This disclosure relates generally to RFID communications, and in some non-limiting embodiments or aspects, to a system, a device, a product, an apparatus, and/or a method for reading syringe information using RFID communications.
2D barcode readers may be used to decode 2D barcodes on syringes. 2D bar code readers may use a complex optical system that is manually triggered when a syringe is attached to the 2D bar code reader. This electro-mechanical triggering may not be reliable due to a relatively tight tolerance control associated with mating various components of an injection system for the syringe. In addition, the optical system for a 2D barcode reader may use an expensive barrel lens in a light transmission path, for which factory calibration is relatively difficult and yield rates are relatively low. Accordingly, there is a need for improved reading of syringe information.
Accordingly, provided are improved systems, devices, products, apparatus, and/or methods for reading syringe information.

Provided are improved systems, devices, products, apparatus, and/or methods for reading syringe information.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system typically includes an RFID reader and a plurality of RFID tags. The RFID reader communicates wirelessly with the RFID tags. The RFID tags may be passive tags, which have no power source and are powered by energy received wirelessly from the RFID reader, or active tags, which are powered by a local or internal power source (e.g., a battery, etc.). The RFID tags include an antenna and a device to electronically store information and/or data to be read from the RFID tags by the RFID reader (e.g., a memory chip, etc.).
RFID typically operates in three main frequency ranges: Low Frequency (LF) (e.g., about 120-150 KHz), High Frequency (HF) (e.g., about 13.56 MHz), and Ultra-High Frequency (UHF) (e.g., about 865-868 MHz in Europe and 902-928 MHz in the U.S.). The LF and HF frequency ranges use magnetically coupled systems where the fields of the RFID reader antenna and the fields of the RFID tag must line up for the RFID reader to read the RFID tag. The LF and HF frequency ranges work well if the orientation of the RFID tags with respect to the reader can be controlled. In contrast, in the UHF frequency range, the RFID tags may still be read if the field orientation of the RFID tags is not directly lined up with the RFID reader antenna. Accordingly, UHF RFID tags may perform better in situations in which the orientation of the RFID tags with respect to the RFID reader cannot be easily controlled and/or known.
An area in which UHF RFID tags can be read by an RFID reader may be controlled by changing a transmit power and/or receive signal gain of the system to make the area smaller or larger. However, UHF RFID has no mechanism for selecting a specific or single tag in a particular location. For example, a UHF RFID reader for reading syringe information from RFID tags on syringes may not be able to identify or differentiate a syringe intended to be scanned and/or being connected to an injection system from other syringes in a surrounding area.
Non-limiting embodiments or aspects of the present disclosure are directed to a system, a reader, and a method therefor including a first antenna, a second antenna spaced apart from the first antenna, an RFID reader circuit, and a processor. The first antenna and the second antenna are connected to the RFID reader circuit. The first antenna is configured to receive a first signal from an RFID tag. The second antenna is configured to receive a second signal from the RFID tag. The processor controls the RFID reader circuit to determine a first value of a signal parameter associated with the RFID tag based on the first signal and a second value of the signal parameter associated with the RFID tag based on the second signal, receives, from the RFID reader circuit, the first value and the second value, and determines, based on the first value and the second value, whether the RFID tag is located between the first antenna and the second antenna. In this way, a syringe including the RFID tag that is intended to be scanned and/or being connected to an injection system can be identified or differentiated from other syringes in a surrounding area that are not intended to be scanned and/or are not being connected to an injection system.

First antenna 202 and second antenna 204 may be connected to RFID reader circuit 208. First antenna 202 may be configured to receive a first signal from an RFID tag (e.g., first RFID tag 106, at least one second RFID tag 110, etc.). Second antenna 204 may be configured to receive a second signal (e.g., a second signal different than the first signal received by first antenna 202, etc.) from an RFID tag (e.g., first RFID tag 106, at least one second RFID tag 110, the same RFID tag from which first antenna 202 received the first signal, etc.).
