Device for collecting alveolar lavage fluid

Abstract

The invention provides a device for collecting alveolar lavage fluid, which comprises an intubation tube, wherein a perfusion pipeline and a water absorption pipeline are fixedly inserted in the intubation tube; a sealing membrane is fixedly arranged at the position of the outer side of the intubation tubeclose to the left end; a plugging block is rotatably connected in the intubation tube and positioned in the sealing membrane; a slip ring is slidably inserted in the intubation tube and positioned on the right side of the plugging block; and an ejector rod corresponding to the plugging blockis fixedly connected to the left side of the slip ring. The slip ring and the ejector rod move to the left by rotating a knob, and making the blocking block rotate, so that the sealing membrane is opened, a bronchial tract is blocked, spilling liquid is prevented from overflowing and flowing back during lavage, the utilization rate of lavage liquid and the lavage effect are improved, lavage liquidcan be recovered more completely, and the accuracy of a subsequent lavage liquid detection analysis result is further improved; and by setting the blocking structure to be adjustable, lavage liquid can be better adapted to specific conditions of a patient, and damage to the patient due to excessive blocking is avoided.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a device for collecting alveolar lavage fluid. Background technique [0002] Alveolar lavage is currently the main method for the treatment of PAP. Its operation process is to insert a cannula into the patient's bronchi, inject normal saline lavage fluid into the alveoli for lavage, and then suck out the lavage fluid for detection and analysis. The collection of alveolar lavage fluid is affected by many factors, among which the amount of lavage and recovery of the lavage fluid are also important factors. However, the current equipment for collecting alveolar lavage fluid is simple in structure and does not have a blocking device, resulting in When pouring, the lavage fluid overflows and flows back from the gap between the intubation tube and the bronchi, which makes it difficult to control the amount of lavage, and also affects the collection of the lavage fluid. Many l...
