Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, and more specifically, to a plastic individualized mouthpiece. Background Art
[0002] A mouthpiece is an auxiliary tool used in radiotherapy, especially in the radiotherapy process of head and neck tumors. Its main function is to maximize the protection of normal tissues and reduce radiotherapy-related side effects.
[0003] The setup error of the patient's positioning method with the mouthpiece combined with foam glue is significantly more advantageous than that with single foam glue. The fixation method of the head, neck and shoulder thermoplastic film combined with foam glue + mouthpiece is more conducive to improving the setup accuracy and repeatability of intensity-modulated radiotherapy for head and neck tumors. The mouthpiece has a significant advantage in controlling the lower neck part of the patient compared with the case without wearing the mouthpiece, and is expected to improve the fixation accuracy and repeatability of radiotherapy for head and neck tumors.
[0004] Currently, the mouthpieces used in the market have the following disadvantages:
[0005] 1. The X-ray penetrability of some materials is limited, showing high density under CT, and even forming artifacts, which interfere with the recognition and delineation of normal organs and tumors, and affect the accuracy of radiotherapy;
[0006] 2. Most materials are produced modularly, with limited sizes, poor individualization, and poor fixation effects;
[0007] 3. The prices of a few high-end products are expensive. For example, if made using 3D printing technology, it costs thousands of yuan, increasing the medical burden on patients and the national medical insurance expenditure.
[0008] Based on the above problems, we provide a plastic individualized mouthpiece.
[0009] The above information disclosed in this background art is only used to increase the understanding of the background art of the utility model. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model
[0010] To solve the problems raised in the above background art, the utility model provides a plastic individualized mouthpiece.
[0011] The plastic individualized mouthpiece provided by the utility model adopts the following technical solutions:
[0012] A plastic individualized mouthpiece includes a PU tube; a positioning film, which is preheated and softened and then wound around the outside of the PU tube.
[0013] Preferably, a tongue depressor is further provided at the lower edge of the PU tube.
[0014] Preferably, the positioning film is a thermoplastic film for radiotherapy.
[0015] Preferably, the diameter of the PU tube is 5 mm.
[0016] Preferably, the preheating temperature of the positioning film is 70 °C, and the preheating duration is 15 min.
[0017] Preferably, the outer side of the positioning film is also wrapped with food preservative film.
[0018] Preferably, a ferrule is provided in the middle of the PU tube, and an arc-shaped clamping strip is provided on the side of the tongue depressor. The arc-shaped clamping strip is fully adapted to the PU tube, and the side end of the arc-shaped clamping strip contacts the ferrule.
[0019] Preferably, the ferrule and the PU tube are integrally formed, and the arc-shaped clamping strip and the tongue depressor are integrally formed.
[0020] In summary, the present utility model includes the following beneficial technical effects:

[0030] The following will further elaborate on the present utility model in conjunction with the attached Figures 1 to 6 for a more detailed description.
[0031] It should be noted that the attached drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in their sizes for illustration, and any size is only exemplary and not limiting. In addition, the same reference numerals are used for the same structures, elements or fittings that appear in more than two figures to reflect similar features.
[0032] Embodiment 1
[0033] The embodiment of the present utility model discloses a plastic individualized mouthpiece. Referring to Figures 1 to 4 , a plastic individualized mouthpiece includes a PU tube 1; a positioning film 2, which is wound and wrapped around the outside of the PU tube 1 after being preheated and softened.
[0034] Specifically, a tongue depressor 3 is further provided at the lower edge of the PU tube 1.
[0035] Specifically, the positioning film 2 is a thermoplastic film for radiotherapy.
[0036] Specifically, the diameter of the PU tube 1 is 5 mm.
[0037] Specifically, the preheating temperature of the positioning film 2 is 70 °C, and the preheating duration is 15 min.
[0038] Specifically, the outer side surface of the positioning film 2 is further wrapped with a food preservative film 4.
[0039] First, cut a radiotherapy thermoplastic positioning film of appropriate size and place it in an oven or water tank. Set the temperature to 70°C and heat for 15 minutes to soften it. Then, let the patient open their mouth as wide as possible, straighten their tongue, press it against the lower row of teeth, and use a tongue depressor to press the tongue. Measure the distance between the incisors and the depth (in centimeters) from the leading edge of the lips to the anterior 2 / 3 of the tongue. Next, cut a PU tube 1 of corresponding length (it's better to be a bit longer than shorter), a tongue depressor 3 of corresponding length, and the softened radiotherapy thermoplastic positioning film 2 after heating. Fold it into the corresponding thickness and embed the PU tube 1 in it (to form an oral applicator). At the same time, embed the tongue depressor 3 at the lower edge of the PU tube 1 to enhance the tongue-pressing effect. Cut the front and back side edges of the positioning film 2 to make its length appropriate, and wrap the positioning film 2 tightly with a disposable food plastic wrap 4 to prevent the unformed oral applicator from spreading too much to both sides during biting, which may affect the thickness of the oral applicator at the center and also prevent the edges of the oral applicator from protruding and stabbing the oral mucosa. Instruct the patient to lie flat and bite with appropriate force according to the position during measurement. After 15 minutes, when the positioning film 2 cools and takes shape, there will be tooth marks of the patient on the positioning film 2. Remove the plastic wrap 4 and, if necessary, cut off the protruding part of the PU tube 1. The production is completed.
[0040] In the later stage, during each radiotherapy session, bite the oral applicator according to the tooth marks (rinse the oral applicator with clean water before and after each use and wipe it with alcohol for disinfection).
[0041] It should be noted that: avoid contact with heat sources to prevent the oral applicator from deforming due to heat; each oral applicator is only suitable for one patient during one radiotherapy course.
[0042] For this product, the materials are easily accessible. Radiotherapy departments generally have radiotherapy thermoplastic positioning films and ovens or water tanks, and there is no need to purchase additional relevant materials; the material safety is good. The materials placed in the patient's mouth are non-toxic and do not cause harm to the patient's health; the cost is low. A radiotherapy thermoplastic positioning film only costs a few hundred yuan and can be used by multiple patients, saving medical costs; the production is simple. After training, junior doctors, nurses, and technicians can quickly learn, and one or two medical staff can complete the operation without going out for study, saving human resources; the degree of individuation is high and it can fit patients with different oral sizes and mouth-opening degrees; the comfort is good. The PU tube 1 is unobstructed and does not affect the patient's oral breathing; the fixation and repeatability are good. After being formed, the tooth marks are fixed, and the biting position can be accurately ensured without deviation during each bite, resulting in a small radiotherapy error.
