Description
TECHNICAL FIELD

The present invention relates to scattered ray-shielding underwear for radiation therapy, and more particularly, to scattered ray-shielding underwear for radiation therapy which shields scattered rays and braking radiation generated due to high-energy radiation during radiation therapy and thus prevents unnecessary exposure of a patient thereto so as to prevent cancer.


BACKGROUND ART

Early diagnosis through medical examination enables early diagnosis of tumors, and increases the number of patients who undergo both surgical operation and chemotherapy or radiation therapy together. A large proportion of cancer patients undergoes radiation therapy due to increase in target objects of radiation therapy and development of radiation therapy equipment. In radiation therapy, normal tissues should be irradiated with the minimum amount of radiation, and a high-energy dose of radiation should be concentrated on tumors so as to increase treatment effect.


An important factor which should be considered in use of high-energy radiation during radiation therapy is the amount of a surface dose exposed to a patient together with a prescription dose to a tumor. Because, during radiation therapy, even a low radiation dose may cause a stochastic disorder of a patient and may shorten the lifespan of the patient, in order to achieve justification of radiation, exposure of parts of the patient's body other than a radiation therapy site to radiation should be reduced as much as possible extent.


Scattered rays generated by a medical linear accelerator are caused by an aperture, a filter, air, a subject, etc. Radiation emitted by a radiation source is scattered by surrounding substances, and then reaches a patient. Even a low radiation dose to the surroundings except for an irradiation surface compared to an irradiation surface radiation dose causes increase in a stochastic influence on the patient.


That is, scattered rays generated during radiation therapy may cause secondary radiation exposure of other organs and tissues than a target part for treatment. Recently, shielding tools used to reduce radiation exposure are mainly used to protect hospital workers from radiation. Further, there is a lack of protection of patients from radiation.


With regard to this, Korean Patent Registration No. 1967664 (referred to hereinafter as ‘Related Art Document’) discloses a protector for medical imaging. The protector for medical imaging of Related Art Document includes a shielding unit including a contrast material and a gap maintenance member attached to the bottom surface of the shielding unit and configured to space the shielding unit apart from a body part by a designated gap, and the thickness of the gap maintenance member is 10 to 40 mm.


The protector for medical imaging of Related Art Document is advantageous in that it may effectively protect a patient's specific body part having a high radiation sensitivity, such as the breast, thyroid gland, crystalline lens, or genital gland of a woman, during medical imaging, such as computed tomography (CT) scan, general X-ray examination, or fluoroscopy, using the shielding unit including the contrast material which may shield radiation.


The shielding unit may be manufactured to be deformable depending on patient's body curvature, and may be deformed into various shapes. Further, an adhesive unit, such as an adhesive tape, is provided on the bottom surface of the gap maintenance member, and thus, the gap maintenance member is fixed to the skin. However, as the deformation amount of an elastic material increases, the elastic recovery of the elastic material increases. Further, there is a certain limit to the adhesiveness of the adhesive tape. Therefore, when the shielding unit is deformed so as to fit with a protruding part, such as the breast of a woman, the part of the shielding unit attached to the protruding part is easily detached from the protruding part due to the elastic recovery of the material.


Various types of radiation, such as high-energy photon beams, electron beams, proton beams, and heavy ion beams, are used in radiation therapy. Further, properties of scattered rays are varied depending on the type of radiation. Therefore, the scattered rays may be effectively shielded using a different shield depending on the type of radiation.


Braking radiation is electromagnetic radiation produced by deceleration of charged particles, such as electrons, when the charged particles are deflected by other charged particles, such as atomic nuclei. When an atomic nucleus attracts and deflects a beta (β-) ray and thus an acceleration is changed, photons with energy equal to an energy difference due to the change in the acceleration of the beta (β-) ray are released.


Negatively charged (−1) beta (β-) rays are attracted by positively charged (+) atomic nuclei. That is, the beta rays are deflected toward the atomic nuclei, and kinetic energy is reduced. As a result, braking radiation is emitted equal to an energy difference.


When substances having high atomic numbers, such as lead (82Pb), tungsten (74W), bismuth (83Bi), barium (56Ba), cadmium (48Cd), tin (50Sn), and bismuth alloys (bismuth, cadmium, tin, lead, and indium), are used as high-energy radiation shields, the degree of deflection of the beta rays is increased, and thus, probability of occurrence of braking radiation is raised. However, the protector for medical imaging of Related Art Document is not capable of preventing exposure to braking radiation, when a substance having a high atomic number is used as a high-energy radiation shield.


On the contrary, in the case of low-energy radiation, scattered rays may be effectively shielded only using substances having low atomic numbers, such as beryllium (4Be), aluminum (13Al), copper (29Cu), zinc (30Zn), water, paraffin, and polyethylene. The reason for this is that beta rays release a larger amount of braking X-rays (braking radiation) when beta rays react with a substance having a high atomic number.


