[0098] 3A-3H, 4A-4D, and 5A-5C illustrate non-limiting embodiments or aspects of flow sensor system 150. Referring to FIGS. 3A-3H, 4A-4D, and 5A-5C, flow sensor system 150 can include two main assemblies that are assembled together prior to use: flow sensor 160 and base 180. In some non-limiting embodiments or aspects, flow sensor 160 can be a disposable flow sensor that is mateable with reusable base 180.

[0099] The flow sensor system 150 can reduce bedside medication errors during bolus administration. The flow sensor system 150 can provide a record of the bolus administration and measure the bolus administration electronically, which allows for the bolus administration to be monitored and automatically documented as part of the patient's medical record. The flow sensor system 150 can provide a warning when a bolus administration that is inconsistent with the patient's medical record is about to occur.

[0100] The flow sensor system 150 can be a handheld infusion site with an interactive interface for syringe-infused IV drug delivery and direct electronic medical record documentation. The base 180 can include a durable, reusable reader base with a touchscreen display and a separate, disposable, consumable flow sensor 160.

[0101] In some non-limiting embodiments or aspects, flow sensor 160 may include a flow tube 162, at least one sensor 170 configured to characterize at least one property of the fluid within flow tube 162, and / or flow sensor electrical contacts 172 in electrical communication with at least one sensor 170. Flow tube 162 may include a fluid inlet 163 at a first end of flow tube 162, a fluid outlet 164 at a second end of flow tube 162 opposite the first end of flow tube 162, a fluid injection port 165 between the first and second ends of flow tube 162, and a valve 166 (e.g., a manual valve, etc.) configured to control the flow of fluid within flow tube 162.

[0102] In some non-limiting embodiments or aspects, the base 180 may include one or more processing units 204, base electrical contacts 192 in electrical communication with the one or more processing units 204, a near field communication device (e.g., a communication interface 214, a near field communication (NFC) receiver, etc.), and / or a display 194 (e.g., an input component 210, an output component 212, a touch panel display configured to receive user input from a user, etc.). The flow sensor electrical contacts 172 may be in electrical communication with the base electrical contacts 192 when the flow sensor is connected (e.g., connected, attached, mounted, etc.) to the base 180.

[0103] In some non-limiting embodiments or aspects, the base 180 includes an opening 196 configured to receive the flow sensor 160, and the flow sensor 160 is configured to slidingly engage with the opening 196 of the base 180.

[0104] In some non-limiting embodiments or aspects, the at least one sensor 170 may include a first ultrasonic transducer or piezo element 170 disposed at an upstream position of the flow tube 162, and a second ultrasonic transducer or piezo element 170 disposed at a downstream position of the flow tube 162. The first and second piezo elements 170 may be configured to transmit a flow signal indicative of the flow of fluid (e.g., a fluid drug) within the flow tube 162. In some non-limiting embodiments or aspects, the first ultrasonic transducer or piezo element and the second ultrasonic transducer or piezo element 170 are annular in shape and surround the flow tube 162 at their respective attachment points. In some non-limiting embodiments or aspects, the first ultrasonic transducer or piezo element and the second ultrasonic transducer or piezo element 170 are mounted a preselected distance apart from each other. The first and second ultrasonic transducers or piezo elements 170 may be in electrical communication with one or more processing units 204 (e.g., via electrical contacts 172, 192, etc.) when the flow sensor 160 is connected to the base 180. For example, the base 180 may interact with the first and second ultrasonic transducers or piezo elements 170 in the flow sensor 160 to measure the displacement of fluid through the flow sensor 160.

[0105] In some non-limiting embodiments or aspects, valve 166 may be configured to transition between a number of different states and may control at least one of fluid flow between fluid inlet 163 and fluid outlet 164, fluid flow between fluid inlet 163 and fluid injection port 165, fluid flow between fluid injection port 165 and fluid outlet 164, or any combination thereof. For example, valve 166 may include a three-way stopcock valve, and / or the like.

