Abstract
Description
Technical Field
[0001] The subject matter of the present disclosure generally relates to devices, systems, and methods for detecting medical device components, and in some particular embodiments or aspects, to devices, systems, and methods for detecting the mating of medical device components.
Background Art
[0002] Cross - reference to Related Applications This application claims priority to U.S. Provisional Patent Application No. 63 / 021,496, filed May 7, 2020, entitled "Device, System, and Method for Detection of Medical Device Components and / or Mating Thereof", the entire disclosure of which is incorporated herein by reference in its entirety.
[0003] Certain techniques for identifying products can include machine - readable optical labels (e.g., barcodes, quick response (QR) codes, etc.). For example, optical labels can be relatively inexpensive to affix to products and / or their packages (e.g., by sticking a sticker to the product and / or package, printing directly on the product and / or package, etc.). However, readers for such optical labels can have drawbacks such as using a relatively complex optical system, requiring a line of sight (e.g., between the reader and the optical label) for operation, the need to be manually aligned and / or triggered, and being difficult to use in automation.
[0004] Other techniques for identifying products may include radio frequency identification (RFID) tags. For example, such RFID tags may include an application specific integrated circuit (ASIC) and an antenna. The antenna may enable the transmission and / or reception of data via wireless communication, which may not require a line of sight for operation. The ASIC may enable the storage of data on the RFID tag, the reading of data from the RFID tag, and / or the writing of data to the RFID tag. However, such RFID tags can be relatively expensive, which may be at least partially due to the cost and / or time to produce the ASIC. Additionally, the ability to operate without a line of sight may be desirable for automation, but the increased cost of RFID tags (e.g., compared to optical labels) may not be suitable for the manufacture, identification, tracking, etc. of inexpensive products and / or disposable products (such as inexpensive medical device components and / or disposable medical device components).
[0005] In addition, while certain techniques (e.g., optical labels, RFID tags, etc.) can be used to identify individual products, such techniques may not be able to detect the fitting of products (e.g., the fitting of medical device components).

[0069] It should be understood that this disclosure may contemplate various alternative variations and step sequences unless explicitly specified otherwise. It should also be understood that the specific devices and processes shown in the accompanying drawings and described in the following specification are merely illustrative and non-limiting embodiments or aspects. Accordingly, the specific dimensions and other physical characteristics associated with the embodiments or aspects disclosed herein should not be considered limiting.
[0070] For the purposes of the following description, terms such as "end", "upper", "lower", "right", "left", "vertical", "horizontal", "top", "bottom", "lateral", "longitudinal", and derivatives thereof are to be considered in relation to the orientation in the drawings of the subject matter being disclosed. However, it should be understood that the subject matter being disclosed can assume various alternative deformations and step sequences, unless otherwise explicitly specified. It should also be understood that the specific devices and processes shown in the accompanying drawings and described in the following specification are merely exemplary embodiments or aspects of the subject matter being disclosed. Accordingly, specific dimensions and other physical characteristics related to the embodiments or aspects disclosed herein should not be considered limiting, unless otherwise indicated.
[0071] As used herein, aspects, components, elements, structures, operations, steps, functions, instructions, etc. should not be construed as important or essential unless explicitly described as such. Also, the articles "a" and "an" as used herein are intended to include one or more items and can be used in the same sense as "one or more" and "at least one". Further, the term "set" as used herein is intended to include one or more items (e.g., related items, unrelated items, combinations of related and unrelated items, etc.) and can be used in the same sense as "one or more" or "at least one". The term "one" or similar words are used when only one item is intended. Also, terms such as "has", "have", "having", etc. as used herein are intended to be open-ended terms. Further, the phrase "based on" is intended to mean "at least partially based on" unless otherwise specified.
[0072] As used herein, the terms "communicate" and "communicating" may refer to receiving, accepting, transmitting, transferring, providing, etc. of information (e.g., data, signals, messages, instructions, commands, etc.). For one unit (e.g., a device, a system, a component of a device or a system, a combination thereof, etc.) to communicate with another unit means that one unit can receive information directly or indirectly from the other unit and / or transmit information to the other unit. This may refer to a direct or indirect connection (e.g., a direct communication connection, an indirect communication connection, etc.) that is essentially wired and / or wireless. Additionally, two units can communicate with each other even if the information transmitted can be modified, processed, relayed, and / or routed between the first unit and the second unit. For example, even if the first unit receives information passively and does not actively transmit information to the second unit, the first unit can communicate with the second unit. As another example, when at least one intermediate unit (e.g., a third unit located between the first unit and the second unit) processes the information received from the first unit and communicates the processed information to the second unit, the first unit can communicate with the second unit. In some non-limiting embodiments or aspects, a message may refer to a network packet (e.g., a data packet, etc.) containing data. It will be understood that many other configurations are possible.
[0073] As used herein, the term "server" may refer to one or more computing devices such as a processor, a memory device, and / or similar computer components that communicate with client devices and / or other computing devices via a network such as the Internet or a private network, and in some instances facilitate communication between other servers and / or client devices. It will be understood that various other configurations are possible. Additionally, references to a "server" or "processor" herein may refer to a previously recited server and / or processor, a different server and / or processor, and / or a combination of servers and / or processors that are recited as performing a previous step or function. For example, as used in this specification and the claims, a first server and / or a first processor recited as performing a first step or function may refer to the same or a different server and / or processor recited as performing a second step or function.
[0074] Some non-limiting embodiments or aspects are described herein with respect to thresholds. As used herein, meeting a threshold may refer to a value being greater than a threshold, more than a threshold, higher than a threshold, greater than or equal to a threshold, less than a threshold, fewer than a threshold, lower than a threshold, less than or equal to a threshold, equal to a threshold, and the like.