Therefore, beta rays should be shielded using a substance having a low atomic number in order to reduce a conversion rate into braking X-rays. However, the protector for medical imaging of Related Art Document is not capable of completely preventing exposure to a small amount of generated braking X-rays, even when a substance having a low atomic number is used as a low-energy radiation shield.

When the first film fabric 110 is formed by stacking several sheets of the films 111 and 112 formed of the same material or different materials, each of the films 111 and 112 may be formed by stacking several sheets of the same films 111 or 112.


When the first film fabric 110 is formed by stacking several sheets of the films 111 and 112 formed of the same material or different materials, durability of the first film fabric 110 may be improved.


When the first film fabric 110 is formed by stacking several sheets of the films 111 and 112 formed of different materials, effects of shielding scattered rays by all the materials forming the respective films 111 and 112 may be obtained.


The first film fabric 110 is formed by stacking the plurality of thin films 111 and 112, thus being capable of having flexibility.

A plurality of attachment Velcro strips 1B V1B is provided at positions of the surface of the first front part 121A corresponding to the attachment Velcro strips 1A V1A provided on the rear surface of the shield 1A 210A (when the first shield 1A 210A covers the surface of the first front part 121A).


Further, a plurality of attachment Velcro strips 1B V1B is provided at positions of the surface of the second front part 122A corresponding to the attachment Velcro strips 1B V1B provided on the rear surface of the shield 1B 220A (when the second shield 1B 220A covers the surface of the second front part 122A).


As shown in FIGS. 20 and 21, the second shields 300A cover the first shields 200A at the positions of both of the patient's breasts. The second shields 300A are detachably attached to the surfaces of the first shields 200A. The second shields 300A include a shield 2A 310A and a shield 2B 220A.


The shield 2A 310A covers one of the patient's breasts. The shield 2A 310A is detachably attached mainly to the surface of the shield 1A 210A.


The shield 2B 320A covers the other of the breasts. The shield 2B 320A is detachably attached mainly to the surface of the shield 1B 220A.


At least one of the shield 2A 210A and the shield 2B 320A covers the part of the patient's body between both of the patient's breasts. FIG. 22 illustrates an embodiment in which the shield 2A 310A covers the part of the patient's body between both of the patient's breasts. Further, the shield 2A 210A and the shield 2B 320A extend toward the sides of the patient.


Therefore, during radiation therapy of a body part close to the breasts, such as the liver, pancreas, spleen, kidneys, cervical vertebral, lumbar, head and neck, etc., in order to allow scattered rays to reach the breasts at the front part of the chest and the sides of the patient, the scattered rays should pass through the second shields 300A after passing through the first shields 200A.


As shown in FIGS. 16, 20, 21 and 22, the shield 2A 310A and the shield 2B 320A are detachably attached to the surfaces of the first shields 200A by second attachment Velcro strips V2A and V2B.


The shield 2A 310A is detachably attached to the surface of the shield 1A 210A mainly in front of the first front part 121A by the second attachment Velcro strips V2A and V2B. The shield 2B 320A is detachably attached to the surface of the shield 1B 220A mainly in front of the second front part 122A by the second attachment Velcro strips V2A and V2B.


The second attachment Velcro strips V2A and V2B include attachment Velcro strips 2A V2A and attachment Velcro strips 2B V2B. The attachment Velcro strips 2A V2A and the attachment Velcro strips 2B V2B are detachably coupled to each other.


The attachment Velcro strips 2A V2A are provided on the rear surfaces of the shield 2A 310A and the shield 2B 310B. A plurality of attachment Velcro strips 2A V2A is provided along the edge of the rear surface of the shield 2A 310A. Further, a plurality of attachment Velcro strips 2A V2A is provided along the edge of the rear surface of the shield 2B 320A.

A plurality of attachment Velcro strips 2B V2B is provided at positions of the surface of the shield 1A 210A corresponding to the attachment Velcro strips 2A V2A provided on the rear surface of the shield 2A 310A (when the shield 2A 310A covers the surface of the shield 1A 210A).


Further, a plurality of attachment Velcro strips 2B V2B is provided at positions of the surface of the shield 1B 220A corresponding to the attachment Velcro strips 2A V2A provided on the rear surface of the shield 2B 220A (when the shield 2B 320A covers the surface of the shield 1B 220A).


One of the first shields 200A and the second shields 300A may include a substance having a relatively high atomic number, and the other of the first shields 200A and the second shields 300A may include a substance having a relatively low atomic number.