Connector 206 may be configured to connect to a syringe (e.g., first syringe 104, at least one second syringe 108, etc.). Connector 206 may be located between first antenna 202 and second antenna 204. First antenna 202 and the second antenna 204 may be located a same distance from connector 206 (e.g., a same distance from a longitudinal axis of connector 206, etc.). For example, as shown in
RFID reader circuit 208 may be configured to determine a value of a signal parameter (e.g., a received signal strength indication (RSSI), etc.) associated with an RFID tag based on a signal (e.g., a UHF RFID signal, etc.) received from that RFID tag. For example, RFID reader circuit 208 (e.g., under control of processor 210, etc.) may determine a first value of a signal parameter associated with the RFID tag based on the first signal received by first antenna 202 and determine a second value of the signal parameter associated with the RFID tag based on the second signal received by second antenna 204. As an example, RFID reader circuit 208 (e.g., under control of processor 210, etc.) may determine an RSSI value of the first signal received by first antenna 202 and determine an RSSI value of the second signal received by second antenna 204.
Switch 207 may be configured to be actuated in response to a connection of a syringe (e.g., first syringe 104, etc.) to connector 206. For example, processor 210 may be in electrical communication with switch 207, and processor 210 may be programmed and/or configured to control RFID reader circuit 208 to determine the first value and the second value in response to an actuation of switch 207.
In some non-limiting embodiments or aspects, RFID reader circuit 208 includes a switching circuit (e.g., an RFID switch, a multiplexer, etc.). For example, RFID reader circuit 208 may include a ST25RU3993 module. As an example, first antenna 202 and second antenna 204 may be connected to the switching circuit, and the switching circuit may be configured to selectively couple first antenna 202 and second antenna 204 to RFID reader circuit 208. In such an example, processor 210 may control, using the switching circuit, RFID reader circuit 208 to selectively read a first signal from an RFID tag with first antenna 202 and a second signal from that same RFID tag with second antenna 204. The first signal from the RFID tag received with first antenna 202 and the second signal from that same RFID tag received with second antenna 204 may each include a unique identifier associated with the RFID tag, and RFID reader circuit 208 (and/or processor 210) may distinguish first and second signals from the same RFID tag (e.g., from first RFID tag 106, etc.) from first and/or second signals received with first antenna 202 and/or second antenna 204 from one or more other RFID tags (e.g., the at least one second RFID tag 110 on the at least one second syringe 108, etc.) based on the unique identifiers included in the received signals. However, non-limiting embodiments or aspects are not limited thereto, and RFID reader circuit 208 may include separate RFID reader modules (e.g., separate ST25RU3993 modules, etc.) for each of first antenna 202 and second antenna 204 to respectively read the first signal from the RFID tag with first antenna 202 and the second signal from that same RFID tag with second antenna 204.
Processor 210 may be connected to (e.g., in electrical communication with, etc.) RFID reader circuit 208. Processor 210 may receive, from RFID reader circuit 208, a first value of a signal parameter associated with an RFID tag and a second value of the signal parameter associated with that same RFID tag, and determine, based on the first value and the second value, whether the RFID tag is located between the first antenna and the second antenna (e.g., whether a syringe including the RFID tag is connected to connector 206, etc.). For example, processor 210 may determine whether the first value and the second value (e.g., the RSSI value of the first signal received by first antenna 202 and the RSSI value of the second signal received by second antenna 204, etc.) are substantially equal to each other (e.g., within a tolerance threshold, etc.). As an example, processor 210 may determine a difference between the first value and the second value and, in response to the determined difference satisfying a threshold difference, determine that the RFID tag associated with the same unique identifier included in those corresponding first and second signals is located between the first antenna and the second antenna (e.g., that a syringe including the RFID tag is connected to connector 206, etc.). In such an example, a syringe including the RFID tag that is connected to connector 206 may have substantially equal RSSI values for the first signal and the second signal. As an example, processor 210 may determine a difference between the first value and the second value and, in response to the difference failing to satisfy the threshold difference, determine that the RFID tag is not located between the first antenna and the second antenna (e.g., that the RFID tag is located outside the first antenna and the second antenna, that a syringe including the RFID tag is not connected to connector 206, etc.). In such an example, a syringe including the RFID tag that is not connected to connector 206 may have substantially different RSSI values (e.g., outside a tolerance threshold, etc.) for the first signal and the second signal.
