Abstract
The present disclosure includes systems and methods for hemodialysis, such as including a first dialysis module and an auxiliary module detachably connectable to the first dialysis module. The first dialysis module can include a dialyzer, a blood circuit, a dialysate circuit, and a sorbent. The auxiliary module can include an ultrafiltrate collector operably couplable to the dialysate circuit for removing excess fluid therefrom.
Claims19
A system for hemodialysis comprising:
- a first dialysis module comprising:
- a dialyzer;
- a blood circuit configured to receive blood from a patient, circulate the blood through the dialyzer, and return cleaned blood to the patient;
- a dialysate circuit configured to circulate dialysate through the dialyzer and remove impurities from the blood;
- a first sorbent for removing toxins from the blood;
- and
- a first case enclosing the dialyzer, the blood circuit, the dialysate circuit and the first sorbent;
- an auxiliary module detachably connectable to the first dialysis module, the auxiliary module comprising:
- an ultrafiltrate collector operably couplable to the dialysate circuit for removing excess fluid therefrom;
- an ultrafiltrate pump;
- and
- a second case enclosing the ultrafiltrate collector and the ultrafiltrate pump;
- a fluid line extending through the first case and the second case to connect the ultrafiltrate pump and the dialysate circuit;
- and
- a connector element disposed in the fluid line to allow a user to release the auxiliary module from the first dialysis module without interrupting flow in the dialysate circuit.

- a first dialysis module comprising:
- a dialyzer;
- a blood circuit configured to receive blood from a patient, circulate the blood through the dialyzer, and return cleaned blood to the patient;
- a dialysate circuit configured to circulate dialysate through a loop including the dialyzer to remove impurities from the blood;
- a first sorbent in the dialysate circuit for removing toxins from the blood;
- a pump for the blood circuit and the dialysate circuit;
- and
- a battery for supplying power to the pump;
- an auxiliary module detachably connectable to the first dialysis module, the auxiliary module comprising an ultrafiltrate collector operably couplable to the dialysate circuit for removing excess fluid therefrom, wherein the auxiliary module can be disconnected form the dialysate circuit without disrupting flow through the loop;
- and
- a second dialysis module detachably connectable to the first dialysis module, the second dialysis module comprising:
- a power cord for supplying power to the pump alternatively with the battery;
- one or more hook-ups for connecting to the dialysate circuit so that the loop is expanded and bypasses the first sorbent;
- and
- a second sorbent for removing toxins from the blood.
