A kind of respiratory secretion collection bottle under bronchoscope

Abstract

The invention discloses a lower-respiratory-tract secretion collecting bottle for a bronchoscope. The lower-respiratory-tract secretion collecting bottle comprises a bottle body, wherein the top of the bottle body is communicated with an air extracting pump through an air suction pipe; the top of the bottle body is communicated with a suction head through a collecting pipe; the air extracting pump is supplied with power by a power supply; the on and the off of the air extracting pump are controlled by a control mechanism. According to the lower-respiratory-tract secretion collecting bottle, when the suction force is excessively high, the pressure in the suction head is suddenly reduced; as a cavity is not communicated with the interior of the suction head, air pressure is higher relative to a through hole; an obstructing block is oppressed to cut off the through hole; the damage to a respiratory tract of a patent as the suction force is too high can be effectively avoided; when a pipeline of a device is blocked, as the air extracting pump continuously works, the air pressure in the bottle body is continually decreased relative to that of an external environment; a sliding block in a sleeve is moved towards a right end; under the traction of a cable rope, an upper conductor sheet and a lower conductor sheet overcome the action of the elastic force of a spring hinge and are not in contact any more; the power supplied to the air extracting pump is disconnected by the power supply; the further damage to the inner wall of the respiratory tract is effectively avoided.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a bronchoscopic respiratory secretion collection bottle. Background technique [0002] The bronchoscope is suitable for observation of lung lobe, segmental and subsegmental bronchial lesions, biopsy sampling, bacteriological and cytological examination, and can be used for photography, teaching and dynamic recording with the TV system. The bronchoscope is equipped with a biopsy sampling mechanism, which can help to detect early lesions, and can carry out internal surgical operations such as polyp removal. It is a good precision instrument for bronchial and lung disease research, postoperative inspection, etc. During the operation, the patient The lungs and tracheal lesions of patients will produce a large amount of mucus-like secretions mixed with exfoliated epithelial cells. In order to facilitate the operation, a collection bottle is needed to suck the secretions out ...

AI Technical Summary

Problems solved by technology

However, in this solution, the drainage tube is directly used to absorb the respiratory secretions. Since the secretions are viscous, the absorption force is relatively large, and it is easy to cause damage to the mucous membrane of the inner wall of the respiratory tract due to the strong suction. Not only that, when the device is blocked by mucus At this time, the device continues to work, not only damaging the equipment, but also causing further damage to the patient's airway