[0106] In some non-limiting embodiments or aspects, the one or more processing devices 204 may be programmed and / or configured to automatically detect the connection of the flow sensor 160 to the base 180. For example, when a user attaches the flow sensor 160 to the reader base 180, the reader base 180 automatically detects the attachment of the flow sensor 160. As an example, a mechanical button or switch on the base 180 in electrical communication with the one or more processing devices may be activated by the connection / detachment of the flow sensor 160 to the base 180 and send a signal to the one or more processing devices 204 indicating the connection / detachment status of the flow sensor 160 to the base 180.

[0107] In some non-limiting embodiments or aspects, the one or more processing devices 204 are programmed and / or configured to automatically detect connection of the syringe 102 to the fluid injection port 165 of the flow sensor 160. For example, when a user inserts the syringe 102 having a needleless luer connector into the fluid injection port 165, the reader base 180 may automatically detect the presence of the syringe upon connection to the fluid injection port 165 and begin decoding the tag 104 (e.g., via a near-field communication device, etc.) to record the information content (e.g., medication information, etc.) of the tag 104. As an example, the flow sensor system 150 may include an electronic and mechanical interface that interacts with the syringe 102 when inserted into the fluid injection port 165 and detects the presence of the syringe 102 upon insertion by the user. In such an example, a mechanical button or switch on flow sensor 160, which is in electrical communication with one or more processing devices (e.g., via electrical contacts 172 and 192), may be activated by connection / disconnection of syringe 102 to fluid inlet port 165 and send a signal indicating the connection / disconnection status of syringe 102 to one or more processing devices 204. In some non-limiting embodiments or aspects, tag or label 104, which may include an NFC tag embedded therein, may be manually placed on the body of syringe 102 using a standard label printer. For example, the label printer may be used to encode the NFC tag at the time of printing. Additionally or alternatively, NFC encoding may be performed using a separate NFC tag encoding unit.

[0108] In some non-limiting embodiments or aspects, the near field communication device is configured to automatically communicate with the near field communication tag 104 on the syringe 102 via a near field communication connection when the near field communication tag 104 is brought within communication range of the near field communication device. In some non-limiting embodiments or aspects, the near field communication device is configured to automatically communicate with the near field communication tag 104 on the syringe 102 via a near field communication connection in response to the base 180 detecting connection of the syringe 102 to the fluid injection port 165. For example, the tag 104 can be detected using NFC when positioned radially adjacent to the antenna of the near field communication device of the base 180. As an example, the base 180 can include an integrated, radially positioned NFC antenna to record the syringe's label tag 104 and read and decode encoded information therefrom. In such an example, the NFC antenna and label tag are optimized to eliminate false detection of adjacently positioned syringes having NFC tag labels (e.g., an NFC antenna radially attached to the base 180 and a label tag 104 on the syringe barrel of the syringe 102 can be used to transmit encoded label information from the syringe label tag 104 to the reader base 180, etc.).

[0109] In some non-limiting embodiments or aspects, the one or more processing devices 204 may be programmed and / or configured to automatically detect the state of the valve 166 when the flow sensor 160 is connected to the base 180. For example, the base 180 may automatically determine the state or position of the valve 166 when a user manually toggles the state or position of the valve 166. As an example, an electronic and / or mechanical interface may interact with the valve 166 to monitor the position or state of the valve. In such an example, a mechanical button or switch on flow sensor 160, which is in electrical communication with one or more processing devices (e.g., via electrical contacts 172 and 192), may be actuated to change the position or state of valve 166 and send a signal to one or more processing devices 204 indicating the state or position of valve 166 (e.g., indicating that fluid flow is permitted between fluid inlet 163 and fluid outlet 164, between fluid inlet 163 and fluid injection port 165, between fluid injection port 165 and fluid outlet 164, or any combination thereof).

[0110] In some non-limiting embodiments or aspects, the one or more processors 204 are programmed and / or configured to determine whether to record information related to at least one attribute of the fluid in the flow tube 162 based on the detected state of the valve 166. For example, a user may toggle the state or position of the valve 166 to enable recording of flow measurements and / or to enable the flow of IV fluid. As an example, the one or more processors 204 of the base 180 may determine when to record flow measurements and ignore measurements of the IV fluid flow rate and redundant amounts when IV fluid is drawn into the syringe 102 and then injected through the flow sensor 160.

