Claim Text:
1. A device for inserting or removing fluids in an oviduct of a sow, comprising: a rigid tubular body; a flexible tube having opposing flexible tube proximal and distal ends, the flexible tube located coaxially through the rigid tubular body, wherein the flexible tube proximal end connects to a beveled needle, wherein coaxial movement of the flexible tube within the rigid tubular body allows the beveled needle to be inserted in the oviduct when the rigid tubular body is located in the vicinity of the oviduct; one or more sheaths directly connected or connected through a double cock to the flexible tube distal end; and one or more pistons closing the one or more sheaths, wherein the one or more pistons slide one each through the inside of the one or more sheaths; wherein the rigid tubular body has a configuration which locks the one or more sheaths at a location in the rigid tubular body with the beveled needle extended outside of the rigid tubular body, and wherein evacuation of the device is done by unlocking the one or more sheaths pulling the beveled needle back into the rigid tubular body.
