Single-lung lobe spray device used in combination with bronchoscope

Abstract

The invention relates to a single-lung lobe spray device used in combination with a bronchoscope. The device includes a medium loading unit, a communicating tube and a medium spray unit. The medium loading unit is connected with the spray unit through the communicating tube; the medium loading unit automatically or manually pushes and injects a medium for conveying quantitatively through an electronic numerical-control setting program; during use, the bronchoscope is inserted into the trachea under the observation of a bronchoscope lens, and a spray end of the single-lung lobe spray device isinserted from an inlet of a bronchoscope embedding passage and extends out of the bronchoscope to be inserted into the front end of the tube. After the device reaches a designated position in one lunglobe, the loading unit is started, and the medium is pushed to the spray unit and partially atomized through micropores. The device can achieve insertion into small bronchi and one lung lobe and partially atomize the medium, the operation technique of the bronchi and partial lung lobes is expanded, and the application of the bronchoscope to the lung lobes of animals and infants is also expanded.

Description

technical field [0001] The invention belongs to a medical device, and in particular relates to a single-lobe lung spray device. The device is used in conjunction with a bronchoscope, can enter the single-lobe lung through the bronchus, and realize local spray intervention, and is used for medical experiments and treatments. Background technique [0002] Bronchoscopy-mediated technology is widely used in experimental research and treatment of respiratory diseases such as bronchitis, asthma, pulmonary fibrosis, chronic obstructive pneumonia, and lung tumors. Existing bronchoscopes can enter bronchi with an inner diameter greater than 2-3 mm, but it is difficult to intervene in bronchial branches with an inner diameter less than 2 mm. Therefore, its application to the relatively small bronchi of the lungs of human infants and experimental animals has great limitations, especially the inability to enter each single lobe lung. Nebulized administration is widely used in the inter...
