Telescopic airtight assembly special for bronchoscope

Abstract

The invention relates to a telescopic airtight assembly special for a bronchoscope, and belongs to the technical field of medical apparatuses. The telescopic airtight assembly special for the bronchoscope comprises a silica gel sleeve, a telescopic sleeve and a sealing sleeve, wherein a bronchoscope body of the bronchoscope sequentially passes through the inner part of the silica gel sleeve, the inner part of the telescopic sleeve and the inner part of the sealing sleeve; a clamping spring which is arranged at the outer periphery of the silica gel sleeve can tightly clamp the bronchoscope body, silica gel sleeve elastic valves are arranged on the inner side periphery, near the lower end opening, in the silica gel sleeve, and the lower end opening of the sealing sleeve is fixed to a steppedshaft of a dual-cavity bronchial cannula accessory in a sealing manner; and two ends of the telescopic sleeve are respectively fixed to the outer periphery of the lower end opening of the silica gelsleeve and the outer periphery of the upper end opening of the sealing sleeve in a sealed manner. In the operating process of the bronchoscope, the airtight assembly cannot enable a breathing apparatus to leak air to cause inspection suspension, the time of inspection of doctors can be sufficient, and authenticity of an inspection result is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a special telescopic airtight assembly for bronchoscopes. Background technique [0002] The bronchoscope is suitable for the observation of lung lobes and bronchial lesions, and can be used for biopsy sampling, bacteriological and cytological examination, and can be used for photography, teaching and dynamic recording with the TV system. The existing bronchoscope is equipped with a biopsy sampling mechanism, which can help to detect early lesions and carry out internal and external operations such as polyp removal. It is a good precision instrument for the research of bronchial and lung diseases and postoperative examination.

AI Technical Summary

Problems solved by technology

[0003] When the existing bronchoscope is inserted into the silicone membrane on the accessory of the double-lumen bronchial intubation, when encountering bronchoscopes with different diameters, the opening is small and the frictional resistance is large, and the insertion and withdrawal cannot be smoothly performed. The silicone membrane must be cut into symmetrical pieces with a blade. Four flaps, although it can be inserted, but when pulling or twisting during the examination, because the ventilator is connected to the double-lumen bronchial intubation attachment, it is very easy to leak air, and the patient will interrupt the examination due to hypoxia, leaving the doctor with an effective The examination time is very short and rushed, which is not conducive to clear and accurate examination results, resulting in misdiagnosis
