Abstract

An apparatus and system including an apparatus to identify an identifier on a tissue cassette in an assembly of a plurality of tissue cassettes including a light source operable to illuminate a plurality of tissue cassettes; a sensor operable to automatically capture an identifier on an individual tissue cassette or an image of the plurality of tissue cassettes in the assembly; and where the sensor is operable to capture reflected light from the light source of an image of the plurality of tissue cassettes, a converter to convert image data into an electronic signal. The system may include a processor operable to compare an identifier with a tissue processing protocol. A method including sensing identifiers on tissue cassettes each containing a tissue sample in an assembly comprising a plurality of tissue cassettes; and determining or verifying a tissue processing protocol of a tissue sample based on the sensed identifier.

First claim

What is claimed is:

1 . An apparatus to identify an identifier on a tissue cassette in an assembly of a plurality of tissue cassettes comprising:
a light source operable to illuminate a plurality of tissue cassettes in an assembly of a plurality of tissue cassettes, the assembly comprising sidewalls and a base that define a volume and an exposed top surface, the assembly capable of containing a plurality of tissue cassettes together in an upright position so that a front sidewall of each of the plurality of tissue cassettes faces outward from the top surface of the assembly; a base defining an assembly area operable to contain the assembly of a plurality of tissue cassettes; a sensor positioned above the base and over the assembly area, the sensor operable to automatically capture an identifier on a front sidewall of an individual tissue cassette by scanning and/or imaging the identifier or an image of the plurality of tissue cassettes in the assembly,
wherein the sensor is moveable to allow a capture and read of an identifier by the sensor on a tissue cassette positioned at a first location in the assembly area by the sensor in a first location or a capture and read of an identifier on a tissue cassette positioned at a different second location in the assembly area by the sensor in a second location, and
wherein the sensor is operable to capture reflected light from the light source of an image of the plurality of tissue cassettes, a converter to convert image data into an electronic signal; and
a processor comprising non-transitory program instructions to:
direct a rotational movement of the sensor about an axis;
direct the sensor to scan a defined portion of the assembly area selected by a user and capture and read an identifier on a tissue cassette positioned anywhere in the defined portion of the assembly area and, where there are a plurality of tissue cassettes in the defined portion of the assembly area, to capture and read an identifier on each of the plurality of tissue cassettes while each of the plurality of tissue cassettes are contained together in the assembly; and
provide an alert when an identifier is unable to be captured or read by the sensor.

2 . The apparatus of claim 1 , wherein the base comprises an orientation designation for a container operable to contain the assembly of the plurality of cassettes and the apparatus further comprises:
a lid coupled to the base, the lid comprising the light source and the sensor.

3 . The apparatus of claim 2 , wherein the sensor comprises a barcode reader.

4 . The apparatus of claim 3 , wherein the sensor comprises a first sensor and the apparatus further comprises a second sensor operable to capture a three dimensional image.

5 . The apparatus of claim 2 , wherein the base comprises at least one recess formed therein, the at least one recess comprising dimensions to contain a container in the base at the orientation designation, wherein the container is operable to contain the assembly of the plurality of tissue cassettes.

6 . The apparatus of claim 5 , wherein the at least one recess comprises at least two recesses.

7 . The apparatus of claim 6 , wherein one of the at least two recesses is operable to contain a first container having first dimensions and the other of the at least two recesses is operable to contain a second container having second dimensions different than the first dimensions.

8 . The apparatus of claim 1 , wherein the sensor is operable to sense an image of the plurality of tissue cassettes in the assembly.

9 . The apparatus of claim 1 , wherein a mode of operating the apparatus consists of at least one of the following modes of operation:
save the captured identifier in a database within the apparatus; send the captured identifier to an exterior system; request processing protocol information from an exterior system and analyze whether there is any inconsistency between the information associated with the captured identifier and the processing protocol; and identify a color of the individual tissue cassette and analyze whether there is any inconsistency between the information associated with the captured identifier and a processing protocol defined by a color of the individual tissue cassette.

10 . The apparatus of claim 1 , wherein the processor further comprises non-transitory program instructions operable to:
i) obtain electronic information of the identified identifier on each of a plurality of individual tissue cassettes; ii) compare the obtained information to information previously entered or retrieved information about a desired tissue processing protocol; and iii) report the comparison.

11 . The apparatus of claim 10 , wherein the obtained information comprises information from an identifier on a reference cassette in the assembly.

12 . The apparatus of claim 10 , wherein the retrieved information comprises information regarding a color of a tissue cassette.

13 . The apparatus of claim 1 , wherein the assembly area is defined by two dimensions and the sensor is moveable in the two dimensions.

14 . An apparatus to identify an identifier on a tissue cassette in an assembly of a plurality of tissue cassettes comprising:
a light source operable to illuminate a plurality of tissue cassettes in an assembly of a plurality of tissue cassettes, the assembly comprising sidewalls and a base that define a volume and an exposed top surface, the assembly capable of containing a plurality of tissue cassettes together in an upright position so that a front sidewall of each of the plurality of tissue cassettes faces outward from the top surface of the assembly; a base defining an assembly area operable to contain the assembly of a plurality of tissue cassettes; a sensor positioned above the base operable to automatically capture an identifier on a front sidewall of an individual tissue cassette by scanning and/or imaging the identifier or an image of the plurality of tissue cassettes in the assembly,
wherein the sensor is rotatable about an axis to allow a capture and read of an identifier on a tissue cassette positioned at a first location in the assembly area by the sensor in a first location or a capture and read of an identifier on a tissue cassette positioned at a different second location in the assembly area by the sensor in a second location, and
wherein the sensor is operable to capture reflected light from the light source of an image of the plurality of tissue cassettes, a converter to convert image data into an electronic signal; and
a processor comprising non-transitory program instructions to:
direct a rotational movement of the sensor about an axis; and
direct the sensor to capture and read an identifier on a tissue cassette positioned anywhere in the assembly area and, where there are a plurality of tissue cassettes in the assembly area, to capture and read an identifier on each of the plurality of tissue cassettes while each of the plurality of tissue cassettes are contained together in the assembly.
