A suction brush for bronchoscopy and lungs

Abstract

The invention relates to a liquid sucking brush for a bronchoscope and lungs. The brush comprises a brush handle (1), a brush rod (2), a brush head (3) and brush teeth (4). The brush is characterized in that a sucking pump port (5) is formed in the end portion of the brush handle (1), the brush head (3) and the brush teeth (4) are made of medical rubber, the brush head (3) is a cavity, a sucking hole (7) is formed in the brush head (3), a straw (8) is communicated with the sucking hole (7), the lower end of the straw (8) extends into the cavity of the brush head (3), and a one-direction valve (9) is arranged at the connecting position of the brush head (3) and the brush rod (2). The end portions of the brush teeth (4) are ball-shaped bodies (6). During use, the end portions of the brush teeth are ball-shaped and do not injure the lung tissues, and sputum, mucus, blood and the like which are brushed off can be sucked out by using a sucking pump. In addition, the bronchoscope lens can be wiped, and mucus on the lens can be sucked clean. Repeated pipe insertion is avoided, the pain of patients is reduced, and the examining accuracy, safety and efficiency of the bronchoscope is improved.

Description

Technical field [0001] The invention belongs to the technical field of medical equipment and equipment, and particularly relates to a liquid suction brush used for bronchoscopes and lungs. Background technique [0002] At present, lung lesions have the characteristics of variable locations and morphologies. When examining lung lesions with bronchoscopy, brushes should be used to brush the lung lesions, because the bristles are placed straight in [0003] Around the brush head, there is too much damage to the normal tissues that do not need to be brushed, which reduces the body's defense function and easily causes infection. In addition, the lens is often blurred due to the occurrence of sputum, mucus and bleeding in the treated area, which affects the continued operation of the diagnosis and treatment. The usual method is to repeatedly wash with saline through the operation hole of the fiberoptic bronchoscope or rub it locally. Or pull out the fiberoptic bronchoscope, wipe the le...
