Description

Technical Field

[0001] This utility model relates to the field of animal experimental technology, specifically a simple experimental porcine bronchoalveolar lavage device. Background Technology

[0002] Acute lung injury (ALI) is a hypoxic respiratory failure caused by multiple factors, often progressing to acute respiratory distress syndrome (ARDS). This disease has a high morbidity and mortality rate, making its pathogenesis a subject of great interest. Many researchers have explored its pathophysiological processes by constructing animal models. In experimental research, bronchoalveolar lavage is a widely used technique, particularly important in inducing acute lung injury models in experimental pigs.

[0003] However, existing bronchoalveolar lavage has shortcomings in practical use. In particular, it requires the use of a bronchoscope during lavage, which is an invasive procedure. The bronchoscope is prone to shaking when inserted into the trachea, which can damage the bronchial wall. In addition, it does not have a suction function, so other suction equipment needs to be found, which limits its applicability.

[0004] Therefore, it is particularly important to design a simple experimental porcine bronchoalveolar lavage device for inducing an acute lung injury model after lavage. This device should be easy to operate, minimize damage to the bronchial wall, and have aspiration function to improve the efficiency and accuracy of the experiment. By introducing modern manufacturing equipment, the complexity of the experimental operation can be significantly reduced, time can be saved, and efficiency can be improved. The design and implementation of such a device will provide strong support for the construction of an acute lung injury model. Utility Model Content