[0111] In some non-limiting embodiments or aspects, the flow sensor 160 is inserted in line with the IV line 106 between the fluid source and the patient. For example, the disposable flow sensor 160 can be inserted in line with the IV line 106, allowing IV fluid to pass directly to the patient's extension line catheter. In some non-limiting embodiments or aspects, the valve 166 is configured to allow the syringe 102 to draw IV fluid from the IV line 106 and deliver the drawn IV fluid in a pushing manner through the flow sensor 160 to flush the flow sensor 160 and the extension line of previously delivered medication volume. In some non-limiting embodiments or aspects, the flow sensor 160 can be integrated into the IV 106 (e.g., in the IV extension set line) without a separate detachable connector. In some non-limiting embodiments or aspects, a fluid flow stopcock valve can be placed in line before and / or after the flow sensor 160, and / or additional functionality for incorporating workflow operations can be provided within the interactive display 194 of the base 180. For example, by placing the flow sensor 160 in series with the IV line 106, the dead space problem associated with a parallel connection due to lack of flushing may be eliminated.

[0112] In some non-limiting embodiments or aspects, the base 180 includes an optical scanner configured to read a barcode label (e.g., a barcode label on a patient's wristband, a barcode label on the flow sensor 160, etc.).

[0113] In some non-limiting embodiments or aspects, display 194 includes a touchscreen display configured to accept user input from a user. For example, display 194 may include an interactive graphical user interface configured to display the current state of the internal functions of reader base 180, the current state of the infusion site, and / or prompts for user interaction, and reader base 180 may interact with the user via a touchscreen display, audio, voice commands, tactile feedback, and / or the like (e.g., to orient the user to the current state, request user input, etc.). Thus, by incorporating display 194 into base 180, the user does not need to shift their attention from base 180 to interact with display 194.

[0114] In some non-limiting embodiments or aspects, the base 180 includes a wireless communication device configured to communicate information related to at least one attribute of the fluid within the flow tube 162 to the remote computing device 110. For example, the base 180 may communicate information and / or data with the remote computing device 110 to record the occurrence of drug delivery in a patient medical record (e.g., a patient medical record associated with a barcode label on a patient's wristband that was scanned by an optical scanner of the base 180).

[0115] 4A, 5A, 6A-6C, 7A, 7B, and 8, in some non-limiting embodiments or aspects, the near field communication device of the base 180 may include a curved coil antenna 600.

[0116] The size of the syringe 102 may vary (e.g., syringe sizes may range from 1 mL to 60 mL, etc.). The location of the near field communication tag 104 on the syringe 102 may vary. For example, a user may attach the near field communication tag 104 to a variety of different locations on the body of the syringe 102. The variability between the location of the tag 104 and the size of the syringe 102, combined with the curvature of the body syringe 102, may make reading the encoded data from the tag 104 more difficult and / or present a significant burden to the user. For example, HF RFID / NFC works by creating an inductive coupling of electromagnetic waves in the 13.56 MHz range to power the HF RFID / NFC tag, which transmits the encoded information back to a transmit coil antenna. As an example, the transmit coil antenna should transmit enough energy to power the tag 104, and the tag coil antenna within the tag 104 should receive enough energy to power and transmit encoded information stored in the tag 104 back to the transmit coil antenna. If the tag 104 receives enough energy, the transmit coil antenna may be flat and the tag 104 may be positioned parallel to the transmit coil antenna to power the tag 104. The received energy may be based on the distance to the transmit coil antenna of the tag 104 and / or the orientation of the transmit coil antenna relative to the tag 104 (e.g., offset and / or angle at which the tag 104 faces the transmit coil antenna). For example, as the angle between the coil antenna of the tag 104 and the transmit coil antenna approaches 90 degrees or 270 degrees, the antenna energy received by the tag 104 may decrease to zero. As an example, a formula for calculating the amount of energy received by the tag 104 from the transmit coil antenna may be defined according to COSINE(angle). Therefore, when the angle between the transmitting coil antenna and the coil antenna of the tag 104 reaches 90 degrees or 270 degrees, the energy received by the tag 104 is zero and the tag 104 is not powered.In this way, if the tag 104 is present on the syringe 102 and the tag 104 can be placed anywhere on the syringe 102 by the user, there is a possibility that the angle may be close enough to or at a position of zero energy where the data encoded on the tag 104 cannot be read by the near field communication device.

