Visual double-lumen bronchial catheter with sampling device and use method of visual double-lumen bronchial catheter

Abstract

The invention discloses a visual double-lumen bronchial catheter with a sampling device and a use method thereof. The visual double-lumen bronchial catheter comprises a main tube, a main tracheal balloon, a bronchial balloon, a guide wire, a one-way valve, an indication balloon, an inflation tube, an operation interface, a guide wire, a visual channel sealing joint, a camera, a sampler, a four-way valve, a first tracheal connecting tube, a tracheal tube joint, a connecting piece and a rotating shaft, the method comprises the steps of 1, inserting a main pipe; 2, inflating the air bag; 3, inflating the main pipe; 4, medicine injection; step 5, internal observation; step 6, taking a focus sample; compared with an existing double-lumen bronchial catheter, the double-lumen bronchial catheter has the advantages that the sampler is arranged beside the camera, so that visual sampling is realized without other equipment; according to the invention, the trouble of repeated use of the bronchofiberscope and the risk of cross infection are avoided; the designed flow limiting block can adjust the flow of injected medicine, and medicine injection can be controlled according to the specific illness state of a patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a visual double-lumen bronchial catheter with a sampling device and a method for using the same. Background technique [0002] In clinical thoracic surgery and lung surgery, it is often necessary to separate the patient's lungs, which requires the use of a double-lumen bronchial catheter to ensure lung ventilation while separating the lungs and avoiding lung secretions during the operation , interstitial fluid or blood into another lung, causing infection to the lung that is not in operation. The existing double-lumen bronchial catheter has a simple structure and needs to be assisted by a laryngoscope and a fiberoptic bronchoscope when used. The endoscope needs to be disinfected and cleaned after use, and if the disinfection is not thorough, it is easy to cause cross-infection; the existing double-lumen bronchial catheter needs to use additional sampling equipment when ...

The existing double-lumen bronchial catheter has a simple structure and needs to be assisted by a laryngoscope and a fiberoptic bronchoscope when used. The endoscope needs to be disinfected and cleaned after use, and if the disinfection is not thorough, it is easy to cause cross-infection; the existing double-lumen bronchial catheter needs to use additional sampling equipment when taking lesion samples, and the operation steps are many and difficult; the existing double-lumen bronchial catheter Bronchial catheters cannot flexibly control the flow of drugs when infusing drugs to the lungs, which is not conducive to the control of patients' conditions
