Abstract

The current invention is related with the search, storage and collection of objects, more precisely of laboratory samples, more precisely blood tubes identified with barcodes. The current invention is useful for increasing the speed for finding a specific subject, without robotics or mechanical moving parts, thus allowing greater flexibility and simplicity of the system. The invention describes a storage with the combination of an array of sensors with an array of visual indicators, especially with light, coupled with a reader'"'"'s identification of objects. The array of sensors detects when a sample is deposited or removed, and the array of indicators is used to indicate the location of the sample wanted. Thus, the present invention has application in the areas of laboratory sample storage, logistics and general health care.

Claims

1. Storage method for objects in multiple units, each unit featuring multiple locations, wherein said units receive carriers placed upon them, for the placement of said objects, comprising the following steps for receiving an object:

a) identify the object being stored by common identification,

b) identify the carrier being used by common identification,

c) register the location and the carrier being used by a presence sensor, of a plurality comprised in the unit, one for each storage location, when the object is placed in one of those locations.

2. Storage method according to claim 1 further comprising the following steps for retrieving a previously stored object:

a) keep track of the location of that object in each unit and carrier,

b) indicate the location of that object for its collection through a visual indicator.

3. Storage method according to claim 1 further comprising the step of registering the change of location of an object to be collected and stored in different locations through the deferred and opposite activation of object sensors.

4. Storage method according to claim 1 wherein the common identification is performed by one or two-dimensional barcode, or identification by radio frequency, or optical character recognition, or by manually entering an ID code.

5. Storage device suitable for performing the process of claim 1 comprising:

a) multiple units, each unit featuring multiple locations to store objects;

b) carriers placed upon said units, for the placement of said objects;

c) an identifier in each carrier and a carrier identifier reader;

c) an identifier in each object and an object identifier reader;

d) one or more pairs of a presence sensor and a visual indicator, each pair corresponding to a storage location.

6. Storage device according to claim 5 wherein the visual indicators are light emitters and the carriers are transparent or translucent able to transmit.

7. Storage device according to claim 6 wherein the object sensor is an infrared photodiode or a mechanical switch.

8. Storage device according to claim 7 wherein the units comprising:

a communication device or wireless to a data processor for operation of the system, visual indicators through light-emitting diodes, object sensors using infrared photodiodes, and power supply.

9. Storage device according to claim 8 wherein the object sensors and the visual indicators are arranged in a matrix of rows and columns.

10. Storage device according to claim 9 wherein the object to store includes laboratory items, laboratory samples, test tubes, Petri dishes, microscope plates.

11. Storage device according to claim 10 wherein the object to be stored is documents, in particular, documents placed in envelopes.

12. Storage device according to claim 5 wherein the object sensor is an infrared photodiode or a mechanical switch.

13. Storage device according to claim 5 wherein the units comprising:

a communication device or wireless to a data processor for operation of the system, visual indicators through light-emitting diodes, object sensors using infrared photodiodes, and power supply.

14. Storage device according to claim 5 wherein the object sensors and the visual indicators are arranged in a matrix of rows and columns.

15. Storage device according to claim 5 wherein the object to store includes laboratory items, laboratory samples, test tubes, Petri dishes, microscope plates.

16. Storage device according to claim 5 wherein the object to be stored is documents, in particular, documents placed in envelopes.

17. Storage method according to claim 2 further comprising the step of registering the change of location of an object to be collected and stored in different locations through the deferred and opposite activation of object sensors.

18. Storage method according to claim 2 wherein the common identification is performed by one or two-dimensional barcode, or identification by radio frequency, or optical character recognition, or by manually entering an ID code.

19. Storage device suitable for performing the process of claim 2 comprising:

a) multiple units, each unit featuring multiple locations to store objects;

b) carriers placed upon said units, for the placement of said objects;

c) an identifier in each carrier and a carrier identifier reader;

c) an identifier in each object and an object identifier reader;

d) one or more pairs of a presence sensor and a visual indicator, each pair corresponding to a storage location.
