By effectively filtering impurities, particles and impure substances in drugs, it can not only improve the efficacy of drugs, but also reduce side effects and potential risks, providing patients with a safer and more efficient treatment experience. However, existing drug filters for the treatment of breast disease patients still have certain defects when used. During use, most filters are set as a single layer, and the overall filtering effect is insufficient, which affects the purity and therapeutic effect of the drugs. In addition, single-layer filters are prone to clogging, resulting in treatment interruption or drug waste.

[0003] In order to overcome the above-mentioned defects, the prior art 1 (application number 202022736399.3, Chinese patent application date 2020-11-16) is a series multi-stage filter, including a magnetic filter cartridge, a 60-mesh coarse filter cartridge, a 100-mesh coarse filter cartridge and a 200-mesh fine filter cartridge, one end of the magnetic filter cartridge is equipped with a feed pipe, and the feed pipe is connected to the magnetic filter cartridge, the magnetic filter cartridge is connected to the 60-mesh coarse filter cartridge through a connecting pipe, the 60-mesh coarse filter cartridge is connected to the 100-mesh coarse filter cartridge through a connecting pipe, the 100-mesh coarse filter cartridge is connected to the 200-mesh fine filter cartridge through a connecting pipe, a discharge pipe is installed on one side of the 200-mesh fine filter cartridge, and the discharge pipe is connected to the fine filter cartridge, the bottom of the 100-mesh coarse filter cartridge and the 200-mesh fine filter cartridge are both equipped with drain pipes, and the series multi-stage filter is convenient for liquid to enter from the magnetic filter end and go out of the fine filter 200 mesh, and the subsequent three filters are from coarse to fine filtration, There is also prior art 2 (Chinese patent with application number 201120301997.6 and application date 2011-08-18), a multi-stage filter, which belongs to the field of water treatment technology. Its structure consists of: a main tank body, a water inlet, a water outlet, a backwash inlet, a backwash drain outlet, a drain outlet, a butterfly valve, an endoscope and a manhole, pipe fittings, a discharge port, an aeration port, a stainless steel wedge-shaped filter layer, a quartz sand filter layer, an activated carbon filter layer and other components. The outside of the main tank body is fastened with a surrounding pipe fitting by a flange bolt, and a number of check valves are fixed in series on its right side. A stop valve is provided at the lower left end of the pipe fitting, an endoscope and a manhole are provided at the upper left corner of the main tank body, and a stainless steel wedge-shaped filter layer, a quartz sand filter layer, an activated carbon filter layer, a butterfly valve, a backwash drain outlet and a water inlet, a water outlet and a backwash inlet, a drain outlet are provided inside the main tank body from top to bottom, and the discharge port is provided on the lower left side of the main tank body.

[0004] Although the existing technology can improve the overall filtration efficiency, during the working process, filters are connected in series or multiple filter layers are set for processing.
