Description

Technical Field

[0001] This application relates to the field of medical rehabilitation equipment, and more specifically, to an auxiliary rehabilitation device for tumor chemotherapy. Background Technology

[0002] Tumor radiotherapy is one of the methods for treating malignant tumors. It uses radiation to kill cancer cells and shrink or eliminate tumors to treat tumors. Radiation destroys cells in the irradiated area, causing these cells to stop dividing and eventually die. The purpose of radiotherapy is to eliminate tumors to the maximum extent while preserving normal tissue structure and function to the greatest extent possible, thereby prolonging the patient's survival time and improving the patient's quality of life.

[0003] Among them, nasopharyngeal and oral radiotherapy are local treatments of tumor radiotherapy. After radiotherapy, the masticatory muscles and temporomandibular joint become fibrotic, which causes difficulty in opening the mouth, and the natural opening and closing of the mouth cannot reach the state before radiotherapy.

[0004] Currently, for post-oral surgery rehabilitation, patients are generally required to bite on dental splints of varying thicknesses, gradually increasing the thickness. However, biting on the dental splints requires patients to open their mouths voluntarily. For patients who have difficulty opening their mouths voluntarily or can only slightly open their mouths, it is necessary to assist them with oral opening and closing structures. To address this, we propose an auxiliary rehabilitation device for tumor chemotherapy that assists patients in oral opening and closing operations. Summary of the Invention

[0005] The purpose of this application is to provide an oral cavity opening and closing structure to assist patients who have difficulty opening their mouths independently. Compared with existing technologies, it provides an auxiliary rehabilitation device for tumor chemotherapy, including a U-shaped dental splint. Both the upper and lower walls of the U-shaped dental splint are connected to dental support plates. The bottom wall of the dental support plate is connected to the U-shaped dental splint via a connecting band. A downwardly extending fitting pad (first type) is connected to the outer wall of the U-shaped dental splint, and fitting pads (second type) are provided at both ends of the first fitting pad. A hollow cavity is formed inside the U-shaped dental splint. Magnetic pistons are movably connected to both ends of the hollow cavity, and traction ropes are connected to each pair of magnetic pistons. The hollow cavity is close to the center... A pair of contact plates are fixedly connected at the position of the part. The outer ends of a pair of traction ropes pass through the pair of contact plates and then through the U-shaped dental pad and the fitting pad, extending outward. The traction ropes and contact plates are movably connected. A magnetic piston is attached to one end facing the contact plate, and a contact plate that matches the contact plate is attached to it. The contact plate is electrically connected to the contact plate. The inner end wall of the dental support plate near the contact plate is embedded with a magnetic layer that is magnetically repelled by the magnetic piston. Electromagnetic plates are installed at both ends of the inner side of the U-shaped dental pad. Airbags connected to the hollow cavity are connected to both sides of the inner end of the U-shaped dental pad. Multiple infrared lamps are distributed on the inner end wall of the U-shaped dental pad.

[0006] Furthermore, the dental support plate has an occlusal groove at the end away from the U-shaped dental pad, and the width of the occlusal groove gradually decreases from the middle to both sides.

[0007] Furthermore, a pair of guide rods are fixedly connected to the end wall of the end of the dental support piece that fits against the U-shaped dental pad near the middle. The other end of the pair of guide rods passes through the inside of the U-shaped dental pad and is fixedly connected to a limiting plate. The U-shaped dental pad has a perforation for the guide rods to pass through. The pair of dental support pieces move up and down at the outer end of the U-shaped dental pad. When in use, the U-shaped dental pad is embedded in the patient's oral cavity. The U-shaped dental pad is similar in shape to the direction of human teeth. The pair of dental support pieces fit against the upper and lower teeth respectively. By moving the dental support pieces up and down, passive opening and closing of the patient's oral cavity can be achieved.

[0008] Furthermore, the inner end wall of the connecting strip is provided with an adhesive layer that fits into the outer end wall of the U-shaped dental pad, which facilitates disassembly and cleaning.

