Abstract

A plastic material seaming device for radiotherapy (hereinafter referred to as seaming device) comprises an upper colloid, a lower colloid and a hollow framework, and is characterized in that: the hollow framework is a hollow short pipe, the upper part and the lower part of the hollow short pipe are respectively provided with a groove, the upper colloid is embedded in the upper groove, and the lower colloid is embedded in the lower groove; the upper and lower colloid are made of plastic which can be softened at 60-80 ℃ and solidified at 40-50 ℃; the hollow framework is made of plastic with the softening temperature higher than the softening temperature of the upper and lower colloids. When in use, the mouth piece is put into hot water with the temperature of 60-80 ℃ to be soaked until the upper and lower colloids are softened, and then the mouth piece is put into the mouth of a patient, the patient bites the upper and lower colloids by the upper and lower rows of incisors respectively, and teeth marks are left on the colloids, and the colloids are cured; after solidification, the tooth marks on the colloid can be meshed with the teeth of a patient, so that the position of the first occlusion is relatively consistent when the patient bites again, and the repeated positioning is realized.

Description

Plastic material mouth piece for radiation therapy

Technical Field

An auxiliary device for radioactive medical treatment.

Background

The radiotherapy of head and neck malignant tumor patients receives high-dose irradiation, the accumulated dose of each part is high, and the total average dose is 6000-7000 cGy. Serious disease symptoms can occur to a plurality of early reaction tissues of the head and the neck, particularly oral ulcer and nerve tissue damage can occur to oral mucosa and peripheral soft tissues due to the accumulation distribution of high dose, patients feel discomfort and have dysphoria, and a plurality of patients can not eat food normally. The nutrient malabsorption to the substances gradually reduces the physique, and influences the treatment effect and the life quality. And the dose of the mandible can be correspondingly increased, the change of the tongue part also can be used for directly protecting and separating the mandible due to unfixed position movement, the existing medical appliance plays a role in protecting the oral cavity, but the repeatability is poor due to the change of the occlusion positions of the upper and lower teeth of the mandible, the dose distribution of radiotherapy is changed, and some patients can not realize oral respiration, so that some dangerous conditions exist in the treatment process. Therefore, there is a need for a new device that can protect the oral cavity well, ensure good repeatability, and enable oral breathing.

Disclosure of Invention

In order to solve the problems that the mouth cavity can be well protected, good repeatability can be ensured, and the mouth cavity breathing can be realized, the invention provides a solution, and a plastic material seaming device (hereinafter referred to as seaming device) for radiotherapy consists of an upper colloid, a lower colloid and a hollow framework, and is characterized in that: the hollow framework is a hollow short pipe, the upper part and the lower part of the hollow short pipe are respectively provided with a groove, the upper colloid is embedded in the upper groove, and the lower colloid is embedded in the lower groove; the upper and lower colloid are made of plastic which can be softened at 60-80 ℃ and solidified at 40-50 ℃; the hollow framework is made of plastic with the softening temperature higher than the softening temperature of the upper and lower colloids. When in use, the mouth piece is put into hot water with the temperature of 60-80 ℃ to be soaked until the upper and lower colloids are softened, and then the mouth piece is put into the mouth of a patient, the patient bites the upper and lower colloids by the upper and lower rows of incisors respectively, and teeth marks are left on the colloids, and the colloids are cured; after solidification, the tooth marks on the colloid can be meshed with the teeth of a patient, so that the position of the first occlusion is relatively consistent when the patient bites again, and the repeated positioning is realized. Because the mouthpiece is hollow, the patient can breathe through the air holes in the mouthpiece; the hollow framework is provided with an up-down direction mark and a label frame; the label frame is used for pasting patient information.

Detailed Description

See fig. 1, 2, 3: the plastic material mouth piece for radiotherapy is shown in figure 1 and is composed of a hollow framework (1), an upper colloid (2) and a lower colloid (3); the hollow framework (1) is a hollow short pipe, the upper part and the lower part of the hollow short pipe are respectively provided with a groove, an upper groove (1.1) and a lower groove (1.2), the upper colloid (2) is embedded in the upper groove (1.1), and the lower colloid (3) is embedded in the lower groove (1.2); the upper and lower colloid are made of plastic which can be softened at 60-80 ℃ and solidified at 40-50 ℃; the hollow framework is made of plastic with the softening temperature higher than the softening temperature of the upper and lower colloids.

See fig. 3, 4, 5: the hollow framework (1) is provided with an upper groove (1.1) and a lower groove (1.2), the bending shape of the hollow framework is similar to the bending shape of upper and lower incisors, and the hollow framework (1) is provided with a hollow air hole (1.3) for the breathing of a patient; one side of the hollow framework (1) is provided with a direction mark (1.4) for distinguishing the upper and lower directions when in use, and the other side of the hollow framework (1) is provided with a label frame (1.5) for pasting patient information.

When in use, the mouth piece is put into hot water with the temperature of 60-80 ℃ to be soaked until the upper and lower colloids are softened, and then the mouth piece is put into the mouth of a patient, the patient bites the upper and lower colloids by the upper and lower rows of incisors respectively, and teeth marks are left on the colloids, and the colloids are cured; after solidification, because tooth marks are left on the colloid and can be meshed with teeth of a patient, the position of the colloid is relatively consistent with that of the colloid in the first occlusion during the second occlusion, and the colloid can be repeatedly positioned. Because the mouthpiece is hollow, the patient can breathe through the air holes in the mouthpiece.

See fig. 2, 6: in the mouth piece, an occlusal surface included angle (4) is formed between the upper colloid (2) on the hollow framework (1) and the surface of the lower colloid (3) so that a patient can be occluded more comfortably.

The upper rubber body (2) and the lower rubber body (3) of the mouth piece can also be made of other materials which can be quickly solidified at normal temperature.
