Abstract

Disc dispensing device for dispensing discs impregnated with antibiotics onto a culture dish. The device comprises a stationary support on which a magazine is removably mounted. The magazine holds a plurality of tubular containers each containing a stack of discs to be dispensed. A moving means moves one disc from a bottom end of a tubular container to a pick-up position. From the pick-up position a transfer means picks up said one disc and transfers it to the culture dish where it is dispensed. The removable culture dish is supported by a moveable carriage which is mounted on the stationary support. The carriage is moveable relative to the magazine from a starting position to an operating position and vice versa. Control means control the operation of the device. The plurality of tubular containers is rotatable around a magazine center under control of the control means.

First claim

The invention claimed is:

1. Disc dispensing device for dispensing discs impregnated with antibiotics onto a culture dish, said disc dispensing device comprising:
a stationary support;
a magazine removably mounted on the stationary support, said magazine being arranged for holding a plurality of tubular containers, each tubular container being adapted for containing a stack of discs to be dispensed,
a conveyor positioned to move one disc from a bottom end of a tubular container to a pick-up position,
a transfer tool configured to pick up said one disc from the pick-up position, and transfer said one disc to the culture dish and dispense said one disc onto the culture dish,
a moveable carriage for supporting a culture dish which is placed on and removeable therefrom, said moveable carriage being mounted on the stationary support and being moveable relative to the magazine from a starting position to an operating position and vice versa,
a controller for the operation of the conveyor and the operation of the transfer tool, said controller being activated to control the conveyor and the transfer tool to dispense a disc impregnated with antibiotics onto the culture dish in the operating position of the carriage,
wherein the plurality of containers is rotatable around a magazine center under control of the controller.

2. Disc dispensing device as claimed in claim 1 , wherein the operating position is spaced from the center of the magazine.

3. Disc dispensing device as claimed in claim 1 or 2 , wherein the conveyor moves one disc from a bottom end of a tubular container to a pick-up position in a radial direction outwardly from the center of the magazine.

4. Disc dispensing device as claimed in claim 3 , wherein the pick up position is fixed relative to the stationary support.

5. Disc dispensing device as claimed in claim 1 or 2 , wherein said carriage comprises a rotatable support for the culture dish.

6. Disc dispensing device as claimed in claim 1 or 2 , wherein the disc dispensing device further comprises culture dish reader for detecting and reading an identifying mark on a culture dish, said culture dish reader being connected to the controller for providing a signal indicative of the read identifying mark of the culture dish to the controller.

7. Disc dispensing device as claimed in claim 1 or 2 , wherein the disc dispensing device further comprises tubular container—reader for detecting and reading an identifying mark on a tubular container, said tubular container reader being connected to the controller for providing a signal indicative of the read identifying mark of the tubular container to the controller.

8. Disc dispensing device as claimed in claim 7 , wherein the controller is adapted for operating in a first operation mode for at least one of controlling the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on the signal indicative of the read identifying mark of the culture dish and the signal indicative of at least one of the read identifying mark of the tubular container, and based on software programs loaded on a processor of the controller.

9. Disc dispensing device as claimed in claim 7 , wherein the controller comprises a communication interface to an external device for sending and receiving information to and from said external device, respectively, said controller being adapted for operating in a second operation mode for controlling at least one of the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on at least one of the signal indicative of the read identifying mark of the culture dish and the signal indicative of the read identifying mark of the tubular container, and based on received external information.

10. Disc dispensing device as claimed in claim 7 , wherein the controller comprises a memory, said controller being adapted to activate the tubular container either automatically or responsive to manual input during rotation of the plurality of containers for reading all the tubular container identifying marks, and being adapted for automatically inputting the signals indicative of the read tubular container identifying marks into the memory, indicating the position and content of each of the plurality of tubular containers within the magazine, and wherein said controller is adapted for controlling at least one of the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer means based on the input position and content of each of the plurality of tubular containers contained in the memory and based on suitable software programs loaded on a processor of the controller.

11. Disc dispensing device as claimed in claim 10 , wherein the controller is adapted for operating in a first operation mode for at least one of controlling the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on the signal indicative of the read identifying mark of the culture dish and the signal indicative of at least one of the read identifying mark of the tubular container, and based on software programs loaded on a processor of the controller.

12. Disc dispensing device as claimed in claim 10 , wherein the controller comprises a communication interface to an external device for sending and receiving information to and from said external device, respectively, said controller being adapted for operating in a second operation mode for controlling at least one of the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on at least one of the signal indicative of the read identifying mark of the culture dish and the signal indicative of the read identifying mark of the tubular container, and based on received external information.

13. Disc dispensing device as claimed in claim 6 , wherein the reader for detecting and reading comprises a bar code scanner.

14. Disc dispensing device as claimed in claim 6 , wherein the controller is adapted for operating in a first operation mode for at least one of controlling the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on the signal indicative of the read identifying mark of the culture dish and the signal indicative of at least one of the read identifying mark of the tubular container, and based on software programs loaded on a processor of the controller.

15. Disc dispensing device as claimed in claim 6 , wherein the controller comprises a communication interface to an external device for sending and receiving information to and from said external device, respectively, said controller being adapted for operating in a second operation mode for controlling at least one of the rotation of the plurality of tubular containers, the rotation of the culture dish, the operation of the conveyor and the operation of the transfer tool based on at least one of the signal indicative of the read identifying mark of the culture dish and the signal indicative of the read identifying mark of the tubular container, and based on received external information.

16. Disc dispensing device as claimed in claim 6 , wherein the disc dispensing device comprises a manual control
