Endoscopic lower respiratory tract flushing device

Technical Field

The utility model relates to a medical apparatus, in particular to a fiber bronchoscope lower respiratory tract flushing pipe, an endoscope thereof and a fiber bronchoscope respiratory tract terminal cleaning device based on the content, and particularly relates to an endoscope lower respiratory tract flushing device.

Background

The bronchoendoscope is generally used in bronchoexamination, sputum suction and cleaning operations, and has the functions of removing sputum plug and sputum and cleaning the airway of a patient, and the common sputum suction operation mode is that water is firstly flushed, and then liquid suction operation is carried out. The flushing mode is that water flow is directly poured forward. The flushing and sputum suction share a common channel. This traditional bronchofiberscope airway cleaning (sputum aspiration) method has the following clinical pain points: 1) For thick or dry sputum adhered to bronchial mucosa, the sputum is difficult to clean or suck out quickly, the ventilation function is seriously affected, and even the life of a patient is endangered; 2) Its product structure and handling properties are insufficient to remove inflammatory secretions or foreign bodies from the respiratory tract terminals; 3) The traditional fiber bronchoscope has the advantages that the product design can only adopt a working mode of flushing and then sucking, the respiratory tract can not be cleaned quickly, the time consumption is long, and the operation risk is obviously increased; 4) When the operation is performed, the water is flushed and then the liquid is absorbed, and the flushing and the liquid absorbing share one lumen, so that the sputum suction pipeline is easy to pollute, and potential safety hazards such as suffocation of patients are easy to cause. Therefore, the existing products are difficult to thoroughly and quickly clean the adhered sputum and the deep peripheral bronchus sputum, and have large operation risks and relatively waste time and labor. Therefore, the clinical urgent need innovates and designs a device which can wash and clean the mucous membrane of the respiratory tract and inhale phlegm fast and effectively, and can clear the peripheral secretion of the respiratory tract through the fast siphon action. The Chinese patent ZL202120352400.4 solves the problems well, and the applicant finds that the flushing pipe and the liquid suction pipe used in the patent are both fixed in an endoscope operation channel, the outer pipe of the endoscope is used as an infusion channel, flushing can only be carried out simultaneously in the liquid spraying process, and the spraying flushing can not be carried out at fixed points and orientations on the fine peripheral bronchus. Inconvenient use, and can not realize peak-shifting flushing and cleaning for viscous sputum, thereby achieving the effect of accurately positioning and flushing the bronchus at the fine tip. And at the same time the problem of increasing the operation time must be solved.
