Description

[0001] Cross-references to related applications

[0002] This application claims priority to U.S. Provisional Application No. 63 / 021,496, filed May 7, 2020, entitled “Apparatus, System and Method for Detecting Multiple Medical Device Components and / or Their Combinations,” the entire disclosure of which is incorporated herein by reference. Background Technology 1. Technical Field

[0004] The subject matter of this disclosure generally relates to apparatus, systems, and methods for detecting multiple medical device components, and in some specific embodiments or aspects, to an apparatus, system, and method for detecting the mating of multiple medical device components.

[0005] 2. Technical considerations

[0006] Some technologies used for product identification may include machine-readable optical tags (e.g., barcodes, and / or quick response (QR) codes). For example, attaching optical tags to a product and / or its packaging (e.g., by adhesive bonding, and / or by direct printing onto the product and / or packaging) may be relatively inexpensive. However, readers of such optical tags may use relatively complex optical systems, may require a line of sight for operation (e.g., between the reader and the optical tag), may require manual alignment and / or manual triggering, and / or may be difficult to automate.

[0007] Other technologies used for product identification may include radio frequency identification (RFID) tags. For example, such RFID tags may include application-specific integrated circuits (ASICs) and antennas. The antennas can allow data to be transmitted and / or received via radio communication, which may eliminate the need for operator line of sight. The ASICs can allow data to be stored on, read from, and / or written to the RFID tag. However, such RFID tags can be relatively expensive, at least in part due to the cost and / or time required to manufacture the ASIC. Furthermore, while the ability to operate without line of sight may be preferred for automation, the increased cost of RFID tags (e.g., compared to optical tags) may not be suitable (e.g., for the manufacture, identification, and / or tracking of inexpensive and / or disposable products, such as inexpensive and / or disposable medical device components).

[0008] Furthermore, while certain technologies (e.g., optical tags or RFID tags) can be used to identify individual products, these technologies may not be able to detect the combination of multiple products (e.g., the combination of multiple medical device components). Summary of the Invention

[0091] It should be understood that, unless expressly stated to the contrary, this disclosure may have various alternative variations and sequences of steps. 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 and non-limiting embodiments or aspects. Therefore, specific dimensions and other physical characteristics relating to the embodiments or aspects disclosed herein should not be considered limiting.

[0092] For the purposes described below, the terms “end,” “upper,” “lower,” “right,” “left,” “vertical,” “horizontal,” “top,” “bottom,” “lateral,” “longitudinal,” and their derivatives, shall relate to the orientation of the subject matter of this disclosure in the accompanying drawings. However, it should be understood that, unless explicitly stated to the contrary, the subject matter of this disclosure may have various alternative variations and sequences of steps. 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 of this disclosure. Therefore, unless otherwise stated, specific dimensions and other physical characteristics relating to the embodiments or aspects disclosed herein should not be considered limiting.

[0093] Unless explicitly stated otherwise, aspects, parts, elements, structures, actions, steps, functions, and / or instructions used herein should not be construed as critical or essential. Furthermore, as used herein, the quantifiers “a” and “an” are intended to include one or more items and may be used interchangeably with “one or more” and “at least one.” Additionally, as used herein, the term “set” is intended to include one or more items (e.g., related items, unrelated items, and / or combinations of related and unrelated items), and may be used interchangeably with “one or more” or “at least one.” Where only one item is referred to, the term “a” or a similar word is used. Furthermore, as used herein, the terms “has,” “have,” and / or “having” are intended to be open-ended terms. Additionally, unless explicitly stated otherwise, the phrase “based on” is intended to mean “at least partially based on.”

[0094] As used herein, the terms "communication" and "communicate" can refer to the receipt, reception, transmission, transfer, and / or provision of information (e.g., data, signals, messages, instructions, and / or commands). For a unit communicating with another unit (e.g., a device, system, component of a device or system, and / or a combination thereof), it means that the unit is able to receive information directly or indirectly from the other unit, and / or send information directly or indirectly to the other unit. This can refer to a substantially wired and / or wireless direct or indirect connection (e.g., a direct communication connection, and / or an indirect communication connection). Furthermore, two units can communicate with each other even if the transmitted information can be modified, processed, forwarded, and / or routed between the first and second units. For example, the first unit can communicate with the second unit even if it passively receives information and does not actively send information to the second unit. As another example, the first unit can communicate with the second unit if at least one intermediate unit (e.g., a third unit located between the first and second units) processes information received from the first unit and transmits the processed information to the second unit. In some non-limiting embodiments or aspects, a message may refer to a network data packet (e.g., a data packet, etc.) that includes data. It will be appreciated that many other configurations are possible.

[0095] As used herein, the term "server" can refer to one or more computing devices, such as processors, storage devices, and / or similar computer components, that communicate with multiple client devices and / or multiple other computing devices via a network (e.g., the Internet or a private network), and in some examples, that similar computer component facilitates communication between multiple other servers and / or multiple client devices. It will be appreciated that various other configurations are possible. Furthermore, as used herein, references to "server" or "processor" can refer to a previously stated server and / or processor, different servers and / or processors, and / or combinations of servers and / or processors, stated to perform a prior step or function. For example, as used in the specification and claims, a first server and / or a first processor stated to perform a first step or function can refer to the same or different server and / or the same or different processor stated to perform a second step or function.

[0096] This document describes some non-limiting embodiments or aspects in conjunction with thresholds. As used herein, satisfying a threshold can mean that a value is greater than the threshold, a value exceeds the threshold, a value is higher than the threshold, a value is greater than or equal to the threshold, a value is less than the threshold, a value is lower than the threshold, a value is less than or equal to the threshold, a value is equal to the threshold, etc.

