Description

Bras for radiation therapy

The present invention relates to a bra for radiation therapy, and more particularly, to a bra for radiation therapy that collects and prevents flow of a patient's breast during radiation treatment of a breast region.

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 lumpectomy.

When planning radiation therapy for breast cancer, the radiation dose to the contra-lateral breast and lung located inside the chest wall, reproducibility of patient posture, and patient 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 fixation device is required to ensure the reproducibility of the correct patient posture during treatment.

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

Korean Patent Publication No. 1888510 discloses a radiotherapy bra. Korean Patent Publication No. 1888510 discloses a bra, including two breast cups; a visually transparent central window positioned between the two breast cups; 2 shoulder straps to support 2 breast cups; A shoulder strap and a rear band coupled to the two breast cups; characterized in that it is configured to include.

Excessively large or sagging breasts form severe irregularities with the enlarged skin tissue placed in the breast cup. However, Patent Registration No. 1888510, since the breast cup is made of thin fibers, there was a problem in that it is difficult to press the severe irregularities due to the elasticity of the thin fibers to the extent that they are completely flat.

In addition, according to Korean Patent Publication No. 1888510, the breast cup, shoulder strap, and rear band form a detachable structure to form a tension supporting the breast cup, but the adjustable range of the shoulder strap and the rear band is relatively small. Therefore, there was a problem of excessively compressing 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 has only a function of simply connecting the breast cup and the rear band. In the case of a weakened patient, it is not easy to maintain a specific posture on the couch. In order for radiation to be smoothly irradiated to cancer cells located in a specific position in the breast, a technology that can finely adjust the position of the breast without changing the position of the patient on the couch is required.

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

It is an object of the present invention, while pressing the breast so that the unevenness of the breast skin tissue is flat, without excessively compressing the chest of the patient, and a radiotherapy bra made to finely adjust the position of the breast while the patient's posture does not change is to provide

The above object, according to the present invention, each wraps the breast of the patient, the cup member to form an inlet space therein; a bolus introduced into the inlet space; and a close contact member for adhering the cup member to the breast, wherein the cup member includes: an endothelium adhering to the breast; And it is achieved by a brazier for radiation therapy, characterized in that it comprises a shell for forming the inlet space between the endothelium and the endothelium.

The bolus is made of a gel-like tissue equivalent material, the adhesion member forms a passage through which the bolus enters and exits the inlet space, and the air between the endothelium and the breast escapes through the cup member. The outgoing first passage member and the second passage member through which air between the shell and the bolus exit may be coupled to each other.

The bolus may be made of water, and a first passage member through which air between the endothelium and the breast escapes may be coupled to the cup member, and a second passage member through which the bolus enters and exits the inlet space.

As shown in FIG. 1 , during radiation treatment of the breast, a 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 Figures 2 to 4, the bra 10 for radiation therapy according to an embodiment of the present invention collects the breasts of the patient 11 during radiation treatment of the breast region and keeps the breast position constant, It is configured to include a pair of cup member 100 , a bolus 200 and a contact member 300 .

As shown in FIG. 2 , the pair of cup members 100 each 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 to include an inner shell 110 and an outer shell 120 . The endothelium 110 and the outer skin 120 are formed of a fibrous material. In order to block the leakage of the bolus 200, the inner shell 110 and the outer shell 120 may be formed of a waterproof material. Alternatively, the inner shell 110 and the outer shell 120 may be coated with a waterproof coating.

The endothelium 110 is in close contact with the breast. The sheath 120 covers the endothelium 110 on the opposite side of the breast. The endothelium 110 and the outer shell 120 are coupled to each other at the edges. The endothelium 110 and the outer shell 120 may have edges adhered to each other or heat-sealed. Accordingly, the endothelium 110 and the outer shell 120 form an inlet space 101 therebetween.

5 is a diagram for explaining a state in which the endothelium 110 elastically gathers the breast of the patient 11 . It should be understood that the remaining components of the bra 10 except for the endothelium 110 in FIG. 5 are not shown. A thick dotted line in FIG. 5 means a radiation treatment field margin.

As shown in Figure 5 (a), the endothelium 110 elastically supports the inner breast of the patient (11). The thin dotted line in FIG. 5 means the elastic formation direction of the endothelium 110 . When the breasts of the patient 11 come closer to each other, the dose to 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 not wearing a bra.

As shown in FIG. 6( a ), when a bra is worn, elastically gathered breasts can be identified. As shown in FIG. 6( b ), it can be seen that the outer part of the enlarged breast is folded when the bra is not worn. When the outer part of the breast is folded, the skin tissue in the folded part is damaged during radiation therapy, 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 gather the breasts of the patient 11 . When the endothelium 110 collects the chest of the patient 11, the degree of radiation irradiated to the lesion of the breast passing through the breast and reaching the heart and lungs is reduced.

As shown in FIG. 4 , the bolus 200 is configured to adhere the endothelium 110 to the breast, and is introduced into the inlet space 101 . S, which is not described in FIG. 4, means a space in which the breast is located.

If the body surface of the part to be irradiated is slanted or has strong irregularities, it becomes difficult to calculate the dose. Therefore, the tissue and the material of equal specific gravity are loaded on the body surface and the surface is flattened for convenience. The material used at that time is called a bolus (200; bolus). As a material of the bolus 200, a tissue equivalent material is used.

A tissue-equivalent material is a material that exhibits absorption and ionization equivalent to that of any living tissue with respect to radiation. Typically, water is used. There is also a tissue equivalent material in a gel state, which is a mixture of water, gelatin, glycerol, and saccharose.

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

As shown in FIG. 4 , when the bolus 200 is provided with a gel-like tissue equivalent material, the elastic strap 323 to be described later forms a passage through which the bolus 200 enters and exits the inlet space 101 . to form 324 shown in FIGS. 2 and 4 means the inlet and outlet 324 formed in the elastic strap 323 . The inlet and outlet 324 are connected to the passage.

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

As shown in FIG. 2 , the first passage member 102 and the second passage member 103 are coupled to the cup member 100 . 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, they act as a factor in the change of skin dose and generation of scattered rays, thereby anomalously changing the 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 draw air between the endothelium 110 and the breast by connecting a syringe or a vacuum pump to the first tube T1. The endothelium 110 is completely in close contact with the breast. After the air is removed, the other end of the first tube T1 is covered with a stopper.

As shown in FIG. 7 , the second passage member 103 forms a passage through which air between the shell 120 and the bolus 200 exits. 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.

A ring (R) for preventing air clogging may be coupled to the inside of 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 draw out air between the shell 120 and the bolus 200 . The bolus 200 is completely in close contact with the endothelium 110 and the outer skin 120 . After the air is removed, the other end of the second tube T2 is covered with a stopper. In Fig. 7, the closure is indicated by a dotted line.

The air between the breast, the endothelium 110 , the bolus 200 and the outer shell 120 is removed by the above process. Even when 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 thermal 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 insert or remove the bolus 200 into or out of the inlet space 101 by connecting the syringe to the second tube T2 .
