprayed comprehensively into the patient's cavity through the rupture of the membrane. The coverage of the agent is comprehensive, avoiding the incomplete coverage that occurs when the patient manually sprays medication. Subsequently, the device is removed from the patient's mouth. At this point, the outer surface of the deformable surface 101a of the mouth support plate 101 is completely covered with saliva from the patient's mouth. The saliva on the surface is collected using a sampling swab, which allows the collection of bacterial flora from different areas of the patient's mouth. Once the collection is completed, the bacterial flora sampling is finished. The sample is comprehensive at this point, which can effectively improve the accuracy of the research results.

[0036] Example 2, refer to Figures 5-7 This is the second embodiment of the present invention. Unlike the previous embodiment, the modified component 301 includes a ventilation plate 301a disposed in the base 102, a return spring 301b disposed in the ventilation plate 301a, an extension plate 301c disposed on the return spring 301b, a modified adhesive rod 301d disposed on the extension plate 301c, and a driving member 301e disposed on the extension plate 301c. The modified adhesive rod 301d can drive the opening and closing component 302. The modified adhesive rod 301d can change the state of the opening and closing component 302 through its movement trajectory, thereby switching between the functions of shaping and spraying pesticide.

[0037] Specifically, ventilation holes 301a-1 are provided on both the ventilation plate 301a and the extension plate 301c. The ventilation plate 301a is shaped as a horizontal "concave" and the inner diameter of the "concave" is adapted to the extension plate 301c.

[0038] When the return spring 301b is in the maximum compression state, the ventilation holes 301a-1 on the ventilation plate 301a and the extension plate 301c are exactly offset, and the ventilation plate 301a and the extension plate 301c are not airtight. This arrangement ensures that the airtightness of the sealed space formed by the pressure-sensitive sliding block 401 and the base 102 is maintained when the return spring 301b is in the maximum compression state.

[0039] Furthermore, the driving component 301e includes a driving groove 301e-1 disposed on the extension plate 301c, a snap-fit ​​plate 301e-2 disposed on the driving groove 301e-1, a pressure port 301e-3 disposed on the snap-fit ​​plate 301e-2, and a protrusion 301e-4 disposed on the snap-fit ​​plate 301e-2. The driving groove 301e-1 is adapted to the snap-fit ​​plate 301e-2, and a tension membrane is disposed at the pressure port 301e-3 on the snap-fit ​​plate 301e-2. The tension membrane is provided to ensure airtightness.

[0040] Furthermore, the opening and closing component 302 includes a fan-shaped opening 302a disposed on the partition 104, and a fan-shaped cover plate 302b rotatably disposed on the partition 104; the fan-shaped cover plate 302b is larger than the fan-shaped opening 302a, and the fan-shaped cover plate 302b and the modified glue rod 301d are on the same horizontal plane, and the modified glue rod 301d can make the fan-shaped cover plate 302b rotate. It should be noted that a torsion spring is provided at the fan-shaped cover plate 302b, so that it has a reset function.

[0041] The rest of the structure is the same as in Example 1.

[0042] Operation Procedure: Before the second inflation during the above operation, remove the snap-fit ​​plate 301e-2 from the modified component 301, specifically from the extension plate 301c. The procedure for removing the snap-fit ​​plate 301e-2 is as follows: First, press the pressure port 301e-3 on the snap-fit ​​plate 301e-2. At this time, the protrusion 301e-4 on the snap-fit ​​plate 301e-2 will move downwards due to the deformation of the pressure port 301e-3. The snap-fit ​​plate 301e-2 can then be removed from the base 102. After the snap-fit ​​plate 301e-2 is removed, the extension plate 301c will shift under the action of the return spring 301b, causing the modified glue rod 301d to gradually... The device gradually changes from being in a state of compressing the fan-shaped cover plate 302b to being in a state of being detached from the fan-shaped cover plate 302b. At this time, the fan-shaped cover plate 302b is reset under the action of its own torsion spring, so that the fan-shaped cover plate 302b covers the fan-shaped opening 302a. At this time, the opening support plate 101 is kept sealed, and the sealed space formed by the pressure-sensitive sliding block 401 and the modified component 301 is released from the sealed state. Then, the second air injection operation continues, and the spraying operation can then be carried out. The modified component 301 allows the device to switch between different functions by changing the sealing of different parts when different functions are required.

[0043] Example 3, referring to Figures 1-7 This is the third embodiment of the present invention. Unlike the previous embodiment, the anti-locking component 202b includes a groove 202b-1 disposed on the rotating ring 202a, a plurality of balls 202b-2 slidably disposed in the groove 202b-1, and a transition ring 202b-3 connected to the rotating ring 202a through the balls 202b-2.

[0044] Specifically, the transition ring 202b-3 is fixedly connected to the traction rubber rod 202c. The transition ring 202b-3 can rotate within the groove 202b-1. When the rotating ring 202a is rotated, initially the rotating ring 202a will rotate with the transition ring 202b-3. However, after rotating a certain angle, the transition ring 202b-3 will not continue to rotate relative to itself, preventing the traction rubber rod 202c from being twisted and causing abnormal deformation of the mouth support plate 101.

[0045] The rest of the structure is the same as in Example 2.

[0046] Operation Process: During operation, when adjusting the shaping component 200, when rotating the rotating ring 202a, the anti-locking component 202b allows the transition ring 202b-3 to rotate circumferentially within the groove 202b-1 on the rotating ring 202a. After rotating to a certain extent, i.e., after the rotating ring 202a rotates with the transition ring 202b-3 to a certain angle, the transition ring 202b-3 will not continue its circumferential motion relative to itself. Through the setting of the ball bearing 202b-2 and the limiting effect of the traction rubber rod 202c, the rotating ring 202a can prevent the transition ring 202b-3 from over-rotating during rotation, thus avoiding the traction rubber rod 202c from becoming entangled. This is beneficial for the long-term practical use of the device, preventing mechanical jamming and improving its service life.