[0097] Non-limiting embodiments or aspects of this disclosure relate to devices, systems, and methods for detecting multiple medical device components, including but not limited to detecting the mating of multiple medical device components. For example, a non-limiting embodiment or aspect of this disclosure provides a first medical device component and a second medical device component, the first having at least one first resonant structure (having a first resonant spectrum), the second having at least one second resonant structure (having a second resonant spectrum), and, when the first and second medical device components mate, the first and second resonant structures combine to have a third resonant spectrum (different from the first and second resonant spectra). These embodiments or aspects provide techniques and systems capable of wirelessly (e.g., via radio communication, etc.) detecting (e.g., identifying, etc.) multiple individual medical device components and / or detecting their mating combinations, which are advantageous and do not require line of sight. For example, because no line of sight is required, these medical devices can be operated by a clinician in any manner (e.g., any orientation relative to a reader, etc.) and can still be detected. Additionally or alternatively, these embodiments or aspects provide a variety of techniques and systems that allow such wireless detection (e.g., identification, etc.) to be performed without complex circuitry (e.g., integrated circuits, application-specific integrated circuits (ASICs), memories, and / or processors, etc.) formed in and / or attached to components of a medical device. These techniques and systems can reduce (e.g., lower) the time, amount of resources, number of different resources, and / or costs associated with the production and / or use of the subject matter of this disclosure (e.g., compared to radio frequency identification (RFID) tags, etc.), and can improve reliability (e.g., due to the absence of complex circuitry that may be damaged and / or aged). Additionally or alternatively, these embodiments or aspects provide a variety of techniques and systems that allow such wireless detection (e.g., identification, etc.) to be performed without power supply formed in and / or attached to components of a medical device. These techniques and systems can reduce the cost and / or complexity of production and / or use. Additionally or alternatively, these embodiments or aspects provide a variety of technologies and systems more suitable for automation (e.g., due to wireless operation, reduced (e.g., eliminated and / or reduced) line-of-sight and / or alignment requirements, and / or reduced production and / or usage time and / or costs, etc.). Additionally or alternatively, these embodiments or aspects provide a variety of technologies and systems capable of detecting the mating (e.g., proper connection, and / or alignment, etc.) of two or more medical device components. In this regard, these technologies and systems may be useful for prescriptive tracking (e.g., by tracking (e.g., detecting, and / or recording, etc.) the connection and / or disconnection of multiple medical device components (e.g., syringes and vascular access devices).For example, connections and / or disconnections can be compared with rules (e.g., guidelines, and / or prescribed treatment protocols, etc.) to determine the prescriptivity of the connection and / or disconnection. Additionally or alternatively, these embodiments or aspects provide various technologies and systems capable of locating and / or tracking each medical device component within a facility (e.g., using multiple readers located in different (e.g., known) locations within the facility, each reader capable of detecting one or more medical device components nearby (e.g., within the reader's operating range, etc.). Additionally or alternatively, these embodiments or aspects provide various technologies and systems for implementing inventory management and / or logistics (e.g., since the quantity of each type of medical device component and / or the location of each type of medical device component within the facility can be determined at a given time, the stock of at least one type of medical device component can be replenished and / or reallocated as needed (e.g., based on meeting thresholds associated with its stock level, etc.). Additionally or alternatively, these embodiments or aspects provide a variety of techniques and systems capable of preventing counterfeiting (e.g., counterfeit medical device components may lack one or more correct resonant structures and / or one or more correct resonant spectra, and / or have one or more incorrect resonant structures and / or one or more incorrect resonant spectra).

[0098] For illustrative purposes, although the subject matter of this disclosure is described in the following description with respect to apparatus, systems, and methods for detecting multiple medical device components (e.g., detecting the mating of multiple medical device components), those skilled in the art will recognize that the scope of this disclosure is not limited to these illustrative embodiments or aspects. For example, the apparatus, systems, and methods described herein can be used with a variety of settings, such as identifying these products and / or detecting mating (e.g., the mating of these products, and / or the mating of multiple components of these products) in any setting suitable for using multiple products (e.g., suitable for manufacturing, shipping, inventory management, retail, and / or sourcing products).

[0099] For reference Figure 1A and Figure 1B , Figure 1A and Figure 1B This is a schematic diagram of a non-limiting embodiment or aspect of environment 100, in which the apparatus, system, and / or method described herein may be implemented.

[0102] 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 resonant spectrum. For example, the first antenna element 108a may include at least one first resonant structure 104a, and each first resonant structure 104a may have a resonant spectrum (e.g., a first resonant 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 resonant structure 104a may include at least one helical resonator (e.g., a first helical resonator).

In some non-limiting embodiments or aspects, the first helical resonator may include a first helical metal conductor (e.g., formed by the first helical metal conductor), the first helical metal conductor being adjacent to the first metal strip 106a (e.g., the first metal strip of the first antenna element 108a of the first medical device component 102a). Additionally or alternatively, the first helical-shaped metal conductor may have a first inductance, a first capacitance, and / or a first resistance. In some non-limiting embodiments or aspects, the first inherent frequency may be based on the first inductance, the first capacitance, and / or the first resistance. Additionally or alternatively, the first inherent frequency, the first inductance, the first capacitance, and / or the first resistance may be based on the geometry and / or material properties of the first helical resonator (e.g., as described below regarding...). Figure 2A and Figure 2B (As further described). In some non-limiting embodiments or aspects, the first resonant structure 104a may include at least one first metal strip (e.g., an amorphous metal strip). Additionally or alternatively, the first resonant spectrum may include a first natural frequency (e.g., a resonant frequency, etc.) of the first metal strip (e.g., an amorphous metal strip, etc.). For example, the first natural frequency f (e.g., a resonant frequency, etc.) of the first metal strip (e.g., an amorphous metal strip) may be determined based on the equation f≈(1 / 2πl)√(Y / ρ), where l may represent length, Y may represent Young's modulus, and ρ may represent density.

