Abstract: A method for delivering a fluid to an animal with a drug delivery device without causing contamination to the drug delivery device. The drug delivery device used by the method may comprise a fluid subsystem with a switching device, disposable syringes, fluid reservoirs, disposable tubing, and a catheter. In one embodiment, the method allows a user to deliver multiple drugs to an animal without contaminating the valves that control the flow of fluid.

Abstract: A drug delivery device that utilizes a fluid subsystem with a switching device to deliver multiple drugs to an animal without causing contamination. The fluid subsystem can further comprise disposable syringes, fluid reservoirs, disposable tubing and a catheter. In the embodiments that utilize multiple disposable syringes, the drug delivery device allows a user to deliver multiple drugs to an animal through a catheter without contaminating the switching devices that control the flow of fluid. The drug delivery device can further utilize a controller to control the switching devices and a controller and syringe pumps to control the operation of the syringes.

Abstract: An electrocardiography device and method that is able to obtain the electrocardiogram of a freely moving animal. The device and method utilizes at least two catheters to obtain the electrical signals from the heart of the animal being tested. The catheters are filled with an electrically-conductive, physiological solution and are used in combination with at least two test leads that are able to transfer the electrical signals from the animal to an ECG monitoring device. The device and method also allows for fluids to flow through the catheters to other devices such as a blood sampler controller and/or an infusion pump.