[0009] Furthermore, the bottom ends of both the first and second occlusal pads extend inward, and cushioning pads are attached to the inner end faces of both the first and second occlusal pads. During use, after the U-shaped dental splint and dental support plate are fitted into the oral cavity, the first occlusal pad fits tightly against the patient's chin, and the second occlusal pad fits tightly against the patient's cheeks, which helps to position the U-shaped dental splint. The cushioning pads on the first and second occlusal pads have a certain thickness, which on the one hand protects the patient's cheeks, and on the other hand prevents the device from falling off when the device assists the patient in opening and closing the mouth, and can accommodate the range of motion of the dental support plate in supporting the upper and lower parts of the mouth.

[0010] Furthermore, the inner ring of the U-shaped dental pad is equipped with wires that are electrically connected to the electromagnetic plate and multiple infrared lamps. The outer ends of the wires pass through the U-shaped dental pad and the fitting pad in sequence and extend outward to connect to an external power supply device.

[0011] Furthermore, the inner end wall of the U-shaped dental pad is connected to a flexible sheath covering the outer end of the infrared lamp and the electromagnetic plate. The outer end of the electromagnetic plate is covered with a flexible sleeve. Both the flexible sheath and the flexible sheath have corner arcs, which protect the patient's oral cavity.

[0012] Furthermore, the airbag is made of elastic material, and the end of the airbag near the electromagnetic plate has an air inlet that communicates with the interior of the hollow cavity.

[0013] Furthermore, a pair of traction ropes extend to the outer end of the U-shaped dental pad and are connected to a traction belt.

[0014] Optionally, the traction belt is made of multiple sections joined together, with a miniature winding device on one of the fitting pads. The miniature winding device is wound with a winding belt, and the other end of the winding belt is fixedly inserted into one end of the traction belt.

[0015] Compared to existing technologies, the advantages of this application are: (1) This scheme adds dental support plates to both the upper and lower ends of the U-shaped dental pad. When in use, the U-shaped dental pad is embedded in the patient's oral cavity. The patient pulls the traction rope outward with his hand. After the traction rope pulls the magnetic piston close to the first contact plate, the pair of dental support plates push outward in the opposite direction to assist the patient in opening his mouth. At the same time, the first contact plate and the second contact plate are electrically connected in contact, and the infrared lamp is activated. The infrared lamp performs infrared laser treatment on the enlarged oral cavity after the mouth is opened. When the electromagnetic plate is activated, the pair of magnetic pistons retract in the opposite direction due to the magnetic adsorption effect of the electromagnetic plate on the magnetic piston. At this time, the pair of dental support plates are reset under the action of oral cavity pressure. At the same time, the infrared lamp is turned off. After the magnetic piston retracts to the electromagnetic plate, the air bag is inflated by the principle of negative pressure. The air bag expands outward, which is conducive to the flexible compression of the patient's oral cheeks. The intermittent opening and closing of the electromagnetic plate is not only conducive to assisting the patient in opening his mouth and performing infrared laser treatment when the mouth is open, but also conducive to exercising the oral cheek muscles and improving the oral rehabilitation effect.

[0016] (2) The bottom ends of the first and the second pair of occlusal pads extend inward, and the inner end faces of the first and the second pair of occlusal pads are attached with cushioning pads. When in use, after the U-shaped dental pad and dental support plate are fitted into the oral cavity, the first occlusal pad is tightly fitted to the patient's chin, and the second pair of occlusal pads are tightly fitted to the patient's cheeks, which is beneficial to the positioning effect of the U-shaped dental pad. The cushioning pads are set on the first and second occlusal pads. The cushioning pads have a certain thickness, which on the one hand protects the patient's cheeks, and on the other hand prevents the device from falling off when the device assists the patient in opening and closing the mouth, and can adapt to the range of motion of the dental support plate supporting the upper and lower parts of the mouth.

[0017] (3) The inner end wall of the U-shaped dental pad is connected to a flexible cladding covering the outer end of the infrared lamp and the electromagnetic plate. The outer end of the electromagnetic plate is covered with a flexible sleeve. Both the flexible cladding and the flexible sleeve have corner arcs, which protect the patient's oral cavity.