[0103] In some non-limiting embodiments or aspects, when accessing the first medical device component 102a using access 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., a first reflected signal 114a). For example, access signal 112 may include a multi-frequency electromagnetic signal, and when accessing 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 in the multi-frequency electromagnetic signal corresponding to the first resonant spectrum to form a first attenuated electromagnetic signal (e.g., as described below regarding...). Figure 3A and Figure 3B (As further described). In some non-limiting embodiments or aspects, the access signal 112 may excite 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) may operate independently of a power source (e.g., operate without a power source, etc.). In some non-limiting embodiments or aspects, the first antenna element 108a may transmit (e.g., retransmission, and / or backscattering, etc.) a first attenuated electromagnetic signal.

[0104] In some non-limiting embodiments or aspects, a first metal strip 106a (e.g., at least a portion of the first metal strip) may be circumferentially arranged around a first medical device component 102a. Alternatively or additionally, the first metal strip 106a (e.g., at least a portion of the first metal strip) may be longitudinally arranged along the first medical device component 102a (e.g., axially, and / or parallel to the axis of the first medical device component, etc.). In some non-limiting embodiments or aspects, at least a portion of the first metal strip 106a may be located at one end (e.g., the distal end, etc.) of the first medical device component 102a (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 make electrical contact and / or electromagnetic coupling with the second metal strip 106b).

[0105] In some non-limiting embodiments or aspects, at least one first resonant structure 104a may include a plurality of first resonant structures 104a.

Additionally or alternatively, the first receiving antenna element and the first transmitting antenna element may 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 may be cross-polarized (e.g., to reduce interference between received signals (e.g., access signal 112) and reflected signals (e.g., first reflected signal 114a), etc.). For example, the first receiving antenna element may be orthogonally arranged to the first transmitting antenna element (e.g., the first receiving antenna element (e.g., its surface) may be arranged (e.g., substantially arranged, and / or mainly arranged, etc.) in a first plane, and the first transmitting antenna element (e.g., its surface) may be arranged (e.g., substantially arranged, and / or mainly arranged, etc.) in a second plane orthogonal to the first plane).

For example, the first mating element 110a may include any element configured to mate the first medical device component 102a with a second medical device component 102b (e.g., its second mating element 110b). In some non-limiting embodiments or aspects, the first mating element 110a may include a Luer connector (e.g., a male Luer connector, and / or a female Luer connector, etc.). For example, the first mating element 110a may include a male Luer connector, and the second mating element 110b may include a corresponding female Luer connector. In some non-limiting embodiments or aspects, the first antenna element 108a (e.g., its first resonant structure 104a and / or its first metal strip 106a) may be provided with the first mating element 110a (e.g., a male Luer connector, etc.).

Figure 7(As further described). For example, each of the second receiving antenna element and the second transmitting antenna element may include a disc-shaped metal conductor. Additionally or alternatively, the second receiving antenna element and the second transmitting antenna element may be attached to opposite ends of the second metal strip 106b. In some non-limiting embodiments or aspects, the second receiving antenna element and the second transmitting antenna element may be cross-polarized (e.g., to reduce interference between the received signal (e.g., access signal 112) and the reflected signal (e.g., the second reflected signal 114b), etc.). For example, the second receiving antenna element may be orthogonally arranged to the second transmitting antenna element (e.g., the second receiving antenna element (e.g., its surface) may be arranged (e.g., substantially arranged, and / or mainly arranged, etc.) in a first plane, and the second transmitting antenna element (e.g., its surface) may be arranged (e.g., substantially arranged, and / or mainly arranged, etc.) in a second plane orthogonal to the first plane).

[0118] In some non-limiting embodiments or aspects, the second medical device component 102b (e.g., its second antenna element 108b) may include a second receiving / transmitting antenna element. For example, the second receiving / transmitting antenna element may include a disc-shaped metal conductor.

[0119] In some non-limiting embodiments or aspects, at least a portion of the second antenna element 108b (e.g., the second resonant structure 104b, the second metal strip 106b, and / or any combination thereof) may be formed on (e.g., printed on, etc.) the second medical device component 102b. Additionally or alternatively, at least a portion of the second antenna element 108b (e.g., the second resonant structure 104b, the second metal strip 106b, and / or any combination thereof) may be adhered to the second medical device component 102b (e.g., mounted to the second medical device component, adhered to the second medical device component, and / or includes an adhesive label applied to the second medical device component, etc.).

[0120] In some non-limiting embodiments or aspects, the second medical device component 102b may include a second mating element 110b. For example, the second mating element 110b may include any element configured to mate the second medical device component 102b with the first medical device component 102a (e.g., its first mating element 110a). In some non-limiting embodiments or aspects, the second mating element 110b may include a Luer connector (e.g., a male Luer connector, and / or a female Luer connector, etc.). For example, the second mating element 110b may include a female Luer connector, and the first mating element 110a may include a corresponding male Luer connector. In some non-limiting embodiments or aspects, the second antenna element 108b (e.g., its second resonant structure 104b and / or second metal strip 106b) may be provided with a second mating element 110b (e.g., a female Luer connector, etc.). For example, at least a portion of the second antenna element 108b (e.g., at least a portion of the second resonant structure 104b and / or the second metal strip 106b) may surround the second mating element 110b and / or be positioned close to the second mating element. Additionally or alternatively, at least a portion of the second antenna element 108b (e.g., at least a portion of the second resonant structure 104b and / or the second metal strip 106b) may be positioned sufficiently close to the second mating element 110b such that when the second medical device component 102b (e.g., its second mating element 110b) is mated to the first medical device component 102a (e.g., its first mating element 110a), the second antenna element 108b (e.g., the second resonant structure 104b and / or the second metal strip 106b) may make electrical contact and / or electromagnetic coupling with the first antenna element 108a (e.g., the first resonant structure 104a and / or the first metal strip 106a).

