1. A tether and infusion system for a laboratory animal comprising:
- a platform suitable for carrying the laboratory animal;
a tether assembly, including a flexible conduit containing a plurality of infusion channels, for tethering the animal on the platform;
a torque sensor for detecting a motion of the animal on the platform; and
a drive means that drives the flexible conduit in response to a detected motion of the animal, thereby reducing the torque on the animal.

Abstract
A method and system for infusing and monitoring a tethered laboratory animal includes a platform suitable for carrying the laboratory animal. A tether assembly includes a flexible conduit for connecting to the animal and a tether for tethering the animal. A torque sensor detects a motion of the animal and drives the tether assembly in response to the detected motion of the animal, and thereby reduces the torque on the animal. The platform is driven in a direction opposite to the tether assembly so that it appears to be stationary when the tether assembly is driven in response to a detected motion of the animal.

12. The tether and infusion system according to claim 1, further including a means for differentiating a signal from the torque sensor so as to shut down the drive means if no activity is sensed for a fixed interval of time.
-
13. The tether and infusion system according to claim 12, wherein the fixed interval of time is 15 seconds.
-
14. A method for tethering and infusing an animal on a movable platform, comprising the steps of:
-
connecting a flexible conduit comprising a plurality of infusion channels to the animal;
providing a torque or motion sensor to detect a motion of the animal; and
driving the flexible conduit, in response to the detected motion, to reduce the torque on the animal. - View Dependent Claims (15, 16, 17)
driving the movable platform in a direction opposite to a driven direction of the flexible conduit so that the platform appears stationary to the animal.