[0075] Non-limiting embodiments or aspects of the disclosed subject matter are directed to devices, systems, and methods for detecting medical device components, including but not limited to, detecting the fitting of medical device components. For example, non-limiting embodiments or aspects of the disclosed subject matter provide a first medical device component having at least one first resonant structure (having a first resonant frequency spectrum) and a second medical device component having at least one second resonant structure (having a second resonant frequency spectrum), wherein when the first and second medical device components are fitted, the first and second resonant structures combine to have a third resonant frequency spectrum (different from the first and second resonant frequency spectra). Such embodiments or aspects provide techniques and systems that enable the wireless detection (e.g., identification, etc.) of individual medical device components and / or their fitted combinations, which advantageously may not require a line of sight for operation. For example, since a line of sight may not be required, such medical devices can be handled (e.g., in any orientation with respect to a reader, etc.) and further detected by a clinician in any manner. Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable such wireless detection (e.g., identification, etc.) without complex circuitry (e.g., integrated circuits, application specific integrated circuits (ASICs), memories, processors, etc.) formed on and / or fixed to the medical device components, thereby reducing (e.g., decreasing, etc.) the time, amount of resources, number of different resources, cost, etc. associated with the production and / or use of the disclosed subject matter (e.g., as compared to radio frequency identification (RFID) tags, etc.) and improving reliability, etc. (e.g., since there is no complex circuitry that can be damaged, degraded, etc.). Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable such wireless detection (e.g., identification, etc.) without a power source formed on and / or fixed to the medical device components, thereby reducing the cost and / or complexity for production and / or use.Additionally or alternatively, such embodiments or aspects provide techniques and systems that are suitable for automation (e.g., by wireless operation, reduction (e.g., elimination, decrease, etc.) of line of sight and / or alignment requirements for operation, reduction of time and / or cost for production and / or use, etc.). Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable detection of the fitting (e.g., proper connection, alignment, etc.) of two or more medical device components. Thus, the present techniques and systems can be useful for compliance tracking, for example, by tracking (e.g., detecting, recording, etc.) the connection and / or disconnection of medical device components (e.g., syringes and vascular access devices). For example, the connection and / or disconnection can be compared to a rule (e.g., a guideline, a defined treatment protocol, etc.) to determine compliance therewith. Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable location identification and / or tracking of each medical device component within a facility (e.g., using a plurality of leaders located at different (e.g., known) locations within the facility, each leader being able to detect nearby (e.g., within the operating range of the leader) medical device components). Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable inventory management and / or logistics (e.g., since the number and / or location of each type of medical device component within the facility can be determined at a given time, the inventory of at least one type of medical device component can be replenished and / or redistributed as needed (e.g., based on meeting a threshold associated with that inventory)). Additionally or alternatively, such embodiments or aspects provide techniques and systems that enable anti-counterfeiting (e.g., a fake medical device component can lack a resonant structure and / or resonant frequency spectrum, and / or have an incorrect resonant structure and / or resonant frequency spectrum).
[0076] For illustrative purposes, in the following description, the subject matter of the present disclosure is described with respect to devices, systems, and methods for detecting medical device components, e.g., for detecting the fitting of medical device components. However, those skilled in the art will recognize that the disclosed subject matter is not limited to the exemplary embodiments or aspects. For example, the devices, systems, and methods described herein can be used in any setting suitable for using a product, such as in manufacturing, shipping, inventory management, retail, food manufacturing, etc., for identifying such products and / or detecting fitting (e.g., of products and / or components of products) in a variety of settings.
[0077] Referring now to FIGS. 1A and 1B, FIGS. 1A and 1B are diagrams of non-limiting embodiments or aspects of an environment 100 in which the devices, systems, and / or methods described herein can be implemented.

[0078] The medical device assembly 102 can include at least one of the first medical device component 102a, the second medical device component 102b, any combination thereof, etc.
[0079] The first medical device component 102a may include at least one device and / or its components configured for use in a medical purpose. For example, the first medical device component 102a may include at least one device (e.g., an instrument, apparatus, tool, machine, mechanism, implant, any combination thereof, etc.) and / or its components, which may be configured for use in the diagnosis of a disease or other condition and / or in the cure, alleviation, treatment, and / or prevention of a disease and / or other condition (e.g., in a human, other animal, etc.). In some non-limiting embodiments or aspects, the first medical device component 102a may include a syringe.
[0080] In some non-limiting embodiments or aspects, the first medical device component 102a may include a first antenna element 108a. Additionally or alternatively, the first antenna element 108a may have a resonance frequency spectrum. For example, the first antenna element 108a may include at least one first resonance structure 104a, and each first resonance structure 104a may have a resonance frequency spectrum (e.g., a first resonance frequency spectrum). Additionally or alternatively, the first antenna element 108a may include a first metal strip 106a. In some non-limiting embodiments or aspects, the first resonance structure 104a may include at least one spiral resonator (e.g., a first spiral resonator). Additionally or alternatively, the first resonance frequency spectrum may include a first natural frequency of the first spiral resonator. In some non-limiting embodiments or aspects, the first spiral resonator may include a first spiral-shaped metal conductor adjacent to the first metal strip 106a (e.g., of the first antenna element 108a of the first medical device component 102a) (e.g., formed from the first spiral-shaped metal conductor). Additionally or alternatively, the first spiral-shaped metal conductor may have a first inductance, a first capacitance, and / or a first resistance value. In some non-limiting embodiments or aspects, the first natural frequency may be based on the first inductance, the first capacitance, and / or the first resistance value. Additionally or alternatively, the first natural frequency, the first inductance, the first capacitance, and / or the first resistance value may be based on the geometric and / or material properties of the first spiral resonator (e.g., as further described below with respect to FIGS. 2A and 2B). In some non-limiting embodiments or aspects, the first resonance structure 104a may include at least one first metal ribbon (e.g., an amorphous metal ribbon). Additionally or alternatively, the first resonance frequency spectrum may include a first natural frequency (e.g., a resonance frequency, etc.) of the first metal ribbon (e.g., an amorphous metal ribbon).For example, the first natural frequency f (e.g., resonance frequency, etc.) of the first metal ribbon (e.g., amorphous metal ribbon) can be determined based on the mathematical formula f≒(1 / 2πl)√(Y / ρ), where l represents the length, Y represents the Young's modulus, and ρ represents the density.
