Abstract
Extracorporeal blood treatment systems including air purge control capabilities are disclosed. An example extracorporeal blood treatment system may include an extracorporeal blood pathway between a venous side of the heart and an arterial side of the heart, an air trap positioned along the blood pathway, a first sensor positioned adjacent the bubble trap and a second sensor positioned adjacent the bubble trap. Further, a first signal sent by the first sensor is configured to activate air removal from the air trap and a second signal sent by the second sensor is configured to deactivate air removal from the air trap.
Claims20
An extracorporeal blood treatment system, comprising:
- an extracorporeal blood pathway between a venous side of the heart and an arterial side of the heart;
- an air trap positioned along the blood pathway;
- a first sensor positioned adjacent the bubble trap;
- a second sensor positioned adjacent the bubble trap;
- and
- wherein a first signal sent by the first sensor is configured to activate air removal from the air trap;
- wherein a second signal sent by the second sensor is configured to deactivate air removal from the air trap.
An extracorporeal blood treatment system, comprising:
- an extracorporeal blood pathway between a venous side of the heart and an arterial side of the heart;
- an air trap positioned along the blood pathway;
- a first sensor positioned adjacent the air trap;
- a second sensor positioned adjacent the air trap;
- and
- an air removal element coupled to the air trap;
- a control unit in communication with the first sensor, the second sensor and the air removal element;
- wherein the air removal element is configured to activate after receiving a first signal from the first sensor;
- wherein the air removal element is configured to at least partially deactivate after receiving a second signal from the second sensor.
An extracorporeal blood treatment system, comprising:
- an extracorporeal blood pathway between a venous side of the heart and an arterial side of the heart;
- an air trap positioned along the blood pathway;
- a first sensor positioned upstream of the air trap;
- a tubing pathway extending between the air trap and a roller pump;
- a second sensor positioned along the tubing pathway;
- and
- a control unit in communication with the first sensor, the second sensor and the roller pump;
- wherein the first sensor is configured to send a first signal to the control unit, and wherein the first signal corresponds to an amount of air present in blood flowing within the blood pathway;
- wherein the second sensor is configured to send a second signal to the control unit, and wherein the second signal corresponds to an amount of air present in the tubing pathway;
- wherein the roller pump is configured to activate after receiving a third signal from the control unit, and wherein the third signal corresponds to the first signal received from the first sensor;
- wherein the roller pump is configured to at least partially deactivate after receiving a fourth signal from the control unit, and wherein the fourth signal corresponds to the second signal received from the second sensor.
