[0002] Negative pressure drainage device is a widely used device in the medical field, mainly used to help patients effectively drain body fluid, pus or blood. Its core working principle is to use the negative pressure principle to guide the patient's body fluid into the collection bottle through the drainage tube to achieve the purpose of cleaning and drainage. The negative pressure drainage device has a delicate structure and is usually composed of a transparent collection bottle, a soft drainage tube, a negative pressure regulator and a sealing cover. Each part works together to ensure the safety and effectiveness of the drainage process.