[0117] Non-limiting embodiments or aspects of the flow sensor system 150 including the curved coil antenna 600 may reduce and / or eliminate the 90 degree and / or 270 degree angle between the transmitting coil antenna of the near field communication device of the base 180 and the tag 104 on the syringe 102 by surrounding and / or encircling the syringe 102 with the curved coil antenna 600. For example, with reference to FIG. 8 , the curved coil antenna 600 may enable electromagnetic waves to be transmitted from the near field communication device of the base 180 in a radial direction relative to the syringe 102 when the syringe 102 is connected to the flow sensor 160 and the flow sensor 160 is connected to the base 180, thereby covering a larger area of ​​the syringe 102 (e.g., acceptance criteria for a successful reading depending on the circumferential area of ​​the curved coil antenna 600, etc.). As an example, the curved coil antenna 600 may allow electromagnetic waves to be transmitted radially from the near field communication device of the base 180 to surround an NFC HF RFID tag on a circular syringe. In contrast, a flat NFC coil antenna may cause the electromagnetic waves to be transmitted orthogonally to the coil antenna, which may result in the NFC HF RFID tag not aligning with the transmitted electromagnetic waves (e.g., particularly if the tag is at 90 degrees to the waves) and not providing power or transmitting information encoded in the tag back to the transmitting NFC coil antenna. Thus, the curved NFC coil antenna may allow electromagnetic waves to be transmitted in more directions relative to the NFC HF RFID tag (e.g., for NFC communications based on the ISO 14443 and / or ISO 15693 NFC standards, which describe physical layer and protocol layer technologies, etc.), thereby reducing and / or preventing the 90-degree and / or 270-degree angle between the transmitting coil antenna and the tag.

[0118] In some non-limiting embodiments or aspects, the fluid injection port 165 of the flow sensor 160 may extend from the flow tube 162 in a first direction parallel to the longitudinal axis of the fluid injection port 165, and the curved coil antenna 600 in the near field communication device of the base 180 may be curved radially relative to the longitudinal axis of the fluid injection port 165 when the flow sensor 160 is connected to the base 180. For example, the fluid injection port 165 may be configured to connect to the syringe 102, and when the syringe 102 is connected to the fluid injection port 165 of the flow sensor 160 and the flow sensor 160 is connected to the base 180, the curved coil antenna 600 may be curved radially around the syringe 102 and / or extend in a first direction parallel to the longitudinal axis of the fluid injection port 165.

[0119] 4A and 6A-6C, the curved coil antenna 600 extends in a direction parallel to a plane defined by the surface of the display 194 of the base 180 (e.g., in a direction parallel to the longitudinal axis of the syringe 102 when the syringe 102 is connected to the flow sensor 160, and the flow sensor 160 is connected to the base 180, etc.). In some non-limiting embodiments or aspects, as shown in FIG. 5A, for example, the curved coil antenna 600 extends in a direction not parallel to (e.g., perpendicular to) the plane defined by the surface of the display 194 of the base 180 (e.g., in a direction perpendicular to) the plane defined by the surface of the display 194 of the base 180 (e.g., in a direction perpendicular to the plane). In such an example, when syringe 102 is connected to flow sensor 160 and flow sensor 160 is connected to base 180, curved coil antenna 600 may at least partially surround syringe 102. In some non-limiting embodiments or aspects, the curvature of the curved coil antenna may correspond to the circumferential area of ​​a 60 mL syringe, and / or the like.

