Description: THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS:
1. A fluid transference device comprising a hollow needle, a slot in the wall of the needle extending longitudinally the full length thereof, a flexible and circumferentially deformable catheter freely movable longitudinally within the needle and elbowed to project laterally from the needle through the slot, the slot being of a width inhibiting lateral separation of the needle from the catheter, whereby the needle may be moved longitudinally with respect to the catheter and separated therefrom.
2. A device as defined in claim 1, wherein the needle is affixed at its base to a handle.
3. A device as defined in claim 2, wherein the handle is angled with respect to the axis of the needle.
4. A device as defined in claim 2 or claim 3, wherein the end of the catheter projecting laterally from the needle is connected to an adaptor, the handle being channel-shaped to accommodate said adaptor.
5, A device as defined in claim 2 or claim 3, wherein the free end of the handle carries a hook.
6. A device as defined in claim 1, 2 or 3, wherein the catheter is polyethylene.
7. A device as defined in claim 1, 2 or 3, wherein the needle carries a bevelled point, the slot terminating at one end at the base of the bevel.
8. A device as defined in claim 1, including an adaptor into which the free end of the catheter projecting laterally from the needle is inserted, the end of the adaptor receiving the catheter defining an annular shoulder adapted to ride on the edges of the needle defining the slot.
9. A device as defined in claim 1, including an adaptor into which the free end of the catheter projecting laterally from the needle is inserted, and an annular guard adapted at one end to seat on the end of the adaptor and tapered at the other end to provide an annular shoulder ringing the catheter.