[0121] In some non-limiting embodiments or aspects, when a first medical device component 102a (e.g., its first mating element 110a) is mated to a 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) can be combined to have a third resonant spectrum (e.g., as shown in the image). Figure 1B(As shown). Additionally or alternatively, the third resonant spectrum may differ from the first and second resonant spectra. In some non-limiting embodiments or aspects, when a first medical device component 102a (e.g., its first mating element 110a) is mated to a second medical device component 102b (e.g., its second mating element 110b), the antenna elements of the first and second medical device components (e.g., the first antenna element 108a (e.g., its first resonant structure 104a and / or the first metal strip 106a) and the second antenna element 108b (e.g., its second resonant structure 104b and / or the first metal strip 106b)) may serve as combined antenna elements (e.g., combined antenna elements due to electrical contact and / or electromagnetic coupling as described herein). For example, when a first medical device component 102a (e.g., its first mating element 110a) is mated to a second medical device component 102b (e.g., its second mating element 110b), the first resonant structure 104a (e.g., a first helical resonator) and the second resonant structure 104b (e.g., a second helical resonator) can be coupled (e.g., electromagnetic coupling, etc.) to form a resonant circuit having a third inherent frequency. Additionally or alternatively, the third resonant spectrum may include the third inherent frequency of the resonant circuit.

[0122] In some non-limiting embodiments or aspects, when accessing a mated medical device component using access signal 112 (e.g., when the first medical device component 102a is mated with the second medical device component 102b), the antenna elements of the mated medical device component (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)) can attenuate at least one third frequency component to form a third attenuated electromagnetic signal (e.g., a third reflected signal 114c). For example, access signal 112 may include a multi-frequency electromagnetic signal, and when accessing a mated medical device component using this multi-frequency electromagnetic signal, the antenna elements of the mated medical device component (e.g., its first resonant structure 104a and the second resonant structure 104b) can attenuate at least one third frequency component in the multi-frequency electromagnetic signal corresponding to the third resonant spectrum to form a third attenuated electromagnetic signal (e.g., as described below regarding...). Figure 3A and 3D(As further described). In some non-limiting embodiments or aspects, the access signal 112 may excite antenna elements (e.g., first antenna element 108a, and / or second antenna element 108b, etc.). Additionally or alternatively, multiple antenna elements may operate independently of a power source (e.g., operate without a power source, etc.). In some non-limiting embodiments or aspects, at least one of these antenna elements (e.g., first antenna element 108a, and / or second antenna element 108b, etc.) may transmit (e.g., retransmission, and / or backscattering, etc.) a third attenuated electromagnetic signal.

Additionally or alternatively, each reader device 120 may include a device capable of receiving information from other reader devices 120, and / or transmitting information to such other readers (e.g., via network 140, other networks (e.g., ad hoc networks, local networks, private networks, and / or virtual private networks, etc.), and / or any other suitable communication technology). In some non-limiting embodiments or aspects, reader device 120 may or may not be able to connect via short-range wireless communication (e.g., near-field communication (NFC) communication connection, RFID communication connection, Bluetooth). Communication connection, and / or (Zifeng) (e.g., information from another reader device 120) via communication connections, and / or transmit information via short-range wireless communication connections (e.g., transmit information to another reader device 120).

[0125] Generator 122 may include at least one transmitter (e.g., at least one device and / or circuitry configured to generate and / or transmit electromagnetic waves, such as a signal generator, radio frequency (RF) transmitter, microwave transmitter, analog transmitter, digital transmitter, and / or any combination thereof). Additionally or alternatively, generator 122 may generate alternating current (e.g., RF AC, and / or microwave AC, etc.). In some non-limiting embodiments or aspects, reader device 120 and / or generator 122 may include at least one antenna (e.g., an antenna element, and / or a dipole antenna, etc.). Additionally or alternatively, generator 122 may apply alternating current to the antenna, which can be excited by the alternating current to transmit electromagnetic waves (e.g., radio waves, and / or microwaves, etc.). In some non-limiting embodiments or aspects, generator 122 may include one or more devices capable of receiving information from reader device 120 and / or server 130, and / or transmitting information to the reader device and / or server (e.g., via network 140).

[0126] In some non-limiting embodiments or aspects, generator 122 may transmit access signal 112 (e.g., transmit the access signal to medical device component 102). For example, access signal 112 may include a multi-frequency electromagnetic signal, as described herein. In some non-limiting embodiments or aspects, access signal 112 may include a continuous wave multi-frequency electromagnetic signal having uniform amplitude and phase.

[0127] Reader 124 may include at least one receiver (e.g., at least one device and / or circuitry configured to receive electromagnetic waves). In some non-limiting embodiments or aspects, reader device 120 and / or reader 124 may include at least one antenna (e.g., an antenna element, and / or a dipole antenna, etc.). Additionally or alternatively, the antenna may receive (e.g., intercept, etc.) electromagnetic waves, thereby generating alternating current. Additionally or alternatively, the alternating current may be applied to a receiver (e.g., applied to the receiver via the antenna), from which information may be extracted. For example, the receiver may determine the frequency components present in the received signal (e.g., received electromagnetic waves, etc.).

[0128] In some non-limiting embodiments or aspects, the reader 124 may receive at least one reflected signal from the medical device component 102 (e.g., a first reflected signal 114a, a second reflected signal 114b, a third reflected signal 114c, and / or any combination thereof). For example, when accessing the medical device component 102 using an access signal 112 (e.g., a multi-frequency electromagnetic signal), the reader 124 may (e.g., from the medical device component 102) receive at least one reflected signal (e.g., a first reflected signal 114a, a second reflected signal 114b, a third reflected signal 114c, and / or any combination thereof), which may include attenuated electromagnetic signals (e.g., a first attenuated electromagnetic signal associated with a first medical device component 102a, a second attenuated electromagnetic signal associated with a second medical device component 102b, and / or a third attenuated electromagnetic signal associated with a mated medical device component), as described herein. In some non-limiting embodiments or aspects, each reflected signal (e.g., first reflected signal 114a, second reflected signal 114b, third reflected signal 114c, and / or any combination thereof) may include a backscattered signal, a retransmission signal, and / or any combination thereof.