Substances having high atomic numbers may include elements, such as lead (82Pb), tungsten (74W), bismuth (83Bi), barium (56Ba), cadmium (48Cd), and tin (50Sn), and bismuth alloys (bismuth, cadmium, tin, lead, and indium). Further, substances having low atomic numbers may include elements, such as beryllium (4Be), aluminum (13Al), copper (29Cu), and zinc (30Zn), water, paraffin, and polyethylene.


As disclosed in Korean Patent Registration No. 1967664 and Japanese Patent Laid-open Publication No. 2015-225062, shields including elements having high atomic numbers and elements having low atomic numbers are known, and a method of manufacturing the same will thus be omitted.


Various types of radiation, such as high-energy photon beams, electron beams, proton beams, and heavy ion beams, are used in radiation therapy. Further, properties of scattered rays are varied depending on the type of radiation. Therefore, the scattered rays may be effectively shielded using a different shield depending on the type of radiation.


Braking radiation is electromagnetic radiation produced by deceleration of charged particles, such as electrons, when the charged particles are deflected by other charged particles, such as atomic nuclei. When an atomic nucleus attracts and deflects a beta (β-) ray and thus an acceleration is changed, photons with energy equal to an energy difference due to the change in the acceleration of the beta (β-) ray are released.


Negatively charged (−1) beta (β-) rays are attracted by positively charged (+) atomic nuclei. That is, the beta rays are deflected toward the atomic nuclei, and kinetic energy is reduced. As a result, braking radiation is emitted equal to an energy difference.


When substances having high atomic numbers, such as lead (82Pb), tungsten (74W), bismuth (83Bi), barium (56Ba), cadmium (48Cd), tin (50Sn), and bismuth alloys (bismuth, cadmium, tin, lead, and indium), are used as high-energy radiation shields, the degree of deflection of the beta rays is increased, and thus, probability of occurrence of braking radiation is raised. However, the protector for medical imaging of Related Art Document is not capable of preventing exposure to braking radiation, when a substance having a high atomic number is used as a high-energy radiation shield.


The scattered ray-shielding brassiere 10A, to which the radiation shielding principle for radiation therapy is applied, according to one embodiment of the present invention is manufactured such that the first shields 200A include a substance having a relatively low atomic number and the second shields 300A include a substance having a relatively high atomic number, thereby solving the above-described conventional problem.


That is, in the scattered ray-shielding brassiere 10A, to which the radiation shielding principle for radiation therapy is applied, according to one embodiment of the present invention, the second shields 300A primarily shield scattered rays of high-energy radiation, the first shields 200A secondarily shield braking radiation, and, thus, exposure of the patient's breasts to braking radiation is prevented during high-energy radiation therapy.


On the contrary, in the case of low-energy radiation, scattered rays may be effectively shielded only using substances having low atomic numbers, such as beryllium (4Be), aluminum (13Al), copper (29Cu), zinc (30Zn), water, paraffin, and polyethylene. The reason for this is that beta rays release a larger amount of braking X-rays (braking radiation) when beta rays react with a substance having a high atomic number.


Therefore, beta rays should be shielded using a substance having a low atomic number in order to reduce a conversion rate into braking X-rays. However, the protector for medical imaging of Related Art Document is not capable of completely preventing exposure to a small amount of generated braking X-rays, even when a substance having a low atomic number is used as a low-energy radiation shield.


The scattered ray-shielding brassiere 10A, to which the radiation shielding principle for radiation therapy is applied, according to one embodiment of the present invention is manufactured,


such that the first shields 200A include a substance having a relatively high atomic number and the second shields 300A include a substance having a relatively low atomic number, thereby solving the above-described conventional problem.


That is, in the scattered ray-shielding brassiere 10A, to which the radiation shielding principle for radiation therapy is applied, according to one embodiment of the present invention, the second shields 300A primarily shield scattered rays of low-energy radiation, the first shields 200A secondarily shield braking radiation, and, thus, exposure of the patient's breasts to braking radiation is prevented during low-energy radiation therapy. Further, in shielding scattered rays of low-energy radiation, only one of the first shields 200A and the second shields 300A may be used upon determining that the patient's breasts may be sufficiently protected using only one of the first shields 200A and the second shields 300A.


Neutron beams do not have any charge, and thus, the moving direction of beta rays is not deflected in the Coulomb's field of an atomic nucleus. Neutron beams collide with the atomic nucleus and lose energy and, in this case, lose energy easily as an atomic number decreases, and therefore, water, paraffin, and polyethylene including a large amount of hydrogen atoms or carbon atoms should be used as shields.


Therefore, during neutron therapy, the first shields 200A are manufactured to include a relatively low atomic number so as to prevent exposure of the patient's breasts to radiation during neutron therapy. During neutron therapy, the second shields 300A may be omitted.


