Abstract

The invention discloses a device for extracting extractable materials from a polymeric biomedicine device. The device comprises a frame, four sliding rods are fixedly mounted in the frame along a vertical direction, the bottom ends of the sliding rods are fixedly mounted at four corners of the inner walls of the bottom side of the frame, a plurality of biomedicine device carriers are placed in theframe, four sliding holes are formed in four corners of biomedicine device carriers and slidably connected with the four sliding rods, a placing plate is slidably mounted in the frame and arranged onthe bottom side of the biomedicine device carriers, and four first through holes are formed in four corners of the top side of the placing plate and slidably connected with the sliding rods. According to the device, the biomedicine device carriers can be firmly placed, damage to the biomedicine device carriers caused by extrusion is prevented, positions of the biomedicine device carriers are conveniently limited, and falling of the biomedicine device carriers is prevented.

Description

technical field [0001] The invention relates to the field of biomedical technology, in particular to a device and a method for extracting extractable materials from polymerized biomedical devices. Background technique [0002] Polymerized biomedical devices, or biomedical devices that are the polymerization product of polymerizable chemical agents such as monomers, oligomers, macromers, and prepolymers, typically contain, for example, unreacted monomers, linear oligomers, macromolecular Extractable materials of monomers, prepolymers, or combinations thereof, which may be associated with adverse reactions in patients using biomedical devices. Accordingly, it is desirable, if not necessary, to extract these extractable materials from polymeric biomedical devices during their manufacture in order to reduce or prevent adverse reactions in patients. For example, in the manufacture of ophthalmic lenses, such as contact lenses, polymeric lenses are contacted by a liquid extraction...
