Vial puck system for automatic drug compounder
A vial puck configured for attachment to a vial containing a drug is provided. The vial puck includes various features for facilitating uniform control of vials of various sizes in an automatic compounder system. The vial puck features may include a vial recess for receiving a vial of a particular size and securing the vial within the vial recess. The features may also include a cylindrical central portion, perpendicular extensions that extend from a top of the cylindrical central portion, a gear extending from the cylindrical central portion, and a sealing member disposed in the cylindrical central portion. The vial puck may include a cylindrical protrusion configured to press against a septum of the vial to form a seal between the vial puck and the vial. The sealing member may be configured to receive a needle of the compounder system therethrough to allow access to the vial.
1. A method, comprising:
providing a vial puck on a vial containing a drug;
providing the vial puck in a vial puck recess in a vial tray of a compounder system;
rotating the vial tray to move the vial and vial puck to a first position;
grasping the vial puck with vial calipers of the compounder system;
rotating the vial tray to move the vial and vial puck to a second position;
engaging a gear of the vial puck with a gear of the compounder system;
rotating the vial using the engaged gears of the vial puck and the compounder system;
lifting the vial puck and vial out of the vial tray with a vial lift coupled to the vial calipers; and
lifting the vial puck and vial to compress a needle housing of the compounder system to expose a needle assembly and to extend the needle assembly through sealing members of the vial puck and the needle housing into the vial.
2. The method of claim 1 , further comprising:
providing a diluent into the vial via the needle assembly;
agitating the vial while grasping the vial puck with the vial calipers; and
extracting a reconstituted drug from the vial via the needle assembly.
3. The method of claim 2 , further comprising, lowering the vial puck and vial, with the vial lift and vial calipers, to withdraw the needle assembly from the vial and from the sealing members.
4. The method of claim 3 , wherein the lowering comprises wiping the needle assembly with the sealing members.
5. The method of claim 4 , further comprising:
replacing the vial and vial puck into the vial puck recess in the vial tray with the vial lift and vial calipers;
rotating the vial tray; and
grasping and lifting an additional vial puck and attached vial from the vial tray with the vial lift and vial calipers.
6. The method of claim 1 , wherein providing the vial puck on the vial containing the drug comprises inserting the vial into a vial recess in a lower extension of the vial puck and securing the vial within the vial recess using a plurality of flanges within the vial recess.
7. The method of claim 6 , wherein providing the vial puck on the vial containing the drug further comprises pressing at least one cylindrical protrusion in the vial recess onto a vial septum of the vial.
