1. A drug delivery device for animals, the device comprising:
- a. at least a first syringe coupled with a first tube connector and a second syringe coupled with a second tube connector;
b. a plurality of disposable tubes, including at least a first tube, a second tube, a third tube and a fourth tube;
c. at least one catheter adapted to be placed into an animal;
d. at least a first and second pinch valve, each pinch valve having a first position and a second position, the first position and the second position each configured to receive one of the plurality of disposable tubes therethrough and for control of fluid flowing through the plurality of disposable tubes without being in fluid communication with the fluid;
e. a first reservoir containing a first fluid, wherein the first tube passes through the first position of the first pinch valve and is configured to allow the first fluid to flow between the first reservoir and the first syringe through the first tube connector;
f. at least one second reservoir containing a drug fluid, wherein the second tube passes through the first position of the second pinch valve and is configured to allow the drug fluid to flow between the second reservoir and the second syringe through the second tube connector; and
g. a third tube connector in fluid communication with the at least one catheter, wherein the third tube passes through the second position of the second pinch valve and is configured to allow the drug fluid to flow between the second syringe and the catheter through the third tube connector, and wherein the fourth tube passes through the second position of the first pinch valve and is configured to allow the first fluid to flow from the first syringe to the catheter through the third tube connector.

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.

15. A drug delivery device for animals comprising a housing that holds:
-
a. at least a first, second and third tube connector; b. at least a first and second syringe inlet tube, each with a first end and a second end, wherein the second end of the first syringe inlet tube is connected to the first tube connector and the second end of the second syringe inlet tube is connected to the second tube connector; c. at least a first and second syringe, the first and second syringes being connected to the first and second tube connector, respectively; d. at least a first and second syringe outlet tube, each with a first end and a second end, wherein the first end of the first syringe outlet tube is connected to the first tube connector and the second end of the first syringe outlet tube is connected to the third tube connector and wherein the first end of the second syringe outlet tube is connected to the second tube connector and the second end of the second syringe outlet tube is connected to the third tube connector; e. at least a first and second reservoir wherein the first reservoir is connected to the first end of the first syringe inlet tube and the second reservoir is connected to the first end of the second syringe inlet tube; f. at least one catheter adapted to be placed into an animal; g. a system outlet tube with a first end and a second end, wherein the first end of the system outlet tube is connected to the catheter and the second end of the outlet tube is connected to the third tube connector; h. at least a first and second pinch valve, the first pinch valve having a first position through which the first syringe inlet tube passes and a second position through which the first syringe outlet tube passes and the second pinch valve having a first position through which the second syringe inlet tube passes and a second position through which the second syringe outlet tube passes, wherein in each of the first and second pinch valves only one of the first or second positions opens while the other position remains closed, without being in communication with the fluid, in order to control fluid passing through the syringe inlet tubes, the syringe outlet tubes, the system outlet tube and the catheter; and i. electronic circuitry that controls the opening and closing of the first and second positions of each of the first and second valves, such that the electronic circuitry operates to prime the at least one catheter, flush the system outlet tube and/or the at least one catheter and deliver fluid to the animal. - View Dependent Claims (16, 17, 18)