[0018] (4) The traction belt is made of multiple sections. One of the fitting pads is equipped with a miniature winding device. The miniature winding device is wrapped with a winding tape. The other end of the winding tape is fixedly inserted into one end of the traction belt. It is designed for patients who have difficulty pulling the traction belt by hand. The traction belt near the end of the traction rope is connected to the winding tape. The miniature winding device connected to the winding tape is installed on the fitting pad. The miniature winding device is made of lightweight material to reduce its weight. The automatic pulling of the winding tape by the miniature winding device replaces manual pulling. It also realizes the work of pulling the traction rope outward to complete the outward support of a pair of dental supports. Attached Figure Description

Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Example

[0022] This application discloses an adjunctive rehabilitation device for tumor chemotherapy. Please refer to [link / reference]. Figure 1-6The device includes a U-shaped dental pad 1, with dental support plates 2 attached to both the upper and lower end walls. The bottom end wall of the dental support plate 2 is connected to the U-shaped dental pad 1 via a connecting band 21. The inner end wall of the connecting band 21 has an adhesive layer that fits against the outer end wall of the U-shaped dental pad 1, facilitating disassembly and cleaning. The end of the dental support plate 2 away from the U-shaped dental pad 1 has an occlusal groove, the width of which gradually decreases from the middle to both sides. A pair of guide rods are fixedly connected to the end wall of the dental support plate 2 near the middle of the end wall that fits against the U-shaped dental pad 1. 22. The other end of a pair of guide rods 22 passes through to the inside of the U-shaped dental pad 1 and is fixedly connected to a limiting plate. The U-shaped dental pad 1 has a perforation for the guide rods 22 to pass through. A pair of dental support plates 2 move up and down at the outer end of the U-shaped dental pad 1. When in use, the U-shaped dental pad 1 is embedded in the patient's oral cavity. The U-shaped dental pad 1 is similar in shape to the direction of human teeth. The pair of dental support plates 2 fit against the upper and lower teeth respectively. The up and down movement of the dental support plates 2 helps the patient to perform oral opening and closing training.

[0023] The outer wall of the U-shaped dental pad 1 is connected to a downwardly extending fitting pad 3, and fitting pads 2 are provided on both the left and right ends of fitting pad 3. The bottom ends of fitting pad 3 and the pair of fitting pads 2 extend inward, and cushioning pads are attached to the inner end faces of fitting pad 3 and the pair of fitting pads 2. When in use, after the U-shaped dental pad 1 and dental support plate 2 are fitted into the oral cavity, fitting pad 3 fits tightly against the patient's chin, and the pair of fitting pads 2 fits tightly against the patient's cheeks, which helps to position the U-shaped dental pad 1. The cushioning pads on fitting pad 3 and fitting pads 2 have a certain thickness, which on the one hand protects the patient's cheeks, and on the other hand prevents the device from falling off when the device assists the patient in opening and closing the mouth, and can adapt to the range of motion of the dental support plate 2 supporting the upper and lower parts of the mouth.

