Description

BRASSIERE FOR RADIATION TREATMENT}

The present invention relates to a brazier for radiation therapy, and more particularly, to a brazier for radiation therapy that collects breasts of a patient and prevents flow during radiation treatment of the breast area.

Methods of breast cancer treatment include surgical resection, radiation therapy, chemotherapy, and hormone therapy, and there are differences in treatment methods depending on the stage. In early cases, radiotherapy is performed along with lump resection.

When planning radiation therapy for breast cancer, the radiation dose to the contra-lateral breast and the lung located inside the chest wall, the reproducibility of the patient's posture, and the patient's fixation effect should be considered as important factors.

In order to irradiate an appropriate dose to the breast, chest wall, and loco-regional lymphatics during radiation therapy, the use of a patient fixing device is required to ensure reproducibility of the correct patient posture during treatment.

Variables exist in the two-dimensional radiation treatment plan, which is generally used, and the organ delineation between the tumor and the sensitive tissue is unclear, or the shape and boundary problems of the beam, biological considerations, and tumors. It is necessary to consider dose heterogeneity and patient posture and movement.

Republic of Korea Patent Publication No. 1888510 discloses a radiation therapy bra. Registered Patent Publication No. 1888510 is a bra, comprising: two breast cups; A visually transparent midsole placed between the two breast cups; 2 shoulder straps to support the 2 breast cups; It characterized in that it comprises a; shoulder strap and a rear band coupled to the two breast cups.

Excessively large or sagging breasts form severe irregularities when enlarged skin tissue is placed in the breast cup. However, in Korean Patent Publication No. 1888510, since the breast cup is made of thin fibers, there is a problem in that it is difficult to press the severe uneven areas completely flat with the elasticity of the thin fibers.

In addition, Korean Patent Publication No. 1888510 discloses that the breast cup, shoulder strap, and rear band form a detachable structure to form tension to support the breast cup, but the length adjustable range of the shoulder strap and the rear band is relatively small. Therefore, there was a problem of excessive pressure on the chest of a patient with a large chest circumference.

In addition, Korean Patent Publication No. 1888510 has a disadvantage in that the position of the patient's breast depends on the shape of the breast cup, since the shoulder strap simply connects the breast cup and the rear band. In the case of a weakened patient, it is difficult to maintain a specific posture on the couch. In order for the radiation to be smoothly irradiated to cancer cells in a specific location of the breast, a technology capable of finely adjusting the location of the breast is required while the location of the patient on the couch remains unchanged.

Republic of Korea Patent Publication No. 1888510 (Registration Date: 2018.08.08)

An object of the present invention is a radiation therapy brazier made to finely adjust the position of the breast in a state where the patient's posture is not changed while pressing the breast so that the irregularities of the breast skin tissue are flat Is to provide.

As shown in FIG. 1, during the radiation treatment of the breast area, the patient (not shown) lies on the couch 2, and the radiation generated by the radiation treatment device 1 is irradiated to the lesion area of the breast.

As shown in Figs. 2 to 4, the brazier 10 for radiation therapy according to an embodiment of the present invention collects the breasts of the patient 11 and maintains a constant breast position during radiation treatment of the breast area, It is configured to include a pair of cup members 100, a bolus 200 and a contact member 300.

As shown in FIG. 2, a pair of cup members 100 are configured to respectively surround the breast of the patient 11, and include a first cup member 100A and a second cup member 100B.

The first cup member 100A is configured to surround the left breast of the patient 11. The second cup member 100B is configured to surround the right breast of the patient 11.

The first cup member 100A and the second cup member 100B may form a symmetrical structure with each other. That is, the first cup member 100A and the second cup member 100B may have the same structure except that they have a symmetrical structure. Hereinafter, the cup member 100 should be understood to mean the first cup member 100A and the second cup member 100B.

