Abstract: Provided is a temperature-based dialysate regeneration device for regulating a temperature of dialysate discharged from a hemodialyzer to remove uremic toxins and waste therefrom, the temperature-based dialysate regeneration device including: a Joule-Thomson refrigerator, including a compressor, condenser, expander and evaporator, an adsorbent column, and a dialysate heat exchanger in which heat transfer occurs between dialysates. The refrigerant used for the JT refrigerator may be a mixture of two or more refrigerants to enhance the heat transfer generated by the latent heat in the evaporator and the condenser.

Abstract: Provided is a dialysate supply device and a blood dialyzing apparatus including the same. The dialysate supply device includes a flow controller controlling a dialysate flow, a supply pump supplying dialysate to a hemodialyzer, a recovery pump discharging dialysate from the hemodialyzer, a volume chamber storing dialysate, and a pressure-relief bypass maintaining dialysate pressure within a permissible range. The blood dialyzing apparatus includes the dialysate supply device, a blood tube, and a one-way valve disposed on the blood tube. The blood dialyzing apparatus can quickly change dialysate pressure in the hemodialyzer using the dialysate supply device having the flow controller, cylinder and piston, and increase mass transfer and hemodialysis efficiency. Also, the blood dialyzing apparatus may be miniaturized and lightened to provide a portable blood dialyzing apparatus because blood is transferred without using a blood pump.

Abstract: Provided is a multi-functional filter including a first filter and a second filter to purify a biological fluid, a housing defining an adsorption section outside of the first filter and the second filter, a flow partitioning connector connecting the first filter and the second filter, and a housing port allowing a fluid to flow through the adsorption section. The housing may comprise a wall, a first cap coupled to the first filter at one end of the wall along a longitudinal direction, and a second cap coupled to the second filter at the other end of the wall along a longitudinal direction. The multi-functional filter according to the present invention in which dialysis, adsorption, and plasma separation or ultrafiltration are integrated to purify blood or dialysate and the internal flow is facilitated may provide a blood purifying apparatus that simplifies the whole apparatus, provides convenience in installation and use, and reduces a treatment cost.

Abstract: Provided is a dialysate supply unit and a blood dialyzing apparatus including the dialysate supply unit for supplying dialysate of a dialysate tank to a hemodialyzer and collecting dialysate passing through the hemodialyzer in an effluent tank. The dialysate supply unit includes a dialysate pump, an effluent pump, a first flow-blocking valve, a second flow-blocking valve, and a flow-blocking valve driver. The dialysate pump connects the dialysate tank and the hemodialyzer and the effluent pump connects the hemodialyzer and the effluent tank. The first flow-blocking valve alternately blocks a dialysate outflow tube connecting the hemodialyzer and the dialysate pump and an effluent inflow tube connecting the hemodialyzer and the effluent pump. The second flow-blocking valve alternately blocks a dialysate inflow tube connecting the dialysate pump and the dialysate tank and an effluent outflow tube connecting the effluent pump and the effluent tank. The flow-blocking valve driver drives the flow-blocking valve.