[0081] In some non-limiting embodiments or aspects, when querying the first medical device component 102a using the query signal 112, the first antenna element 108a (e.g., its first resonant structure 104a) can attenuate at least one first frequency component to form a first attenuated electromagnetic signal (e.g., the first reflected signal 114a). For example, the query signal 112 can include a multi-frequency electromagnetic signal. When querying the first medical device component 102a using the multi-frequency electromagnetic signal, the first antenna element 108a (e.g., its first resonant structure 104a) can attenuate at least one first frequency component of the multi-frequency electromagnetic signal corresponding to the first resonance frequency spectrum (as further described below with respect to FIGS. 3A and 3B) to form a first attenuated electromagnetic signal. In some non-limiting embodiments or aspects, the query signal 112 can provide energy to the first antenna element 108a (e.g., its first resonant structure 104a). Additionally or alternatively, the first antenna element 108a (e.g., its first resonant structure 104a) can operate independently of a power source (e.g., without a power source, etc.). In some non-limiting embodiments or aspects, the first antenna element 108a can transmit (e.g., retransmit, backscatter, etc.) the first attenuated electromagnetic signal.
[0082] In some non-limiting embodiments or aspects, the first metal strip 106a (e.g., at least a portion thereof) can be disposed circumferentially around the first medical device component 102a. Additionally or alternatively, the first metal strip 106a (e.g., at least a portion thereof) can be disposed longitudinally (e.g., axially, parallel to the axis of the first medical device component 102a, etc.) along the first medical device component 102a. In some non-limiting embodiments or aspects, at least a portion of the first metal strip 106a can be disposed at an end (e.g., distal end, etc.) of the medical device (e.g., such that when the first medical device component 102a is fitted to the second medical device component 102b, the first metal strip 106a can be in electrical contact and / or electromagnetic coupling with the second metal strip 106b).
[0083] In some non-limiting embodiments or aspects, the at least one first resonant structure 104a can include a plurality of first resonant structures 104a. In some non-limiting embodiments or aspects, the plurality of first resonant structures 104a (and / or a subset thereof) can be disposed circumferentially around the first medical device component 102a.

For example, each first resonant structure 104a (and / or each of a subset thereof) can be disposed on a separate scale marking on the first medical device component 102a (as will be further described below with respect to FIG. 6A, for example). In some non-limiting embodiments or aspects, each of the plurality of first resonant structures can include (e.g., be formed from, etc.) conductive ink.

For example, each of the first receiving antenna element and the first transmitting antenna element can include a disk-shaped metal conductor. Additionally or alternatively, the first receiving antenna element and the first transmitting antenna element can be attached to opposite ends of the first metal strip 106a. In some non-limiting embodiments or aspects, the first receiving antenna element and the first transmitting antenna element can be cross-polarized (e.g., to reduce interference between, for example, a received signal (e.g., an interrogation signal 112) and a reflected signal (e.g., a first reflected signal 114a)). For example, the first receiving antenna element can be arranged to be orthogonal to the first transmitting antenna element (e.g., the first receiving antenna element (e.g., its surface) can be arranged in a first plane (e.g., substantially in the plane, mainly in the plane, etc.), and the first transmitting antenna element (e.g., its surface) can be arranged in a second plane orthogonal to the first plane (e.g., substantially in the plane, mainly in the plane, etc.)).

In some non-limiting embodiments or aspects, the first fitting element 110a may include a Luer fitting (e.g., a male Luer fitting, a female Luer fitting, etc.). For example, the first fitting element 110a may include a male Luer fitting, and the second fitting element 110b may include a corresponding female Luer fitting. In some non-limiting embodiments or aspects, the first antenna element 108a (e.g., its first resonator 104a and / or its first metal strip 106a) may be disposed together with the first fitting element 110a (e.g., a male Luer fitting, etc.).

Additionally or alternatively, at least a part of the first antenna element 108a (e.g., at least a part of the first resonator 104a and / or the first metal strip 106a) may be disposed sufficiently close to the first fitting element 110a such that when the first medical device component 102a (e.g., its first fitting element 110a) is fitted to the second medical device component 102b (e.g., its second fitting element 110b), the first antenna element 108a (e.g., the first resonator 104a and / or the first metal strip 106a) can be in electrical contact and / or electromagnetic coupling with the second antenna element 108b (e.g., the second resonator 104b and / or the second metal strip 106b).

Additionally or alternatively, at least a part of the second antenna element 108b (e.g., at least a part of the second resonator 104b and / or second metal strip 106b) may be disposed sufficiently close to the second fitting element 110b such that when the second medical device component 102b (e.g., its second fitting element 110b) is fitted to the first medical device component 102a (e.g., its first fitting element 110a), the second antenna element 108b (e.g., the second resonator 104b and / or second metal strip 106b) can be in electrical contact and / or electromagnetic coupling with the first antenna element 108a (e.g., the first resonator 104a and / or first metal strip 106a).
