Abstract

A system for performing fluid administration on a patient, the system including a flexible membrane forming a valve of a port having a valve seat, and an actuator having an actuator head, wherein the flexible membrane includes a membrane actuator clip configured to removably connect to the actuator head, the connection between the membrane actuator clip and the actuator head allowing the actuator to push the flexible membrane towards the valve seat to close the valve, and to pull the flexible membrane away from the valve seat to open the valve.

Claims

1. A system for performing fluid administration on a patient comprising:

a removable and disposable cartridge having a flexible membrane forming a plurality of valves, each of the valves including a membrane actuator clip; and

a cartridge loader having a plurality of valve actuators, each of the valve actuators having an actuator head associated with a corresponding membrane actuator clip,

wherein the disposable cartridge is configured to be connected to and removed from the cartridge loader such that each membrane actuator clip is (i) configured to connect to a corresponding actuator head in an activated position, the connection between the membrane actuator clips and the actuator heads allowing a push movement and a pull movement of the membrane by the valve actuators, and is (ii) configured to be removed from the corresponding actuator head to remove the disposable cartridge from the cartridge loader.

2. The system according to claim 1, wherein each actuator head of the plurality of valve actuators includes a plunger that is clipped into a cavity of the corresponding membrane actuator clip.

3. The system according to claim 2, wherein a length of the plunger to be inserted into the cavity of the corresponding membrane actuator clip is longer than a maximal displacement of the plunger.

4. The system according to claim 1, wherein the flexible membrane is formed such that in a rest position, the plurality of valves are closed.

5. The system according to claim 1, wherein the plurality of valves are configured to tightly close a corresponding valve port when the membrane moves downwardly.

6. The system according to claim 1, wherein the disposable cartridge includes a channel that is in fluid connection with at least one of the plurality of valves, the flexible membrane forming a fluid seal with the disposable cartridge along a frame of the flexible membrane.

7. The system according to claim 6, wherein the fluid seal is formed by a flange of the flexible membrane and a groove of the disposable cartridge configured to receive and hold the flange.

8. The system according to claim 1, wherein the disposable cartridge includes a rigid plate, the rigid plate covering the flexible membrane,

wherein the rigid plate includes a plurality of openings at locations of the plurality of valves, respectively, to allow the plurality of valve actuators to engage with the plurality of valves, respectively.

9. The system according to claim 1, wherein the disposable cartridge includes a pressure sensor cavity and the flexible membrane includes a pressure sensor area.

10. A disposable cartridge for performing a dialysis treatment to a patient comprising:
