Description

Compensator Apparatus for Photon Light Therapy {BOLUS DEVICE FOR TREATMENT USING PHOTON}

The present invention relates to a compensator mechanism used in the treatment of photo-rays, and more particularly, to a compensator mechanism that can be used to maximize the effect of photo-rays treatment and can be used without restriction on the affected part of the patient.

Kaposi's Sarcoma, which is caused by an AIDS-related infection or immunodeficiency associated with organ transplantation, is sensitive to radiation. A cure rate of can be obtained. In order to treat Kaposi's sarcoma of the extremities, radiation therapy is widely used as a general treatment.

Kaposi's sarcoma can occur in many parts of the body, but it is most common to involve the lower extremities, and it can also slow the lymph vessels and cause swelling. It can be located up to 1.5 ~ 2 cm deep from the surface of the skin, and the standard treatment is to treat the tumor evenly with the appropriate margin on the affected skin.

If the affected area is small in the early stage of development, there is no problem, but if multiple lesions are formed in multiple cases, the radiotherapy range is inevitably increased. However, when the treatment range is increased in this way, it is difficult to investigate the homogeneous radiation dose in the entire treatment area due to various bending and thickness variations of the lower limbs.

In this case, a counter-entry irradiation using high-energy photon rays, such as radiation, is applied, and a compensator is used to reduce the radiation dose to the skin surface, which is a target tumor, and rice is mainly used as a compensator.

Rice has the advantage of being able to apply conventional radiation equipment without any equipment except for a box which is relatively easy to use and can hold rice. However, rice has a density of 1.35 g / cm3 and a density of water of 1.00 g / cm3 (4 ℃) is less useful as a tissue equivalent material and has a disadvantage in that the density of the rice is changed every treatment because the dry state is changed over time. In addition, in the case of rice, there is a disadvantage that the density is not uniform because of the presence of pores structurally.

However, in the case of water bolus, there is an excellent effect on increasing the skin surface dose without generating an air layer generated from rice bolus, but there is a disadvantage in that ease of use when applied to the treatment of patients. In addition, when the water directly comes into contact with the patient's skin there is a risk of infection, etc. It is not easy to actually use the water bolus.

Specifically, when rice bolus is used, handling is not easy because it does not use an airtight container, but when water is used, the bolus itself must be waterproof, and if it is poured, the risk of mechanical damage due to water leakage may occur. There is discomfort that requires special attention on use.

In addition, there are cases where it is difficult to apply depending on the treatment area of the body. For example, applying water bolus to treat lower extremities below the knee may cause the patient to have to sit on the treatment table and sit on it to treat the lesion. The application of water bolus is virtually impossible if it comprises the knee top.

The present invention provides a compensator device useful for irradiating homogeneous photon dose to a treatment area.

In addition, the present invention can solve the heterogeneity of the photon dose by minimizing the air layer between the compensator and the treated lesion, thereby providing a compensator mechanism that is easy to transfer the photon dose to the treated lesion and predict the effect.

In addition, the present invention can use water as a compensator capable of evenly irradiating high-energy photon rays such as radiation to the treatment target area, the air layer between the compensator and the treated lesion can be removed, and mechanical damage and body treatment due to water leakage Provided is a compensator mechanism that can overcome site constraints.

According to one exemplary embodiment of the invention, the compensator device comprises a receptor body and a body receptacle.

The receptor body accommodates a compensator, the body receiving portion forms a space for accommodating a body part inside the receptor body, and the space for accommodating the body part is blocked from the space inside the receptor body. The compensator is provided to be similar to the density of the body. Thus, after penetrating a predetermined depth, it is possible to make the therapeutic effect of photon rays, which show a therapeutic effect, appear from the surface of the patient's skin.

In addition, an insertion hole through which the body can pass may be formed in the receptor body, and the body receiving portion may extend into the receptor body based on the insertion hole to provide a blocked space. In this case, it is preferable to form the body accommodating part with a waterproof material, and the body accommodating part may include an internal body accommodating part and an external accommodating part extending from the insertion hole to the inside and the exterior of the acceptor body, respectively.

In addition, the insertion hole may be provided with a sealing member, the sealing member may be coupled to the inner body receiving portion and the outer body receiving portion mutually, the coupling between the body receiving portion and the receptor body. Thus, water may be used as a compensator, and water may be used to provide a more uniform photon dose to the treatment site.

In addition, when a patient inserts a part of the body into the body receiving body, there is no risk of water leakage even if the direction is inserted from the top or the side, thereby preventing damage to peripheral devices and reducing the restriction on the treatment area of the body. .

The compensator device of the present invention can irradiate a uniform photon dose to the treatment site, and the therapeutic effect of photon rays, which show a therapeutic effect only after penetrating a predetermined depth, appears from the skin surface of the patient.

The compensator mechanism of the present invention is excellent in sealing property between the body accommodating portion into which the body is inserted and the receiver main body, thereby preventing malfunction of peripheral devices due to leakage even when water is used as the compensator.

The compensator mechanism of the present invention is not limited to the direction in which the treatment area of the patient is inserted into the body receiving body, and can treat the affected area even without lateral influence even if it is lateral.

The compensator mechanism of the present invention can solve the heterogeneity of the photon dose by minimizing the air layer between the compensator and the treated lesion, thereby transferring the photon dose to the treated lesion and predicting the effect.
