Blood purifier device and method
First Claim
1. A gravity fed blood purifier device for removing waste particles from red blood cells, the blood purifier device comprising:
- a first end plate and a second end plate;
a first cylindrical tube positioned between the first end plate and the second end plate;
a porous tube positioned between the first end plate and the second end plate and within the first cylindrical tube;
an inlet that provides unpurified red blood cells into the porous tube;
an electrode and a voltage source configured to maintain a negative potential across the porous tube to repel red blood cells;
wherein the blood purifier device is configured to cause the waste particles to pass through pores of the porous tube and the red blood cells to be maintained within the porous tube such that the waste particles are removed from the first cylindrical tube through an exit port and purified red blood cells are provided to an outlet during operation of the blood purifier device.

Abstract
Embodiments of the invention provide a gravity-fed blood purifier device for removing waste particles from blood. In one embodiment, the blood purifier device includes a pair of end plates and a first cylindrical tube located between the end plates. The blood purifier device also includes a porous tube contained within the space defined by the first cylindrical tube. An inlet provides unpurified red blood cells into blood purifier device. An electrode generates a negative potential across the porous tube to repel red blood cells so that the waste particles pass through the porous tube and the red blood cells do not. An outlet can be coupled to one of the end plates to receive the purified red blood cells.

13. A gravity-fed blood purifier device for removing waste particles from red blood cells, the blood purifier device comprising:
-
a first plate having an inlet configured to provide unpurified red blood cells; a second plate coupled to the first plate; a porous sheet coupled between the first plate and the second plate; an electrode and a voltage source configured to maintain a negative potential across the porous sheet to repel red blood cells; wherein the blood purifier device is configured to separate the waste particles from healthy red blood cells by causing the waste particles to pass through pores of the porous sheet to an exit port and the purified red blood cells to pass adjacent to the porous sheet to an outlet coupled to the first plate during operation of the blood purifier device. - View Dependent Claims (14, 15, 16, 17, 18)

19. A gravity-fed blood purifier device for removing waste particles from red blood cells, the blood purifier device comprising:
-
a housing component having an inlet configured to provide unpurified red blood cells into the housing component; an outlet configured to expel purified red blood cells from the housing component; and an exit port configured to drain waste particles out of the housing; a porous component inside the housing component; and an electrode and a voltage source configured to maintain a negative potential across the porous component to repel red blood cells; wherein the blood purifier device is configured to separate the waste particles from healthy red blood cells such that the waste particles pass through pores of the porous component to the exit port and the purified red blood cells are repelled by the porous component and expelled through the outlet during operation of the blood purifier device. - View Dependent Claims (20, 21)
