Abstract: A syringe system having a syringe with a body and a hollow barrel chamber, and a plunger shaft slidable therein, and a needle body. The syringe system includes a valve housing having a valve guide chamber with an input port fluidly connectable to a fluid pressurizing means, a storage port in fluid communication with the barrel chamber, and a discharge port in fluid communication with the needle body. A valve body is contained in the valve housing with a valve plunger slidable in the valve guide chamber. The valve plunger is slidable to a first position, where the dispensing port and storage empty port is closed and the input port and storage fill port are opened, and a second position where the input port and storage fill port is closed and the storage empty port and discharge port are opened.

Abstract: A syringe system having a syringe with a body and a hollow barrel chamber, and a plunger shaft slidable in the barrel chamber, and a needle body adapted for holding a needle. The syringe system includes a valve housing having a valve guide chamber therein, where the valve guide chamber has an input port fluidly connectable to a fluid pressurizing means, a storage port in fluid communication with the barrel chamber, and a discharge port in fluid communication with the needle body. A valve body is contained in the valve housing. The valve body includes a valve plunger slidable in the valve guide chamber, and a biasing member coupled to the valve plunger at a first end of the biasing member.

Abstract: With the use of a selectable fluid path assembly, the recovery and cleaning of the liquid path line is possible. Selecting the primary use path permits a syringe assembly to be filled with fluid in a positive pressure supplied fluid system. When the secondary fluid path is selected, the fluid in the line can be reversed and with negative pressure pulled back through the line up to the pump motor and moved back into the bottle. With air following the liquid a bubble can be detected and stop the fluid reversal. With the use of a selectable fluid path assembly, the prevention of contamination of the remaining liquid in the bottle can be prevent through proper use of the fluid recovery system.

Abstract: The syringe includes a body portion having an interior barrel chamber. The chamber has a fill port and a discharge port. An injection needle will be fluidly connected to the discharge port in use. The syringe includes a handle, having one portion that is moveable. Slidable in the barrel chamber is a plunger shaft, having a plunger on its terminal end. The trigger is operationally connected to the plunger shaft, so that movement of the trigger (or activation of the trigger in an electronic trigger embodiment) results in a corresponding movement of the plunger shaft. Connecting to the syringe are the fluid line, and a communications cable. Communications cable will include a power lead, if needed, and communications lines for communication between the syringe and the various computers.

Abstract: The invention concerns a syringe for administering medication to an animal. The syringe includes a handle that may be manually actuated to dispense medication to the animal. The syringe also includes a valve that controls the flow of medication both into and out of the syringe. A sensor device on the syringe monitors when the medication has been administered in order to inform any attached pump that the syringe may be refilled. An LED informs the user when the syringe has been filled with medication and is ready for the administration of medication to the animal.
