Abstract

System and method of managing one or more surgical articles, wherein the surgical article can include a surgical sponge comprising an identification element, and wherein managing can include counting, locating, or both. The identification element can be a RFID tag. The RFID tag stores unique identification information relative to the surgical sponge. The system and method for detecting RFID tags may include a hand-held RFID reader operable in a first count-in mode and in a second count-out mode; the hand-held RFID reader may be receivable in a cradle that can determine the presence of the hand-held RFID reader in the cradle; and where operation of the hand-held RFID reader in the second count-out mode is enabled when the hand-held RFID reader is present in the cradle and the second count-out mode is disabled when the hand-held RFID reader is absent from the cradle.

Claims (39)

1. A surgical article system for managing removal of surgical articles following a surgical procedure, the surgical articles each including an identification tag comprising identification information identifying the corresponding surgical article, the system comprising:

a hand-held reader operable to read the identification information from the identification tags;

a cradle, the cradle adapted to receive the hand-held reader;

at least one processor; and

a non-transitory computer readable memory storing a set of instructions that when executed by the at least one processor causes the system to:

selectively operate the hand-held reader in a first count-in mode wherein the system stores information, based on the identification information, identifying the surgical articles as counted-in for use in the surgical procedure; and

selectively operate the hand-held reader in a second count-out mode wherein the system stores information, based on the identification information, identifying the surgical articles as counted-out and removed from the surgical procedure,

wherein the cradle is operable to determine a presence of the hand-held reader received in the cradle,

wherein the system enables an operation of the hand-held reader in the second count-out mode based on the presence of the hand-held reader received in the cradle,

wherein the system further comprises a user interface for receiving a user selection to operate the hand-held reader in the second count-out mode, and

wherein the set of instructions when executed by the at least one processor further causes the system to:

responsive to the user interface receiving the user selection to operate the hand-held reader in the second count-out mode when the hand-held reader is not present in the cradle, trigger an alert without triggering the hand-held reader to operate in the second count-out mode; and

responsive to the user interface receiving a user selection of an override option after the alert is triggered, trigger an operation of the hand-held reader in the second count-out mode.

2. The system of claim 1 , wherein the surgical articles are surgical sponges.

3. The system of claim 1 , wherein the hand-held reader comprises an RFID reader and wherein each identification tag comprises an RFID tag.

4. The system of claim 1 , wherein the hand-held reader comprises the at least one processor and the non-transitory computer readable memory storing the set of instructions.

5. The system of claim 4 , wherein the hand-held reader further comprises a display device and an input device, and wherein the set of instructions when executed by the at least one processor further causes the system to display on the display device a status of the hand-held reader selectively operated in the first count-in mode or the second count-out mode.

6. The system of claim 5 , wherein the set of instructions when executed by the at least one processor further causes the system to display information selected from among the identification information of the surgical articles, a count of surgical articles identified as counted-in, a count of surgical articles identified as counted-out, and combinations thereof.

7. The system of claim 1 , further comprising a base unit in electronic communication with the hand-held reader, the base unit comprising the at least one processor, the non-transitory memory storing the set of instructions, a display device, and an input device; and wherein the set of instructions when executed by the at least one processor further causes the system to display on the display device a status of the hand-held reader selectively operated in the first count-in mode or the second count-out mode.

8. The system of claim 7 , wherein the set of instructions when executed by the at least one processor further causes the system to display information selected from among the identification information of the surgical articles, a count of surgical articles identified as counted-in, a count of surgical articles identified as counted-out, and combinations thereof.

9. The system of claim 7 , wherein the base unit is a tablet computing device and the input device is a touchscreen of the tablet computing device.

10. The system of claim 9 , further comprising a mobile pedestal stand having a pole, the base unit and the cradle supported on the pole; and the pedestal stand arranged to be disposed outside a sterile field of the surgical procedure.

11. The system of claim 1 , wherein the cradle comprises a switch, wherein the hand-held reader, when received by the cradle, actuates the switch, and wherein the cradle is operable to determine the presence of the hand-held reader received in the cradle based on the actuation of the switch.

12. The system of claim 1 , wherein the cradle is operable to determine a presence of the hand-held reader received in the cradle via near field communication between the cradle and hand-held reader.

13. The system of claim 12 , wherein the near field communication between the cradle and the hand-held reader requires a proximity between the cradle and hand-held reader present only when the reader is received in the cradle.

14. The system of claim 12 , further comprising a base unit, the base unit comprising the at least one processor, the non-transitory memory storing the set of instructions, a display device, and an input device; and wherein the base unit is in electronic communication with the hand-held reader via a Bluetooth communication protocol.

15. The system of claim 14 , wherein a Bluetooth pairing is made between the base unit and the hand-held reader based on information communicated via the near field communication between the hand-held reader and the cradle.

16. The system of claim 1 , wherein the cradle is operable to determine a presence of the hand-held reader repeatedly while the system is selectively operating the hand-held reader in the second count-out mode.

17. The system of claim 16 , wherein the set of instructions when executed by the at least one processor further causes the system to trigger an alert and terminate operating the hand-held reader in the second count-out mode based on the cradle determining the hand-held reader is not present in the cradle.

18. A method executed by at least one processor for managing removal of surgical articles following a surgical procedure, the surgical articles each including an identification tag comprising identification information identifying the corresponding surgical article, the method comprising:

operating a hand-held reader in a first count-in mode including storing information identifying the surgical articles as counted-in for use in the surgical procedure;

operating the hand-held reader in a second count-out mode including storing information identifying the surgical articles as counted-out and removed from the surgical procedure;

determining a presence or absence of the hand-held reader in a cradle, wherein operating the hand-held reader in the second count-out mode is based on the determination of the hand-held reader being present in the cradle;

receiving via a user interface a user selection to operate the hand-held reader in the second count-out mode when the hand-held reader is not present in the cradle;

responsive to receiving the user selection to operate the hand-held reader in the second count-out mode when the hand-held reader is not present in the cradle, triggering an alert without triggering the hand-held reader to operate in the second count-out mode;

receiving via the user interface a user selection of an override option after the alert is triggered; and

responsive to receiving the user selection of the override option after the alert is triggered, triggering operation of the hand-held reader in the second count-out mode.

19. The method of claim 18 , further comprising: determining the hand-held reader has been removed from the cradle; and terminating operation of the hand-held reader in the second count-out mode based on the determination that the hand-held reader has been removed from the cradle.

20. The method of claim 18 , wherein the surgical articles are surgical sponges.
