Syringe with multi-pronged actuator

1. A syringe having a distal end, a proximal end and comprising:

a syringe body having an inner fluid chamber;

a plunger positioned within the inner fluid chamber; and

a valve assembly at the distal end of the syringe, the valve assembly comprising:

a male coupling member configured for connecting a medical implement with a female coupling member to the syringe;

an outer sheath surrounding and spaced from the male coupling member and establishing an outer wall of the valve assembly, the outer sheath having a shoulder extending between a first inner diameter and a second inner diameter of the outer sheath, the second inner diameter being smaller than the first inner diameter;

a valve member having a flow passage therethrough and positioned within the male coupling member, the valve member having:

a closed position wherein the valve member is seated against the male coupling member closing access to the flow passage from outside of the male coupling member; and

an open position wherein the valve member is unseated from the male coupling member to allow access to the flow passage from outside of the male coupling member;

a back plate attached to the valve member;

at least three prongs each comprising a hinge attaching the prong to the back plate, and positioned between the male coupling member and the outer sheath, the at least three prongs attached to the valve member through the back plate and configured to move the valve member between the closed position and the open position, each of the prongs having a protrusion configured to engage the first inner diameter and the shoulder of the outer sheath when the valve member is in the closed position, the protrusion configured to force the prong inward towards the male coupling member when the valve member is moved to the open position from the closed position as the protrusion moves along the outer sheath from the first inner diameter to the smaller second inner diameter, wherein the at least three prongs are configured to rotate at the hinge when the valve member is moved to the open position from the closed position.

2. The syringe of claim 1 , wherein each prong comprises a first abutment element and a second abutment element spaced from the first abutment element.

3. The syringe of claim 1 , wherein the valve member, the back plate and the at least three prongs are integrally formed.

4. The syringe of claim 1 , wherein the male coupling member is integrally formed with the syringe body.

5. The syringe of claim 1 , wherein the at least three prongs are equally spaced around the back plate.
