Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically refers to an airbag type medical protection device and its usage method. Background Art

[0002] Interventional radiology diagnosis and treatment has obvious advantages such as definite curative effect, small trauma, wide indications, and rapid postoperative recovery. It has now been widely used in the diagnosis and treatment of many clinical diseases, and its development momentum is rapid. However, most of the equipment used in interventional surgeries is an X-ray machine. The damage of X-rays to the examinees and medical staff objectively exists. When X-rays penetrate the human body, they can cause physical and chemical reactions of cells and lead to chromosomal structural aberrations, thereby causing damage to the human body. Moreover, this damage is a cumulative effect, especially more obvious to the growing and active tissues and organs such as the gonads, thyroid gland, bone marrow, and skin. As medical staff in interventional radiology diagnosis and treatment, they are inevitably exposed to X-ray radiation. The damage of X-rays to medical staff is often caused by its scattered rays. This type of scattered rays is mainly generated by part of the X-rays passing through an object / human body and reflecting when encountering an obstacle. The penetration power of this type of ray is limited, and the damage caused by it can be significantly reduced or even blocked through effective protection. Currently, in order to protect medical staff in interventional radiology diagnosis and treatment, generally, medical staff are equipped with a full set of radiation protection products such as special lead gowns, lead caps, lead face masks, and lead necklaces for "fully armed" protection. However, this inevitably causes inconvenience to the actions of medical staff. Currently, there are also some products on the market, such as lead isolation cloth or radiation protection clothing, etc., which are used to cover the non-irradiated parts of the examinees for shielding. However, their shielding effect often cannot be completely matched with the non-irradiated parts / irradiation positions, and they cannot block the divergence of X-ray scattered rays.