[0129] In some non-limiting embodiments or aspects, the reader 124 can detect a corresponding resonance spectrum (e.g., a first attenuated electromagnetic signal associated with the first medical device component 102a, a second attenuated electromagnetic signal associated with the second medical device component 102b, and / or a third attenuated electromagnetic signal associated with the mated medical device component) through at least one of the amplitude attenuation, phase transition, frequency attenuation, and / or any combination thereof in one or more reflected signals. For example, when accessing the first medical device component 102a using the access signal 112, the reader 124 can detect the first resonance spectrum through at least one of the amplitude attenuation, phase transition, frequency attenuation, and / or any combination thereof in one or more reflected signals corresponding to the first resonance spectrum. Additionally or alternatively, when accessing the second medical device component 102b using the access signal 112, the reader 124 can detect the second resonance spectrum through at least one of the amplitude attenuation, phase transition, frequency attenuation, and / or any combination thereof in one or more reflected signals corresponding to the second resonance spectrum. Additionally or alternatively, when accessing a mated medical device component (e.g., a first medical device component 102a mated with a second medical device component 102b) using access signal 112, reader 124 may detect the third resonant spectrum by at least one of the following: amplitude attenuation, phase jump, frequency attenuation, and / or any combination thereof, in at least one reflected signal corresponding to the third resonant spectrum.

[0130] In some non-limiting embodiments or aspects, reader 124 and / or reader device 120 may transmit reflected signal data associated with the reflected signal (e.g., transmitting the reflected signal data to server 130 via network 140, etc.). For example, reader 124 and / or reader device 120 may include a communication interface for such communication.

[0131] In some non-limiting embodiments or aspects, at least one reader 124 may include multiple readers. Additionally or alternatively, each reader 124 may be located at a location (e.g., a known location, a predetermined location, an optional location, a pre-selected location, and / or any combination thereof) within at least one site (e.g., at least one facility, and / or at least one building, etc.). For example, the location of each reader 124 may differ from the locations of all other readers 124 (e.g., each reader 124 may be located at a different location within one or more sites). In some non-limiting embodiments or aspects, the location of the medical device component 102 may be determined (e.g., determined by the reader 124, reader device 120, and / or server 130, etc.) based on the detection of the reader 124 of the medical device component 102 among the multiple readers 124 (e.g., each reader 124 may have a known location, and the location of the medical device component 102 may be determined to be close to (e.g., within the operating range of the reader) the respective reader 124 that detected the medical device component 102).

[0132] In some non-limiting embodiments or aspects, generator 122 and / or reader 124 may be included in a single device (e.g., reader device 120, etc.). Additionally or alternatively, generator 122 and / or reader 124 may share a single antenna (e.g., the antenna of reader device 120, etc.). In some non-limiting embodiments or aspects, generator 122 and / or reader 124 may be independent devices.

[0133] Server 130 may include one or more devices capable of receiving information from reader device 120, generator 122, and / or reader 124, and / or transmitting information to the reader device, generator, and / or reader (e.g., via network 140). For example, server 130 may include one or more computing devices, such as a server and / or a group of servers. In some non-limiting embodiments or aspects, server 130 is associated with facilities as described herein. In some non-limiting embodiments or aspects, server 130 may communicate with a data storage device, which may be located locally on server 130 or remotely connected to the server. In some non-limiting embodiments or aspects, server 130 may be able to receive information from the data storage device, store information in the data storage device, transmit information to the data storage device, or search for information stored in the data storage device.

[0134] In some non-limiting embodiments or aspects, server 130 may include a second communication interface configured (e.g., via network 140, etc.) to communicate with a first communication interface (e.g., communicating with the first communication interface of reader 124, and / or communicating with the first communication interface of reader device 120, 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, server 130 is configured to store the reflected signal data (e.g., storing the reflected signal data in a database, data storage device, memory, and / or any combination thereof, etc.).

[0135] In some non-limiting embodiments or aspects, each type of medical device component (e.g., the first medical device component 102a, and / or the second medical device component 102b, etc., as 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 corresponding resonance spectrum (e.g., the first resonance spectrum, and / or the second resonance spectrum, etc., as described herein). In some non-limiting embodiments or aspects, each mated combination of medical device components (e.g., the first medical device component 102b, etc., mating with the second medical device component 102a, as described herein) may have a corresponding resonance spectrum (e.g., the third resonance spectrum, etc., as 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 their respective resonance spectra. For example, server 130 may store a mapping of each type of medical device component (e.g., its unique identifier) ​​and / or each assembled combination of medical device components to their respective resonant spectra (e.g., a database, and / or a table, etc., which may be predetermined, and / or pre-selected, etc.).

