Title: MEDICAL LIQUID FILTERING DEVICE
Abstract:
A medical liquid filtering device, comprising a tank body (10), a first screen (20) and a second screen (30). The tank body (10) is provided with a feed port (11) and a liquid-discharge port (12). Both the first screen (20) and the second screen (30) are provided inside the tank body (10), the first screen (20) being a cover structure. The middle portion of the second screen (30) is provided with an opening area (31), and the second screen (30) contacts or is connected to the end of the first screen (20), having a cover opening (21). The outer periphery of the second screen (30) contacts and fits with the inner side wall of the tank body (10). The cover structure is provided on and covers the opening area (31). According to the medical liquid filtering device, the screen in the tank body (10) is divided into a first screen (20) and a second screen (30) and designing the first screen (20) to be a cover structure. This way, as compared with a traditional screen, the first screen (20) and the second screen (30) have a larger area in contact with the medical liquid in the tank body (10), and medical residues are less prone to accumulate on the side wall of the cover, thereby preventing medical residues from blocking the first screen (20), such that the liquid discharging speed is faster than that of a traditional medical filtering device, and the medical liquid filtering efficiency is higher.