As shown in FIG. 4, the cup member 100 is manufactured including an inner skin 110 and an outer skin 120. The inner skin 110 and the outer skin 120 are formed of a fibrous material. In order to block the leakage of the bolus 200, the inner skin 110 and the outer skin 120 may be formed of a waterproof material. Alternatively, the inner skin 110 and the outer skin 120 may be coated with a waterproof coating.

The endothelium 110 is in close contact with the breast. The outer skin 120 covers the endothelium 110 on the opposite side of the breast. The edge portions of the inner skin 110 and the outer skin 120 are coupled to each other. The inner skin 110 and the outer skin 120 may have edge portions bonded to each other or thermally fused. Accordingly, the inner skin 110 and the outer skin 120 form a lead-in space 101 therebetween.

5 is an illustration for explaining a state in which the endothelium 110 elastically collects the breast of the patient 11. It should be understood that the remaining configurations of the bra 10 except for the endothelium 110 in FIG. 5 are not shown. The thick dotted line in FIG. 5 denotes a radiation treatment field margin.

As shown in FIG. 5(a), the endothelium 110 elastically supports the inner breast of the patient 11. The thin dotted line in FIG. 5 means the direction of elasticity formation of the endothelium 110. When the breasts of the patient 11 are close to each other, the dose of the opposite breast may be increased by radiation irradiated to one breast and scattered rays of the radiation. The endothelium 110 elastically supports the inner breast of the patient 11, thereby preventing an increase in the dose of the opposite breast.

As shown in FIG. 5(b), the endothelium 110 elastically supports the outer breast of the patient 11 to prevent the enlarged breast from being folded. FIG. 6(a) shows a tomography image of a patient wearing a bra, and FIG. 6(b) shows a tomography image of a patient without a bra.

As shown in Fig. 6(a), when a bra is worn, elastically gathered breasts can be checked. As shown in Fig. 6(b), it can be seen that the outer portion of the enlarged breast is folded when the bra is not worn. When the outer part of the breast is folded, the skin tissue is damaged at the folded part during radiation treatment, and a change in radiation dose occurs.

As shown in FIG. 5, the endothelium 110 is formed of an elastic material and functions to elastically collect the breast of the patient 11. When the endothelium 110 collects the chest of the patient 11, the degree to which radiation irradiated to the lesion of the breast passes through the breast and reaches the heart and lungs is reduced.

As shown in FIG. 4, the bolus 200 is a configuration in which the endothelium 110 is in close contact with the breast, and is inserted into the retractable space 101. S, which is not described in FIG. 4, refers to a space where the breast is located.

If the body surface of the part for the purpose of irradiation is oblique or the irregularities are strong, it becomes difficult to calculate the dose. Therefore, by loading a material of tissue and isometric weight on the body surface, the surface is conveniently flattened and irradiated. The material used at that time is called a bolus (200; bolus). As the material of the bolus 200, a tissue equivalent material is used.

Tissue-equivalent material is a material that exhibits absorption and ionization equivalent to that of any living tissue for radiation. Typically, water is used. There is also a gel-like tissue equivalent that is a mixture of water, gelatin, glycerol and saccharose.

In addition, in the case of radiation treatment of an enlarged breast, it is necessary to increase the transmittance of radiation by using high energy radiation. However, high-energy radiation causes a decrease in skin dose instead of strong penetration. When a tissue equivalent material is inserted into the insertion space 101, the skin dose may be increased during radiation treatment of an enlarged breast.

As shown in Figure 4, when the bolus 200 is provided with a gel-like tissue-equivalent material, the elastic strap 323, which will be described later, provides a passage through which the bolus 200 enters and exits the inlet space 101. To form. 324 shown in FIGS. 2 and 4 refers to the inlet and outlet 324 formed on the elastic strap 323. The entrance/exit 324 is connected to the passage.

The medical staff may open the entrance/exit 324 to enter and exit the bolus 200 into the entry space 101 through the passage. The entrance/exit 324 may be opened and closed by Velcro (not shown).