[0099] In some non-limiting embodiments or aspects, when the first medical device component 102a (e.g., its first mating element 110a) is mated with the second medical device component 102b (e.g., its second mating element 110b), the first antenna element 108a (e.g., its first resonant structure 104a) and the second antenna element 108b (e.g., its second resonant structure 104b) may couple to have a third resonance frequency spectrum (e.g., as shown in FIG. 1B). Additionally or alternatively, the third resonance frequency spectrum may be different from the first resonance frequency spectrum and the second resonance frequency spectrum. In some non-limiting embodiments or aspects, when the first medical device component 102a (e.g., its first mating element 110a) is mated with the second medical device component 102b (e.g., its second mating element 110b), its antenna elements (e.g., the first antenna element 108a (e.g., its first resonant structure 104a and / or its first metal strip 106a) and the second antenna element 108b (e.g., its second resonant structure 104b and / or its 2 second metal strip 106b)) may function as a composite antenna element (e.g., by electrical contact, electromagnetic coupling, etc., as described herein). For example, when the first medical device component 102a (e.g., its first mating element 110a) is mated with the second medical device component 102b (e.g., its second mating element 110b), the first resonant structure 104a (e.g., the first spiral resonator) and the second resonant structure 104b (e.g., the second spiral resonator) may couple (e.g., by electromagnetic coupling, etc.) to form a resonant circuit having a third natural frequency. Additionally or alternatively, the third resonance frequency spectrum may include the third natural frequency of the resonant circuit.
[0100] In some non-limiting embodiments or aspects, when querying a medical device component (e.g., the first medical device component 102a and the second medical device component 102b upon fitting) fitted using the query signal 112, its antenna elements (e.g., the first antenna element 108a (e.g., its first resonant structure 104a) and the second antenna element 108b (e.g., its second resonant structure 104b)) may attenuate at least one third frequency component to form a third attenuated electromagnetic signal (e.g., the third reflected signal 114c). For example, the query signal 112 may include a multi-frequency electromagnetic signal, and when querying a medical device component fitted using the multi-frequency electromagnetic signal, its antenna elements (e.g., its first resonant structure 104a and second resonant structure 104b) may attenuate at least one third frequency component of the multi-frequency electromagnetic signal corresponding to a third resonant frequency spectrum (as further described below with respect to FIGS. 3A and 3D, for example) to form a third attenuated electromagnetic signal. In some non-limiting embodiments or aspects, the query signal 112 may supply energy to the antenna elements (e.g., the first antenna element 108a, the second antenna element 108b, etc.). Additionally or alternatively, the antenna elements may operate independently of a power source (e.g., without a power source, etc.). In some non-limiting embodiments or aspects, at least one of the antenna elements (e.g., the first antenna element 108a, the second antenna element 108b, etc.) may transmit (e.g., retransmit, backscatter, etc.) the third attenuated electromagnetic signal.
[0101] The leader device 120 may include one or more devices capable of receiving information from, for example, the server 130 (e.g., via the network 140) and / or communicating information to the server 130 or the like. Additionally or alternatively, each leader device 120 may include a device capable of receiving information from other leader devices 120 and / or communicating information to other leader devices 102 (e.g., via the network 140, another network (e.g., an ad hoc network, a local network, a private network, a virtual private network, etc.), and / or any other suitable communication technique). In some non-limiting embodiments or aspects, the leader device 120 may or may not be capable of receiving information (e.g., from another leader device 120) via a short-range wireless communication connection (e.g., a Near Field Communication (NFC) communication connection, an RFID communication connection, a Bluetooth® communication connection, a Zigbee® communication connection, etc.) and / or communicating information (e.g., to another leader device 120) via a short-range wireless communication connection.

In some non-limiting embodiments or aspects, the leader device 120 and / or the generator 122 may include at least one antenna (e.g., an antenna element, a dipole antenna, etc.). Additionally or alternatively, the generator 122 may apply an alternating current to the antenna, and the antenna may be excited by the alternating current, thereby transmitting electromagnetic waves (e.g., radio waves, microwaves, etc.). In some non-limiting embodiments or aspects, the generator 122 may include one or more devices capable of receiving information from and / or communicating information to the leader device 120, the server 130, etc. (e.g., via the network 140).
[0104] In some non-limiting embodiments or aspects, the generator 122 may transmit an interrogation signal 112 (e.g., to the medical device assembly 102). For example, the interrogation signal 112 may include a multi-frequency electromagnetic signal as described herein. In some non-limiting embodiments or aspects, the interrogation signal 112 may include a continuous wave multi-frequency electromagnetic signal with a uniform amplitude and phase.
[0105] The leader 124 may include at least one receiver (e.g., at least one device and / or circuit configured to receive electromagnetic waves). In some non-limiting embodiments or aspects, the leader device 120 and / or the leader 124 may include at least one antenna (e.g., an antenna element, a dipole antenna, etc.). Additionally or alternatively, the antenna may receive electromagnetic waves (e.g., perform eavesdropping, etc.), thereby generating an alternating current. Additionally or alternatively, such an alternating current may be applied to the receiver (e.g., by the antenna), and the receiver may extract information therefrom. For example, the receiver may determine which frequency components are present in the received signal (e.g., the received electromagnetic wave, etc.).
[0106] In some non-limiting embodiments or aspects, the leader 124 may receive at least one reflected signal (e.g., the first reflected signal 114a, the second reflected signal 114b, the third reflected signal 114c, any combination thereof, etc.) from the medical device assembly 102. For example, when querying the medical device assembly 102 using the query signal 112 (e.g., a multi-frequency electromagnetic signal), the leader 124 may receive at least one reflected signal (e.g., the first reflected signal 114a, the second reflected signal 114b, the third reflected signal 114c, any combination thereof, etc.) from (e.g., the medical device assembly 102), and the reflected signal may be an attenuated electromagnetic signal (e.g., the first medical device component 102a, the second medical device component 102b , and / or the first, second, and / or third attenuated electromagnetic signals respectively associated with the mated medical device components). In some non-limiting embodiments or aspects, each reflected signal (e.g., the first reflected signal 114a, the second reflected signal 114b, the third reflected signal 114c, any combination thereof, etc.) may include a backscattered signal, a retransmitted signal, any combination thereof, etc.
