A cooling mouth opener for patients with radiation-induced oral mucositis

Abstract

This invention discloses a cooling mouth opener for patients with radiation-induced oral mucositis. This mouth opener aims to address the problem of oral mucositis easily occurring in patients after radiotherapy, affecting masticatory muscles and other related muscles, leading to muscle spasms. The mouth opener includes a fixed box with two rotating shafts rotatably connected to the inner walls of its front and rear sides. Two connecting rods are fixedly connected to the right side of the two rotating shafts. The right sides of the two connecting rods pass through the fixed box and are respectively fixedly connected to an upper mouth opener and a lower mouth opener. Upper and lower occlusal grooves are respectively formed on the opposite sides of the upper and lower mouth openers. Before radiotherapy, the upper and lower mouth openers are placed in the patient's mouth. Then, the patient's mouth is opened by adjusting the mechanism. Because an ice pack is placed inside the storage container, the local temperature of the oral mucosa is lowered. This temperature reduction promotes vasoconstriction, reduces the release of inflammatory mediators, alleviates the inflammatory response, and prevents muscle spasms.

[0002] Oral mucositis is a common oral disease, mainly characterized by inflammation, ulceration, and pain of the oral mucosa. Clinically, the incidence of oral mucositis is high, especially among cancer patients undergoing radiotherapy. Oral mucositis not only causes physical pain but also severely impacts patients' quality of life. Pain and ulcers can lead to difficulty eating, affecting nutrient intake and thus hindering recovery. Furthermore, the inflammation may spread to related muscles such as the masticatory muscles, causing muscle spasms. Therefore, a cooling mouth opener for patients with radiation-induced oral mucositis is proposed. Utility Model Content

[0003] (1) Technical problems to be solved In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cooling mouth opener for patients with radiation-induced oral mucositis. This mouth opener aims to solve the problem that patients are prone to oral mucositis after radiotherapy, which affects the masticatory muscles and other related muscles, causing muscle spasms.

[0004] (2) Technical solution To address the aforementioned technical problems, this utility model provides a cooling mouth opener for patients with radiation-induced oral mucositis. The mouth opener includes a fixed box, with two rotating shafts rotatably connected to the inner walls of the front and rear sides of the fixed box. Two connecting rods are fixedly connected to the right side of the two rotating shafts. The right side of the two connecting rods passes through the fixed box and is fixedly connected to an upper mouth opening sleeve and a lower mouth opening sleeve, respectively. An upper bite groove and a lower bite groove are respectively provided on the opposite sides of the upper and lower mouth opening sleeves. A cooling component is provided between the upper and lower mouth opening sleeves. An adjustment component is provided on the left side of the fixed box to adjust the opening angle of the upper and lower mouth opening sleeves.

[0005] Preferably, both the upper and lower mouth sleeves are arc-shaped structures, and silicone pads are fixedly connected to the inner walls of both the upper and lower bite grooves.

[0006] Furthermore, the cooling component includes a support column fixedly connected to the right side of the fixed box, a storage tank fixedly connected to the right side of the support column, and a cover plate threadedly connected to the right side of the storage tank.

[0007] Furthermore, the outer surface of the storage tank is provided with multiple cooling through holes, and the storage tank is located inside the arc-shaped holes of the upper and lower opening sleeves.

[0008] Furthermore, the adjustment assembly includes a worm gear rotatably connected to the left side of the fixed box via a bearing. A handle is fixedly connected to the left side of the worm gear. Two worm wheels are fixedly connected to the outer surfaces of the two rotating shafts. The other end of the worm gear is located between the two worm wheels and meshes with them.

[0009] Furthermore, elongated holes are provided at both the top and bottom of the right side of the fixed box, and the connecting rod is located inside the elongated holes.

[0010] Furthermore, the connecting rod has a U-shaped structure with a through groove, and the worm gear is located inside the through groove.

[0011] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this utility model, before radiotherapy, an upper and lower mouth opening sleeve are placed in the patient's mouth. Then, by adjusting the components, the upper and lower mouth opening sleeves can be opened, thereby opening the patient's mouth. Since an ice pack is set in the storage tank, the low temperature can be transferred to the oral mucosa through heat conduction, thereby lowering the local temperature of the oral mucosa. This temperature reduction can promote vasoconstriction, reduce blood flow, thereby reducing the release of inflammatory mediators, alleviating the inflammatory response, and avoiding muscle spasms. 2. This utility model utilizes a handle to rotate a worm gear. During rotation, the worm gear, in conjunction with a worm wheel, drives two upper and lower rotating shafts and connecting rods to rotate. The two connecting rods, in turn, cause the upper and lower mouth opening sleeves to open, thereby controlling the mouth opening range. By adjusting the opening angles of the upper and lower mouth opening sleeves, the patient's mouth opening range can be gradually increased, enabling mouth opening training. This strengthens the patient's oral muscle strength and gradually restores joint mobility, thus improving the patient's quality of life. Attached Figure Description

[0019] This specific embodiment is a cooling mouth opener for patients with radiation-induced oral mucositis, and its structural schematic diagram is shown below. Figures 1-6 As shown, the mouth opener includes a fixed box 1. Two rotating shafts 2 are rotatably connected to the inner walls of the front and rear sides of the fixed box 1. Two connecting rods 3 are fixedly connected to the right side of the two rotating shafts 2. The right side of the two connecting rods 3 passes through the fixed box 1 and is fixedly connected to an upper mouth opening sleeve 4 and a lower mouth opening sleeve 5, respectively. An upper occlusal groove 6 and a lower occlusal groove 7 are respectively provided on the opposite sides of the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5. After the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5 are placed in the patient's mouth, the teeth can be located in the upper occlusal groove 6 and the lower occlusal groove 7. A cooling component 8 is provided between the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5. An adjustment component 9 is provided on the left side of the fixed box 1. The adjustment component 9 is used to adjust the opening angle of the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5.

