Abstract

A system and method are disclosed for controlling an inventory of a plurality of point-of-care diagnostic devices. The plurality of devices includes at least one type of device. Each device is configured to perform at least one sample analysis. Each device has a usable lifetime. The inventory includes a main inventory and at least one subinventory. The inventory control system comprises a data input interface for entering data associated with the devices and a data output interface for displaying data associated with the devices. A memory stores data associated with the devices and stores steps of a computer program to automatically update the current number of devices in the at least one subinventory in response to an occurrence of an event that causes a change in the current number of devices in the at least one subinventory. The inventory control system comprises a processor for accessing the memory to execute the computer program.

12. The inventory control system of claim 8, wherein the code is a bar code, and the data input interface includes a bar code reader.

13. The inventory control system of claim 10, wherein the second code is a bar code, and the data input interface includes a bar code reader.

14. The inventory control system of claim 8, wherein the code is a radio-frequency identification code, and the data input interface includes a radio-frequency transceiver configured to read the radio-frequency identification code.

15. The inventory control system of claim 10, wherein the second code is a radio-frequency identification code, and the data input interface includes a radio-frequency transceiver configured to read the radio-frequency identification code.

16. The inventory control system of claim 1, wherein for each of the at least one subinventory, the data includes data associated with supplies of consumable items that are used in conjunction with the devices.

17. The inventory control system of claim 1, wherein the memory stores steps of a computer program to:

compile a profile;

determine whether additional devices are required for one of the at least one subinventory on the basis of the compiled profile; and