[0107] In some non-limiting embodiments or aspects, the reader 124 may detect each resonance frequency spectrum (e.g., the first medical device component 102a, the second medical device component 102b , and / or the first, second, and / or third resonance frequency spectra respectively associated with the mated medical device components) by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in the reflected signal. For example, when querying the first medical device component 102a using the query signal 112, the reader 124 may detect the first resonance frequency spectrum by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in at least one reflected signal corresponding to the first resonance frequency spectrum. Additionally or alternatively, when querying the second medical device component 102b using the query signal 112, the reader 124 may detect the second resonance frequency spectrum by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in at least one reflected signal corresponding to the second resonance frequency spectrum. Additionally or alternatively, when querying the mated medical device components (e.g., the first medical device component 102a mated with the second medical device component 102b) using the query signal 112, the reader 124 may detect the third resonance frequency spectrum by at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. in at least one reflected signal corresponding to the third resonance frequency spectrum.
[0108] In some non-limiting embodiments or aspects, the reader 124 and / or the reader device 120 may communicate the reflected signal data associated with the reflected signal (e.g., to the server 130 via a network 140, etc.). For example, the reader 124 and / or the reader device 120 may include a communication interface for such communication.
[0109] In some non-limiting embodiments or aspects, at least one leader 124 may include a plurality of leaders. Additionally or alternatively, each leader 124 may be disposed at a location (e.g., a known location, a pre-determined location, a selectable location, a pre-selected location, any combination thereof, etc.) within at least one site (e.g., at least one facility, at least one building, etc.). For example, the location of each leader 124 may be different from the locations of all other leaders 124 (e.g., each leader 124 may be at a different location within the site). In some non-limiting embodiments or aspects, the location of the medical device assembly 102 may be determined based on which of the plurality of leaders 124 detects the medical device assembly 102 (e.g., by the leader 124, the leader device 120, the server 130, etc.) (e.g., each leader 124 may have a known location, and the location of the medical device assembly 102 may be determined to be proximate to (e.g., within its operating range of) each leader 124 that detected the medical device assembly 102).
[0110] In some non-limiting embodiments or aspects, the generator 122 and / or the leader 124 may be included in a single device (e.g., the leader device 120, etc.). Additionally or alternatively, the generator 122 and / or the leader 124 may share a single antenna (e.g., the antenna of the leader device 120, etc.). In some non-limiting embodiments or aspects, the generator 122 and / or the leader 124 may be separate devices.
[0111] Server 130 may include one or more devices capable of receiving information from, and / or communicating information to, a leader device 120, a generator 122, a leader 124, etc. (e.g., via network 140). For example, server 130 may include one or more computing devices such as a server, a group of servers, etc. In some non-limiting embodiments or aspects, server 130 may be associated with a facility as described herein. In some non-limiting embodiments or aspects, server 130 may communicate with a data storage device that may be local or remote to server 130. In some non-limiting embodiments or aspects, server 130 may be capable of receiving information from the data storage device, storing information in the data storage device, communicating information to the data storage device, or retrieving information stored in the data storage device.
[0112] In some non-limiting embodiments or aspects, server 130 may include a second communication interface configured to communicate with a first communication interface (e.g., of leader 124, leader device 120, etc., via network 140, etc.). Additionally or alternatively, server 130 may be configured to receive reflected signal data via a first network. In some non-limiting embodiments or aspects, a first server is configured to store the reflected signal data (e.g., in a database, a data storage device, a memory, any combination thereof, etc.).
[0113] In some non-limiting embodiments or aspects, each type of medical device component (e.g., the first medical device component 102a, the second medical device component 102b, etc. described herein) may have a unique identifier (e.g., a stock keeping unit (SKU), etc.). Additionally or alternatively, each unique identifier may be associated with a respective resonance frequency spectrum (e.g., the first resonance frequency spectrum, the second resonance frequency spectrum, etc. described herein). In some non-limiting embodiments or aspects, each mated combination of medical device components (e.g., the first medical device component 102a mated with the second medical device component 102b, etc. described herein) may have a respective resonance frequency spectrum (e.g., the third resonance frequency spectrum, etc. described herein). In some non-limiting embodiments or aspects, each type of medical device component and / or each mated combination of medical device components may be uniquely identified based on its respective resonance frequency spectrum. For example, the server 130 may store a mapping (e.g., a database, a table, etc.) of each type of medical device component (e.g., its unique identifier) and / or each mated combination of medical device components to its respective resonance frequency spectrum (which may be pre-determined, pre-selected, etc.).
[0114] In some non-limiting embodiments or aspects, each respective unique resonance frequency spectrum may be assigned to each individual type of medical device component (e.g., the first medical device component 102a, the second medical device component 102b, etc. described herein) and / or each mated combination of medical device components based on at least one rule. For example, a first rule is that two different types of medical device components cannot be assigned to the same resonance frequency spectrum (e.g., ∀ 1≦i,j≦N, if i≠j, then F i ≠F j、 where N is the total number of possible types of medical device components, i is the number related to the first type of medical device component, F iis the resonance frequency spectrum of the first type of medical device component, j is a number related to the second type of medical device component, F j may include representing the resonance frequency spectrum of the second type of medical device component). Additionally or alternatively, the second rule is that two types of medical device components (e.g., the same or different types of medical device components) cannot have the respective resonance frequency spectra of any other two types of medical device components when they are fitted (e.g., physical connection, electrical connection, electromagnetic coupling, etc. are performed) (e.g., ∀ 1≦i,j,k,l≦N, if i≠k and / or j≠l, then Φ(S i ,S j )≠Φ(S k ,S l ), where i is a number related to the first type of medical device component, j is a number related to the second type of medical device component, k is a number related to the third type of medical device component, l is a number related to the fourth type of medical device component, S i represents the characteristics (e.g., geometric characteristics, material characteristics, etc.) of at least one resonance structure related to the first type of medical device component, S j represents the characteristics (e.g., geometric characteristics, material characteristics, etc.) of at least one resonance structure related to the second type of medical device component, S k represents the characteristics (e.g., geometric characteristics, material characteristics, etc.) of at least one resonance structure related to the third type of medical device component, S l represents the characteristics (e.g., geometric characteristics, material characteristics, etc.) of at least one resonance structure related to the fourth type of medical device component, and Φ may include representing the resonance frequency spectra of two resonance structures related to the fitted combination of two types of medical device components). Additionally or alternatively, the third rule is that one type of medical device component cannot have the respective resonance frequency spectra of any fitted combination of two types of medical device components (e.g., ∀ 1≦i,j,k≦N, F i ≠Φ(S j ,S k) Here, i is a number related to the first type of medical device component, j is a number related to the second type of medical device component, k is a number related to the third type of medical device component, F i is the resonance frequency spectrum of the first type of medical device component, S j is the characteristic (e.g., geometric characteristic, material characteristic, etc.) of at least one resonance structure related to the second type of medical device component, S k is the characteristic (e.g., geometric characteristic, material characteristic, etc.) of at least one resonance structure related to the third type of medical device component, Φ may represent the resonance frequency spectra of two resonance structures related to a mated combination of two types of medical device components). This may be included.