As shown in Figure 2, the cup member 100 is coupled to the first passage member 102 and the second passage member 103. The first passage member 102 and the second passage member 103 positioned inside the radiation treatment field are formed of a fibrous material. This is because, when the first passage member 102 and the second passage member 103 are formed of a plastic material, it acts as a factor of changes in skin dose and generation of scattered rays, thereby causing anomalous change in skin dose.

The first passage member 102 forms a passage through which air between the endothelium 110 and the breast escapes. One end of the first passage member 102 is coupled to the endothelium 110, and the other end of the first passage member 102 is coupled to the first tube T1 outside the radiation treatment field.

When the patient 11 wears the bra 10, the medical staff may connect a syringe or a vacuum pump to the first tube T1 to extract air between the endothelium 110 and the breast. The endothelium 110 is completely in close contact with the breast. After removing the air, a stopper is put on the other end of the first tube T1.

As shown in FIG. 7, the second passage member 103 forms a passage through which air between the outer shell 120 and the bolus 200 escapes. One end of the second passage member 103 is coupled to the shell 120, and the other end of the second passage member 103 is coupled to the second tube T2 outside the radiation treatment field.

Rings R for preventing air clogging may be coupled inside the first passage member 102 and the second passage member 103, respectively. The ring R may be made of an air equivalent material such as carbon.

When the patient 11 wears the bra 10, the medical staff may connect a syringe or a pump to the second tube T2 to remove air between the outer shell 120 and the bolus 200. The bolus 200 is completely in close contact with the inner skin 110 and the outer skin 120. After removing the air, a stopper is put on the other end of the second tube T2. In Fig. 7, the stopper is indicated by a dotted line.

Air between the breast, the endothelium 110, the bolus 200 and the outer skin 120 is removed by the above process. Even if the pressure of the breast is applied to the endothelium 110, the endothelium 110 maintains its shape by the bolus 200 and supports the surface of the breast with a uniform pressure.

On the other hand, when the bolus 200 is provided with water, the inlet and outlet 324 of the bolus 200 may not be formed in the elastic strap 323. Alternatively, the inlet and outlet 324 may be blocked by adhesion or heat fusion. The first passage member 102 forms a passage through which air between the endothelium 110 and the breast escapes.

When the bolus 200 is provided with water, the second passage member 103 forms a passage through which the bolus 200 enters and exits the inlet space 101. One end of the second passage member 103 is coupled to the shell 120, and the other end of the second passage member 103 is coupled to the second tube T2 outside the radiation treatment field. The medical staff may connect the syringe to the second tube T2 to insert or remove the bolus 200 into or out of the insertion space 101.

As shown in Fig. 3, the other ends of the 1-1 strap 321 and 1-2 strap 322 are detachably coupled to the band 310 by a hook (H) or Velcro (V). . The medical staff may adjust the coupling position of the band 310 with the other end of the 1-1st strap 321 and 1-2nd strap 322 according to the breast position and chest circumference of the patient 11.

The elastic strap 323 is coupled to the lower portion of the cup member 100. The elastic strap 323 wraps the abdomen and both sides of the patient 11 under the cup member 100. Both ends of the elastic strap 323 are detachably coupled to the band 310 by hooks (H) or Velcro (V).

As shown in FIGS. 2 and 3, the second strap 330 connects the cup member 100 and the band 310 at each of the shoulder portions of the patient 11. The second strap 330 is made of a fibrous material having elasticity and is in close contact with both shoulders of the patient 11.

That is, one second strap 330 connects the first cup member 100A and the first band 311 at one shoulder of the patient 11. In addition, the second strap 330 on the opposite side connects the second cup member 100B and the second band 312 at the shoulder portion on the opposite side of the patient 11.

Each of the second straps 330 includes a 2-1 strap 331 and a 2-2 strap 332. One end of the 2-1 strap 331 and the 2-2 strap 332 are coupled to the upper portion of the cup member 100. One ends of the 2-1 strap 331 and the 2-2 strap 332 are spaced apart in the horizontal direction.