[0136] In some non-limiting embodiments or aspects, a unique corresponding resonance spectrum may be assigned to each individual type of medical device component (e.g., the first medical device component 102a, and / or the second medical device component 102b, etc., as described herein), and / or each combination of mated medical device components, based on at least one rule. For example, the first rule may include that two different types of medical device components cannot be assigned to the same resonance spectrum (e.g., If I ≠ j, then F i ≠F j Where N can represent the total number of possible types of medical device components, i can represent the number of medical device components associated with the first type, and F i The resonant spectrum of a first-type medical device component can be represented, j can represent the number associated with a second-type medical device component, and F... j This could represent the resonant spectrum of a second type of medical device component. Additionally or alternatively, the second rule may include that when two types of medical device components (e.g., whether of the same or different types) are mated (e.g., physical connection, electrical connection, and / or electromagnetic coupling, etc.), they cannot have the resonant spectrum corresponding to any other two types of medical device components when mated (e.g., If i ≠ k and / or j ≠ l, then Φ(S) i ,S j )≠Φ(Sk ,S l ), where i can represent the quantity associated with the first type of medical device component, j can represent the quantity associated with the second type of medical device component, k can represent the quantity associated with the third type of medical device component, l can represent the quantity associated with the fourth type of medical device component, and S i This can represent the characteristics (e.g., geometric characteristics, and / or material characteristics, etc.) of at least one resonant structure associated with a first-type medical device component, S j This can represent the characteristics (e.g., geometric properties, and / or material properties, etc.) of at least one resonant structure associated with a second type of medical device component, S k This can represent the characteristics (e.g., geometric properties, and / or material properties, etc.) of at least one resonant structure associated with a third type of medical device component, S l The characteristic (e.g., geometric characteristics, and / or material characteristics, etc.) of at least one resonant structure associated with a fourth type of medical device component can be represented, and Φ can represent the resonant spectrum of the two resonant structures associated with the combined combination of the two types of medical device components. Additionally or alternatively, the third rule may include that a type of medical device component cannot have the corresponding resonant spectrum of any combination of the two types of medical device components (e.g., Where i can represent the quantity associated with the first type of medical device component, j can represent the quantity associated with the second type of medical device component, k can represent the quantity associated with the third type of medical device component, and F i S can represent the resonant spectrum of a component of a first-type medical device. j This can represent the characteristics (e.g., geometric properties, and / or material properties, etc.) of at least one resonant structure associated with a second type of medical device component, S k Φ can represent the characteristics (e.g., geometric characteristics, and / or material characteristics, etc.) of at least one resonant structure associated with a third type of medical device component, and Φ can represent the resonant spectrum of two resonant structures associated with the combination of the two types of medical device components after mating.

[0137] In some non-limiting embodiments or aspects, server 130 may perform and / or assist in inventory management. For example, a threshold (e.g., a minimum quantity, etc.) may be selected for the total number of each type of medical device component in one or more sites (e.g., pre-selected, pre-selected, and / or dynamically selected, etc.). Additionally or alternatively, since each type of medical device component can be uniquely identified based on its corresponding resonant spectrum, server 130 may determine the quantity of each type of medical device component within the one or more sites (e.g., based on reflected signal data received from multiple readers 124 within the one or more sites). In some non-limiting embodiments or aspects, if the total number of a corresponding type of medical device component meets a threshold (e.g., less than a minimum quantity, etc.), server 130 may determine that replenishment of the inventory of that corresponding type of medical device component may be necessary. For example, server 130 may transmit a notification indicating that replenishment of the inventory of a corresponding type of medical device component may be necessary (e.g., email, and / or text message, etc.). Additionally or alternatively, server 130 may automatically order additional inventory of the corresponding type of medical device component (e.g., automatically ordering via e-commerce, etc.). Additionally or alternatively, server 130 may initiate any suitable replenishment method, such as those implemented within a medical facility (e.g., requesting a cart to move between storage rooms, pharmacies, and / or care area sites where medical devices can be used). In some non-limiting embodiments or aspects, at least one local threshold (e.g., a minimum quantity) may be selected (e.g., predetermined, pre-selected, and / or dynamically selected, etc.) for the quantity of each type of medical device component at a corresponding location within the site. Additionally or alternatively, since each type of medical device component can be uniquely identified based on its corresponding resonant spectrum, server 130 may determine the quantity of each type of medical device component at a corresponding location within at least one site (e.g., based on reflected signal data received from multiple readers 124 within the at least one site). In some non-limiting embodiments or aspects, if the quantity of a corresponding type of medical device component at a corresponding location meets a threshold (e.g., less than a minimum quantity, etc.), server 130 may determine that replenishment of the inventory of the corresponding type of medical device component may be necessary, and / or that redistribution of the inventory of the corresponding type of medical device component may be necessary from other locations within the site. For example, as described herein, server 130 can send notifications and / or automatically order additional inventory.

[0138] For illustrative purposes, if a medical device component (e.g., the first medical device component 102a, and / or a syringe, etc.) is filled with medication (e.g., medication is contained in a pharmacy at a site) and is then transported to another location (e.g., an operating room at that site), the medical device component can be detected during transport and / or at the destination location by at least one reader 124 (e.g., any one of one or more readers 124 positioned along the path the medical device component may travel, and / or any one of one or more readers 124 that may be positioned at the destination location). In this way, the location of the medical device component can be determined and / or stored, as described herein. For example, the location of the corresponding reader 124 that recently detected the medical device component may be known (e.g., pre-selected, and / or predetermined, etc.). Additionally or alternatively, when the medical device component arrives at the destination location, it can be detected by at least one reader 124 positioned at or near that destination location (e.g., an operating room, etc.). Additionally or alternatively, if a drug-filled medical device component needs to be connected to a second medical device component (e.g., second medical device component 102b, and / or catheter, etc.), for example, to deliver the drug to a patient, the engagement between the drug-filled medical device component and the second medical device component can be detected, as described herein. Additionally or alternatively, after detecting a resonance spectrum associated with the engagement between the drug-filled medical device component and the second medical device component, if at least one reader 124 (e.g., located at or near the destination location) subsequently (e.g., within a predetermined selected (e.g., pre-selected, pre-selected, and / or dynamically selected, etc.) time period) detects a first resonance spectrum associated with the first medical device component and a second resonance spectrum associated with the second medical device component (e.g., and no longer detects a resonance spectrum associated with the engagement between these medical device components), it can be determined (e.g., detected, inferred, and / or assumed, etc.) that the medical device components are disconnected.

