Breathing control positioning device for radiation treatment of thoracic cancer

Abstract

The invention discloses a breathing control positioning device for the radiation treatment of thoracic cancer, and the device comprises a bottom plate and a bed plate. Moreover, the four corners of the surface of the bottom plate are connected with bottom four corners of the bed plate through supporting rods. Two sides of the central part of the bed plate are provided with two symmetric through holes. The surface, corresponding to the through holes, of the bottom plate is provided with a hydraulic cylinder, and the central part of the surface of the hydraulic cylinder is connected with telescoping rods. The tops of the two telescoping rods pass through the through holes, and then are connected with two ends of a breathing limiting plate. A groove at the bottom of the breathing limiting plate is provided with an infrared inductor, and the bottom surface of the breathing limiting plate is connected with a rubber air bag. One end of the rubber air bag is provided with an air inlet valve, and the air inlet valve is connected with an air pump through an air guide pipe. A controller is electrically connected with an infrared sensor and an air pump. The other end of the rubber air bag is provided with an air discharge valve. The device is high in reuse rate, is low in cost, can effectively control the amplitude of breathing, and facilitates the improvement of the effect of radiation treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breathing control positioning device for radiotherapy of chest tumors. Background technique [0002] The basic requirement of precise tumor radiotherapy technology is to achieve "three highs and one low" in the final curative effect of tumors, that is, high precision, high dose, high curative effect and low damage. However, the respiratory movement of the lung organs causes the lung tumor to also undergo synchronous respiratory movement, which will constantly shift relative to the static position of the irradiation field, and the tumor location may exceed the irradiation area formulated in the radiotherapy plan. In order to overcome the influence of breathing movement on tumor radiotherapy, breathing control technology is often used in radiotherapy to improve the dynamic tumor cure rate and reduce the complications of surrounding normal tissues. [0003] Clinically, va...

Problems solved by technology

However, the low-temperature thermoplastic film is a consumable, with a low reuse rate and high cost. With the increase of time and the number of uses, the patient's body shape changes or the placement position changes. When repositioning, it will loosen or compress the chest and abdomen. degree, thereby reducing the therapeutic effect, for this reason, we propose a breathing control positioning device for chest tumor radiotherapy
