Returning the Blood to the Patient Manually
To return the blood manually:
1. Remove the bloodline from venous line clamp. If you are performing single-needle
dialysis, remove the pump segment from the single-needle pump.
2. Replace saline bag with a fresh bag if necessary.
3. Using a hemostat, clamp and disconnect the arterial bloodline directly above the saline
“T”.
4. Open the saline line clamps and rinse the blood in the tubing below the saline “T” back to
the patient. When the blood in the line has been rinsed back to the patient, close the
saline line clamps.
5. Clamp the arterial bloodline directly under the saline “T”. Remove the clamp on the
bloodline above the saline “T” and open the saline line clamps.
6. Open the pump door and flip the rotor latch outward (see Figure 55 #1).

7. Align the slot and the spindle on the crank handle with the rotor latch and hole as shown
in Figure 55 #2 above.
8. Slide the crank handle in as far as it will go. The crank latch will protrude slightly from
the crank handle (see Figure 55 #3).
9. Rotate the crank clockwise and rinse back the blood with the saline according to unit
protocol. The blood should be returned under strict visual control.
Warning! Carefully observe the venous chamber and bloodline for the presence of air. Be
sure no air will be infused into the patient.
10. Clamp the arterial and venous bloodlines and the patient’s arterial and venous access
lines, and aseptically disconnect them.
Manual Circulation
To circulate the blood manually:
1. Remove venous line from clamp. Be sure no air will be infused into the bloodline. If you
are performing single-needle dialysis, remove the pump segment from the single-needle
pump.
