Breast cancer patient radiotherapy tissue equivalent filler fixing device

Abstract

The invention discloses a breast cancer patient radiotherapy tissue equivalent filler fixing device. The device comprise a filler body, trapezoidal elastic breathable bandages are bonded and fixed atthe top and the bottom of the filler body respectively; a male hook-and-loop fastener and a female hook-and-loop fastener are respectievly sewn on one sides, away from each other, of the two trapezoidal elastic breathable bandages; two transverse bendable plastic shaping strips and two vertical bendable plastic shaping strips are bonded and fixed to the front side of the filler body; and the two transverse bendable plastic shaping strips are located between the two vertical bendable plastic shaping strips. The design is reasonable, and the shape of the filler body can be conveniently changed according to actual requirements, so that the filler body can be stably attached to physiological curved surfaces of different human bodies, and the attachment degree is improved. The position of a pressing belt can be conveniently adjusted, the pressing belt can be conveniently and rapidly fixed, and the pressing and fixing force on the pressing belt can be conveniently adjusted, so that the filler body can be stably and rapidly fixed, displacement of the filler body is effectively prevented, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of radiotherapy auxiliary appliances, in particular to a radiotherapy tissue-equivalent filler fixation device for breast cancer patients. Background technique [0002] Tissue Equivalent Compensation (Bolus) (also known as filler) is a special auxiliary item for radiotherapy, which is quadrangular in shape and generally composed of substances with a density equal to that of human tissue; the most common clinical method is chest wall filling for mastectomy and radical mastectomy The application of drugs is more common, especially for locally advanced breast cancer, which can make the chest wall skin and subcutaneous tissue prone to residual cancer cells receive higher irradiation doses, and play a role in killing residual cancer cells and avoiding adverse effects on the lungs, heart and great vessels. The role of necessary irradiation; commonly used fillers are paraffin, vaseline, special silica gel or even p...

AI Technical Summary

Problems solved by technology

[0004] The radiotherapy tissue-equivalent filler fixation device for breast cancer patients disclosed in the above-mentioned patent still has some deficiencies. It simply presses the filler by pressing the belt, which cannot effectively and stably ensure the tight fit between the filler and the skin. Poor disadvantages, and the phenomenon of filler displacement is easy to occur, (mainly reflected in the use of the physiological surface of the human body, although the filler can be simply pressed out by the pressure belt, but its curvature is difficult to adapt to people with different physiological surfaces , resulting in poor fit and unsatisfactory effect), in view of this phenomenon, we propose a radiotherapy tissue-equivalent filler fixation device for breast cancer patients to solve the above problems
