Abstract

The disclosure pertains to an automated apparatus for filling capped needle syringes. The syringes are held in a rotatable motor controlled carousel. The carousel turns to place a syringe proximate to a dispenser mechanism. A rotatable plate on top of the dispenser mechanism holds an automated cap extractor/installer and at least one inverted vial having a needle perforatable surface. The rotatable plate can also move up and down relative to the top of the dispenser mechanism. The cap can be removed by the automated cap extractor/installer and the rotatable plate rotated to place the inverted vial over the exposed syringe needle. The rotatable plate can descend so that the needle perforates the surface of the vial. A syringe plunger tool of the dispenser mechanism engages the syringe plunger and pulls it downward. The syringe plunger tool can disengage and return to its original position. The rotatable plate can raise to remove the needle from the vial. The rotatable plate can rotate to place the automated cap extractor/installer over the exposed needle. The automated cap extractor/installer holding the syringe needle cap can descend and the cap reattached to the syringe. The carousel can rotate to present the filled and capped syringe to an automated syringe inverter/extractor component that removes the capped syringe from the carousel and places the syringe in a holder.

Claims

1. An automated method for the filling of syringes comprising:

a) placing a syringe in an optional single syringe holder mount on a motor controlled filler mechanism;

b) a syringe plunger tool rotating from a first position of the motor controlled filler mechanism and engaging the syringe plunger at a second position;

c) an automated needle cap extractor mounted on a motor controlled rotatable plate descending from a third position to a fourth position and grasping a syringe cap and removing the syringe cap by returning to the third position;

d) the rotatable plate rotating horizontally to a fifth position wherein a perforatable surface of an inverted vial is positioned above an uncapped syringe needle;

e) the vial descending to a sixth position upon the needle;

f) the syringe plunger tool pulling the syringe plunger downward a controlled distance to a seventh position;

g) the vial moving upward from the sixth position and returning to the fifth position causing the syringe needle to be extracted from the vial;

h) the rotatable plate rotating the automated needle cap extractor horizontally to the third position with the cap component directly above the needle;

i) the automated needle cap extractor descending to the fourth position upon the needle and replacing the needle cap; and

j) the syringe plunger tool disengaging from the syringe plunger and returning to the fifth position and automated needle cap extractor returning to the third position.

2. An automated method for the filling of syringes comprising:

a) a motor controlled rotatable carousel in a horizontal plane holding vertically one or more syringes wherein a cap of the syringe is on top and a syringe plunger is on the bottom;

b) locating a motor controlled filler mechanism proximate to the rotatable carousel;

c) a syringe plunger tool rotating from a first position of the motor controlled filler mechanism and engaging the syringe plunger held in the carousel at a second position;

d) an automated needle cap extractor mounted on a motor controlled rotatable plate descending from a third position to a fourth position and grasping a syringe cap and removing the syringe cap by returning to the third position;

e) the rotatable plate rotating horizontally to a fifth position wherein a perforatable surface of an inverted vial is positioned above an uncapped syringe needle;

f) the vial descending to a sixth position upon the needle;

g) the syringe plunger tool pulling the syringe plunger downward a controlled distance to a seventh position;

h) the vial moving upward from the sixth position and returning to the fifth position causing the syringe needle to be extracted from the vial;

i) the rotatable plate rotating the automated needle cap extractor horizontally and stopping at the third position with the cap component directly above the needle;

j) the automated needle cap extractor descending to the fourth position upon the needle to replace the needle cap; and

k) the syringe plunger tool disengaging from the syringe plunger and returning to the fifth position and the automated needle cap extractor returning to the third position.

3. The method of claim 2 further comprising the steps:

a) the motor controlled carousel rotating to a seventh position proximate to a motor controlled syringe inverter wherein a gripping jaw subcomponent of the syringe inverter moves from a eighth position to a ninth position and grasps the syringe and retracts to the eighth position whereby the syringe is removed from the carousel;

b) the syringe inverter holding the syringe with the syringe cap at the top rotates in a vertical plane to a tenth position wherein the syringe cap is at the bottom and the gripping jaw sub-component is released.

4. The method of claim 2 further comprising reading a barcode on the syringe.

5. The method of claim 2 further comprising reading a barcode on a vial.

6. An automated apparatus for the filling of syringes comprising a single syringe adapter/holder, a syringe plunger tool that is rotatable and can be raised and lowered, and a rotatable plate that can be raised and lowered and capable of holding at least one inverted vial and an automated needle cap extractor.

7. The apparatus of claim 6 wherein the automated needle cap extractor comprises a rack and modified pinion.

8. An automated apparatus for the filling of syringes comprising:

a) a motor controlled removable rotatable carousel in a horizontal plane and capable of holding vertically one or more capped syringes wherein a capped syringe is on top and a syringe plunger is on the bottom; and

b) a motor controlled filler mechanism located proximate to the rotatable carousel and comprising a syringe plunger tool that is rotatable and can be raised and lowered, and a rotatable plate that can be raised and lowered and capable of holding at least one inverted vial and an automated needle cap extractor.

9. The apparatus of claim 8 wherein the automated cap extractor/installer comprises a rack and modified pinion.

10. The apparatus of claim 8 further comprising a motor controlled syringe inverter/extractor comprising a gripping jaw subcomponent that can be moved forward and back and rotated.

11. The apparatus of claim 8 further comprising a barcode reader.

12. The apparatus of claim 11 wherein the barcode reader is mounted on the filler mechanism.

13. The apparatus of claim 8 wherein the inverted vial contains radiopharmaceuticals.

14. The apparatus of claim 9 further comprising a rotatable plate capable of holding up to three inverted vials.

15. The apparatus of claim 9 wherein at least one motor control is a step motor.

16. The apparatus of claim 9 wherein at least one motor is a servo motor.

19. The apparatus of claim 9 further comprising a rotatable plate capable of holding up to five inverted vials.

20. The apparatus of claim 9 further comprising a rotatable plate capable of holding up to six inverted vials.

17. An automated cap extractor/installer comprising
