Description

Technical Field

[0001] This utility model relates to the field of medical experimental equipment, specifically a tool for rat tracheal instillation that is easy to use and quick to apply. Background Technology

[0002] Tracheal instillation is an important technique for studying the damage of exogenous chemicals to the respiratory system. It is also a crucial means of constructing lung injury models and exploring interventions for respiratory diseases. Tracheal instillation allows for quantitative studies of the effects of exogenous chemical intake on animal lungs and avoids cross-exposure. Currently, tracheal instillation is divided into two types based on whether the trachea is exposed: exposed and non-exposed. Exposed tracheal instillation requires cutting the skin and muscles of the rat's neck to expose the trachea, inserting a tube, and then using a syringe to precisely instill the chemical. Non-exposed tracheal instillation is a non-invasive procedure, but it has high operational requirements and a low success rate. Existing non-exposed tracheal instillation tools typically involve inserting an indwelling needle after the rat's glottis has opened until the resistance is high. During the procedure, the hand must remain stable at all times. To prevent damage to the rat's pharynx from the indwelling needle, the procedure must be performed slowly. Such instillation tools are not convenient for rapid use, thus increasing the operation time. Utility Model Content
