Controlling of multiple pumps
First Claim
1. A method for operating at least two pumps, comprising:
- activating a first pump using a multiple channel adjustment apparatus configured to operate with the first pump to provide nonzero fluid pressure at a first nonzero fluid pressure level; and
transitioning from the first pump providing nonzero fluid pressure at the first nonzero fluid pressure level to a second pump providing nonzero fluid pressure at a second nonzero fluid pressure level using the multiple channel adjustment apparatus;
wherein said transitioning comprises a gradual transitioning from the first nonzero fluid pressure level from the first pump toward the second nonzero fluid pressure level from the second pump while maintaining a relatively constant fluid pressure level within a surgical region of a patient.

Abstract
An apparatus for controlling vacuum pressure is provided. The apparatus includes a multiple axis controller, such as a dual axis footpedal, and a processing apparatus, such as an instrument host running software, configured to receive multiple axis data from the multiple axis controller. The apparatus also includes a first pump configured to provide nonzero fluid pressure at a first nonzero fluid pressure level based on a first axis state of the multiple axis controller and a second pump configured to provide nonzero fluid pressure at a second nonzero fluid pressure level based on a second axis state of the multiple axis controller. The processing apparatus causes switching between the first pump and the second pump based on the first axis state and the second axis state of the multiple axis controller.

13. A method for delivering nonzero pressure to a surgical site within a patient, comprising:
-
controlling a first pump using a first signal received from a dual axis device indicating a first axis position to apply a first pressure to the surgical site of the patient; controlling a second pump using a second signal received from the dual axis device indicating a second axis position; and switching from the first pump to the second pump based on the second axis position; wherein said switching causes a gradual transition of pressure from the first pressure from the first pump to a second pressure from the second pump while pressure at the surgical site remains relatively constant. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. An apparatus for controlling vacuum pressure applied to a surgical site within a patient, comprising:
-
a multiple axis controller; a processing apparatus configured to receive multiple axis data from the multiple axis controller; a first pump configured to provide nonzero fluid pressure to the surgical site within the patient at a first nonzero fluid pressure level based on a first axis state of the multiple axis controller; and a second pump configured to provide nonzero fluid pressure at a second nonzero fluid pressure level based on a second axis state of the multiple axis controller; wherein the processing apparatus causes switching between the first pump and the second pump based on the first axis state and the second axis state of the multiple axis controller, wherein said switching causes a gradual transition of pressure from the first nonzero fluid pressure level from the first pump to the second nonzero pressure level pressure from the second pump while pressure at the surgical site remains relatively constant. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