[0139] In some non-limiting embodiments or aspects, server 130 (and / or reader device 120 and / or reader 124) may perform and / or assist in prescriptive determination. For example, since the engagement of the first medical device component 102a and the second medical device component 102b can be detected based on the detection of a third spectrum (and / or the lack of engagement of the first medical device component 102a and the second medical device component 102b can be detected based on the detection of at least one of the first spectrum and / or the second spectrum without the need to detect the third spectrum), the connection and / or disconnection of multiple medical device components can be determined (e.g., detected, monitored, recorded, and / or stored, etc.). For example, server 130 (and / or reader device 120 and / or reader 124) may determine whether the first medical device component 102a and the second medical device component 102b are engaged based on reflected signal data, and / or may store reflected signal data with time data (e.g., timestamps, time and / or date data, etc.). In some non-limiting embodiments or aspects, the determined engagement of the first medical device component 102a and the second medical device component 102b (and / or the lack thereof, etc.) can be compared with guidelines and / or prescribed treatment protocols to determine their conformity. (For example, if the guidelines and / or prescribed treatment protocols require a period of connection between the two components (e.g., a period of time for flushing an IV catheter by connecting a syringe with saline solution to the IV catheter, and / or a period of time for infusing the fluid through the IV catheter by connecting a container of fluid (e.g., a bag) to the IV catheter), the timestamps associated with the engagement or lack thereof of these medical device components can be compared with the time periods of the guidelines and / or prescribed treatment protocols.) For example, these guidelines and / or prescribed treatment protocols can be stored in a database (e.g., a database local to server 130, or a database remotely connected to the server).

[0140] 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 reader device 120, the generator 122, and / or the reader 124, etc., may include any suitable frequency range. For example, the operating frequency may be in the ultra-wideband (UWB) range, and / or in the range of 3 GHz 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 reader device 120, the generator 122, and / or the reader 124, etc., may include any suitable distance. For example, the operating range (e.g., distance, etc.) may be less than 5 meters (m), less than 1 m, and / or 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 reader device 120, the generator 122, and / or the reader 124, etc., may include any suitable temperature range. For example, the operating temperature range may include -20 degrees Celsius (°C) to 80°C, etc.

[0141] In some non-limiting embodiments or aspects, in addition to RFID tags (e.g., RFID tags including integrated circuits (ICs) and / or ASICs), multiple resonant structures as described herein (e.g., a first antenna element 108a including at least one first resonant structure 104a, and / or a second antenna element 108b including at least one second resonant structure 104b, etc.) can also be used. For example, the resonant structures as described herein (e.g., a first antenna element 108a including at least one first resonant structure 104a, and / or a second antenna element 108b including at least one second resonant structure 104b, etc.) can be used to detect the mating of multiple medical device components, while at least one RFID tag can be used to identify each individual medical device component, etc.

Additionally or alternatively, antenna element 608 may include a metal strip 606 as described herein. In some non-limiting embodiments or aspects, resonant structure 604 may include at least one helical resonator (e.g., a first helical resonator) as described herein. Additionally or alternatively, the first resonant spectrum may include a first intrinsic frequency of the first helical resonator as described herein.

[0206] In some non-limiting embodiments or aspects, the longitudinal metal strip 666 (e.g., at least a portion of the longitudinal metal strip) may be arranged longitudinally (e.g., axially, and / or parallel to the axis of the medical device component, etc.) along the medical device component 602, as described herein. In some non-limiting embodiments or aspects, at least one scale marker resonant structure 664 may include a plurality of scale marker resonant structures 664, as described herein.

Additionally or alternatively, medical device component 602 may include longitudinal antenna element 668 in place of antenna element 608 (e.g., including longitudinal antenna element in the absence of antenna element, and / or including the longitudinal antenna element independent of the antenna element, etc.).

[0208] In some non-limiting embodiments or aspects, when accessing the medical device component 602 using an access 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 access signal may include a multi-frequency electromagnetic signal, and when accessing 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 spectrum to form a first attenuated electromagnetic signal, as described herein.

[0209] In some non-limiting embodiments or aspects, when accessing the medical device component 602 using an access signal, the longitudinal antenna element 668 (e.g., its scale-marked 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. For example, the access signal may include a multi-frequency electromagnetic signal, and when accessing the medical device component 602 using the multi-frequency electromagnetic signal, the longitudinal antenna element 668 (e.g., its scale-marked resonant structure 664) can attenuate at least one second frequency component of the multi-frequency electromagnetic signal corresponding to a second resonant spectrum to form a second attenuated electromagnetic signal, as described herein.

[0210] In some non-limiting embodiments or aspects, when a medical device component 602 (e.g., its mating element 610) is mated to a second medical device component (e.g., its second mating element), an antenna element 608 (e.g., its resonant structure 604) may be combined with a second antenna element (e.g., its second resonant structure) of the second medical device component to have a third resonant spectrum, as described herein.

[0211] For reference Figure 6B and Figure 6C , Figure 6B and 6C To and Figure 6A A coordinate graph of exemplary spectra of embodiments or aspects related to the non-limiting embodiments or aspects shown in Embodiment 600. (As shown...) Figure 6B and Figure 6C As shown, a coordinate graph can have a horizontal axis associated with frequency (f) and a vertical axis associated with amplitude (A).

[0212] refer to Figure 6B Access signal 612 may include a multi-frequency electromagnetic signal, as described herein. For example, access signal 612 may include a continuous-wave multi-frequency electromagnetic signal having a uniform amplitude and phase over a frequency range. In some non-limiting embodiments or aspects, access signal 612 may be the same as or similar to access signal 112.

[0213] refer to Figure 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 the following: amplitude attenuation, phase jump, frequency attenuation, and / or any combination thereof, corresponding to the second resonant spectrum (e.g., the second resonant spectrum associated with the longitudinal antenna element 668, and / or at least one scaled resonant structure 664 thereof), as described herein. For illustrative purposes, as Figure 6C As shown, the second reflected signal 614 may include amplitude attenuation around the natural frequency of each of the plurality of scale-marked resonant structures 664. For example, the second reflected signal 614 may include a first amplitude attenuation around a first natural frequency f1 (e.g., a first natural frequency f1 associated with the first scale-marked resonant structure 664, etc.), a second amplitude attenuation around a second natural frequency f2 (e.g., a second natural frequency f2 associated with the second scale-marked resonant structure 664, etc.), and an nth natural frequency f n (For example, the nth natural frequency f associated with the nth scale-marked resonance structure 664, etc.) n The nth amplitude decay around the ) and / or any combination thereof, etc.

