Device for managing thoracic and abdominal respiratory movement through abdominal compression and manufacturing method

Abstract

The invention relates to a device for managing thoracic and abdominal respiratory movement through abdominal compression and a manufacturing method, and belongs to the technical field of medical instruments. Through a method for scanning and positioning CT / MRI by conducting compression deformation on an abdomen positioning image of a patient or holding breath after the patient exhales to the maximum degree, an abdomen compression layer conforming to the body shape and the anatomical structure (tumor) of the patient is designed, the abdomen compression layer and a fixing body film are integrally formed in a 3D printing mode through a 3D printer, the abdomen is tightly compressed and wrapped in an all-dimensional and dead-angle-free mode, and gaps or spaces of abdominal visceral organs moving along with breathing are reduced to the maximum extent. According to the method, abdominal respiration of the patient can be converted into shallow chest respiration as far as possible, so that the abdominal respiration movement amplitude of the patient can be controlled to be 0.5 cm or below, the movement amplitude of thoracic and abdominal tumors along with respiration is effectively reduced, operation is easy and convenient, repeatability is high, the patient comfort degree is high, and precise radiotherapy is promoted to the maximum extent.

Description

technical field [0001] The invention relates to a device and a manufacturing method for managing chest and abdomen breathing movement through abdominal compression, belonging to the technical field of medical devices. Background technique [0002] Radiation therapy (radiotherapy) is one of the main treatments for cancer. Radiation therapy uses ionizing radiation such as high-energy X-rays, electrons, and proton heavy ions to kill tumor tissues in the body. Due to the penetrating nature of rays, high-energy rays will inevitably damage normal organs and tissues of the human body while killing tumors, such as skin damage, radiation pneumonitis (chest tumors such as lung cancer), radiation enteritis (abdominal tumors), swallowing Impaired function (head and neck tumors), etc. Severe injuries can even lead to bowel perforation, blindness, paralysis, and even death. Therefore, radiotherapy uses a variety of hardware and software equipment, devices, methods and processes in orde...

Problems solved by technology

However, in the use of this abdominal compression device, there are still many large gaps between the fixed body membrane and the patient's body surface. When the abdominal compression is performed, human muscles and soft tissues will be uncontrollably extruded with the abdominal wall. It is still difficult to ensure that the control of abdominal breathing movement is always the same as when making a radiotherapy plan; and the product is handmade, and the production accuracy varies greatly due to factors such as the experience of the maker; in addition, the abdominal compression device is not compatible with The fixed body membrane is made in one piece, so before each radiotherapy, it is necessary to use the metal marking point to confirm whether the position of the compression device is consistent with the radiotherapy plan, and the operation is time-consuming and cumbersome