Indicator 212 may be configured to provide an indication associated with information included in and/or associated with a signal received from an RFID tag (e.g., information included in a first signal received from an RFID tag with first antenna 202, information included in a second signal received that same RFID tag with second antenna 204, etc.). In some non-limiting embodiments or aspects, an indication may include at least one of the following: a unique identifier associated with the RFID tag, an indication that a syringe associated with the RFID tag is connected to connector 206, an indication that the syringe associated with the RFID tag is not connected to connector 206, information associated with a medication contained in the syringe associated with the RFID tag, or any combination thereof. In some non-limiting embodiments or aspects, reader device 102 may communicate the indication and/or the information associated therewith to remote computing system 114.
First shielding material 214 may surround a portion of first antenna 202. For example, first shielding material 214 may be configured such that first antenna 202 forms a directive beamforming antenna (e.g., in a 2-dimensional direction toward a top of

The at least one third antenna 218 may be configured to receive at least one third signal (e.g., at least one third signal different than the first signal received by first antenna 202 and the second signal received by second antenna 204, etc.) from an RFID tag (e.g., first RFID tag 106, at least one second RFID tag 110, the same RFID tag from which first antenna 202 received the first signal and from which second antenna 204 received the second signal, etc.). For example, RFID reader circuit 208 (e.g., under control of processor 210, etc.) may determine at least one third value of the signal parameter associated with the RFID tag based on the at least one third signal received by the at least one third antenna 218. As an example, RFID reader circuit 208 (e.g., under control of processor 210, etc.) may determine an RSSI value of the first signal received by first antenna 202, determine an RSSI value of the second signal received by second antenna 204, and determine an RSSI value of the at least one third signal received by the at least one third antenna 218.
Processor 210 may receive, from the RFID reader circuit 208, the at least one third value of the signal parameter associated with the RFID tag and determine, based on the first value, the second value, and the at least one third value, whether the RFID tag is located between the first antenna, the second antenna, and the at least one third antenna (e.g., whether a syringe including the RFID tag is connected to connector 206, etc.). For example, processor 210 may determine whether the first value, the second value, and the third value (e.g., the RSSI value of the first signal received by first antenna 202, the RSSI value of the second signal received by second antenna 204, and the RSSI value of the at least one third signal received by the at least one third antenna 218, etc.) are substantially equal to each other (e.g., within a tolerance threshold, etc.). As an example, processor 210 may determine one or more differences between the first value, the second value, and the third value and, in response to the determined difference(s) satisfying one or more threshold differences, determine that the RFID tag associated with the same unique identifier included in those corresponding first, second, and third signals is located between the first antenna, the second antenna, and the at least one third antenna (e.g., that a syringe including the RFID tag is connected to connector 206, etc.).

Device 300 may perform one or more processes described herein. Device 300 may perform these processes based on processor 304 executing software instructions stored by a computer-readable medium, such as memory 306 and/or storage component 308. A computer-readable medium (e.g., a non-transitory computer-readable medium) is defined herein as a non-transitory memory device. A non-transitory memory device includes memory space located inside of a single physical storage device or memory space spread across multiple physical storage devices.
Software instructions may be read into memory 306 and/or storage component 308 from another computer-readable medium or from another device via communication interface 314. When executed, software instructions stored in memory 306 and/or storage component 308 may cause processor 304 to perform one or more processes described herein. Additionally or alternatively, hardwired circuitry may be used in place of or in combination with software instructions to perform one or more processes described herein. Thus, embodiments or aspects described herein are not limited to any specific combination of hardware circuitry and software.
Memory 306 and/or storage component 308 may include data storage or one or more data structures (e.g., a database, etc.). Device 300 may be capable of receiving information from, storing information in, communicating information to, or searching information stored in the data storage or one or more data structures in memory 306 and/or storage component 308. For example, the information may input data, output data, medical data, or any combination thereof.