[0115] In some non-limiting embodiments or aspects, server 130 may perform and / or assist with inventory management. For example, thresholds (e.g., minimum numbers, etc.) may be selected (e.g., pre-determined, pre-selected, dynamically selected, etc.) for the total number of each type of medical device component at the site. Additionally or alternatively, since each type of medical device component may be uniquely identified based on its respective resonance frequency spectrum, server 130 may determine (e.g., based on reflected signal data received from multiple readers 124 within the site) the number of each type of medical device component within the site. In some non-limiting embodiments or aspects, if the total number of each type of medical device component meets a threshold (e.g., is less than a minimum number, etc.), server 130 may determine that the inventory of each type of medical device component may need to be replenished. For example, server 130 may communicate a notification (e.g., an email, a text message, etc.) indicating that the inventory of each type of medical device component may need to be replenished. Additionally or alternatively, server 130 may automatically order additional inventory of each type of medical device component (e.g., via an e-commerce transaction, etc.). Additionally or alternatively, server 130 may initiate any suitable replenishment approach (e.g., requesting a cart to travel between a warehouse, a pharmacy, and / or a treatment area site where the medical device may be utilized, etc.) as implemented within a medical institution. In some non-limiting embodiments or aspects, at least one local threshold (e.g., a minimum number, etc.) may be selected (e.g., pre-determined, pre-selected, dynamically selected, etc.) for the number of each type of medical device component at each location within the site. Additionally or alternatively, since each type of medical device component may be uniquely identified based on its respective resonance frequency spectrum, server 130 may determine (e.g., based on reflected signal data received from multiple readers 124 within the site) the number of each type of medical device component at each location within the site.In some non-limiting embodiments or aspects, if the number of each type of medical device component at each location meets a threshold (e.g., is less than a minimum number), the server 130 may determine that the inventory of each type of medical device component may need to be replenished and / or redistributed from other locations within the site. For example, the server 130 may communicate a notification and / or automatically order additional inventory as described herein.
[0116] For illustrative purposes, if a medical device component (e.g., a first medical device component 102a, a syringe, etc.) is filled with a medicament (e.g., at a pharmacy at the site) and then transported to another location (e.g., an operating room at the site), the medical device component can be detected during transportation and / or at the destination location by at least one reader 124 (e.g., any one of one or more readers 124 that can be disposed along a path along which the medical device component can move, and / or any one of one or more readers 124 that can be disposed at the destination location). Thus, the position of the medical device component can be determined and / or stored as described herein. For example, the position of each reader 124 that most recently detected the medical device component can be known (e.g., preselected, predetermined, etc.). Additionally or alternatively, when the medical device component reaches the destination location, it can be detected by at least one reader 124 disposed within or near the destination location (e.g., an operating room, etc.). Additionally or alternatively, if a medicament-filled medical device component is intended to be connected to a second medical device component (e.g., a second medical device component 102b, a catheter, etc.) to deliver the medicament to a patient, for example, the fitting between the medicament-filled medical device component and the second medical device component can be detected as described herein. Additionally or alternatively, after detecting the resonance frequency spectrum associated with the fitting between the medicament-filled medical device component and the second medical device component, if the at least one reader 124 later (e.g., within a predetermined and selected (e.g., predetermined, preselected, dynamically selected, etc.) period, etc.) detects a first resonance frequency spectrum associated with the medical device component and a second resonance frequency spectrum associated with the second medical device component (e.g., stops detecting the resonance frequency spectrum associated with the fitting between these medical device components), such an opening between the medical device components can be determined (e.g., detected, inferred, assumed, etc.).
[0117] In some non-limiting embodiments or aspects, the server 130 (and / or the leader device 120 and / or the leader 124) may perform and / or assist in compliance determination. For example, the fitting of the first medical device component 102a and the second medical device component 102b may be detected based on detecting a third frequency spectrum (and / or the lack of fitting between the first medical device component 102a and the second medical device component 102b may be detected based on detecting at least one of the first frequency spectrum and / or the second frequency spectrum without detecting the third frequency spectrum), so that the connection and / or disconnection of the medical device components can be determined (e.g., detected, monitored, recorded, stored, etc.). For example, based on the reflected signal data, the server 130 (and / or the leader device 120, and / or the leader 124) may determine whether the first medical device component 102a and the second medical device component 102b are fitted, and / or may store the reflected signal data together with time data (e.g., timestamp, date and time data, etc.). In some non-limiting embodiments or aspects, the determination of the fitting (and / or the lack of fitting) between the first medical device component 102a and the second medical device component 102b may be compared with guidelines and / or a defined treatment protocol to determine compliance therewith (e.g., if the guidelines and / or the defined treatment protocol require a connection between the two components over a predetermined time (e.g., the amount of time for flushing an IV line by connecting a syringe filled with saline, the amount of time for fluid to be injected through an IV line by connecting a container of such fluid (e.g., a bag) to the IV line, etc.), the timestamp associated with the fitting or lack of fitting between the medical device components may be compared with the time period of the guidelines and / or the defined treatment protocol). For example, such guidelines and / or defined treatment protocols may be stored in a database (e.g., local or remote to the server 130).