[0120] 3A-3H and 9A-9E, which are flowcharts of non-limiting embodiments or aspects of processes for using a flow sensor system. In some non-limiting embodiments or aspects, one or more steps of the process are performed (e.g., completely, partially, etc.) by flow sensor system 150 (e.g., one or more devices of flow sensor system 150). In some non-limiting embodiments or aspects, one or more steps of the process are performed (e.g., completely, partially, etc.) by another device or devices separate from or including flow sensor system 150, such as remote computing device 110 (e.g., one or more devices of a system of remote computing device 110).

[0121] As shown in FIG. 9A, in step WS5.2, the process for using the flow sensor system includes scanning a flow sensor label attached to the disposable flow sensor to decode a flow sensor identifier associated with the flow sensor. For example, an optical scanner (e.g., “reader” in FIGS. 9A-9E) in the base 180 for the disposable flow sensor 160 (e.g., “sensor” in FIGS. 9A-9E) can scan the flow sensor label (e.g., flow sensor barcode) attached to the disposable flow sensor and decode the flow sensor identifier associated with the flow sensor. As an example, scanning the barcode of the disposable flow sensor 160 allows the base 180 (and / or remote computing device 110) to determine whether the disposable flow sensor 160 is still in use, and if so, by which patient.

[0122] As shown in FIG. 9A , in step WS4, the process for using the flow sensor system includes scanning a patient label affixed to the patient to decode a patient identifier associated with the patient. For example, an optical scanner in the base 180 for the disposable flow sensor 160 can scan a patient label (e.g., a patient wristband, patient barcode, etc.) attached to the patient to decode a patient identifier associated with the patient. As an example, a smart device (e.g., base 180, etc.) can be used to electronically scan each of the smart IV consumables (e.g., disposable flow sensor 160, etc.) and the patient wristband provided by the EMR vendor, for example, using a barcode scanner. The smart device can communicate the patient identifier information (e.g., the patient MRN) and the unique identification number of the smart IV consumable to a virtual server (e.g., remote computing device 110, etc.) on the hospital network. The virtual server can use the patient identification information to create a bidirectional link to an application on the hospital information system associated with the patient that is related to the functionality of the smart device and the smart consumable. Once a bidirectional link is established, the virtual server can associate the link with the unique identification number of the smart IV consumable, and if the smart device is detached, the smart device or a new, separate device can be re-associated by scanning the smart consumable. In contrast, if a patient is associated solely by electronics, such as associating a patient with a barcode reader, re-association by scanning the patient's wristband is necessary when the device cannot be used (e.g., due to a dead battery), and if the wristband is not accessible (e.g., during surgery), manual entry of the patient ID may need to be performed, which can be subject to error. For example, a device may need to be associated with a patient record by having a case assigned to it by the EMR, manually selecting the patient through a user interface on the device, or directly associating the smart device with the patient, such as through an electronic scan. Furthermore, if improperly detached, the device may also be at risk of being used to the wrong patient record based on incorrect patient record information.

[0123] 9A, in step WS5.3, the process for using the flow sensor system includes connecting a disposable flow sensor to a base. For example, disposable flow sensor 160 can be connected to base 180.

[0124] 9A, in step WS5.1, the process for using the flow sensor system includes integrating a disposable flow sensor into an IV line. For example, disposable flow sensor 160 can be integrated into IV line 106.

[0125] 9B , the disposable flow sensor 160 is integrated into the IV line 106 before scanning the flow sensor label, scanning the patient label, and connecting the disposable flow sensor 160 to the base 180. For example, scanning the flow sensor label, scanning the patient label, and integrating the disposable flow sensor 160 into the IV line 106 before connecting the disposable flow sensor 160 to the base 180 allows the clinician to associate the patient with another unsuspecting patient identification and / or scan and attach the disposable flow sensor 160 in another sequential step, which adds value when preparing the patient for a procedure, for example, in an operating room. As an example, scanning the patient ID before connection ensures that the IV line 106 does not impede the user when scanning the patient ID, which may be ideal for outpatient procedures where a new IV line is integrated into the disposable flow sensor 160 in situ for the procedure.