[0024] Please see Figure 2-3The U-shaped dental pad 1 has a hollow cavity inside. Magnetic pistons 5 are movably connected to both ends of the hollow cavity, which are far apart from each other. The outer wall of each magnetic piston 5 has a sealing gasket that seals with the hollow cavity. The sealing gasket has a certain degree of elasticity to better adapt to the bending direction of the hollow cavity. A traction rope 6 is connected to each pair of magnetic pistons 5. A pair of contact plates 7 are fixedly connected near the center of the hollow cavity. The outer ends of the pair of traction ropes 6 pass through the pair of contact plates 7 and then sequentially pass through the U-shaped dental pad 1 and the fitting pad 3, extending outwards. The traction ropes 6 and contact plates 7 are movably connected. The piston 5 has a contact piece 2 8 that matches the contact piece 7 attached to one end of the contact piece 1. The contact piece 2 8 is electrically connected to the contact piece 1. The inner end wall of the tooth support piece 2 near the contact piece 1 is embedded with a magnetic layer that is magnetically repelled by the magnetic piston 5. Electromagnetic plates 10 are installed at both ends of the inner side of the U-shaped tooth pad 1. Airbags 11 connected to the hollow cavity are connected to both sides of the inner end of the U-shaped tooth pad 1. The airbags 11 are made of elastic material. The end of the airbag 11 near the electromagnetic plate 10 is provided with an air inlet that is connected to the inside of the hollow cavity. Multiple infrared lamps 9 are distributed on the inner end wall of the U-shaped tooth pad 1. Please see Figure 4-6 When in use, the U-shaped dental pad 1 is embedded in the patient's mouth. The U-shaped dental pad 1 is similar in shape to the teeth in the human mouth. A pair of dental support plates 2 fit against the upper and lower teeth of the patient's mouth respectively. The patient pulls the traction rope 6 outward with his hand. After the traction rope 6 pulls the magnetic piston 5 closer to the contact plate 7, the pair of dental support plates 2 push outward in the opposite direction. The outward pushing force of the dental support plates 2 helps the patient open his mouth. At the same time, the contact plate 7 and the contact plate 8 are electrically connected, and the infrared lamp 9 is activated and lit. The infrared lamp 9 performs infrared laser treatment on the enlarged oral cavity after the mouth is opened. The reason for choosing to perform infrared laser treatment after the mouth is opened is that the internal space of the oral cavity is larger after the mouth is opened, and the oral muscles will not block the infrared lamp 9, thus improving the laser treatment effect. After the opening has been open for a period of time, when the electromagnetic plate 10 is activated, a time controller is added to this process to preset the opening and closing interval of the electromagnetic plate 10. After the electromagnetic plate 10 is energized, please refer to [the relevant documentation]. Figure 7-8 Relying on the magnetic attraction of the electromagnetic plate 10 to the magnetic piston 5, the pair of magnetic pistons 5 retract in the opposite direction. At this time, the pair of dental support plates 2 are reset under the closing pressure of the oral cavity itself. At the same time, the infrared lamp 9 is turned off. After the magnetic piston 5 retracts to the electromagnetic plate 10, the air in the hollow cavity is squeezed into the airbag 11 by using the principle of negative pressure. The airbag 11 expands outward, which is beneficial for the gentle compression of the patient's cheeks. When the mouth is open, the magnetic piston 5 moves to the outside, and the airbag 11 is in a contracted state. It does not compress the expanded cheeks. By repeatedly and intermittently opening and closing the electromagnetic plate 10, it is beneficial to assist the patient in opening and closing the mouth and to carry out infrared laser treatment in the state of mouth opening and closing. It is also beneficial to exercise the patient's cheek muscles and improve the oral rehabilitation effect.

[0025] The inner ring of the U-shaped dental pad 1 is provided with a wire 12 that is electrically connected to the electromagnetic plate 10 and multiple infrared lamps 9. The outer end of the wire 12 passes through the U-shaped dental pad 1 and the fitting pad 3 in sequence and extends outward to connect to an external power supply device. The inner ring end wall of the U-shaped dental pad 1 is connected to a flexible sheath 13 that covers the outer ends of the infrared lamps 9 and the electromagnetic plate 10. The flexible sheath 13 is made of light-transmitting material. The outer end of the electromagnetic plate 10 is covered with a flexible sleeve. Both the flexible sheath 13 and the flexible sleeve have corner arcs to protect the patient's oral cavity.

[0026] In this embodiment, a pair of traction ropes 6 pass through to the outer end of the U-shaped dental pad 1 and are connected to a traction belt 14. The traction belt 14 is detachable and multi-segmented, so that the length of the traction belt 14 can be set as needed, thereby facilitating the patient to pull the traction belt 14. Example

[0027] The difference between this embodiment and Embodiment 1 is that this embodiment adds a miniature winding device 15 and a winding tape 16 to the structure of Embodiment 1. The rest of the structure remains the same as that of Embodiment 1, as detailed below: Please see Figure 9 The traction belt 14 is made of multiple sections joined together. One of the fitting pads 2 4 is equipped with a miniature retractor 15. A retractor 16 is wound around the miniature retractor 15. The other end of the retractor 16 is fixedly inserted into one end of the traction belt 14. This embodiment is designed for patients who have difficulty pulling the traction belt 14 by hand. The traction belt 14 near the end of the traction rope 6 is connected to the retractor 16. The miniature retractor 15 connected to the retractor 16 is installed on the fitting pad 2 4. The miniature retractor 15 is made of lightweight material to reduce its weight. The automatic pulling of the retractor 16 by the miniature retractor 15 replaces manual pulling. Similarly, the traction rope 6 is pulled outward to complete the outward support of a pair of dental supports 2.

[0028] The above description is merely a preferred embodiment of this application; however, the scope of protection of this application is not limited thereto; any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