[0020] like Figure 1 , Figure 2 and Figure 5 As shown: In this embodiment, both the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5 are arc-shaped structures, and silicone pads 10 are fixedly connected to the inner walls of the upper bite groove 6 and the lower bite groove 7. The whole is made of medical-grade polymer material, which has good biocompatibility and mechanical strength, and can ensure safety and stability during use. The shape design of the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5 conforms to the characteristics of human oral cavity structure, and can be comfortably placed in the oral cavity. The silicone pads 10 are relatively soft and will not cause additional damage to the oral mucosa, while preventing the mouth opener from sliding in the oral cavity.

[0021] like Figure 2 , Figure 3 and Figure 6 As shown: In this embodiment, the cooling component 8 includes a support column 801 fixedly connected to the right side of the fixed box 1. A storage tank 802 is fixedly connected to the right side of the support column 801, and a cover plate 803 is threadedly connected to the right side of the storage tank 802. This allows the cover plate 803 to be opened, and an ice pack is placed inside the storage tank 802. The ice pack is usually made of environmentally friendly and non-toxic materials and filled with refrigerant. When the ice pack is placed inside the storage tank 802, the low temperature is transferred to the oral mucosa through heat conduction, thereby achieving a cooling effect. The ice pack can be repeatedly frozen and reused.

[0022] like Figure 1 and Figure 2 As shown: In this embodiment, the outer surface of the storage tank 802 is provided with a plurality of cooling through holes 804, and the storage tank 802 is located in the arc-shaped holes of the upper mouth sleeve 4 and the lower mouth sleeve 5; the cooling through holes 804 can better transfer low temperature to the oral mucosa, thereby reducing the temperature of the oral mucosa.

[0023] like Figure 2 and Figure 3 As shown: In this embodiment, the adjustment component 9 includes a worm gear 901 rotatably connected to the left side of the fixed box 1 via a bearing. A handle 902 is fixedly connected to the left side of the worm gear 901. Two worm wheels 903 are fixedly connected to the outer surfaces of the two rotating shafts 2. The other end of the worm gear 901 is located between the two worm wheels 903 and meshes with them. By rotating the handle 902, the handle 902 can drive the worm gear 901 to rotate. During the rotation of the worm gear 901, it cooperates with the worm wheels 903 to drive the upper and lower rotating shafts 2 and the connecting rod 3 to rotate. During the rotation of the two connecting rods 3, the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5 can be opened, thereby controlling the mouth opening range. By adjusting the opening angle of the upper mouth opening sleeve 4 and the lower mouth opening sleeve 5, the patient's mouth opening range can be gradually increased, and mouth opening training can be performed. The patient's oral muscle strength is enhanced, and the joint mobility will gradually recover, thereby improving the patient's quality of life.

[0024] like Figure 1 and Figure 2 As shown: In this embodiment, the upper and lower ends of the right side of the fixed box 1 are provided with elongated holes 11, and the connecting rod 3 is located inside the elongated holes 11; in this way, the connecting rod 3 can move within the elongated holes 11 without affecting the opening and closing of the upper opening sleeve 4 and the lower opening sleeve 5.

[0025] like Figure 4 and Figure 5 As shown: In this embodiment, the connecting rod 3 has a U-shaped structure and a through groove 12, and the worm gear 903 is located inside the through groove 12; this allows the adjusting component 9 to be located in the middle of the fixed box 1, and the force is more evenly distributed.

[0026] Working principle: Before radiotherapy, an ice pack is placed inside the storage tank 802. The upper mouth cover 4 and lower mouth cover 5 are placed in the mouth. Then, the fixing box 1 is pinched and the handle 902 is rotated. During the rotation of the handle 902, the worm gear 901 is rotated. During the rotation of the worm gear 901, it works with the worm wheel 903 to drive the upper and lower rotating shafts 2 and the connecting rod 3 to rotate. During the rotation of the two connecting rods 3, the upper mouth cover 4 and lower mouth cover 5 are opened, thus allowing the patient to open their mouth. Because the storage tank 802 is equipped with an ice pack, the low temperature is transferred to the oral mucosa through heat conduction, thereby lowering the local temperature of the oral mucosa. This temperature reduction can promote vasoconstriction, reduce blood flow, and thus reduce the release of inflammatory mediators and alleviate the inflammatory response. When the handle 902 is rotated in the opposite direction, the upper mouth cover 4 and lower mouth cover 5 move closer to each other, at which point the patient can close their mouth.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