[0126] 9C , the disposable flow sensor 160 is integrated into the IV line 106 after scanning the flow sensor label, scanning the patient label, and connecting the disposable flow sensor 160 to the base 180. For example, integrating the disposable flow sensor 160 into the IV line 106 after scanning the flow sensor label, scanning the patient label, and connecting the disposable flow sensor 160 to the base 180 may allow the clinician to prepare the base 180 and the disposable flow sensor 160 prior to interaction with the patient and / or existing IV, which may provide added value to existing IV maintenance procedures that do not need to be performed in the presence of the patient if the clinician has time prior to the arrival of an inpatient.

[0127] 9A, in steps WS4, WS5.2, and / or WS5.4, the process for using the flow sensor system includes communicating the flow sensor identifier and the patient identifier to a remote computing device and associating the flow sensor identifier with the patient identifier. For example, the base 180 may communicate the flow sensor identifier and the patient identifier to the remote computing device 110, which may associate the flow sensor identifier with the patient identifier in a database.

[0128] 9D , the base 180 may communicate a request for the status of the disposable flow sensor 160 associated with the flow sensor identifier to the remote computing device 110 and receive an indication of the status of the disposable flow sensor 160 associated with the flow sensor identifier from the remote computing device 110. For example, the indication of the status of the disposable flow sensor 160 may include an indication of whether the flow sensor identifier of the disposable flow sensor 160 is associated with the patient's patient identifier.

[0129] In some non-limiting embodiments or aspects, and still referring to FIG. 9D, the base 180 can communicate a base identifier associated with the base 180 to the remote computing device 110 in a request for the status of the disposable flow sensor 160 associated with the flow sensor identifier, and the remote computing device 110 can associate the base identifier with the flow sensor identifier and the patient identifier.

[0130] 9A, in steps WS4 and / or WS6, the process for using the flow sensor system includes communicating a request for patient-related information associated with a patient identifier, receiving the patient-related information, and displaying the patient-related information. For example, and referring also to FIG. 9E, the base 180 may communicate a request for patient-related information associated with a patient identifier to the remote computing device 110, receive the patient-related information from the remote computing device 110, and display the patient-related information on the display.

[0131] In some non-limiting embodiments or aspects, the information associated with the patient includes at least one of a list of drug allergies associated with the patient and a list of medications being prepared for the patient.

[0132] 9E , the near field communication device of the base 180 may scan the near field communication tag 104 attached to the syringe 102 to decode a medication identifier associated with the medication in the syringe 102, and the base 180 may compare the medication identifier to at least one of a list of medication allergies associated with the patient and a list of medication doses being prepared for the patient. For example, the display 194 of the base 180 may display an alert related to the administration of the medication to the patient based on the comparison. In some non-limiting embodiments or aspects, the near field communication device includes a near field communication (NFC) receiver, and the near field communication tag includes an NFC tag.

[0133] Thus, non-limiting embodiments or aspects of a process for using a flow sensor system may allow more steps to be performed on a patient at the point of care, providing advantages over methods requiring interaction with an EMR screen. Additionally, non-limiting embodiments or aspects of a process for using a flow sensor system may allow a patient to be associated with a smart consumable attached to the patient's IV line rather than the electronics alone (such as, for example, base 180), which provides greater confidence that device data will be linked to the appropriate patient because the smart IV consumable is directly connected to the patient (via the IV), and may allow a smart device to be replaced with another device that can be associated with the patient by scanning the smart consumable, as opposed to having to re-scan the patient's wristband.

[0134] While embodiments or aspects have been described in detail for purposes of illustration and description, it should be understood that such detail is solely for that purpose and that the disclosure or aspects are not limited to the disclosed embodiments or aspects, but rather are intended to cover modifications and equivalent arrangements within the spirit and scope of the appended claims. For example, it should be understood that the present disclosure contemplates, to the extent possible, that one or more features of any embodiment or aspect may be combined with one or more features of any other embodiment or aspect. Indeed, any of these features may be combined in ways not specifically recited in the claims and / or disclosed in the specification. While each dependent claim listed below may depend directly on only one claim, the disclosure of possible implementations includes each dependent claim in combination with all other claims in the claim set.
