The present invention provides a filter device having a water inlet and a water outlet. The filter device comprises a filter cabin () and a filter core (). The water inlet and the water outlet are disposed on one end of the filter cabin (). The filter cabin () comprises a cabin body, a cabin door and a gear driving assembly. The cabin body disposes a gear-mounting slot for receiving and holding the gear driving assembly. The filter core has an end portion, which is fluidly connected with the water inlet and the water outlet. The filter core disposes a driving rack on an outside surface thereof. The driving rack is engaged with the gear driving assembly. The filter device of the present invention can quickly replace the filter core () by the special design of the filter core, the filter cabin () and the gear driving assembly.

A bondable blood-friendly polymer is a terpolymer or a quadripolymer at least formed by polyethylene glycol alkyl ether acrylate or polyethylene glycol alkyl ether methacrylate (I), and zwitterionic acrylic ester or zwitterionic methacrylic ester (II), and acrylic acid or a methacrylate derivative with an epoxypropyl group, an isocyanate group, a trialkoxy silane, a hydroxyalkyl group, a propargyl group or a quaternary ammonium group (III). In the present invention, the blood-friendly polymer with a potentially-bondable group has the following advantages: although the water insolubility thereof is implemented by using the hydrophobicity physical effect of an existing higher alkyl acrylate linkage, the blood friendliness of a coating is reduced due to the existence of a great number of hydrophobic chain links in the polymer; and a physical coating is slowly desolventized from the surface to be ablated in the application process of the physical coating. A disclosed bondable blood-friendly polymer coating not only can overcome these defects, but also can improve the blending property thereof. Disclosed are composition, a structure and a preparation method of the bondable blood-friendly polymer.