[0214] In some non-limiting embodiments or aspects, each type of medical device component (e.g., first medical device component 102a, and / or second medical device component 102b, etc., as described herein) may have a unique identifier (e.g., a stock quantity unit (SKU), etc.). Additionally or alternatively, each of the N possible scale-marked resonance structures 664 may have a unique intrinsic frequency. In some non-limiting embodiments or aspects, each corresponding type of medical device component may be uniquely identified based on a unique subset of at most n scale-marked resonance structures 664 (e.g., where n may be less than or equal to N). For example, each of the N possible scale-marked resonant structures 664 can be associated with a bit, and if a corresponding subset includes a corresponding scale-marked resonant structure from the N possible scale-marked resonant structures 664 (e.g., if the second reflected signal 614 includes the inherent frequency of the corresponding scale-marked resonant structure from the N possible scale-marked resonant structures 664), the presence of the corresponding scale-marked resonant structure from the N possible scale-marked resonant structures 664 may be associated with a first logic value (e.g., 1 and / or 0, etc.). Additionally or alternatively, if a corresponding subset does not include a corresponding scale-marked resonant structure from the N possible scale-marked resonant structures 664 (e.g., if the second reflected signal 614 does not include the inherent frequency of the corresponding scale-marked resonant structure from the N possible scale-marked resonant structures 664), the absence of the corresponding scale-marked resonant structure 664 from the N possible scale-marked resonant structures 664 may be associated with a second logic value (e.g., 0 and / or 1, etc.). Therefore, each unique intrinsic frequency can be the same as or similar to a logical bit (e.g., the bit can be 1 (present) and / or 0 (absent), etc.). In some non-limiting embodiments or aspects, each possible permutation of a subset of up to n scaled resonant structures 664 can be associated with a number comprising multiple bits, each bit being associated with 1 (e.g., the corresponding intrinsic frequency exists) or 0 (the corresponding intrinsic frequency does not exist), etc. Additionally or alternatively, each possible permutation of a subset of up to n scaled resonant structures 664 (e.g., the number comprising multiple bits associated therewith) can be associated with a corresponding one of a plurality of unique identifiers for various types of medical device components. In some non-limiting embodiments or aspects, a mapping (e.g., a database, and / or a table, etc.) can be stored (e.g., stored via server 130, etc.), and this mapping can map each type of medical device component (e.g., its unique identifier) ​​to a respective possible permutation of a subset of up to n scaled resonant structures 664 (e.g., the number comprising multiple bits associated therewith). In some non-limiting embodiments or aspects, the total number of possible bits can be as high as 35 bits.Alternatively or additionally, the bit density per unit may include up to 5.88 bits / cm. 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 and / or up to 0.1 bits / cm 2 (e.g., based on the geometric characteristics of the resonant structure 664, the material properties of the resonant structure 664, and / or the operating frequency of the resonant structure 664, etc.).

In some non-limiting embodiments or aspects, label 750 may be adhered to a medical device component as described herein.

[0219] In some non-limiting embodiments or aspects, at least one tag resonant structure 754 may include a plurality of tag resonant structures 754, as described herein. In some non-limiting embodiments or aspects, the plurality of tag resonant structures 754 (and / or subsets thereof) may be arranged longitudinally (e.g., axially, and / or parallel to the axis of the medical device component, etc.) along a medical device component (e.g., the plurality of tag resonant structures may be arranged longitudinally along the medical device component when the tag 750 is adhered to the medical device component, etc.), as described herein.

In some non-limiting embodiments or aspects, the first tag antenna element 758a (e.g., a receiving antenna element) and the second tag antenna element 758b (e.g., a transmitting antenna element) may be cross-polarized. For example, a first tag antenna element 758a (e.g., a receiving antenna element) and a second tag antenna element 758b (e.g., a transmitting antenna element) can be arranged (e.g., disposed, etc.) on a tag 750 such that when the tag 750 is adhered to a medical device component (e.g., wound around a cylindrical medical device component, etc.), the first tag antenna element 758a (e.g., a receiving antenna element) can be orthogonally facing the second tag antenna element 758b (e.g., a transmitting antenna element).

In some non-limiting embodiments or aspects, one or more steps of the multiple steps of process 800 may be performed by reader device 120 (e.g., one or more devices of reader device 120, such as generator 122, and / or reader 124, etc.) (e.g., fully performed, and / or partially performed, etc.). In some non-limiting embodiments or aspects, one or more steps of the multiple steps of process 800 may be performed by another system, another device, another set of systems, or another set of devices (e.g., fully performed, and / or partially performed, etc.), which is separate from or includes the reader device 120. The other system, the other device, the other set of systems, or the other set of devices may be, for example, a medical device component 102 (e.g., one or more components of medical device component 102, such as a first medical device component 102a and / or a second medical device component 102b, etc.) and / or a server 130 (e.g., one or more devices of server 130), etc.

Additionally or alternatively, the second medical device component 102b may have at least one second resonant structure 104b, as described herein. In some non-limiting embodiments or aspects, the second resonant structure 104b may have a second resonant spectrum. In some non-limiting embodiments or aspects, the second resonant spectrum may be the same as the first resonant spectrum, as described herein. In some non-limiting embodiments or aspects, the second resonant spectrum may be different from the first resonant spectrum, as described herein.

[0224] like Figure 8As shown, at step 806, process 800 may include mating a first medical device component with a second medical device component. For example, the first medical device component 102a and the second medical device component 102b may mat to form a medical device assembly (e.g., medical device assembly 102), as described herein.
