Description

Technical Field

[0001] The utility model relates to the field of body position fixing structures, in particular to a positioning pillow for breast radiotherapy. Background Art

[0002] Taking breast cancer as an example, breast cancer is the most common malignant tumor in women, and its incidence rate ranks first among malignant tumors in women. Radiotherapy is one of the important treatment methods for breast cancer. Most patients need radiotherapy after radical surgery and breast-conserving surgery. The human breast is rich in connective tissues such as fat, and there is no bone or skeletal muscle support to fix it. Its shape and position are easy to change, and its volume changes with the size of external force. The breast is located on the chest wall, and its position can change with the respiratory activity. For some breast cancer patients with small body size, the chest wall becomes thin and even close to the lung tissue after modified radical surgery. Therefore, based on the unstable shape of the breast, displacement with respiratory movement, and the thickness of the chest wall, the repeatability of the patient's position is very important during radiotherapy, which directly affects the accuracy of radiotherapy, the amount of radiation received by the target area and the protected organs, especially with the widespread application of conformal intensity modulation and other technologies, the fixation of the position determines the effect of treatment and the incidence of complications. At present, the main fixation devices for breast cancer patients include vacuum bags, breast brackets, thermoplastic body membranes and other fixation devices.

[0003] The above-mentioned thermoplastic film uses an S-shaped head, neck, shoulder board and an abdominal plate to achieve positioning, and has good repeatability, but it needs to be spliced ​​for use, and the comfort and matching are not well improved. The negative pressure vacuum pad is inconvenient to make marking points and marking lines, and the patient and the membrane cannot fit well. In addition, during radiotherapy, some negative pressure vacuum pads will leak, causing secondary positioning of the patient, increasing the patient's expenses, and the patient is often in a forced position, which is very painful. This will cause unconscious movement, resulting in increased errors in radiotherapy and greatly reduced the efficacy of radiotherapy.

[0004] Therefore, it is necessary to improve the above problems. Utility Model Content

[0005] The utility model aims to provide a positioning pillow for breast radiotherapy, so as to solve the problems that the supporting positioning mechanism used in the existing radiotherapy has poor comfort and matching and often puts the patient in a forced position, thereby greatly reducing the effect of radiotherapy.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A positioning pillow for breast radiotherapy comprises an integrally formed polylactic acid half-body fitting mold pillow, the polylactic acid half-body fitting mold pillow comprising an upper chest fitting limit portion, an arm fitting limit portion and a head fitting limit portion, the arm fitting limit portion being arranged at the front ends of both sides of the upper chest fitting limit portion, and the head fitting limit portion being arranged at the middle part of the front end of the upper chest fitting limit portion.

[0008] The positioning pillow adopts one-piece molding technology, which can fit the human body well, solving the problem of poor matching of the supporting positioning mechanism used in radiotherapy. The material used is polylactic acid, which solves the problem of comfort well, and there will be no air leakage and no increase in patient costs. The upper chest fitting limiter can limit the upper chest of the patient when lying down, the arm fitting limiter can limit the patient's arms, and the head fitting limiter can limit the patient's head. The limitation of these three parts can well position the patient's upper body, making it difficult for the patient's upper body to move during radiotherapy, thereby improving the efficiency and effect of radiotherapy.

[0009] As a further preferred embodiment of the present invention, the arm fitting limit portion is an arm upper arm fitting limit portion.

[0010] It is only necessary to limit the upper arm connected to the body, which can reduce the amount of material used and reduce costs while playing a good limiting role. A strip-shaped forearm support structure is also provided at the bottom of the arm fitting limiting part.

[0011] As a further preferred embodiment of the present invention, a neck fitting limit portion is further provided between the head fitting limit portion and the upper chest fitting limit portion.

[0012] As a further preferred embodiment of the present invention, the head fitting limiting portion includes a supporting structure and a head fitting structure which are sequentially arranged from bottom to top.

[0013] The support structure can provide support for the head.

[0014] As a further preferred embodiment of the present invention, the support structure includes a stable support pad and a support column arranged in sequence from bottom to top, and a head fitting concave surface is provided on the top of the support column.

[0015] The stable support pad can increase the contact surface and improve the stability of the support, and the head-fitting concave surface can fit well with the bottom surface of the head.

[0016] As a further preferred embodiment of the present invention, ear-lowering notches are provided on both sides of the head fitting structure.

[0017] When the patient lies down, the ear can be inserted into the notch below the ear, which is more comfortable.

[0018] As a further preferred embodiment of the present invention, the thickness of the one-piece polylactic acid half-body fitting mold pillow ranges from 0.8 to 1.4 cm.

[0019] This thickness range can ensure both therapeutic effects and a certain degree of comfort.

[0020] Compared with the prior art, the utility model can achieve at least one of the following beneficial effects:

[0021] 1. The positioning pillow adopts one-piece molding technology, which can fit the human body well, solving the problem of poor matching of the support positioning mechanism used in radiotherapy. The material used is polylactic acid, which solves the comfort problem well, and there will be no air leakage, which will not increase the patient's cost.

[0022] 2. The upper chest fitting limiter can limit the position of the patient's upper chest when the patient is lying down, the arm fitting limiter can limit the position of the patient's arm, and the head fitting limiter can limit the position of the patient's head. The limitation of these three parts can well position the patient's upper body, making it difficult for the patient's upper body to move during radiotherapy, thereby improving the efficiency and effect of radiotherapy.

[0023] 3. It is only necessary to limit the upper arm connected to the body. This can reduce the amount of material used and reduce costs while playing a good limiting role.

[0024] 4. The supporting structure can support the head.

[0025] 5. The stable support pad can increase the contact surface and improve the stability of the support. The concave surface of the head can fit well with the bottom surface of the head.

[0026] 6. When the patient lies down, the ear can be inserted into the notch below the ear, which is more comfortable. BRIEF DESCRIPTION OF THE DRAWINGS