The above-described first attachment Velcro strips V1A and V1B may be detachably attached to the front part 120A and the first shields 200A. Further, the second attachment Velcro strips V2A and V2B may be detachably attached to the first shields 200A and the third shields 300A.


Therefore, the second shields 300A may be attached to the surface of the wearing member 100A, and the first shields 200A may be attached to the surfaces of the second shields 300A. Thus, the positions of the first shields 200A and the second shields 300A may be adjusted depending on the kind of radiation used in radiation therapy.


As shown in FIGS. 14 to 16, the shoulder bands 400A are elements configured to compress the patient's breasts in front of the front part 120A. The shoulder bands 400A may include a first shoulder band 410A and a second shoulder band 420A.


One end of the first shoulder band 410A is coupled to the first front part 121A below the breasts. One end of the second shoulder band 420A is coupled to the second front part 122A below the breasts.


The shoulder bands 400A and the front part 120A may be coupled to each other by sewing, adhesion or heat fusion. Otherwise, the shoulder bands 400A and the front part 120A may be manufactured integrally. The shoulder bands 400A may be formed of an air equivalent material.


For example, the shoulder bands 400A may be formed of carbon fiber woven in the form of a mesh. When the shoulder bands 400A are woven in the form of a mesh, the shoulder bands 400A are easily deformed when external force is applied thereto. Therefore, the compressive force of the shoulder bands 400A is easily adjusted by external force.


As shown in FIGS. 15, 19a and 19b, the remaining ends of the shoulder bands 400A are detachably coupled to the back part 110A.


The first Velcro strips VC1 are provided on the back part 110A, and the second Velcro strips VC2 detachably coupled to the first Velcro strips VC1 are provided on the remaining ends of the shoulder bands 400A. The shoulder bands 400A and the back part 110A are detachably coupled to each other by the first Velcro strips VC1 and the second Velcro strips VC2. The first Velcro strips VC1 may be formed to have a greater area than the second Velcro strips VC2.


The middle parts of the shoulder bands 400A are adhered to patient's shoulders. When the positions of the second Velcro strips VC2 are adjusted, the detachable coupled positions of the shoulder bands 400A to the back part 110A may be variously adjusted. When the coupled positions of the remaining ends of the shoulder bands 400A to the back part 110A are adjusted, the positions of the patient's breasts may be changed.


The shoulder bands 400A are provided in the form of an overall long band. The shoulder bands 400A are provided in a form having a width which is gradually increased in a direction toward the front part 120A. Therefore, the shoulder bands 400A on the front part 120A cover the breasts.


When the remaining ends of the shoulder bands 400A are coupled to the back part 110A, the shoulder bands 400A in the state of covering the breasts provide elasticity to pull up the lower portion of the front part 120A. Therefore, the shoulder bands 400A pull up the lower breast tissues so as to prevent exposure of the breasts to radiation. The shoulder bands 400A compress the patient's breasts while maintaining a state in which tensile force is applied to the shoulder bands 400A.


When the coupled positions of the remaining ends of the shoulder bands 400A to the back part 110A are respectively adjusted, the compressive forces of the respective shoulder bands 400A on the front part 120A to the patient's breasts are adjusted. Therefore, the patient's chest may be compressed by proper compressive force. Further, even when the breast size and the chest size are changed due to a patient's weight change or only one breast size is changed, the patient's breasts may be stably supported by proper compressive forces.


As shown in FIGS. 19a and 19b, third Velcro strips VC3 detachably coupled to the second Velcro strips VC2 are provided on the remaining ends of the shoulder bands 400A. At the time of storing and washing the wearing member 100A, when the second Velcro strips VC2 are coupled to the third Velcro strips VC3, damage to the second Velcro strips VC2 and the wearing member 100A, and tangling of the wearing member 100A may be prevented.


A fourth Velcro strip VC4 is provided at one side of the remaining end of each of the shoulder bands 400A based on the second Velcro strip VC2, and a fifth Velcro strip VC5 is provided at the other side of the remaining end of each of the shoulder bands 400A based on the second Velcro strip VC2.


As shown in FIG. 19c, when the remaining end of the shoulder band 400A is rolled up in the length direction and then the fourth Velcro strip VC4 and the fifth Velcro strip VC5 are coupled to each other, the rolled-up state of the remaining end of the shoulder band 400A is maintained. Therefore, in order to store and wash the wearing member 100A, when the remaining ends of the shoulder bands 40A are rolled up in the length direction and the fourth Velcro strips VC4 and the fifth Velcro strips VC5 are coupled to each other, damage to the second Velcro strips VC2 and the wearing member 100A, and tangling of the wearing member 100A may be prevented.


Although the exemplary embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications and variations are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.


Therefore, all such and other modifications and variations thereto as would be apparent to those skilled in the art are deemed to fall within the broad scope and ambit of this present invention as is herein set forth.
