Modified device for transporting a container of biological products in a laboratory automation system
Described is a carrier device for a single container of biological products or single test tube, comprising a base with a cavity, and a closing element. The base has a central pin with a cavity in which an RFID transponder is accommodated, is rotationally coupled to a toothed rotor, and further comprises four coupling holes, obtained in four cylinders projecting upward and having vertical axes, in which pins of four vertical gripping fingers are inserted.
1. A carrier device for a single container of biological products or single test tube, comprising:
a base;
a toothed rotor;
four vertical gripping fingers;
a closing element; and
a spiral spring;
wherein the base comprises a first cavity, a central pin with a second cavity in which an RFID transponder is accommodated, four coupling holes obtained in four cylinders projecting upward and having vertical axes,
wherein the base is rotationally coupled to the toothed rotor,
wherein the toothed rotor comprises a hollow cylinder and a ring gear which is the toothed portion of the toothed rotor, the hollow cylinder being at a bottom of the ring gear and being able to rotationally engage the central pin of the base,
wherein each of said vertical gripping fingers comprises a gear which engages the ring gear of the toothed rotor, a first pin and a second pin,
wherein the second pins of the four vertical gripping fingers are inserted in the four coupling holes of the base,
wherein the closing element comprises coupling holes which engage the first pins of the vertical gripping fingers,
wherein the hollow cylinder has a diameter which is smaller than the diameter of the ring gear which therefore projects radially outward with respect to said hollow cylinder,
wherein the spiral spring comprises a first end and a second hook-shaped end,
wherein the spiral spring wounds around the hollow cylinder and is fixed to the toothed rotor by the first end which is inserted from a bottom of the ring gear into a hole of the ring gear, the second hook-shaped end of the spiral spring coupling to one of the cylinders of the base,
wherein the spiral spring has a radial size which is smaller than the diameter of the ring gear before and after the fixing of the spiral spring to the toothed rotor.
