Description

Technical Field

[0002] In some vascular abnormalities or malignant tumor diseases, doctors will inject a spherical, tiny solid particle into the abnormal blood vessel, thereby blocking the blood supply to a specific area to achieve the purpose of treatment. The solid particles implanted into the patient's abnormal blood vessels are called embolic microspheres, which are essential medical supplies for the treatment of some diseases. The sizes of embolic microspheres vary for different diseases or different people's blood vessels. When treating specific diseases, it is necessary to select embolic microspheres of appropriate sizes in a targeted manner in order to achieve the effect of blocking blood supply. Therefore, manufacturers of embolic microspheres generally produce embolic microspheres of various sizes. After the production of embolic microspheres is completed, it is necessary to ensure that their size meets the production requirements. Therefore, the embolic microspheres need to be screened to ensure that the embolic microspheres have an accurate and consistent particle size. Commonly used microsphere screening equipment includes vibrating screens, drum screens, centrifugal screens, etc. The microspheres are graded and screened in the form of physical screens. However, the use environment and storage environment of embolic microspheres are both in liquids. Most ordinary screenings directly screen the embolic microspheres. The embolic microspheres will adhere to each other, affecting the normal screening. In addition, since it is impossible to simulate the liquid environment in which the embolic microspheres are located, the embolic microspheres are not screened while flowing, and accurate screening results cannot be obtained.
