Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical product processing, in particular to a filling device used for embolic microsphere processing. Background Art
[0002] Embolic microspheres are a type of medical embolic material, usually tiny, spherical solid particles made of polymer materials with good biocompatibility. In medical treatment, embolic microspheres are usually used to block or reduce blood flow in abnormal blood vessels. They are usually delivered into target blood vessels using a catheter through minimally invasive surgery. Once the microspheres reach the designated location, they will remain in the blood vessels, causing local blood flow interruption, and then leading to ischemia, necrosis or shrinkage of the target tissue, thereby achieving the treatment goal.
[0003] When embolic microspheres are used clinically, they are generally delivered precisely to the lesion site through syringes and catheters to achieve the therapeutic effect. In order to ensure the smooth flow of the embolic microspheres in the syringe, solutions such as saline are generally added to the syringe. Therefore, during the processing of the embolic microspheres, the embolic microspheres and solutions such as saline need to be packaged into the syringe together. The commonly used equipment is a filling machine, which fills the embolic microspheres and saline into the syringe through a filling head. After the syringe is packaged, it can be used in subsequent clinical use. Depending on the size of the embolic microspheres, the selected syringe size is also different. When filling, the current filling equipment is prone to solution overflow when filling syringes of different sizes, resulting in insufficient injection volume in the later stage.