[0118] In some non-limiting embodiments or aspects, the operating frequencies of the first antenna element 108a (e.g., its first resonant structure 104a), the second antenna element 108b (e.g., its second resonant structure 104b), the leader device 120, the generator 122, the leader 124, etc. may include any suitable frequency range. For example, the operating frequency may be in the ultra-wideband (UWB), within the range of 3 to 10 GHz, etc. In some non-limiting embodiments or aspects, the operating range (e.g., distance, etc.) of the first antenna element 108a (e.g., its first resonant structure 104a), the second antenna element 108b (e.g., its second resonant structure 104b), the leader device 120, the generator 122, the leader 124, etc. may include any suitable distance. For example, the operating range (e.g., distance, etc.) may be less than 5 m, less than 1 m, less than 0.7 m, etc. In some non-limiting embodiments or aspects, the operating temperature range of the first antenna element 108a (e.g., its first resonant structure 104a), the second antenna element 108b (e.g., its second resonant structure 104b), the leader device 120, the generator 122, the leader 124, etc. may include any suitable temperature range. For example, the operating temperature range may include from -20°C to 80°C, etc.
[0119] In some non-limiting embodiments or aspects, in addition to RFID tags (e.g., RFID tags including integrated circuits (ICs), ASICs, etc.), the resonant structures described herein (e.g., the first antenna element 108a including at least one first resonant structure 104a, the second antenna element 108b including at least one second resonant structure 104b, etc.) may be used. For example, the resonant structures described herein (e.g., the first antenna element 108a including at least one first resonant structure 104a, the second antenna element 108b including at least one second resonant structure 104b, etc.) may be used to detect the fitting of medical device components, while at least one RFID tag may be used to identify each individual medical device component, etc.
[0120] Network 140 may include one or more wired and / or wireless networks. For example, network 140 may include a cellular network (e.g., a Long-Term Evolution (LTE) network, a 3rd generation (3G) network, a 4th generation (4G) network, a 5th generation (5G) network, a Code Division Multiple Access (CDMA) network, etc.), a Public Land Mobile Network (PLMN), a Local Area Network (LAN), a Wide Area Network (WAN), a Metropolitan Area Network (MAN), a telephone network (e.g., a Public Switched Telephone Network (PSTN)), a private network (e.g., a private network associated with a facility), an ad hoc network, an intranet, the Internet, an optical fiber-based network, a computer network, a cloud computing network, etc., and / or a combination of these or other types of networks.

Additional systems, devices, and / or networks, fewer systems, devices, and / or networks, different systems, devices, and / or networks, and / or systems, devices, and / or networks configured separately from those shown in FIG. 1 may exist. Further, two or more of the systems or devices shown in FIG. 1 may be implemented within a single system or device, or a single system or device shown in FIG. 1 may be implemented as a plurality of distributed systems or devices. Additionally or alternatively, a set of systems (e.g., one or more systems) or a set of devices (e.g., one or more devices) of the environment 100 may perform one or more functions described as being performed by another set of systems or another set of devices of the environment 100.
[0122] Next, referring to FIGS. 2A - 2D, FIGS. 2A - 2D are diagrams of an exemplary implementation 200 of a non - limiting embodiment or aspect related to the environment 100 shown in FIG. 1. As shown in FIGS. 2A and 2B, the implementation 200 may include a spiral resonator 204, a microstrip 206, a substrate 216, and / or a ground plane 218. In some non - limiting embodiments or aspects, the spiral resonator 204 may be the same as or similar to the first resonant structure 104a and / or the second resonant structure 104b. In some non - limiting embodiments or aspects, the microstrip 206 may be the same as or similar to the first metal strip 106a and / or the second metal strip 106b.
[0123] In some non - limiting embodiments or aspects, the spiral resonator 204, the microstrip 206, and / or the ground plane 218 may include (e.g., be formed of) a conductive material (e.g., a conductor, a metallic material, a conductive ink, a metal ribbon (e.g., an amorphous metal ribbon), etc.). For example, each of the spiral resonator 204, the microstrip 206, and / or the ground plane 218 may include (e.g., be formed of) the same conductive material. Additionally or alternatively, at least one of the spiral resonator 204, the microstrip 206, and / or the ground plane 218 may include (e.g., be formed of) a different conductive material from the others. In some non - limiting embodiments or aspects, at least one of the spiral resonator 204, the microstrip 206, and / or the ground plane 218 may include (e.g., be formed of) aluminum, copper, gold, silver, aluminum oxide, conductive ink, a transparent conductive material, etc.
[0124] In some non-limiting embodiments or aspects, the substrate 216 may include (e.g., be formed from) the material of at least a portion of each medical device component (e.g., the first medical device component 102a, the second medical device component 102b, etc.). Additionally or alternatively, the substrate 216 may include (e.g., be formed from) a tag (e.g., fixed to each medical device component). For example, the tag may include (e.g., be formed from) a dielectric material (e.g., plastic, flexible polymer, polypropylene, polyethylene terephthalate (PET), paper, transparent dielectric material, etc.).

