Point-of-care inventory management system and method
First Claim
1. A point of care testing device comprising:
- an analysis component configured to perform at least one sample analysis; and
a time indicator configured to;
provide a first code or signal associated with the device that indicates a first time when the device is transferred from a controlled main inventory to an ambient temperature subinventory; and
provide a second code or signal associated with the device that indicates a second time prior to the device performing said at least one sample analysis,wherein a comparison between a predetermined ambient shelf life of the device and a time difference between said first time and said second time provides an indication of whether the device has expired; and
said predetermined shelf life provides a usable lifetime of the device at ambient temperature.

Abstract
A system and method are disclosed for controlling an inventory of point-of-care diagnostic devices. The inventory includes a main inventory and at least one subinventory. Each device has an ambient temperature shelf life. Data associated with the devices is entered, including: the current quantity and predetermined minimum quantity of devices in the main inventory; and the current quantity and predetermined minimum quantity of devices in the subinventory. A first timestamp is associated with each device when the device is transferred from the main inventory to the ambient temperature subinventory. The first timestamp is compared to a second timestamp prior to use of the device to determine whether the device'"'"'s ambient temperature shelf life is exceeded. The current quantity of devices in the subinventory is updated in response to an event that causes a change in the current quantity of devices in the subinventory.

2. A point of care testing system comprising:
-
a disposable device comprising; a port configured to receive a patient sample; and a time indicator configured to; provide a first code or signal associated with the disposable device that indicates a first time at which the disposable device has been moved from a refrigerated storage condition to an ambient storage condition; and provide a second code or signal associated with the disposal device that indicates a second time prior to the disposable device receiving said patient sample; and a reusable reader comprising; a port configured to receive said disposable device; and an identification device configured to; receive said first code or signal and said second code or signal; determine a time difference between said first time and said second time; compare said time difference to a predetermined ambient shelf life of the disposable device; and when said time difference is greater than said predetermined ambient shelf life, provide an indication that a usable lifetime of the disposable device has expired. - View Dependent Claims (3, 4)

5. A point of care testing system comprising:
-
a disposable device comprising; a port configured to receive a patient sample; and a time indicator configured to provide a first code or signal associated with the disposable device that indicates a first time at which the disposable device has been moved from a refrigerated temperature to an ambient temperature; and a reusable reader comprising; a port configured to receive said disposable device; and an identification device configured to; receive said first code or signal; determine a second time when the disposable device will expire due to exposure to said ambient temperature based on a predetermined ambient temperature expiration date assigned to the disposable device; determine whether said second time has elapsed prior to use of the disposable device to determine whether an ambient temperature shelf life of the disposable device at the ambient temperature is exceeded; and when said second time has elapsed, lock out the disposable device such that the disposable device is prevented from being used.
