Alveolar lavage fluid collector

Abstract

The invention relates to the field of medical instruments, in particular to an alveolar lavage fluid collector. The alveolar lavage fluid collector comprises an outer single-cavity pipe with an opening in the tail end, an inner single-cavity pipe, a water suction pipe, a perfusion pipe and a retractable mechanism control device; the inner single-cavity pipe is disposed in the outer single-cavity pipe, a cavity is formed between the inner single-cavity pipe and the outer single-cavity pipe, the top of the outer single-cavity pipe is used for being inserted into the body of a patient, the innersingle-cavity pipe penetrates through the tail end of the outer single-cavity pipe to be connected to the retractable mechanism control device, and the water suction pipe is disposed in an inner cavity of the inner single-cavity pipe; one end of the water suction pipe sequentially penetrates through the inner single-cavity pipe and the outer single-cavity pipe and is communicated with the top of the outer single-cavity pipe. The end, away from the outer single-cavity pip, of the water suction pipe sequentially penetrates through the inner single-cavity pipe and the retractable mechanism control device and extends out of the retractable mechanism control device to be communicated with a negative pressure collector.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an alveolar lavage fluid collector. Background technique [0002] Bronchoalveolar lavage can directly obtain inflammatory immune effector cells in the lung, and it is a relatively safe and useful examination method for exploring the local immunopathological process of the lung. For some lung diseases, especially diffuse interstitial lung diseases (such as idiopathic pulmonary fibrosis, sarcoidosis, alveolar proteinosis, etc.), lung tumors, and lung infections, bronchoalveolar lavage has been used It has become an important detection method to assist clinical diagnosis and judge prognosis. However, the collection of qualified bronchoalveolar lavage fluid is affected by many factors, such as: suction negative pressure, lavage volume, recovery volume, and the length of time the lavage fluid stays in the lungs. The existing alveolar perfusion fluid collector for lavage fluid is ver...

AI Technical Summary

Problems solved by technology

The existing alveolar perfusion fluid collector for lavage fluid is very simple to make, but there are problems such as being unable to block the bronchial opening, unable to reach the tertiary bronchi and below, the recovery rate of the lavage fluid is low, and the irrigation and recovery cannot be performed at the same time, so There is an urgent need for an efficient alveolar fluid collector