[0183] In some non-limiting embodiments or aspects, when querying the medical device component 602 using a query signal, the antenna element 608 (e.g., its resonant structure 604) can attenuate at least one first frequency component to form a first attenuated electromagnetic signal (e.g., a first reflected signal), as described herein. For example, the query signal can include a multi-frequency electromagnetic signal, and when querying the medical device component 602 using the multi-frequency electromagnetic signal, the antenna element 608 (e.g., its resonant structure 604) can attenuate at least one first frequency component of the multi-frequency electromagnetic signal corresponding to a first resonant frequency spectrum to form a first attenuated electromagnetic signal, as described herein.
[0184] In some non-limiting embodiments or aspects, when querying the medical device component 602 using a query signal, the longitudinal antenna element 668 (e.g., its scale marking resonant structure 664) can attenuate at least one second frequency component to form a second attenuated electromagnetic signal (e.g., a second reflected signal), as described herein.

[0185] In some non-limiting embodiments or aspects, when the medical device component 602 (e.g., its mating element 610) is mated to a second medical device component (e.g., its second mating element), as described herein, the antenna element 608 (e.g., its resonant structure 604) may couple to a second antenna element (e.g., its second resonant structure) of the second medical device component to have a third resonant frequency spectrum. Additionally or alternatively, the third resonant frequency spectrum may be different from the first resonant frequency spectrum and the second resonant frequency spectrum, as described herein. In some non-limiting embodiments or aspects, when querying the mated medical device components using a query signal, as described herein, the antenna element may attenuate at least one third frequency component to form a third attenuated electromagnetic signal (e.g., a third reflected signal).
[0186] Referring now to FIGS. 6B and 6C, FIGS. 6B and 6C are graphs of exemplary frequency spectra of non-limiting embodiments or aspects related to the implementation 600 shown in FIG. 6A. As shown in FIGS. 6B and 6C, the graph may have a horizontal axis associated with frequency (f) and a vertical axis associated with amplitude (A).
[0187] Referring to FIG. 6B, the query signal 612 may include a multi-frequency electromagnetic signal, as described herein. For example, the query signal 612 may include a continuous wave multi-frequency electromagnetic signal with a uniform amplitude and phase over a range of frequencies. In some non-limiting embodiments or aspects, the query signal 612 may be the same as or similar to the query signal 112.
[0188] Referring to FIG. 6C, the second reflected signal 614 may include a second attenuated electromagnetic signal from the longitudinal antenna element 668, as described herein. For example, the second reflected signal 614 may include at least one of amplitude attenuation, phase jump, frequency attenuation, any combination thereof, etc. corresponding to a second resonance frequency spectrum (e.g., associated with the longitudinal antenna element 668 and / or its scale marking resonance structure 664) as described herein. For purposes of illustration, as shown in FIG. 6C, the second reflected signal 614 may include amplitude attenuation around the natural frequency of each of the plurality of scale marking resonance structures 664. For example, the second reflected signal 614 may include a first amplitude attenuation around a first natural frequency f 1 associated with (e.g., the first scale marking resonance structure 664, etc.), a second amplitude attenuation around a second natural frequency f 2 associated with (e.g., the second scale marking resonance structure 664, etc.), an nth amplitude attenuation around an nth natural frequency f n associated with (e.g., the nth scale marking resonance structure 664, etc.), and any combination thereof.
[0189] In some non-limiting embodiments or aspects, each type of medical device component (e.g., the first medical device component 102a, the second medical device component 102b, etc. described herein) may have a unique identifier (e.g., a stock keeping unit (SKU), etc.). Additionally or alternatively, each of the N possible scale marking resonator structures 664 may have a unique natural frequency. In some non-limiting embodiments or aspects, each respective type of medical device component may be uniquely identified based on a unique subset of up to n scale marking resonator structures 664 (e.g., n may be less than or equal to N). For example, each of the N possible scale marking resonator structures 664 may be associated with 1 bit, and when each respective subset includes one of each of the N possible scale marking resonator structures 664 (e.g., when the second reflected signal 614 includes the natural frequency of one of each of the N possible scale marking resonator structures 664), the presence of one of each of the N possible scale marking resonator structures 664 may be associated with a first logical value (e.g., 1, 0, etc.). Additionally or alternatively, when each respective subset does not include one of each of the N possible scale marking resonator structures 664 (e.g., when the second reflected signal 614 does not include the natural frequency of one of each of the N possible scale marking resonator structures 664), the absence of one of each of the N possible scale marking resonator structures 664 may be associated with a second logical value (e.g., 0, 1, etc., respectively). Thus, each unique natural frequency may be the same or similar to a logical bit (e.g., the bit may be 1 (present), 0 (absent), etc.). In some non-limiting embodiments or aspects, each possible arrangement of the subset of up to n scale marking resonator structures 664 may be associated with a number that includes a plurality of bits, and each bit may be associated with 1 (e.g., the respective natural frequency is present) or 0 (the respective natural frequency is absent), etc.Additionally or alternatively, each possible arrangement of a subset of up to n scale marking resonator structures 664 (e.g., a number including a plurality of bits associated therewith) can be associated with each respective one of a plurality of unique identifiers for a plurality of types of medical device components.

In some non-limiting embodiments or aspects, the total number of possible bits can be up to 35 bits. Additionally or alternatively, the bit density per unit can be up to 5.88 bits / cm (e.g., based on geometric characteristics of resonator structures 664, material characteristics of resonator structures 664, operating frequencies of resonator structures 664, etc.). 2 , up to 5.22 bits / cm 2 , up to 4.17 bits / cm 2 , up to 3.56 bits / cm 2 , up to 3 bits / cm 2 , up to 2.86 bits / cm 2 , up to 2.37 bits / cm 2 , up to 2.11 bits / cm 2 , up to 1.25 bits / cm 2 , up to 1.14 bits / cm 2 , up to 0.77 bits / cm 2 , up to 0.61 bits / cm 2 , up to 0.2 bits / cm 2 , up to 0.1 bits / cm 2 and the like can be included.
