Abstract

An automated syringe handling system that will safely, securely, and quickly assemble syringes or other medical devices under controlled/sterile conditions while maintaining the syringes in a stable orientation and eliminating unnecessary operator contact with the syringes and working area.

Claims (33)

1. An automatic syringe filling station comprising:

at least one syringe magazine comprising at least one inclined slope, wherein the inclined slope is configured to incline at substantially 10 degrees;

at least one syringe cam, in communication with the at least one syringe magazine, comprising a cam finger and a cam blocking guard wherein the at least one syringe cam is configured to remove at least one syringe from the at least one syringe magazine;

at least one gripper assembly for removing the at least one syringe from the at least one syringe cam after the at least one syringe cam moves the at least one syringe from the at least one syringe magazine to a selection location wherein the at least one gripper assembly engages the at least one syringe, wherein the gripper assembly comprises at least two gripper fingers configured to engage the at least one syringe and provide axial, translational and rotational constraint of the at least one syringe;

the at least one gripper finger is attached to at least one gripper body to form at least one conjoined gripper;

a coupler connecting the at least one conjoined gripper to at least one articulated armature configured to manipulate and move the at least one syringe;

at least one filling block for injecting liquid into the at least one syringe;

at least one cap array including at least one gravity fed capping dispenser with at least a first gate and a second gate configured to provide at least one cap for engagement with the at least one articulated armature and to place the at least one cap on the at least one syringe; and

all of the above contained in an enclosure configured to have at least one removable panel configured to allow access to an interior of the enclosure.

2. The automatic syringe filling station of claim 1 , wherein the at least one syringe cam is pneumatically powered.

3. The automatic syringe filling station of claim 1 , wherein the at least one syringe is oriented within the at least one syringe magazine and at least one syringe cam with a Luer lock of the at least one syringe oriented downward.

4. The automatic syringe filling station of claim 1 , wherein the at least one syringe cam is biased to return to engage at least one other syringe contained in the at least one syringe magazine.

5. The automatic syringe filling station of claim 1 , wherein the cam blocking guard prevents release of at least one other syringe as the at least one syringe is moved.

6. The automatic syringe filling station of claim 1 , wherein the at least one gripper assembly can be disassembled to replace portions of the at least one gripper assembly.

7. The automatic syringe filling station of claim 1 , wherein the cap array defines voids that engage at least one syringe cap.

8. The automatic syringe filling station of claim 1 , wherein the filling block has at least one face of the filling block aerodynamically shaped to improve air flow.

9. A method for automatically filling a syringe comprising:

loading at least one syringe into at least one syringe magazine comprising at least one inclined slope, wherein the inclined slope is configured to incline at substantially 10 degrees;

having a cam finger supported on a syringe cam, in communication with the at least one syringe magazine, receiving at least one syringe from the at least one syringe magazine, wherein the syringe cam is configured to remove at least one syringe from the at least one syringe magazine;

moving the syringe cam such that the at least one syringe moves from a syringe rail exit while a syringe cam blocking guard prevents egress of at least one other syringe contained within the at least one syringe magazine;

engaging the at least one syringe with at least one gripper assembly after the syringe cam moves the at least one syringe from the at least one syringe magazine to a selection location wherein the at least one gripper assembly engages the at least one syringe, wherein the gripper assembly comprises at least two gripper fingers configured to engage the at least one syringe and provide axial, translational and rotational constraint of the at least one syringe;

the at least one gripper finger is attached to at least one gripper body to form at least one conjoined gripper;

a coupler connecting the at least one conjoined gripper to at least one articulated armature configured to manipulate and move the at least one syringe;

placing the at least one syringe in a filling block and holding the at least one syringe in place;

filling the at least one syringe with liquid;

moving the at least one syringe to engage at least one cap array including at least one gravity fed capping dispenser with at least a first gate and a second gate configured to provide at least one cap for engagement with the at least one articulated armature and to place the at least one cap on the at least one syringe; and

placing a cap on the at least one syringe.

10. The method of claim 9 , wherein the at least one syringe is oriented within the at least one syringe magazine and syringe cam with a Luer lock of the at least syringe oriented downward.

11. The method of claim 9 , comprising biasing the at least one syringe cam to return to engage the at least one other syringe contained in the at least one syringe magazine.

12. The method of claim 9 , further comprising disassembling the at least one gripper assembly to replace portions of the at least one gripper assembly.

13. The method of claim 9 , further comprising securing syringe caps via a cap array.

14. The method of claim 9 , further comprising aerodynamically shaping the filling block to promote air flow around the filling block.

15. The method of claim 9 , further comprising pneumatically powering the at least one syringe cam.
