Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to an oral applicator suitable for radiotherapy of nasopharyngeal carcinoma patients. Background Technique
[0002] When designing a radiotherapy plan for nasopharyngeal carcinoma radiotherapy, it is often based on the principle of increasing the radiation dose in the target area and minimizing the damage to normal tissues. However, whether it is the preauricular field or the combined face and neck field commonly used in conventional radiotherapy, or the currently commonly used intensity-modulated radiotherapy, it is inevitable to damage the oral mucosa and tissues such as the tongue during irradiation. Moreover, it is very difficult to ensure the repeatability of the tongue position during each radiotherapy setup. To avoid or reduce the damage to local normal tissues, a radiotherapy oral applicator is needed to restrict and protect the tongue.
[0003] Generally, an empty medicine bottle or a modified syringe is held in the mouth to support the oral cavity. The medicine bottle is generally cylindrical, and the contact with the tongue surface is a line contact, so that the contact surface between the medicine bottle and the tongue surface is very small, resulting in the medicine bottle not being able to fix the position of the tongue body well. Moreover, when the medicine bottle or the modified syringe is placed in the oral cavity, the medicine bottle is not ventilated, which is likely to affect the patient's breathing. To solve the above problems, an oral applicator suitable for radiotherapy of nasopharyngeal carcinoma patients is provided. Content of the Utility Model
[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an oral applicator suitable for radiotherapy of nasopharyngeal carcinoma patients.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An oral applicator suitable for radiotherapy of nasopharyngeal carcinoma patients, including a first protective cylinder and a second protective cylinder, the second protective cylinder is sleeved outside the first protective cylinder, a lead rubber is arranged between the first protective cylinder and the second protective cylinder, one end of the second protective cylinder is fixedly connected with a second baffle, a groove is opened at the middle position on the outside of the second baffle, and a protective hole plate is arranged inside the groove.
[0006] Further, a sealing cover is arranged at one end of the first protective cylinder and the second protective cylinder, the outside of the sealing cover is sleeved outside the first protective cylinder, and the inside of the sealing cover is clamped inside the second protective cylinder.
[0007] Further, the sealing cover is made of silica gel material, and chamfers are arranged on both the inner and outer sides of one end of the sealing cover.
[0008] Further, a first baffle is fixedly connected to the position of one end of the first protective cylinder outside the second protective cylinder.
[0009] Further, the first protective cylinder, the first baffle, the second protective cylinder and the second baffle are all made of high molecular polypropylene material.
[0010] Further, the protective orifice plate is connected to the groove through an adhesive layer.
[0011] Advantages of the utility model:
[0012] When the utility model is in use, the mouthpiece applicable to radiotherapy for nasopharyngeal carcinoma patients can protect the tongue through the arranged first protective cylinder, second protective cylinder and lead rubber, avoiding damage during radiotherapy. The arranged first baffle and second baffle can play a role in limiting one end of the first protective cylinder and the second protective cylinder, preventing the first protective cylinder and the second protective cylinder from completely entering the oral cavity. The arranged sealing cover can seal the other end of the first protective cylinder and the second protective cylinder, and can also protect the tongue. The arranged protective orifice plate can block one end of the first protective cylinder, and the holes arranged on the protective orifice plate can leave a breathing passage for the patient.
